SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS AND INDUSTRY DATA

This Quarterly Report on Form 10-Q (this “Quarterly Report”) contains forward-looking statements which reflect our current views with respect to, among other things, our operations and financial performance. Such statements are based upon our current plans, estimates and expectations that are subject to various risks and uncertainties that could cause actual results to differ materially from such statements. The inclusion of forward-looking statements should not be regarded as a representation that such plans, estimates and expectations will be achieved. Words such as “anticipate,” “expect,” “project,” “intend,” “believe,” “may,” “will,” “should,” “plan,” “could,” “continue,” “target,” “contemplate,” “estimate,” “forecast,” “guidance,” “predict,” “possible,” “potential,” “pursue,” “likely,” and words and terms of similar substance used in connection with any discussion of future plans, actions or events identify forward-looking statements. All statements, other than historical facts, including statements regarding estimations of projected cash runway; our future product development plans; the potential, safety, efficacy, and regulatory and clinical progress of our product candidates, including the anticipated timing for initiation of clinical trials and release of clinical trial data and the expectations surrounding potential regulatory submissions, approvals and timing thereof; and any assumptions underlying any of the foregoing, are forward-looking statements. Important factors that could cause actual results to differ materially from our plans, estimates or expectations could include, but are not limited to: (i) our ability and plan to develop and commercialize DKN-01, FL-301 and our preclinical programs; (ii) status, timing and results of our preclinical studies and clinical trials; (iii) the potential benefits of DKN-01, FL-301 and our preclinical programs; (iv) the timing of our development programs and seeking regulatory approval of DKN-01, FL-301 and our preclinical programs; (v) our ability to obtain and maintain regulatory approval; (vi) our estimates of expenses and future revenues and profitability; (vii) our estimates regarding our capital requirements and our needs for additional financing; (viii) our estimates of the size of the potential markets for DKN-01, FL-301 and our preclinical programs; (ix) the benefits to be derived from any collaborations, license agreements, or other acquisition efforts, including the ongoing collaborations with BeiGene, NovaRock and Adimab; (x) sources of revenues and anticipated revenues, including contributions from any collaborations or license agreements for the development and commercialization of products; (xi) the rate and degree of market acceptance of DKN-01, FL-301 or our preclinical products; (xii) the success of other competing therapies that may become available; (xiii) the manufacturing capacity for our products; (xiv) our intellectual property position; (xv) our ability to maintain and protect our intellectual property rights; (xvi) our results of operations, financial condition, liquidity, prospects, and growth and strategies; (xvii) the industry in which we operate; (xviii) the trends that may affect the industry or us; (xix) the effect of inflation, currency rate and interest rate fluctuations, as well as fluctuations in the market price of our traded securities and (xx) that the initiation, conduct, and completion of clinical trials, laboratory operations, manufacturing campaigns, and other studies may be delayed, adversely affected, or impacted by global conflict or supply chain related issues.

By their nature, forward-looking statements involve risks and uncertainties because they relate to events, competitive dynamics and industry change, and depend on economic circumstances that may or may not occur in the future or may occur on longer or shorter timelines than anticipated. Although we believe that we have a reasonable basis for each forward-looking statement contained in this Quarterly Report, we caution you that forward-looking statements are not guarantees of future performance and that our actual results of operations, financial condition and liquidity, and the development of the industry in which we operate may differ materially from the forward-looking statements contained in this Quarterly Report. In addition, even if our results of operations, financial condition and liquidity, and events in the industry in which we operate are consistent with the forward-looking statements contained in this Quarterly Report, they may not be predictive of results or developments in future periods. You should carefully read this Quarterly Report and any documents that we have filed as exhibits to this Quarterly Report completely.

Table of Contents

You should refer to Part II, Item 1A, Risk Factors in this Quarterly Report and Part I, Item 1A, Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2023, as filed with the Securities and Exchange Commission on March 18, 2024, for a discussion of important factors that may cause our actual results to differ materially from those expressed or implied by our forward-looking statements. As a result of these factors, we cannot assure you that the forward-looking statements in this Quarterly Report will prove to be accurate. Furthermore, if our forward-looking statements prove to be inaccurate, the inaccuracy may be material. In light of the significant uncertainties in these forward-looking statements, you should not regard any such statement as a representation or warranty by us or any other person that we will achieve our objectives and plans in any specified timeframe, or at all. Any forward-looking statement that we make in this Quarterly Report speaks only as of the date of such statement, and, except to the extent required by applicable law, we undertake no obligation to update such statements to reflect events or circumstances after the date of this Quarterly Report or to reflect the occurrence of unanticipated events. You should, therefore, not rely on these forward-looking statements as representing our views as of any date subsequent to the date of this Quarterly Report. Comparisons of results for current and any prior periods are not intended to express any future trends or indications of future performance, unless expressed as such, and should only be viewed as historical data.

