2.    Summary of Significant Accounting Policies


Basis of Presentation


The unaudited condensed consolidated financial statements contained in this Quarterly Report on Form 10-Q have been prepared in accordance with the rules and regulations of the Securities and Exchange Commission ("SEC"(“SEC”) and, therefore, certain information and disclosures normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("(“U.S. GAAP"GAAP”) have been omitted.


In the opinion of management, the information reflects all adjustments necessary to make the results of operations for the interim periods a fair statement of such operations. All such adjustments are of a normal recurring nature. Interim results are not necessarily indicative of results for the full year. The condensed consolidated balance sheet atas of December 31, 20162021 has been derived from the audited consolidated financial statements at that date but does not include all information and footnotes required by U.S. GAAP for complete financial statements. These unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements included in the Company'sCompany’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016.2021.


Use of Estimates


The preparation of the Company'sCompany’s unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period.


Reported amounts and notefootnote disclosures reflect the overall economic conditions that are most likely to occur and anticipated measures management intends to take. Actual results could differ materially from those estimates. Estimates and assumptions are reviewed quarterly. Any revisions to accounting estimates are recognized in the period in which the estimates are revised and in any future periods affected.


Cash, Cash Equivalents and Short-term Investments


Cash and cash equivalents consist of cash and highly liquid securities with original maturities at the date of acquisition of ninety days or less. Investments with an original maturity of more than ninety days are considered short-term investments and have been classified by management as available-for-sale. These investments are classified as current assets, even though the stated maturity date may be one year or more beyond the current consolidated balance sheet date, which reflects management’s intention to use the proceeds from sales of these securities to fund its operations, as necessary. Such investments are carried at fair value, and the unrealized gains and losses are reported as a component of accumulated other comprehensive income (loss) in stockholders’shareholders’ equity until realized. Realized gains and losses from the sale of available-for-sale securities, if any, are determined on a specific identification basis.    



Concentration of Credit Risk


The Company invests its excess cash in accordance with its investment policy. The Company'sCompany’s investments are comprised primarily of commercial paper and debt instruments of financial institutions, corporations, U.S. government-sponsored agencies and the U.S. Treasury. The Company mitigates credit risk by maintaining a diversified portfolio and
5

limiting the amount of investment exposure as to institution, maturity and investment type. Financial instruments that potentially subject the Company to significant credit risk consist principally of cash equivalents and short-term investments.


Segment ReportingRevenue Recognition


Operating segments are componentsThe Company recognizes revenue in connection with certain collaboration and license agreements in accordance with the guidance of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision-maker for purposes of making decisions regarding resource allocation and assessing performance. To date,Revenue From Contracts With Customers, Accounting Standards Codification (“ASC”) Topic 606 (“Topic 606”). Under Topic 606, the Company has viewedrecognizes revenue when its operations and managed its business as one segment operating primarilycustomer obtains control of promised goods or services, in an amount that reflects the consideration that the entity expects to receive in exchange for those goods or services.  To determine revenue recognition for arrangements the Company determines are within the scope of Topic 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the United States.contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the Company satisfies a performance obligation.  The Company only applies the five-step model to contracts when it is probable that the Company will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer.  At contract inception, once the contract is determined to be within the scope of Topic 606, the Company assesses the goods or services promised within each contract and determines those that are performance obligations, and assesses whether each promised good or service is distinct.  The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.


Leases

The Company determines if an arrangement is a lease at inception. Lease right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. For operating leases with an initial term greater than 12 months, the Company recognizes operating lease right-of-use assets and operating lease liabilities based on the present value of lease payments over the lease term at the commencement date. Operating lease right-of-use assets are comprised of the lease liability plus any lease payments made and excludes lease incentives. Lease terms include options to renew or terminate the lease when the Company is reasonably certain that the renewal option will be exercised or when it is reasonably certain that the termination option will not be exercised. For the Company’s operating leases, if the interest rate used to determine the present value of future lease payments it not readily determinable, the Company estimates its incremental borrowing rate as the discount rate for the lease. The Company’s incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments, and in similar economic environments. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company has elected the practical expedient to not separate lease and non-lease components.

Net lossLoss per shareShare


Basic net loss per common share is calculated by dividing the net loss by the weighted-average number of common shares outstanding during the period, without consideration for common share equivalents.equivalents as they are anti-dilutive. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common shares and common share equivalents outstanding for the period.period, as well as certain shares that are contingently issuable. Common share equivalents outstanding, determined using the treasury stock method, are comprised of shares that may be issued under the Company’s stock option and warrant agreements.agreements, as well as restricted stock units and performance stock units.


The following table presents the weighted averageweighted-average number of common share equivalents, calculated using the treasury stock method, as well as certain shares that are contingently issuable, not included in the calculation of diluted net loss per share due to the anti-dilutive effect of the securities:

3.Recently Issued and Recently Adopted and Recently Issued Accounting Pronouncements


From time to time, new accounting pronouncements are issued by the Financial Accounting Standards Board ("FASB"(“FASB”) or other standard setting bodies that are adopted by the Company as of the specified effective date.

Recently Adopted Accounting Pronouncements

In January 2017, the FASB issued ASU No. 2017-01, Clarifying the Definition of a Business, which clarifies and provides a more robust framework to use in determining when a set of assets and activities is a business. The amendments in this update should be applied prospectively on or after the effective date. This update is effective for annual periods beginning after December 15, 2017, and interim periods within those periods. Early adoption is permitted for acquisition or deconsolidation transactions occurring before the issuance date or effective date and only when the transactions have not been reported in issued financial statements. The Company early adopted this standard effective April 1, 2017 in connection with an immaterial collaboration agreement it entered into during the quarter. The adoption of this standard did not have a material effect on its consolidated financial statements.

In March 2016, the FASBhas evaluated recently issued ASU 2016-09, Compensation-Stock Compensation (Topic 718). The new guidance changes the accounting pronouncements and simplifies various aspects of the accounting for share-based payments to employees. The guidance allows for a policy election to account for forfeitures as they occur or based on an estimated number of awards that are expected to vest. ASU 2016-09 is effective for annual periods beginning after December 15, 2016, with early adoption permitted. Effective January 1, 2017, the Company adopted the provisions of ASU 2016-09. The impact of this adoption was limited to the accounting for forfeitures of certain stock based awards, which is adopted on a modified retrospective basis. Upon adoption, the Company will no longer estimate forfeitures and will instead account for forfeitures as they occur. This policy election was made to allow simplification of the accounting for share-based awards. The cumulative effect of adoption was an increase to both additional paid-in capital and accumulated deficit of $0.4 million.
In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements-Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. Under the new guidance, management is required to assess an entity’s ability to continue as a going concern, and to provide related footnote disclosures in certain circumstances. The provisions of this ASU are effective for annual periods ending after December 15, 2016, and for annual and interim periods thereafter; early adoption is permitted. The Company adopted this guidance as of December 31, 2016 and the adoption did not require any additional disclosures in the Company's consolidated financial statements for the year ended December 31, 2016 or for the current period.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which will replace numerous requirements in U.S. GAAP, including industry-specific requirements, and provide companies with a single revenue recognition model for recognizing revenue from contracts with customers. The core principle of the new standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. In August 2015, the FASB approved a proposal to defer the effective date of the guidance until annual and interim reporting periods beginning after December 15, 2017. Although the Company currently does not havebelieve any revenue contracts, the Company early adopted this standard effective January 1, 2017 using the full retrospective method of adoption so that, in the event the Company enters into any revenue contracts, the contracts will be accounted for under the new guidance from inception of the contract.

Recently Issued Accounting Pronouncements

In July 2017, the FASB issued ASU 2017-11, Earnings Per Share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); Derivatives and Hedging (Topic 815): (Part I) Accounting for Certain Financial Instruments with Down Round Features, (Part II) Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Non-controlling Interests with a Scope Exception.The ASU allows companies to exclude a down round feature when determining whether a financial instrument (or embedded conversion feature) is considered indexed to the entity’s own stock. As a result, financial instruments (or embedded conversion features) with down round features may no longer be required to be classified as liabilities. A company will recognize the value of a down round feature only when it is triggered and the strike price has been adjusted downward. For equity-classified freestanding financial instruments, such as warrants, an entity will treat the value of the effect of the down round, when triggered, as a dividend and a reduction of income available to common shareholders in computing basic earnings per share. For convertible instruments with embedded conversion features containing down round provisions, entities will recognize the value of the down round as a beneficial conversion discount to be amortized to earnings. The guidance in ASU 2017-11 is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted, and the guidance is to be applied using a full or modified retrospective approach. The Company does not anticipate that the adoption of ASU 2017-11 will have a material impact on itsthe Company’s condensed consolidated financial statements unless a transaction occurs that would need to be evaluated under this guidance at which time the Company will assess the impact of this standard.

In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation, to provide clarity and reduce both 1) diversity in practice and 2) cost and complexity when applying the guidance in Topic 718 to a change in the terms or conditions of a share-based payment award.  ASU 2017-09 provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting under Topic 718.  The amendments in ASU 2017-09 are effective for fiscal and interim reporting periods in fiscal years beginning after December 15, 2017.  Early adoption is permitted, including adoption in any interim period.  The amendments in ASU 2017-09 should be applied prospectively to an award modified on or after the adoption date.  The Company does not anticipate that the adoption of ASU 2017-09 will have a material impact on its consolidated financial statements unless a transaction occurs that would need to be evaluated under this guidance at which time the Company will assess the impact of this standard.


In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). Under the new guidance, lessees are required to recognize most lease assets and lease liabilities on their balance sheets and record expenses on their income statements in a manner similar to current accounting. The new guidance is effective for fiscal years beginning after December 15, 2018, with early adoption permitted. The primary impact of this new accounting guidance will be related to the Company's facilities lease and the Company is currently evaluating the impact that this guidance will have on its consolidated financial statements and related financial statement disclosures.

In January 2016, the FASB issued ASU 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. The new guidance enhances the reporting model for financial instruments and includes amendments to address aspects of recognition, measurement, presentation and disclosure. The update to the standard is effective for public companies for interim and annual periods beginning after December 15, 2017. The Company does not believe the adoption of this standard will have a material impact on its financial position, results of operations or related financial statement disclosures.

As of possible other-than-temporary impairment. Factors considered in determining whether a loss is other-than-temporary includeMarch 31, 2022 and December 31, 2021, the length of time and extent to which fair value has been less than the cost basis, the financial condition and near-term prospects of the investee,unrealized losses for available-for-sale investments were non-credit related, and the Company’s intent and ability to hold the investment for a period of time sufficient to allow for any anticipated recovery in market value. The Company does not intend to sell anythe investments prior tobefore recovery of their amortized cost basis, which may be at the time of maturity. As of March 31, 2022 and December 31, 2021, no allowance for credit losses was recorded. During the three months ended March 31, 2022 and 2021, the Company did not recognize any investmentsimpairment losses related to investments.

The long-term investment balance of $3.1 million and $8.2 million as of March 31, 2022 and December 31, 2021, respectively, is comprised of 588,235 shares of ORIC Pharmaceuticals, Inc. (“ORIC”) common stock. As of March 31, 2022 the investment is carried at fair value which is based on the closing price of ORIC’s common stock on the last trading day of the reporting period; unrealized gains and losses are recorded in other expense, net on the Company’s condensed consolidated statements of operations and comprehensive loss. As of December 31, 2021, the fair value was based on the last trading day of the reporting period and was adjusted for a discount for lack of marketability due to an unrealized loss position.eighteen-month lock-up period which expired during the first quarter of 2022. The Company currently does not intend to sell ORIC shares within 12 months from March 31, 2022. See Note 4 - Fair Value Measurements.


5.4.    Fair value measurementsValue Measurements


The Company has certain financial assets and liabilities recorded at fair value which have been classified as Level 1, 2 or 23 within the fair value hierarchy as described in the accounting standards for fair value measurements.


The authoritative guidance for fair value measurements defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or the most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Market participants are buyers and sellers in the principal market that are (i) independent, (ii) knowledgeable, (iii) able to transact, and (iv) willing to transact. The guidance prioritizes the inputs used in measuring fair value into the following hierarchy:
7

Table of Contents
Level 1- Quoted prices (unadjusted) in active markets for identical assets or liabilities;


Level 2- Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable; and


Level 3- Unobservable inputs in which little or no market activity exists, therefore requiring an entity to develop its own assumptions about the assumptions that market participants would use in pricing.

The Company’s investments in Level 1 assets are valued based on publicly available quoted market prices for identical securities as of September 30, 2017March 31, 2022 and December 31, 2016.2021. The Company determines the fair value of Level 2 related securities with the aid of valuations provided by third parties using proprietary valuation models and analytical tools. These valuation

Table of Contents
models and analytical tools use market pricing or prices for similar instruments that are both objective and publicly available, including matrix pricing or reported trades, benchmark yields, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids and/or offers.

The Company’s long-term investment in ORIC as of December 31, 2021 was considered a Level 3 fair value measurement and utilized a combination of the Asian Protective Put Option and Finnerty Put Option fair value techniques with unobservable inputs of 69% volatility and an expected term of 0.1 years to determine the discount for lack of marketability of 5.0%. During the three months ended March 31, 2022, the eighteen-month lock-up period expired, and because ORIC common stock is quoted in an active market, it meets the criteria of a Level 1 investment. The Company transferred the investment in ORIC from a Level 3 fair value measurement to a Level 1 fair value measurement. There were no transfers between fair value measurement levels during the three and nine months ended September 30, 2017 or the year ended December 31, 2016.2021.

7.    License and Collaboration Agreements

BeiGene Agreement

Terms of Agreement

On January 7, 2018, the Company and BeiGene Ltd. (“BeiGene”) entered into a Collaboration and License Agreement (the “BeiGene Agreement”), pursuant to which the Company and BeiGene agreed to collaboratively develop sitravatinib in Asia (excluding Japan and certain other countries), Australia and New Zealand (collectively, the “BeiGene Licensed Territory”). Under the BeiGene Agreement, the Company granted BeiGene an exclusive license to develop, manufacture and commercialize sitravatinib in the BeiGene Licensed Territory, with the Company retaining exclusive rights for the development, manufacture and commercialization of sitravatinib outside the BeiGene Licensed Territory.

As consideration for the rights granted to BeiGene under the BeiGene Agreement, BeiGene paid the Company a non-refundable, non-creditable up-front fee of $10.0 million. BeiGene is also required to make milestone payments to the Company of up to an aggregate of $123.0 million upon the first achievement of specified clinical, regulatory and sales milestones. The BeiGene Agreement additionally provides that BeiGene is obligated to pay the Company royalties at tiered percentage rates ranging from mid-single digits to 20 percent on annual net sales of licensed products in the BeiGene Licensed Territory, subject to reduction under specified circumstances. The BeiGene Agreement also provides that the Company will supply BeiGene with sitravatinib for use in BeiGene’s development activities in the BeiGene Licensed Territory.

The BeiGene Agreement will terminate upon the expiration of the last royalty term for the licensed products, which is the latest of (i) the date of expiration of the last valid patent claim related to the licensed products under the BeiGene Agreement, (ii) ten years after the first commercial sale of a licensed product and (iii) the expiration of any regulatory exclusivity as to a licensed product. BeiGene may terminate the BeiGene Agreement at any time by providing 60 days prior written notice to the Company. Either party may terminate the BeiGene Agreement upon a material breach by the other party that remains uncured following 60 days after the date of written notice of such breach or upon certain bankruptcy events. In addition, the Company may terminate the BeiGene Agreement upon written notice to BeiGene under specified circumstances if BeiGene challenges the licensed patent rights.

Revenue Recognition

The Company evaluated the BeiGene Agreement under Topic 606. At the time it entered into the BeiGene Agreement, the Company determined the transaction price was equal to the up-front fee of $10.0 million. The transaction price was allocated to the performance obligations on the basis of the relative stand-alone selling price estimated for each performance obligation. In estimating the stand-alone selling price for each performance obligation, the Company developed assumptions that require judgment and included forecasted revenues, expected development timelines, discount rates, probabilities of technical and regulatory success and costs for manufacturing clinical supplies. As such, of the up-front fee, the Company allocated $9.5 million to the license to the Company’s intellectual property, bundled with the associated know-how, and the remaining $0.5 million to the initial obligation to supply sitravatinib for clinical development in the BeiGene Licensed Territory.

Licenses of Intellectual Property.   The license to the Company’s intellectual property, bundled with the associated know-how, represents a distinct performance obligation. The license and associated know-how was transferred to BeiGene during the three months ended March 31, 2018 and, therefore during 2018, the Company recognized the full revenue amount of $9.5 million related to this performance obligation as license and collaboration revenues in its condensed consolidated statements of operations and comprehensive loss.

Manufacturing Supply Services.  The Company’s initial obligation to supply sitravatinib for clinical development in the BeiGene Licensed Territory represents a distinct performance obligation, and the initial obligation was satisfied in 2020 and, therefore, this $0.5 million initial supply obligation was fully recognized as license and collaboration revenues as of December 31, 2020. Although the initial performance obligation was satisfied, BeiGene may request additional sitravatinib in the future for clinical development in the BeiGene Licensed Territory. The Company recognized revenue when BeiGene obtained control of the goods, over the period of the obligation. No revenue related to this performance obligation was recognized for the three months ended March 31, 2022 and March 31, 2021, respectively.

Table of Contents
Milestone Payments. The Company is entitled to development milestones under the BeiGene Agreement and certain regulatory milestone payments which are paid upon receipt of regulatory approvals within the BeiGene Licensed Territory. No milestone payments were earned during the three months ended March 31, 2022 and March 31, 2021, respectively. The Company evaluated whether the remaining milestones are considered probable of being reached and determined that their achievement is highly dependent on factors outside of the Company’s control. Therefore, these payments have been fully constrained and are not included in the transaction price. At the end of each subsequent reporting period, the Company will re-evaluate the probability of achievement of each milestone and any related constraint, and if necessary, adjust its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect the reported amount of license and collaboration revenues in the period of adjustment.

Royalties.  As the license is deemed to be the predominant item to which sales-based royalties relate, the Company will recognize revenue when the related sales occur. No royalty revenue was recognized during the three months ended March 31, 2022 or 2021.

Pfizer Agreement

In October 2014, the Company entered into a drug discovery collaboration and option agreement with Array BioPharma, Inc. (“Array,” acquired by Pfizer Inc. (“Pfizer”) in July 2019) whereby Array provided services to facilitate the discovery, optimization and development of small molecule compounds that bind and specifically inhibit KRAS G12C. In June 2017, the two parties entered into a second, separate discovery collaboration and option agreement whereby Array provided services to facilitate the discovery, optimization and development of small molecule compounds that bind and specifically inhibit KRAS G12D. Both agreements established an option mechanism which enabled the Company to elect an exclusive worldwide license under the technology for the development and commercialization of certain products based on these compounds.

Under these agreements, following the joint discovery periods, which have since concluded, the Company exercised its options to retain exclusive worldwide licenses to develop, manufacture and commercialize inhibitors of KRAS G12C and KRAS G12D, including, but not limited to, MRTX849 (adagrasib is the provisionally filed name for MRTX849) and MRTX1133. Under each agreement, Pfizer is entitled to potential development milestone payments of up to $9.3 million from the Company, and tiered sales milestone payments of up to $337.0 million based upon worldwide net sales, and tiered royalties in the high single digits to mid-teens on worldwide net sales of products arising from the collaborations. Under the agreements, the Company has incurred immaterial depreciation$9.5 million in development milestone payments from inception through March 31, 2022.

The royalty term for each agreement is payable on a country-by-country and product-by-product basis, and separately will terminate at the later of (i) the date of expiration of the last valid patent claim within the collaboration patent rights or the Pfizer background technology covering such product in the country in which such product is sold at the time of such sale, or (ii) ten years after the first commercial sale of such product in such country. The Company may terminate each agreement at any time by providing 60 days prior written notice to Pfizer. Either party may terminate each agreement upon a material breach by the other party that remains uncured following 60 days after the date of written notice of such breach or upon certain bankruptcy events.

No expenses were incurred under these agreements with Pfizer for the three months ended March 31, 2022 or 2021, respectively.

ORIC Pharmaceuticals Agreement

Terms of Agreement

On August 3, 2020, the Company entered into a license agreement with ORIC Pharmaceuticals, Inc. (“ORIC”) pursuant to which the Company granted to ORIC an exclusive, worldwide license to develop and commercialize the Company’s allosteric polycomb repressive complex 2 (“PRC2”) inhibitors for all indications (the “ORIC Agreement”). In accordance with the terms of the ORIC Agreement, in exchange for such license, ORIC issued 588,235 shares of its common stock (the “Shares”) to the Company on August 3, 2020. The Shares were issued under a stock issuance agreement entered into between ORIC and the Company, dated August 3, 2020. During the eighteen-month period following the date of the stock issuance agreement, the Company was subject to certain transfer restrictions. ORIC is not obligated to pay the Company milestone payments or royalty payments under the ORIC Agreement.

11

Table of Contents
Unless terminated earlier, the ORIC Agreement will continue in effect on a country-by-country and licensed product-by-licensed product basis until the later (a) the expiration of the last valid claim of a licensed patent covering such licensed product in such country or (b) ten years after the first commercial sale of such licensed product in such country. Following the expiration of the ORIC Agreement, ORIC will retain its licenses under the intellectual property the Company licensed to ORIC on a royalty-free basis. The Company and ORIC may each terminate the ORIC Agreement if the other party materially breaches the terms of such agreement, subject to specified notice and cure provisions, or enters into bankruptcy or insolvency proceedings. The Company may terminate this agreement if ORIC challenges any of the patent rights licensed to ORIC by the Company or if ORIC discontinues development of licensed products for a specified period of time. ORIC also has the right to terminate the ORIC Agreement without cause by providing prior written notice to the Company.

Revenue Recognition

The Company accounted for the ORIC Agreement under Topic 606 and identified the granting of an exclusive, worldwide license to develop and commercialize the Company’s allosteric PRC2 inhibitors for all indications as a distinct performance obligation since ORIC can benefit from the license on its own by developing and commercializing the underlying product using its own resources.

In determining the transaction price, the Company received the Shares as non-cash consideration. The Company allocated the entire transaction price to the distinct performance obligation described above, and the license and related know-how was transferred to ORIC during the third quarter of 2020. Therefore, the Company recognized the entire transaction price of $11.4 million during 2020 and classified the amount as license and collaboration revenues in its condensed consolidated statements of operations and comprehensive loss.

The Shares are carried at fair value and are recorded on the condensed consolidated balance sheet as a long-term investment. Any change in fair value is recorded within other expense, net on the condensed consolidated statements of operations and comprehensive loss.

Zai Agreement

Terms of Agreement

On May 28, 2021, the Company and Zai Lab Ltd. (“Zai”) entered into a Collaboration and License Agreement (the “Zai Agreement”), pursuant to which the Company and Zai agreed to collaboratively develop adagrasib in China, Hong Kong, Macau and Taiwan (collectively, the “Zai Licensed Territory”). Under the Zai Agreement, the Company granted Zai the rights to research, develop, manufacture and exclusively commercialize adagrasib in all indications in the Zai Licensed Territory, with the Company retaining exclusive rights for boththe development, manufacture and commercialization of adagrasib outside the Zai Licensed Territory and certain co-commercialization, manufacture, and development rights in the Zai Licensed Territory. Zai is obligated to participate in selected global, registration-enabling clinical trials and enroll patients in the Zai Licensed Territory at Zai’s expense.

As consideration for the rights granted to Zai under the Zai Agreement, Zai agreed to pay the Company a non-refundable, non-creditable up-front fee of $65.0 million. Under the Zai Agreement, the Company is entitled to potential development and regulatory-based milestone payments of up to $93.0 million, and tiered sales milestone payments of up to $180.0 million based on net sales in the Zai Licensed Territory. The Zai Agreement additionally provides that Zai is obligated to pay to the Company royalties at tiered percentage rates ranging from the high-teens to the low-twenties on annual net sales of licensed products in the Zai Licensed Territory, subject to reduction under specified circumstances. The Zai Agreement also provides that the Company will supply Zai with adagrasib for use in Zai’s development activities in the Zai Licensed Territory at Zai's expense.

The Zai Agreement will terminate on a licensed product-by-licensed product basis and on a region-by-region basis in the Zai Licensed Territory, upon the later to occur of (i) the date of expiration of the last valid claim covering such licensed product in such region, (ii) the date that is ten years after the date of the first commercial sale in such region and (iii) the expiration date of any regulatory exclusivity for such licensed product in such region, or for a co-commercialized product on the date the parties agree to terminate such co-commercialization, or in its entirety upon the expiration of all payment obligations under the Zai Agreement. Zai may terminate the Zai Agreement at any time by providing 12 months’ notice to the Company. Either party may terminate the Zai Agreement upon a material breach by the other party that remains uncured or upon certain bankruptcy events. In addition, the Company may terminate the Zai Agreement if Zai challenges the licensed patent rights.

Revenue Recognition

The Company evaluated the Zai Agreement under Topic 606. The Company determined that two performance obligations existed: (1) the license to intellectual property, bundled with the associated know-how and (2) the Company's initial obligation to supply adagrasib for clinical development in the Zai Licensed Territory. At the time it entered into the Zai Agreement, the Company determined the transaction price was equal to $66.6 million, which includes the up-front fee and other incidental amounts. In estimating the stand-alone selling price for each performance obligation, the Company developed assumptions that require judgment and included forecasted revenues, expected development timelines, discount rates, probabilities of technical and regulatory success, forecasted costs for manufacturing clinical supplies and cost savings related to Zai's participation in selected trials. The Company allocated the full transaction price to the license to the Company’s intellectual property, bundled with the associated know-how. The Company concluded the variable payments related to the Company’s initial obligation to supply adagrasib for clinical development in the Zai Licensed Territory relate specifically to the Company’s efforts to satisfy this performance obligation and the obligation to provide the initial clinical supply approximates the stand-alone selling price. Payments under the Zai Agreement are subject to foreign tax withholdings.

