The Company believes that the product candidates in its pipeline have the potential to be efficacious in a variety of ~~cancers.~~cancers with unmet medical need. The Company currently has the following ~~two~~2 clinical-stage programs: 1. ON 123300 in solid tumors; and 2. oral rigosertib alone or in combination with PD-1 inhibitors for treatment of KRAS-mutated solid tumors. During 2012, Onconova Europe GmbH was established as a wholly owned subsidiary of the Company for the purpose of further developing business in Europe.

The Company has entered into several license and collaboration agreements. In 2011, the Company entered into a license agreement, as subsequently amended, with SymBio Pharmaceuticals Limited ~~("SymBio"~~(“SymBio”), which grants SymBio certain rights to commercialize rigosertib in Japan and Korea.

Under the terms of the agreement, the Company received an upfront payment, and will receive regulatory and commercial milestone payments, as well as royalties on Chinese sales. The key feature of the collaboration is that HanX provides all funding required for Chinese IND enabling studies performed for Chinese Food and Drug Administration IND ~~approval.~~approval, which was received in January 2020.

HanX did not fulfill its obligations under the HanX License Agreement and in January 2020, in accordance with the terms of the HanX License Agreement, the HanX License Agreement was deemed to be void ab initio. Upon this termination, the rights to HanX Product in the HanX Territory reverted to the Company in accordance with the terms of the HanX License Agreement. In addition, the Securities Purchase Agreements terminated automatically effective upon the termination of the HanX License Agreement in accordance with the Securities Purchase Agreements.

The Company has and may continue to delay, scale-back, or eliminate certain of its research and development activities and other aspects of its operations until such time as the Company is successful in securing additional funding. The Company is exploring various dilutive and non-dilutive sources of funding, including equity financings, strategic alliances, business development and other sources. The future success of the Company is dependent upon its ability to obtain additional funding.

Recent Accounting Pronouncements

In August 2018, the FASB issued guidance which changes the disclosure requirements for fair value measurement. The guidance amends the disclosure requirements in ASC Topic 820 by adding, changing, or removing certain disclosures. The guidance is effective for fiscal years beginning after December 15, 2019. The Company adopted this guidance effective January 1, 2020. There was no impact to the Company’s financial position, results of operations or financial statement disclosures as a result of the adoption.
~~In November 2018, the FASB issued guidance, which clarifies the interaction between ASC Topic 808,~~ ~~Collaborative Arrangements~~ ~~, and ASC Topic 606,~~ ~~Revenue from Contracts with Customers~~ . The guidance, among other items, clarifies that certain transactions between collaborative participants should be accounted for as revenue under Topic 606 when the collaborative arrangement participant is a customer in the context of a unit of account. The guidance is effective for fiscal years beginning after December 15, 2019. The Company adopted this guidance effective January 1, 2020. There was no impact to the Company’s financial position and results of operations as a result of the adoption.
In June 2016, the FASB issued new guidance on the accounting for credit losses on financial instruments. The guidance was amended in November 2019. The new guidance introduces an expected loss model for estimating credit losses, replacing the incurred loss model. The new guidance also changes the impairment model for available-for-sale debt securities, requiring the use of an allowance to record estimated credit losses (and subsequent recoveries). The guidance is effective for the Company in fiscal years beginning after December 15, 2022, and interim periods within those years,~~for companies deemed to be smaller reporting companies as of November 15, 2019,~~ with early adoption permitted. The Company is evaluating the impact of the adoption of the standard on its consolidated financial statements.

The tradable warrants which expired in July 2021 were issued in connection with a financing transaction completed in August 2016. Subsequent to the closing of that financing transaction, the Company executed a one-for-fifteen reverse stock split in September 2018. Subsequently, the Company executed a one-for-fifteen reverse stock split in May 2021. As a result, each of the 3,192,140 warrants is exercisable for 1/225 of one share of common stock at an exercise price of $4.92 per warrant. The table above shows the number of shares of common stock which could be

7. Fair Value Measurements

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

The Company utilizes a valuation hierarchy for disclosure of the inputs to the valuations used to measure fair value. This hierarchy prioritizes the inputs into three broad levels as follows. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the financial instrument. Level 3 inputs are unobservable inputs based on the Company’s own assumptions used to measure assets and liabilities at fair value. A financial asset or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.

On January 5, 2016, the Company entered into a securities purchase agreement (the “Securities Purchase Agreement”) with an institutional investor providing for the issuance and sale by the Company of ~~12,912~~861 shares of Common Stock, at a purchase price of ~~$142.50~~$2,137.50 per share and warrants to purchase up to ~~6,456~~430 shares of Common Stock ~~(the~~
13

(the “Warrants”) for aggregate gross proceeds of $1,840,000. The Company has classified the warrants as a liability (see Note 5). The estimated fair value using the Black-Scholes pricing model was approximately $0 at ~~September~~June 30, ~~2020~~2021 and December 31, ~~2019.~~2020. These warrants expired in July 2021.

On July 29, 2016 the Company closed on a Rights Offering, issuing ~~239,986~~16,000 shares of Common Stock, ~~212,801~~14,187 Tradable Warrants and ~~43,760~~2,918 Pre-Funded Warrants. The Tradable Warrants are exercisable for a period of five years for one share of Common Stock at an exercise price of ~~$73.80~~$1,107 per share. After the one-year anniversary of issuance, the Company may redeem the Tradable Warrants for ~~$0.001~~$0.015 per Tradable Warrant if the volume weighted average price of its Common Stock is above ~~$184.50~~$2,767.50 for each of 10 consecutive trading days. The Company has classified the Tradable Warrants as a liability (see Note 5). The Tradable Warrants have been listed on the Nasdaq Capital Market since issuance and the Company regularly monitors the trading activity. The Company has determined that an active and orderly market for the Tradable Warrants has developed and that the Nasdaq Capital Market price is the best indicator of fair value of the warrant liability. The quoted market price was used to determine the fair value at December 31, ~~2019~~2020 and ~~September~~June 30, ~~2020.~~
~~The Company estimated the fair value of the non-tradable warrant liability at September 30, 2020, using the Black-Scholes option pricing model with the following weighted-average assumptions:~~
~~Risk-free interest rate~~ ~~0.12~~ %
~~Expected volatility~~ ~~121.82~~ %
~~Expected term~~ ~~0.77 years~~
~~Expected dividend yield~~ 0 %
~~Expected volatility is based on the historical volatility of the Company’s Common Stock since its IPO~~2021. These warrants expired in July ~~2013.~~2021.

8. Stock-Based Compensation
The 2007 Equity Compensation Plan as amended (the “2007 Plan”), amended, restated and renamed the Company’s 1999 Stock Based Compensation Plan (the “1999 Plan”), which provided for the granting of incentive and nonqualified stock options and restricted stock to its employees, directors and consultants at the discretion of the board of directors.
The 2013 Equity Compensation Plan (the “2013 Plan”), amended, restated and renamed the 2007 Plan. Under the 2013 Plan, the Company may grant incentive stock options, non-statutory stock options, stock appreciation rights, restricted stock, restricted stock units, deferred share awards, performance awards and other equity-based awards to employees, directors and consultants. The Company initially reserved 40,718 shares of Common Stock for issuance, subject to adjustment as set forth in the 2013 Plan. The 2013 Plan included an evergreen provision, pursuant to which the maximum aggregate number of shares that may be issued under the 2013 Plan is increased on the first day of each fiscal year by the lesser of (a) a number of shares equal to four percent (4%) of the issued and outstanding Common Stock of the Company, without duplication, (b) 13,333 shares and (c) such lesser number as determined by the Company’s board of directors, subject to specified limitations.

The 2018 Omnibus Incentive Compensation Plan (the “2018 Plan”) was unanimously approved by the Company’s Board of Directors on May 24, 2018 and was approved by the Company’s stockholders on June 27, 2018. The 2018 Plan replaces the 2013 Plan. Upon stockholders’ approval of the 2018 Plan, no further awards will be made under the 2013 Plan. Awards granted under the 2013 Plan will continue in effect in accordance with the terms of the applicable award agreement and the terms of the 2013 Plan in effect when the awards were granted.