DKN-01 and FL-301 are investigational drugs undergoing clinical development and have not been approved by the U.S. Food and Drug Administration (the “FDA”), nor have they been submitted to the FDA for approval. DKN-01 and FL-301 have not been, and may never be, approved by any regulatory agency or marketed anywhere in the world. Statements contained in this Quarterly Report should not be deemed to be promotional.

1. Nature of Business, Basis of Presentation and Liquidity

Nature of Business

Leap Therapeutics, Inc. was incorporated in the state of Delaware on January 3, 2011. During 2015, HealthCare Pharmaceuticals Pty Ltd. was formed and is a wholly owned subsidiary of the Company.

On December 10, 2015, the Company entered into a merger agreement with GITR Inc. (“GITR”), an entity under common control, whereby a wholly owned subsidiary was merged with GITR and the surviving name of the wholly owned subsidiary was GITR Inc.

On August 29, 2016, the Company entered into a merger agreement with Macrocure Ltd. (“Macrocure”), a publicly held, clinical stage biotechnology company based in Petach Tikva, Israel. In connection with the merger, the Company applied to be listed on the Nasdaq Global Market. Nasdaq approved the listing, and trading in the Company’s common stock commenced on January 24, 2017, under the trading symbol “LPTX.” On February 1, 2017, Macrocure’s name was changed to Leap Therapeutics Ltd. In 2020, Leap Therapeutics Ltd. was dissolved.

On December 15, 2021, Leap Securities Corp. was formed and is a wholly owned subsidiary of the Company.

On January 17, 2023, the Company entered into a merger agreement with Flame Biosciences, Inc., a privately held, biotechnology corporation (“Flame”), whereby Flame became a wholly owned subsidiary of the Company under the name Flame Biosciences, LLC.

The Company is a biopharmaceutical company developing novel biomarker-targeted antibody therapies designed to treat patients with cancer by inhibiting fundamental tumor-promoting pathways, targeting cancer-specific cell surface molecules, and harnessing the immune system to attack cancer cells. The Company’s strategy is to identify, acquire, and develop molecules that translate into therapeutics that generate durable clinical benefit and enhanced patient outcomes. The Company’s lead clinical stage program is DKN-01, a monoclonal antibody that inhibits Dickkopf-related protein 1, or DKK1. The Company is currently studying DKN-01 in multiple ongoing clinical trials in patients with esophagogastric cancer, gynecologic cancers, or colorectal cancer. Its second clinical stage program is FL-301, a monoclonal antibody that targets cells that express Claudin18.2 on their cell surface. The Company also has two preclinical antibody programs, FL-302 and FL-501.

In January 2020, the Company entered into an Option and License Agreement with BeiGene, Ltd., or BeiGene, which granted BeiGene an option to obtain an exclusive license from the Company that would grant to BeiGene the right to develop and commercialize DKN-01 in Asia (excluding Japan), Australia, and New Zealand. In March 2023, BeiGene notified the Company that it did not intend to exercise its option, and the agreement is continuing as a clinical collaboration.

The Company intends to apply its experience identifying and developing products to build a pipeline of programs relating to the practice of cancer medicine.

Basis of Presentation

The December 31, 2023 year-end condensed consolidated balance sheet data in the accompanying interim condensed consolidated financial statements was derived from audited consolidated financial statements. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. However, the Company believes that the disclosures are adequate to make the information presented not misleading. These condensed consolidated financial statements should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto for the year ended December 31, 2023, included in the Company’s Annual Report on Form 10-K filed with the SEC on March 18, 2024.

The accompanying interim condensed consolidated financial statements are unaudited and have been prepared on the same basis as the audited consolidated financial statements as of and for the year ended December 31, 2023. In the opinion of management, the accompanying condensed consolidated financial statements contain all adjustments which are necessary for the fair presentation of the Company’s financial position as of March 31, 2024, statements of operations and statements of comprehensive loss 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. Such adjustments are of a normal and recurring nature. The results of operations for the three months ended March 31, 2024 are not necessarily indicative of the results of operations that may be expected for the year ending December 31, 2024.