Licenses of Intellectual Property.   The license to the Company’s intellectual property, bundled with the associated know-how, represents a distinct performance obligation. The license and associated know-how was transferred to Zai during the three months ended September 30, 20172021 and, 2016therefore during 2021, the Company recognized the full revenue amount of $66.6 million as license and $0.1collaboration revenues and $3.3 million as income tax expense in its condensed consolidated statements of operations and comprehensive loss.

Manufacturing Supply Services.  The Company’s initial obligation to supply adagrasib for bothclinical development in the nineZai Licensed Territory represents a distinct performance obligation. As such, the Company will recognize revenue when Zai obtains control of the goods. The Company recognized $0.7 million revenue related to this performance obligation for the three months ended September 30, 2017March 31, 2022. The Company may also become responsible for manufacturing adagrasib for commercial supply and 2016.will receive reimbursement that approximates stand-alone selling prices.


Milestone Payments. The Company is entitled to development milestone payments and certain regulatory and sales milestone payments which are paid upon achievement of the development milestones, upon receipt of regulatory approvals and annual net sales thresholds within the Zai Licensed Territory under the Zai Agreement. No milestone payments were earned during the three months ended March 31, 2022. The Company evaluated whether or not the milestones are considered probable of being reached and determined that their achievement is highly dependent on factors outside of the Company’s control. These payments have been fully constrained and therefore are not included in the transaction price. At the end of each subsequent reporting period, the Company will re-evaluate the probability of achievement of each milestone and any related constraint and, if necessary, adjust its estimate of the overall transaction price. Any such adjustments will be recorded on a cumulative catch-up basis, which would affect the reported amount of license and collaboration revenues in the period of adjustment.

Royalties.  As the license is deemed to be the predominant item to which sales-based royalties relate, the Company will recognize revenue when the related sales occur. No royalty revenue was recognized during the three months ended March 31, 2022.

9.    Commitments and Contingencies


On June 30, 2020, the Company entered into an amended and restated lease agreement (the “Amended and Restated Lease”) for office and laboratory space located in San Diego, California, for the Company’s corporate headquarters. The Amended and Restated Lease supersedes in its entirety the original lease agreement for the Company’s future corporate headquarters dated as of August 22, 2019. The Amended and Restated Lease has a lease term of 12 years (“Lease Term”), unless terminated earlier. The Lease Term has an initial abatement period, and the initial base rent payable will be approximately $0.6 million per month following the abatement period, which amount will increase by 3% per year over the Lease Term. The Company also received incentives from the landlord for tenant improvements. During 2020, the underlying asset was available for use by the Company to construct tenant improvements and therefore, the Lease Term was considered to have commenced.

The Amended and Restated Lease is considered to be an operating lease, and the Amended and Restated Lease indicates the interest rate applicable to the lease is 12% and, therefore, the Company used a discount rate of 12% to calculate the value of its lease payments over the Lease Term. As of March 31, 2022, the condensed consolidated balance sheet includes an operating right-of-use asset of $37.2 million and a total operating lease liability of $48.7 million, of which $2.9 million is considered a current lease liability and included in other accrued expenses, and $45.8 million is included in non-current lease liability. As of December 31, 2021, the consolidated balance sheet includes an operating right-of-use asset of $37.7 million and an operating lease liability of $47.2 million, of which $1.3 million is considered a current lease liability and included in other accrued expenses, and $45.9 million is included in non-current lease liability. For the three months ended March 31, 2022 and 2021, the Company recorded $1.9 million and $2.0 million in operating lease expense, respectively.

Overview

Company Overview


Mirati Therapeutics, Inc. is a clinical-stage oncology company developing targeted drug productsnovel therapeutics to address the genetic epigenetic and immunological promoters of cancer. Our precision oncology

We have two KRAS inhibitor programs. Adagrasib is an investigational, selective, specific, potent and orally available KRAS G12C inhibitor in clinical development as a monotherapy and in combination with other agents. Adagrasib is the provisionally filed nonproprietary name for MRTX849. MRTX1133 is an investigational, selective, specific and potent KRAS G12D inhibitor in preclinical development.

Sitravatinib is an investigational spectrum-selective kinase inhibitor designed to potently inhibit receptor tyrosine kinases (“RTK”s) and enhance immune responses through the inhibition of immunosuppressive signaling.

MRTX1719 is an internally discovered investigational synthetic lethal PRMT5 inhibitor designed to specifically target the PRMT5/methylthioadensoine (MTA) complex in clinical development.

The Company also has additional preclinical programs utilize next-generation genomic testing to identifyof potentially first-in-class and select cancer patients who are most likely to benefit from targeted drug treatment. In immuno-oncology, we are advancing clinical programs where the ability of our product candidates to improve the immune environment of tumor cells may enhance and expand the efficacy of existing immunotherapy medicines when given in combination. Our pre-clinical programs includebest-in-class product candidates specifically designed to address mutations and tumors where few treatment options exist. We approach eachall of our discovery and development programs with a singular focus: to translate our deep understanding of the molecular drivers of cancer into better drugstherapies and better outcomes for patients.


Mirati’s clinical pipeline consistsKRAS Inhibitor Programs
The RAS family of three product candidates: glesatinib, sitravatinibgenes is the most commonly mutated oncogene and mocetinostat. Glesatinibmutations in this gene family occur in up to approximately 25% of all human cancers. Among the RAS family members, mutations most frequently occur in KRAS (approximately 85% of all RAS family mutations). Tumors characterized by KRAS mutations are commonly associated with poor prognosis and resistance to therapy. Nonclinical studies have demonstrated that cancer cells exhibiting KRAS mutations are highly dependent on KRAS function for cell growth and survival. Our KRAS inhibitor programs are focused on the discovery and development of small molecule compounds that target KRAS G12C and G12D. We are pursuing development of our KRAS G12C and KRAS G12D inhibitor programs in both single agent and rational combination approaches.

Adagrasib, a selective KRAS G12C inhibitor
Adagrasib, our lead KRAS G12C compound, is aan investigational, selective, specific, potent inhibitor of MET and Axl receptor tyrosine kinase families ("RTKs")orally available KRAS G12C inhibitor and is currentlyin clinical development varying from Phase 1 through Phase 3. Adagrasib is designed to directly inhibit KRAS G12C mutations. KRAS G12C mutations are present in approximately 14% of non-small cell lung cancer (“NSCLC”) adenocarcinoma patients, 3-4% of colorectal cancer (“CRC”) patients, 2% of pancreatic cancer patients, as well as smaller percentages of several other difficult-to-treat cancers.

We received U.S. Food and Drug Administration (“FDA”) authorization of our investigational new drug application (“IND”) for adagrasib in November 2018, and, in January 2019, we initiated the dose escalation phase of KRYSTAL-1, a Phase 1/2 multiple expansion cohort clinical trial evaluating adagrasib in patients with advanced solid tumors that harbor KRAS G12C mutations both in monotherapy and in combination with other anticancer therapies. Following single agent dose escalation, the KRYSTAL-1 trial was expanded into multiple cohorts in which adagrasib is being evaluated both in a Phase 2 clinical trialmonotherapy and in combination with other compounds in patients with NSCLC, CRC and those with other tumors that carry the KRAS G12C mutation.

In December 2021, we completed our New Drug Application (“NDA”) submission to the FDA for adagrasib for the treatment of patients with non-small cell lung cancerpreviously treated KRAS G12C-mutated NSCLC who have received prior systemic therapy. In February 2022, the FDA accepted the NDA and assigned a Prescription Drug User Fee Action (“NSCLC”PDUFA”) characterized by specific MET mutations. Sitravatinib is a multi-targeted RTK inhibitor thatdate of December 14, 2022. The NDA is being testedreviewed by the FDA for Accelerated Approval (Subpart H), which allows for the approval of drugs that treat serious conditions, and that fill an unmet medical need based on a surrogate endpoint. In addition, this application is being reviewed under the FDA Real-Time Oncology Review pilot program, which aims to explore a more efficient review process that ensures safe and effective treatments are made available to patients as early as possible. Adagrasib has also achieved Breakthrough Therapy Designation as a single agent in a Phase 1b clinical trialpotential treatment for patients with NSCLC who harbor the KRAS G12C mutation following prior systemic therapy. The Company also has an Expanded Access Program for adagrasib for the treatment of eligible patients with KRAS G12C-mutated cancers regardless of tumor type in the United States.

The KRYSTAL-1 trial is evaluating the combination of adagrasib and a PD-1 inhibitor (pembrolizumab) in patients with NSCLC, the combination of adagrasib and other tumor types defined by alterationsa pan-EGFR inhibitor (afatinib) in RET, CBLpatients with advanced NSCLC, and CHR4q12. Both glesatinibthe combination of adagrasib and sitravatinib are intended to treat specific mutations that drive the growth of cancer or are implicatedan anti-EGFR antibody (cetuximab) in cancer drug resistance or pathogenic processes such as tumor angiogenesis.

Sitravatinib is alsopatients with CRC. In 2020, we initiated KRYSTAL-2, a potent inhibitor of both VEGF and TAM (Tyro, Axl, and Mer) RTKs, which we believe may enhance anti-tumor immunity when combined with checkpoint inhibitors. Pre-clinical studies have demonstrated that sitravatinib can change the tumor microenvironment from a tolerogenic to an immunogenic state, improving the body’s anti-tumor immune response by reducing T-cell and macrophage suppressor effects. We arePhase 1/2 clinical trial evaluating the potentialcombination of sitravatinibadagrasib and a SHP-2 inhibitor (TNO-155) in patients with advanced NSCLC and advanced CRC. In 2021, we initiated KRYSTAL-14, a Phase 1/2 clinical trial evaluating the combination of adagrasib and a SOS1 inhibitor (BI 1701963) in patients with advanced NSCLC, and we initiated KRYSTAL-16, a Phase 1/1b clinical trial evaluating the combination of adagrasib and a CDK4/6 inhibitor (palbociclib) in patients with advanced solid tumors with KRAS G12C mutation. The KRYSTAL-2 and KRYSTAL-14 clinical trials are no longer enrolling patients.

In the fourth quarter of 2021, we announced preliminary results from the Phase 1b cohort of the KRYSTAL-1 trial evaluating the combination of adagrasib and a PD-1 inhibitor (pembrolizumab) in eight patients with KRAS G12C-mutated first-line NSCLC. The preliminary results support moving forward with a 400mg twice daily dose (“BID”) of adagrasib with full dose pembrolizumab, which is being evaluated in an ongoing Phase 2 clinical trial. The Phase 1b data showed adagrasib 400mg BID plus pembrolizumab had a manageable tolerability profile, with no observed Grade 4 or Grade 5 adverse events. Of the seven patients evaluable for a response as of October 21, 2021, four had a confirmed RECIST-defined partial response and one additional patient, who is still on study, experienced 49% tumor regression in the first scan, which allowed for tumor resection prior to enhanceachieving a RECIST-defined confirmed response. The disease control rate (“DCR”) was 100%, with all seven patients exhibiting tumor regression ranging from 37% to 92%. With a median follow up of 9.9 months, five of the seven patients remained on treatment, as of the data cutoff date, and expandhad been on treatment for 8 to 11 months.

On September 20, 2021, we announced that we completed an analysis in the intent-to-treat population of the registration enabling cohort of KRYSTAL-1, the Phase 1/2 clinical efficacytrial evaluating adagrasib at 600mg BID as a monotherapy treatment for patients in at least 2nd line NSCLC. The analysis showed an objective response rate (“ORR”) of immune checkpoint inhibitors in43% and a DCR of 80%, based on central independent review, as of June 15, 2021.

In the third quarter of 2021, we amended KRYSTAL-7, the Phase 2 clinical trial evaluating the combination of adagrasib at 400mg BID and a PD-1 inhibitor (pembrolizumab) in patients with NSCLC stratified by <1% Tumor Proportion Score (“TPS”) score and ≥1% TPS score.

In the first quarter of 2021, we initiated two registration-enabling Phase 3 clinical trials. The first clinical trial, KRYSTAL-12, is evaluating adagrasib as a monotherapy randomized against docetaxel in patients with 2nd line NSCLC. The
17

Table of Contents
second clinical trial, KRYSTAL-10, is evaluating the combination of adagrasib and an anti-EGFR antibody (cetuximab) randomized against chemotherapy in patients with 2nd line CRC.

On September 19, 2021, at the European Society for Medical Oncology Congress 2021, we presented preliminary results from the cohort of the KRYSTAL-1 Phase 1/2 clinical trial evaluating adagrasib at 600mg BID as both a monotherapy treatment and in combination with cetuximab for patients with heavily pretreated colorectal cancer harboring a KRAS G12C mutation.

As of May 25, 2021, the adagrasib monotherapy arm (n=46) had a median follow up of 8.9 months. Of the evaluable patients (n=45), preliminary results showed an investigator assessed response rate (“RR”) of 22%, including one unconfirmed partial response (“PR”), and a DCR of 87%; the median duration of response (“DOR”) was 4.2 months. In all enrolled patients, the median progression free survival (“PFS”) was 5.6 months (95% confidence interval (“CI”): 4.1,8.3).

As of July 9, 2021, the adagrasib plus cetuximab arm (n=32) had a median follow up of 7 months. Of the evaluable patients (n=28), preliminary results showed an investigator assessed RR of 43%, including two unconfirmed PRs and a DCR of 100%. After the data cutoff date, of the two unconfirmed PRs, follow up scans showed one patient had a confirmed PR, and the second patient progressed.

Adagrasib monotherapy and in combination with cetuximab was well-tolerated in this study, with a manageable safety profile. Grade 3/4 treatment related adverse events (“TRAEs”) were observed in 30% of patients treated with adagrasib alone, and in 16% of patients treated with the combination. Treatment related adverse events led to treatment discontinuation in 6% of patients who received combination therapy and in none (0%) of those who received adagrasib monotherapy. No Grade 5 TRAEs were observed in either treatment arm.

On October 9, 2021, at the 33rd EORTC-NCI-AACR Symposium on Molecular Targets and Therapeutics, we presented preliminary results from a cohort of the KRYSTAL-1 clinical trial evaluating adagrasib at 600mg BID as monotherapy for patients with pancreatic ductal adenocarcinoma harboring a KRAS G12C mutation. arm (n=12). Of the evaluable patients (n=10), preliminary results showed an investigator assessed RR of 50%, including an unconfirmed PR, and a DCR of 100%.

Preliminary efficacy data was assessed as of August 30, 2020 in six patients with advanced solid tumors, other than NSCLC and CRC, treated with adagrasib as a monotherapy at 600mg BID dose from a Phase 1/1b cohort. One patient each with pancreatic, ovarian, endometrial and cholangiocarcinoma tumors were treated and had a confirmed PR to therapy. Two appendiceal cancer patients had stable disease and all six eligible patients remained on treatment.

Adagrasib Development in Collaboration with Zai Lab Ltd. (“Zai”)

In May 2021, we entered into a Collaboration and License Agreement with Zai (the “Zai Agreement”). Under the Zai Agreement, we granted Zai the right to research, develop, manufacture and exclusively commercialize adagrasib in all indications in China, Macau, Hong Kong and Taiwan (collectively, the “Zai Licensed Territory”), with Mirati retaining exclusive rights for the development, manufacture and commercialization of adagrasib outside the Zai Territory and certain co-commercialization, manufacture, and development rights in the Zai Licensed Territory.

MRTX1133, a selective KRAS G12D inhibitor

MRTX1133, our lead KRAS G12D compound, has been identified as a clinical development candidate and is an investigational, selective, specific and potent inhibitor of KRAS G12D, and is currently in preclinical development. KRAS G12D mutations have been detected in over 25 different types of cancer, including pancreatic, colon, lung and endometrial adenocarcinoma. The prevalence of cancers harboring KRAS G12D mutations exceeds the prevalence of KRAS G12C positive cancers by greater than two-fold and is an area of significant unmet medical need.

On October 25, 2020 we announced initial preclinical in vivo data from MRTX1133. Based on preclinical analyses, MRTX1133 has a projected human half-life of approximately 50 hours and exhibits a low propensity for drug interactions or off-target pharmacology. MRTX1133 demonstrated tumor regression in multiple in vivo tumor models, including pancreatic and colorectal cancers. MRTX1133 has a low predicted target plasma concentration, based on its potency and high unbound fraction, and our goal is to achieve near complete and sustained target inhibition and maximal anti-tumor activity. We have prioritized a long-acting IV injectable drug product strategy, including liposome-based formulations, that are designed to
18

optimize and extend the duration of KRAS G12D target inhibition as we progress towards IND-enabling studies. We are also continuing to evaluate strategies to enhance oral absorption to potentially enable development of a solid oral dose form.
Sitravatinib

Sitravatinib is a spectrum-selective kinase inhibitor in Phase 3 clinical development and is designed to potently inhibit receptor tyrosine kinases (“RTK”s), including TAM family receptors (TYRO3, Axl, Mer), split family receptors (VEGFR2, KIT) and RET. Sitravatinib’s potent inhibition of TAM and split family RTKs may overcome resistance to checkpoint inhibitor therapy through targeted reversal of an immunosuppressive tumor microenvironment, enhancing antigen-specific T cell response and expanding dendritic cell-dependent antigen presentation. There are over 100,000 2nd or 3rd line NSCLC patients in the United States and Europe, who have derived prior clinical benefit following treatment with a PD-(L)1 inhibitor, with approximately 70,000 of these patients being of the non-squamous histology.

Sitravatinib in Combination with Nivolumab

As an immuno-oncology agent, sitravatinib is being evaluated in combination with nivolumab Bristol Myers Squibb’s(OPDIVO®), Bristol-Myers Squibb Company’s (“BMS”) anti-PD-1 checkpoint inhibitor, in patients with NSCLC and metastatic renal cell carcinoma. 

Our third candidate is mocetinostat, an orally-bioavailable, Class 1 selective histone deacetylase ("HDAC") inhibitor. Mocetinostat acts through epigenetic mechanisms and has demonstrated preclinically the ability to block the effects of immune suppressive cells that counter the immune system’s ability to fight tumors and reduce the effectiveness ofwho have experienced documented disease progression following treatment with a checkpoint inhibitors. Mocetinostatinhibitor. Sitravatinib is also being evaluateddeveloped in certain Asian territories in collaboration with BeiGene, Ltd. (“BeiGene”) which is evaluating sitravatinib in combination with tislelizumab, BeiGene’s anti-PD-1 checkpoint inhibitor, in a number of advanced solid tumors.

In April, we completed enrollment in a Phase 23 clinical trial in 2nd line non-squamous NSCLC patients whose tumors have progressed on prior therapy with platinum-chemotherapy in combination with durvalumab, MedImmune Limited’s ("MedImmune") anti-PD-L1a checkpoint inhibitor foror 3rd line non-squamous NSCLC patients who have received chemotherapy followed by a checkpoint inhibitor. The Phase 3 clinical trial is comparing the treatmentcombination of patientssitravatinib plus nivolumab randomized to docetaxel. The statistical design of the Phase 3 clinical trial includes an interim analysis of overall survival that we believe, if positive, could support an NDA submission seeking full approval.

In January 2019, we announced a clinical trial collaboration with NSCLC.BMS in connection with the aforementioned Phase 3 clinical trial. Under the terms of the collaboration, we are sponsoring and funding the clinical trial and BMS is providing nivolumab at no cost. We maintain global development and commercial rights to sitravatinib outside of certain Asian territories and Australia and New Zealand, where we have partnered with BeiGene, and we are free to develop the program in combination with other agents.

Two additional candidates are in pre-clinical development. The first is a mutant-selective KRAS inhibitor program which is advancing to candidate selection phase. Prototype inhibitors have demonstrated marked tumor regression in KRAS mutant tumor models and an IND candidate selection is anticipated by the end of 2017. The second is a highly-potent LSD1 inhibitor with potential for rapid clinical proof-of-concept in small cell lung cancer or acute myeloid leukemia. We plan to identify additional drug development opportunities by leveraging our deep scientific understanding of molecular drug targets and mechanisms of resistance and potentially in-licensing or internally discovering promising, early-stage novel drug product candidates.


We were incorporated under the laws of the State of Delaware on April 29, 2013 as Mirati Therapeutics, Inc. and our corporate headquarters is locatedalso have several Phase 2 clinical trials in San Diego, California.

Program Updates
Single Agent Programs

Our single agent clinical programswhich we are focused on select populations of patientsevaluating sitravatinib in combination with a variety of solid tumors but with a primary focus onnivolumab in patients with NSCLC, which accounts for 80 to 85%urothelial carcinoma or other cancers who have experienced documented disease progression following prior treatment with chemotherapy and/or a checkpoint inhibitor. On September 20, 2021, we announced results from a post hoc exploratory analysis of all lung cancer diagnoses. We believe there remains a significant unmet need and commercial opportunity for novel targeted agents that improve patient outcomes.

Glesatinib

We are enrolling patients in our registration-enablingthe Phase 2 NSCLC clinical trial (the "AMETHYST Trial"), which is evaluating single agent glesatinib for the treatment of NSCLCstudy, MRTX-500, in patients with MET driver alterations in two cohorts: patientsnonsquamous NSCLC with MET gene amplifications and patients with MET Exon 14 deletions. We reported preliminaryprior clinical data for both cohorts in January 2017. We expect to provide a program update for the AMETHYST trial by the end of 2017. We expect that this data, in addition to our assessment of the competitive landscape, will determine our development plans for this program going forward.

Sitravatinib

We are enrolling patients in our multi-center Phase 1b expansion clinical trial (the "CITRINE Trial"), which is evaluating single agent sitravatinib for the treatment of NSCLC patients with RET, CHR4q12 and CBL genetic alterations. We reported early databenefit from this clinical trial in January 2017 and in September 2017 we presented a case study at the IASLC 2017 Chicago Multidisciplinary Symposium in Thoracic Oncology (“the IASLC 2017 Symposium”) of an NSCLC patient with a CBL inactivating mutation. The case was the first evaluable NSCLC patient harboring a CBL mutation treated in the ongoing Phase 1b study of sitravatinib as a single agent. The confirmed partial response is the first example of clinical activity for sitravatinib in a patient with a CBL mutation. Inactivating mutations in CBL occur in approximately 1.5% of NSCLC patients and currently represent an unmet medical need.

Immuno-oncology Combination Programs

Sitravatinib plus nivolumab

We are enrolling patients in a Phase 2 NSCLC clinical trial evaluating sitravatinib, dosed once per day at 120 milligrams, in combination with full dose nivolumab, a PD-1 checkpoint inhibitor approved for the treatment of patients with NSCLC. This clinical trial is designed to assess the potential of sitravatinib to inhibit several important immunosuppressive pathways that may be important in overcoming resistance to checkpoint inhibitor therapy and is enrollingwhere anti-PD-(L)1 was the most recent line of therapy (n=68) and a median follow-up of 33.6 months. The median overall survival was 14.9 months (95% CI: 9.3, 21.1), with 56% and 32% of these patients who have relapsed after treatmentalive at one year and two years, respectively. The ORR was 18%, with 3% of patients achieving a checkpoint inhibitor, as well as checkpoint inhibitor-naïve patients. complete response and 15% of patients achieving a PR. The median DOR was 12.8 months.

Sitravatinib Development in Collaboration with BeiGene

In September 2017,January 2018, we presentedentered into a case study atCollaboration and License Agreement with BeiGene (the “BeiGene Agreement”). Under the IASLC 2017 Symposium which provided a preliminaryBeiGene Agreement, we granted BeiGene an exclusive license to develop, manufacture and commercialize sitravatinib in Asia (excluding Japan and certain other countries), Australia and New Zealand (the “BeiGene Licensed Territory”), and we retained exclusive rights for the development, manufacturing and commercialization of sitravatinib outside the BeiGene Licensed Territory.

In November 2018, we dosed the first patient under the BeiGene Agreement to assess the safety and efficacy update for this clinical trial. In the efficacy data presented, three patients experienced a confirmed partial response outtolerability, pharmacokinetics and preliminary anti-tumor activity of 11 evaluable patients. Early safety data indicated an acceptable profile and manageable adverse events. Based on the data presented, the pre-defined criteria for expansion was met and the next stage will enroll a cumulative total of 34 patients.

Mocetinostat plus durvalumab

We are collaborating with MedImmune/Astra Zeneca on a Phase 2 NSCLC clinical trial combining mocetinostat and durvalumab, MedImmune's PD-L1 inhibitor for the treatment of patients with NSCLC. In this clinical trial, mocetinostat is being dosed three times per week at 70 milligramssitravatinib in combination with full dose durvalumab.BeiGene’s investigational anti-PD-1 antibody, tislelizumab, in patients with advanced solid tumors. BeiGene’s clinical trials will evaluate the combination of sitravatinib and tislelizumab in patients with solid tumors including NSCLC, renal cell carcinoma, hepatocellular cancer, gastric cancer and ovarian cancer.

MRTX1719, a synthetic lethal MTA cooperative PRMT5 inhibitor

MRTX1719, our lead synthetic lethal MTA cooperative PRMT5 inhibitor is an investigational, selective, potent and orally available inhibitor targeting the PRMT5/MTA complex in methylthioadenosine phosphorylase (MTAP)-deleted cancers and is in Phase 1/2 clinical development. The clinical trialMTAP deletion is enrolling patients who have relapsed after treatmentpresent in approximately 10 percent of all cancers and is the most frequently observed gene deletion event (MTAP/CDKN2A) across several cancer types. Cancers with an MTAP deletion, such as pancreatic, lung, and bladder cancers, are associated with a checkpoint inhibitor, as well as checkpoint inhibitor-naïve patients.  We expectpoor prognosis, representing a significant unmet medical need.