Under the 2018 Plan, the Company may grant incentive stock options, non-qualified stock options, stock awards, stock units, stock appreciation rights and other stock-based awards to employees, non-employee directors and consultants, and advisors. The maximum aggregate number of shares of the Company’s common stock that may be issued under the 2018 Plan is 402,354, which is equal to the sum of (i) 400,000 shares of the Company’s common stock, plus (ii) 2,354 shares, which is the number of shares of the Company common stock reserved for issuance under the 2013 Plan that remained available as of the effective date of the 2018 Plan. In addition, the number of shares of common stock subject to outstanding awards under the 2013 Plan that terminate, expire, or are cancelled, forfeited, exchanged, or surrendered without having been exercised, vested, or paid in shares under the 2013 Plan after the effective date of the 2018 Plan will be available for issuance under the 2018 Plan.26,823.

The 2018 Plan was amended and restated following unanimous approval of the Company’s Board of Directors on April 24, 2019 and was approved by the Company’s shareholders on June 17, 2019. The amended 2018 Plan (the “Amended Plan”) allowed for an additional ~~589,500~~39,300 shares of the Company’s common stock that may be issued under the Amended Plan with respect to awards made on and after June 17, 2019. At ~~September~~June 30, ~~2020,~~2021, there were ~~50,194~~5,205 shares available for future issuance.

Stock-based compensation expense includes stock options granted to employees and non-employees and has been reported in the Company’s statements of operations and comprehensive loss in either research and development expenses or general and administrative expenses depending on the function performed by the optionee. NoNaN net tax benefits related to the stock-based compensation costs have been recognized since the Company’s inception. The

The Company uses the Black-Scholes option-pricing model to estimate the fair value of stock options at the grant date. The Black-Scholes model requires the Company to make certain estimates and assumptions, including estimating the fair value of the Company’s Common Stock, assumptions related to the expected price volatility of the Common Stock, the period during which the options will be outstanding, the rate of return on risk-free investments and the expected dividend yield for the Company’s stock.

As of ~~September~~June 30, ~~2020,~~2021, there was ~~$433,000~~$102,000 of unrecognized compensation expense related to the unvested stock options ~~issued from April 24, 2013 through September 30, 2020,~~ which is expected to be recognized over a weighted-average period of approximately ~~1.92~~2.29 years.

The weighted-average valuation assumptions were determined as follows:

·● Risk-free interest rate: The Company based the risk-free interest rate on the interest rate payable on U.S. Treasury securities in effect at the time of grant for a period that is commensurate with the assumed expected option term.

·● Expected term of options: Due to its lack of sufficient historical data, the Company estimates the expected life of its employee stock options using the “simplified” method, as prescribed in Staff Accounting Bulletin (SAB) No. 107, whereby the expected life equals the arithmetic average of the vesting term and the original contractual term of the option.

·● Expected stock price volatility: Expected volatility is based on the historical volatility of the Company’s Common Stock since its IPO in July 2013.

·● Expected annual dividend yield: The Company has never paid, and does not expect to pay, dividends in the foreseeable future. Accordingly, the Company assumed an expected dividend yield of 0.0%.

·● Estimated forfeiture rate: The Company’s estimated annual forfeiture rate on stock option grants was 4.14% in ~~2020~~2021 and ~~2019,~~2020, based on the historical forfeiture experience.

~~Grants~~Grants of PSUs and SARs

On July 9, 2020, the compensation committee of the board of directors and the board approved a cash bonus program of cash-settled stock appreciation right (“2020 SAR”) awards and cash-settled performance stock unit (“2020 PSU”) awards to the Company’s employees. An aggregate of 2020 SAR awards with respect to ~~3,850,700~~256,713 shares of common stock and 2020 PSU awards with respect to ~~1,863,300~~124,220 shares of common stock were granted to the Company’s employees. The 2020 SAR awards will be settled in cash, vest 33% on the first anniversary of the date of grant, and the remaining 67% monthly over the next 24 months, have a per-share base amount of ~~$0.56,~~$8.40, which was the closing sales price of a share of the Company’s common stock on the grant date, and are in all cases subject to the terms and conditions of the Company’s form of SAR award agreement.

The 2020 PSU awards vest 50% upon the submission of a new drug application (“NDA”) to the U.S. FDA for rigosertib in higher-risk myelodysplastic syndromes (“HR-MDS”) and 50% upon U.S. FDA approval of rigosertib for HR-MDS. The 2020 PSU awards have a maximum value of ~~$1.44~~$21.60 per share. The maximum price per share is the per-share value based on the Company’s market capitalization at ~~$250~~$250 million and the Company’s outstanding shares of common stock, which was ~~174,177,448~~11,611,829 shares on July 9, 2020. In all cases, the 2020 PSU awards are subject to the terms and conditions of the Company’s form of PSU award agreement.

In addition, on July 9, 2020, based on the recommendation of the compensation committee, the board approved a change in the non-employee director compensation policy that would provide for an annual SAR award (“2020 Director SAR”) with respect to ~~125,000~~8,333 shares of common stock for each of the Company’s non-employee directors. No other changes to the non-employee director compensation policy were approved and, on July 9, 2020, the Board approved the initial ~~125,000~~8,333 2020 Director SAR award to each of the non-employee directors ~~totaling 875,000 SARs.~~for an aggregate total of 58,333 2020 Directors SAR awards granted. The 2020 Director SAR awards vest on the first anniversary of grant subject to the director’s continued service and will be settled in cash, have a per-share base amount of ~~$0.56,~~$8.40, and are in all cases subject to the terms and conditions of the Company’s form of 2020 Director SAR award agreement.

Each SAR subject to ana 2020 SAR award represents the right to a cash payment equal to the excess, if any, of (i) the fair market value of each underlying share of the Company’s common stock, determined on the date of exercise of the SAR minus (ii) the base amount. Pursuant to the terms of the SAR awards, in no event may the cash payment for each SAR exceed ~~$0.88,~~$13.20, which is the maximum price per share of ~~$1.44,~~$21.60, minus the base amount of ~~$0.56,~~$8.40, subject to adjustment in accordance with the terms of the Stock Appreciation Right Award Agreement.

On February 17, 2021, the compensation committee of the board of directors and the board approved a cash bonus program of cash-settled stock appreciation right (“2021 SAR”) awards and cash-settled performance stock unit (“2021 PSU”) awards to the Company’s employees. An aggregate of 2021 SAR awards with respect to 100,000 shares of common stock and 2021 PSU awards with respect to 100,000 shares of common stock were granted to the Company’s employees. The 2021 SAR awards will be settled in cash, vest 33% on the first anniversary of the date of grant, and the remaining 67% monthly over the next 24 months, have a per-share base amount of $22.65, which was the closing sales price of a share of the Company’s common stock on the grant date, and are in all cases subject to the terms and conditions of the Company’s form of SAR award agreement. Each SAR subject to a 2021 SAR award represents the right to a cash payment equal to the excess, if any, of (i) the fair market value of each underlying share of the Company’s common stock, determined on the date of exercise of the 2021 SAR minus (ii) the base amount. Pursuant to the terms of the 2021 SAR awards, in no event may the cash payment for each SAR exceed $15.45, which is the maximum price per share of $38.10, minus the base amount of $22.65, subject to adjustment in accordance with the terms of the Stock Appreciation Right Award Agreement. The maximum price per share is the per-share value based on the Company’s market capitalization at $600 million and the Company’s outstanding shares of common stock, which was 15,767,492 shares on February 17, 2021.

The ~~SAR~~2021 PSU awards vest 20% upon the initiation of a new clinical program with an in-licensed compound, 20% for reaching the recommended Phase 2 dose for any compound, 20% for the first patient enrolled in the expansion cohort of the Phase 1 ON123300 clinical trial, 20% for the first patient enrolled in a registrational study for any compound, and 20% for the topline data of a registrational study for any compound. The 2021 PSU awards have a maximum value of $38.10 per share. The maximum price per share is the per-share value based on the Company’s approximate market capitalization at $600 million and the Company’s outstanding shares of common stock, which was 15,767,492 shares on February 17, 2021.

9. Research Agreements

The Company has entered into various licensing and right-to-sublicense agreements with educational institutions for the exclusive use of patents and patent applications, as well as any patents that may develop from research being conducted by such educational institutions in the field of anticancer therapy, genes and proteins. Results from this research have been licensed to the Company pursuant to these agreements. Under one of these agreements with Temple University (“Temple”), the Company is required to make annual maintenance payments to Temple and royalty payments based upon a percentage of sales generated from any products covered by the licensed patents, with minimum specified royalty payments. As no0 sales had been generated through ~~September~~June 30, ~~2020~~2021 under the licensed patents, the Company has not incurred any royalty expenses related to this agreement. In addition, the Company is required to pay Temple a percentage of any sublicensing fees received by the Company.

