Notes to Unaudited Financial Statement s

​

1. Description of the Business

​

GlycoMimetics, Inc. (the Company), a Delaware corporation headquartered in Rockville, Maryland, was incorporated in 2003. The Company is a late clinical-stage biotechnology company focused on improving the lives of people living with cancer and inflammatory diseases by leveraging the inhibition of carbohydrate interactions that occur on the surface of cells. The Company is developing a pipeline of proprietary glycomimetics, which are small molecules that mimic the structure of carbohydrates involved in important biological processes, to inhibit disease-related functions of carbohydrates such as the roles they play in cancers and inflammation.

​

2. Going Concern

​

The accompanying unaudited financial statements have been prepared assuming that the Company will continue as a going concern within one year after the date that the financial statements are issued. During 2023, the Company incurred a net loss of $36.9 million and had net cash flows used in operating activities of $34.9 million. At March 31, 2024, the Company had $31.3 million in cash and cash equivalents and had no committed source of additional funding from either debt or equity financings, although the Company may, at its discretion, sell equity securities under the terms of its existing at-the-market sales agreement (see Note 7), subject to certain conditions and limitations. Management believes that given the Company’s current cash position and forecasted negative cash flows from operating activities over the next twelve months, including the continuation of our product development activities, there is substantial doubt about its ability to continue as a going concern after the date that is one year from the date that these unaudited financial statements are issued, without obtaining additional financing or entering into another form of non-equity or debt arrangement.

The Company’s ability to fund its operations is dependent upon management’s plans, which include reducing operating expenses and raising additional capital in the near term primarily through a combination of equity and debt financings, collaborations, strategic alliances and marketing, distribution or licensing arrangements and in the longer term, from revenue related to product sales, to the extent its product candidates receive marketing approval and can be commercialized. There can be no assurances that new financings or other transactions will be available to the Company on commercially acceptable terms, or at all. Also, any collaborations, strategic alliances and marketing, distribution or licensing arrangements may require the Company to give up some or all of its rights to a product or technology, which in some cases may be at less than the full potential value of such rights. If the Company is unable to obtain additional capital, the Company will assess its capital resources and may be required to delay, reduce the scope of or eliminate some or all of its operations, which may have a material adverse effect on its business, financial condition, results of operations and ability to operate as a going concern.

The financial statements do not include any adjustments that might be necessary if the Company is not able to continue as a going concern.

​

3. Significant Accounting Policies

​

There have been no material changes to the significant accounting policies previously disclosed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the United States Securities and Exchange Commission (the SEC) on March 27, 2024 (the Form 10-K).

​

Basis of Accounting

​

The accompanying unaudited financial statements were prepared based on the accrual method of accounting in accordance with U.S. generally accepted accounting principles (GAAP).

Unaudited Financial Statements

​

The accompanying balance sheet as of March 31, 2024, statements of operations and comprehensive loss and stockholders’ equity for the three months ended March 31, 2024 and 2023 and statements of cash flows for the three months ended March 31, 2024 and 2023 are unaudited. These unaudited financial statements have been prepared in accordance with the rules and regulations of the SEC for interim financial information. Accordingly, they do not include all of the information and footnotes required by GAAP for complete annual financial statements. These unaudited financial statements should be read in conjunction with the audited financial statements and the accompanying notes for the year ended December 31, 2023 contained in the Form 10-K. The unaudited interim financial statements have been prepared on the same basis as the annual financial statements and in the opinion of management reflect all adjustments (consisting of normal recurring adjustments) necessary to state fairly the Company’s financial position as of March 31, 2024, its results of operations and changes in its stockholders’ equity for the three months ended March 31, 2024 and 2023 and its cash flows for the three months ended March 31, 2024 and 2023. The December 31, 2023 balance sheet included herein was derived from audited financial statements, but does not include all disclosures including notes required by GAAP for complete annual financial statements. The financial data and other information disclosed in these notes to the financial statements related to the three months ended March 31, 2024 and 2023 are unaudited. Interim results are not necessarily indicative of results for an entire year or for any future period.

​

Use of Estimates

​

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Although actual results could differ from those estimates, management does not believe that such differences would be material.

​

​

Fair Value Measurements

​

The Company had no assets or liabilities that were measured using quoted prices for similar assets and liabilities or significant unobservable inputs (Level 2 and Level 3 assets and liabilities, respectively) as of March 31, 2024 and December 31, 2023. The carrying value of cash held in money market funds of $25.2 million and $38.8 million as of March 31, 2024 and December 31, 2023, respectively, is included in cash and cash equivalents and approximates market values based on quoted market prices (Level 1 inputs). The Company did not transfer any assets measured at fair value on a recurring basis between levels during the three months ended March 31, 2024 and 2023.

​

Concentration of Credit Risk

​

Credit risk represents the risk that the Company would incur a loss if counterparties failed to perform pursuant to the terms of their agreements. Financial instruments that potentially expose the Company to concentrations of credit risk consist primarily of cash and cash equivalents. The Company maintains its cash balances with financial institutions in federally insured accounts and has cash balances in excess of the insurance limits. Cash equivalents consist of investment in United States government money market funds with major financial institutions. These deposits and funds may be redeemed upon demand and the Company does not anticipate any losses on such balances. The Company has not experienced any losses to date and believes that it is not exposed to any significant credit risk on cash and cash equivalents.

​

Revenue Recognition

​

The Company applies Accounting Standards Codification, or ASC, Topic 606, Revenue from Contracts with Customers (Topic 606), to all contracts with customers, except for contracts that are within the scope of other standards, such as leases, insurance, collaboration arrangements and financial instruments. Under Topic 606, an entity recognizes revenue when its customer obtains control of promised goods or services in an amount that reflects the consideration which the entity expects to receive in exchange for those goods and services. To determine revenue recognition for arrangements that an entity determines are within the scope of Topic 606, the entity performs the following five steps: (i) identify the contract(s) with the customer(s); (ii) identify the performance obligations in the contract; (iii) determine the

8

Table of Contents

transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation. The Company only applies the five-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods and services it transfers to the customer. At contract inception, the Company assesses the goods or services promised within each contract that falls under the scope of Topic 606, determines those that are performance obligations and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied.

The Company enters into licensing agreements which are within the scope of Topic 606, under which it licenses certain of its drug candidates’ rights to third parties. The terms of these arrangements typically include payment of one or more of the following: non-refundable, up-front license fees; development, regulatory and commercial milestone payments; and royalties on net sales of the licensed product, if and when earned. See Note 10 for additional information regarding the Company’s license agreements.

In determining the appropriate amount of revenue to be recognized as it fulfills its obligation under each of its agreements, the Company performs the five steps under Topic 606 described above. As part of the accounting for these arrangements, the Company must develop assumptions that require judgment to determine the stand-alone selling price, which may include forecasted revenues, development timelines, reimbursement of personnel costs, discount rates and probabilities of technical and regulatory success.

Licensing of Intellectual Property: If the license to the Company’s intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes revenue from non-refundable, up-front fees allocated to the license when the license is transferred to the licensee and the licensee is able to use and benefit from the license. For licenses that are bundled with other promises, the Company utilizes judgment to assess the nature of the combined performance obligation to determine whether the combined performance obligation is satisfied over time or at a point in time and, if over time, the appropriate method of measuring progress for purposes of recognizing revenue from non-refundable, up-front fees. The Company evaluates the measure of progress each reporting period, and, if necessary, adjusts the measure of performance and related revenue recognition.