In preclinical studies, MRTX1719 has demonstrated a greater than 70-fold selectivity for MTAP-deleted cells relative to normal cells and demonstrated near complete and sustained inhibition of PRMT5 in tumor xenografts resulting in significant tumor growth inhibition or tumor regression in MTAP-deleted tumor models. The ability to target the PRMT5/MTA complex provides an opportunity to selectively target tumor cells harboring the MTAP gene deletion which exhibit an abnormally high level of MTA (methylthioadenosine) compared with normal cells. This is anticipated to provide an update on both immuno-oncology combination clinical trials in late 2017.

increased therapeutic index relative to first generation PRMT5 inhibitors that do not specifically target the PRMT5/MTA complex. In October 2017,the first quarter of 2022, we announced that we have been included in the SU2C Catalyst® program,initiated a cutting-edge research initiative led by Stand up to Cancer (“SU2C”) designed to bring innovative cancer treatments to patients quickly through novel collaborations between industry and academia. The Phase 1/1b clinical2 multiple expansion cohort trial sponsored by Memorial Sloan Kettering Cancer Center, is designed to evaluate MRTX1719 in patients with advanced, unresectable or metastatic solid tumor malignancy with homozygous deletion of the potential of epigenetic agents to improve patient responses to immunotherapy in NSCLC which will combine mocetinostat, guadecitabine, a DNA methyltransferase inhibitor from Astex Pharmaceuticals, Inc., and pembrolizumab, a PD-1 checkpoint inhibitor from Merck KGaA (known as MDS outside the United States and Canada). The clinical trial enrolled its first patient in August 2017.MTAP gene.


Liquidity Overview
In January 2017, we completed a public offering of our common stock and pre-funded common stock warrants that generated net proceeds of $66.8 million.  At September 30, 2017, we had $75.0 million of cash, cash equivalents and short-term investments compared to $56.7 million at December 31, 2016. We have not generated any revenue from product sales. To date, we have funded our operations primarily through the sale of our common stock and through up-front payments, research funding and milestone payments under previous collaborative arrangements. To fund future operations, we will likely need to raise additional capital as discussed more fully below under the heading “Liquidity and Capital Resources.”

Research and development expenses for the three months ended March 31, 2022 were $131.0 million compared to $104.1 million for the three months ended March 31, 2021. The increase of $26.9 million primarily relates to increases in share-based compensation expense of $11.7 million, salaries and other employee related expense of $9.3 million, third-party research and development expense of $3.6 million, and other research and development expense of $2.3 million. The increase in share-based compensation of $11.7 million, and salaries and other employee related expense of $9.3 million is primarily due to an increase in the number of research and development employees during the three months ended March 31, 2022, compared to the same period in 2021. The increase in third-party research and development expense primarily relates to an increase in expenses associated with development of adagrasib of $1.6 million, MRTX1719 of $1.7 million, preclinical and early discovery program of $1.6 million and sitravatinib of $0.7 million, offset by a decrease in MRTX1133 of $2.0 million. The increase in expenses associated with adagrasib relates to the ongoing clinical trials, which include Phase 1/2, Phase 2 and Phase 3 clinical trials. The costs are comprised largely of manufacturing expenses, including manufacturing costs related to registrational manufacturing batches, CRO fees and other clinical trial-related expenses. The increase in expenses associated with MRTX1719 is because the compound entered the clinic during the three months ended March 31, 2022; the costs are comprised largely of manufacturing expenses and CRO fees. MRTX1719 was designated as a clinical candidate during the second quarter of 2021; prior to this designation, the costs were classified as preclinical and early discovery costs. The increase in preclinical and early discovery costs is primarily due to increased contracted research and development services to support our early discovery efforts. The increase in expenses associated with the development of sitravatinib relates to increased investigator payment expenses and CRO fees to support the expansion of existing sitravatinib clinical trials. The decrease in expense when theassociated with MRTX1133 is primarily due to lower manufacturing expenses, toxicology and contract research and development services. The increase in other research and development costs of $2.3 million is primarily due to increases in professional services have been performed orexpenses, medical communications, travel and software license.


when the goods have been received.
At this time, due to the risks inherent in the clinical development process and the early stage of our product development programs we are unable to estimate with any certainty the costs we will incur in the continued development of adagrasib and sitravatinib, MRTX1719, MRTX1133 and any of our glesatinib, sitravatinib, mocetinostatother preclinical and preclinicalearly discovery programs. The process of conducting clinical trials necessary to obtain regulatory approval and manufacturing scale-up to support expanded development and potential future commercialization is costly and time consuming. Any failure by us or delay in completing clinical trials, manufacturing scale up or in obtaining regulatory approvals could lead to increased research and development expense and, in turn, have a material adverse effect on our results of operations. We expect that our research and development expenses may increase if we are successful in advancing adagrasib, sitravatinib, MRTX1719 and MRTX1133 or any of our glesatinib, sitravatinib, mocetinostat clinical development programs or ourother preclinical programs including the KRAS inhibitor program, into more advanced stages of clinical development.

Our research and development efforts during the three and nine months ended September 30, 2017 and 2016 were focused primarily on our oncology programs, including our two lead kinase programs, glesatinib and sitravatinib, our HDAC inhibitor program, mocetinostat, and our preclinical KRAS inhibitor program. The following table summarizes our research and development expenses (in thousands):

Research and development expenses for the three months ended September 30, 2017 were $13.5 million compared to $16.1 million during the three months ended September 30, 2016. The decrease
Table of $2.6 million primarily relates to decreases in third-party development expense of $1.7 million due predominantly to reduced manufacturing expenses for glesatinib, partially offset by increased expenses for ongoing clinical trials of sitravainib and continued investment in our preclinical KRAS program. Additionally, there was a decrease in share-based compensation expense of $0.8 million that is due to a decrease in the fair value of stock options and the resulting share-based compensation expense.Contents

Research and development expenses for the nine months ended September 30, 2017 were $42.8 million compared to $52.5 million during the nine months ended September 30, 2016. The decrease of $9.7 million primarily relates to a decrease in third-party development expense of $7.8 million and a decrease of share-based compensation expense of $1.8 million. The decrease in third-party research and development expense is due to the same factors that influenced similar fluctuations for the three months ended September 30, 2017 discussed above, and the absence of expense associated with a one-time license fee incurred during 2016 related to an early stage discovery project. The decrease in share-based compensation expense is due to the same factors that influenced a similar fluctuation for the three months ended September 30, 2017.

General and administrative expenses


General and administrative expenses consist primarily of salaries and related benefits, including share-based compensation, related to our executive, finance, business development, legal, commercial and support functions. Other general and administrative expenses include professional fees for auditing, tax, consulting and taxpatent-related services, rent and utilities and insurance.



General and administrative expenses for the three months ended September 30, 2017March 31, 2022 and 20162021 were $3.1$54.0 million and $3.5$28.4 million, respectively, a decreaserepresenting an increase of $0.4$25.6 million.
General The increase in expense for the three months ended March 31, 2022 is primarily due to an increase in salaries and other employee related expense of $10.0 million, an increase in professional services expense of $9.6 million, an increase in share-based compensation expense of $6.5 million, and an increase in insurance, rent and other facilities-related costs and other expense of $2.5 million. The increase in salaries and other employee related expense, and share-based compensation expense is primarily due to an increase in the number of general and administrative expenses foremployees during the ninethree months ended September 30, 2017March 31, 2022 compared to the same period in 2016 were $10.5 million2021, and $11.4 million, respectively, a decrease of $0.9 million.is largely driven by commercial readiness activities. The decrease for both periodsincrease in professional services expense is primarily due to an increase in commercial costs as we prepare for a decreasepotential product launch and includes market research and professional consulting fees. The increase in share-based compensationfacilities, insurance and other expense whichis primarily due to increased software licensing costs and expensed equipment due to increased headcount, as well as increased director and officer liability insurance expense.

Other Expense, Net

Other expense, net for the three months ended March 31, 2022 was expense of $4.2 million, compared to expense of $3.3 million for the same period in 2021. The increase in expense is due to a lowerdecline in the fair value of stock options awarded and resulting share-based compensation expense.our long-term investment in ORIC which was acquired in 2020 in connection with the ORIC Agreement.


Liquidity and Capital Resources

As of March 31, 2022, we had $1.3 billion of cash, cash equivalents and short-term investments compared to $1.5 billion as of December 31, 2021. In January 2017,November 2021, we completed a public offering of our common stock and pre-funded common stock warrants that generated net proceeds of $66.8$474.7 million. At September 30, 2017,In July 2021, we had $75.0received net proceeds of $63.4 million for the up-front fee in connection with the Zai Agreement. In July 2021, we entered into an amended and restated sales agreement pursuant to which we may, from time to time, sell shares of cash, cash equivalentsour common stock having an aggregate offering price of up to $500.0 million; as of March 31, 2022, no shares have been sold in connection with this amended and short-term investments compared to $56.7 million at December 31, 2016. restated sales agreement.Based on our current and anticipated level of operations, we believe that our cash, cash equivalents and short-term investments will be sufficient to meet our anticipated obligations for at least one year from the date ofthat this quarterly reportQuarterly Report on Form 10-Q is filed with the SEC.

To date, we have funded our operations primarily through the sale of our common stock, pre-funded warrants to purchase our common stock and, through up-front payments, research funding and milestone payments under previous collaborative arrangements. Since inception, we have primarily devoted our resources to ourfunding research and development programs, including discovery research, preclinical and clinical development activities. To fund future operations, we will likely need to raise additional capital. The amount and timing of future funding requirements will depend on many factors, including the timing and results of our ongoing development efforts, the potential expansion of our current development programs, potential new development programs and related general and administrative support. We anticipate that we will seek to fund our operations through public or private equity or debt financings or other sources, such as potential collaboration agreements. We cannot make assurances that anticipated additional financing will be available to us on favorable terms, or at all. Although we have previously been successful in obtaining financing through our equity securities offerings, there can be no assurance that we will be able to do so in the future. As a result of the COVID-19 pandemic and actions taken to slow its spread, the global credit and financial markets have experienced extreme volatility, including in liquidity and credit availability, declines in consumer confidence, declines in economic growth, increases in unemployment rates and uncertainty about economic stability. There can be no assurance that deterioration in credit and financial markets and confidence in economic conditions will not occur. If equity and credit markets deteriorate, it may make any necessary debt or equity financing more difficult to obtain, more costly and/or more dilutive.

During the three and nine months ended September 30, 2017, we did not have any off-balance sheet arrangements (as defined by applicable SEC regulations) that are reasonably likely to have a current or future material effect on our financial condition, results of operations, liquidity, capital expenditures or capital resources.

Recent Accounting Pronouncements

Occasionally, new accounting standards are issued or proposed by the Financial Accounting Standards Board, or other standard-setting bodies that we adopt by the effective date specified within the standard. Unless otherwise discussed, standards that do not require adoption until a future date are not expected to have a material impact on our financial statements upon adoption.

ITEM 3.
Quantitative and Qualitative Disclosures about Market Risk


Interest Rate Risk


Some of our short-term investments have market risk in that a change in prevailing interest rates may cause the fair value of the principal amount of the investment to fluctuate. Financial instruments that potentially subject us to significant concentrations of credit risk consist primarily of cash, cash equivalents and short-term investments. We invest our excess cash primarily in commercial paper and debt instruments of financial institutions, corporations, U.S. government-sponsored agencies and the U.S. Treasury. We mitigate credit risk by maintaining a well-diversified portfolio and limiting the amount of investment exposure as to institution, maturity and investment type. We invest our excess cash in accordance with our investment policy.


Because of the short-term maturities of our cash equivalents and short-term investments, we do not believe that an increase in market rates would have any significant impact on the realized value of our investments. If a 1%10% change in interest rates were to have occurred on September 30, 2017,March 31, 2022, this change would not have had a material effect on the fair value of our investment portfolio as of that date.


Effects of Inflation


We do not believe that inflation and changing prices had a significant impact on our results of operations for any periods presented herein.

Item 1A.    Risk Factors


You should carefully consider carefully the following information about the risks described below, together with the other information contained in this Quarterly Report and in our other public filings in evaluating our business. The risk factors set forth below with an asterisk (*) next to the title contain changes to the description of the risk factors associated with our business previously disclosed in Item 1A of our Annual Report on Form 10-K for the year ended December 31, 2016.2021. Additional risks and uncertainties that we are unaware of may also become important factors that affect us. If any of the following risks actually occurs, our business, financial condition, results of operations and future growth prospects would likely be materially and adversely affected. In these circumstances, the market price of our common stock would likely decline.


Summary of Risk Factors

We face a number of risks and uncertainties related to our business and our securities, many of which are beyond our control. Some of our principal risks related to our business include the following:

Risks Relating to our Business and Industry
Our research and development programs and product candidates are in development. As a result, we are unable to predict if or when we will successfully develop or commercialize our product candidates.
All of our product candidates are subject to extensive regulation, which can be costly and time consuming, cause delays or prevent approval of such product candidates for commercialization
The successful commercialization of our product candidates, if approved, will depend on achieving market acceptance and we may not be able to gain sufficient acceptance to generate significant revenue.
The COVID-19 pandemic could adversely impact our business including our ongoing and planned clinical trials and preclinical research.
We rely upon third-party contractors and service providers for the execution of some aspects of our development programs. Failure of these collaborators to provide services of a suitable quality and within acceptable timeframes may cause the delay or failure of our development programs.
Competition in our targeted market area is intense and this field is characterized by rapid technological change. Therefore, developments by competitors may substantially alter the predicted market or render our product candidates uncompetitive
Our product candidates may cause undesirable side effects or have other properties that could delay or prevent their regulatory approval, limit the commercial profile of an approved product label, or result in significant negative consequences following marketing approval, if any.
We are subject to competition for our skilled personnel and may experience challenges in identifying and retaining key personnel that could impair our ability to conduct our operations effectively.

Risks Related to our Financial Position and Capital Requirements

*    We will require additional financing and may be unable to raise sufficient capital, which could lead us to delay, reduce or abandon development programs or commercialization.


Our operations have consumed substantial amounts of cash since inception. Our research and development expenses were $13.5 million and $16.1 millionRisks Related to our Intellectual Property
We may not obtain adequate protection for the three months ended September 30, 2017 and 2016, respectively, and $42.8 million and $52.5 million for the nine months ended September 30, 2017 and 2016, respectively. In January 2017, we completed a public offering of our common stock and pre-funded common stock warrants that generated net proceeds of $66.8 million. We will require substantial additional capital to pursue additional clinical development for our lead clinical programs, including conducting late-stage clinical trials, manufacturing clinical supplies and potentially developing other assets in our pipeline, and, if we are successful, to commercialize any of our current product candidates. If the U.S. Food and Drug Administration ("FDA") or any foreign regulatory agency, such as the European Medicines Agency ("EMA") requires that we perform studies or trials in addition to those that we currently anticipate with respect to the development of our product candidates or repeat studies or trials,through patents and other intellectual property rights and as such, our expenses would further increase beyond what we currently expect. We may not be able to adequately finance our development programs, which could limit our ability to move our programs forwardcompetitive advantage in a timely and satisfactory manner or require us to abandon the programs, any of which would harm our business, financial condition and results of operations. Because successful development of our product candidates is uncertain, we are unable to estimate the actual funds we will require to complete research and development and commercialize our product candidates.

If we are unable to obtain funding from equity offerings or debt financings on a timely basis, wemarketplace may be required to (1) seek collaborators for one or more of our product candidates at an earlier stage than otherwise would be desirable or on terms that are less favorable than might otherwise be available; (2) relinquish or license on unfavorable terms our rights to technologies or product candidates that we otherwise would seek to develop or commercialize ourselves; or (3) significantly curtail one or more of our research or development programs or cease operations altogether.compromised.
We are a clinical-stage company with no approved products and no historical product revenue. Consequently, we expect that our financial and operating results will vary significantly from period to period.

Other factors set forth herein.
We are a clinical-stage company that has incurred losses since its inception and expect to continue to incur substantial losses in the foreseeable future. Biopharmaceutical product development is a highly speculative undertaking and involves a substantial degree of uncertainty.

Our actual financial condition and operating results have varied significantly in the past and are expected to continue to fluctuate significantly from quarter-to-quarter or year-to-year due to a variety of factors, many of which are beyond our control. Factors relating to our business that may contribute to these fluctuations include:

the success of our clinical trials through all phases of clinical development;

delays in the commencement, enrollment and timing of clinical trials;


our ability to secure and maintain collaborations, licensing or other arrangements for the future development and/or commercialization of our product candidates, as well as the terms of those arrangements;

our ability to obtain, as well as the timeliness of obtaining, additional funding to develop our product candidates;

the results of clinical trials or marketing applications for product candidates that may compete with our product candidates;

competition from existing products or new products that may receive marketing approval;

potential side effects of our product candidates that could delay or prevent approval or cause an approved drug to be taken off the market;

any delays in regulatory review and approval of our clinical development plans or product candidates;

our ability to identify and develop additional product candidates;

the ability of patients or healthcare providers to obtain coverage or sufficient reimbursement for our products;

our ability, and the ability of third parties such as Clinical Research Organizations ("CROs") to adhere to clinical study and other regulatory requirements;

the ability of third-party manufacturers to manufacture our product candidates and key ingredients needed to conduct clinical trials and, if approved, successfully commercialize our products;

the costs to us, and our ability as well as the ability of any third-party collaborators, to obtain, maintain and protect our intellectual property rights;

costs related to and outcomes of potential intellectual property litigation;

our ability to adequately support future growth;

our ability to attract and retain key personnel to manage our business effectively; and

our ability to build our finance infrastructure and, to the extent required, improve our accounting systems and controls.

Accordingly, the likelihood of our success must be evaluated in light of many potential challenges and variables associated with a clinical-stage company, many of which are outside of our control, and past operating or financial results should not be relied on as an indication of future results. Fluctuations in our operating and financial results could cause our share price to decline. It is possible that in some future periods, our operating results will be above or below the expectations of securities analysts or investors, which could also cause our share price to decline.

*We have incurred significant losses since our inception and anticipate that we will continue to incur significant losses for the foreseeable future. We have never generated any revenue from product sales and may never be profitable.

We have derived limited revenue from our research and licensing agreements which has not been sufficient to cover the substantial expenses we have incurred in our efforts to develop our product candidates. Consequently, we have accumulated net losses since inception in 1995. Our net loss for the three and nine months ended September 30, 2017 and 2016 was $16.4 million and $19.4 million, respectively, and $52.5 million and $63.4 million, respectively. As of September 30, 2017, we had an accumulated deficit of $442.7 million. Our prior losses, combined with expected future losses, have had and will continue to have an adverse effect on our stockholders' equity and working capital. Such losses are expected to increase in the future as we continue the development of our product candidates and seek regulatory approval and commercialization for our product candidates. We are unable to predict the extent of any future losses or when we will become profitable, if ever. Even if we do achieve profitability, we may not be able to sustain or increase profitability on an ongoing basis.

We do not anticipate generating revenue from sales of products for the foreseeable future, if ever. If any of our product candidates fail in clinical trials or do not gain regulatory approval, or if any of our product candidates, if approved, fail to achieve market acceptance, we may never become profitable. If one or more of our product candidates is approved for commercial sale and we retain commercial rights, we anticipate incurring significant costs associated with commercializing any such approved product candidate. Therefore, even if we are able to generate revenue from the sale of any approved product, we may never become

profitable. Even if we achieve profitability in the future, we may not be able to sustain profitability in subsequent periods. Our ability to generate future revenue from product sales depends heavily on our success in:

completing development and clinical trial programs for our product candidates;

entering into collaboration and license agreements;

seeking and obtaining marketing approvals for any product candidates that successfully complete clinical trials;

establishing and maintaining supply and manufacturing relationships with third parties;

successfully commercializing any product candidates for which marketing approval is obtained; and

successfully establishing a sales force and marketing and distribution infrastructure.

Raising additional funds through debt or equity financing will be dilutive and raising funds through licensing agreements may be dilutive, restrict operations or relinquish proprietary rights.

To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of those securities could result in substantial dilution for our current stockholders and the terms may include liquidation or other preferences that adversely affect the rights of our current stockholders. Existing stockholders may not agree with our financing plans or the terms of such financings. Moreover, the incurrence of debt financing could result in a substantial portion of our operating cash flow being dedicated to the payment of principal and interest on such indebtedness and could impose restrictions on our operations. In addition, if we raise additional funds through collaboration and licensing arrangements, it may be necessary to relinquish potentially valuable rights to our products or proprietary technologies, or to grant licenses on terms that are not favorable to us. Additional funding may not be available to us on acceptable terms, or at all.

As a public company in the United States, we incur significant legal and financial compliance costs and we are subject to the Sarbanes-Oxley Act. We can provide no assurance that we will, at all times, in the future be able to report that our internal controls over financial reporting are effective.

Companies that file reports with the Securities and Exchange Commission ("SEC"), including us, are subject to the requirements of Section 404 of the Sarbanes-Oxley Act of 2002. Section 404 requires management to establish and maintain a system of internal control over financial reporting, and annual reports on Form 10-K filed under the Securities Exchange Act of 1934, as amended ("the Exchange Act"), must contain a report from management assessing the effectiveness of a company’s internal control over financial reporting. Ensuring that we have adequate internal financial and accounting controls and procedures in place to produce accurate financial statements on a timely basis remains a costly and time-consuming effort that needs to be re-evaluated frequently. Failure on our part to have effective internal financial and accounting controls would cause our financial reporting to be unreliable, could have a material adverse effect on our business, operating results, and financial condition, and could cause our stock price to decline as a result.

As an “emerging growth company” (as defined in the JOBS Act), we are not required to comply with Section 404(b) which requires attestation from our external auditors on our internal control over financial reporting. We are subject to Section 404(a), which requires management to provide a report regarding the effectiveness of internal controls. We are required to review all of our control processes to align them to the Section 404 requirements. Failure to provide assurance that our financial controls are effective could lead to lack of confidence by investors which could cause our stock price to decline. When we are no longer an “emerging growth company” (as defined in the Exchange Act or the Securities Act of 1933, as amended (the "Securities Act"), our independent registered public accounting firm will be required to attest to the effectiveness of our internal control over financial reporting. The rules governing the standards that must be met for management to assess our internal control over financial reporting are complex and require significant documentation, testing and possible remediation. To continue complying with the requirements of being a reporting company under the Exchange Act, we may need to further upgrade our systems, including information technology, implement additional financial and management controls, reporting systems and procedures, and hire additional accounting and finance staff.

In addition, our independent registered public accounting firm has never performed an evaluation of our internal control over financial reporting in accordance with the provisions of the Sarbanes-Oxley Act because no such evaluation has been required. Had our independent registered public accounting firm performed an evaluation of our internal control over financial reporting in accordance with the provisions of the Sarbanes-Oxley Act, significant deficiencies or material weaknesses may have been identified. If we identify any significant deficiencies or material weaknesses that may exist or are unable to successfully remediate any

significant deficiency or material weakness in our internal control over financial reporting, the accuracy and timing of our financial reporting may be adversely affected, we may be unable to maintain compliance with securities law requirements regarding timely filing of periodic reports in addition to applicable stock exchange listing requirements, investors may lose confidence in our financial reporting, and our stock price may decline as a result.

Furthermore, shareholder activism, the current political environment and the current high level of government intervention and regulatory reform may lead to substantial new regulations and disclosure obligations, which may lead to additional compliance costs and impact the manner in which we operate our business in ways we cannot currently anticipate. Our management and other personnel will need to devote a substantial amount of time to these compliance initiatives. Moreover, any new regulations or disclosure obligations may increase our legal and financial compliance costs and will make some activities more time-consuming and costly.

We are an emerging growth company and we cannot be certain if the reduced disclosure requirements applicable to emerging growth companies will make our common stock less attractive to investors.

We are an emerging growth company. Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards until such time as those standards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and, therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

For as long as we continue to be an emerging growth company, we intend to take advantage of certain other exemptions from various reporting requirements that are applicable to other public companies including, but not limited to, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, exemptions from the requirements of holding a nonbinding advisory stockholder vote on executive compensation and any golden parachute payments not previously approved, exemption from the requirement of auditor attestation in the assessment of our internal control over financial reporting and exemption from any requirement that may be adopted by the Public Company Accounting Oversight Board. If we do continue to be an emerging growth company, the information that we provide stockholders may be different than what is available with respect to other public companies. We cannot predict if investors will find our common stock less attractive because we rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less-active trading market for our common stock and our stock price may be more volatile.

We will remain an emerging growth company until the earliest of (1) the end of the fiscal year in which the market value of our common stock that is held by non-affiliates exceeds $700 million as of the end of the second fiscal quarter, (2) the end of the fiscal year in which we have total annual gross revenue of $1 billion or more during such fiscal year, (3) the date on which we issue more than $1 billion in non-convertible debt in a three-year period, or (4) December 31, 2018.

Decreased disclosures in our SEC filings due to our status as an emerging growth company may make it harder for investors to analyze our results of operations and financial prospects.


Risks RelatingRelated to Our Business and Industry


Our research and development programs and product candidates are at an early stage ofin development. As a result, we are unable to predict if or when we will successfully develop or commercialize our product candidates.


Our clinical-stage product candidates as well as our other pipeline assets are at an early stage of development and will require significant further investment and regulatory approvals prior to commercialization. We currently have no product candidates beyondAdagrasib is in Phase 3 and Phase 1/2 clinical trials. Glesatinibtrials, sitravatinib is currently in a Phase 3
26

clinical trial, and Phase 1/2 clinical trial, mocetinostattrials, MRTX1719 is currently in a Phase 2 combination1 clinical trial, sitravatiniband MRTX1133 is in Phase 1b single agent and Phase 2 combination clinical trials and we have a KRAS inhibitor preclinical program.development. We recently submitted an NDA to the FDA to adagrasib. Each of our product candidates will require the selection of suitable patients for our clinical trials and additional clinical development, management of clinical, preclinical and manufacturing activities, obtaining regulatory approval, obtaining manufacturing supply, buildingcontinued build out of a commercial organization, substantial investment and significant marketing efforts before we generate any revenues from product sales. We are not permitted to market or promote any of our product candidates before we receive regulatory approval from the FDA or comparable foreign regulatory authorities, and we may never receive such regulatory approval for any of our product candidates. The treatment of cancer is a rapidly evolving field and will continue to evolve. By such time, if ever, as we may receive necessary regulatory approvals for our product candidates, the standard of care for the treatment of cancers may have evolved such that it would be necessary to modify our plans for full approval and commercial acceptance of our products may be limited by a change in the standard of care. In addition, some of our product development programs contemplate the development of companion diagnostics. Companion diagnostics are subject to regulation as medical

devices and we or our future collaborators may be required to obtain marketing approval for accompanying companion diagnostics before we may commercialize our product candidates.


