Summary of Risk Factors
The risk factors described below are a summaryThis Quarterly Report on Form 10-Q also may include statistical and other industry and market data that we obtained from industry publications and research, surveys and studies conducted by third parties as well as our own estimates. All of the principal risk factors associated with an investmentmarket data used in us. These are not the only risks we face. Additional risks and uncertainties not presently known to us or that we presently deem less significant may also impair our business operations. You should carefully consider these risk factors, together with the risk factors set forth in Part I, Item 1A, “Risk Factors” of our 2020 Annual Report, which we refer to in Part II, Item 1A to this Quarterly Report on Form 10-Q as well asinvolves a number of assumptions and limitations, and you are cautioned not to give undue weight to such data. Industry publications and third-party research, surveys and studies generally indicate that their information has been obtained from sources believed to be reliable, although they do not guarantee the other reports and documents filed by us with the U.S. Securities and Exchange Commission,accuracy or the SEC. If anycompleteness of such information. Our estimates of the following risks occurs, our business, financial condition, and results of operations and future growth prospects could be materially and adversely affected, and the actual outcomes of matters as to which forward-looking statements are made in this report could be materially different from those anticipated in such forward-looking statements.
We have a history of operating losses, expect to incur significant and increasing operating losses in the future, and may never become profitable, or if we become profitable, we may not remain profitable.
We will need substantial additional funding, and if we are unable to raise capital when needed, we could be forced to delay, reduce or eliminate the development of eganelisib or future efforts to commercialize eganelisib. We cannot provide assurances that our estimates regarding expenses, future revenue, capital requirements and needs for additional financing are accurate.
We cannot provide assurances that our plans with respect to our ongoing and planned clinical trialspotential market opportunities for our product candidates will succeed, including the timing of these trialsinclude several key assumptions based on our industry knowledge, industry publications, third-party research and of the anticipated results.
We are dependentother surveys, which may be based on the success of eganelisib. If we are unable to complete the clinical development of, obtain marketing approval for or successfully commercialize eganelisib, either alone or with a collaborator, or if we experience significant delays in doing so, our business could be substantially harmed.
If clinical trials of eganelisibsmall sample size and may fail to satisfactorily demonstrate safety and efficacy to the U.S. Food and Drug Administration, or FDA, and other regulators,accurately reflect market opportunities. While we may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of eganelisib.believe that our internal assumptions are reasonable, no independent source has verified such assumptions.
Adverse events or undesirable side effects caused by, or other unexpected properties of, product candidates that we develop may be identified during development and could delay or prevent their marketing approval or limit their use.
The immuno-oncology industry is characterized by a rapidly changing competitive landscape and a crowded competitive field. We may be unable to compete with larger, more established entities in the field.
We are reliant on third parties, including collaborators, contract research organizations, manufacturers, and suppliers, to support our business. Should any such third party perform unsatisfactorily or unilaterally end our relationship, such outcome could have a material negative impact on our business and finances.
Our success depends substantially upon our ability to obtain, maintain and enforce intellectual property rights for the protection of eganelisib. We cannot guarantee the success of our intellectual property position and strategy.
The COVID-19 pandemic may materially and adversely affect our clinical trial operations, our future supply chain and our financial results.
We need to attract and retain highly skilled personnel; we may be unable to effectively manage growth with our limited resources.
Our common stock may have a volatile trading price and low trading volume.

Infinity Pharmaceuticals, Inc.
Notes to Condensed Consolidated Financial Statements
(Unaudited)
1. Organization
Infinity Pharmaceuticals, Inc., is a clinical-stage innovative biopharmaceutical company dedicated to developing novel medicines for people with cancer. As used throughout these unaudited, condensed consolidated financial statements, the terms “Infinity,” “we,” “us,” and “our” refer to the business of Infinity Pharmaceuticals, Inc., and its wholly-owned subsidiaries.
2. Basis of Presentation
These condensed consolidated financial statements include the accounts of Infinity and its wholly-owned subsidiaries. We have eliminated all significant intercompany accounts and transactions in consolidation.
The accompanying condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by generally accepted accounting principles for complete financial statements. In the opinion of management, all adjustments, consisting of normal recurring accruals and revisions of estimates, considered necessary for a fair presentation of the accompanying condensed consolidated financial statements have been included. Interim results for the three and nine months ended March 31,September 30, 2021 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2021.
The information presented in the condensed consolidated financial statements and related footnotes at March 31,September 30, 2021, and for the three and nine months ended March 31,September 30, 2021 and 2020, is unaudited, and the condensed consolidated balance sheet amounts and related footnotes at December 31, 2020 have been derived from our audited financial statements. For further information, please refer to the consolidated financial statements and accompanying footnotes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2020 filed with the U.S. Securities and Exchange Commission, or SEC, on March 16, 2021, which we refer to as our 2020 Annual Report on Form 10-K.
Liquidity
As of March 31,September 30, 2021, we had cash and cash equivalents of $106.8$90.1 million. We have primarily incurred operating losses since inception and have relied on our ability to fund our operations through collaboration and license arrangements or other strategic arrangements, as well as through the sale of stock.
We expect to continue to spend significant resources to fund the development and potential commercialization of eganelisib, also known as IPI-549, an orally administered, clinical-stage, immuno-oncology product candidate that reprograms macrophages through selective inhibition of the enzyme phosphoinositide-3-kinase-gamma, or PI3K-gamma, and to incur significant operating losses for the foreseeable future.
We believe that our existing cash and cash equivalents and available-for-sale securities at March 31,September 30, 2021 will be adequate to satisfy our forecasted operating needs for at least the next twelve months from the issuance date of these financial statements.
3. Significant Accounting Policies
Our significant accounting policies are described in Note 2, “Summary of Significant Accounting Policies,” in “Notes to Consolidated Financial Statements” in our 2020 Annual Report on Form 10-K.
Segment Information
We operate in 1 business segment, which focuses on drug development. We make operating decisions based upon the performance of the enterprise as a whole and utilize our consolidated financial statements for decision making.

Basic and Diluted Net Loss per Common Share
Basic net loss per share is based upon the weighted average number of common shares outstanding during the period. Diluted net loss per share is based upon the weighted average number of common shares outstanding during the period plus the effect of additional weighted average common equivalent shares outstanding during the period when the effect of adding such shares is dilutive. Common equivalent shares result from the assumed exercise of outstanding stock options and the exercise of outstanding warrants (the proceeds of which are then assumed to have been used to repurchase outstanding stock using the treasury stock method). and the vesting of restricted shares of common stock. In addition, the assumed proceeds under the treasury stock method include the average unrecognized compensation expense of stock options that are in-the-money. This results in the “assumed” buyback of additional shares, thereby reducing the dilutive impact of stock options. The two-class method is used for outstanding warrants as such warrants are considered to be participating securities, and this method is more dilutive than the treasury stock method. The following outstanding shares of common stock equivalents were excluded from the computation of net loss per share attributable to common stockholders for the periods presented because including them would have been antidilutive:

New Accounting Pronouncements
In June 2016, the Financial Accounting Standards Board, or FASB, issued Accounting Standard Update, or ASU, No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Statements, or ASU No. 2016-13, which requires that credit losses be reported using an expected losses model rather than the incurred losses model that is currently used, and it establishes additional disclosure requirements related to credit risks. For available-for-sale debt securities with expected credit losses, this standard now requires allowances to be recorded instead of reducing the amortized cost of the investment. In November 2019, the FASB subsequently issued ASU 2019-10, Financial Instruments—Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates, whereby the effective date of this standard for smaller reporting companies was deferred to annual reporting periods beginning after December 15, 2022, including interim periods within those annual reporting periods, and early adoption is still permitted. We are currently evaluating the impact of ASU No. 2016-13 on our consolidated financial statements and related disclosures.
In August 2020, the FASB issued ASU No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, or ASU No. 2020-06, which simplifies the guidance on an issuer’s accounting for convertible instruments and contracts in its own equity. The provisions of ASU No. 2020-06 are applicable for fiscal years beginning after December 15, 2023, with early adoption permitted no earlier than fiscal years beginning after December 15, 2020. We are currently evaluating the impact of ASU No. 2020-06 on our consolidated financial statements.