Milestone Payments: At the inception of each arrangement that includes development milestone payments, the Company evaluates whether the milestones are considered probable of being reached and estimates the amount to be included in the transaction price using the most likely amount method. If it is probable that a significant revenue reversal will not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within the control of the Company or the licensee, such as regulatory approvals, are not considered probable of being achieved until those approvals are received. The transaction price is then allocated to each performance obligation on a relative stand-alone selling price basis, for which the Company recognizes revenue as or when the performance obligations under the contract are satisfied. At the end of each subsequent reporting period, the Company re-evaluates the probability of achievement of such development milestones and any related constraint and, if necessary, adjusts its estimate of the overall transaction price. Any such adjustments are recorded on a cumulative catch-up basis, which would affect license, collaboration and other revenues and earnings in their period of adjustment.

Royalties: For arrangements that include sales-based royalties, including milestone payments based on the level of sales, and for which the license is deemed to be the predominant item to which royalties relate, the Company recognizes revenue at the later of (i) when the related sales occur or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied). To date, the Company has not recognized any royalty revenue from its license agreements.

Manufacturing and Supply: The obligations under the Company’s agreements may include clinical and/or commercial manufacturing products to be provided by the Company to the counterparty. The services are generally determined to be distinct from the other promises or performance obligations identified in the arrangement. The Company recognizes the transaction price allocated to these services as revenue at a point in time when transfer of control of the related products to the customer occurs.

Accruals for Clinical Trial Expenses

​

​

Clinical trial costs primarily consist of expenses incurred under agreements with contract research organizations (CROs), investigative sites, laboratory testing expenses, data management and consultants that conduct the Company's clinical trials. Clinical trial expenses are a significant component of research and development expenses, and the Company outsources a significant portion of these clinical trial activities to third parties. The accrual for site and patient costs includes inputs such as estimates of patient enrollment, patient cycles incurred, clinical site activations, estimated project duration and other pass-through costs. These inputs are required to be estimated due to a lag in receiving the actual clinical information from third parties. Payments for these activities are based on the terms of the individual arrangements, which may differ from the pattern of costs incurred, and are reflected on the balance sheets as a prepaid asset or accrued expenses. These third-party agreements are generally cancellable, and related costs are recorded as research and development expenses as incurred. Except for payments made in advance of services, clinical trial costs are expensed as incurred. Non-refundable advance clinical payments for goods or services that will be used or rendered for future research and development activities are recorded as a prepaid asset and recognized as expense as the related goods are delivered or the related services are performed. When evaluating the adequacy of the accrued expenses, management assessments include: (i) an evaluation by the project manager of the work that has been completed during the period; (ii) measurement of progress prepared internally and/or provided by the third-party service provider; (iii) analyses of data that justify the progress; and (iv) the Company’s judgment. Significant judgments and estimates may be made in determining the accrued balances at the end of any reporting period. Actual results could differ from the estimates made. The Company’s historical clinical accrual estimates have not been materially different from the actual costs.

Stock-Based Compensation

​

Stock-based payments are accounted for in accordance with the provisions of ASC 718, Compensation—Stock Compensation. The fair value of stock-based payments is estimated, on the date of grant, using the Black-Scholes-Merton model. The resulting fair value is recognized ratably over the requisite service period, which is generally the vesting period of the option. The Company accounts for forfeitures as they occur.

​

The Company has elected to use the Black-Scholes-Merton option pricing model to value any options granted. The Company will reconsider use of the Black-Scholes-Merton model if additional information becomes available in the future that indicates another model would be more appropriate or if grants issued in future periods have characteristics that prevent their value from being reasonably estimated using this model.

​

A discussion of management’s methodology for developing some of the assumptions used in the valuation model follows:

​

Expected Dividend Yield—The Company has never declared or paid dividends and has no plans to do so in the foreseeable future.

​

Expected Volatility—Volatility is a measure of the amount by which a financial variable such as share price has fluctuated (historical volatility) or is expected to fluctuate (expected volatility) during a period. The Company bases the expected volatility on the historical volatility of the Company’s publicly traded common stock.

​

Risk-Free Interest Rate—This is the U.S. Treasury rate for the week of each option grant during the year, having a term that most closely resembles the expected life of the option.

​

Expected Term—This is a period of time that the options granted are expected to remain unexercised. Options granted have a maximum term of 10 years. The Company estimates the expected life of the option term to be 6.25 years. The Company uses a simplified method to calculate the average expected term.

​

Net Loss Per Common Share

​

Basic net loss per common share is determined by dividing net loss by the weighted-average number of common shares outstanding during the period, without consideration of common stock equivalents. Diluted net loss per share is computed by dividing net loss by the weighted-average number of common stock equivalents outstanding for the period.

The treasury stock method is used to determine the dilutive effect of the Company’s stock options and restricted stock units (RSUs).

​

The following potentially dilutive securities outstanding have been excluded from the computation of diluted weighted-average common shares outstanding, as they would be anti-dilutive:

​ | 2024 |  | 2023 |
Stock options and RSUs | 13,546,834 |  | 11,420,012 |

​

Comprehensive Loss

Comprehensive loss comprises net loss and other changes in equity that are excluded from net loss. For the three months ended March 31, 2024 and 2023, the Company’s net loss equaled comprehensive net loss and, accordingly, no additional disclosure is presented.

6. Operating Leases

At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the circumstances present. The Company determines a lease exists if the contract conveys the right to control an identified asset for a period of time in exchange for consideration. Control is considered to exist when the lessee has the right to obtain substantially all of the economic benefits from the use of an identified asset as well as direct the right to use of that asset. Leases with a term greater than one year are recognized on the balance sheet as right-of-use assets, lease liabilities and, if applicable, long-term lease liabilities. The Company has elected not to recognize on the balance

11

Table of Contents

sheet leases with terms of one year or less on the lease commencement date. If a contract is considered to be a lease, the Company recognizes a lease liability based on the present value of the future lease payments over the expected lease term, with an offsetting entry to recognize a right-of-use asset. The Company has also elected to use the practical expedient and account for each lease component and related non-lease component as one single component. The lease component results in a right-of-use asset being recorded on the balance sheet and amortized as lease expense on a straight-line basis.

The interest rate implicit in lease contracts is typically not readily determinable. As such, the Company utilizes the appropriate incremental borrowing rate, which is the rate incurred to borrow on a collateralized basis over a term similar to the term of the lease for which the rate is estimated. Certain adjustments to the right-of-use asset may be required for items such as initial direct costs paid or incentives received.

The Company leases office and research space in Rockville, Maryland under an operating lease that is subject to annual rent increases (the Lease). The Company paid a security deposit of $52,320 to be held until the expiration or termination of the Company’s obligations under the Lease. In April 2023, the Company and its landlord entered into an amendment to the Lease (the Lease Amendment). Pursuant to the Lease Amendment, the Company and the landlord agreed that the lease term for a portion of the premises, consisting of approximately 30,000 square feet, would be extended from November 1, 2023 to January 31, 2025. The Company’s lease of the remaining premises, consisting of approximately 12,000 square feet, expired on October 31, 2023. There were no additional operating leases entered into during the quarter ended March 31, 2024.