Even if we obtain the required financing or establish a collaboration to enable us to conduct late-stage clinical development of our product candidates and pipeline assets, we cannot be certain that such clinical development would be successful, or that we will obtain regulatory approval or be able to successfully commercialize any of our product candidates and generate revenue. Success in preclinical testing and early clinical trials does not ensure that later clinical trials will be successful, and the clinical trial process may fail to demonstrate that our product candidates are safe and effective for their proposed uses. Any such failure could cause us to abandon further development of any one or more of our product candidates and may delay development of other product candidates. Product candidates in later stages of clinical trials may fail to show the desired safety and efficacy traits despite having progressed through preclinical studies and initial clinical trials. Any delay in, or termination of, our clinical trials will delay and possibly preclude the submission of any new drug applications ("NDAs"(“NDA”) with the FDA and, ultimately, our ability to commercialize our product candidates and generate product revenue.


We recently submitted an NDA to the FDA. We, however, have not previously submitted an NDA to the FDA, or similar drug approval filings to comparable foreign authorities, for any product candidate, and we cannot be certain that any of our product candidates will receive regulatory approval. Further, our product candidates may not receive regulatory approval even if they are successful in clinical trials. If we do not receive regulatory approvals for our product candidates, we may not be able to continue our operations. Even if we successfully obtain regulatory approvals to market one or more of our product candidates, our revenues will be dependent, in part, upon our or ourcurrent collaborators’ and future collaborators’ ability to obtain regulatory approval for the companion diagnostics to be used with our product candidates, if required, and upon the size of the markets in the territories for which we gain regulatory approval and have commercial rights. If the markets for patient subsets that we are targeting are not as significant as we estimate, we may not generate significant revenues from sales of such products, if approved.


Further, even if any product candidate we develop was to receive marketing approval or be commercialized for use in combination with other existing therapies, we would continue to bear the risks that the FDA or similar foreign regulatory authorities could revoke approval of the therapy used in combination with our product candidate or that safety, efficacy, manufacturing or supply issues could arise with these existing therapies.

All of our product candidates are subject to extensive regulation, which can be costly and time consuming, cause delays or prevent approval of such product candidates for commercialization.


The clinical development of product candidates is subject to extensive regulation by the FDA in the United States and by comparable regulatory authorities in foreign markets. Product development is a very lengthy and expensive process, and its outcome is inherently uncertain. The product development timeline can vary significantly based upon the product candidate’s novelty and complexity.complexity, and the applicable regulatory authority. For example, we are pursuing an expansion strategy to bring our leading product candidate to countries within the European Economic Area (“EEA”) and the United Kingdom (“UK”). The regulatory approval in other countries may include all the risks associated with FDA approval as well as additional, presently unanticipated, risks. Regulations are subject to change and regulatory agencies have significant discretion in the approval process.


Numerous statutes and regulations govern human testing and the manufacture and sale of human therapeutic products in the United States, Europe and other countries and regions where we intend to market our products. Such legislation and regulation bears upon, among other things, the approval of trial protocols and human testing, the approval of manufacturing facilities, safety of the product candidates, testing procedures and controlled research, review and approval of manufacturing,
27

preclinical and clinical data prior to marketing approval including adherence to good manufacturing practices ("GMP"(“GMP”) during production and storage as well as regulation of marketing activities including advertising and labeling.


In order to obtain regulatory approval, including an NDA or marketing authorization application, for the commercial sale of any of our product candidates in the United States, EEA and other foreign market, we must demonstrate through preclinical studies and clinical trials, as well as extensive information regarding chemistry, manufacturing and controls (“CMC”), that the potential product is safe and effective for use in humans for each target indication. The failure to adequately demonstrate the safety and efficacy of a product under development could delay or prevent regulatory approval of our product candidates. Regulatory approval in one country does not ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval in one country may negatively impact the regulatory process in others.


No assurance can be given that current regulations relating to regulatory approval will not change or become more stringent in the United States or foreign markets. Regulatory agencies may also require that additional trials be run in order to provide additional information regarding the safety or efficacy of any drug candidates for which we seek regulatory approval.approval or require additional administrative review periods, including obtaining reimbursement and pricing approval in select markets. Moreover, any regulatory approval of a drug which is eventually obtained may entail limitations on the indicated uses for which that drug may be marketed. Furthermore, product approvals may be withdrawn or limited in some way if problems occur following initial marketing or if compliance with regulatory standards is not maintained. Regulatory agencies could become more risk averse to any side effects or set higher standards of safety and efficacy prior to reviewing or approving a product. This could result in a product not being approved. Any of the foregoing scenarios could materially harm the commercial prospects for our product candidates.


The successful commercialization of our product candidates, if approved, will depend on achieving market acceptance and we may not be able to gain sufficient acceptance to generate significant revenue.

Even if our product candidates are successfully developed and receive regulatory approval, they may not gain market acceptance among physicians, patients, healthcare payors such as private insurers or governments and other funding parties and the medical community. The degree of market acceptance for any of our products will depend on a number of factors, including:

demonstration of the clinical efficacy and safety of our products;

the prevalence and severity of any adverse side effects;

limitations or warnings contained in the product’s approved labeling;

cost-effectiveness and availability of acceptable pricing;

competitive product profile versus alternative treatment methods and the superiority of alternative treatment or therapeutics;

the effectiveness of marketing and distribution methods and support for the products; and

the availability of coverage and adequate reimbursement from third-party payors to the extent that our products receive regulatory approval.

Disease indications may be small subsets of a disease that could be parsed into smaller and smaller indications as different subsets of diseases are defined. This increasingly fine characterization of diseases could have negative consequences; including creating an approved indication that is so small as not to have a viable market for us. If future technology allows characterization of a disease in a way that is different from the characterization used for large pivotal studies, it may make those studies invalid or reduce their usefulness, and may require repeating all or a portion of the studies. Future technology may supply better prognostic ability which could reduce the portion of patients projected to need a new therapy. Even after being cleared by regulatory authorities, a product may later be shown to be unsafe or not to have its purported effect, thereby preventing its widespread use or requiring withdrawal from the market.

We may not be successful in establishing development and commercialization collaborations which could adversely affect, and potentially prohibit, our ability to develop our product candidates.


Because developing
28

Developing pharmaceutical products, conducting clinical trials, obtaining regulatory approval, establishing manufacturing capabilities and marketing approved products is expensive, and therefore we may seek to enter into additional collaborations with companies

that have more resources and experience in order to continue to develop and commercialize our product candidates. We also may be required due to financial or scientific constraints to enter into additional collaboration agreements to research and/or to develop and commercialize our product candidates. The establishment and realization of such collaborations may not be possible or may be problematic. There can be no assurance that we will be able to establish such additional collaborations on favorable terms, if at all, or that our current or future collaborative arrangements will be successful or maintained for any specific product candidate or indication. If we are unable to reach successful agreements with suitable collaboration partners for the ongoing development and commercialization of our product candidates, we may face increased costs, we may be forced to limit the scope and number of our product candidates we can commercially develop or the territories in which we commercialize such product candidates, and we may be unable to commercialize products or programs for which a suitable collaboration partner cannot be found. If we fail to achieve successful collaborations, our operating results and financial condition will be materially and adversely affected.


In addition, the terms of any collaboration agreements may place restrictions on our activities with respect to other products, including by limiting our ability to grant licenses or develop products with other third parties, or in different indications, diseases or geographical locations, or may place additional obligations on us with respect to development or commercialization of our product candidates. If we fail to comply with or breach any provision of a collaboration agreement, a collaborator may have the right to terminate, in whole or in part, such agreement or to seek damages.


Some of our collaboration agreements, including the BeiGene Agreement and Zai Agreement, are complex and involve sharing or division of ownership of certain data, know-how and intellectual property rights among the various parties. Accordingly, our collaborators could interpret certain provisions differently than we or our other collaborators which could lead to unexpected or inadvertent disputes with collaborators. In addition, these agreements might make additional collaborations, partnering or mergers and acquisitions difficult.


There is no assurance that a collaborator who is acquired by a third party would not attempt to change certain contract provisions that could negatively affect our collaboration. The acquiring company may also not accept the terms or assignment of our contracts and may seek to terminate the agreements. Any one of our collaborators could breach covenants, restrictions and/or sub-license agreement provisions leading us into disputes and potential breaches of our agreements with other partners.


If we or third parties are unable to successfully develop companion diagnostics for our product candidates, or experience significant delays in doing so, we may not achieve marketing approval or realize the full commercial potential of such product candidates.

A key part of our development strategy for each of glesatinib, sitravatinib and mocetinostat is to identify subsets of patients with specific types of tumors that express specific genetic markers. Identification of these patients will require the use and development of companion diagnostics. We expect that the FDA and comparable foreign regulatory authorities will require the regulatory approval of a companion diagnostic as a condition to approving our product candidates. We do not have experience or capabilities in developing or commercializing diagnostics and plan to rely in large part on third parties to perform these functions. We are developing companion diagnostics in collaboration with diagnostic platform providers including Foundation Medicine, Inc., Guardant Health and Qiagen Manchester Limited that we are using in the current Phase 2 trial of glesatinib, and that we anticipate using in later stage trials and commercialization, if approved. We do not currently have any long-term arrangements in place with any third party to develop or commercialize companion diagnostics for sitravatinib and mocetinostat product candidates.

Companion diagnostics are subject to regulation by the FDA and comparable foreign regulatory authorities as medical devices and will likely require separate regulatory approval prior to commercialization. If we or third parties are unable to successfully develop companion diagnostics for our product candidates, or experience delays in doing so:

the development of these product candidates may be delayed because it may be difficult to identify patients for enrollment in our clinical trials in a timely manner;

these product candidates may not receive marketing approval if their safe and effective use depends on a companion diagnostic; and

we may not realize the full commercial potential of these product candidates that receive marketing approval if, among other reasons, we are unable to appropriately identify patients or types of tumors with the specific genetic alterations targeted by these product candidates.

Even if our product candidates and any associated companion diagnostics are approved for marketing, the need for companion diagnostics may slow or limit adoption of our product candidates. Although we believe genetic testing is becoming more prevalent in the diagnosis and treatment of cancer, our product candidates may be perceived negatively compared to alternative

treatments that do not require the use of companion diagnostics, either due to the additional cost of the companion diagnostic or the need to complete additional procedures to identify genetic markers prior to administering our product candidates.

If any of these events were to occur, our business and growth prospects would be harmed, possibly materially.

We rely upon third-party contractors and service providers for the execution of some aspects of our development programs. Failure of these collaborators to provide services of a suitable quality and within acceptable timeframes may cause the delay or failure of our development programs.

We outsource certain functions, tests and services to CROs, medical institutions and collaborators and outsource manufacturing to collaborators and/or contract manufacturers, and we rely on third parties for quality assurance, clinical monitoring, clinical data management and regulatory expertise. In particular, we rely on CROs to run our clinical trials on our behalf and contract manufacturers to manufacture our product candidates. There is no assurance that such individuals or organizations will be able to provide the functions, tests, drug supply or services as agreed upon or to acceptable quality standards, and we could suffer significant delays in the development of our products or processes.

In some cases, there may be only one or few providers of such services, including clinical data management and manufacturing services. In addition, the cost of such services could increase significantly over time. We rely on third parties as mentioned above to enroll qualified patients and conduct, supervise and monitor our clinical trials. Our reliance on these third parties and collaborators for clinical development activities reduces our control over these activities, but does not relieve us of our regulatory responsibilities, including ensuring that our clinical trials are conducted in accordance with good clinical practices ("GCP") regulations and the investigational plan and protocols contained in the regulatory agency applications. In addition, these third parties may not complete activities on schedule or may not manufacture compounds under GMP conditions. Preclinical studies may not be performed or completed in accordance with good laboratory practices, or GLP, regulatory requirements or our trial design. If we or our CROs fail to comply with GCP regulations, the clinical data generated in our clinical trials may be deemed unreliable and the FDA, the EMA or comparable foreign regulatory authorities may require us to perform additional clinical trials before approving any marketing applications. If these third parties or collaborators do not successfully carry out their contractual duties or meet expected deadlines, obtaining regulatory approval for manufacturing and commercialization of our product candidates may be delayed or prevented. We rely substantially on third-party data managers for our clinical trial data. There is no assurance that these third parties will not make errors in the design, management or retention of our data or data systems. There is no assurance that these third parties will pass FDA or regulatory audits, which could delay or prohibit regulatory approval.

Our CROs may also have relationships with other commercial entities, including our competitors, for whom they may also be conducting clinical trials or other product development activities, which could harm our competitive position. If any of our relationships with these third-party CROs terminate, we may not be able to enter into arrangements with alternative CROs or to do so on commercially reasonable terms. Further, switching or adding additional CROs involves additional cost and requires management time and attention. In addition, there is a natural transition period when a new CRO commences work. As a result, delays may occur, which could materially impact our ability to meet our desired clinical development timelines. Though we carefully manage our relationships with our CROs, there can be no assurance that we will not encounter challenges or delays in the future or that these delays or challenges will not have a material adverse impact on our business, financial condition and prospects.

The timelines of our clinical trials may be impacted by numerous factors and any delays may adversely affect our ability to execute our current business strategy.

Clinical testing is expensive, difficult to design and implement, can take many years to complete, and is uncertain as to outcome. We may experience delays in clinical trials at any stage of development and testing of our product candidates. Our planned clinical trials may not begin on time, have an effective design, enroll a sufficient number of subjects, or be completed on schedule, if at all.

Events which may result in a delay or unsuccessful completion of clinical trials include:

inability to raise funding necessary to initiate or continue a trial;

delays in obtaining regulatory approval to commence a trial;

delays in reaching agreement with the FDA on final trial design;

delays in recruiting patients with the specific genetic alterations we are targeting to participate in a trial;

imposition of a clinical hold following an inspection of our clinical trial operations or trial sites by the FDA or other regulatory authorities;

delays in reaching agreement on acceptable terms with prospective CROs and clinical trial sites;

delays in obtaining required institutional review board approval at each site;

delays in having subjects complete participation in a trial or return for post-treatment follow-up;

delays caused by subjects dropping out of a trial due to side effects or otherwise;

clinical sites dropping out of a trial to the detriment of enrollment;

time required to add new clinical sites; and

delays by our contract manufacturers to produce and deliver a sufficient supply of clinical trial materials.

For example, due to the targeted indications and patient populations we intend to focus on for development of our product candidates, the number of study sites and patient populations available to us may be limited, and therefore enrollment of suitable patients to participate in clinical trials for these product candidates may take longer than would be the case if we were pursuing broader indications or patient populations. In addition, some of our competitors are developing targeted oncology therapeutics for non-small cell lung cancer ("NSCLC") which could limit our ability to enroll patients and complete our planned clinical trials in a timely manner.

Furthermore, enrollment may depend on the availability of suitable companion diagnostics to identify genetic markers we are targeting and the capability and willingness of clinical sites to conduct genetic screening of potential patients.

If initiation or completion of any of our clinical trials for our product candidates are delayed for any of the above reasons or for other reasons, our development costs may increase, our approval process could be delayed, any periods after commercial launch and before expiration of patent protection may be reduced and our competitors may have more time to bring products to market before we do. Any of these events could impair the commercial potential of our product candidates and could have a material adverse effect on our business.

Our product candidates may cause undesirable side effects or have other properties that could delay or prevent their regulatory approval, limit the commercial profile of an approved product label, or result in significant negative consequences following marketing approval, if any.

Undesirable side effects caused by our product candidates could cause us or regulatory authorities to interrupt, delay or halt clinical trials and could result in a more restrictive label or the delay or denial of regulatory approval by the FDA or other comparable foreign authorities. Results of our trials could reveal a high and unacceptable severity and prevalence of side effects. In such an event, our trials could be suspended or terminated and the FDA or comparable foreign regulatory authorities could order us to cease further development of or deny approval of our product candidates for any or all targeted indications. Treatment-related side effects could affect patient recruitment or the ability of enrolled patients to complete the trial, or result in potential product liability claims. Any of these occurrences may harm our business, financial condition and prospects significantly.

Additionally, if one or more of our product candidates receives marketing approval, and we or others later identify undesirable side effects caused by such products, a number of potentially significant negative consequences could result, including:

regulatory authorities may withdraw approvals of such product;

regulatory authorities may require additional warnings on the product label;

we may be required to create a medication guide outlining the risks of such side effects for distribution to patients;

we could be sued and held liable for harm caused to patients; and

our reputation may suffer.


Any of these events could prevent us from achieving or maintaining market acceptance of any product candidate, if approved, and could significantly harm our business, results of operations and prospects.

We are and continue to be subject to stringent government regulations concerning the clinical testing of our products. We will also continue to be subject to government regulation of any product that receives regulatory approval.

Numerous statutes and regulations govern human testing and the manufacture and sale of human therapeutic products in the United States and other countries where we intend to market our products. Such legislation and regulation bears upon, among other things, the approval of trial protocols and human testing, the approval of manufacturing facilities, testing procedures and controlled research, the review and approval of manufacturing, preclinical and clinical data prior to marketing approval, including adherence to GMP during production and storage, and marketing activities including advertising and labeling.

Clinical trials may be delayed or suspended at any time by us or by the FDA or other similar regulatory authorities if it is determined at any time that patients may be or are being exposed to unacceptable health risks, including the risk of death, or if compounds are not manufactured under acceptable GMP conditions or with acceptable quality. Current regulations relating to regulatory approval may change or become more stringent. The agencies may also require additional trials be run in order to provide additional information regarding the safety, efficacy or equivalency of any product candidate for which we seek regulatory approval.

Moreover, any regulatory approval of a drug which is eventually obtained may entail limitations on the indicated uses for which that drug may be marketed or on the conditions of approval, or contain requirements for potentially costly post-marketing testing, including Phase 4 clinical trials, and surveillance to monitor the safety and efficacy of the product candidate. In addition, if the FDA or a comparable foreign regulatory authority approves any of our product candidates, the manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion and recordkeeping for the product will be subject to extensive and ongoing regulatory requirements. These requirements include submissions of safety and other post-marketing information and reports, registration, as well as continued compliance with GMPs and GCPs for any clinical trials that we conduct post-approval. Furthermore, product approvals may be withdrawn or limited in some way if problems occur following initial marketing or if compliance with regulatory standards is not maintained. Similar restrictions are imposed in foreign markets. Regulatory agencies could become more risk averse to any side effects or set higher standards of safety and efficacy prior to reviewing or approving a product. This could result in a product not being approved.

If we, or any future marketing collaborators or contract manufacturers, fail to comply with applicable regulatory requirements, we may be subject to sanctions including fines, product recalls or seizures and related publicity requirements, injunctions, total or partial suspension of production, civil penalties, suspension or withdrawals of previously granted regulatory approvals, warning or untitled letters, refusal to approve pending applications for marketing approval of new products or of supplements to approved applications, import or export bans or restrictions, and criminal prosecution and penalties. Any of these penalties could delay or prevent the promotion, marketing or sale of our products and product candidates.

The FDA’s policies, and policies of comparable foreign regulatory authorities, may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our product candidates. If we are slow or unable to adapt to changes in existing requirements or to adopt new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained, which would adversely affect our business, prospects and ability to achieve or sustain profitability.

*We have no experience in clinical or commercial manufacturing and depend on others for the production of our product candidates at suitable levels of quality and quantity. Any problems or delays in the manufacture of our products would have a negative impact on our ability to successfully execute our development and commercialization strategies.


We do not currently have nor do we plan to acquire the infrastructure or capability internally to manufacture our clinical drug supplies for use in the conduct of our clinical trials, and we lack the resources and the capability to manufacture any of our product candidates on a clinical or commercial scale. We rely on collaborators and/or third parties for development, scale-up, formulation, optimization, management of clinical trial and commercial scale manufacturing and commercialization. There are no assurances we can scale-up, formulate or manufacture any product candidate in sufficient quantities with acceptable specifications for the conduct of our clinical trials or for the regulatory agencies to grant approval of such product candidate. We have not yet commercialized any products and have no commercial manufacturing experience. To be successful, our products must be properly formulated, scalable, stable and safely manufactured in clinical trial and commercial quantities in compliance with GMP and other regulatory requirements and at acceptable costs. Should any of our suppliers or our collaborators be unable to supply or be delayed in supplying us with sufficient supplies, no assurance can be given that we will be able to find alternative means of supply in a short period of time. Should such parties’ operations suffer a material adverse effect, the manufacturing of

our products would also be adversely affected. Furthermore, key raw materials could become scarce or unavailable. There may be a limited number of third parties who can manufacture our products. We may not be able to meet specifications previously established for product candidates during scale-up and manufacturing. In conjunction with the review of our NDA for adagrasib, FDA may be unable to conduct necessary inspections due to pandemic restrictions, and even if they are able to conduct such inspections, may find conditions that prevent approval of our NDA.


Our reliance on third parties to manufacture our product candidates will expose us and our partners to risks including the following, any of which could delay or prevent the commercialization of our products, result in higher costs, or deprive us of potential product revenue:


Contract manufacturers can encounter difficulties in achieving the scale-up, optimization, formulation, or volume production of a compound as well as maintaining quality control with appropriate quality assurance. They may also experience shortages of qualified personnel. Contract manufacturers are required to undergo a satisfactory GMP
29

inspection prior to regulatory approval and are obliged to operate in accordance with FDA, International Conference onCouncil for Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use ("ICH"(“ICH”), European and other nationally mandated GMP regulations and/or guidelines governing manufacturing processes, stability testing, record keeping and quality standards. A failure of these contract manufacturers to follow GMP and to document their adherence to such practices or failure of an inspection by a regulatory agency may lead to significant delays in the availability of our product candidate materials for clinical study, leading to delays in our trials.


For each of our current product candidates we will initially rely on a limited number of contract manufacturers. Changing these or identifying future manufacturers may be difficult. Changing manufacturers requires re-validation of the manufacturing processes and procedures in accordance with FDA, ICH, European and other mandated GMP regulations and/or guidelines. Such re-validation may be costly and time-consuming. It may be difficult or impossible for us to quickly find replacement manufacturers on acceptable terms, if at all.terms.


Our contract manufacturers may not perform as agreed or may not remain in the contract manufacturing business for the time required to produce, store and distribute our products successfully.


The successfulA variety of risks associated with operating our business internationally could adversely affect our business.

In addition to our operations in the United States, we have operations in the Netherlands, and are pursuing further European expansion to support the planned commercialization of our product candidates if approved, will depend on achieving market acceptancein the EEA and we may not be ableUK. We face risks associated with our international operations, including possible unfavorable political, tax and labor conditions, which could harm our business. We are subject to gain sufficient acceptance to generate significant revenue.numerous risks associated with international business activities, including:


Even if our product candidates are successfully developeddifficulties in staffing and receive regulatory approval, they may not gain market acceptance among physicians, patients, healthcare payors such as private insurers or governmentsmanaging foreign operations;

foreign government taxes, regulations and permit requirements;

United States and foreign government tariffs, trade restrictions, price and exchange controls and other funding partiesregulatory requirements;

anti-corruption laws, including the Foreign Corrupt Practices Act (“FCPA”);

economic weakness, including inflation, natural disasters, war, events of terrorism or political instability in particular foreign countries;

fluctuations in currency exchange rates, which could result in increased operating expenses and the medical community. The degree of market acceptancereduced revenues, and other obligations related to doing business in another country;

compliance with tax, employment, immigration and labor laws, regulations and restrictions for any of our products will depend on a number of factors, including:employees living or traveling abroad;


demonstration of the clinical efficacy and safety of our products;

the prevalence and severity of any adverse side effects;

limitations or warnings containedworkforce uncertainty in countries where labor unrest is more common than in the product’s approved labeling;United States;


cost-effectivenessproduction shortages resulting from any events affecting raw material supply or manufacturing capabilities aboard; and availability of acceptable pricing;


competitive product profile versus alternative treatment methodschanges in diplomatic and the superiority of alternative treatment or therapeutics;trade relationships.

the effectiveness of marketing and distribution methods and support for the products; and

coverage and reimbursement policies of government and third-party payors to the extent that our products could receive regulatory approval but not be approved for coverage by or receive adequate reimbursement from government and quasi-government agencies or other third-party payors.

Disease indications may be small subsets of a disease that could be parsed into smaller and smaller indications as different subsets of diseases are defined. This increasingly fine characterization of diseases could have negative consequences; including creating an approved indication that is so small as not to have a viable market for us. If future technology allows characterization of a disease in a way that is different from the characterization used for large pivotal studies, it may make those studies invalid or reduce their usefulness, and may require repeating all or a portion of the studies. Future technology may supply better prognostic ability which could reduce the portion of patients projected to need a new therapy. Even after being cleared by regulatory authorities, a product may later be shown to be unsafe or not to have its purported effect, thereby preventing its widespread use or requiring withdrawal from the market.

If we fail to obtain coverage and adequate reimbursement for our products, our revenue-generating ability will be diminished and there is no assurance that the anticipated market for our products will be sustained.

We believe that there will be many different applications for products successfully derived from our technologies and that the anticipated market for products under development will continue to expand. However, due to competition from existing or new products and the yet-to-be established commercial viability of our products, no assurance can be given that these beliefs will prove to be correct. Physicians, patients, formularies, payors or the medical community in general may not accept or utilize any products that we or our collaborative partners may develop. Other drugs may be approved during our clinical testing which could change the accepted treatments for the disease targeted and make our product candidates obsolete.