Reverse Stock Split

On June 21, 2023, the Company effected a one-for-ten reverse stock split of its issued and outstanding shares of common stock, which also adjusted the conversion ratio of its Series X Preferred Stock such that each share of Series X Preferred Stock became convertible into 100 shares of common stock. Accordingly, all share and per share amounts for all periods presented in the accompanying condensed consolidated financial statements and notes thereto have been adjusted retroactively, where applicable, to reflect this stock split. All fractional shares resulting from the reverse stock split were paid in cash.

Liquidity

Since inception, the Company has been engaged in organizational activities, including raising capital, and research and development activities. The Company does not yet have a product that has been approved by the FDA, has not generated any product sales revenues and has not yet achieved profitable operations, nor has it ever generated positive cash flows from operations. There is no assurance that profitable operations, if achieved, could be sustained on a continuing basis. Further, the Company’s future operations are dependent on the success of the Company’s efforts to raise additional capital, its research and commercialization efforts, regulatory approval, and, ultimately, the market acceptance of the Company’s products.

In accordance with Accounting Standards Codification (“ASC”) 205-40, Going Concern, the Company has evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the condensed consolidated financial statements are issued. As of March 31, 2024, the Company had cash and cash equivalents of $54,921. In April 2024, the Company completed a private placement (“April 2024 Private Placement”), resulting in net proceeds of approximately $37,200, net of underwriting discounts and commissions and estimated offering expenses payable by the Company. Additionally, the Company had an accumulated deficit of $413,402 at March 31, 2024, and during the three months ended March 31, 2024, the Company incurred a net loss of $13,820. The Company expects to continue to generate operating losses for the foreseeable future. The Company believes that its cash and cash equivalents of $54,921 as of March 31, 2024, together with the net proceeds of approximately $37,200 from the April 2024 Private Placement, will be sufficient to fund its operating expenses for at least the next 12 months from issuance of these financial statements.

In addition, to support its future operations, the Company will likely seek additional funding through public or private equity financings or government programs and will seek funding or development program cost-sharing through collaboration agreements or licenses with larger pharmaceutical or biotechnology companies. If the Company does not obtain additional funding or development program cost-sharing, or exceeds its current spending forecasts or fails to receive the research and development tax incentive payment, the Company has the ability and would be forced to delay, reduce or eliminate certain clinical trials or research and development programs, reduce or eliminate discretionary operating expenses, and delay company and pipeline expansion, any of which could adversely affect its business prospects. The inability to obtain funding, as and when needed, could have a negative impact on the Company’s financial condition and ability to pursue its business strategies.

2. Summary of Significant Accounting Policies

Principles of Consolidation

The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions are eliminated upon consolidation.

Use of Estimates

The presentation of condensed consolidated 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 contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Research and development incentive income and receivable

The Company recognizes other income from Australian research and development incentives when there is reasonable assurance that the income will be received, the relevant expenditure has been incurred, and the consideration can be reliably measured. The research and development incentive is one of the key elements of the Australian government’s support for Australia’s innovation system and is supported by legislative law primarily in the form of the Australian Income Tax Assessment Act 1997, as long as eligibility criteria are met.

Management has assessed the Company’s research and development activities and expenditures to determine which activities and expenditures are likely to be eligible under the research and development incentive regime described above. At each period end, management estimates the refundable tax offset available to the Company based on available information at the time.

Under the program, a percentage of eligible research and development expenses incurred by the Company through its subsidiary in Australia are reimbursed. The percentage was 43.5% for the year ended December 31, 2023 and for the three months ended March 31, 2024.

The research and development incentive receivable represents an amount due in connection with the above program. The Company recorded a research and development incentive receivable of $983 and $771 as of March 31, 2024 and December 31, 2023, respectively, in the condensed consolidated balance sheets and other income from Australian research and development incentives of $246 and $272, respectively, for the three months ended March 31, 2024 and 2023.