The fair value of the available-for-sale securities and cash and cash equivalents is based on the following inputs for both U.S. Treasury securities and U.S. government-sponsored enterprise obligations: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers and reference data including TRACE® reported trades.
There have been no changes to our valuation methods of available-for-sale securities during the threenine months ended March 31,September 30, 2021. We had 0no available-for-sale securities that were classified as Level 3 at any point during the threenine months ended March 31,September 30, 2021 or during the year ended December 31, 2020.
Warrant liability relates to potential future warrants that may be issued. The fair value of the warrant liability on the date of the commitment and on each re-measurement date for those warrants classified as liabilities was estimated using the Monte Carlo simulation model, which involves a series of simulated future stock price paths over the remaining life of the commitment. The fair value is estimated by taking the average of the fair values under each of many Monte Carlo simulations. The fair value estimate is affected by our stock price, as well as estimated future financing needs, including timing and sources of the financing and subjective variables including expected stock price volatility over the remaining life of the commitment and risk-free interest rate. Due to the nature of these inputs, the valuation of the warrants is considered a Level 3 measurement. The fair value of the warrant liability as of March 31, 2021andSeptember 30, 2021 and December 31, 2020 has been included in other liabilities on our condensed consolidated balance sheet. See Note 9 for further discussionsdiscussion of the accounting for the warrants.
The carrying amounts reflected in the condensed consolidated balance sheets for prepaid expenses and other current assets, other assets, accounts payable and accrued expenses and other current liabilities approximate their fair value due to their short-term maturities.

9. Liabilities Related to Sale of Future Royalties
HCR Agreement
In 2016, we and Verastem Inc., or Verastem, entered into an amended and restated license agreement, or the Verastem Agreement, under which we granted to Verastem an exclusive worldwide license in oncology indications for the research, development, commercialization, and manufacture of duvelisib, or Copiktra®, an oral, dual inhibitor of PI3K delta and gamma, and products containing duvelisib, which we refer to as Licensed Products. In September 2020, Verastem completed a disposition of its rights, title, and interest in and to duvelisib to Secura Bio, Inc., or Secura Bio, whereinwhereby Secura Bio assumed all liabilities and obligations under the Verastem Agreement. We now refer to the Verastem Agreement as the Secura Bio Agreement.
Secura Bio is obligated to pay us royalties on worldwide net sales of Licensed Products ranging from the mid-single digits to the high-single digits, a portion of which we are obligated to share with Takeda Pharmaceuticals Company Limited, or Takeda, as described in Note 11.
In March 2019, we entered into a royalty purchase agreement, or the HCR Agreement, with HealthCare Royalty Partners III, L.P., or HCR, providing for the acquisition by HCR of our interest in certain royalty payments based on worldwide annual net sales of Licensed Products under the Secura Bio Agreement for gross proceeds of $30.0 million, which is non-refundable. Under the HCR Agreement, HCR obtained the right to receive the royalty payments up to an agreed upon thresholds of royalties, the amount of which depends on when the aggregate royalties received by HCR reach specified thresholds. If the specified threshold has been met through royalty payments from Secura Bio or if we elect to make a payment to meet the threshold amount, the HCR Agreement will automatically terminate and all rights to the royalty stream under the HCR Agreement will revert back to us. If the specified threshold has not been achieved by June 30, 2025, the HCR Agreement will continue through the term of the Secura Bio Agreement.
1112

Table of Contents
We recognized the receipt of the $30.0 million payment from HCR, net of debt discount and issuance costs of approximately $2.4 million, as a liability. As the basis for our determination, we considered, in accordance with the relevant accounting guidance, the potential for the royalty stream to revert back to us if specified royalty thresholds hashave been met and our right to terminate the HCR Agreement by making a payment to achieve the threshold. We are not obligated to repay the proceeds received under the HCR Agreement. In order to determine the amortization of the liability, we are required to estimate the total amount of future net royalty payments to be made to HCR over the term of the HCR Agreement. The total threshold of net royalties to be paid, less the net proceeds received, will be recorded as interest expense over the life of the liability. We impute interest on the unamortized portion of the liability using the effective interest method. Interest and debt discount amortization expense is reflected as non-cash interest expense in the condensed consolidated statements of operations. Over the course of the HCR Agreement, the actual interest rate will be affected by the amount and timing of royalty revenue recognized and changes in forecasted royalty revenue. On a quarterly basis, we reassess the effective interest rate and adjust the rate prospectively as needed.
The following table shows the activity within the liability account for the threenine months ended March 31,September 30, 2021:

Less: current portion(895)(909)
Liability related to sale of future royalties, net, less current portion$27,76527,330 
As royalties are due to HCR by Secura Bio, the balance of the recognized liability will be effectively repaid over the life of the HCR Agreement. There are a number of factors that could materially affect the amount and timing of royalty payments from Secura Bio, none of which are within our control.
BVF Agreement
On January 8, 2020, or the BVF Closing Date, we entered into a funding agreement, or the BVF Funding Agreement, with BVF Partners, L.P., or BVF, and Royalty Security, LLC, a wholly-owned subsidiary of BVF, or the Buyer. BVF was subsequently replaced as a party to the BVF Funding Agreement with Royalty Security Holdings, LLC. The BVF Funding Agreement provides for the acquisition by the Buyer of our interest in all royalty payments based on worldwide annual net sales of a clinical-stage product candidate IPI-926, or patidegib, part of the hedgehog inhibitor program we licensed to PellePharm Inc., or PellePharm, in 2013, or the BVF Licensed Product, excluding relevant Trailing Mundipharma Royalties, as defined in Note 11, which is related to patidegib. We refer to all BVF Licensed Product royalties owed to us less Trailing Mundipharma Royalties as the Royalty or Royalties. Such Royalties are owed to us pursuant to the PellePharm Agreement, as defined in Note 11, entered into by and between us and PellePharm. The Buyer and BVF are affiliates of Biotechnology Value Fund, L.P., which beneficially owned approximately 30% of our common stock at the time of the transaction. Effective February 17, 2021, Biotechnology Value Fund, L.P. is no longer considered our related party.
Pursuant to the BVF Funding Agreement, we received a non-refundable payment of $20.0 million, or the Upfront Purchase Price, less certain transaction expenses. We transferred to the Buyer (i) the Royalty, (ii) the PellePharm Agreement (subject to our rights to milestone payments and rights to equity in PellePharm under the PellePharm Agreement), and (iii) certain patent rights established in the BVF Funding Agreement, with (i), (ii), and (iii) together referred to as Transferred Assets. We preserved our rights under the PellePharm Agreement to receive potential regulatory, commercial, and success-based milestone payments. We have the option to terminate the BVF Funding Agreement by purchasing 100% of the outstanding equity interests of the Buyer under specified terms for a specified amount under the BVF Funding Agreement through January 8, 2023. In addition, the BVF Funding Agreement may be terminated by mutual written agreement ofbetween us and the Buyer.
1213

Table of Contents
We recognized the proceeds received under the BVF Funding Agreement as a related party liability that will be amortized using the effective interest method over the life of the arrangement. We recorded the receipt of the $20.0 million Upfront Purchase Price as a liability, net of debt issuance costs of approximately $0.4 million and warrant liability of $0.3 million. The related party liability has been reclassified to liabilities related to sale of future royalties since Biotechnology Value Fund, L.P. is no longer considered our related party. We are not obligated to repay the proceeds received under the BVF Funding Agreement. In order to determine the amortization of the liability, we are required to estimate the total amount of potential future net royalty payments to be made by PellePharm to the Buyer over the term of the BVF Funding Agreement. The total estimated net royalties to be paid, less the net proceeds received, will be recorded as interest expense over the life of the liability. Interest and debt discount amortization expense is reflected as non-cash related party interest expense as of December 31, 2020 and non-cash interest expense as of March 31,September 30, 2021 in our condensed consolidated statements of operations.operations and comprehensive loss. Over the course of the BVF Funding Agreement, the actual interest rate will be affected by the amount and timing of royalty revenue recognized, if any, and changes in forecasted royalty revenue. There are a number of factors that could materially affect the amount and timing of royalty payments from PellePharm, none of which are within our control. On a quarterly basis, we will reassess the effective interest rate and adjust the rate prospectively as needed.
The following table shows the activity within the liability account for the threenine months ended March 31,September 30, 2021:

Liability related to sale of future royalties, net - ending balance$21,56621,579 
For so long as we have not exercised an option to repurchase the Buyer’s equity interest under the BVF Funding Agreement, (a) if, during the 36-month period following the BVF Closing Date, we issue a specified number of shares of our common stock, which we refer to as the Warrant Threshold, and (b) any shares in excess of the Warrant Threshold are issued for consideration to us of less than $3.75 per share (as adjusted for any stock splits, reverse stock splits or other similar recapitalization events), or the Threshold Price, then we are obligated to issue to BVF warrants to purchase a number of shares of our common stock. Such warrants would equal 50% of the number of qualifying shares at an exercise price equal to 1.5 times the price per share of such qualifying shares issued. The requirement to issue warrants to BVF does not apply to certain issuances of our common stock. As of March 31,September 30, 2021, the Warrant Threshold has been met and any future qualifying shares of our common stock issued below the Price Threshold will result in warrants to purchase our common stock to be issued to BVF. NaNNo warrants have been issued to BVF as of March 31,September 30, 2021.
We determined that the commitment to issue warrants represents a freestanding financial instrument and accounted for it as a liability as of the BVF Closing Date. The fair value of the warrant liability was estimated using the Monte Carlo simulation model. The fair value of the warrant liability as of March 31,September 30, 2021 has been included in other liabilities on our condensed consolidated balance sheet. We will re-measure the warrant liability at each reporting date. Changes in fair value of the warrant liability isare included in investment and other income (expense) onin our condensed consolidated statementstatements of operations and comprehensive loss. See Note 6 for further discussions of the fair value of the warrants.
10. Commitments and Contingencies
On April 5, 2019, we entered into a lease agreement, or the Lease, with Sun Life Assurance Company of Canada, or the Landlord, effective April 3, 2019, or the Commencement Date, for the lease of approximately 10,097 square feet of office space at 1100 Massachusetts Avenue, Cambridge, Massachusetts, or the Leased Premises. The term of the Lease commenced on the Commencement Date and expires on August 1, 2024, or the Expiration Date, approximately five years after the Rent Commencement Date as describeddefined below.
Beginning August 1, 2019, or the Rent Commencement Date, the total base rent of the Lease will bewas $47,961 per month and will increaseincreases by approximately 3% on each anniversary of the Rent Commencement Date until the Expiration Date. In addition to the base rent, we are also responsible for our share of the operating expenses, insurance, real estate taxes and certain capital costs, and we are responsible for utilitiesutility expenses in our premises,the Leased Premises, all in accordance with the terms of the Lease. Pursuant to the terms of the Lease, we provided a security deposit in the form of a letter of credit in the initial amount $300,000, which may bewas reduced to $150,000 over timeduring the three months ended September 30, 2021 in accordance with the terms of the Lease.

11. Strategic Agreements
We have worldwide development and commercialization rights to eganelisib, subject to certain obligations to our licensor, Takeda Pharmaceutical Company Limited, or Takeda, as described in more detail below. Additionally, we are obligated to pay Mundipharma International Corporation Limited, or Mundipharma, and Purdue Pharmaceutical Products L.P., or Purdue, a 4% royalty in the aggregate on worldwide net sales of products that were previously subject to our strategic alliance with Mundipharma and Purdue that was terminated in 2012. Such products include eganelisib; duvelisib, the PI3K delta and gamma inhibitor that we licensed to Verastem in 2016, andthe rights to which Verastem sold its interest in these rights to Secura Bio in 2020; and IPI-926, or patidegib, part of the hedgehog inhibitor program we licensed to PellePharm in 2013. We refer to such royalties as Trailing Mundipharma Royalties. After Mundipharma and Purdue have recovered approximately $260.0 million in royalty payments from all products that were previously subject to the strategic alliance, which represents the funding paid to us for research and development services performed by us under this strategic alliance, the Trailing Mundipharma Royalties will be reduced to a 1% royalty on net sales in the United States of such products.
PellePharm
In June 2013, we entered into a license agreement with PellePharm, under which we granted PellePharm exclusive global development and commercialization rights to our hedgehog inhibitor program, including patidegib, a clinical-stage product candidate.patidegib. We refer to our license agreement with PellePharm as the PellePharm Agreement and products covered by the PellePharm Agreement as Hedgehog Products. We assessed this arrangement in accordance with Accounting Standard Codification 606 and concluded that at the date of contract inception there was only one performance obligation, consisting of the license, which was satisfied at contract inception.
Under the PellePharm Agreement, PellePharm is obligated to pay us up to $9.0 million in remaining regulatory and commercial-based milestone payments through the first commercial sale of a Hedgehog Product. PellePharm is also obligated to pay us up to $37.5 million in success-based milestone payments upon the achievement of certain annual net sales thresholds, as well as a share of certain revenue received by PellePharm in the event that PellePharm sublicenses its rights under the PellePharm Agreement and tiered royalties on annual net sales of Hedgehog Products subject to specified conditions. The remaining milestones have not been recognized as they represent variable consideration that is constrained. In making this assessment, we considered numerous factors, including the fact that achievement of the milestones is outside of our control and contingent upon the future success of clinical trials, PellePharm’s actions, and the receipt of regulatory approval. As the single performance obligation was previously satisfied, all regulatory and commercial-based milestones will be recognized as revenue in full in the period in which the constraint is removed. Any consideration related to sales-based milestone payments, including royalties, will be recognized when the related sales occur as these amounts have been determined to relate predominantly to the license granted to PellePharm and therefore are recognized at the later of when the performance obligation is satisfied or the related sales occur.
PellePharm is also obligated to pay us tiered royalties on annual net sales of Hedgehog Products, which are subject to reduction after a certain aggregate funding threshold has been achieved. On January 8, 2020, we entered into the BVF Funding Agreement, as further described in Note 9, pursuant to which we sold our interest in all royalty payments based on worldwide annual net sales of the BVF Licensed Product excluding Trailing Mundipharma Royalties related to patidegib.
Takeda
In July 2010, we entered into a development and license agreement with Intellikine, Inc., or Intellikine, under which we obtained rights to discover, develop and commercialize pharmaceutical products targeting the gamma and/or delta isoforms of PI3K, including eganelisib and duvelisib. In January 2012, Intellikine was acquired by Takeda. In December 2012, we amended and restated our development and license agreement with Takeda and further amended the agreement in July 2014, September 2016, July 2017, and March 2019. We refer to the amended and restated development and license agreement, as amended, as the Takeda Agreement.

Duvelisib
Pursuant to the Takeda Agreement, prior to March 4, 2019, we were obligated to share equally with Takeda all revenue arising from certain qualifying transactions for duvelisib, including the Secura Bio Agreement, subject to certain exceptions including revenue we receive as reimbursement for duvelisib research and development expenses. By entry into a fourth amendment onOn March 4, 2019, we entered into the fourth amendment to the Takeda Agreement, or the Takeda Amendment. Pursuant to the Takeda Amendment, Takeda consentedagreed (i) to the sale of certain royalty payments based on worldwide annual net sales of Licensed Products under the Secura Bio Agreement to HCR, and agreed(ii) to forego its rights to an equal share of the royalties due from Secura Bio during the term of the HCR Agreement, and agreed(iii) not to seek any payment from HCR with respect to the royalties owed to Takeda. In exchange,As consideration for the Takeda Amendment, we paid Takeda $6.7 million representing 25% of the $30.0 million in gross proceeds we received from the closing of the HCR Agreement, net of 25% of the expenses incurred by us in connection with the HCR Agreement. In addition, we agreed to pay Takeda 25% of the royalties that would have been payable to us by Secura Bio but for the consummation of the HCR Agreement, which we refer to as the Interim Obligation. During each of the threenine months ended March 31,September 30, 2021 and 2020, we recognized $0.1$0.2 million during both periods, inof Interim Obligation amounts owed to Takeda as royalty expense.
We have the right to extinguish the Interim Obligation by payment to Takeda of an amount equal to (i) the $6.7 million payment multiplied by a specified multiple corresponding to the time period in which such extinguishing payment is made, minus (ii) any payments made to Takeda pursuant to the Interim Obligation. The Interim Obligation shall expire upon the termination of the HCR Agreement and the reversion of related royalties to us, , at which time our obligations to share equally with Takeda the royalties payable under the Secura Bio Agreement equally with Takeda shall be reinstated.
Eganelisib
Pursuant to the Takeda Agreement, we are obligated to pay Takeda up to $3.0 million in remaining success-based development milestone payments and up to $165.0 million in remaining regulatory and commercial-based milestone payments for 1 product candidate other than duvelisib, which could be eganelisib.