Our and our collaborators’ ability to commercialize our products successfully will depend, in part, on the extent to which coverage and adequate reimbursement for such products and related treatments will be available from governmental health payor programs at the federal and state levels, including Medicare and Medicaid, private health insurers, managed care plans and other organizations. No assurance can be given that third-party coverage and adequate reimbursement will be available that will allow us to maintain price levels sufficient for the realizationbusiness activities outside of an appropriate return on our investment in product development.

Coverage and adequate reimbursement from governmental healthcare programs, such as Medicare and Medicaid, and private health insurers, managed care plans and other organizations is critical to new product acceptance. Coverage decisions may depend upon clinical and economic standards that disfavor new drug products when more established or lower cost therapeutic alternatives are already available or subsequently become available. Even if we obtain coverage for our product candidates, the resulting reimbursement payment rates might not be adequate or may require co-payments that patients find unacceptably high. Patients are unlikely to use our product candidates unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost of our product candidates.

In the United States are subject to the FCPA and similar anti-bribery or anti-corruption laws, regulations or rules of other countries in which we operate. The FCPA and similar anti-corruption laws generally prohibit offering, promising, giving, or authorizing others to give anything of value, either directly or indirectly, to non-U.S. government officials in order to improperly influence any act or decision, secure any other improper advantage, or obtain or retain business. The FCPA also requires public companies to make and keep books and records that accurately and fairly reflect the transactions of the company and to devise and maintain an adequate system of internal accounting controls. As described above, our business is heavily regulated and therefore involves significant interaction with public officials, including officials of non-U.S. governments. Additionally, in many other countries, pricing and/or profitability of some or all prescriptionthe health care providers who prescribe pharmaceuticals and biopharmaceuticals are subject to varying degrees of government control. In the United States, there has recently been increased government enforcement and government and payor scrutiny relating to drug pricing and price increases. For example, there have been several recent U.S. Congressional inquiries and proposed federal and state legislation designed to, among other things, bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drugs, and such measures, if enacted, could adversely impact the prices we or our future collaborators may charge for our products candidates, if commercialized. Outside of the United States, the successful commercialization of our products will depend largely on obtaining and maintaining government coverage, because in many countries patients are unlikely to use prescription drugs that are not coveredemployed by their government, healthcare programs. Negotiating coverage and reimbursement with governmental authorities can delay commercialization by 12 months or more. Coverage and reimbursement policies may adversely affect our ability to sell our products on a profitable basis. In many international markets, governments control the prices of prescription pharmaceuticals, including through the implementation of reference pricing, price cuts, rebates, revenue-related taxes and profit control, and we expect prices of prescription pharmaceuticals to decline over the life of the product or as volumes increase.

Healthcare reform and controls on healthcare spending may limit the price we charge for any products and the amounts thereof that we can sell. In particular, in the United States, the federalpurchasers of pharmaceuticals are government entities; therefore, any dealings with these prescribers and private insurers have changed and have considered ways to change, the manner in which healthcare services are provided. In March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act (collectively, the "ACA"), became law in the United States. With respect to pharmaceutical products, the ACA, among other things, expanded and increased industry rebates for drugs covered by Medicaid and made changes to the coverage requirements under Medicare Part D, Medicare’s prescription drug benefits program. Some of the provisions of the ACA have yet topurchasers may be fully implemented, while certain provisions have been subject to judicialregulation under the FCPA. Recently the Securities and Congressional challenges, as well as efforts by the Trump administration to repeal or replace certain aspects of the ACA. For example, in Congress, the U.S. House of Representatives passed ACA replacement legislation known as the American Health Care Act of 2017 in May 2017, which was not introduced in the Senate. More recently, the Senate Republicans have proposed multiple bills to repeal or repealExchange Commission (“SEC”) and replace portions of the ACA. Although none of these measures have been enacted by Congress, Congress may consider other legislation to repeal or replace certain elements of the ACA. In addition, since January 2017, President Trump has signed two Executive Orders designed to delay the implementation of certain provisions of the ACA or otherwise circumvent some of the requirements for health insurance mandated by the ACA. Further, citing legal guidance from the U.S. Department of Justice and the U.S. Department of Health and Human Services, the Trump administration has concluded that cost-sharing reduction (“CSR”DOJ”) paymentshave increased their FCPA enforcement activities with respect to insurance companies requiredpharmaceutical companies. In addition, under the ACA haveDodd–Frank Wall Street Reform and Consumer Protection Act, private individuals who

report to the SEC original information that leads to successful enforcement actions may be eligible for a monetary award. We are engaged in ongoing efforts that are designed to ensure our compliance with these laws, including due diligence, training, policies, procedures and internal controls. However, there is no certainty that all employees and third-party business partners (including our distributors, wholesalers, agents, contractors, and other partners) will comply with anti-bribery laws. In particular, we do not received necessary appropriations from Congresscontrol the actions of manufacturers and announced that it will discontinueother third-party agents, although we may be liable for their actions. Violation of these payments immediately until such appropriations are made. The loss of the CSR payments is expected to increase premiums on certain policies issued by qualified health plans under the ACA. While Congress is considering legislation to appropriate funds for CSR payments the future of that

legislation is uncertain. We cannot predict how the ACA, its possible repeal or replacement or other potential future healthcare reform may impact our operations.

In addition, other legislative changes have been proposed and adopted since the ACA was enacted. In August 2011, the Budget Control Act of 2011, among other things, created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required goals, thereby triggering the legislation’s automatic reduction to several government programs. These changes include aggregate reductions to Medicare payments to providers of up to 2% per fiscal year, which went into effect on April 1, 2013 and, as amended, will stay in effect through 2025 unless additional Congressional action is taken. In January 2013, President Obama signed into law the American Taxpayer Relief Act of 2012, which, among other things, further reduced Medicare payments to several types of providers and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. Moreover, the Drug Supply Chain Security Act, enacted in 2013, imposes new obligations on manufacturers of pharmaceutical products related to product tracking and tracing. These new laws may result in civil or criminal sanctions, which could include monetary fines, criminal penalties, and disgorgement of past profits, which could have a material adverse impact on our business and financial condition.

We are or may become subject to tax audits in the Netherlands or other countries into which we expand our operations, and such jurisdictions may assess additional reductions in Medicareincome tax against us. The final determination of tax audits could be materially different from our recorded income tax provisions and other healthcare funding, whichaccruals. The ultimate results of an audit could have a material adverse effect on our customersoperating results or cash flows in the period or periods for which that determination is made and accordingly,could result in increases to our overall tax expense in subsequent periods.

These and other risks associated with our international operations may materially adversely affect our business, financial condition and results of operations.


The COVID-19 pandemic could adversely impact our business including our ongoing and planned clinical trials and preclinical research.

Our business could be materially adversely affected by the effects of health epidemics. For example, since December 2019, a novel strain of coronavirus, SARS-CoV-2, causing a disease referred to as COVID-19, has spread worldwide. In March 2020, the World Health Organization declared the COVID-19 outbreak a pandemic and the U.S. government-imposed travel restrictions on travel between the U.S., Europe and certain other countries. In addition, the Governor of the State of California issued a number of stay at home orders and health directives. As a result of such orders, we implemented work-from-home policies for most of our employees and generally suspended business-related travel. Although many of these orders and directives have since been lifted, in response to the spread of various variants of COVID-19 and to protect the health and welfare of our employees, we continue to maintain flexible work-from-home policies for most of our employees. The effects of these work-from-home and travel policies have thus far had a limited impact on our business.

Our business could be materially adversely affected by health epidemics in regions where we or our partners have concentrations of clinical trial sites or other business operations and could cause significant disruption in the operations of third-party manufacturers and contract research organizations upon whom we rely.

Quarantines, shelter-in-place, executive and similar government orders, or the perception that such orders, shutdowns or other restrictions on the conduct of business operations could occur, could impact personnel at third-party manufacturing facilities in the U.S. and other countries, or the availability or cost of materials, which would disrupt our supply chain. We have experienced impacts to our clinical trial operations due to the COVID-19 pandemic. Some examples of these impacts include:

we have experienced impact on clinical site initiation and patient enrollment due to restrictions imposed as a result of the COVID-19 pandemic;

some patients have not been able to comply with clinical trial protocols as quarantines have impeded patient movement and interrupted healthcare services;

we have experienced some impact on our ability to recruit and retain patients and principal investigators and site staff who, as healthcare providers, may have heightened exposure to COVID-19; and

we have experienced some delays in necessary interactions with regulators, ethics committees and other important agencies and contractors due to limitations in employee resources or forced furlough of government or contractor personnel.

The global COVID-19 pandemic continues to rapidly evolve. While we have not yet experienced material adverse effects to our business as a result of the COVID-19 pandemic, the ultimate impact of the COVID-19 pandemic or a similar health epidemic is highly uncertain and could have negative impact our business, financial condition and operating results.

*We rely upon third-party contractors and service providers for the execution of some aspects of our development programs. Failure of these collaborators to provide services of a suitable quality and within acceptable timeframes may cause the delay or failure of our development programs.
31


We anticipateoutsource certain functions, tests and services to CROs, medical institutions and collaborators and outsource manufacturing to collaborators and/or contract manufacturers, and we rely on third parties for quality assurance, clinical monitoring, clinical data management and regulatory expertise. In particular, we rely on CROs to run our clinical trials on our behalf and contract manufacturers to manufacture our product candidates. There is no assurance that such individuals or organizations will be able to provide the ACA,functions, tests, drug supply or services as well as alternativeagreed upon or replacement healthcare reform measures thatto acceptable quality standards, and we could suffer significant delays in the development of our products or processes. In particular, certain third party service providers may be adoptedunable to comply with their contractual obligations to us due to disruptions caused by the COVID-19 pandemic, including reduced operations or headcount reductions, or otherwise, and in certain cases we may have limited recourse if the non-compliance is due to factors outside of the service provider’s control.

In some cases, there may be only one or few providers of such services, including manufacturing services. In addition, the cost of such services could increase significantly over time. We rely on third parties as mentioned above to enroll qualified patients and conduct, supervise and monitor our clinical trials. Our reliance on these third parties and collaborators for clinical development activities reduces our control over these activities, but does not relieve us of our regulatory responsibilities, including ensuring that our clinical trials are conducted in accordance with good clinical practices (“GCP”) regulations and the investigational plan and protocols contained in the regulatory agency applications. In conjunction with their review of our NDA for adagrasib, FDA will inspect certain of our clinical trial sites for GCP compliance, and any significant GCP violations or data integrity concerns could prevent the approval of our NDA. In addition, these third parties may not complete activities on schedule or may not manufacture compounds under GMP conditions. Preclinical studies may not be performed or completed in accordance with good laboratory practices, regulatory requirements or our trial design. If we or our CROs fail to comply with GCP regulations, the clinical data generated in our clinical trials may be deemed unreliable and the FDA, the European Medicines Agency (“EMA”) or comparable foreign regulatory authorities may require us to perform additional clinical trials before approving any marketing applications. If these third parties or collaborators do not successfully carry out their contractual duties or meet expected deadlines, obtaining regulatory approval for manufacturing and commercialization of our product candidates may be delayed or prevented. We rely substantially on third-party data managers for our clinical trial data. There is no assurance that these third parties will not make errors in the design, management or retention of our data or data systems. There is no assurance that these third parties will pass FDA or regulatory audits, which could delay or prohibit regulatory approval.

Our CROs may also have relationships with other commercial entities, including our competitors, for whom they may also be conducting clinical trials or other product development activities, which could harm our competitive position. If any of our relationships with these third-party CROs terminate, we may not be able to enter into arrangements with alternative CROs or to do so on commercially reasonable terms. Further, switching or adding additional CROs involves additional cost and requires management time and attention. In addition, there is a natural transition period when a new CRO commences work. As a result, delays may occur, which could materially impact our ability to meet our desired clinical development timelines. Though we carefully manage our relationships with our CROs, there can be no assurance that we will not encounter challenges or delays in the future may result in more rigorous coverage criteriaor that these delays or challenges will not have a material adverse impact on our business, financial condition and additional downward pressure on the reimbursement we may receive for any approved product. Moreover, payment methodologies may be subject to changes in healthcare legislation and regulatory initiatives.prospects.

In addition, levels of reimbursement may be impacted by other current and future legislation, regulation or reimbursement policies of third-party payors in a manner that may harm the demand and reimbursement available for our products, including for companion diagnostics for our products, which in turn, could harm our future product pricing and sales. Any reduction in reimbursement from Medicare and other government programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability or commercialize our products.


Competition in our targeted market area is intense and this field is characterized by rapid technological change. Therefore, developments by competitors may substantially alter the predicted market or render our product candidates uncompetitive.


We are aware of at least six companies who currently have competing commercial or clinical-stage direct KRAS G12C inhibitor programs: Amgen, Inc., F. Hoffman-LaRoche Ltd., Eli Lilly and Company, Merck & Co., Inc, Novartis AG and Boehringer Ingelheim International GmbH.

There are hundreds of drugs in clinical development today inseveral immune checkpoint inhibitors currently approved for use as single agents to treat multiple tumor types, including NSCLC. To augment the area of oncology therapeutics. We have competitors both in the United States and internationally, including major multinational pharmaceutical companies, biotechnology companies and universities and other research institutions. In the oncology market, our major competitors include, but are not limited to: AbbVie, Inc., AstraZeneca PLC, Exelixis Inc., GlaxoSmithKline PLC, Ignyta, Inc., BergenBio, Blueprint Medicines, Loxo Oncology, Syndax Pharmaceuticals Inc., Merck KGaA, NantPharma LLC, Novartis AG, Pfizer Inc. Sanofi S. A., and Janssen among others.

Many companies have filed, and continue to file, patent applications in oncology which may or could affect our program. Someefficacy of these patent applications may have already been allowed or issued,agents, combination studies are being conducted with a variety of potentially synergistic mechanisms, including inhibitors of CTLA-4, LAG3, TIM-3, TIGIT and others may issueCSF-1R, among others. Most of these combination studies are being conducted in the future. These companiespatients who are naïve to immune checkpoint inhibitor therapy. Direct mechanistic competitors to sitravatinib in combination with checkpoint inhibitors in NSCLC patients who had previously failed checkpoint inhibitor therapy include butCABOMETYX® (Exelixis, Inc.) and LENVIMA® (Eisai Co., Ltd.), both anti-VEGF agents that also inhibit other receptor tyrosine kinases. Additionally, there are not limited to: Bristol-Myers Squibb Company; Compugen Limited; Exelixis; GlaxoSmithKline PLC; Novartis; Pfizer and Araxes Pharma LLC. Since this area is competitive andnumerous other potential competitors with kinase inhibitors that are being evaluated in combination with checkpoint inhibitors in NSCLC patients who had previously failed checkpoint inhibitor therapy in earlier lines of strong interest to pharmaceutical and biotechnology companies, there will likely be additional patent applications filed, and additional patents granted, in the future, as well as additional research and development programs expected in the future.treatment.

In addition to companies that have HDAC inhibitors or kinase inhibitors addressing oncology indications,our targets of interest, our competition also includes hundreds of private and publicly traded companies that operate in the area of oncology but have therapeutics with different mechanisms of action. The oncology market in general is highly competitive with over 1,000 molecules currently in clinical development. Other important competitors, in addition to those mentioned above, are small and large biotechnology companies, specialty and regional pharmaceutical companies and multinational pharmaceutical companies, including but not limited to AbbVie Inc., AstraZeneca plc, Bristol-Myers Squibb Company, Gilead Sciences, Inc., GlaxoSmithKline plc, Johnson & Johnson, Pfizer Inc., Sanofi S.A., and Takeda Pharmaceutical Co.


Developments by others may render our products or technologies non-competitive or obsolete or we may not be able to keep pace with technological developments. Our competitors may have developed or may be developing technologies which may be the basis for competitive products. Some of these products may prove to be more effective and less costly than the products developed or being developed by us. Our competitors may obtain regulatory approval for their products more rapidly than we do which may change the standard of care in the indications we are targeting, rendering our technology or products non-competitive or obsolete.non-competitive. For example, with the recent approval of immunotherapy agents for the treatment of NSCLC and other cancers, the standard of care for the treatment of cancer is evolving and will continue to evolve which could require us to change the design and timelines for our registration trailstrials and may limit the commercial acceptance of our products in the future. Others may develop

treatments or cures superior to any therapy we are developing or will develop. Moreover, alternate, less toxic forms of medical treatment may be developed which may be competitive with our products.


Many of the organizations which could be considered to be our competitors have substantially more financial and technical resources, more extensive discovery research, preclinical research and development capabilities and greater manufacturing, marketing, distribution, production and human resources than we do. Many of our current or potential competitors have more experience than uswe do in research, preclinical testing and clinical trials, drug commercialization, manufacturing and marketing, and in obtaining domestic and foreign regulatory approvals. In addition, failure, unacceptable toxicity, lack of sales or disappointing sales or other issues regarding competitors’ products or processes could have a material adverse effect on our product candidates, including our clinical candidates or our lead compounds. Established pharmaceutical companies may invest heavily to accelerate discovery and development of novel compounds or to in-license novel compounds that could make our product candidates less competitive. In addition, any new product that competes with an approved product must demonstrate compelling advantages in efficacy, convenience, tolerability and safety in order to overcome price competition and brand recognition and to be commercially successful. Accordingly, our competitors may succeed in obtaining patent protection, receiving FDA, EMA, or other regulatory approval or discovering, developing and commercializing medicines before we do, which would have a material adverse impact on our business.


We will not be able to successfully commercializeOur product candidates may cause undesirable side effects or have other properties that could delay or prevent their regulatory approval, limit the commercial profile of an approved product label, or result in significant negative consequences following marketing approval, if any.

Undesirable side effects caused by our product candidates without establishing salescould cause us or regulatory authorities to interrupt, delay or halt clinical trials and marketing capabilities internallycould result in a more restrictive label or through collaborators.

We currently have no salesthe delay or denial of regulatory approval by the FDA or other comparable foreign authorities. Results of our trials could reveal a high and marketing staff. We may notunacceptable severity and prevalence of side effects. In such an event, our trials could be ablesuspended or terminated and the FDA or comparable foreign regulatory authorities could order us to find suitable sales and marketing staff and collaborators for allcease further development of or deny approval of our product candidates. We have no prior experiencecandidates for any or all targeted indications. Treatment-related side effects could affect patient recruitment or the ability of enrolled patients to complete the trial, or result in the marketing, sale and distribution of pharmaceutical products and there are significant risks involved in building and managing a sales organization, including our ability to hire, retain and incentivize qualified individuals, generate sufficient sales leads, provide adequate training to sales and marketing personnel, and effectively manage a geographically dispersed sales and marketing team. Any collaborators may not be adequate or successful or could terminate or materially reduce the effort they direct to our products. The development of a marketing and sales capability will require significant expenditures, management resources and time. The cost of establishing such a sales force may exceed any potential product revenue,liability claims. Any of these occurrences may harm our business, financial condition and prospects significantly.

Additionally, if one or more of our product candidates receives marketing approval, and sales effortswe or others later identify undesirable side effects caused by such products, a number of potentially significant negative consequences could result, including:

regulatory authorities may be unsuccessful. If we are unable to develop an internal marketing and sales capability in a timely fashion, or at all, or if we are unable to enter into a marketing and sales arrangement with a third partywithdraw approvals of such product;

regulatory authorities may require additional warnings on acceptable terms, the product label;

we may be unablerequired to successfully developcreate a medication guide outlining the risks of such side effects for distribution to patients;

we could be sued and seek regulatory approvalheld liable for harm caused to patients; and

our reputation may suffer.
33


Any of these events could prevent us from achieving or maintaining market acceptance of any product candidates and/or effectively marketcandidate, if approved, and sell approved products, if any.could significantly harm our business, results of operations and prospects.


We are subject to competition for our skilled personnel and may experience challenges in identifying and retaining key personnel that could impair our ability to conduct our operations effectively.


Our future success depends on our ability to retain our executive officers and to attract, retain and motivate qualified personnel. If we are not successful in attracting and retaining highly qualified personnel, we may not be able to successfully implement our business strategy. Although we have not experienced problems attracting and retaining highly qualified personnel in the recent past, our industry has experienced a high rate of turnover of management personnel in recent years. Our ability to compete in the highly competitive biotechnology and pharmaceuticals industries depends upon our ability to attract and retain highly qualified managerial, scientific and medical personnel. We are highly dependent on our management, scientific and medical personnel, especially Charles M. Baum, M.D., Ph.D., our President and Chief Executive Officer, Isan Chen, M.D., our Executive Vice President and Chief Medical and Development Officer, James Christensen, Ph.D. our Chief Scientific Officer, Jamie A. Donadio, our Senior Vice President and Chief Financial Officer, and Chris LeMasters, our Executive Vice President and Chief Business Officer whose services are critical to the successful implementation of our product candidate acquisition,candidates, development and regulatory strategies, as well as the management of our financial operations. We are not aware of any present intention of any of these individualspersonnel to leave our Company. In order to induce valuable employees to continue their employment with us, we have provided stock optionsequity awards that vest over time. The value to employees of stock optionsequity awards that vest over time is significantly affected by movements in our stock price that are beyond our control, and may at any time be insufficient to counteract more lucrative offers from other companies.


Despite our efforts to retain valuable employees, members of our management, scientific and development teams may terminate their employment with us at any time, with or without notice. The loss of the services of any of our executive officers or other key employees and our inability to find suitable replacements could harm our business, financial condition and prospects. Our success also depends on our ability to continue to attract, retain and motivate highly skilled junior, mid-level and senior managers as well as junior, mid-level and senior scientific and medical personnel.


We may alsowill continue to experience growth in the number of our employees and the scope of our operations, especially in clinical development.operations. This growth will place a significant strain on our management, operations and financial resources and we may have

difficulty managing this future potential growth. No assurance can be provided that we will be able to attract new employees to assist in our growth. Many of the other pharmaceutical companies that we compete against for qualified personnel have greater financial and other resources, different risk profiles and a longer history in the industry than we do. We also may employ consultants or part-time and contract employees. There can be no assurance that these individuals are retainable. While we have been able to attract and retain skilled and experienced personnel and consultants in the past, no assurance can be given that we will be able to do so in the future.


*We have attempted, and may in the future attempt, to obtain FDA approval of adagrasib, sitravatinib or other product candidates through the use of the accelerated approval pathway. If we are unable to obtain such approval, we may be required to await the completion of planned or ongoing clinical trials or conduct additional clinical trials, which could increase the expense of obtaining, and delay the receipt of, necessary approval. Even if we receive accelerated approval from the FDA, if our confirmatory trials do not verify clinical benefit, or if we do not comply with rigorous post-marketing requirements, the FDA may seek to withdraw accelerated approval.

Our NDA for adagrasib for the treatment of previously-treated KRASG12C-mutated NSCLC is being reviewed by FDA for accelerated approval. We may in the future seek accelerated approval for our one or more of our product candidates. Under the accelerated approval program, the FDA may grant accelerated approval to a product candidate designed to treat a serious or life-threatening condition that provides meaningful therapeutic benefit over available therapies upon a determination that the product candidate has an effect on a surrogate endpoint or intermediate clinical endpoint that is reasonably likely to predict clinical benefit. The FDA considers a clinical benefit to be a positive therapeutic effect that is clinically meaningful in the context of a given disease, such as irreversible morbidity or mortality. For the purposes of accelerated approval, a surrogate endpoint is a marker, such as a laboratory measurement, radiographic image, physical sign, or other measure that is thought to predict clinical benefit, but is not itself a measure of clinical benefit. An intermediate clinical endpoint is a clinical endpoint that can be measured earlier than an effect on irreversible morbidity or mortality that is reasonably likely to predict an effect on irreversible morbidity or mortality or other clinical benefit. The accelerated approval pathway may be used in cases in which the advantage of a new drug over available therapy may not be a direct therapeutic advantage, but is a clinically important improvement from a patient and public health perspective. If granted, accelerated approval is usually contingent on the sponsor’s agreement to conduct, in a diligent manner, additional post-approval confirmatory studies to verify and describe the drug’s clinical benefit. If such post-approval studies fail to confirm the drug’s clinical benefit, the FDA may withdraw its approval of the drug.

34

Prior to seeking accelerated approval for any of our product candidates, we intend to seek feedback from the FDA and will otherwise evaluate our ability to seek and receive accelerated approval. There can be no assurance that after our evaluation of the feedback and other factors we will decide to pursue or submit an NDA for accelerated approval. If we decide to submit an application for accelerated approval for our product candidates, there can be no assurance that such submission or application will be accepted or that review or approval will be granted on a timely basis, or at all. A failure to obtain accelerated approval would result in a longer time period to commercialization of such product candidate, could increase the cost of development of such product candidate and could harm our competitive position in the marketplace.

If we or third parties are unable to successfully develop companion diagnostics for our product candidates, or experience significant delays in doing so, we may not achieve marketing approval or realize the full commercial potential of such product candidates.

A key part of our development strategy for our product candidates is to identify subsets of patients with specific types of tumors that express specific genetic markers. Identification of these patients will require the use and development of companion diagnostics. The FDA generally will either require approval or clearance of the diagnostic at the same time the FDA approves the therapeutic product, or as a post-marketing commitment at the time of the therapeutic product’s approval. We do not have experience or capabilities in developing or commercializing diagnostics and plan to rely in large part on third parties to perform these functions.

Companion diagnostics are subject to regulation by the FDA and comparable foreign regulatory authorities as medical devices and will likely require separate regulatory approval prior to commercialization. If we or third parties are unable to successfully develop companion diagnostics for our product candidates, or experience delays in doing so:

the development of these product candidates may be delayed because it may be difficult to identify patients for enrollment in our clinical trials in a timely manner;

these product candidates may not receive marketing approval if their safe and effective use depends on a companion diagnostic; and

we may not realize the full commercial potential of these product candidates that receive marketing approval if, among other reasons, we are unable to appropriately identify patients or types of tumors with the specific genetic alterations targeted by these product candidates.