The following table shows the change in the research and development incentive receivable from January 1, 2023 to March 31, 2024 (in thousands):


Balance at January 1, 2023	$	2,099
Cash received for 2022 eligible expenses		(2,333)
Australian research and development incentive income, net		1,101
Foreign currency translation		(96)
Balance at December 31, 2023	$	771
Australian research and development incentive income, net		246
Foreign currency translation		(34)
Balance at March 31, 2024	$	983

Foreign Currency Translation

The financial statements of the Company’s Australian subsidiary are measured using the local currency as the functional currency. Assets and liabilities of this subsidiary are translated into U.S. dollars at an exchange rate as of the consolidated balance sheet date. Equity is translated at historical exchange rates. Revenues and expenses are translated into U.S. dollars at average rates of exchange in effect during the period. The resulting cumulative translation adjustments have been recorded as a separate component of stockholders’ equity. Realized and unrealized foreign currency transaction gains and losses are included in the results of operations.

Table of Contents

Concentration of Credit Risk

Financial instruments that potentially subject the Company to credit risk consist principally of cash and cash equivalents. All cash and cash equivalents are held in United States or Australian financial institutions and money market funds. At times, the Company may maintain cash balances in excess of the federally insured amount of $250 per depositor, per insured bank, for each account ownership category. Although the Company currently believes that the financial institutions with whom it does business will be able to fulfill their commitments to the Company, there is no assurance that those institutions will be able to continue to do so. The Company has not experienced any credit losses associated with its balances in such accounts for the year ended December 31, 2023 or for the three months ended March 31, 2024.

Deposits

As of March 31, 2024 and December 31, 2023, there were $917 and $966, respectively, of deposits made by the Company with certain service providers that are to be applied to future payments due under the service agreements or returned to the Company if not utilized, which were recorded in the condensed consolidated balance sheets.

Warrants

The Company will recognize on a prospective basis the value of the effect of the down round feature in the warrants to purchase shares of common stock that were issued in a private placement in November 2017 (the “2017 Warrants”) and in the warrants that were issued in a private placement in March 2020 (the “March 2020 Coverage Warrants”) when it is triggered (i.e., when the exercise price is adjusted downward). This value is measured as the difference between (1) the financial instrument’s fair value (without the down round feature) using the pre-trigger exercise price and (2) the financial instrument’s fair value (with the down round feature) using the reduced exercise price. The value of the effect of the down round feature will be treated as a dividend and a reduction to income available to common stockholders in the basic earnings per share (“EPS”) calculation.

The Company initially classified the warrants that were exercisable for shares for Series X Non-Voting Convertible Preferred Stock (the “January 2023 Series X Preferred Stock Warrants”) as a liability on its condensed consolidated balance sheet on January 17, 2023 and subsequently remeasured the warrant liability to fair value at each reporting date until the conversion of Series X Non-Voting Convertible Preferred Stock (the “Series X Preferred Stock”) into common stock, which occurred on June 21, 2023. Changes in the fair value of the warrant liability were recognized as gains (losses) in the Company’s condensed consolidated statement of operations.

In June 2023, in connection with obtaining Stockholder Approval to convert shares of Series X Preferred Stock into shares of common stock (“Stockholder Approval”), the January 2023 Series X Preferred Stock Warrants were reclassified from liability to equity.

Fair Value of Financial Instruments

Certain assets and liabilities are carried at fair value under GAAP. 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. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. Financial assets and liabilities carried at fair value are to be classified and disclosed in one of the following three levels of the fair value hierarchy, of which the first two are considered observable and the last is considered unobservable:

●

Level 1—Quoted prices in active markets for identical assets or liabilities.

●

Level 2—Observable inputs (other than Level 1 quoted prices), such as quoted prices in active markets for similar assets or liabilities, quoted prices in markets that are not active for identical or similar assets or liabilities, or other inputs that are observable or can be corroborated by observable market data.

●

Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to determining the fair value of the assets or liabilities, including pricing models, discounted cash flow methodologies and similar techniques.

Table of Contents

A summary of the assets carried at fair value in accordance with the hierarchy defined above is as follows (in thousands):


	Total		Level 1		Level 2		Level 3
March 31, 2024
Assets:
Cash equivalents	$	30,535	$	30,535	$	—	$	—

Assets:
Cash equivalents	$	39,065	$	39,065	$	—	$	—
Total assets	$	39,065	$	39,065	$	—	$	—

Cash equivalents of $30,535 and $39,065 as of March 31, 2024 and December 31, 2023, respectively, consisted of overnight investments and money market funds which are classified within Level 1 of the fair value hierarchy because they are valued using quoted market prices in active markets.

The carrying values of the research and development incentive receivable, accounts payable and accrued liabilities approximate their fair value due to the short-term nature of these assets and liabilities.