10. ~~License and Collaboration Agreement~~
~~HanX Rigosertib Agreement (terminated)~~
On May 10, 2019, the Company entered into a License and Collaboration Agreement (the "HanX License Agreement") with HanX and two Securities Purchase Agreements (the "HanX Securities Purchase Agreements"), one with HanX and the other with an affiliate of HanX.
Under the terms of the HanX License Agreement, the Company granted HanX an exclusive, royalty-bearing license, with the right to sublicense, to study and commercialize rigosertib in greater China (the "HanX Territory," including the People's Republic of China, Hong Kong, Macau and Taiwan).
In exchange for these rights, the agreement required HanX to make upfront payments to the Company totaling $4 million, including a $2.0 million upfront fee and an investment totaling $2.0 million to purchase shares of the Company at a premium to market. HanX was also required to dedicate $2.0 million in local currency, to be placed in escrow, for clinical development expenses in the HanX Territory. In addition, the agreement provided for potential payments to the Company for regulatory, development and sales-based milestone payments up to $45.5 million and tiered royalties up to double digits on net sales in in the HanX Territory. The Company would supply rigosertib for sale in the HanX Territory.
The HanX License Agreement also contained certain provisions for termination by either party in the event of breach of the HanX License Agreement by the other party, subject to a cure period, or bankruptcy of the other party.
Under the terms of the HanX Securities Purchase Agreement, HanX and its affiliate agreed to make upfront equity investments in the Company at a specified premium to the Company's share price. The common stock purchased by HanX and its affiliates is subject to certain lock-up restrictions and HanX and its affiliates are entitled to certain registration and participation rights.
The Company assessed the HanX License Agreement for revenue recognition in accordance with ASC 606 and determined that there are two distinct performance obligations: the license and the supply of rigosertib for sale in the HanX Territory. The Company concluded that control of the license had been transferred to HanX during the three months ended June 30, 2019 and recognized license revenue of $1.7 million, which is net of applicable taxes withheld by the Chinese government, related to the $2.0 million upfront fee. The Company believes a portion of the tax being withheld by the Chinese government may be recoverable at a later date and could be recognized as license revenue if and when recovered by the Company. The $1.7 million was recorded as a receivable at June 30, 2019 and the payment was received in August 2019.
Pursuant to the HanX Securities Purchase Agreements, closing of one of the upfront equity investments occurred on May 15, 2019 when an affiliate of HanX purchased 103,520 shares of common stock for $0.5 million. The total amount of the premium was $0.1 million and this amount was recognized as license revenue during the three months ended June 30, 2019. The remaining upfront equity investments represent equity-classified forward contracts for the purchase of the Company's equity at a pre-determined price. The premium of the future equity purchase from HanX as of the contract date of $0.2 million was recognized as license revenue during the three months ended June 30, 2019 and was included in other current assets, pending receipt of payment.
On July 9, 2019, the Company extended the deadline for payments under the HanX License Agreement and the HanX Securities Purchase Agreements. On August 8, 2019 the Company received the non-refundable license fee from HanX. On August 14, 2019, the Company further extended the deadline of HanX's remaining upfront payments relating to its equity investment in the Company while HanX continued to seek Chinese regulatory approval for such equity investment. In December 2019, the Company reassessed the likelihood of receiving the $0.2 million premium on the equity investment previously recorded as revenue. The Company reversed the $0.2 million revenue in December 2019.
On January 16, 2020, the Company determined HanX did not fulfill its obligations under the License Agreement and, in accordance with the terms of the License Agreement, the License Agreement was deemed to be void ab initio. Upon this termination, the rights to Product in the Territory reverted to the Company in accordance with the terms of the License Agreement. In addition, the Securities Purchase Agreements terminated automatically effective upon the termination of the License Agreement in accordance with the Securities Purchase Agreements.

Overview

We are a clinical-stage biopharmaceutical company focused on discovering and developing novel ~~small molecule product candidates primarily to treat~~products for patients with cancer. We have proprietary targeted anti-cancer agents designed to ~~inhibit~~disrupt specific cellular pathways that are important tofor cancer cells. In August 2020, our Phase 3 INSPIRE trial concluded after the primary endpoint failed to demonstrate an improvement in survival. We are currently evaluating other compounds in our pipeline and potential compounds for in-licensing opportunities.cell proliferation. We believe that the product candidates in our pipeline have the potential to be efficacious in a variety of cancers with unmet medical need. We have the following two clinical-stage programs: 1. ON 123300, multi-kinase inhibitor in solid tumors; and 2. ~~oral~~ rigosertib alone or in combination with PD-1 inhibitors for treatment of ~~KRAS-mutated~~ solid tumors.
~~Our recent efforts have been primarily focused on our product candidate, rigosertib,~~ We are currently evaluating potential compounds for patients with myelodysplastic syndromes ("MDS"). Rigosertib has been tested in an intravenous formulation as a single agent for patients with relapsed/refractory higher-risk MDS (“HR-MDS”), and an oral formulation as a single agent in lower risk MDS or in combination with azacitidine for patients with newly diagnosed or refractory HR-MDS.
In December 2015, we enrolled the first patient into our INSPIRE trial, a randomized controlled Phase 3 clinical trial of intravenous rigosertib ("rigosertib IV") in a population of patients with HR-MDS after failure of hypomethylating agent ("HMA") therapy. The primary endpoint of INSPIRE was improvement in overall survival. We completed enrollment of the required 360 randomized patients in March 2020, and in July 2020, the required number of survival events was reached.
On August 24, 2020, we announced topline results from the INSPIRE trial, which assessed the efficacy and safety of IV rigosertib in HR-MDS patients. The trial did not meet its primary endpoint of improved survival for patients randomized to IV rigosertib compared to the control arm .
The primary endpoint of the trial was overall survival, comparing IV rigosertib plus best supportive care to physician's choice (“PC”) plus best supportive care in patients who had progressed on, failed to respond to, or relapsed after previous treatment with an HMA within nine cycles over the course of one year after initiation of HMA treatment. A pre-specified analysis in the very high risk (“VHR-MDS”) patient subgroup was also conducted. Results of INSPIRE demonstrated that in the intent-to-treat analysis patients randomized to IV rigosertib resulted in overall survival of 6.4 months, versus 6.3 months for PC (Hazard ratio 1.13, 95% Confidence interval 0.88-1.46; p=0.33) in the HR-MDS population. Overall survival in the pre-specified VHR-MDS subgroup of patients was identical in the two study arms (5.2 months) (Hazard ratio 1.12, 95% Confidence interval 0.83-1.51; p=0.47). Safety analysis indicates that IV rigosertib was generally well tolerated, with reported adverse events similar to those observed in previous clinical studies with IV rigosertib in MDS. Serious adverse events (“SAEs”) were uncommon, with a similar profile of SAEs in both study arms.
Currently, we are conducting genomics profiling of samples from patients enrolled in the INSPIRE trial. These data may provide new insights into the prognosis of HR MDS with mutations of the RAS pathway and importantly into the future treatment of RAS-mutated diseases such as inherited Rasopathies and Ras-mutated cancers.
Based on the results of the INSPIRE trial and the previously conducted ONTIME Phase 3 trial, we currently do not plan to further pursue intravenous rigosertib for treating HR-MDS. We plan to continue to focus on the other programs in our pipeline, including oral rigosertib in KRAS mutated cancers and our novel CDK4/6 + ARK5 multi kinase inhibitor ON 123300. We will direct our efforts to these programs and are also reviewing potential in-licensing opportunities.

Our net losses were ~~$18.7~~$8.9 million and ~~$15.8~~$12.5 million for the ~~nine~~six months ended ~~September~~June 30, ~~2020~~2021 and ~~2019,~~2020, respectively. As of ~~September~~June 30, ~~2020,~~2021, we had an accumulated deficit of ~~$422.1~~$437.4 million. We expect to incur significant expenses and operating losses for the foreseeable future as we continue the development ~~and clinical trials~~ of, and seek regulatory approval for, our product candidates, even if milestones under our license and collaboration agreements may be met. As of ~~September~~June 30, ~~2020,~~2021, we had ~~$24.2~~$43.7 million in cash and cash equivalents.