The components of lease expense and related cash flows were as follows:

​

​ | ​ | ​ | ​ | ​ | ​
​ | Three Months Ended March 31,

​

At-The-Market Sales Facility

​

In March 2022, the Company filed a shelf registration statement with the SEC, which was declared effective on April 22, 2022. On April 28, 2022, the Company entered into an at-the-market sales agreement (the 2022 Sales Agreement) with Cowen and Company, LLC. Under the 2022 Sales Agreement, the Company may sell up to $100.0 million worth of shares of common stock. During the quarter ended March 31, 2023, the Company issued and sold 9,822,930 shares of common stock under the 2022 Sales Agreement at a weighted average price per share of $3.01, for aggregate net proceeds of $28.7 million, after deducting commissions and offering expenses. There were no shares issued under the 2022 Sales Agreement during the quarter ended March 31, 2024. As of March 31, 2024, approximately $66.0 million remained available to be sold under the terms of the 2022 Sales Agreement.

8. Stock-based Compensation

2013 Equity Incentive Plan

​

The Company’s board of directors adopted, and its stockholders approved, its 2013 Equity Incentive Plan effective in January 2014, and the 2013 Equity Incentive Plan was amended and restated by approval of the board of directors in April 2022 and by approval of the stockholders in May 2022 (as so amended and restated, the 2013 Plan). The 2013 Plan provides for the grant of incentive stock options, within the meaning of Section 422 of the Internal Revenue Code (the Code), to the Company’s employees and its parent and subsidiary corporations’ employees, and for the grant of nonstatutory stock options, restricted stock awards, restricted stock unit awards (RSUs), stock appreciation rights, performance stock awards and other forms of stock compensation to its employees, including officers, consultants and directors. The 2013 Plan also provides for the grant of performance cash awards to the Company’s employees, consultants and directors. Unless otherwise stated in a stock option agreement, 25% of the shares subject to an option grant will typically vest upon the first anniversary of the vesting start date and thereafter at the rate of one forty-eighth of the option shares per month as of the first day of each month after the first anniversary. Upon termination of employment by reasons other than death, cause, or disability, any vested options shall terminate 90 days after the termination date, unless otherwise set forth in a stock option agreement. Stock options generally terminate 10 years from the date of grant.

​

Authorized Shares

​

The maximum number of shares of common stock that may be issued under the 2013 Plan was originally 1,000,000 shares, plus any shares subject to stock options or similar awards granted under the 2003 Plan that expire or terminate without having been exercised in full or are forfeited to or repurchased by the Company. Upon the amendment and restatement of the 2013 Plan in May 2022, the existing share reserve was increased by 2,619,622. Beginning on January 1, 2023 and ending on (and including) January 1, 2029, the maximum number of shares of common stock that may be issued under the 2013 Plan will cumulatively be increased by 4% of the number of shares of common stock issued and outstanding on the immediately preceding December 31, or such lesser number of shares as determined by the board of directors or the compensation committee thereof. The maximum number of shares that may be issued pursuant to exercise of incentive stock options under the 2013 Plan is 20,000,000 shares. As of March 31, 2024, the total number of shares reserved for issuance under the 2013 Plan was 14,257,627 shares, of which 2,597,377 shares were available for future grants.

​

Shares issued under the 2013 Plan may be authorized but unissued or reacquired shares of common stock. Shares subject to stock awards granted under the 2013 Plan that expire or terminate without being exercised in full, or that are paid out in cash rather than in shares, will not reduce the number of shares available for issuance under the 2013 Plan. Additionally, shares issued pursuant to stock awards under the 2013 Plan that the Company repurchases or that are forfeited, as well as shares reacquired by the Company as consideration for the exercise or purchase price of a stock award or to satisfy tax withholding obligations related to a stock award, will become available for future grant under the 2013 Plan.

​

As of March 31, 2024, there was $10,785,346 of total unrecognized compensation expense related to unvested options under the 2013 Plan that will be recognized over a weighted-average period of approximately 3.5 years. Total intrinsic value of the options exercised during the three months ended March 31, 2024 and 2023 was $3,758 and $23,760, respectively and total cash received for options exercised was $4,898 and $33,768, respectively. The total fair value of stock options which vested in the three months ended March 31, 2024 and 2023 was $1,394,896 and $704,311, respectively.

​

The Company has granted stock options to purchase an aggregate of 151,900 shares to certain employees under the 2013 Plan, the vesting of which is subject to performance vesting conditions relating to the achievement of specified regulatory or commercial milestones. The maximum fair value of $133,820 associated with performance-based options granted has been excluded from the unrecognized compensation expense under the 2013 Plan as the completion of the performance milestones was not deemed to be probable as of March 31, 2024. The Company will reevaluate at the end of each reporting period the probability that the performance conditions will be achieved and will record any adjustments to the compensation cost at that time.

​

An RSU is a stock award that entitles the holder to receive shares of the Company’s common stock as the award vests. The fair value of each RSU is based on the closing price of the Company’s common stock on the date of grant. In January 2021, the Company awarded RSUs under the 2013 Plan to all of its employees. The RSUs granted vest over four years in equal installments on each anniversary of the grant date, provided that the employee remains employed by the Company at the applicable vesting date. Compensation expense is recognized on a straight-line basis. As of March 31, 2024, there was $179,660 of total unrecognized compensation expense associated with outstanding RSU grants that will be recognized over a weighted-average period of approximately 0.8 years.

​

The following is a summary of RSU activity under the 2013 Plan for the three months ended March 31, 2024:

Issuance of Shares to Directors in Lieu of Cash Retainers for Service

In March 2023, the Company’s board of directors amended the Company’s Non-Employee Director Compensation Policy to include an election to receive unrestricted shares of common stock in lieu of quarterly board and committee retainer cash payments. The number of shares to be issued to an electing director is determined on the last day of each fiscal quarter by dividing the dollar amount of the compensation to be paid for such quarter that is subject to the election by the closing price of a share of common stock on the last trading day of the fiscal quarter, rounded up to the nearest

whole share. Non-employee directors who made such an election will receive 13,127 shares of common stock in lieu of cash compensation earned for the quarter ended March 31, 2024. All shares of common stock issued pursuant to such an election are fully vested upon issuance and are classified as “Other Awards” under the 2013 Plan.

Inducement Plan

​

The Company’s board of directors previously adopted the GlycoMimetics, Inc. Inducement Plan (as amended to date, the Inducement Plan). The Inducement Plan provides for the grant of nonstatutory stock options, restricted stock awards, RSU awards, stock appreciation rights and other forms of stock awards to individuals not previously an employee or director of the Company as an inducement for such individuals to join the Company. Unless otherwise stated in an applicable stock option agreement, one-fourth of the shares subject to an option grant under the Inducement Plan will typically vest upon the first anniversary of the vesting start date, with the balance of the shares vesting in a series of thirty-six successive equal monthly installments as of the first day of each month measured from the first anniversary of the vesting start date, subject to the new employee’s continued service with the Company through the applicable vesting dates. Upon termination of employment by reasons other than death, cause or disability, any vested options will terminate 90 days after the termination date, unless otherwise set forth in a stock option agreement. Stock options generally terminate 10 years from the date of grant. The Inducement Plan was amended by the board of directors on multiple occasions to increase the number of shares reserved for issuance to 3,000,000 shares as of March 31, 2024. As of March 31, 2024, there were 269,508 shares available for future grants under the Inducement Plan.