Leases

The Company accounts for leases in accordance with Accounting Standards Codification, or ASC, Topic 842, Leases.

At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the unique facts and circumstances present. Most 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 sheet leases with terms of one year or less. Operating lease liabilities and their corresponding right-of-use assets are recorded based on the present value of lease payments over the expected remaining lease term. The Company has determined that the rate implicit in the lease is not determinable and the Company does not have borrowings with similar terms and collateral. Therefore, the Company considered a variety of factors, including observable debt yields from comparable companies and the volatility in the debt market for securities with similar terms, in determining that 8% was reasonable to use as the incremental borrowing rate for purposes of the calculation of lease liabilities.

In accordance with the guidance in Topic 842, components of a lease should be split into three categories: lease components (e.g. land, building, etc.), non-lease components (e.g. common area maintenance, maintenance, consumables, etc.), and non-components (e.g. property taxes, insurance, etc.). Then the fixed and in-substance fixed contract consideration (including any related to non-components) must be allocated based on fair values to the lease components and non-lease components.

Although separation of lease and non-lease components is required, certain practical expedients are available. Entities may elect the practical expedient to not separate lease and non-lease components. Rather, they would account for each lease component and the related non-lease component together as a single component. The Company has elected to account for the lease and non-lease components of each of its operating leases as a single lease component and allocate all of the contract consideration to the lease component only. The lease component results in an operating right-of-use asset being recorded on the consolidated balance sheets and amortized such that lease expense is recorded on a straight line basis over the term of the lease.

Net Loss per Share

Basic net loss per share is computed using the weighted average number of common shares outstanding during the period. Diluted net loss per share is computed using the weighted average number of common shares outstanding during the period and, if dilutive, the weighted average number of potential shares of common stock, including the assumed exercise of stock options and warrants.

Subsequent Events

The Company considers events or transactions that occur after the balance sheet date but prior to the issuance of the financial statements to provide additional evidence for certain estimates or to identify matters that require additional disclosure. Subsequent events have been evaluated as required.

3. Acquisition of Flame Biosciences

Merger

On January 17, 2023 (the “Effective Date”), Leap acquired 100% of the outstanding equity of Flame, in accordance with the terms of the Agreement and Plan of Merger, dated as of the Effective Date (the “Merger Agreement”), by and among Leap, Fire Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Leap (“First Merger Sub”), Flame Biosciences LLC, a Delaware limited liability company and wholly owned subsidiary of Leap (“Second Merger Sub”), Flame, and the Stockholder Representative named therein. Pursuant to the Merger Agreement, First Merger Sub merged with and into Flame, and Flame was the surviving corporation of such merger and became a wholly owned subsidiary of Leap (the “First Merger”). Immediately following the First Merger, Flame merged with and into Second Merger Sub, and Second Merger Sub was the surviving entity of such merger (together with the First Merger, the “Merger”).

Pursuant to the Merger, Leap agreed to issue to the stockholders of Flame (the “Flame Stockholders”) 1,972,901 shares of common stock, and 136,248 shares of Series X Preferred Stock, which was a newly designated series of preferred stock that was intended to have economic rights equivalent to the common stock, but with limited voting rights, and issued to the warrant holders of Flame (the “Flame Warrant Holders”) the right to acquire 6,530 shares of common stock (the “January 2023 Common Stock Warrants”) and 443 shares of Series X Preferred Stock (the “January 2023 Series X Preferred Stock Warrants”). Each share of Series X Preferred Stock converted into 100 shares of common stock during the three months ended June 30, 2023, as a result of the one-for-ten reverse stock split approved by the stockholders and effected by the Board of Directors. Under the terms of the Merger Agreement, Leap held back approximately 15,604 Series X Preferred shares (the “Holdback Shares”), which converted into 1,560,400 shares of common stock out of the aggregate number of shares that the Flame Stockholders otherwise would be entitled to receive pursuant to the Merger so that Leap can have recourse to the Holdback Shares for purposes of satisfying certain claims for indemnification that Leap may have against the Flame Stockholders in connection with the Merger. In January 2024, Leap released the Holdback Shares to the Flame Shareholders.

On June 16, 2023, the Company obtained Stockholder Approval to convert the Series X Preferred Stock into shares of its common stock, which occurred on June 21, 2023.