On January 12, 2021, we closed on an offering of common stock. We issued 1,303,408 shares of common stock. Net proceeds were approximately $8.5 million.

On February 16, 2021, we closed on an offering of common stock. We issued 1,916,667 shares of common stock. Net proceeds were approximately $26.7 million.

On May 20, 2021, we amended our certificate of incorporation to effect a one-for-fifteen reverse stock split of our common stock. All common stock, equity, share and per share amounts in the financial statements and notes have been retroactively adjusted to reflect the reverse stock split.

On May 20, 2021, we amended our certificate of incorporation to decrease the number of authorized shares of common stock from 250,000,000 to 125,000,000.

We believe that our cash and cash equivalents of ~~$24.2~~$43.7 million, at ~~September~~June 30, ~~2020,~~2021, will be sufficient to fund our operations and ongoing trials ~~into~~for more than eighteen months from the ~~first quarter~~date of ~~2022.~~this filing. We do not have a recurring source of revenue to fund our operations and will need to raise additional funds to continue to develop and apply for regulatory approval for our drug candidates.

We are exploring various sources of funding for development and applying for regulatory approval of our research compounds as well as for our ongoing operations. If we raise additional funds through strategic collaborations and alliances or licensing arrangements with third parties, which may include existing collaboration partners, we may have to relinquish valuable rights to our technologies or product candidates or grant licenses on terms that are not favorable to us. There can be no assurance, however, that we will be successful in obtaining such financing in sufficient amounts, on terms acceptable to us, or at all. In addition, there can be no assurance that we will obtain approvals necessary to market our product candidates or achieve profitability or sustainable, positive cash flow. If we are unable to successfully raise sufficient additional capital, through future financings or through strategic and collaborative arrangements, we will not have sufficient cash to fund our ongoing trials and operations.

ON 123300 ~~- Cyclin Dependent Kinases (CDK) 4/~~— Differentiated Multi-Kinase Inhibitor Targeting CDK4/6 ~~and ARK5 Inhibitor~~

We believe based on data from preclinical studies, that ON 123300 has the potential to overcome the limitations of the current generation of approved cyclin dependent kinase (CDK 4/6) inhibitors. Pursuant to a license agreement with Temple University dated January 1, 1999 as amended March 21, 2013, we licensed compounds including ON 123300 from Temple University. ON 123300 monolactate (ON 123300) is a novel multi kinase inhibitor that targets both CDK4/6 as well as other tyrosine kinases believed to drive tumor proliferation. The below table depicts the half-maximal inhibitory concentration (IC₅₀) of ON 123300 and Palbociclib, which is a quantitative measure indicating the concentration of each drug needed to inhibit, in vitro, these listed kinases by 50%.

One such tyrosine kinase ARK5, ~~(NUAK1). ARK5~~also known as NUAK1, regulates AKT dependent cell survival and migration (perhaps involved with metastases) through inhibition of cellular metabolism. The combination of CDK and ARK5 inhibitors in the same molecular entity is proposed to have a differentiated ~~multi-kinase~~ effect on cancer cells by simultaneously inhibiting both cell cycle (cytostatic) and cellular metabolism (cytotoxic) pathways through CDK and ARK5, respectively. We and our partner, HanX Biopharmaceuticals, Inc. (“HanX”), have recently ~~have~~ initiated clinical studies to begin evaluating whether these findings from preclinical studies may translate to clinical activity or clinical ~~benefits~~benefit in cancer patients.
~~The effectiveness of first-generation non-selective CDK inhibitors (Selicilib/roscovitine and Alvocidib/flavopiridol) in early trials was limited due to toxicities (Blachly 2013~~). Second-generation compounds (palbociclib, ribociclib and abemaciclib) specifically inhibit CDK4 and 6, thereby inhibiting retinoblastoma (RB) protein phosphorylation. The second generation CDK4/6 inhibitors have substantially improved clinical outcomes for patients with hormonal-receptor (HR) positive metastatic breast cancer (~~Hortobagyi 2018, Sledge 2017, Finn 2016). Several CDK4/6 inhibitors have recently been approved and are now standard of care in combination with hormonal therapy for patients with HR-positive, HER2-negative metastatic breast cancer.~~
In December 2017, we entered into a license and collaboration agreement with HanX Biopharmaceuticals, a company focused on development of novel oncology products, for the further development, registration and commercialization in China of ON 123300. Under the terms of the agreement, we received an upfront payment, and will receive regulatory and commercial milestone payments, as well as royalties on any future Chinese sales if the drug is approved. The key feature of the 2017 collaboration was that HanX provided all funding required for the Chinese IND thereby enabling the studies necessary in order to seek IND approval by the Chinese Food and Drug Administration (Chinese FDA). In the fourth quarter of 2019, HanX filed an IND with the Chinese FDA which was approved on January 6^, 2020. We and HanX also intended for these studies underlying the Chinese IND approval, to meet the US FDA standards for IND approval. Accordingly, such studies may be used by us for an IND filing with the US FDA. In September 2020, a Phase 1 Study with ON123300 in cancer patients was initiated in China. We maintain global rights to the study and study data outside of China.
Our IND submission to the US FDA is planned by the end of 2020 with enrollment into a first in human (FIH) study anticipated for the first quarter of 2021. The study will assess the safety, tolerability and pharmacokinetics of ON 123300 administered orally at increasing doses starting at 40 mg daily for consecutive 28-day cycles in patients (n=36) with relapsed/refractory advanced cancer, including but not limited to, patients with breast cancer that is resistant to approved second generation CDK 4/6 inhibitors as well as patients diagnosed with advanced Non-Hodgkin’s lymphoma. In partnership with HanX, a complimentary Phase 1 study for patients with advanced relapsed/refractory cancer has been initiated in China at two sites and the first patient was enrolled on September 15, 2020. Collectively, these two Phase 1 studies are expected to provide data regarding the safety profile of ON 123300 and preliminary efficacy signals in patients with advanced cancer.
Positive preclinical data was announced at the American Association for Cancer Research (AACR) annual meeting, which took place April 1-5, 2017 in Washington, DC, for ON 123300, a first-in-class dual inhibitor of CDK4/6 + ARK5. We believe our CDK inhibitor is differentiated from other agents in the market or in development due to its dual inhibition of CDK4/6 and ARK5.
Retinoblastoma (Rb) protein is a master regulator of cell division and is critical to several cellular processes including senescence, self-renewal, replication and apoptosis (Engel, 2015). It is believed that inactivation of Rb by CDKs leads to malignant cell formation and occurs in the pathogenesis of most cancers. In a preclinical Retinoblastoma (Rb) positive xenograft model for breast cancer, ON 123300 activity was shown to be similar to palbociclib (Pfizer's Ibrance ®. Moreover, based on the same preclinical model, ON 123300 may have the potential advantage of reduced neutropenia when compared to palbociclib. Whereas both compounds resulted in decreased RBC and platelet counts in this preclinical model system, palbociclib was found to have a more prominent and statistically significant (P< 0.05) inhibitory effect on neutrophil counts when compared to ON 123300. These results would need to be replicated in the human model.

In certain in vitro models, the kinase inhibitory profile of ON 123300 had the highest activity against CDK4, CDK6, ARK5, FGFR1, PDGFRß and PI3K-δ, all of which are associated with the growth, survival and metastasis of human tumor cells (Reddy, 2014). In an in vitro investigation of ON 123300 against a broad spectrum of human tumor cell lines, ON 123300 displayed potent antiproliferative activity, with 50% growth inhibitory concentrations (GI50) ranging from 0.02 µM to 1.5 µM. In these in vitro models, ON 123300 exhibited a broad range of activity against a wide spectrum of cell lines of both hematological origin (lymphoma, leukemia and myeloma) as well as solid tumors derived from multiple organ sites. Studies on drug-resistant human tumor cell lines suggested that ON 123300 is not a multidrug resistance gene (mdr1) substrate and may be active against drug-resistant tumor cell lines (IBv.1 2020; Reddy, 2014). The activity of ON 123300 does not appear to be affected by the overexpression of MDR-1 and induced apoptosis in both ibrutinib-sensitive and ibrutinib-resistant patient derived cells (Divakar, 2016). The ability of ON 123300 to inhibit the CDK4/6/RB1 pathway has also been shown in pre-clinical testing of mantle cell lymphoma (Divakar, 2016), multiple myeloma (Perumal, 2016) and colorectal cancer (IBv.1 2020).