Business Overview
We are a clinical-stage innovative biopharmaceutical company dedicated to developing novel medicines for people with cancer. We combine proven scientific expertise with a passion for developing novel small molecule drugs that target disease pathways for potential applications in oncology. We are focused on advancing eganelisib, also known as IPI-549, an orally administered, clinical-stage, immuno-oncology product candidate that reprograms macrophages through selective inhibition of the enzyme phosphoinositide-3-kinase-gamma, or PI3K-gamma. We have retained worldwide development and commercialization rights to eganelisib, and we believe eganelisib is the only selective inhibitor of PI3K-gamma being investigated in clinical trials.
2021 Public Offering
On February 11, 2021, we entered into a purchase agreement with Piper Sandler & Co., as representative of the underwriters named therein, pursuant to which we issued and sold to the underwriters in an underwritten public offering an aggregate of 24,150,000 shares of our common stock, including 3,150,000 shares of common stock sold in connection with the exercise in full of a 15% over-allotment option by the underwriters. The public offering price was $3.80 per share. The gross proceeds to us from this offering were approximately $91.8 million. After underwriting discounts and commissions and estimated offering expenses, we received net proceeds from the offering of approximately $85.8 million.
Clinical Development Program
We are conducting the following clinical trials investigating eganelisib in solid tumors:
MARIO-3 (MAcrophage Reprogramming in Immuno-Oncology-3)
MARIO-3 is a multi-arm Phase 2 study designed to evaluate eganelisib in the front-line setting for triple negative breast cancer, or TNBC, and front-line renal cell carcinoma, or RCC. The TNBC cohort is evaluating eganelisib in combination with atezolizumab, an anti-PD-L1 monoclonal antibody also known as Tecentriq®Tecentriq®, and nab-paclitaxel, an albumin-bound chemotherapy drug also known as Abraxane®, in up toapproximately 60 patients with unresectable locally advanced or metastatic front-line TNBC. The RCC cohort is evaluating eganelisib in combination with atezolizumab and bevacizumab, also known as Avastin®, in up toapproximately 30 patients with front-line RCC. We entered into a clinical supply agreement with F. Hoffmann-La Roche Ltd., or Roche, under which Roche has agreed to supply atezolizumab and bevacizumab for our use in MARIO-3. In August 2021, Roche voluntarily withdrew its accelerated approval in the United States for atezolizumab in combination with nab-paclitaxel for patients with PD-L1-positive metastatic TNBC after IMpassion131, Roche’s post marketing study evaluating atezolizumab and paclitaxel in TNBC patients, did not meet its primary endpoint. Roche announced that its decision was made in consultation with the U.S. Food and Drug Administration, based on the agency’s assessment of the current metastatic TNBC treatment landscape, and in accordance with the requirements of the accelerated approval program, and was unrelated to efficacy or safety associated with atezolizumab. Roche’s decision does not alter our clinical rationale for MARIO-3, and we do not expect it to have any impact on the conduct of MARIO-3. The combination of atezolizumab and nab-paclitaxel for treatment of patients with PD-L1 positive metastatic TNBC remains approved in multiple countries outside of the U.S.
In October 2021, Bristol Myers Squibb, or BMS, announced worldwide manufacturing-related constraints to the supply of nab-paclitaxel, which we use in the TNBC cohort of MARIO-3. BMS has stated that current inventory and distribution are being allocated by BMS to minimize potential impact to patient supply, and BMS has also indicated that at this time it anticipates limited supply and temporary allocations. We are actively working with BMS and our supply and distribution partners to identify and mitigate any potential impact this shortage may have on MARIO-3. We expect our current supply of nab-paclitaxel, orders for which are placed on a rolling basis, to last into the first quarter of 2022, and BMS intends to provide an update regarding the duration of supply constraints in mid-November 2021. For further discussion regarding risks related to the nab-paclitaxel shortage, please refer to the risk factor entitled “We are dependent on the success of eganelisib, our only product candidate, which remains subject to clinical testing and regulatory approval. If we are unable to initiate or complete clinical development of, obtain marketing approval for or successfully commercialize eganelisib, either alone or with a collaborator, or if we experience significant delays in doing so, our business could be substantially harmed,” found in Item 1A, “Risk Factors,” to this Form 10-Q.

On December 9, 2020,July 27, 2021, we presented initialupdated data at the 2020 San Antonio Breast Cancer Symposium, or SABCS, from the TNBC cohort of MARIO-3. As of the November 6, 2020 cut-offJune 26, 2021 data cutoff date, 43 patients were enrolled in the study with 38 patients evaluable for SABCS, we had enrolled 20 of 60efficacy. We refer to patients with tumors that test negative for a protein called programmed-death ligand 1, or PD-L1, at baseline as “PD-L1(-) patients” and the seven most recently enrolled patients remained on treatment but had not yet had their first assessment.those with tumors that test positive for PD-L1 at baseline as “PD-L1(+) patients.” The poster presentedMARIO-3 data include the following findings among the 13findings:
86.8% (33/38) of evaluable patients:
100% (13/13)patients demonstrated tumor reduction;reduction.