Even if our product candidates and any associated companion diagnostics are approved for marketing, the need for companion diagnostics may slow or limit adoption of our product candidates. Although we believe genetic testing is becoming more prevalent in the diagnosis and treatment of cancer, our product candidates may be perceived negatively compared to alternative treatments that do not require the use of companion diagnostics, either due to the additional cost of the companion diagnostic or the need to complete additional procedures to identify genetic markers prior to administering our product candidates.

If any of these events were to occur, our business and growth prospects would be harmed, possibly materially.

Interim, topline and preliminary data from our clinical trials may change as more patient data become available, and are subject to audit and verification procedures that could result in material changes in the final data.

From time to time, we may publicly disclose preliminary, interim or topline data from our preclinical studies and clinical trials, which is based on a preliminary analysis of then-available data, and the results and related findings and conclusions are subject to change as patient enrollment and treatment continues and more patient data become available. Adverse differences between previous preliminary or interim data and future interim or final data could significantly harm our business prospects. We may also announce topline data following the completion of a preclinical study or clinical trial, which may be subject to change following a more comprehensive review of the data related to the particular study or trial. We also make assumptions, estimations, calculations and conclusions as part of our analyses of data, and we may not have received or had the opportunity to fully and carefully evaluate all data. As a result, the interim, topline or preliminary results that we report may differ from future results of the same studies, or different conclusions or considerations may qualify such results, once additional data have been received and fully evaluated. Preliminary, interim, or topline data also remain subject to audit and verification procedures that may result in the final data being materially different from the data we previously published. As a result, preliminary, interim, and topline data should be viewed with caution until the final data are available.

35

Further, others, including regulatory agencies, may not accept or agree with our assumptions, estimates, calculations, conclusions or analyses or may interpret or weigh the importance of data differently, which could impact the value of the particular program, the approvability or commercialization of the particular product candidate or product and our company in general. In addition, the information we choose to publicly disclose regarding a particular study or clinical trial is based on what is typically extensive information, and you or others may not agree with what we determine to be material or otherwise appropriate information to include in our disclosure.

The timelines of our clinical trials may be impacted by numerous factors and any delays may adversely affect our ability to execute our current business strategy.

Clinical testing is expensive, difficult to design and implement, can take many years to complete, and is uncertain as to outcome. We may experience delays in clinical trials at any stage of development and testing of our product candidates. Our planned clinical trials may not begin on time, have an effective design, enroll a sufficient number of subjects, or be completed on schedule, if at all.

Events which may result in a delay or unsuccessful completion of clinical trials include:

inability to raise funding necessary to initiate or continue a trial;

delays in obtaining regulatory approval to commence a trial;

delays in reaching agreement with the FDA or other regulatory authorities on final trial design;

imposition of a clinical hold following an inspection of our clinical trial operations or trial sites by the FDA or other regulatory authorities;

delays in reaching agreement on acceptable terms with prospective CROs and clinical trial sites;

delays in obtaining required institutional review board approval at each site;

delays in having subjects complete participation in a trial or return for post-treatment follow-up;

delays caused by subjects dropping out of a trial due to side effects or otherwise;

delays caused by or relating to the COVID-19 pandemic;

clinical sites dropping out of a trial to the detriment of enrollment;

time required to add new clinical sites; and

delays by our contract manufacturers to produce and deliver a sufficient supply of clinical trial materials.

Furthermore, enrollment may depend on the availability of suitable companion diagnostics to identify genetic markers we are targeting and the capability and willingness of clinical sites to conduct genetic screening of potential patients.

If initiation or completion of any of our clinical trials for our product candidates are delayed for any of the above reasons or for other reasons, our development costs may increase, our approval process could be delayed, any periods after commercial launch and before expiration of patent protection may be reduced and our competitors may have more time to bring products to market before we do. Any of these events could impair the commercial potential of our product candidates and could have a material adverse effect on our business.

If we experience delays or difficulties in the enrollment of patients in clinical trials, those clinical trials could take longer than expected to complete and our receipt of necessary regulatory approvals could be delayed or prevented.

We may not be able to initiate or complete clinical trials for our product candidates if we are unable to locate and enroll a sufficient number of eligible patients to participate in these trials. In particular, because we are focused on patients with specific genetic alterations in some of our trials, our pool of suitable patients may be smaller and more selective and our ability to enroll a sufficient number of suitable patients may be limited or take longer than anticipated. In addition, some of our competitors have ongoing clinical trials for product candidates that treat the same indications, including NSCLC, where we are
36

studying adagrasib in monotherapy and in combination with other anticancer therapies, and sitravatinib in combination with checkpoint inhibitors, or target the same genetic alterations as our product candidates. Therefore, patients who would otherwise be eligible for our clinical trials may instead enroll in clinical trials of our competitors’ product candidates.

Patient enrollment for any of our clinical trials may also be affected by other factors, including without limitation:

the severity of the disease under investigation

the frequency of the genetic alteration we are seeking to target in the applicable trial, and the ability to effectively identify such alteration;

the willingness of clinical sites and principal investigators to subject candidate patients to genetic screening;

the eligibility criteria for the study in question;

the perceived risks and benefits of the product candidate under study;

the availability, effectiveness and safety of other treatment options;

the patient referral practices of physicians;

the ability to monitor patients adequately during and after treatment; and

the proximity and availability of a sufficient number of clinical trial sites that are willing to comply with the requirements of our clinical protocols.

For example, due to the targeted indications and patient populations we intend to focus on for development of our product candidates, the number of study sites and patient populations available to us may be limited, and therefore enrollment of suitable patients to participate in clinical trials for these product candidates may take longer than would be the case if we were pursuing broader indications or patient populations.

We are and continue to be subject to stringent government regulations concerning the clinical testing of our products. We will also continue to be subject to government regulation of any product that receives regulatory approval.

Numerous statutes and regulations govern human testing and the manufacture and sale of human therapeutic products in the United States, EEA, UK and other countries where we intend to market our products. Such legislation and regulation bears upon, among other things, the approval of trial protocols and human testing, the approval of manufacturing facilities, testing procedures, CMC and controlled research, the review and approval of manufacturing, preclinical and clinical data prior to marketing approval, including adherence to GMP during production and storage, and marketing activities including advertising and labeling.

Clinical trials may be delayed or suspended at any time by us or by the FDA or other similar regulatory authorities if it is determined at any time that patients may be or are being exposed to unacceptable health risks, including the risk of death, or if compounds are not manufactured under acceptable GMP conditions or with acceptable quality. Current regulations relating to regulatory approval may change or become more stringent. The agencies may also require additional trials be run in order to provide additional information regarding the safety, efficacy or equivalency of any product candidate for which we seek regulatory approval.

Moreover, any regulatory approval of a drug which is eventually obtained may entail limitations on the indicated uses for which that drug may be marketed or on the conditions of approval, or contain requirements for potentially costly post-marketing testing, including Phase 4 clinical trials, and surveillance to monitor the safety and efficacy of the product candidate. These requirements include submissions of safety and other post-marketing information and reports, registration, as well as continued compliance with GMPs and GCPs for any clinical trials that we conduct post-approval. In addition, if the FDA or a comparable foreign regulatory authority approves any of our product candidates, the manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion and recordkeeping for the product will be subject to extensive and ongoing regulatory requirements. For example, prescription drugs may be promoted only for the approved indications in accordance with the approved label. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses, and a company that is found to have improperly promoted off-label uses may be subject to significant liability. However, physicians may, in their independent medical judgment, prescribe legally
37

available products for off-label uses. The FDA does not regulate the behavior of physicians in their choice of treatments, but the FDA does restrict manufacturer’s communications on the subject of off-label use of their products. Furthermore, product approvals may be withdrawn or limited in some way if problems occur following initial marketing or if compliance with regulatory standards is not maintained. Similar restrictions are imposed in foreign markets. Regulatory agencies could become more risk averse to any side effects or set higher standards of safety and efficacy prior to reviewing or approving a product. This could result in a product not being approved.

If we, or any future marketing collaborators or contract manufacturers, fail to comply with applicable regulatory requirements, we may be subject to sanctions including fines, product recalls or seizures and related publicity requirements, injunctions, total or partial suspension of production, civil penalties, suspension or withdrawals of previously granted regulatory approvals, warning or untitled letters, refusal to approve pending applications for marketing approval of new products or of supplements to approved applications, import or export bans or restrictions, and criminal prosecution and penalties. Any of these penalties could delay or prevent the promotion, marketing or sale of our products and product candidates.

The FDA’s policies, and policies of comparable foreign regulatory authorities, may change and additional government regulations may be enacted that could prevent, limit or delay regulatory approval of our product candidates. If we are slow or unable to adapt to changes in existing requirements or to adopt new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval that we may have obtained, which would adversely affect our business, prospects and ability to achieve or sustain profitability.

Breakthrough therapy designation by the FDA, even if granted for any of our product candidates, may not lead to a faster development or regulatory review or approval process and it does not increase the likelihood that our product candidates will receive marketing approval.

We received breakthrough therapy designation for adagrasib for the treatment of patients with NSCLC with the KRAS G12C mutation following prior systemic therapy, and we may seek breakthrough therapy designation for future product candidates. A breakthrough therapy is defined as a drug or biologic that is intended, alone or in combination with one or more other drugs or biologics, to treat a serious or life-threatening disease or condition and preliminary clinical evidence indicates that the drug, or biologic, may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development. For product candidates that have been designated as breakthrough therapies, sponsors may obtain more frequent interaction with and communication with the FDA to help to identify the most efficient path for clinical development.

The receipt of a breakthrough therapy designation for a product candidate may not result in a faster development process, review or approval and does not change the approval standards or assure ultimate approval by the FDA. In addition, the FDA may later decide that the product no longer meets the conditions for qualification. As such, there can be no assurance that even if we do receive breakthrough therapy designation, that such designation will have a material impact on our development program.

The failure to (i) maintain the BeiGene Agreement or the failure of BeiGene to perform its obligations under the BeiGene Agreement and/or (ii) maintain the Zai Agreement or the failure of Zai to perform its obligations under the Zai Agreement, could, in each case, negatively impact our business.

Pursuant to the terms of the BeiGene Agreement, we granted to BeiGene an exclusive license to develop, manufacture and commercialize sitravatinib in the BeiGene Licensed Territory. Consequently, our ability to generate any revenues from sitravatinib in the BeiGene Licensed Territory depends on our ability to maintain our collaboration with BeiGene. We have limited control over the amount and timing of resources that BeiGene will dedicate to these efforts.

Pursuant to the terms of the Zai Agreement, we granted Zai the right to research, develop, manufacture and exclusively commercialize adagrasib in the Zai Licensed Territory. Consequently, our ability to generate any revenues from adagrasib in the Zai Licensed Territory depends on our ability to maintain our collaboration with Zai. We have limited control over the amount and timing of resources that Zai will dedicate to these efforts.

We are subject to a number of other risks associated with our dependence on the BeiGene Agreement with respect to sitravatinib in the BeiGene Licensed Territory and the Zai Agreement with respect to adagrasib in the Zai Licensed Territory, including:

BeiGene or Zai may not comply with applicable regulatory guidelines with respect to developing, manufacturing or commercializing sitravatinib or adagrasib, respectively, which could adversely impact sales or future development of
38

sitravatinib in or outside of the BeiGene Licensed Territory or adagrasib in or outside of the Zai Licensed Territory, respectively;

There may be disputes between us and BeiGene or Zai, including disagreements regarding the BeiGene Agreement or the Zai Agreement, respectively; and

BeiGene or Zai may not properly defend our intellectual property rights, or may use our proprietary information in such a way as to invite litigation that could jeopardize or invalidate our intellectual property rights or expose us to potential litigation.

Each of the BeiGene Agreement and Zai Agreement are also subject to early termination, including through BeiGene’s and Zai’s (as applicable) right to terminate without cause upon advance notice to us. If the agreement is terminated early, we may not be able to find another collaborator for the further development and commercialization of (i) with respect to BeiGene, sitravatinib in the BeiGene Licensed Territory and/or (ii) with respect to Zai, adagrasib in the Zai Licensed Territory, in each case on acceptable terms, or at all, and we may be unable to pursue continued development and commercialization of sitravatinib in the BeiGene Licensed Territory and/or adagrasib in the Zai Licensed Territory on our own.

*If we fail to obtain coverage and adequate reimbursement for our products, our revenue-generating ability will be diminished and there is no assurance that the anticipated market for our products will be sustained.

We believe that there will be many different applications for products successfully derived from our technologies and that the anticipated market for products under development will continue to expand. However, due to competition from existing or new products and the yet-to-be established commercial viability of our products, no assurance can be given that these beliefs will prove to be correct. Physicians, patients, formularies, payors or the medical community in general may not accept or utilize any products that we or our collaborative partners may develop. Other drugs may be approved during our clinical testing which could change the accepted treatments for the disease targeted and make our product candidates obsolete.

Our and our collaborators’ ability to commercialize our products successfully will depend, in part, on the extent to which coverage and adequate reimbursement for such products and related treatments will be available from governmental health payor programs at the federal and state levels, including Medicare and Medicaid, private health insurers, managed care plans and other organizations. No assurance can be given that third-party payor coverage and adequate reimbursement will be available that will allow us to maintain price levels sufficient for the realization of an appropriate return on our investment in product development.

Coverage and adequate reimbursement from governmental healthcare programs, such as Medicare and Medicaid, and private health insurers, managed care plans and other organizations is critical to new product acceptance. There is no uniform coverage and reimbursement policy among third-party payors in the United States; however, private third-party payors often follow Medicare coverage policy and payment limitations in setting their own reimbursement rates. Additionally, coverage decisions may depend upon clinical and economic standards that disfavor new drug products when more established or lower cost therapeutic alternatives are already available or subsequently become available. Even if we obtain coverage for our product candidates, the resulting reimbursement payment rates might not be adequate or may require co-payments that patients find unacceptably high. Patients are unlikely to use our product candidates unless coverage is provided and reimbursement is adequate to cover a significant portion of the cost of our product candidates.

Additionally, we or our collaborators may develop companion diagnostic tests for use with our product candidates. We or our collaborators will be required to obtain coverage and reimbursement for these tests separate and apart from the coverage and reimbursement we seek for our product candidates, once approved. While we have not yet developed any companion diagnostic test for use with our product candidates, if we do, there is significant uncertainty regarding our ability to obtain coverage and adequate reimbursement for the same reasons applicable to our product candidates.

In the United States and in many other countries, pricing and/or profitability of some or all prescription pharmaceuticals and biopharmaceuticals are subject to varying degrees of government control. In the United States, there has recently been increased government enforcement and government and payor scrutiny relating to drug pricing and price increases. For example, there have been several recent U.S. Congressional inquiries and proposed and enacted federal and state legislation designed to, among other things, bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs, and reform government program reimbursement methodologies for drugs. At the federal level, the Trump administration used several means to propose implementing drug pricing reform, including through federal budget proposals, executive orders and policy initiatives. For example, on July 24, 2020 and September 13, 2020, President Trump signed several executive orders aimed at lowering drug prices. As a result, the FDA released a final rule and guidance in
39

September, 2020, providing pathways for states to build and submit importation plans for drugs from Canada. Further, on November 20, 2020, the U.S. Department of Health and Human Services (“HHS”) finalized a regulation removing safe harbor protection for price reductions from pharmaceutical manufacturers to plan sponsors under Part D, either directly or through pharmacy benefit managers, unless the price reduction is required by law. The rule also creates a new safe harbor for price reductions reflected at the point-of-sale, as well as a new safe harbor for certain fixed fee arrangements between pharmacy benefit managers and manufacturers. The implementation of the rule has been delayed until January 1, 2026. On November 20, 2020, Centers for Medicare & Medicaid Services (“CMS”) issued an interim final rule implementing President Trump’s Most Favored Nation executive order, which would tie Medicare Part B payments for certain physician-administered drugs to the lowest price paid in other economically advanced countries. As a result of litigation challenging the Most Favored Nation model, on December 27, 2021, CMS published a final rule that rescinded the Most Favored Nation model interim final rule. In July 2021, the Biden administration released an executive order, “Promoting Competition in the American Economy,” with multiple provisions aimed at prescription drugs. In response to Biden’s executive order, on September 9, 2021, HHS released a Comprehensive Plan for Addressing High Drug Prices that outlines principles for drug pricing reform and sets out a variety of potential legislative policies that Congress could pursue to advance these principles. No legislation or administrative actions have been finalized to implement these principles. In addition, Congress is considering drug pricing as part of other reform initiatives. At the state level, legislatures have increasingly passed legislation and implemented regulations designed to control pharmaceutical and biological product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product access and marketing cost disclosure and transparency measures, and, in some cases, designed to encourage importation from other countries and bulk purchasing. These changes may adversely impact the prices we or our future collaborators may charge for our products candidates, if commercialized.

Outside of the United States, the successful commercialization of our products will depend largely on obtaining and maintaining government coverage, because in many countries, patients are unlikely to use prescription drugs that are not covered by their government healthcare programs. Negotiating coverage and reimbursement with governmental authorities can delay commercialization by 12 months or more. Coverage and reimbursement policies may adversely affect our ability to sell our products on a profitable basis. In many international markets, governments control the prices of prescription pharmaceuticals, including through the implementation of reference pricing, price cuts, rebates, revenue-related taxes and profit control, and we expect prices of prescription pharmaceuticals to decline over the life of the product or as volumes increase.

Healthcare reform and controls on healthcare spending may limit the price we charge for any products and the amounts thereof that we can sell. In particular, in the United States, the federal government and private insurers have changed, and have considered ways to change, the manner in which healthcare services are provided. In March 2010, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act (collectively, “ACA”) became law in the United States. With respect to pharmaceutical products, the ACA, among other things, expanded and increased industry rebates for drugs covered by Medicaid and made changes to the coverage requirements under Medicare Part D, Medicare’s prescription drug benefits program. Some of the provisions of the ACA have yet to be fully implemented, and there have been executive, judicial and Congressional challenges to certain aspects of the ACA. For example, on June 17, 2021 the U.S. Supreme Court dismissed a challenge on procedural grounds that argued the ACA is unconstitutional in its entirety because the “individual mandate” was repealed by Congress. Thus, the ACA will remain in effect in its current form. Further, prior to the U.S. Supreme Court ruling, on January 28, 2021, President Biden issued an executive order that initiated a special enrollment period for purposes of obtaining health insurance coverage through the ACA marketplace. The executive order also instructed certain governmental agencies to review and reconsider their existing policies and rules that limit access to healthcare, including among others, reexamining Medicaid demonstration projects and waiver programs that include work requirements, and policies that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the ACA. It is possible that the ACA will be subject to judicial or Congressional challenges in the future. It is unclear how any such challenges and the health reform measures of the Biden administration will impact the ACA and our business.

In addition, other legislative changes have been proposed and adopted since the ACA was enacted. In August 2011, the Budget Control Act of 2011, among other things, created measures for spending reductions by Congress. A Joint Select Committee on Deficit Reduction, tasked with recommending a targeted deficit reduction of at least $1.2 trillion for the years 2013 through 2021, was unable to reach required goals, thereby triggering the legislation’s automatic reduction to several government programs. These changes include aggregate reductions to Medicare payments to providers of up to 2% per fiscal year, which went into effect on April 1, 2013 and, as amended by subsequent legislation including the Bipartisan Budget Act of 2018, will stay in effect through 2030, except for a temporary suspension from May 1, 2020 through March 31, 2022 due to the COVID-19 pandemic, unless additional Congressional action is taken. Under current legislation, the actual reduction in Medicare payments will vary from 1% in 2022 to up to 3% in the final fiscal year of this sequester. On March 11, 2021, President Biden signed the American Rescue Plan Act of 2021 into law, which eliminates the statutory Medicaid drug rebate cap, currently set at 100% of a drug’s average manufacturer price, for single source and innovator multiple source drugs, beginning January 1, 2024. In January 2013, President Obama signed into law the American Taxpayer Relief Act of 2012,
40

which, among other things, further reduced Medicare payments to several types of providers and increased the statute of limitations period for the government to recover overpayments to providers from three to five years. These laws may result in additional reductions in Medicare and other healthcare funding, which could have a material adverse effect on our customers and accordingly, our financial operations.

We anticipate that the ACA, as well as alternative or replacement healthcare reform measures that may be adopted in the future, may result in more rigorous coverage criteria and additional downward pressure on the reimbursement we may receive for any approved product. It is possible that additional governmental action will be taken in response to the COVID-19 pandemic. Moreover, payment methodologies may be subject to changes in healthcare legislation and regulatory initiatives.

In addition, levels of reimbursement may be impacted by other current and future legislation, regulation or reimbursement policies of third-party payors in a manner that may harm the demand and reimbursement available for our products, including for companion diagnostics for our products, which in turn, could harm our future product pricing and sales. Any reduction in reimbursement from Medicare and other government programs may result in a similar reduction in payments from private payors. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability or commercialize our products.

Our potential future relationships with customers and third-party payors in the United States and elsewhere may be subject, directly or indirectly, to applicable anti-kickback, fraud and abuse, false claims, transparency, health information privacy and security and other healthcare laws and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm, administrative burdens and diminished profits and future earnings.


As a clinical-stage company that could potentially become a commercial pharmaceutical company, even though we do not and will not control referrals of healthcare services or bill directly to Medicare, Medicaid or other third-party payors, certain federal and state healthcare laws and regulations pertaining to fraud and abuse and patients’ rights are and will be applicable to our business. Our current andpotential future arrangements with third-party payors and customers may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations, including, without limitation, the federal Anti-Kickback Statute and the federal False Claims Act, which may constrain the business or financial arrangements and relationships through which we may sell, market and distribute any drugs for which we obtain marketing approval. In addition, we may be subject to transparency laws and patient privacy regulation by U.S. federal and state governments and by governments in foreign jurisdictions in which we conduct our business. The laws that may affect our ability to operate include:


the federal Anti-Kickback Statute, which prohibits, among other things, persons from knowingly and willfully soliciting, offering, receiving or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward, or in return for, either the referral of an individual for, or the purchase, order, lease, furnishing, prescribing or recommendation of, any good or service, for which payment may be made under federal and state healthcare programs, such as Medicare and Medicaid;Medicaid. The term “remuneration” has been broadly interpreted to include anything of value. The ACA, among other things, amended the intent requirement of the federal Anti‑Kickback Statute such that a person or entity no longer needs to have actual knowledge of the statute or specific intent to violate, in order to commit a violation;


federal civil and criminal false claims laws and civil monetary penalty laws, including the federal False Claims Act which impose criminal and civil penalties, includingcan be enforced by private individuals on behalf of the government through civil whistleblower or qui tam actions, againstand civil monetary penalty laws prohibit individuals or entities for knowingly presenting, or causing to be presented, to the federal government, including the Medicare and Medicaid programs, claims for payment that are false or fraudulent or making a false statement to avoid, decrease or conceal an obligation to pay money to the federal government;government. Entities can be held liable under these laws if they are deemed to “cause” the submission of false or fraudulent claims by, for example, providing inaccurate billing or coding information to customers, promoting a product off‑label, or for providing medically unnecessary services or items. In addition, a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal False Claims Act;


the federal Health Insurance Portability and Accountability Act of 1996 ("HIPAA"(“HIPAA”), which imposes criminal and civil liability for knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, including third-party payors, knowingly and willfully embezzling or stealing from a healthcare benefit program, willfully obstructing a criminal investigation of a healthcare offense, and knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statements relating toin connection with the delivery of or payment for healthcare matters;benefits, items or services;


41

HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009 ("HITECH"(“HITECH”), and their respective implementing regulations, which impose obligations on coveredcertain healthcare providers, health plans, and healthcare clearinghouses, known as covered entities, as well as their business associatesindividuals and entities that create, receive, maintain or transmit individually identifiable health information for or on behalf of a covered entity, known as business associates, as well as their covered subcontractors, with respect to safeguarding the privacy, security and transmission of individually identifiable health information;information. HITECH also created new tiers of civil monetary penalties, amended HIPAA to make civil and criminal penalties directly applicable to business associates, and gave state attorneys general new authority to file civil actions for damages or injunctions in U.S. federal courts to enforce the federal HIPAA laws and seek attorneys' fees and costs associated with pursuing federal civil actions;


the federal Open Payments program, which requires manufacturers of drugs, devices, biologics and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program, with specific exceptions, to report annually to CMS information related to “payments or other transfers of value” made to physicians, which is defined to include doctors, dentists, optometrists, podiatrists and chiropractors, other health care professionals (such as physician assistants and nurse practitioners), and teaching hospitals and applicable manufacturers and applicable group purchasing organizations to report annually to CMS ownership and investment interests held by the physicianssuch healthcare professionals and their immediate family members,members; and contains requirements for manufacturers to submit reports to CMS by the 90th day of each calendar year, and disclosure of such information to be made by CMS on a publicly available website; and


analogous state and foreign laws and regulations, such as state anti-kickback and false claims laws, which may apply to sales or marketing arrangements and claims involving healthcare items or services reimbursed by non-governmental third-party payors, including private insurers; state and foreign laws that require pharmaceutical companies to comply with the pharmaceutical industry’s voluntary compliance guidelines and the relevant compliance guidance promulgated by the federal government or otherwise restrict payments that may be made to healthcare providers; state and foreign laws that require drug manufacturers to report information related to payments and other transfers of value to physicians and other healthcare providers, marketing expenditures, or marketing expenditures;drug pricing; state and local laws that require the registration of pharmaceutical sales representatives; and state and foreign laws governing the privacy and security of health

information in certain circumstances, many of which differ from each other in significant ways and often are not preempted by HIPAA, thus complicating compliance efforts.