The effectiveness of first-generation non-selective CDK inhibitors (Selicilib/roscovitine and Alvocidib/ flavopiridol) in early trials was limited due to toxicities (Blachly 2013). Second-generation compounds (palbociclib, ribociclib and abemaciclib) specifically inhibit CDK4 and 6, thereby inhibiting retinoblastoma (RB) protein phosphorylation. The second generation CDK4/6 inhibitors have substantially improved clinical outcomes for patients with hormonal-receptor (HR) positive metastatic breast cancer (Hortobagyi 2018, Sledge 2017, Finn 2016). Several CDK4/6 inhibitors (palbociclib, ribociclib and abemaciclib) have been approved and are now standard of care either alone (abemaciclib) or in combination with anti-estrogen therapy for patients with HR-positive, HER2-negative metastatic breast cancer. Another CDK4/6 inhibitor has recently been approved, trilaciclib, in the supportive care space, for the prevention of myelosuppression following chemotherapy.

In December 2017, we entered into a license and collaboration agreement with HanX, a company focused on development of novel oncology products, for the further development, registration and commercialization in China of ON 123300. Under the terms of the agreement, we received an upfront payment, and will receive regulatory and commercial milestone payments, as well as royalties on any future Chinese sales if the drug is approved.

Application (a “IND”) thereby enabling the studies necessary in order to seek IND approval by the National Medical Products Administration (Chinese FDA). In the fourth quarter of 2019, HanX filed an IND with the Chinese FDA which was approved on January 6, 2020. We and HanX also intended for these studies underlying the Chinese IND approval, to meet the US Food and Drug Administration (“FDA”) standards for IND approval. Accordingly, such studies were used by us for an IND filing with the US FDA. In September 2020, a Phase 1 Study with ON123300 in cancer patients was initiated in China. We maintain global rights to the study and study data outside of China.

Our IND submission to the US FDA was submitted in November 2020 and the FDA Study May Proceed letter was issued in December 2020. Enrollment into the US phase 1 study commenced in May 2021. Enrollment in the first cohort of the Phase 1 solid tumor study of ON 123300 is complete with no dose limiting toxicities (DLT’s) observed. The second cohort is currently open for enrollment. The study will assess the safety, tolerability and pharmacokinetics of ON 123300 administered orally at increasing doses starting at 40 mg daily for consecutive 28-day cycles in patients (n=36) with relapsed/refractory advanced cancer, including but not limited to, patients with breast cancer that is resistant to approved second generation CDK 4/6 inhibitors as well as patients diagnosed with advanced Non-Hodgkin’s lymphoma. In partnership with HanX, a complementary Phase 1 study for patients with advanced relapsed/refractory cancer has been initiated in China at three sites and the first patient was enrolled on September 15, 2020. The first two dose cohorts have been completed and the third dose cohort is ongoing. No dose limiting toxicities have been observed to date. Collectively, these two Phase 1 studies are expected to provide data regarding the safety profile of ON 123300 and potentially preliminary efficacy signals in patients with advanced cancer.

Positive preclinical data was announced at the American Association for Cancer Research (AACR) annual meeting, which took place April 1-5, 2017 in Washington, DC, for ON 123300. We believe our CDK inhibitor is differentiated from other agents in the market or in development due to its multi-kinase inhibition.

Retinoblastoma (Rb) protein is a master regulator of cell division and is critical to several cellular processes including senescence, self-renewal, replication and apoptosis (Engel, 2015). It is believed that inactivation of Rb by CDKs leads to malignant cell formation and occurs in the pathogenesis of most cancers. In a preclinical Retinoblastoma (Rb) positive xenograft model for breast cancer, ON 123300 activity was shown to be similar to palbociclib (Pfizer’s Ibrance ^®). Moreover, based on the same preclinical model, ON 123300 may have the potential advantage of reduced neutropenia when compared to palbociclib. Whereas both compounds resulted in decreased RBC and platelet counts in this preclinical model system, palbociclib was found to have a more prominent and statistically significant (P< 0.05) inhibitory effect on neutrophil counts when compared to ON 123300. These results would need to be replicated in clinical trials.

In vitro studies compared the growth inhibitory activity of ON 123300 and palbociclib in breast cancer cell lines with mutated or deleted RB, which demonstrated resistance to palbociclib but retained sensitivity towards ON 123300 (IBv.1 2020). Further analyses using mantle cell lymphoma cells indicated that ON 123300 was able to induce cell death via induction of apoptosis by inhibiting the AKT/PI3K pathway while palbociclib treatment was only able to induce cell cycle arrest due to the inhibition of CDK4/6 (Divakar, 2016). ON 123300 treatment was associated with the presence of several apoptotic markers (PARP, caspase 3, caspase 7 and caspase 9) and ON 123300 (but not palbociclib) led to the generation of apoptotic cells. Overall, apoptosis following ON 123300 exposure has been observed in the following cell lines: breast cancer (IBv.1 2020, Reddy, 2014), mantle cell lymphoma (Divakar, 2016), multiple myeloma (Perumal, 2016) and colorectal cancer (IBv.1 2020).

In addition to CDK4/6 and PI3 Kinase, ON 123300 may inhibit ARK5 (NUAK1) (IC50 of 4.95 nM) (IBv.1 2020, Reddy, 2014) while palbociclib does not. ARK5 is a member of the ~~AMP-activated~~AMP -activated protein kinase (AMPK) family and is thought to function as a key regulator of cellular energy homeo-stasis (Liu, 2012) and is important in a number of cancer cell survival pathways. Overexpression of ARK5 is associated with poor prognosis in hepatocellular carcinoma (Cui, 2013), ovarian cancers (Phippen, 2016) and glioblastoma (Lu, 2013). ARK5 is involved in the increased invasiveness, migration and metastatic potential of breast cancer cells (Chang, 2012), colorectal cancer (Kusakai, 2004), gastric cancer (Chen, 2017), and multiple myeloma (Suzuki et al., 2005). ON 123300 inhibits ARK5 resulting in down regulation of the mTOR/MYC/RB1 pathways leading to cell cycle arrest and apoptosis.

Table of Contents
Because ARK5 activity is now recognized as crucial in promoting cancer cell migration and invasion (Kusaki, 2004) the effect of ON 123300 treatment may have an impact on cell migration and wound healing. In certain in vitro models, ON 123300 was able to inhibit the percent migration of U87 cells in a ~~concentration-dependent~~concentration- dependent manner. The time and concentrations that were tested did not result in cell death but did inhibit cell division at the higher concentrations (IBv.1 2020). The ability of ON 123300 to inhibit cell migration was compared to palbociclib using a wound healing model. Triple negative cancer cell migration was inhibited for 72 hours in the presence of ON 123300 but not in the presence of palbociclib (IBv.1 2020).

The pathogenesis and progression of breast cancer is linked to C-Myc expression which is subsequently dependent on ARK5 activity. The inhibition of ARK5 has been shown to be lethal in MYC overexpressing tumors (Liu, 2012) and targeting ARK5 in the inhibitory profile of ON 123300 has the potential to overcome the emergence of resistance to CDK4/6 inhibitors due to the loss of retinoblastoma function and C-Myc overexpression. Preclinical studies with tumor cell lines suggest that several malignancies including HR-positive breast cancer, colorectal carcinoma, hepatocellular carcinoma, mantle cell lymphoma and multiple myeloma, may be clinically responsive to ON 123300 exposure (Reddy, 2014, Divakar, 2016, Perumal, 2016). Furthermore, ON 123300 has been tested in five murine xenograft models (breast cancer including triple negative disease, colorectal, mantle cell lymphoma and multiple myeloma) and was found to have on-target activity and be non-toxic to the animals (Reddy, 2014; Divakar, 2016; Perumal, 2016; and IBv.1 2020).

Cancer cells can lose RB function through mutation and become resistant or insensitive to palbociclib. ~~The mechanism of action of these second generation agents is primarily cytostatic and not cytotoxic.~~ Generally, ~~these~~ second generation agents have not been shown to be suitable for single agent therapy and must be used in combination with hormonal ~~therapy due to limitations of the cytostatic mechanism.~~therapy. In addition, the rate of disease progression that occurs, especially in patients with visceral disease (Hortobagyi 2018), may benefit from the novel ~~dual~~ inhibitory effects of ON 123300. This hypothesis needs to be proven in a clinical trial.