SafetyIn PD-L1(-) patients, PFS was extended as compared to benchmark data showed that the triple combination treatment with eganelisib,for atezolizumab and nab-paclitaxel alone, increasing from 5.6 months to 7.3 months (3.5, NA).
In PD-L1(+) patients, PFS was in line with expectations of the component drugs with noextended as compared to benchmark data for atezolizumab and nab-paclitaxel alone, increasing from 7.5 to 11.2 months (5.3, 11.2).
MARIO-3 did not demonstrate any new or additive or new safety signals.signals compared to benchmark trials. The most common ≥ Grade 3 treatment-emergenttreatment emergent adverse events (TEAEs), all causality, were decreased neutrophil count (21.4%nausea (51.2%), fatigue (48.8%), alopecia (32.6%), diarrhea (14.3%(32.6%), rash maculo-papular (30.2%), increased ALT (27.9%, one Grade 4, no Grade 5), and rash (14.3%)increased AST (25.6%, one Grade 4, no Grade 5). OnlyNo Hy’s Law or Grade 5 AEs were reported, and only one patient (7.1%permanently discontinued study treatment due to an elevated liver function test.“Hy’s Law” describes a set of criteria that, when present, indicate that a patient is experiencing a drug-induced liver injury with a 10% to 50% chance of mortality or need for a liver transplant.
Quantification across 11 paired tumor biopsies showed increased immune activation and decreased immune suppression including an increase in CD8+ T cells, activated T cells, and anti-tumor M1 macrophages and a decrease in tumor cells and pro-tumor M2 macrophages, resulting in an increase in the M1:M2 ratio.
Analyses of paired tumor biopsy data of the eight PD-L1(-) patients showed that five patients converted to PD-L1(+) status two months after treatment and the other three patients showed increased PD-L1 expression. None of these eight PD-L1(-) patients experienced ≥ Grade 3 ALT/AST increase, and this patient had a Grade 3 elevation.disease progression.
We expect to complete enrollment forpresent updated safety and efficacy data from the MARIO-3 TNBC cohort inat the second half ofSan Antonio Breast Cancer Symposium (SABCS) Annual Meeting, December 7-10, 2021, and expectare on track to present updated data mid-year and in the fourth quarter, including increased patient numbers and early durability data.
Enrollment is complete in the RCC cohort and we expect to present data from the RCC cohort in the first half of 2022.enroll approximately 60 patients by year end.
MARIO-275
MARIO-275 is our global, randomized, placebo-controlled Phase 2 study evaluating the effect of adding eganelisib to nivolumab, also known as Opdivo®, in checkpoint-naïve advanced urothelial cancer, or UC, patients whose cancer has progressed or recurred following treatment with platinum-based chemotherapy. Nivolumab is an immune checkpoint inhibitor therapy commercialized by Bristol Myers Squibb Company, or BMS, that targets programmed death receptor 1, or PD-1, a checkpoint protein that helps regulate the body’s immune system.
On July 27, 2021, we presented updated data from MARIO-275. The data from the 49 patients enrolled in the trial include the following findings:
Median overall survival (mOS) in the intent to treat population was 15.4 months (6.2, NE) on the eganelisib plus nivolumab combination arm as compared to 7.9 months (2.3, NE) on the control arm of nivolumab alone with a hazard ratio (HR) 0.62 (0.28, 1.36), reflecting a 38% lower probability of death.
In a one-year landmark analysis of the ITT population, 59% of patients in the nivolumab combination were alive, compared to 32% in the nivolumab control arm.
The mOS in PD-L1(-) patients was 15.4 months (4.7, NE) on the eganelisib plus nivolumab arm versus 7.9 months (1.9, NE) on the nivolumab control arm with an HR 0.60 (0.21, 1.71), reflecting a 40% lower probability of death.
In a one-year landmark analysis of patients with PD-L1(-) tumors, 54% on the eganelisib plus nivolumab combination remained alive, compared to 17% in the nivolumab control arm.

Table of Contents
The combination of eganelisib and nivolumab was generally well tolerated at the 30 mg once daily dose. The most common TEAEs across all doses, all causality, were pyrexia (33.3%), decreased appetite (30.3%), pruritus (27.3%), asthenia (27.3%), rash (27.3%), disease progression (27.3%) and increased alanine aminotransferase (24.2%); and the most common ≥Grade 3 TEAEs across all doses, all causality, were disease progression (27.3%), anemia (12.1%), and hepatic AEs including hepatotoxicity (15.2%), increased ALT (12.1%), and increased AST (12.1%) with no Hy’s Law. No Grade 5 AEs were reported.
Gene expression studies from peripheral blood, followed by gene set enrichment analysis using Hallmark gene signature sets, show the pro-inflammatory interferon gamma and interferon alpha pathways were the most significantly enriched pathways in the combination arm when comparing Day 15 to baseline, regardless of baseline PD-L1 status, with higher enrichment scores and lower p values than on the control arm. This data is consistent with eganelisib’s mechanism of action, which decreases immune suppression and increases immune activation.
On February 11, 2021, we presented data from MARIO-275 at the American Society of Clinical Oncology Genitourinary Cancers Symposium, or ASCO GU, from MARIO-275.GU. The greatest benefit of the combination of eganelisib and nivolumab was observed in the patient population (n=23) with tumors expressing low levels of programmed death ligand 1, or PD-L1, with improvement over nivolumab monotherapy (n=7) in overall response rate, or ORR (26% vs. 14%); disease control rate, or DCR (57% vs. 14%); and best responses of complete response, or CR (9% vs. 0%), and stable disease, or SD (30% vs. 0%). Of patients with PD-L1 low patientstumors in the combination arm, 58% (11 of 19) achieved a reduction in tumor burden, compared to 17% (1 of 6) in the nivolumab plus placebo arm. Additionally, patients with PD-L1 low patientstumors demonstrated an extended progression free survival, or PFS, with a hazard ratio of 0.54, which reflects a 46% reduction in probability of disease progression (median PFS of 9.1 weeks on combination arm versus 7.9 weeks on the nivolumab plus placebo arm).
The combination of eganelisib and nivolumab was well tolerated at a 30 mg once daily, or QD, dose, which was reduced from the initial dose of 40 mg QD to address liver enzyme elevations reported at a planned review by the Independent Data Monitoring Committee, or IDMC, for the study. In May 2020, we voluntarily paused enrollment in the study and implemented this dose reduction, and in September 2020, the IDMC supported further exploration of the combination therapy following the successful implementation of the dose reduction. The median average daily dose of eganelisib in the study was 31.5 mg. The most common treatment emergent adverse events, or TEAEs, were pyrexia (33%), decreased appetite (33%), pruritus (24%), rash (24%), and increased alanine aminotransferase (24%). The most common ≥ Grade 3 TEAEs across all doses, all causality, were disease progression (24.2%), hepatotoxicity (24.2%), increased ALT (12.1%), and increased AST (12.1%). No Hy’s Law cases were observed and no Grade 5 TEAEs were reported. “Hy’s Law” describes a set of criteria that, when present, indicate that a patient is experiencing a drug-induced liver injury with a 10% to 50% chance of mortality (or need for a liver transplant).
Based on the data from MARIO-275, we are planning a new registration-enabling study and will not re-open enrollment in MARIO-275.

MARIO-1
Enrollment is complete in MARIO-1, our Phase 1/1b clinical study designed to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamics, and activity for eganelisib — both as a monotherapy and in combination with nivolumab — in 224 patients with advanced solid tumors. The study includes a dose escalation portion and a combination therapy expansion portion evaluating patients dosed at 40 mg QD of eganelisib in combination with the standard regimen of nivolumab in the following forms of cancer: TNBC, melanoma, squamous cell carcinoma of the head and neck, or SCCHN, non-small cell lung cancer, mesothelioma, adrenocortical carcinoma, and those with high baseline blood levels of MDSCs. Safety data demonstrates that eganelisib combined with nivolumab is well tolerated at all doses tested, up to the recommended combination therapy expansion dose of eganelisib at 40 mg QD plus the standard regimen of nivolumab. No maximum tolerated dose was determined, and there have been no treatment-related deaths.
We provided updated data for the melanoma expansion cohort and SCCHN expansion cohort at the 2021 Annual Meeting of the Society for Immunotherapy of Cancers, or SITC. Data from both cohorts shows evidence of clinical activity in patients not expected to benefit from checkpoint inhibitor, or CPI, monotherapy due to immediate prior progression on a CPI. Safety data from both cohorts indicates the combination therapy was generally well tolerated and associated with a favorable safety profile.
The melanoma cohort achieved a DCR of 52.6% (10 of 19 patients) and an ORR of 21.1% (4 of 19 patients) in patients with immediate prior progression on CPI therapy and two or fewer prior lines of therapies, and reversal of progressive disease in patients with immediate prior treatment with anti-PD1/PD-L1 therapy was observed. Translational data validate the on-mechanism eganelisib effect of decreased immune suppression as measured by MDSC levels, and increased immune activation as measured by increased levels of previously exhausted T cells.
The SCCHN cohort achieved a DCR of 40% (4 of 10 evaluable patients) and an ORR of 20% (2 of 10 evaluable patients) in patients with immediate prior progression on CPI therapy and two or fewer prior lines of therapy, and reversal of progressive disease with immediate prior treatment with an anti-PD1/PD-L1 therapy was observed.
Arcus Collaboration Trial
In December 2020, Arcus Biosciences, Inc., or Arcus, presented data at SABCS from the Phase 1/1b clinical study collaboration between Infinity and Arcus on ARC-2, a study designed to evaluate each company’s respective drug candidates in up to 40 patients with previously treated, advanced TNBC and ovarian cancer. The ARC-2 SABCS data showed that a novel triple-combination regimen of eganelisib in combination with etrumadenant, Arcus’s dual adenosine receptor antagonist, and liposomal doxorubicin chemotherapy, also known as Doxil®, lead to a meaningfulan increase in response in TNBC patients. The companies have determined that these findings are sufficient to guide their internal development plans and have decided to close enrollment while allowing existing patients to remain on treatment.
Business Update Regarding COVID-19
In December 2019, a novel strain of coronavirus surfaced causing the respiratory disease COVID-19. This disease has spread worldwide and was deemed a “pandemic” by the World Health Organization on March 11, 2020. The following guidance regarding the impact of the COVID-19 pandemic on our business operations is highly uncertain and subject to change. We cannot know with certainty what the ultimate impact of the pandemic will be.
We are continuing to evaluate enrollment trends in our studies as well as the impact of COVID-19 on our clinical programs. Patients enrolled on MARIO-275, MARIO-3 and MARIO-1 have continued treatment and study visits with limited disruption to date, and we are working closely with trial sites to support the continued treatment of patients in compliance with study protocols. New patient screening and enrollment are being assessed on a case-by-case basis and are ongoing for the TNBC cohort in MARIO-3. ThereAlthough there is a severe worldwide shortage of the BMS drug nab-paclitaxel, which we use in combination with eganelisib and atezolizumab to treat MARIO-3 patients, this shortage is unrelated to COVID-19, and there are no anticipated disruptions to drug supply.supply due to COVID-19. The safety and well-being of our employees remains a top priority, and we are working to mitigate risk while minimizing disruptions through our work-from-home policy. We believe we are well suited to operate remotely as a clinically focused company.
Alliances, Collaborations, and Other Arrangements
We have primarily incurred operating losses since inception and will continue to fund our operations through collaboration and license arrangements or other strategic arrangements, as well as through the sale of securities or incurring debt, until such time as we are able to generate significant revenue from product sales, if ever. Such arrangements have provided access to breakthrough science, significant research and development support and funding, supply of clinical trial materials, and innovative drug development programs, all intended to help us realize the full potential of our product pipeline.