​

A summary of the Company’s stock option activity under the Inducement Plan for the three months ended March 31, 2024 is as follows:

Exercisable as of March 31, 2024 | ​ | 1,060,375 | ​ | ​ | 1.98 | ​ | 7.5 | ​ | ​ | 1,135

​

As of March 31, 2024, there was $1,621,972 of total unrecognized compensation expense related to unvested options under the Inducement Plan that will be recognized over a weighted-average period of approximately 2.5 years. The total fair value of stock options which vested in the three months ended March 31, 2024 and 2023 was $305,219 and $181,032, respectively. There were no options exercised under the Inducement Plan during the three months ended March 31, 2024 and 2023.

​

The Company has granted stock options to purchase an aggregate of 584,200 shares to certain newly hired employees under the Inducement Plan which options are subject to performance-based vesting conditions. The maximum fair value of $825,353 associated with the performance-based options has been excluded from the unrecognized compensation expense under the Inducement Plan as the completion of the performance milestones was not deemed to be probable as of March 31, 2024. The Company will reevaluate at the end of each reporting period the probability that the performance conditions will be achieved and will record any adjustments to the compensation cost at that time.

9. Income Taxes

The Company did not record any tax provision or benefit for the three months ended March 31, 2024 and 2023. The Company has provided a valuation allowance for the full amount of its net deferred tax assets since realization of any future benefit from deductible temporary differences, net operating loss carryforwards and research and development credits is not more-likely-than-not to be realized at March 31, 2024 and December 31, 2023.

10. License and Collaboration Agreements

​

Apollomics

​

In 2020, the Company entered into a collaboration and license agreement (the Agreement) with Apollomics (Hong Kong), Limited (Apollomics) for the development, manufacture and commercialization of products derived from two of the Company’s compounds, GMI-1271 and GMI-1687 (the Products) for therapeutic and prophylactic uses (the Field) in China, Taiwan, Hong Kong and Macau (the Territory). Under the terms of the Agreement, the Company granted Apollomics:

| ● | an exclusive license, with the right to sublicense, to develop, manufacture and have manufactured, distribute, market, promote, sell, have sold, offer for sale, import, label, package and otherwise the Products in the Field in the Territory; and

| ● | a non-exclusive license to conduct preclinical research with respect to Products in the Field outside of the Territory for the purposes of developing such Products for use in the Territory.

​

In 2020, the Company and Apollomics also entered into a clinical supply agreement pursuant to which the Company will manufacture and supply the Products at agreed upon prices. Apollomics has the option to begin manufacture of the Products after appropriate material transfer requirements are met. The Company did not recognize revenue under the clinical supplies agreement during the three months ended March 31, 2024 and 2023.

​

The Company evaluated the Agreement under the provisions of ASC 606 and identified two performance obligations under this revenue arrangement: the (i) delivery of functional licenses and (ii) manufacture and supply of the Products. The initial transaction price consists of a $9.0 million non-refundable up-front payment which was allocated to the delivered functional licenses and recognized in full as revenue in 2020 given that the performance obligation was satisfied upon inception. The Agreement contains various forms of variable consideration, including (i) up to $75.0 million in development milestones based on achievement of certain clinical and regulatory events, (ii) up to $105.0

16

Table of Contents

million of sales-based commercial milestones based on achievement of certain annual net sales targets, (iii) sales-based royalties at specified percentages of net sales ranging from the high single digits to 15%, and (iv) manufacture and supply of clinical and commercial Products. The Company has fully constrained the development milestone consideration using the most likely amount method and will recognize that revenue when it is probable that recognition of revenue related to the milestone will not result in a significant reversal in amounts recognized in future periods, and as such have been excluded from the transaction price. The Company did not recognize any milestone revenue under the Agreement for the three months ended March 31, 2024 and 2023.

The Company will recognize revenue related to the sales-based commercial and royalty milestones and royalties at the later of (i) when the related sales occur or (ii) when the performance obligation to which some or all of the royalty has been allocated has been satisfied (or partially satisfied), as they were determined to relate predominantly to the licenses granted to Apollomics and, therefore, have been excluded from the transaction price. Lastly, the Company has determined that the consideration for the manufacturing and supply is all variable and is fully constrained. Variable consideration allocated to manufacturing and supply will be recognized at a point in time when the Product is delivered and when the title to the Product is transferred to the customer pursuant to the agreement. The Company reassesses the transaction price in each reporting period and upon the occurrence of a change in circumstances or final resolution of any particular event.

​

11. Subsequent Events

​

In April 2024, the Company entered into a purchase commitment with a third-party vendor in the amount of $3,768,000 for 120 kg of raw materials to support manufacturing of its produce candidate uproleselan for commercial supply. Under the agreement, the Company paid a non-refundable advance of $1,130,400 to the vendor. The remainder will be due, if at all, upon completion of the produced quantity.

​

On May 6, 2024, the Company reported topline results from the Company sponsored Phase 3 uproleselan trial, in which uproleselan combined with chemotherapy did not achieve a statistically significant improvement in overall survival in the intent to treat population versus chemotherapy alone. Patients treated with uproleselan had a median overall survival of 13 months, compared to 12.3 months in the placebo arm. Adverse events were consistent with known side effect profiles of chemotherapy used in the trial. The Company has begun to further evaluate the data with medical, statistical, and regulatory experts and plans to submit the full results for presentation at an upcoming medical meeting.

​

Overview

We are a late clinical-stage biotechnology company focused on improving the lives of people living with cancer and inflammatory diseases by leveraging the inhibition of carbohydrate interactions that occur on the surface of cells. We are developing a pipeline of proprietary glycomimetics, which are small molecules that mimic the structure of carbohydrates involved in important biological processes, to inhibit disease-related functions of carbohydrates such as the roles they play in cancers and inflammation. We believe this represents an innovative approach to drug discovery to treat a wide range of diseases. We are focusing our efforts on drug candidates for diseases that we believe will qualify for orphan drug designation.

​

Our lead glycomimetic drug candidate, uproleselan, is a specific E-selectin antagonist that we are developing to be used in combination with chemotherapy to treat patients with acute myeloid leukemia, or AML, a life-threatening hematologic cancer, and potentially other hematologic cancers. In 2021, we completed enrollment of 388 patients in a randomized, double-blind, placebo-controlled Phase 3 pivotal clinical trial to evaluate uproleselan in individuals with relapsed/refractory AML, the design of which was based on guidance received from the FDA.

​

On May 6, 2024, we reported topline results from the trial, in which uproleselan combined with chemotherapy did not achieve a statistically significant improvement in overall survival in the intent to treat population versus chemotherapy alone. Patients treated with uproleselan had a median overall survival of 13 months, compared to 12.3 months in the placebo arm. Adverse events were consistent with known side effect profiles of chemotherapy used in the trial. We have begun to further evaluate the data with medical, statistical, and regulatory experts and plan to submit the full results for presentation at an upcoming medical meeting.

​

We have also entered into a Cooperative Research and Development Agreement, or CRADA, with the National Cancer Institute, or NCI, part of the National Institutes of Health, to conduct a Phase 2/3 randomized, controlled clinical trial testing the addition of uproleselan to a standard chemotherapy regimen. Enrollment of 267 patients in the Phase 2 portion was completed in December 2021. There will be a planned interim analysis that will evaluate event-free survival and whether the pre-specified threshold for continuing to Phase 3 has been met. The trial may also provide support for regulatory filings, if the results of the planned interim analysis are sufficiently positive.