Unfortunately, mechanisms of acquired resistance are emerging with the approved CDK4/6 inhibitors leading to progression in patients with breast cancer (Spring, 2019; Knudsen, 2020). Therefore, the unmet medical need supports development of the next (third) generation CDK4/6 inhibitors in advanced HR+/HER- breast cancer. The ~~dual~~ inhibitory effect of ON 123300 may provide a therapeutic strategy to optimize efficacy of CDK 4/6 inhibition and reduce emergence of resistance.

We believe ON 123300 has ~~the most~~a favorable ~~IC50 value~~kinase inhibitory profile in comparison to the approved CDK4/6 inhibitors (palbociclib, ribociclib, and abemaciclib) and highest single agent cytotoxicity (Perumal, 2016, Divakar, 2016).

Based on data from continuous dosing studies in rats and monkeys the safety profile of ON 123300 is anticipated to be similar to the approved CDK4/6 inhibitors with myelosuppression and gastrointestinal toxicity being most common. Management of these adverse events ~~will~~is expected to follow that used for the approved CDK 4/6 inhibitors. We believe that the proposed mechanism of action of ON 123300, the unmet medical need of the advanced cancers potentially targeted by ON 123300 and the anticipated safety profile of ON 123300 as seen in pre-clinical studies, support conducting ~~a first in human~~ Phase 1 ~~study as rational next step.~~clinical studies.

Clinical development of ON 123300 for both breast cancer as well as other solid tumors in clinical trials is warranted based on the preclinical in vitro studies as well as the xenograft models.

In addition, preliminary efficacy data support the preclinical ~~study is also currently investigating~~observation of rigosertib augmenting the response to checkpoint inhibition (CPI) in patients who had previously failed all standard of care treatment, including CPI. We look forward to the presentation of preliminary data at the upcoming 3rd Annual RAS Targeted Drug Development Summit taking place September 21-23, 2021, and at a future major medical meeting as the data mature.

On June 17, 2021, we announced a publication in Molecular Cancer (Yan, C., Saleh, N., Yang, J. et al. Novel induction of CD40 expression by tumor cells with RAS/RAF/PI3K pathway inhibition augments response to checkpoint blockade. Mol Cancer20, 85; 2021) demonstrating that rigosertib synergistically combined with CPI to improve tumor growth inhibition and survival in a murine melanoma model that did not respond to CPI alone. Rigosertib’s anti-cancer activity was due to its ability to reverse immunosuppressive tumor microenvironments. This pre-clinical data support the clinical evaluation of rigosertib in ~~clear cell renal carcinoma (ccRCC).An~~combination with checkpoint inhibitors.

Rare Disease Program in ~~"RASopathies"~~“RASopathies”

Based on the mechanism of action data published in the journal Cell in 2016, we ~~have~~ initiated a collaborative development program focusing on a group of rare diseases with a ~~well-defined~~well- defined molecular basis in expression or defects involving the Ras effector pathways. Since RASopathies are rare congenital diseases affecting young children, we embarked on a multifaceted collaborative program involving patient advocacy, government and academic organizations. RASopathies are usually caused by germline mutations in genes that alter the RAS subfamily and mitogen-activated protein kinases (MAPK) that control signal transduction and are among the most common genetic syndromes. Together, this group of diseases can impact more than 1 in 1,000 individuals, according to RASopathies.Net.

In January 2018, we entered into a Cooperative Research and Development Agreement (CRADA) with the National Cancer Institute (NCI), which is part of the National Institutes of Health (NIH). Under the terms of the CRADA, the NCI initiated and conducted preclinical laboratory studies on rigosertib in pediatric cancer associated RASopathies. As part of the CRADA, we provided rigosertib and initial funding towards the non-clinical studies. The NCI has conducted ~~studies in~~ preclinical studies of with cell lines from two pediatric solid tumors (rhabdomyosarcoma and neuroblastoma), including xenograft models. For both tumor cell lines, in vitro rigosertib exposure was associated with reduced cell viability associated with destabilization of microtubules, mitotic arrest and apoptosis. In a rhabdomyosarcoma xenograft model, rigosertib treatment ~~had a~~ delayed time to tumor progression and prolonged survival in the animals treated with rigosertib. (Kowalczyk, 2020)

Studies using leukemia cells from the rare childhood RASopathy, known as Juvenile Myelomonocytic Leukemia (JMML), have been conducted. In preliminary in vitro studies performed at Notable Labs, JMML cell killing was observed following rigosertib exposure. Murine xenograft studies performed at the University of California, San Francisco and funded through the Leukemia Lymphoma Society, evaluated rigosertib in this Ras-mutated disease. ~~The results from these pre-clinical studies were equivocal.~~ Further studies with JMML and rigosertib are under consideration.

~~COVID-19 Disease~~
~~In July 2020, based on initial in vitro data suggesting that rigosertib~~ ~~inhibited the replication of SARS-CoV-2 and~~ rigosertib alone induces the dysregulation of RIG-I like receptor signaling (anti-viral defense pathway) and T cell exhaustion signaling in BW-90 cells (Silverman, Blood, Abstract # 4231, 2019), we submitted applications with the National Institute of Allergy and Infectious Disease (NIAID) and a separate application to the Biomedical Advanced Research and Development Authority (BARDA), with the goal of obtaining funding from the National Institutes of Health (NIH) to conduct human studies with rigosertib in COVID-19 patients. Based on the reported mechanism of action which modulates the RAS/RAF/MEK/ERK pathway involved in proliferative signaling, we believe rigosertib may play an important role in inhibiting COVID-19 replication in human cells and specifically lung tissue, which is a primary source of serious disease. We await responses to these submissions. Subsequently, other laboratories have studied rigosertib in COVID-19 models but were unable to replicate the results of the initial study. These preclinical studies are continuing in additional laboratories. We do not plan to begin clinical trials of rigosertib in patients with COVID-19, unless we receive funding.
As of now, some of our programs such as the development of briciclib and recilisib have been discontinued. Some of the studies on our compounds ON 123300 and rigosertib remain ongoing and conclusions and next steps will evolve as more data becomes available.

Critical Accounting Policies and Significant Judgments and Estimates

This management’s discussion and analysis of our financial condition and results of operations is based on our interim unaudited consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities in our consolidated financial statements. On an ongoing basis, we evaluate our estimates and judgments, including those related to accrued expenses, revenue recognition, deferred revenue and stock-based compensation. We base our estimates on historical experience, known trends and events and various other factors that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources.

Change in fair value of warrant liability

The fair value of the warrant liability decreased $427,000 for the three months ended June 30, 2021, compared to an increase of $56,000 for the three months ended June 30, 2020. This change was caused by a decrease in the 2021 period of the fair market value of the warrants issued in our rights offering in 2016. These warrants expired in July 2021.

Other income (expense), net

Other income (expense), net, was a $13,000 loss for the three months ended June 30, 2021 and $0 for the three months ended June 30, 2020. The change of $13,000 was due to $6,000 lower net interest income in the 2021 period and $7,000 higher foreign currency exchange losses in the 2021 period.

Revenues

Revenues increased by $5,000, or 5%, for the six months ended June 30, 2021 when compared to the same period in 2020 because of a clinical supply credit from SymBio in the 2020 period.

General and administrative expenses

General and administrative expenses increased by $0.7 million, or 15%, to $5.1 million for the six months ended June 30, 2021 from $4.4 million for the six months ended June 30, 2020. The increase was attributable primarily to $1.1 million of expenses for investor relations, proxy solicitation, and fees related to our special meeting by proxy in the 2021 period, to $0.1 million higher personnel related costs, and also to $0.2 million higher insurance expenses. These increases were partially offset by $0.3 million lower professional and consulting fees, and $0.4 million of commercial expenses during the 2020 period.

Other income, net, was $73,000 for the three months ended September 30, 2020, and $135,000 for the nine months ended September 30, 2019, due primarily to $40,000 higher foreign exchange expense and $21,000 lower interest income in the 2020 period due to higher interest income and lower foreign exchange loss in the 2019 period.

Liquidity and Capital Resources

Since our inception, we have incurred net losses and experienced negative cash flows from our operations. We incurred net losses of ~~$18.7~~$8.9 million and ~~$15.8~~$12.5 million for the ~~nine~~six months ended ~~September~~June 30, ~~2020~~2021 and ~~2019,~~2020, respectively.