In July 2010, we entered into a development and license agreement with Intellikine, Inc., or Intellikine, under which we obtained rights to discover, develop and commercialize pharmaceutical products targeting the gamma and/or delta isoforms of PI3K, including eganelisib and duvelisib, or Copiktra®, an oral, dual inhibitor of PI3K delta and gamma. We licensed our rights related to the development of duvelisib to Verastem Inc., or Verastem, in 2016. In September 2020, Verastem completed a disposition of its rights, title, and interest in and to duvelisib to Secura Bio, Inc., or Secura Bio, wherein Secura Bio assumed all liabilities and obligations under the Verastem Agreement. We now refer to the Verastem Agreement as the Secura Bio Agreement. In January 2012, Intellikine was acquired by Takeda Pharmaceutical Company Limited, or Takeda. In December 2012, we amended and restated our development and license agreement with Takeda and further amended the agreement in July 2014, September 2016, July 2017, and March 2019. We refer to the amended and restated development and license agreement, as amended, as the Takeda Agreement. We are obligated to pay Takeda up to $3.0 million in remaining success-based development milestone payments and up to $165.0 million in remaining regulatory and commercialization success-based milestone payments, for one product candidate other than duvelisib, which could be eganelisib.
Financial Overview
Revenue
To date, all our revenue has been generated under collaboration agreements, including payments to us of upfront license fees, funding or reimbursement of research and development efforts, milestone payments if specified objectives are achieved, and/or royalties on product sales.
We recognize revenue when we transfer goods or services to customers in an amount that reflects the consideration that we expect to receive for those goods or services. These principles are applied using a five-step model: 1) identify the customer contract; 2) identify the contract’s performance obligations; 3) determine the transaction price; 4) allocate the transaction price to the performance obligations; and 5) recognize revenue when or as a performance obligation is satisfied. We evaluate all promised goods and services within a customer contract and determine which of those are separate performance obligations. This evaluation includes an assessment of whether the good or service is capable of being distinct and whether the good or service is separable from other promises in the contract. When a performance obligation is satisfied, we recognize as revenue the amount of the transaction price, excluding estimates of variable consideration that are constrained, that is allocated to that performance obligation. For contracts that contain variable consideration, such as milestone payments, we estimate the amount of variable consideration by using either the expected value method or the most likely amount method. In making this assessment, we evaluate factors such as the clinical, regulatory, commercial and other risks that must be overcome to achieve the milestone. Each reporting period we re-evaluate the probability of achievement of such milestones and any related constraints. We will include variable consideration, without constraint, in the transaction price to the extent it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved.
We recognize sales-based milestones and royalty revenue based upon net sales by the licensee of licensed products in licensed territories, and in the period the sales occur under the sales- and usage-based royalty exception when the sole or predominate item to which the royalty relates is a license to intellectual property.
In the event of an early termination of a collaboration agreement, any contract liabilities would be recognized in the period in which all our obligations under the agreement have been fulfilled.
Research and Development Expense
We are a drug development company. Our research and development expense has historically consisted primarily of the following:
compensation of personnel associated with research and development activities;
clinical testing costs, including payments made to contract research organizations;
costs of combination and comparator drugs used in clinical studies;
costs of manufacturing product candidates for preclinical testing and clinical studies;
costs associated with the licensing of research and development programs;
preclinical testing costs, including costs of toxicology studies;
fees paid to external consultants;
fees paid to professional service providers for independent monitoring and analysis of our clinical trials;
costs for collaboration partners to perform research and development activities, including development milestones for which a payment is due when achieved;

depreciation of equipment; and
allocated costs of facilities.
General and Administrative Expense
General and administrative expense primarily consists of compensation of personnel in executive, finance, accounting, legal and intellectual property, information technology infrastructure, corporate communications, and human resources functions. Other costs include facilities costs not otherwise included in research and development expense and professional fees for legal and accounting services.
Royalty Expense
Royalty expense represents the expense associated with amounts owed to third parties as a result of royalty revenue recognized and the amounts owed by us to Takeda in relation to the sale of future royalties.
Other Income and Expense
Other income and expense typically consist of interest earned on cash, cash equivalents and available-for-sale securities, non-cash interest expense, and changes in fair value of the warrant liability.
Critical Accounting Policies and Significant Judgments and Estimates
The discussion and analysis of our financial condition and results of operations is based on our condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of these financial statements requires us to make judgments, estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. On an ongoing basis, we evaluate our estimates, including those related to cumulative revenue related to variable consideration, accrued expenses, estimates of future net royalty payments used in the calculation of our liability related to the sale of future royalties, and assumptions in the valuation of stock-based compensation. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ from those estimates.
There have been no material changes to our critical accounting policies during the threenine months ended March 31,September 30, 2021. Please refer to Part II, Item 7 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our 2020 Annual Report on Form 10-K for a discussion of our critical accounting policies and significant judgments and estimates.

Revenue
Royalty revenue for both yearsperiods is related to royalties from Secura Bio and Verastem on net sales of duvelisib. A portion of royalties received is owed to Mundipharma International Corporation Limited, or Mundipharma, and Purdue Pharmaceutical Products L.P., or Purdue. We refer to such portion as the Trailing Mundipharma Royalties (see Note 11 of the notes to our unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q). We and HealthCare Royalty Partners III, L.P., or HCR, entered into a purchase and sale agreement in March 2019, or the HCR Agreement, pursuant to which HCR acquired our interest in royalties received from Verastem on net sales of duvelisib, less the Trailing Mundipharma Royalties (see Note 9 of the notes to our unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q).
Research and Development Expense
Research and development expense increased for the three months ended March 31,September 30, 2021 as compared to the three months ended March 31,September 30, 2020 due to an increase in compensation and recruiting expenses of $0.7 million due primarily to new hires during the period and an increase in clinical development expenses for eganelisib of $0.1 million. Research and development expense increased for the nine months ended September 30, 2021 as compared to the nine months ended September 30, 2020 due to an increase in clinical and development expenses for eganelisib of $0.5$2.2 million, and an increase in consulting expense of $0.4$0.6 million to support continued development of eganelisib.eganelisib and an increase in compensation expense of $0.6 million due primarily to new hires during the period.
We track and accumulate expenses by major program. These expenses primarily relate to payroll and related expenses for personnel working on our programs, process development and manufacturing, preclinical toxicology studies, clinical trial costs and allocated costs of facilities. During the three months ended March 31,September 30, 2021 and 2020, we estimateestimated that we incurred $8.2$7.1 million and $7.3$6.1 million, respectively, on eganelisib. During the nine months ended September 30, 2021 and 2020, we estimated that we incurred $23.2 million and $19.6 million, respectively, on eganelisib.
We do not believe that the historical costs associated with our drug development programs are indicative of the future costs associated with these programs. Due to the variability in the length of time and scope of activities necessary to develop a product candidate and uncertainties related to our cost estimates and our ability to obtain marketing approval for our product candidates, accurate and meaningful estimates of the total costs required to bring our product candidates to market are not available.
Because of the risks inherent in drug development, we cannot reasonably estimate or know:
the nature, timing and estimated costs of the efforts necessary to complete the development of our programs;
the completion dates of these programs; or
the period in which material net cash inflows are expected to commence, if at all, from the programs described above and any potential future product candidates.
There is significant uncertainty regarding our ability to successfully develop any product candidates. These risks include the uncertainty of:
the scope, rate of progress and cost of our clinical trials that we are currently conducting or may commence in the future;