Because of the breadth of these laws and the narrowness of available statutory exceptions and regulatory exceptions,safe harbors, it is possible that some of our business activities could be subject to challenge under one or more of such laws. To the extent that any of our product candidates is ultimately sold in countries other than the United States, we may be subject to similar laws and regulations in those countries. If we or our operations are found to be in violation of any of the laws described above or any other governmental regulations that apply to us, we may be subject to penalties, including significant civil, criminal and criminaladministrative penalties, damages, fines, imprisonment, disgorgement, additional reporting obligations and oversight if we become subject to a corporate integrity agreement or other agreement to resolve allegations of non-compliance with these laws, exclusion from participation in government healthcare programs, and the curtailment or restructuring of our operations, any of which could have a material adverse effect on our business. If any of the physicians or other healthcare providers or entities with whom we expect to do business, including any of our collaborators, is found not to be in compliance with applicable laws, they may be subject to significant criminal, civil or administrative sanctions, including exclusion from participation in government healthcare programs, which could also materially affect our business.


*We are subject to stringent and changing obligations related to data privacy and security. Our actual or perceived failure to comply with such obligations could lead to regulatory investigations or actions; litigation; fines and penalties; disruptions of our business operations, reputational harm, and other adverse business impacts.

In the ordinary course of business, we process personal data and other sensitive data, including proprietary and confidential business data, trade secrets, intellectual property, data we collect about trial participants in connection with clinical trials, and sensitive third-party data. Our data processing activities also subject us to numerous data privacy and security obligations, such as various laws, regulations, guidance, industry standards, external and internal privacy and security policies, contracts, and other obligations that govern the processing of personal data by us and on our behalf.

In the United States, federal, state, and local governments have enacted numerous data privacy and security laws, including data breach notification laws, personal data privacy laws, and consumer protection laws. The California Consumer Privacy Act of 2018 (“CCPA”) imposes obligations on businesses to which it applies. These obligations include, without limitation, providing specific disclosures in privacy notices, affording California residents certain rights related to their personal data, and requiring businesses subject to the CCPA to implement certain measures to effectuate California residents’ personal data rights. The CCPA allows for statutory fines for noncompliance (up to $7,500 per violation). In addition, it is anticipated that the California Privacy Rights Act of 2020 (“CPRA”), effective January 1, 2023, will expand the CCPA. For example, the CPRA establishes a new California Privacy Protection Agency to implement and enforce the CCPA (as amended), which could
42

increase the risk of an enforcement action. Other states have enacted data privacy laws. For example, Virginia passed its Consumer Data Protection Act, Colorado passed the Colorado Privacy Act, and Utah passed the Utah Consumer Privacy Act, all of which differ from the CPRA and become effective in 2023.

Outside the United States, an increasing number of laws, regulations, and industry standards apply to data privacy and security. For example, the European Union’s General Data Protection Regulation (“EU GDPR”) and the UK’s GDPR (“UK GDPR”) impose strict requirements for processing the personal data of individuals located, respectively, within the EEA and the UK. For example, under the EU GDPR, government regulators may impose temporary or definitive bans on data processing, as well as fines up to 20 million euros or 4% of the annual global revenue, whichever is greater. Further, individuals may initiate litigation related to our processing of their personal data.

Certain jurisdictions have enacted data localization laws and cross-border personal data transfers laws. For example, absent appropriate safeguards or other circumstances, the EU GDPR generally restricts the transfer of personal data to countries outside of the EEA, such as the United States, which the European Commission does not consider to provide an adequate level of personal data protection. The European Commission released a set of “Standard Contractual Clauses” that are designed to be a valid mechanism by which entities can transfer personal data out of the EEA to jurisdictions that the European Commission has not found to provide an adequate level of protection. Currently, these Standard Contractual clauses are a valid mechanism to transfer personal data outside of the EEA. The Standard Contractual Clauses, however, require parties that rely upon that legal mechanism to comply with additional obligations such as conducting transfer impact assessments to determine whether additional security measures are necessary to protect the at-issue personal data. Moreover, due to potential legal challenges, there exists some uncertainty regarding whether the Standard Contractual Clauses will remain a valid mechanism for personal data transfers out of the EEA. In addition, laws in Switzerland and the UK similarly restrict personal data transfers outside of those jurisdictions to countries such as the United States that do not provide an adequate level of personal data protection. In addition to European restrictions on cross-border personal data transfers, other jurisdictions have enacted or are considering similar cross-border personal data transfer laws and local personal data residency laws, any of which could increase the cost and complexity of doing business. If we cannot implement a valid compliance mechanism for cross-border personal data transfers, we may face increased exposure to regulatory actions, substantial fines, and injunctions against processing or transferring personal data from Europe or elsewhere. Inability to import personal data to the United States may significantly and negatively impact our business operations, including by limiting our ability to conduct clinical trial activities in Europe and elsewhere; limiting our ability to collaborate with parties subject to European and other data protection laws or requiring us to increase our personal data processing capabilities in Europe and/or elsewhere at significant expense.

Our obligations related to data privacy and security are quickly changing in an increasingly stringent fashion. These obligations may be subject to differing applications and interpretations, which may be inconsistent among jurisdictions or in conflict. Preparing for and complying with these obligations requires us to devote significant resources (including, without limitation, financial and time-related resources). These obligations may necessitate changes to our information technologies, systems, and practices and those of any third parties that process personal data on our behalf. In addition, these obligations may even require us to change to our business model. Although we endeavor to comply with all applicable data privacy and security obligations, we may at times fail (or be perceived to have failed) to do so. Moreover, despite our efforts, our personnel or third-parties upon whom we rely may fail to comply such obligations that impacts our compliance posture.

If we fail, or are perceived to have failed, to address or comply with data privacy and security obligations, we could face significant consequences. These consequences may include, but are not limited to, government enforcement actions (e.g., investigations, fines, penalties, audits, inspections and similar); litigation (including class-related claims); additional reporting requirements and/or oversight; bans on processing personal data; and orders to destroy or not use personal data. Any of these events could have a material adverse effect on our reputation, business, or financial condition, including but not limited to: loss of customers; interruptions or stoppages in our business operations (including clinical trials); inability to process personal data or operate in certain jurisdictions; limited ability to develop or commercialize our products; expenditure of time and resources to defend any claim or inquiry; adverse publicity; or revision or restructuring our operations.

Changes in funding for the FDA, the SEC and other government agencies, or shutdowns, travel restrictions or furloughs, could hinder their ability to hire and retain key leadership and other personnel, prevent new products and services from being developed or commercialized in a timely manner or otherwise prevent those agencies from performing normal functions on which the operation of our business may rely, which could negatively impact our business.

The ability of the FDA to review and approve new products can be affected by a variety of factors, including government budget and funding levels, travel restrictions, ability to hire and retain key personnel and accept payment of user fees, and statutory, regulatory, and policy changes. Average review times at the agency have fluctuated in recent years as a result. In addition, government funding of the SEC and other government agencies on which our operations may rely, including
43

those that fund research and development activities, is subject to the political process, which is inherently fluid and unpredictable.

Disruptions at the FDA and other agencies may also slow the time necessary for new drugs to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. For example, over the last several years, including most recently beginning on December 22, 2018, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA and the SEC, have had to furlough critical FDA, SEC and other government employees and stop critical activities. If a prolonged government shutdown occurs, it could significantly impact the ability of the FDA to timely review and process our regulatory submissions, which could have a material adverse effect on our business. Further, future government shutdowns could impact our ability to access the public markets and obtain necessary capital in order to properly capitalize and continue our operations.

We may become subject to the risk of product liability claims.


We face an inherent risk of product liability as a result of the clinical testing of our product candidates and will face an even greater risk if we commercialize any products. Human therapeutic products involve the risk of product liability claims and associated adverse publicity. Currently, the principal risks we face relate to patients in our clinical trials, who may suffer unintended consequences. Claims might be made by patients, healthcare providers, pharmaceutical companies or others. For example, we may be sued if any product we develop allegedly causes injury or is found to be otherwise unsuitable during product testing, manufacturing, marketing or sale. Any such product liability claims may include allegations of defects in manufacturing, defects in design, a failure to warn of dangers inherent in the product, negligence, strict liability and a breach of warranties. Claims could also be asserted under state consumer protection laws. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit commercialization of our product candidates, if approved. Even successful defense would require significant financial and management resources. Regardless of the merits or eventual outcome, liability claims may result in:


decreased demand for our product candidates;


injury to our reputation;


withdrawal of clinical trial participants;


initiation of investigations by regulators;


costs to defend the related litigation;


a diversion of management’s time and our resources;


substantial monetary awards to trial participants or patients;


product recalls, withdrawals or labeling, marketing or promotional restrictions;


loss of revenue from product sales; and


the inability to commercialize any of our product candidates, if approved.


We may not have or be able to obtain or maintain sufficient and affordable insurance coverage, and without sufficient coverage any claim brought against us could have a materially adverse effect on our business, financial condition or results of operations. We run clinical trials through investigators that could be negligent through no fault of our own and which could affect patients, cause potential liability claims against us and result in delayed or stopped clinical trials. We are required in many cases by contractual obligations to indemnify collaborators, partners, third-party contractors, clinical investigators and institutions. These indemnifications could result in a material impact due to product liability claims against us and/or these groups. We currently carry $10 million in product liability insurance, which we believe is appropriate for our clinical trials. Although we maintain such insurance, any claim that may be brought against us could result in a court judgment or settlement in an amount that is not covered, in whole or in part, by our insurance or that is in excess of the limits of our insurance coverage. Our insurance policies also have

various exclusions, and we may be subject to a product liability claim for which we have no coverage. We will have to pay any amounts awarded by a court or negotiated in a settlement that exceed our coverage limitations or that are not covered by our insurance, and we may not have, or be able to obtain, sufficient capital to pay such amounts.

44


Our business involves the controlled use of hazardous materials and as such we are subject to environmental and occupational safety laws. Continued compliance with these laws may incur substantial costs and failure to maintain compliance could result in liability for damages that may exceed our resources.


Our preclinical research, manufacturing and development processes involve the controlled use of hazardous and radioactive materials. We are subject to federal, local and foreign laws and regulations governing the use, manufacture, storage, handling and disposal of such materials and certain waste products. Our operations involve the use of hazardous and flammable materials, including chemicals and biological materials. Our operations also produce hazardous waste products. The risk of accidental contamination or injury from these materials cannot be completely eliminated. In the event of such an accident, we could be held liable for any damages that result, and any such liability could exceed our resources. We may not be adequately insured against this type of liability. We may be required to incur significant costs to comply with environmental laws and regulations in the future, and our operations, business or assets may be materially adversely affected by current or future environmental laws or regulations.


We may have to dedicate resources to the settlement of litigation.


Securities legislation in the United States, Canada and other countries makes it relatively easy for stockholdersshareholders to sue. This could lead to frivolous lawsuits which could take substantial time, money, resources and attention or force us to settle such claims rather than seek adequate judicial remedy or dismissal of such claims.


If we are required to defend patent infringement actions brought by third parties, or if we sue to protect our own patent rights or otherwise to protect our proprietary information and to prevent its disclosure, or if we are involved in other litigation, whether as a plaintiff or defendant, we may be required to pay substantial litigation costs and managerial attention may be diverted from business operations even if the outcome is in our favor. If we are required to defend our patents or trademarks against infringement by third parties, we may be required to pay substantial litigation costs and managerial attention and financial resources may be diverted from our research and development operations even if the outcome is in our favor.


If our information technology systems or data is or were compromised, we could experience adverse impacts resulting from such compromise, including, but not limited to interruptions to our operations such as our clinical trials, claims that we breached our data protection obligations, and harm to our reputation.

In the ordinary course of our business, we may collect, store, use, transmit, disclose or otherwise process proprietary, confidential, and sensitive data, including personal data (such as health-related data), intellectual property, and trade secrets. We are dependent upon our own or third-party information technology systems, infrastructure and data, to operate our business.

Cyberattacks, malicious internet-based activity, and online and offline fraud are prevalent and continue to increase. These threats are becoming increasingly difficult to detect. These threats come from a variety of sources. In addition to traditional computer “hackers,” threat actors, personnel misconduct or error (such as theft or misuse), sophisticated nation-state and nation-state supported actors now engage in attacks. We may be vulnerablesubject to disruption, damagea variety of evolving threats, including but not limited to social engineering attacks (including through phishing attacks), malicious code (such as viruses and financial obligationworms), malware (including as a result of system failures.advanced persistent threat intrusions), denial-of-service attacks (such as credential stuffing), ransomware attacks, supply-chain attacks, software bugs, server malfunction, software or hardware failures, loss of data or other information technology assets, adware, telecommunications failures, and other similar threats. Ransomware attacks, including those perpetrated by organized criminal threat actors, nation-states, and nation-state supported actors, are becoming increasingly prevalent and severe and can lead to significant interruptions in our operations, loss of data and income, reputational harm, and diversion of funds. Extortion payments may alleviate the negative impact of a ransomware attack, but we may be unwilling or unable to make such payments due to, for example, applicable laws or regulations prohibiting payments. Similarly, supply-chain attacks have increased in frequency and severity, and we cannot guarantee that third parties and infrastructure in our supply chain have not been compromised or that they do not contain exploitable defects or bugs that could result in a breach of or disruption to our information technology systems (including our products/operational activities) or the third-party information technology systems that support us and our operational activities. The COVID-19 pandemic and our remote workforce poses increased risks to our information technology systems and data, as more of our employees work from home, utilizing network connections outside our premises.


Despite the implementation of security measures, anyAny of the internal computer systems belongingpreviously identified or similar threats could cause a security incident. A security incident could result in unauthorized, unlawful or accidental acquisition, modification, destruction, loss, alteration, encryption, disclosure of or access to us,data. A security incident could disrupt our collaborators or(and third parties upon whom we rely) ability to provide our third-party service providers are vulnerable to damage from computer viruses, unauthorized access, natural disasters, terrorism, war and telecommunication and electrical failure.products. Any system failure, accident or security breach that causes interruptions in our own, in collaborators’ or in third-party service vendors’
45

operations could result in a material disruption of our drug discovery and development programs. programs or theft of our intellectual property. We may expend significant resources or modify our business activities (including our clinical trial activities) in an effort to protect against security incidents.

Certain data privacy and security obligations may require us to implement and maintain specific security measures, industry-standard or reasonable security measures to protect our information technology systems and data.

We devote considerable internal and external resources to implementing security measures to protect our systems and customers but these security measures cannot provide absolute security. We may be unable to detect vulnerabilities in our information technology systems (including our products) because such threats and techniques change frequently, are often sophisticated in nature, and may not be detected until after a security incident has occurred. Despite our efforts to identify and remediate vulnerabilities, if any, in our information technology systems (including our products), our efforts may not be successful. Further, we may experience delays in developing and deploying remedial measures designed to address any such identified vulnerabilities.

Potential breaches of our security measures and the accidental loss, inadvertent disclosure, or unapproved dissemination of proprietary information, intellectual property, or sensitive or confidential data about us, our employees, or our customers (including the potential loss or disclosure of such information or data as a result of employee error or other employee actions or inactions, hacking, fraud, social engineering, or other forms of deception) could expose us, our customers, or the individuals affected to a risk of loss or misuse of this information, result in litigation and potential liability for us, damage our brand and reputation, or otherwise materially adversely affect our business, results of operations, and financial condition. Applicable data privacy and security obligations may require us to notify relevant stakeholders of security incidents. Such disclosures are costly, and the disclosures or the failure to comply with such requirements, could lead to adverse impacts.

In addition, the cost and operational consequences of implementing further data protection measures could be significant and theft of our intellectual property or proprietary business information could require substantial expenditures to remedy. Further, we cannot be certain that (a) our liability insurance will be sufficient in type or amount to cover us against claims related to security breaches, cyberattacks and other related breaches; (b) such coverage will cover any indemnification claims against us relating to any incident, will continue to be available to us on economically reasonable terms, or at all; or (c) any insurer will not deny coverage as to any future claim. The successful assertion of one or more large claims against us that exceed available insurance coverage, or the occurrence of changes in our insurance policies, including premium increases or the imposition of large deductible or co-insurance requirements, could adversely affect our reputation, business, financial condition and results of operations.

In addition, we rely upon third-party contractors and service providers for the hosting, support and/or maintenance of some aspects of our computer hardware, computer software and telecommunications systems. Failure of those contractors and service providers to provide systems and services of a suitable quality and within acceptable timeframes may cause the delay or failure of our development programs, or loss of confidential or proprietary information. To the extent that any disruption or security breach results in a loss or damage to our data or applications, or inappropriate disclosure of confidential or proprietary information, we may incur liability, our drug discovery and development programs may be adversely affected and the further development of our product candidates may be delayed. Furthermore, we may incur additional costs to remedy the damages caused by thesesuch disruptions or security breaches.breaches could harm our reputation, compel us to comply with federal and/or state breach notification laws and foreign law equivalents, subject us to mandatory corrective action, require us to verify the correctness of database contents and otherwise subject us to litigation or other liability under laws and regulations that protect personal data, any of which could disrupt our business and/or result in increased costs.


Risks RelatingRelated to Our Financial Position and Capital Requirements

*We will require additional financing and may be unable to raise sufficient capital, which could lead us to delay, reduce or abandon development programs or commercialization.

Our operations have consumed substantial amounts of cash since inception. Our research and development expenses were $131.0 million and $104.1 million for the three months ended March 31, 2022 and 2021, respectively. Our net loss for the three months ended March 31, 2022 and 2021 were $188.4 million and $135.7 million, respectively. As of March 31, 2022, we had an accumulated deficit of $1.9 billion. We may require substantial additional capital to pursue additional clinical development for our lead clinical programs, including conducting late-stage clinical trials, manufacturing clinical supplies and developing other assets in our pipeline, and, if we are successful, to commercialize any of our current product candidates. If the UFDA or any foreign regulatory agency, such as the EMA requires that we perform studies or trials in addition to those that we currently anticipate with respect to the development of our product candidates, or repeat studies or trials, or if our clinical trials
46

are otherwise delayed or disrupted due to the COVID-19 pandemic or otherwise, our expenses would further increase beyond what we currently expect. We may not be able to adequately finance our development programs, which could limit our ability to move our programs forward in a timely and satisfactory manner or require us to abandon the programs, any of which would harm our business, financial condition and results of operations. Because successful development of our product candidates is uncertain, we are unable to accurately estimate the actual funds we will require to complete research and development and commercialize our product candidates.

If, at any point, we are unable to obtain funding from equity offerings or debt financings on a timely basis, we may be required to (1) seek additional collaborators for one or more of our product candidates at an earlier stage than otherwise would be desirable or on terms that are less favorable than might otherwise be available; (2) relinquish or license on unfavorable terms our rights to technologies or product candidates that we otherwise would seek to develop or commercialize ourselves; or (3) significantly curtail one or more of our research or development programs or cease operations altogether.

We may not generate revenue from sales of products. If any of our product candidates fail in clinical trials or do not gain regulatory approval, or if any of our product candidates, if approved, fail to achieve market acceptance, we may never become profitable. If one or more of our product candidates is approved for commercial sale and we retain commercial rights, we anticipate incurring significant costs associated with commercializing any such approved product candidate. Therefore, even if we are able to generate revenue from the sale of any approved product, we may never become profitable. Even if we achieve profitability in the future, we may not be able to sustain profitability in subsequent periods. Our ability to generate future revenue from product sales depends heavily on our success in:

completing development and clinical trial programs for our product candidates;

maintaining existing collaboration and licensing agreements and entering into additional ones;

seeking and obtaining marketing approvals for any product candidates that successfully complete clinical trials;

establishing and maintaining supply and manufacturing relationships with third parties;

successfully commercializing any product candidates for which marketing approval is obtained; and

successfully establishing a sales force and marketing and distribution infrastructure.

We are a clinical-stage company with no approved products and no product revenue. Consequently, we expect that our financial and operating results will vary significantly from period to period.

We are a clinical-stage company that has incurred losses since its inception and expect to continue to incur substantial losses in the foreseeable future. Biopharmaceutical product development is a highly speculative undertaking and involves a substantial degree of uncertainty.

Our actual financial condition and operating results have varied significantly in the past and are expected to continue to fluctuate significantly from quarter-to-quarter or year-to-year due to a variety of factors, many of which are beyond our control. Factors relating to our business that may contribute to these fluctuations include:

the success of our clinical trials through all phases of clinical development;

delays in the commencement, enrollment and timing of clinical trials;

delays due to force majeure;

our ability to secure and maintain collaborations, licensing or other arrangements for the future development and/or commercialization of our product candidates, as well as the terms of those arrangements;

our ability to obtain, as well as the timeliness of obtaining, additional funding to develop our product candidates;

the results of clinical trials or marketing applications for product candidates that may compete with our product candidates;

competition from existing products or new products that may receive marketing approval;
47


potential side effects of our product candidates that could delay or prevent approval or cause an approved drug to be taken off the market;

any delays in regulatory review and approval of our clinical development plans or product candidates;

our ability to identify and develop additional product candidates;

the ability of patients or healthcare providers to obtain coverage or sufficient reimbursement for our products;

our ability, and the ability of third parties such as CROs to adhere to clinical study and other regulatory requirements;

the ability of third-party manufacturers to manufacture our product candidates and key ingredients needed to conduct clinical trials and, if approved, successfully commercialize our products;

the costs to us, and our ability as well as the ability of any third-party collaborators, to obtain, maintain and protect our intellectual property rights;

costs related to and outcomes of potential intellectual property litigation;

our ability to adequately support future growth;

our ability to attract and retain key personnel to manage our business effectively; and

our ability to build our finance infrastructure and, to the extent required, improve our accounting systems and controls.

Accordingly, the likelihood of our success must be evaluated in light of many potential challenges and variables associated with a clinical-stage company, many of which are outside of our control, and past operating or financial results should not be relied on as an indication of future results. Fluctuations in our operating and financial results could cause our share price to decline. It is possible that in some future periods, our operating results will be above or below the expectations of securities analysts or investors, which could also cause our share price to decline.

Raising additional funds through debt or equity financing will be dilutive and raising funds through licensing agreements may be dilutive, restrict operations or relinquish proprietary rights.

To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of those securities could result in substantial dilution for our current shareholders and the terms may include liquidation or other preferences that adversely affect the rights of our current shareholders. Existing shareholders may not agree with our financing plans or the terms of such financings. In addition, the COVID-19 pandemic continues to rapidly evolve and may result in a significant disruption of global financial markets. Our ability to raise additional capital may be adversely impacted by potential worsening global economic conditions and the recent disruptions to, and volatility in, the credit and financial markets in the U.S. and worldwide resulting from the pandemic. If the disruption persists and deepens, we could experience an inability to access additional capital, which could in the future negatively affect our capacity to fund research and development programs, including discovery research, preclinical and clinical development activities. Moreover, the incurrence of debt financing could result in a substantial portion of our operating cash flow being dedicated to the payment of principal and interest on such indebtedness and could impose restrictions on our operations. In addition, if we raise additional funds through future collaboration and licensing arrangements, it may be necessary to relinquish potentially valuable rights to our products or proprietary technologies, or to grant licenses on terms that are not favorable to us. Additional funding may not be available to us on acceptable terms, or at all.

*Our ability to use our U.S. net operating loss carryforwards and certain other tax attributes may be limited.
Our U.S. federal net operating loss (“NOL”), carryforwards generated in tax years beginning before January 1, 2018, are only permitted to be carried forward for 20 years under applicable U.S. tax law. Under current law, our federal NOLs generated in tax years beginning after December 31, 2017, may be carried forward indefinitely, but the deductibility of such federal NOLs in tax years beginning after December 31, 2020, is limited to 80% of taxable income. It is uncertain if and to what extent various states will conform to federal tax laws. In addition, under Sections 382 and 383 of the Code, and corresponding provisions of state law, if a corporation undergoes an “ownership change,” which is generally defined as a greater than 50% change, by value, in its equity ownership over a three-year period, the corporation’s ability to use its pre-change NOL

carryforwards and other pre-change U.S. tax attributes (such as research tax credits) to offset its post-change income or taxes may be limited.

As a result, our NOL carryforwards generated in tax years beginning before January 1, 2018 may expire prior to being used. In addition, we believe that we have in the past undergone, and in the future it is possible we may undergo, additional ownership changes that could limit our ability to use all of our pre-change NOLs and other pre-change tax attributes (such as research tax credits) to offset our post-change income or taxes. Similar provisions of state tax law may also apply to limit our use of accumulated state tax attributes. In addition, at the state level, there may be periods during which the use of NOLs or other tax attributes is suspended or otherwise limited, which could accelerate or permanently increase state taxes owed. As a result, we may be unable to use all or a material portion of our NOLs and other tax attributes, which could adversely affect our future cash flows.

Risks Related to Our Intellectual Property


We may not obtain adequate protection for our product candidatesproducts and/or through patents and other intellectual property rights and as such, our competitive advantage in the marketplace may be compromised.


Our success depends in part,to a significant degree upon on our ability to develop, secure and protect our patents, trade secrets, trademarks and othermaintain intellectual property rights andto our proprietary products, to operate without infringing on the proprietary rights of others or having third parties circumvent the rights that we own or license. We have filed and are actively pursuing patent applications in the United States, Japan, Europe and other major markets via the Patent Cooperation Treaty or directly in countries of interest. The patent positionsHowever, we may not receive issued patents on any of healthcare companies, universities and biopharmaceutical companies, including ours, are uncertain and involve complex questions of law and fact for which important legal issues may remain unresolved. Therefore, there is no assurance that our pending patent applications will resultin these countries and we may not be able to obtain, maintain or enforce our patents and other intellectual property rights which could impact our ability to compete effectively. We cannot be certain that the U.S. Patent and Trademark Office, courts in the issuanceUnited States or the patent offices and courts in foreign countries will consider the claims in our patents and applications covering any of patents or that we will develop additional proprietaryour products which arein development as patentable. Moreover,In addition, the scope of any of our issued patents issued or to be issued to us may not be sufficiently broad to provide us with anya competitive advantage. Furthermore, other parties may successfully challenge, invalidate or circumvent our issued patents or patents licensed to us so that our patent rights do not create an effective competitive barrier. Our method-of-use patents protect the use of a product only for the specified method. This type of patent does not prevent a competitor from making and marketing a product that is identical to our product for an indication that is outside the scope of the patented method. Moreover, even if competitors do not actively promote their product for our targeted indications, physicians may prescribe these products off-label. Although off-label prescriptions may infringe or contribute to the infringement of method-of-use patents, the practice is common and such infringement is difficult to prevent, including through legal action. Further, if the patent applications we holdown or in-licenselicense with respect to our programs, product candidates andand/or companion diagnostic fail to issue, if their breadth or strength of protection is threatened, or if they fail to provide meaningful exclusivity for our product candidates, it could dissuade companies from collaborating with us to develop product candidates, and threaten our ability to commercialize future products.