At ~~September~~June 30, ~~2020,~~2021, we had an accumulated deficit of ~~$422.1~~$437.5 million, working capital of ~~$15.7~~$36.7 million, and cash and cash equivalents of ~~$24.2~~$43.7 million. We believe that our cash and cash equivalents as of ~~September~~June 30, ~~2020,~~2021, will be sufficient to fund our operations and ongoing trials ~~into~~for more than eighteen months from the ~~first quarter~~date of ~~2022.~~this filing.

Net cash used in operating activities

Net cash used in operating activities was ~~$17.6~~$11.0 million for the ~~nine~~six months ended ~~September~~June 30, 2021 and consisted primarily of a net loss of $8.9 million, including an increase in the fair value of warrant liability of $0.2 million, and $0.1 million of both noncash stock-based compensation and depreciation expense. Changes in operating assets and liabilities resulted in a net decrease in cash of $2.3 million. Significant changes in operating assets and liabilities included a decrease in prepaid expenses and other current assets of $0.3 million, a decrease in accounts payable and accrued liabilities of $2.5 million due to timing of invoices and payments to our vendors, and a decrease in deferred revenue of $0.1 million due to recognition of the unamortized portion of the upfront payment under our collaboration agreement with SymBio.

Net cash provided by financing activities

Net cash provided by financing activities was ~~$19.1~~$35.7 million and $16.4 million for the ~~nine~~six months ended ~~September~~June 30, 2021 and 2020, ~~resulting~~respectively. The net cash provided by financing activities in the 2021 period resulted from proceeds received from the sales of common stock and ~~warrants and~~ the exercise of warrants. ~~There was $3.4 million of~~The net cash provided by financing activities ~~for~~in the ~~nine months ended September 30, 2019, $3.0~~2020 period of $16.4 million ~~as a result of the proceeds received~~resulted from the ~~sales~~sale of common stock and ~~warrants and~~ the exercise of ~~warrants, and $0.4 million related to the issuance of stock in connection with the HanX rigosertib license transaction.~~warrants.

Operating and Capital Expenditure Requirements

We believe that our cash and cash equivalents of ~~$24.2~~$43.7 million at ~~September~~June 30, ~~2020,~~2021, will be sufficient to fund our operations and ongoing trials ~~into~~for more than eighteen months from the ~~first quarter~~date of 2022. Following the unsuccessful conclusion of the INSPIRE trial, we have taken steps to reduce our cash expenditures. In September 2020, six employees, representing 26% of our staff, were terminated. These employees were primarily associated with the NDA preparation for the use of rigosertib in MDS. On October 30, 2020, we notified our landlord of our intention to not renew our office space lease which expires in February 2021. We are evaluating less expensive space alternatives, including having some or all employees work remotely.

On April 24, 2020, we filed a registration statement on Form S-3 to register $150.0 million of securities. We are exploring various dilutive and non-dilutive sources of funding, including equity and debt financings, strategic alliances, business development and other sources. If we are unable to obtain additional funding, we may not be able to continue as a going concern and may be forced to curtail all of our activities and, ultimately, potentially cease operations. If we are unable to raise sufficient additional funding, we will not have sufficient cash flows and liquidity to fund our planned business operations, and may be forced to limit many, if not all, of our programs and consider other means of creating value for our stockholders, such as licensing to others the development and commercialization of products that we consider valuable and would otherwise likely develop ourselves. Even if we are able to raise additional capital, such financings may only be available on unattractive terms, or could result in significant dilution of stockholders’ interests.this filing. The consolidated financial statements do not include any adjustments relating to recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might be necessary should we be unable to continue in existence.

We have not achieved profitability since our inception and we expect to continue to incur net losses for the foreseeable future. We expect our net cash expenditures in ~~2020~~2021 to be ~~comparable~~lower than they were in 2020, due primarily to ~~2019. If any~~the INSPIRE study being completed in 2020, reductions in our workforce during 2020, and having an earlier clinical stage,

Item 3. Quantitative and Qualitative Disclosures About Market Risk

As a smaller reporting company, the Company is not required to provide the information otherwise required by this Item.

Item 4. Controls and Procedures

Managements’ Evaluation of our Disclosure Controls and Procedures

Our management, with the participation of our principal executive and principal financial officers, evaluated the effectiveness of our disclosure controls and procedures as of ~~September~~June 30, ~~2020.~~2021. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended (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. Based on the evaluation of our disclosure controls and procedures as of ~~September~~June 30, ~~2020,~~2021, our principal executive and principal financial officers concluded that, as of such date, our disclosure controls and procedures were effective.

Changes in Internal Control Over Financial Reporting

Our management, with the participation of our principal executive and principal financial officers, evaluated any changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during our most recently completed fiscal quarter. Based on that evaluation, our principal executive and principal financial officers concluded that no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) occurred during the fiscal quarter ended ~~September~~June 30, ~~2020~~2021 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

Item 1. Legal Proceedings

We are not party to any pending material legal proceedings and are not aware of any such proceedings contemplated by governmental authorities.

Item 1A. Risk Factors

The following risk ~~factors~~factor should be read in conjunction with the “Risk Factors” previously disclosed in our annual report on Form 10-K filed with the SEC on March ~~27, 2020~~18, 2021 and our Quarterly ~~Reports~~Report on Form 10-Q for the ~~quarters~~quarter ended ~~June 30, 2020 and~~ March 31, ~~2020.~~2021.

~~We may not comply with the Nasdaq continued listing requirements. If we are unable to comply with the continued listing requirements~~32

Table of ~~the Nasdaq Capital Market, our Common Stock could be delisted, which could affect our Common Stock's market price and liquidity and reduce our ability to raise capital.~~Contents

~~We are required to meet certain qualitative and financial tests to maintain the listing of our securities on~~ The Nasdaq Capital Market. As of September 30, 2020, we were not in compliance with the Nasdaq continued listing requirements related to minimum bid price. As of September 30, 2020 we were in compliance with the Nasdaq continued listing requirements related to minimum stockholders' equity; however, at certain times during 2019 and 2018 we were not in compliance with this requirement.

On October 6, 2020, we received a letter from The Nasdaq Capital Market (“Nasdaq”) indicating that we failed to comply with the minimum bid price requirement of Nasdaq Listing Rule 5550(a)(2). Nasdaq Listing Rule 5550(a) (2) requires that companies listed on Nasdaq maintain a minimum closing bid price of at least $1.00 per share.

Under Nasdaq Listing Rule 5810(c)(3)(A), we have a 180 calendar day grace period, or until April 5, 2021, to regain compliance by meeting the continued listing standard. The continued listing standard will be met if the Company’s common stock has a minimum closing bid price of at least $1.00 per share for a minimum of ten consecutive business days during the 180 calendar day grace period.

If we are not in compliance by April 5, 2021, we may be afforded a second 180 calendar day period to regain compliance. To qualify, we would be required to meet the continued listing requirement for market value of publicly held shares and all other initial listing standards for The Nasdaq Capital Market, except for the minimum bid price requirement. In addition, we would be required to notify Nasdaq of our intention to cure the minimum bid price deficiency during the second compliance period, by effecting a reverse stock split, if necessary.

~~If we do not regain compliance within the allotted compliance period(s),~~COVID-19 pandemic, including ~~any extensions~~new variants that may be ~~granted by Nasdaq, Nasdaq will provide notice that the Company’s common stock will be subject to delisting. At that time, we may appeal the Nasdaq Staff’s determination to a Nasdaq Hearings Panel.~~

~~We intend to monitor the closing bid price of the Company’s common stock and consider our available options to resolve the noncompliance with the minimum bid price requirement.~~

~~There can be no assurance that we will be able to regain compliance with the minimum bid price requirement or will otherwise be in compliance with other Nasdaq listing criteria.~~

~~If we are unable to maintain compliance with the continued listing requirements of the Nasdaq Capital Market, our Common Stock could be delisted, making it could be~~ more ~~difficult to buy or sell our securities and to obtain accurate quotations, and the price of our securities could suffer a material decline. Delisting could also impair our ability to raise capital.~~

~~The COVID-19 pandemic~~contagious, could adversely impact our business, including our clinical trials, drug manufacturing and nonclinical activities.