​

In May 2023, the FDA agreed to our initial Pediatric Study Plan, and in October 2023, the European Medicines Agency agreed to our Pediatric Investigational Plan. As part of these pediatric plans, an NCI-sponsored Phase 1/2

18

Table of Contents

pediatric trial is currently being conducted by the Children’s Oncology Group Pediatric Early Phase Clinical Trials Network. The Phase 1 dose escalation study will evaluate the safety and preliminary activity of uproleselan plus fludarabine and high dose cytarabine in pediatric AML patients after two or more prior therapies. Enrollment in the Phase 1 trial is expected to be up to 18 patients. The first patient was enrolled in October 2023.

​

We have rationally designed an innovative antagonist of E-selectin, GMI-1687, that could be a subcutaneously administered treatment. Initially developed as a potential life-cycle extension to uproleselan, we believe that GMI-1687 could be developed to broaden the clinical usefulness of an E-selectin antagonist to conditions where outpatient treatment is preferred or required. In 2022, we filed an IND for GMI-1687 as a potential treatment for vaso-occlusive event (VOE), a common complication of sickle cell disease, and in December 2023, we completed enrollment of 40 subjects in a Phase 1a trial of GMI-1687 in healthy adult volunteers.

​

We are advancing other preclinical-stage programs, including small-molecule glycomimetic compounds that inhibit the protein galectin-3, which we believe may have potential to be an orally administered treatment for fibrosis, cancer and cardiovascular disease. In 2022, we selected a lead galectin drug candidate, GMI-2093, for evaluation in preclinical studies. We are evaluating options for the further development of GMI-2093 as a potential treatment for fibrosis and in oncology indications.

​

We also designed GMI-1359, a drug candidate that simultaneously targets both E-selectin and a chemokine receptor known as CXCR4. We are not currently developing GMI-1359 and are seeking a licensing partner to continue clinical development of this drug candidate.

​

We have financed our operations primarily through private placements of our securities, up-front and milestone payments under our license and collaboration agreements and the net proceeds from public offerings of common stock, including sales of common stock under at-the-market sales facilities with Cowen and Company LLC, or Cowen. We have no approved drugs currently available for sale, and substantially all of our revenue to date has been revenue from up-front and milestone payments under license and collaboration agreements.

​

Since inception, we have incurred significant operating losses. We had an accumulated deficit of $467.2 million as of March 31, 2024 and we expect to continue to incur operating losses over at least the next several years. Our net losses may fluctuate significantly from quarter to quarter and year to year, depending on the timing of our clinical trials and our expenditures on other research and development activities.

​

To fund further operations, we will need to preserve our current cash resources and raise additional capital. We may obtain additional financing in the future through the issuance of our common stock, through other equity or debt financings, potentially including the use of our at-the-market sales facility with Cowen, through collaborations or partnerships with other companies, or through the sale of rights to receive royalties on sales of uproleselan or any other drug candidates. We may not be able to raise additional capital on terms acceptable to us, or at all, and any failure to raise capital as and when needed could compromise our ability to execute on our business plan. Although it is difficult to predict future liquidity requirements, we believe that our existing cash and cash equivalents will be sufficient to fund our operations through the fourth quarter of 2024 without giving effect to potential business development opportunities, such as upfront or milestone payments under license and collaboration agreements, or financing activities including the additional sale of common stock under our at-the-market sales facility or otherwise. We also plan to reduce our operating expenses in the upcoming months in order to preserve capital, although any such efforts are not expected to materially extend the period of time for which our cash resources will be sufficient. Our ability to successfully transition to profitability will be dependent upon achieving a level of revenues adequate to support our cost structure. We cannot assure you that we will ever be profitable or generate positive cash flow from operating activities or that we will not need to reduce the scope of or eliminate some or all of our operations.

​

Our Agreements with Apollomics

In January 2020, we entered into an exclusive collaboration and license agreement with Apollomics (Hong Kong) Limited, or Apollomics, for the development and commercialization of uproleselan and GMI-1687 in Mainland China, Hong Kong, Macau and Taiwan, also known as Greater China. Under the terms of the agreement, Apollomics will be responsible for clinical development and commercialization in Greater China. We will also collaborate with Apollomics

Table of Contents

to advance the preclinical and clinical development of GMI-1687. We received an upfront cash payment of $9.0 million and in September 2020 received a $1.0 million development milestone payment. There were no milestone payments from Apollomics during the quarters ended March 31, 2024 or 2023. Subject to the terms of the agreement, we will be eligible to receive potential further milestone payments totaling approximately $179.0 million, as well as tiered royalties ranging from the high single digits to 15%, as a percentage of net sales. Apollomics will be responsible for all costs related to development, regulatory approvals, and commercialization activities for uproleselan and GMI-1687 in Greater China, and we and Apollomics expect to enter into clinical and commercial supply agreements with respect to our provision of uproleselan and GMI-1687 to Apollomics. We retain all rights for both compounds in the rest of the world.

In September 2020, the China National Medical Products Administration, or NMPA, Center for Drug Evaluation, or CDE, granted IND approval for uproleselan (also known as APL-106), enabling the initiation of a Phase 1 pharmacokinetics and tolerability study and a Phase 3 bridging study of APL-106 in combination with chemotherapy in relapsed/refractory AML. In January 2021, APL-106 was granted Breakthrough Therapy Designation from the China NMPA CDE for the treatment of relapsed/refractory AML. In January 2024, Apollomics announced the completion of enrollment in the Phase 3 bridging study. A total of 140 adult patients across 20 sites in Greater China with primary refractory AML or relapsed AML (first or second untreated relapse) and eligible to receive induction chemotherapy were randomized to receive either uproleselan combined with chemotherapy or placebo plus chemotherapy. The primary endpoint for the Phase 3 bridging study is overall survival. Secondary outcome measures include the rate and duration of remission and whether uproleselan can reduce the rate of oral mucositis, a chemotherapy-related side effect.

​

In June 2020, we entered into a clinical supply agreement with Apollomics under which we will manufacture and supply uproleselan product to Apollomics at agreed upon prices. Apollomics has the option to begin manufacture after appropriate material transfer requirements are met. During the year ended December 31, 2021, we recognized $1.1 million in revenue from the sale of clinical supplies to Apollomics under the clinical supply agreement. There were no sales of clinical supplies to Apollomics during the quarters ended March 31, 2024 or 2023.

Critical Accounting Policies and Significant Judgments and Estimates

​

Our management’s discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance with generally accepted accounting principles in the United States, or GAAP. The preparation of these financial statements requires us to make estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities as of the dates of the balance sheets and the reported amounts of revenue and expenses during the reporting periods. In accordance with GAAP, we base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances at the time such estimates are made. Actual results may materially differ from our estimates and judgments under different assumptions or conditions. We periodically review our estimates in light of changes in circumstances, facts and experience. The effects of material revisions in estimates are reflected in our financial statements prospectively from the date of the change in estimate.