Our patents may be challenged by third parties at the United States Patent and Trademark Office ("USPTO"), comparable foreign patent offices, or in patent litigation. In addition, it is possible that third parties with products that are very similar to ours will circumvent our patents by means of alternate designs or processes or file applications or be granted patents that would block or hurt our efforts.

There are no assurances that our patent counsel, lawyers or advisors have given us correct advice or counsel. Opinions from such patent counsel or lawyers may not be correct or may be based on incomplete facts. We cannot be certain that we are the first to invent or first to file for patent protection for the inventions covered by pending patent applications and, if we are not, we may be subject to priority disputes. We may be required to disclaim part or all of the subject matter and/or term of certain patents or all of the subject matter and/or term of certain patent applications. There may be prior art of which we are not aware that may affect the validity or enforceability of a patent claim. There also may be prior art of which we are aware, but which we do not believe affects the validity or enforceability of one or more claims, which may, nonetheless, ultimately be found to affect the validity or enforceability of a claim. No assurance can be given that if challenged, our patents would be declared by the USPTO, comparable foreign patent offices or a court to be valid or enforceable or that even if found valid and enforceable, a competitor’s technology or product would be found by a court to infringe our patents. The possibility exists that others will develop products which have the same effect as our products on an independent basis which do not infringe our patents or other intellectual property rights, or will design around the claims of patents that we have had issued that cover our products. The steps we have taken to protect our intellectual property may not prevent the misappropriation of our proprietary information and technologies, particularly in foreign countries where laws or law enforcement practices may not protect proprietary rights to the same extent as in the United States, Europe or Japan. Unauthorized disclosure of our proprietary information could also harm our competitive position. We could also inadvertently use our collaborators’ data inappropriately which could lead to liability. We may file patent applications but have claims restricted or we may not be able to supply sufficient data to satisfy a patent office to support our claims and, as a result, may not obtain the original claims desired or we may receive restricted claims. Alternatively, it is possible that we may not receive any patent protection from an application.

Maintaining our patents and applications requires timely payment of fees and other associated costs in the countries of filing, and we could inadvertently abandon a patent or patent application (or trademark or trademark application) due to non-payment of fees, or as a result of a failure to comply with filing deadlines or other requirements of the prosecution process, resulting in the loss of protection of certain intellectual property rights in a certain country. Alternatively, we, our collaborators or our patent counsel may take action resulting in a patent or patent application becoming abandoned which may not be able to be reinstated, or if reinstated, may suffer patent term adjustments. Any of these outcomes could hurt our ability to gain full patent protection for our products. Registered trademarks and/or applications for trademark registrations in the United States that belong to us are subject to similar risks as described above for patents and patent applications.

Many of our collaboration agreements are complex and may call for licensing or cross-licensing of potentially blocking patents, know-how or intellectual property. Due to the potential overlap of data, know-how and intellectual property rights there can be no assurance that one of our collaborators will not dispute our right to send data or know-how or other intellectual property rights to third parties and this may potentially lead to liability or termination of a program or litigation. There are no assurances that the actions of our collaborators would not lead to disputes or cause us to default with other collaborators. We cannot be certain that a collaborator will not challenge the validity of licensed patents.


We cannot be certain that any country’s patent and/or trademark office will not implement new rules which could affect how we draft, file, prosecute and/or maintain patents and patent applications, or that certain patent rights and/or trademark rights will be granted by governmental authorities in particular foreign countries. We cannot be certain that increasing costs for drafting, filing, prosecuting and maintaining patent applications and patents will not limit our ability to file for patent protection, or to prosecute applications through to grant. We may be forced to abandon or return the rights to specific patents due to a lack of financial resources. There is no assurance that we could enter into licensing arrangements at a reasonable cost, or develop or obtain alternative technology in respect of patents issued to third parties that incidentally cover our products. Any inability to secure such licenses or alternative technology could result in delays in the introduction of some of our products or even lead to prohibition of the development, manufacture or sale of certain products by us.


We may file applications for trademark registrations in connection with our product candidates in various jurisdictions, including the United States. No assurance can be given that any of our trademark applications will be registered in the United States or elsewhere, or that the use of any registered or unregistered trademarks will confer a competitive advantage in the marketplace. Furthermore, even if we are successful in our trademark registrations, the FDA and regulatory authorities in other countries have their own process for drug nomenclature and their own views concerning appropriate proprietary names. No assurance can be given that the FDA or any other comparable regulatory authority will accept any of our trademarks or will not request reconsideration of one of our trademarks, for use in connection with our drug product candidates, whether currently or at some time in the future. The loss, abandonment, or cancellation of any of our trademarks or trademark applications could negatively affect the success of the product candidates to which they relate.


Moreover, some of our know-how and technology which is not patented or not patentable may constitute trade secrets. Therefore, we require our consultants, advisors and collaborators to enter into confidentiality agreements and our employees to enter into invention and non-disclosure agreements. However, no assurance can be given that such agreements will provide for a meaningful protection of our trade secrets, know-how or other proprietary information in the event of any unauthorized use or disclosure of information. Furthermore, we cannot provide assurance that any of our employees, consultants, contract personnel or collaborators, either accidentally or through willful misconduct, will not cause serious negative impact to our programs and/or our strategy. All of our employees have signed confidentiality agreements, but there can be no assurance that they will not inadvertently or through their misconduct give trade secrets away.


Third-party patents or intellectual property infringement claims may result in a reduction in the scope of our patent protection and competitive exclusivity with respect to our product candidates. Patent litigation, including defense against third-party intellectual property claims, may result in us incurring substantial costs.


Patent applications which
49

Our patents may relatebe challenged by third parties from time to or affect our business maytime, and we will have been filed by others. Such patent applications or patents resulting there from may conflict with our technologies, patents or patent applications, potentially reducing the scope or strength of our patent protection, and may ultimately be determined to limit or prohibit our freedom to operate with respect to our product candidates. Such events could cause us to stop or change the course of our research and development or modifydefend our intellectual property strategies. We could also becomerights. If we are involved in interferencean intellectual property dispute, we may need to litigate to defend our rights or assert them against others. Disputes can involve arbitration, litigation or proceedings declared by the United States Patent and Trademark Office or the International Trade Commission or foreign patent authorities. These disputes can result in connection with one or morethe successful invalidation of our patents or reduction in scope so that our patent applicationsrights do not create an effective competitive barrier. Even if resolved in our favor, litigation or other legal proceedings relating to determine priority of invention, or in post-grant opposition proceedings at the USPTO or comparable foreign patent offices. There can be no guarantees that an interference proceeding or defense of a post-grant opposition would be successful or that such an outcome would be upheld on appeal. An unfavorable outcome could requireintellectual property claims may cause us to cease using the related technology or to attempt to license rights to itincur significant expenses and could distract our technical and management personnel from the prevailing party. Our businesstheir normal responsibilities. In addition, there could be harmedpublic announcements of the results of hearings, motions or other interim proceedings or developments and if securities analysts or investors perceive these results to be negative, it could have a substantial adverse effect on the prevailing party does not offer us a license on commercially reasonable terms. Our defenseprice of such interference proceedings may fail and, even if successful, may result in substantial costs and distract our management and other employees.common stock.


No assurance can be givenIt is possible that third parties will circumvent our patents once issued,by means of alternate designs or processes or file applications or be granted patents that would be declared byblock or hamper our efforts. Further, a court to be valid or enforceable, or that we would not be found to infringe a competitor’s patent.

Third parties may assert that we are using their proprietary information without authorization. Third parties may also have or obtain patents andthird party may claim that technologies licensed toour products or used by ustechnology infringe their patents. Because patent applications can take many years to issue, third parties may have currently pending patent applications which may later result in issued patents that our product candidates or companion diagnostic may infringe, or which such third parties claim are infringed by the use of our technologies. If any third-party patents are held by a court of competent jurisdiction to cover any aspect of our product candidates, including the formulation or method of use of such product candidate, the holders of any such patents may be able to block our ability to commercialize such product candidate unless we obtain a license under the applicableits patents or until such patents expire. In any such case, such a license may not be available on commercially reasonable terms or at all. We may attempt to invalidate a competitor’s patent or trademark. There is no assurance such action will ultimately be successful and, even if initially successful, it could be overturned upon appeal. In addition, any legal action that seeks damages or an injunction to stop us from carrying on our commercial activities relating to the affected technologies could subject us to monetary liability. Some of our

competitors may be able to sustain the costs of complex patent litigation more effectively than we can because they have substantially greater resources.

Parties making claims against us for alleged infringement of theirother intellectual property rights, as such we may obtain injunctivehave to discontinue or other equitable relief, which could effectively block our ability to further develop and commercialize one or more of our product candidates. Defense of these claims, regardless of their merit, would involve substantial litigation expense and would be a substantial diversion of employee resources from our business. In the event of a successful claim of infringement against us, we could be required to redesign our infringing products or obtain a license from such third party to continue developing and commercializingalter our products and technology. However, weprocesses, pay license fees or cease certain activities. We may not be able to obtain any requireda license to needed intellectual property on commercially reasonablefavorable terms, orif at all. Even if weThere are able to obtain a license, it may be non-exclusive, thereby giving our competitors access tomany patents issued or applied for in the same technologies licensed to us. It may be impossible to redesign our productsbiotechnology industry, and technology, or it may require substantial time and expense, which could force us to cease commercialization of one or more of our product candidates, or some of our business operations, which could materially harm our business. In addition, in any such proceeding, we may not be required to pay substantial damages, including treble damages and attorneys’ fees in the event we are found liable for willful infringement.

Our intellectual property may be infringed upon by a third party.

Third parties may infringe one or moreaware of our issued patents or trademarks. We cannot predict if, when or where a third party may infringe one or more of our issued patents or trademarks. There is no assurancepatent applications held by others that we would be successful in a court of law to prove that a third party is infringing one or more of our issued patents. Even if we are successful in proving in a court of law that a third party is infringing one or more of our issued patents there can be no assurance that we would be successful in halting their infringing activities, for example, through a permanent injunction, or that we would be fully or even partially financially compensated for any harmrelate to our business. We may be forcedThis is especially true since patent applications in the U.S. and elsewhere are filed confidentially for the first 18 months. Moreover, the validity and breadth of biotechnology patents involve complex legal and factual questions for which important legal issues remain.

Maintaining our patents and applications requires timely payment of fees and other associated costs in the countries of filing, and we could inadvertently abandon a patent or patent application (or trademark or trademark application) due to enter intonon-payment of fees, or as a licenseresult of a failure to comply with filing deadlines or other agreement withrequirements of the infringing third party at terms less profitable or otherwise less commercially acceptable to us than ifprosecution process, resulting in the license or agreement were negotiated under conditions between thoseloss of a willing licensee and a willing licensor. We may not become awareprotection of a third party infringer within legal timeframes that would enable us to seek adequate compensation, or at all, thereby possibly losing the ability to be compensated for any harm to our business. Such a third-party may be operatingcertain intellectual property rights in a foreign country where the infringer is difficult to locate, wherecertain country. Alternatively, we, doour collaborators or our patent counsel may take action resulting in a patent or patent application becoming abandoned which may not have issued patents and/or the patent laws may be more difficult to enforce. Some third-party infringers may be able to sustainbe reinstated, or if reinstated, may suffer negative patent term adjustments. Any of these outcomes could hurt our ability to gain full patent protection for our products. Registered trademarks and/or applications for trademark registrations in the costs of complexUnited States that belong to us are subject to similar risks as described above for patents and patent infringement litigation more effectively than we can because they have substantially greater resources. Any inability to stop third-party infringement could result in loss in market share of some of our products or even lead to a delay, reduction and/or inhibition of the development, manufacture or sale of certain products by us. There is no assurance that a product produced and sold by a third-party infringer would meet our or other regulatory standards or would be safe for use. Such third-party infringer products could irreparably harm the reputation of our products thereby resulting in substantial loss in market share and profits.applications.


Third parties may seek to obtain approval of a generic version of approved products. Defense against entry of a generic product may result in us incurring substantial costs and ultimate failure to prevail against approval of a generic product could result in a substantial loss of market share and profits.


Even if we are successful in obtaining regulatory approval to sell any of our product candidates in one or more countries, we cannot be certain that our patents and other intellectual property rights will ultimately prevent approval during the patent term
of generic products developed and commercialized by third parties. A generic manufacturer may seek approval of a generic version of any of our products in the United States by filing an Abbreviated New Drug Application ("ANDA"), with the FDA, asserting that our patents are invalid and/or unenforceable to maintain market exclusivity for any of our products, if approved. We cannot predict if, or when, one or more generic manufacturers may attempt to seek regulatory approval for a generic version of any of our products, if approved. There is no assurance that we will ultimately be successful in a court of law to prevent entry of a generic version of any of our products during the applicable patent term and we may incur substantial costs defending our patents and intellectual property rights. An inability to stop a generic manufacturer from selling a generic version of our products could result in a substantial loss of market share and profits or even preclude the ability to continue to commercialize any of our products, if approved.


Risks Related to Our Shares of Common Stock


*Our principal shareholders control the majority of our shares, and their actions may significantly influence matters submitted to our shareholders for approval and our share price.

Based on the information available to us as of March 31, 2022, our shareholders and their affiliates who owned more than 5% of our outstanding common stock collectively owned 38% of our outstanding common stock. Boxer Capital, LLC (“Boxer Capital”) and its affiliates collectively own 10% of our outstanding common stock. In addition, in conjunction with certain financing transactions, we granted Boxer Capital the right to nominate a member of our Board of Directors and the right to appoint an observer on our Board of Directors. In addition, we granted Baker Brothers Advisors, LLC (“Baker Brothers”) the right to appoint an observer on our Board of Directors. Collectively Baker Brothers and Boxer Capital may have significant influence over matters submitted to our shareholders for approval, including the election and removal of directors and the approval of any merger, consolidation, or sale of all or substantially all of our assets. Furthermore, if Boxer Capital, Baker Brothers, or any other of our major shareholders determine to exit from the industry or from their holdings in us, for whatever reason, the impact on our share price could be detrimental over a prolonged period of time.
50


Our bylaws, as amended (our “Bylaws”) provide that the Court of Chancery of the State of Delaware is the exclusive forum for certain disputes between us and our shareholders, which could limit our shareholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or employees.

Our Bylaws provide that the Court of Chancery of the State of Delaware will be the sole and exclusive forum for the following types of actions or proceedings under Delaware statutory or common law: (i) any derivative action or proceeding brought on our behalf, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors or officers to our company or our shareholders, (iii) any action asserting a claim against our company arising pursuant to any provision of the Delaware General Corporation Law or our amended and restated certificate of incorporation or Bylaws, or (iv) any action asserting a claim against our company governed by the internal affairs doctrine. This choice of forum provision does not apply to suits brought to enforce a duty or liability created by the Securities Act of 1933, as amended, or the Exchange Act, or any other claim for which the federal courts have exclusive jurisdiction.  

This choice of forum provision may limit a shareholder’s ability to bring certain claims in a judicial forum that it finds favorable for disputes with us or any of our directors, officers, other employees or shareholders, which may discourage lawsuits with respect to such claims, although our shareholders will not be deemed to have waived our compliance with federal securities laws and the rules and regulations thereunder. If a court were to find this choice of forum provision to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could adversely affect our business and financial condition.

Because we do not anticipate paying any cash dividends on our common stock in the foreseeable future, capital appreciation, if any, would be our shareholders’ only source of gain.

We have never declared or paid any cash dividends on our common shares, and we currently expect that earnings, if any, and cash flow will primarily be retained and used in our operations, including servicing any debt obligations we may have now or in the future. Accordingly, although we do not anticipate paying any dividends in the foreseeable future, we may not be able to generate sufficient cash flow in order to allow us to pay future dividends on, or make any distributions with respect to our common stock. As a result, capital appreciation, if any, of our common stock would be our shareholders’ sole source of gain on their investment in our common stock for the foreseeable future.

General Risks

As a public company in the United States, we incur significant legal and financial compliance costs and we are subject to the Sarbanes-Oxley Act. We can provide no assurance that we will, at all times, in the future be able to report that our internal controls over financial reporting are effective.
Companies that file reports with the SEC, including us, are subject to the requirements of Section 404 of the Sarbanes-Oxley Act of 2002. Section 404 requires management to establish and maintain a system of internal control over financial reporting, and annual reports on Form 10-K filed under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), must contain a report from management assessing the effectiveness of a company’s internal control over financial reporting. Ensuring that we have adequate internal financial and accounting controls and procedures in place to produce accurate financial statements on a timely basis remains a costly and time-consuming effort that needs to be re-evaluated frequently. Failure on our part to have effective internal financial and accounting controls would cause our financial reporting to be unreliable, could have a material adverse effect on our business, operating results, and financial condition, and could cause our stock price to decline as a result.

If we cannot conclude that we have effective internal control over our financial reporting, or if our independent registered public accounting firm is unable to provide an unqualified opinion regarding the effectiveness of our internal control over financial reporting, investors could lose confidence in the reliability of our financial statements. Failure to comply with reporting requirements could also subject us to sanctions and/or investigations by the SEC, The Nasdaq Global Select Market or other regulatory authorities.

Furthermore, shareholder activism, the current political environment and the current high level of government intervention and regulatory reform may lead to substantial new regulations and disclosure obligations, which may lead to additional compliance costs and impact the manner in which we operate our business in ways we cannot currently anticipate. Our management and other personnel will need to devote a substantial amount of time to these compliance initiatives. Moreover, any new regulations or disclosure obligations may increase our legal and financial compliance costs and will make some activities more time-consuming and costly.

Our share price is volatile and may be influenced by numerous factors that are beyond our control.


A low share price and low market valuation may make it difficult to raise sufficient additional cash due to the significant dilution to current stockholders.shareholders. Market prices for shares of biotechnology and biopharmaceutical companies such as ours are often volatile. Factors such as clinical and regulatory developments regarding our products or processes, developments regarding potential or future third-party collaborators, announcements of technological innovations, new commercial products, patents, the

development of proprietary rights by us or by others or any litigation relating to these rights, regulatory actions, general conditions in the biotechnology and pharmaceutical industries, failure to meet analysts’ expectations, publications, financial results or public concern over the safety of biopharmaceutical and biotechnological products, economic conditions in the United States and other countries, terrorism and other factors could have a significant effect on the share price for our shares of common stock. Any setback or delay in the clinical development of our programs could result in a significant decrease in our share price. In recent years the stock of other biotechnology and biopharmaceutical companies has experienced extreme price fluctuations that have been unrelated to the operating performance of the affected companies. There can be no assurance that the market price of our shares of common stock will not experience significant fluctuations in the future, including fluctuations that are unrelated to our performance. These fluctuations may result due to macroeconomic and world events, national or local events, general perception of the biotechnology industry or to a lack of liquidity. In addition, other biotechnology companies'companies’ or our competitors’ programs could have positive or negative results that impact their stock prices and their results or experience stock price fluctuations that could have a positive or negative impact on our stock price, regardless whether such impact is direct or not.


StockholdersShareholders may not agree with our business, scientific, clinical and financial strategy, including additional dilutive financings, and may decide to sell their shares or vote against such proposals. Such actions could materially impact our stock price. In addition, portfolio managers of funds or large investors can change or change their view on us and decide to sell our shares. These actions could have a material impact on our stock price. In order to complete a financing, or for other business reasons, we may elect to consolidate our shares of common stock. Investors may not agree with these actions and may sell our shares. We may have little or no ability to impact or alter such decisions.


*Our principal stockholders control the majority of our shares, and their actions may significantly influence matters submitted to our stockholders for approval and our share price.

Based on the information availableChanges in tax laws or regulations that are applied adversely to us as of September 30, 2017,or our stockholders and their affiliates who owned more than 5% of our outstanding common stock collectively owned 52% of our outstanding common stock. Baker Bros. Advisors, L.L.C. ("Baker Brothers") and Boxer Capital, LLC (“Boxer Capital”) and their affiliates collectively own 28% of our outstanding common stock. In addition, in conjunction with certain financing transactions, we granted to Baker Brothers and Boxer Capital each the right to nominatefuture potential customers may have a member of our Board of Directors and the right to appoint an observermaterial adverse effect on our Boardbusiness, cash flow, financial condition or results of Directors.

New income, sales, use or other tax laws, statutes, rules, regulations or ordinances could be enacted at any time, which could adversely affect our business operations and Boxer Capital mayfinancial performance. Further, existing tax laws, statutes, rules, regulations or ordinances could be interpreted, changed, modified or applied adversely to us. The Biden Administration and Congress have significant influence over matters submitted to our stockholders for approval, including the election and removal of directors and the approval of any merger, consolidation, or sale of all or substantially all of our assets. Furthermore, asproposed various U.S. federal tax law changes, which if enacted could have a thinly traded stock, if Baker Brothers, Boxer Capital or any other of our major stockholders determine to exit from the industry or from their holdings in us, for whatever reason, thematerial impact on our share pricebusiness, cash flows, financial condition or results of operations. Furthermore, it is uncertain if and to what extent various states will conform to federal tax laws. Future tax reform legislation could be detrimental overhave a prolonged periodmaterial impact on the value of time.our deferred tax assets, could result in significant one-time charges, and could increase our future U.S. tax expense.


Future sales and issuances of our common stock or rights to purchase common stock, including pursuant to our equity incentive plans, could result in additional dilution of the percentage ownership of our stockholdersshareholders and could cause our stock price to fall.


We expect that significant additional capital will be needed in the future to continue our planned operations. To the extent we raise additional capital by issuing equity securities, our stockholdersshareholders may experience substantial dilution. We may sell common stock, convertible securities or other equity securities in one or more transactions at prices and in a manner we determine from time to time. If we sell common stock, convertible securities or other equity securities in more than one transaction, investors may be materially diluted by subsequent sales. These sales may also result in material dilution to our existing stockholders,shareholders, and new investors could gain rights superior to our existing stockholders.shareholders.


Pursuant to our 2013 Equity Incentive Plan ("the 2013 Plan"), and our 2013 Employee Stock Purchase Plan ("the ESPP"(the “ESPP”), our management is authorized to grant stock options, restricted stock units and other equity-based awards to our employees, directors and consultants, and to sell our common stock to our employees, respectively. Pursuant to the inducement plan, the Board of Directors is authorized to grant stock options, restricted stock units and other equity-based awards to new employees who satisfy the standards for inducement grants in accordance with the Nasdaq Stock Market LLC listing rules. Any increase in the number of shares outstanding as a result of the exercise of outstanding options, the vesting or settlement of outstanding stock awards, or the purchase of shares pursuant to the ESPP will cause our stockholdersshareholders to experience additional dilution, which could cause our stock price to fall.

Our ability to use our U.S. net operating loss carryforwards and certain other tax attributes may be limited.

Under Section 382 of the Internal Revenue Code of 1986, as amended ("the Code"), if a corporation undergoes an “ownership change,” generally defined as a greater than 50% change (by value) in its equity ownership over a three year period, the corporation’s ability to use its pre-change U.S. net operating loss carryforwards ("NOLs"), and other pre-change U.S. tax attributes (such as research tax credits) to offset its post-change income may be limited. We may have experienced an ownership change based on past financing transactions and may experience ownership changes in the future as a result of subsequent shifts in our stock ownership. As a result, if we earn net taxable income, our ability to use our pre-change U.S. net operating loss

carryforwards to offset U.S. federal taxable income may be subject to limitations, which could potentially result in increased future tax liability to us. In addition, at the state level, there may be periods during which the use of NOLs is suspended or otherwise limited, which could accelerate or permanently increase state taxes owed.

Because we do not anticipate paying any cash dividends on our common stock in the foreseeable future, capital appreciation, if any, would be our stockholders’ only source of gain.

We have never declared or paid any cash dividends on our common shares, and we currently expect that earnings, if any, and cash flow will primarily be retained and used in our operations, including servicing any debt obligations we may have now or in the future. Accordingly, although we do not anticipate paying any dividends in the foreseeable future, we may not be able to generate sufficient cash flow in order to allow us to pay future dividends on, or make any distributions with respect to our common stock. As a result, capital appreciation, if any, of our common stock would be our stockholders’ sole source of gain on their investment in our common stock for the foreseeable future.

ITEM 5. Other Information

JOBS Act

In April 2012, the JOBS Act was enacted. Section 107 of the JOBS Act provides that an emerging growth company can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. Thus, an emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have irrevocably elected not to avail ourselves of this extended transition period and, as a result, we will adopt new or revised accounting standards on the relevant dates on which adoption of such standards is required for other companies. We are in the process of evaluating the benefits of relying on other exemptions and reduced reporting requirements provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, as an “emerging growth company,” we intend to rely on certain of these exemptions, including without limitation with respect to, (1) providing an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act and (2) complying with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements, known as the auditor discussion and analysis. We will remain an emerging growth company until the earliest of (1) the end of the fiscal year in which the market value of our common stock that is held by non-affiliates exceeds $700 million as of the end of the second fiscal quarter, (2) the end of the fiscal year in which we have total annual gross revenue of $1 billion or more during such fiscal year, (3) the date on which we issue more than $1 billion in non-convertible debt in a three-year period, or (4) December 31, 2018.