The COVID-19 virus continues to spread globally and, as of September 2020, has spread to nearly every country and region in the world, including those in which we have active clinical trial sites. The outbreak and government measures taken in response have also had a significant impact, both direct and indirect, on businesses and commerce, as worker shortages have occurred; supply chains have been disrupted; facilities and production have been suspended; and demand for certain goods and services, such as medical services and supplies, has spiked, while demand for other goods and services, such as travel, has fallen. In response to the spread of COVID-19, the majority of our corporate employees and our administrative employees are working remotely. As the COVID-19 pandemic continues to spread around the globe, we may experience disruptions that could severely impact our business, clinical trials, drug manufacturing and nonclinical ~~activities, including:~~

delays or difficulties in enrolling patients in our clinical trials, such as the previous temporary hold of enrollment in the investigator-initiated Phase 1 study of rigosertib in combination with a PD-1 inhibitor for patients with progressive K-Ras mutated non-small cell lung cancer;

~~delays or difficulties in clinical site initiation, including difficulties in recruiting clinical site investigators and clinical site staff;~~

diversion of healthcare resources away from the conduct of clinical trials, including the diversion of hospitals serving as our clinical trial sites and hospital staff supporting the conduct of our clinical trials;

interruption of key clinical trial activities, such as clinical trial site monitoring, due to limitations on travel imposed or recommended by federal or state governments, employers and others or interruption of clinical trial subject visits and study procedures, which may impact the integrity of subject data and clinical study endpoints;

~~interruption or delays in the operations of the FDA or other regulatory authorities, which may impact review and approval timelines;~~

interruption of, or delays in receiving, supplies of our product candidates from our contract manufacturing organizations due to staffing shortages, production slowdowns or stoppages and disruptions in delivery systems;

~~delays in clinical sites receiving the supplies and materials needed to conduct our clinical trials and interruption in global shipping that may affect the transport of clinical trial materials;~~

~~interruptions in nonclinical studies due to restricted or limited operations at our laboratory facility or those of our outsourced service providers;~~

limitations on employee resources that would otherwise be focused on the conduct of our nonclinical studies or clinical trials, including because of sickness of employees or their families or the desire of employees to avoid contact with large groups of people;

~~delays in receiving approval from local regulatory authorities to initiate our planned clinical trials;~~

changes in local regulations as part of a response to COVID-19 which may require us to change the ways in which our clinical trials are conducted, which may result in unexpected costs, or to discontinue the clinical trials altogether;

delays in necessary interactions with local regulators, ethics committees and other important agencies and contractors due to limitations in employee resources or forced furlough of government employees;

~~refusal of the FDA to accept data from clinical trials in affected geographies outside the United States; and~~

~~interruption or delays to our discovery and development pipeline.~~

~~In addition,~~activities. These potential disruptions may include but are not limited to delays or difficulties in clinical site initiation and patient recruitment, patient withdrawals, postponement of planned clinical or preclinical studies, redirection of site resources from studies, study modification, suspension, or termination, the ~~spread~~introduction of ~~COVID-19~~remote study procedures and modified informed consent procedures, study site changes, direct delivery of investigational products to patient homes requiring state licensing, study deviations or noncompliance, diversion of healthcare resources away from the conduct of clinical trials, including the diversion of hospitals serving as our clinical trial sites and hospital staff supporting the conduct of our clinical trials, delays in receiving approval from local regulatory authorities to initiate our planned clinical trials, and changes or delays in site monitoring. The foregoing may require that we consult with relevant review and ethics committees, IRBs, and the FDA. The foregoing may also impact the ~~trading price of shares~~integrity of our ~~common stock~~study data. The effects of the COVID-19 pandemic may also increase the need for clinical trial patient monitoring and ~~could further severely~~regulatory reporting of adverse effects.

The COVID-19 pandemic may also impact our ability to ~~raise additional capital~~obtain supplies of our product candidates or other materials that may be necessary for the conduct of our development program. If any of our suppliers are adversely impacted by the COVID-19 pandemic or the restrictions resulting from the outbreak, if they cannot obtain the necessary supplies, or if such third parties need to prioritize other products or customers over us, including under the Defense Production Act, we may experience delays or disruptions in our supply chain, which could have a material and adverse impact on our business. Third party manufacturers may also need to implement measures and changes, or deviate from typical requirements because of the COVID-19 pandemic that may otherwise adversely impact our supply chains or the quality of the resulting products or supplies. Depending on the change, we may need to obtain FDA pre-approval or otherwise provide FDA with a ~~timely basis~~notification of the change.

The pandemic could further impact our ability to interact with the FDA or ~~at all.~~other regulatory authorities and obtain any necessary inspections. Due to the potential impact of the COVID -19 outbreak on clinical trials, drug development, and manufacturing, FDA issued a number of guidance documents concerning how sponsors and investigators may address these challenges. FDA has also issued guidance on the development of products to treat COVID-19. FDA’s guidance is continually evolving.

The COVID-19 pandemic may also result in changes in laws and regulations. By example, in March 2020, the U.S. Congress passed the Coronavirus Aid, Relief, and Economic Security Act, or CARES Act, which includes various provisions regarding FDA drug shortage reporting requirements, as well as provisions regarding supply chain security, such as risk management plan requirements, and the promotion of supply chain redundancy and domestic manufacturing. This and any future changes in law may require that we change our internal processes and procedures to ensure continued compliance.

The COVID-19 pandemic continues to rapidly evolve. The extent to which the COVID-19 may impact our business, including our drug manufacturing, nonclinical activities, clinical trials and financial condition will depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the ultimate geographic spread of the disease, the duration of the pandemic, travel restrictions and social distancing in the United States and other countries, business closures or business disruptions and the effectiveness of actions taken in the United States and other countries to contain and treat the disease.

To the extent the COVID-19 pandemic adversely affects our business and financial results, it may also have the effect of heightening many of the other risks described in this section and in the “Risk Factors” section of our Annual Report on Form 10-K for the year ended December 31, 2019 and our Quarterly Reports on Form 10-Q for the quarters ended March 31, 2020, June 30, 2020 and September 30, 2020.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

~~Grants of PSUs and SARs~~Not applicable.

On July 9, 2020, the compensation committee of the board of directors and the board approved a cash bonus program of cash-settled stock appreciation right (“SAR”) awards and cash-settled performance stock unit (“PSU”) awards to the Company’s employees. An aggregate of SAR awards with respect to 3,850,700 shares of common stock and PSU awards with respect to 1,863,300 shares of common stock were granted to the Company’s employees. The SAR awards will be settled in cash, vest 33% on the first anniversary of the date of grant, and the remaining 67% monthly over the next 24 months, have a per-share base amount of $0.56, which was the closing sales price of a share of the Company’s common stock on the grant date, and are in all cases subject to the terms and conditions of the Company’s form of SAR award agreement. The PSU awards vest 50% upon the submission of a new drug application (“NDA”) to the U.S. FDA for rigosertib in higher-risk myelodysplastic syndromes (“HR-MDS”) and 50% upon U.S. FDA approval of rigosertib for HR-MDS. The PSU awards have a maximum value of $1.44 per share. The maximum price per share is the per-share value based on the Company’s market capitalization at $250 million and the Company’s outstanding shares of common stock, which was 174,177,448 shares on July 9, 2020. In all cases, the PSU awards are subject to the terms and conditions of the Company’s form of PSU award agreement.

In addition, on July 9, 2020, based on the recommendation of the compensation committee, the board approved a change in the non-employee director compensation policy that would provide for an annual SAR award with respect to 125,000 shares of common stock for each of the Company’s non-employee directors. No other changes to the non-employee director compensation policy were approved and, on July 9, 2020, the Board approved the initial 125,000 SAR award to each of the non-employee directors. The SAR awards vest on the first anniversary of grant subject to the director’s continued service and will be settled in cash, have a per-share base amount of $0.56, and are in all cases subject to the terms and conditions of the Company’s form of SAR award agreement.

Each SAR subject to an SAR award represents the right to a cash payment equal to the excess, if any, of (i) the fair market value of each underlying share of the Company’s common stock, determined on the date of exercise of the SAR minus (ii) the base amount. Pursuant to the terms of the SAR awards, in no event may the cash payment for each SAR exceed $0.88, which is the maximum price per share of $1.44, minus the base amount of $0.56, subject to adjustment in accordance with the terms of the Stock Appreciation Right Award Agreement. The maximum price per share is the per-share value based on the Company’s market capitalization at $250 million and the Company’s outstanding shares of common stock, which was 174,177,448 shares on July 9, 2020.

The issuances of the securities described above were not registered under the Securities Act because they were made in transactions exempt from registration under Section 4(a)(2) of the Securities Act and/or Rule 506 promulgated thereunder.