clinical trial results;
the cost of establishing clinical supplies of any product candidates;
the cost and availability of combination and comparator drugs;drugs, such as the current global shortage of the MARIO-3 combination drug nab-paclitaxel, which could affect the MARIO-3 study if the shortage persists;
the cost of filing, prosecuting, defending and enforcing any patent claims and other intellectual property rights relating to our programs under development;
the terms and timing of any collaborations, licensing and other arrangements that we have or may establish in the future relating to our programs under development;
the cost and timing of regulatory approvals,approvals;
the effect of competing technological and market developments; and
the impact of the COVID-19 pandemic.
General and Administrative Expense
General and administrative expense increased for the three months ended March 31,September 30, 2021 as compared to the three months ended March 31,September 30, 2020 due to an increase of $0.4 million in consulting, $0.3 million in professional services and $0.2 million in compensation primarily relatedstock compensation. General and administrative expense increased for the nine months ended September 30, 2021 as compared to the nine months ended September 30, 2020 due to an increase of $0.8 million in consulting, $0.6 million in stock compensation.

Investment and Other Income (Expense)
Investment and other income decreasedincreased for the three months ended March 31,September 30, 2021 as compared to the three months ended March 31,September 30, 2020 primarily as a result of a decrease in the fair value of the warrant liability. Investment and other income decreased for the nine months ended September 30, 2021 as compared to the nine months ended September 30, 2020 primarily as a result of lower yields on our cash and investments.
Non-cash Interest Expense
Non-cash interest expense for the three and nine months ended March 31,September 30, 2021 was the result of the sale of future royalties in relation to the HCR Agreement and BVF Funding Agreement, which we recognized as liabilities that are being amortized using the effective interest method over the life of the arrangements (see Note 9 of the notes to our unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q). Non-cash interest expense for the three and nine months ended March 31,September 30, 2020 was the result of the sale of future royalties in relation to the HCR Agreement. Over the course of the arrangements, the non-cash interest expense will be affected by the amount and timing of estimated royalty revenue, if any. We reassess the effective interest rate on a quarterly basis and adjust the rate prospectively as needed.
Non-cash Related Party Interest Expense
Non-cash related party interest expense for the three and nine months ended March 31,September 30, 2020 was the result of the sale of future royalties in relation to the BVF Funding Agreement. Effective February 17, 2021, Biotechnology Value Fund, L.P. is no longer considered our related party. As a result, we have reclassed interest expense for the three and nine months ended March 31,September 30, 2021 as non-cash interest expense.
Liquidity and Capital Resources
We have not generated any revenue from product sales to date, and we do not expect to generate any such revenue for the foreseeable future, if at all. We have instead relied on the proceeds from sales of equity securities, sales of future royalties, issuances of debt, interest on investments, up-frontupfront license fees, expense reimbursement,reimbursements, milestones, royalties and cost sharing under our collaborations to fund our operations. Because eganelisib is in clinical development, and the outcome of this effort is uncertain, we cannot estimate the actual amounts necessary to successfully complete the development and commercialization of our product candidate or whether, or when, we may achieve profitability.

Cash Flows
For the threenine months ended March 31,September 30, 2021 compared to the threenine months ended March 31,September 30, 2020, our cash used in operating activities increased primarily due to increased operating expenses as we continue clinical development of eganelisib. Our cash used in operating activities in future periods may vary significantly.

Net cash used inprovided by investing activities forincreased during the threenine months ended March 31,September 30, 2021 primarily includeddue to net proceeds of $5.5 million from maturities of available-for-sale securities. Net cash used in investing activities for the three months ended March 31, 2020 primarily includedsecurities of $5.5 million as compared to net purchases of available-for-sale securities of $19.7$2.5 million and proceeds of $20.2 million from maturities of available-for-sale securities.for the nine months ended September 30, 2020.
Net cash provided by financing activities for the threenine months ended March 31,September 30, 2021 was due to $85.8 million in net proceeds from our public offering in February 2021. Net cash provided by financing activities for the threenine months ended March 31,September 30, 2020 included $19.6 million in net proceeds from the sale of future royalties due to us from BVF (see Note 9 of the notes to our unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q). and $6.5 million in net proceeds from our at-the-market facility.
Operating Capital Requirements
As of March 31,September 30, 2021, we had cash and cash equivalents and available-for-sale securities of $106.8$90.1 million. We believe that our existing cash and cash equivalents and available-for-sale securities at March 31,September 30, 2021 will be adequate to satisfy our capital needs for at least the next twelve months from the issuance date of thesethe financial statements included in this Quarterly Report on Form 10-Q based on our current operational plans. We expect to continue to spend significant resources to fund the development and potential commercialization of eganelisib and to incur significant operating losses for the foreseeable future.
Our estimate as to how long we expect our existing cash and cash equivalents and available-for-sale securities to be able to continue to fund our operations is based on assumptions that may prove to be wrong, and we could use our available capital resources sooner than we currently expect. Further, changing circumstances, some of which may be beyond our control, could cause us to consume capital significantly faster than we currently anticipate. Our future funding requirements, both short-term and long-term, will depend on many factors, including, but not limited to:
the scope, progress, results and costs of developing eganelisib, currently in clinical development;
the impact of delays in patient enrollment and site activation related to the COVID-19 pandemicpandemic;
the timing of, and the costs involved in, obtaining regulatory approvals for eganelisib;
subject to receipt of marketing approval, revenue, if any, received from commercial sales of eganelisib;
the timing and amount of additional revenues, if any, received from strategic agreements and funding arrangements;
the timing and amount of additional royalty and milestone payments owed to Takeda;
the costs involved in preparing, filing, prosecuting, maintaining, defending and enforcing patent claims, including litigation costs and the outcome of such litigation;
any breach, acceleration event or event of default under any agreements with third parties;
the outcome of any lawsuits that could be brought against us;

We may seek additional funds through arrangements with collaborators or other third parties, or through project financing. These arrangements would generally require us to relinquish or encumber rights to some of our technologies or product candidates, and we may not be able to enter into such agreements on acceptable terms, if at all. We may also seek additional funding through public or private financings of equity or debt securities, but such financings may not be available on acceptable terms, if at all. In addition, the terms of our financings may be dilutive to, or otherwise adversely affect, holders of our common stock, and such terms may impact our ability to make capital expenditures or incur additional debt. If we are unable to obtain additional funding on a timely basis, we may be required to curtail or terminate some or all of our development programs or to scale back, suspend or terminate our business operations.