​

We define our critical accounting policies as those accounting principles generally accepted in the United States that require us to make subjective estimates and judgments about matters that are uncertain and are likely to have a material impact on our financial condition and results of operations, as well as the specific manner in which we apply those principles. For a description of our critical accounting policies and estimates, please see the disclosures in Part II, Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2023. There have not been any material changes to our critical accounting policies and estimates since December 31, 2023.

​

Components of Operating Results

Revenue

To date, we have not generated any revenue from the sale of our drug candidates and do not expect to generate any revenue from the sale of drugs in the near future. Substantially all of our historical revenue consisted of upfront and milestone payments under license and collaboration agreements.

Table of Contents

Research and Development

Research and development expenses consist of expenses incurred in performing research and development activities, including compensation and benefits for full-time research and development employees, facilities expenses, overhead expenses, cost of laboratory supplies, clinical trial and related clinical manufacturing expenses, fees paid to CROs and other consultants and other outside expenses. Other preclinical research and platform programs include activities related to exploratory efforts, target validation, lead optimization for our earlier programs and our proprietary glycomimetics platform. Our research and development expenses have related primarily to the development of uproleselan and our other drug candidates.

We do not currently utilize a formal time allocation system to capture expenses on a project-by-project basis because we are organized and record expense by functional department and our employees may allocate time to more than one development project. Accordingly, we only allocate a portion of our research and development expenses by functional area and by drug candidate.

​

Research and development costs are expensed as incurred. Non-refundable advance payments for goods or services to be received in the future for use in research and development activities are deferred and capitalized. The capitalized amounts are expensed as the related goods are delivered or the services are performed.

​

Research and development activities are central to our business model. Drug candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later stage clinical trials. We expect our research and development expenses to increase over the next several years as we seek to progress uproleselan, GMI-1687 and our other drug candidates into and through clinical development. However, it is difficult to determine with certainty the duration and completion costs of our current or future preclinical studies and clinical trials of our drug candidates, or if, when or to what extent we will generate revenues from the commercialization and sale of any of our drug candidates that obtain regulatory approval. We may never succeed in achieving regulatory approval for any of our drug candidates.

The duration, costs and timing of clinical trials and development of our drug candidates will depend on a variety of factors that include:

| ● | per patient trial costs;

| ● | the number of patients that participate in the trials;

| ● | the number of sites included in the trials;

| ● | the countries in which the trial is conducted;

| ● | the length of time required to enroll eligible patients;

| ● | the number of doses that patients receive;

| ● | the drop-out or discontinuation rates of patients;

| ● | potential additional safety monitoring or other studies requested by regulatory agencies;

| ● | the duration of patient follow-up; and

| ● | the safety and efficacy profile of the drug candidate.

In addition, the probability of success for each drug candidate will depend on numerous factors, including competition, manufacturing capability and commercial viability. We will determine which programs to pursue and how much to fund each program in response to the scientific and clinical success of each drug candidate, as well as an assessment of each drug candidate’s commercial potential.

​

Our research and development expense for the three months ended March 31, 2024 increased by $606,000 compared to the same period ended March 31, 2023 primarily due an increase in uproleselan manufacturing and

formulation costs for commercial product, offset in part by decreases in drug discovery expenses, including personnel-related costs and costs for general laboratory supplies.

General and Administrative Expense

​

The following table summarizes the components of our general and administrative expense for the three months ended March 31, 2024 and 2023:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​

​

General and administrative expenses decreased by $432,000 for the three months ended March 31, 2024 as compared to the same period in 2023. The decrease was primarily due to lower personnel-related expenses, as the quarter ended March 31, 2023 included a one-time severance accrual, and a decrease in professional fees related to timing of commercial readiness expenses for uproleselan in the first quarter of 2024 as compared to 2023. These decreases were offset by higher stock-based compensation expenses in the first quarter of 2024 as compared to 2023 due to a higher fair market value for shares issued in 2024 as compared to 2023.

​

Interest Income

​

During the three months ended March 31, 2024 interest income decreased by $204,000 due to lower invested cash and cash equivalent balances in the first quarter of 2024 as compared to 2023.

​

Liquidity and Capital Resources

​

Sources of Liquidity

We have historically financed our operations primarily through public offerings and private placements of our capital stock, including sales agreements with Cowen, and upfront and milestone payments from our license and collaboration agreements. As of March 31, 2024, we had $31.3 million in cash and cash equivalents.

In March 2022, we filed a shelf registration statement with the SEC, which was declared effective on April 22, 2022. In April 2022, we entered into an at-the-market sales agreement, or the 2022 Sales Agreement, with Cowen. Under the 2022 Sales Agreement, we may sell up to $100.0 million in shares of our common stock. During the year ended December 31, 2022, we sold 1,953,854 shares of common stock under the 2022 Sales Agreement at a weighted average price of $2.22 per share, for aggregate net proceeds of $4.2 million, after deducting commissions and offering expenses. During the year ended December 31, 2023, we sold 9,822,930 shares of common stock under the 2022 Sales Agreement at a weighted average price of $3.01 per share, for aggregate net proceeds of $28.7 million, after deducting commissions and offering expenses. There were no shares sold in the quarter ended March 31, 2024. As of March 31, 2024, $66.0 million remained available to be sold under the 2022 Sales Agreement.

​

We entered into a collaboration and license agreement with Apollomics in 2020 and are potentially eligible to earn milestone payments and royalties under that agreement. However, our ability to earn milestone payments and potential royalty payments and their timing will be dependent upon the outcome of Apollomics’ activities and is therefore uncertain at this time.

​

Funding Requirements

Our primary uses of capital are, and we expect will continue to be, compensation and related expenses, third-party clinical research and development services, clinical costs, manufacturing costs, legal and other regulatory expenses and general overhead costs.

​

As of March 31, 2024, our significant contractual obligations consisted solely of rent obligations under a non-cancelable lease, as amended, for our current office space in Rockville, Maryland, which has a term through January 2025. Total remaining obligations under this lease as of March 31, 2024 were $631,000. In April 2024, we entered into a purchase commitment with a manufacturing vendor in the amount of $3,768,000 for 120 kg of raw materials to support the next commercial manufacturing campaign. Under the agreement, we paid a non-refundable advance of $1,130,400 to the vendor with the remainder of the purchase order due, if at all, at the completion of the produced quantity. In January 2024, we entered into a project agreement for the manufacture and supply of injectable uproleselan from active pharmaceutical ingredient for commercial sale should we receive marketing approval from the FDA. The initial term of the agreement is through year end 2026 with automatic 3-year renewal periods unless otherwise terminated by either party. We have no other fixed long-term obligations and we do not have significant capital expenditure requirements.

​

We have also entered into various agreements for services with third-party vendors, including agreements to conduct clinical trials, to manufacture products, and for consulting and other contracted services. These agreements include cancellable terms and we accrue the costs of these agreements based on estimates of work completed to date.

​

The successful development of any of our drug candidates is highly uncertain. As such, at this time, we cannot reasonably estimate or know the nature, timing and costs of the efforts that will be necessary to complete the remainder of the development of uproleselan or our other drug candidates. We are also unable to predict when, if ever, material net cash inflows will commence from uproleselan or our other drug candidates. This is due to the numerous risks and uncertainties associated with developing drugs, including the uncertainty of:

​

| ● | successful enrollment in, and completion of, clinical trials;

​

| ● | receipt of marketing approvals from applicable regulatory authorities;

​

| ● | establishing commercial manufacturing capabilities or making arrangements with third-party manufacturers;

​

| ● | obtaining and maintaining patent and trade secret protection and regulatory exclusivity for drug candidates;

​

| ● | launching commercial sales of drugs, if and when approved, whether alone or in collaboration with others; and

​

| ● | obtaining and maintaining healthcare coverage and adequate reimbursement.