Item 4.Controls and Procedures
Our management, with the participation of our principal executive and financial officers, evaluated the effectiveness of our disclosure controls and procedures as of March 31,September 30, 2021. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended, or the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of March 31,September 30, 2021, our principal executive and financial officers concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.
There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the fiscal quarter ended March 31,September 30, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

We are dependent on the success of eganelisib, our only product candidate, which remains subject to clinical testing and regulatory approval. If we are unable to initiate or complete clinical development of, obtain marketing approval for or successfully commercialize eganelisib, either alone or with a collaborator, or if we experience significant delays in doing so, our business could be substantially harmed.
We currently have no products approved for sale and are investing substantially all of our efforts and financial resources in the development of eganelisib. The success of eganelisib will depend on our ability to generate product revenue, which will heavily depend on the successful clinical development and eventual commercialization of eganelisib. We also expect that the success of eganelisib will depend primarily on its therapeutic potential in combination with other therapeutics, such as checkpoint inhibitor therapies, and not as a monotherapy.
To date, we have not obtained approval from the FDA or any comparable foreign regulatory authority to market or sell eganelisib or any other product candidates. Rigorous preclinical testing, testing in clinical trials, and an extensive regulatory approval process are required in the United States and in many foreign jurisdictions prior to the commercial sale of medicinal products. If our current clinical trials for eganelisib are successful, we will need to conduct further clinical trials and will need to apply for regulatory approval before we may market or sell any products based on eganelisib. Satisfaction of these and other regulatory requirements is costly, time consuming, uncertain and subject to unanticipated delays. It is possible that eganelisib will not obtain marketing approval. Even if eganelisib has a beneficial effect, that effect may not be detected during clinical evaluation as a result of one or more of a variety of factors, including the size, duration, design, measurements, conduct or analysis of our clinical trials. Conversely, as a result of the same factors, our clinical trials may indicate an apparent positive effect of eganelisib that is greater than the actual positive effect, if any. Similarly, in our clinical trials we may fail to detect toxicity of or intolerability caused by eganelisib or mistakenly believe that eganelisib is toxic or not well tolerated when that is not in fact the case.
We cannot predict whether we will encounter problems with any of our ongoing or planned clinical trials that will cause us or regulatory authorities to delay, suspend, or discontinue clinical trials or to delay the analysis of data from ongoing clinical trials. Moreover, we, or any collaborators, may experience any of a number of possible unforeseen adverse events in connection with clinical trials, many of which are beyond our control, including:

Table of Contents
inadequate supply, delays in distribution or deficient quality of, or inability to purchase or manufacture drug product, combination drugs, comparator drugs or other materials necessary to conduct our or any collaborators’ clinical trials. For example, BMS is currently experiencing a global manufacturing-related supply shortage of nab-paclitaxel, or Abraxane®, a drug used in the MARIO-3 combination study of patients with unresectable locally advanced or metastatic front-line TNBC. BMS has stated that current inventory and distribution are being allocated by BMS to minimize potential impact to patient supply, and BMS has also indicated that at this time it anticipates limited supply and temporary allocations. We expect our current supply of nab-paclitaxel, orders for which are placed on a rolling basis, to last into the first quarter of 2022, and BMS intends to provide an update regarding the duration of supply constraints in mid-November 2021;
unfavorable results of discussions with the FDA or comparable foreign authorities regarding the scope or design of our, or any collaborators’, clinical trials or our or their interpretation of data from preclinical studies and clinical trials;
delays in receiving, or the inability to obtain, required approvals from institutional review boards or other reviewing entities at clinical sites selected for participation in our clinical trials;
delays in enrolling patients into clinical trials;
a lower than anticipated retention rate of patients in clinical trials due to, among other reasons, patients that enroll in a clinical trial misrepresenting their eligibility to do so or otherwise not complying with the clinical trial protocol, resulting in the need to drop the patients from the clinical trial, increase the needed enrollment size for the clinical trial or extend the clinical trial’s duration and cost;
the number of patients required for clinical trials of eganelisib, the speed of patient enrollment and the rate of participant drop outs may differ from the expectations of us or our collaborators;
the cost of planned clinical trials of eganelisib may be greater than we anticipate;
comparator or combination drugs, or components or ingredients thereof or conducting clinical trials on our behalf or on behalf of any collaborators, to comply with regulatory requirements or meet their contractual obligations to us or any collaborators in a timely manner or at all;
the requirement by regulators or institutional review boards that we, or any collaborators, or our or their investigators, suspend or terminate clinical research for various reasons, including noncompliance with regulatory requirements or their standards of conduct, a finding that the participants are being exposed to unacceptable health risks, undesirable side effects or other unexpected characteristics of eganelisib, or findings of undesirable effects caused by a chemically or mechanistically similar product or product candidate;
the need to repeat or discontinue clinical trials as a result of inconclusive or negative results or unforeseen complications in testing, or because the results of later trials may not confirm positive results from earlier preclinical studies or clinical trials;
unfavorable FDA or other foreign regulatory inspection and review of a clinical trial site, us, or a vendor of ours, or records of any clinical or preclinical investigation;
delays or failures by us or any collaborators in reaching agreement on acceptable clinical trial contracts or clinical trial protocols with prospective trial sites;
failures by the FDA or comparable foreign regulatory authorities to approve the manufacturing processes or facilities of third-party manufacturers with which we, or any collaborators, enter into agreements for clinical and commercial supplies, or subsequent findings of fault with such processes or facilities;
insufficient or inadequate supply or quality of raw materials, manufactured product candidates, combination or comparator drugs, such as the current global shortage of our MARIO-3 comparator, nab-paclitaxel, or other materials necessary to conduct clinical trials of eganelisib, or the inability to acquire such materials at acceptable cost, which may result in interruptions in supply;
significant changes in the approval policies or regulations of the FDA or comparable foreign regulatory authorities, which may rendering our clinical data insufficient to obtain marketing approval;
serious and unexpected drug-related side effects experienced by participants in our or any collaborators’ clinical trials, which may occur even if they were not observed in earlier trials or only observed in a limited number of participants;
a finding that the trial participants are being exposed to unacceptable health risks, undesirable side effects or other unexpected characteristics of eganelisib;
the placement by the FDA or a foreign regulatory authority of a clinical hold on a trial;
outcomes of third party trials of drugs and drug candidates that we also use in our combination trials, such as Roche’s decision to voluntarily withdraw its accelerated approval in the United States for atezolizumab in combination with nab-paclitaxel for patients with PD-L1-positive metastatic TNBC after IMpassion131, Roche’s post marketing study evaluating atezolizumab and paclitaxel in TNBC patients, did not meet its primary endpoint; and

any restrictions on, or post-approval commitments with regard to, any regulatory approval we ultimately obtain that render the product candidate not commercially viable.
The delay, suspension or discontinuation of any of our or any collaborators’ clinical trials, or a delay in the analysis of clinical data for eganelisib, for any of the foregoing reasons, could adversely affect our ability to obtain regulatory approval for and to commercialize eganelisib, increase our operating expenses and have a material adverse effect on our financial results. In particular, if the shortage of nab-paclitaxel described above persists:
we may not have enough supply of nab-paclitaxel to further enroll or maintain patients in MARIO-3;
we may incur increased supply and distribution costs related to the procurement of alternative supply sources; and
if we receive adequate but delayed supply, we could experience delays in the treatment of patients in MARIO-3 or increased operating expenses related to the cost of expedited shipping, labeling, and distribution services.
Product development costs for us, or any collaborators, will increase if we, or they, experience delays in testing or pursuing marketing approvals and we, or they, may be required to obtain additional funds to complete clinical trials and prepare for possible commercialization of eganelisib. We do not know whether our clinical trials will begin as planned, will need to be restructured, or will be completed on schedule or at all. Significant preclinical study or clinical trial delays also could shorten any periods during which we, or any collaborators, may have the exclusive right to commercialize eganelisib or allow our competitors, or the competitors of any current or future collaborators, to bring products to market before we, or any collaborators, do and impair our ability, or the ability of any collaborators, to successfully commercialize eganelisib and may harm our business and results of operations. In addition, many of the factors that lead to clinical trial delays may ultimately lead to the denial of marketing approval of eganelisib, or, in the event that our clinical trials remain unable to demonstrate meaningful clinical benefit, our failure to reach the marketing approval stage at all.