​

A change in the outcome of any of these variables with respect to the development of any of our drug candidates would significantly change the costs and timing associated with the development of that drug candidate. Because our drug candidates are in various stages of clinical and preclinical development and the outcome of these efforts is uncertain, we cannot estimate the actual amounts necessary to successfully complete the development and commercialization of our drug candidates or whether, or when, we may achieve profitability. Until such time, if ever, as we can generate substantial product revenues, we expect to finance our cash needs through a combination of equity or debt financings and collaboration arrangements, including our existing license agreement with Apollomics. Except for amounts that we may sell under our 2022 Sales Agreement with Cowen, and Apollomics’ conditional obligations to make milestone and royalty payments to us under our license agreement, we do not have any committed external source of liquidity.

​

To the extent that we raise additional capital through the future sale of equity or debt, the ownership interest of our stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our existing common stockholders. If we raise additional funds through the issuance of convertible debt securities, these securities could contain covenants that would restrict our operations.

24

Table of Contents

We may require additional capital beyond our currently anticipated amounts. Additional capital may not be available on reasonable terms, or at all. If we raise additional funds through collaboration arrangements in the future, we may have to relinquish valuable rights to our drug candidates or grant licenses on terms that may not be favorable to us. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our drug development or future commercialization efforts or grant rights to develop and market drug candidates that we would otherwise prefer to develop and market ourselves.

​

Going Concern

The accompanying financial statements included in this report have been prepared assuming that we will continue as a going concern within one year after the date that the financial statements are issued. During 2023, we incurred a net loss of $36.9 million and had net cash flows used in operating activities of $34.9 million. At March 31, 2024, we had $31.3 million in cash and cash equivalents and had no committed source of additional funding from either debt or equity financings, although we may, in our discretion, sell equity securities under the 2022 Sales Agreement described above, subject to certain conditions and limitations. Management believes that given our current cash position and forecasted negative cash flows from operating activities over the next twelve months as we continue our product development activities, there is substantial doubt about our ability to continue as a going concern beyond the date that is one year from the date that the financial statements included in this report are issued, without obtaining additional financing or entering into another form of non-equity or debt arrangement.

​

Outlook

Based on our research and development plans and our timing expectations related to the progress of our programs, we expect that our existing cash and cash equivalents will enable us to fund our operating expenses and capital expenditure requirements through the fourth quarter of 2024. We have based this estimate on assumptions that may prove to be wrong, and we could use our capital resources sooner than we expect. Additionally, the process of testing drug candidates in clinical trials is costly, and the timing of progress in these trials is uncertain. Further, considering the results of the pivotal Phase 3 clinical trial of uproleselan in R/R AML patients, we plan to reduce expenses in the upcoming months in order to preserve capital while we evaluate our operating plans.

​

Cash Flows

​

The following is a summary of our cash flows for the three months ended March 31, 2024 and 2023:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | Three Months Ended March 31, | ​
(in thousands) | ​ | 2024 | ​ | 2023 |
Net cash provided by (used in): |  | ​ | ​ |  | ​ | ​ | ​

Financing activities | ​ |  | 5 | ​ |  | 28,741 | ​
Net change in cash and cash equivalents | ​ | $ | (10,511) | ​ | $ | 17,132 | ​

​

Operating Activities

​

Net cash used in operating activities for the three months ended March 31, 2024 and 2023 was primarily the result of pre-commercialization efforts and clinical and manufacturing costs associated with our uproleselan clinical development programs. These cash expenses were offset by non-cash expenses for stock-based compensation, lease expense and depreciation.

​

Investing Activities

​

Net cash used in investing activities for the three months ended March 31, 2024 and 2023 was for computer and laboratory equipment and was not material.

​

ITEM 3. | QUANTITATIVE AND QUALITATIV E DISCLOSURES ABOUT MARKET RISK

We are a smaller reporting company as defined by Item 10 of Regulation S-K and are not required to provide the information otherwise required under this item.

​

ITEM 4. CONTROLS AND PROCEDURES

​

(a) Evaluation of Disclosure Controls and Procedures

​

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, refers to controls and procedures 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 such information is accumulated and communicated to a company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure.

​

In designing and evaluating our disclosure controls and procedures, management recognizes that disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Additionally, in designing disclosure controls and procedures, our management necessarily was required to apply its judgment in evaluating the cost-benefit relationship of possible disclosure controls and procedures. The design of any system of controls also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions; over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate.

​

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2024, the end of the period covered by this Quarterly Report on Form 10-Q. Based upon such evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that our disclosure controls and procedures were effective as of such date at the reasonable assurance level.

​

(b) Changes in Internal Controls Over Financial Reporting

​

There have not been any changes in our internal controls over financial reporting during our fiscal quarter ended March 31, 2024 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

​

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDING S

​

From time to time, we are subject to litigation and claims arising in the ordinary course of business. We are not currently a party to any material legal proceedings and we are not aware of any pending or threatened legal proceeding against us that we believe could have a material adverse effect on our business, operating results, cash flows or financial condition.

​

Table of Contents

ITEM 1A. RISK FACTOR S

​

Our business is subject to risks and events that, if they occur, could adversely affect our financial condition and results of operations and the trading price of our securities. Except as set forth below our risk factors as of the date of this quarterly report on Form 10-Q have not changed materially from those described in “Part I, Item 1A. Risk Factors” of our Annual Report on Form 10-K for the fiscal year ended December 31, 2023, filed with the SEC on March 27, 2024.

​

We will need substantial additional funding to pursue our business objectives. If we are unable to raise capital when needed, we may not be able to continue as a going concern and could be forced to delay, reduce or eliminate our drug development programs or potential commercialization efforts.

We believe that our existing cash and cash equivalents will enable us to fund our operating expenses and capital expenditure requirements through the fourth quarter of 2024. However, we will need to obtain substantial additional funding in connection with our continuing operations. In May 2024, we announced results of our pivotal Phase 3 clinical trial of uproleselan in Relapsed/Refractory (R/R) Acute Myeloid Leukemia (AML). The study of uproleselan combined with chemotherapy did not meet its primary endpoint of overall survival in the intent to treat population. Considering these results, our future capital requirements will depend on many factors, including:

| ● | the scope, progress, results and costs of preclinical development, laboratory testing and clinical trials for our drug candidates;

| ● | the number and development requirements of other drug candidates that we may pursue;

| ● | the costs, timing and outcome of regulatory review of our drug candidates;

| ● | the costs and timing of future commercialization activities, including product manufacturing, marketing, sales and distribution, for any of our drug candidates for which we receive marketing approval;

| ● | the revenue, if any, received from commercial sales of our drug candidates for which we receive marketing approval;

| ● | the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending any intellectual property-related claims; and

| ● | the extent to which we acquire or in-license other drug candidates and technologies.

Our management must periodically evaluate whether there are conditions or events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern. Based on our current cash position, our ongoing significant operating losses, the results from our pivotal Phase 3 clinical trial of uproleselan in R/R AML and the fact that we do not have any committed sources of revenue or cash flows other than potential payments from our license and collaboration agreements, management believes that, given our current cash position, there is substantial doubt about our ability to continue as a going concern beyond the fourth quarter of 2024.

Identifying potential drug candidates and conducting preclinical testing and clinical trials is a time-consuming, expensive and uncertain process that takes years to complete, and we or any current or future collaborators may never generate the necessary data or results required to obtain regulatory approval and achieve product sales. In addition, our drug candidates, if approved, may not achieve commercial success. Accordingly, our ability to fund our operations is dependent upon management’s plans, which include raising additional capital in the near term primarily through a combination of equity and debt financings, collaborations and strategic alliances. There can be no assurances that new financings or other transactions will be available to us on commercially acceptable terms, or at all. Our ability to raise additional capital may also be adversely impacted by global economic conditions and disruptions to and volatility in the credit and financial markets in the United States and worldwide. If we are unable to raise capital to fund our operations when needed or on attractive terms, we could be forced to delay, reduce the scope of or eliminate our research and development programs or any future commercialization efforts, which would have a material adverse effect on our business, financial condition, results of operations and ability to operate as a going concern.

Table of Contents

We have only one drug candidate in a late-stage clinical trial. All of our other drug candidates are in earlier stages of clinical trials or in preclinical development. If we or our collaborators are unable to commercialize our drug candidates or experience significant delays in doing so, our business will be materially harmed.

Uproleselan is our only drug candidate that is in a Phase 2 or Phase 3 clinical trial. Our other drug candidates are in earlier stages of clinical trials or in preclinical development. In May 2024, we announced results of our pivotal Phase 3 clinical trial of uproleselan in R/R AML. The study of uproleselan combined with chemotherapy did not meet its primary endpoint of overall survival in the intent to treat population. We have not completed the development of any drug candidates, we currently generate no revenue from the sale of any drugs and we may never be able to develop a marketable drug. As a company, we have no experience in submitting and obtaining FDA approval for an NDA and, even if our other uproleselan trials are successful, FDA may disagree with our interpretation of the data and our NDA may receive either a refusal to file letter or complete response letter. We have invested substantially all of our efforts and financial resources in the development of our glycomimetics platform, the identification of potential drug candidates

using that platform and the development of our drug candidates. Our ability to generate revenue from our other drug candidates, which we do not expect to occur for many years, if ever, will depend heavily on their successful development and eventual commercialization. The success of those drug candidates will depend on several factors, including:

| ● | successful completion of preclinical studies and clinical trials;

| ● | receipt of marketing approvals from applicable regulatory authorities;

| ● | obtaining and maintaining patent and trade secret protection and regulatory exclusivity for our drug candidates;

| ● | making arrangements with third-party manufacturers for, or establishing, commercial manufacturing capabilities;

| ● | launching commercial sales of the drugs, if and when approved, whether alone or in collaboration with others;

| ● | acceptance of the drugs, if and when approved, by patients, the medical community and third-party payors;

| ● | effectively competing with other therapies;

| ● | obtaining and maintaining healthcare coverage and adequate reimbursement;

| ● | protecting our rights in our intellectual property portfolio; and

| ● | maintaining a continued acceptable safety profile of the drugs following approval.

If we do not achieve one or more of these factors in a timely manner or at all, we could experience significant delays or an inability to successfully commercialize our drug candidates, which would materially harm our business.

Clinical drug development involves a lengthy and expensive process, with an uncertain outcome. We may incur additional costs or experience delays in completing, or ultimately be unable to complete, the development and commercialization of our drug candidates.

The risk of failure of our drug candidates is high. It is impossible to predict when or if any of our drug candidates will prove safe or effective in humans or will receive regulatory approval. Before obtaining marketing approval from regulatory authorities for the sale of any drug candidate, we or a collaborator must complete preclinical development and then conduct extensive clinical trials to demonstrate the safety and efficacy of the drug candidate in humans. Clinical testing is expensive, difficult to design and implement, can take many years to complete and is uncertain as to outcome. A failure of one or more clinical trials can occur at any stage of development. For example, in May 2024, we announced results of our pivotal Phase 3 clinical trial of uproleselan in R/R AML. Even though we observed favorable results in earlier trials of uproleselan, uproleselan combined with chemotherapy did not meet the primary endpoint of overall survival in the intent to treat population in our Phase 3 trial. In general, the outcome of preclinical testing and early clinical trials may not be predictive of the success of later clinical trials, and interim results of a clinical trial do not necessarily predict final results. In addition, changes in patient treatment options over time may make the relevance of historical control data for a given indication less relevant to the drug candidate being studied, which could impact the

28

Table of Contents

success of the trial or, even if successful, the desirability of a successful drug candidate versus other available treatment options. Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses, and many companies that have believed their drug candidates performed satisfactorily in preclinical studies and clinical trials have nonetheless failed to obtain marketing approval of their drugs.

We or our current or future collaborators may experience numerous unforeseen events during, or as a result of, clinical trials that could delay or prevent our or their ability to receive marketing approval or commercialize our drug candidates, including:

| ● | regulators or institutional review boards may not authorize us or our investigators to commence a clinical trial or conduct a clinical trial at a prospective trial site;

| ● | we may experience delays in reaching, or fail to reach, agreement on acceptable clinical trial contracts or clinical trial protocols with prospective trial sites;

| ● | clinical trials of our drug candidates may produce negative or inconclusive results, including failure to demonstrate statistical significance, and we may decide, or regulators may require us, to conduct additional clinical trials or abandon drug development programs;

| ● | the number of patients required for clinical trials of our drug candidates may be larger than we anticipate, enrollment in these clinical trials may be slower than we anticipate or participants may drop out of these clinical trials at a higher rate than we anticipate;

| ● | our third-party contractors may fail to comply with regulatory requirements or meet their contractual obligations to us in a timely manner, or at all;

| ● | regulators or institutional review boards may require that we or our investigators suspend or terminate clinical research for various reasons, including noncompliance with regulatory requirements or a finding that the participants are being exposed to unacceptable health risks;

| ● | the cost of clinical trials of our drug candidates may be greater than we anticipate;

| ● | the supply or quality of our drug candidates or other materials necessary to conduct clinical trials of our drug candidates may be insufficient or inadequate; and

| ● | our drug candidates may have undesirable side effects or other unexpected characteristics, causing us or our investigators, regulators or institutional review boards to suspend or terminate the trials.

If we are required to conduct additional clinical trials or other testing of our drug candidates beyond those that we currently contemplate, if we are unable to successfully complete clinical trials of our drug candidates or other testing, if the results of these clinical trials or tests are not positive or are only modestly positive or if there are safety concerns, we may:

| ● | be delayed in obtaining marketing approval for our drug candidates;

| ● | not obtain marketing approval at all;

| ● | obtain approval for indications or patient populations that are not as broad as intended or desired;

| ● | obtain approval with labeling that includes significant use or distribution restrictions or safety warnings;

| ● | be subject to additional post-marketing testing requirements; or

| ● | have the drug removed from the market after obtaining marketing approval.

Our drug development costs will also increase if we experience delays in testing or marketing approvals. We do not know whether any of our preclinical studies or 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 may have the exclusive right to commercialize our drug candidates or allow our competitors to bring drugs to market before we do, and thereby impair our ability to successfully commercialize our drug candidates.