Table of Contents

The Company accounted for the acquisition of Flame as an asset acquisition allocating the purchase price under GAAP of $79,016 to net assets acquired. Although there is a presumption under SEC Rule 11-01(d) (“11-01(d)”) that when a legal entity is acquired, it represents a business acquisition, the Company concluded that, in this case, the transaction did not represent the acquisition of a business. After considering the criteria set forth in 11-01(d), the Company concluded that the acquisition of Flame by the Company was an acquisition of assets and not an acquisition of a business in accordance with 11-01(d). Specifically, the Company concluded that 1) the entity did not generate revenue and 2) there was not sufficient continuity of Flame’s operations prior to and following the transaction, in that no facilities, employees, sales force, distribution system, customer base, trade names or production techniques remained with the entity after the acquisition.

Leap primarily acquired cash of $50,362, certain working capital items ($928) and a portfolio of clinical- and pre-clinical-stage intellectual property, in connection with the acquisition of Flame. The Company accounted for the acquisition of Flame by recording the cash and any other assets and liabilities of Flame on its condensed consolidated balance sheet at their historical carrying values, which approximates fair values. The remaining fair value of the consideration transferred was allocated to the in-process research and development (“IPR&D”) assets acquired. Certain transaction costs that were not deemed to meet the criteria of costs directly attributable to the issuance of securities were capitalized in accordance with ASC 805-50-30-1 and recognized as part of fair value of assets acquired. As the Company concluded that such IPR&D does not have an alternative future use, the relative fair value allocated to acquired IPR&D of $29,582 was expensed in research and development expenses within the Company’s condensed consolidated statement of operations during the three months ended March 31, 2023.

The following table summarizes the net assets acquired based on their estimated fair values as of January 17, 2023 (in thousands):


Acquired IPR&D	$	29,582
Cash and cash equivalents		50,362
Accounts payable and accrued liabilities		(928)
Total acquisition value	$	79,016

The fair value assigned to each component of the purchase consideration, including direct costs of the acquisition of $1,393, as of the Effective Date is set forth in the table below (in thousands, except share and per share amounts):


		Equivalent common
	Number of shares	shares	Fair Value
Leap common stock (par value $0.001 per share)	1,972,901	1,972,901	$	9,805
Leap Series X Preferred Stock (100:1)	136,248	13,624,800		67,715
Warrants on Leap common stock	6,530	6,530		13
Warrants on Leap Series X Preferred Stock (100:1)	443	44,300		90
Direct and incremental costs of the asset acquisition				1,393

Total		15,648,531	$	79,016

In addition, subject to and upon the terms and conditions set forth in the Merger Agreement, the Company may also (i) pay Contingent Merger Consideration (as defined in the Merger Agreement) that may become payable if, and only if, certain assets of Flame related to Flame’s FL-101 program and/or FL-103 program are sold after the consummation of the Merger pursuant to the FL-101/103 Disposition Agreement (as defined in the Merger Agreement), which Contingent Merger Consideration shall be 80% of the after-tax net proceeds of such sale, if any, and the payment thereof is subject to the terms and conditions set forth in the Merger Agreement and (ii) issue pursuant to the Merger additional shares of Series X Preferred Stock or common stock as a result of any applicable post-closing purchase price adjustment in the event that Flame’s actual Company Net Cash (as defined in the Merger Agreement) as of the Effective Date is determined to be greater than Flame’s estimated Company Net Cash as of the closing.

Sale of FL - 101/FL - 103 to AlmataBio, Inc.

On December 6, 2023 the Company sold certain IPR&D assets previously acquired from Flame related to Flame’s FL - 101/FL - 103 program, including permits, clinical trial material, clinical data, and related identified contracts, such as licensing, research, clinical trials, and various other agreements. The Company received total consideration in the form of a non - refundable closing date cash payment of $500.

Table of Contents

Pursuant to the terms of the asset purchase agreement, the Company is entitled to receive milestone payments of up to $70,000 upon achievement of certain regulatory approval and sales milestones specified in the asset purchase agreement.

The IPR&D assets sold related to Flame’s FL - 101/FL - 103 program did not meet the definition of a business and had a carrying value of $0 at the time of the sale. In addition, the Company estimated the likelihood of receiving any milestone payments to be remote. As such, management elected the most likely amount method to determine the transaction price of the sale, which included the non - refundable closing date cash payment of $500 and future milestone payments of $0. Therefore, the Company recognized a non - operating gain in other income for the difference between the amount of non - refundable consideration received of $500 and the carrying value of $0 during the year ended December 31, 2023. In the event of a change in circumstances, such that it becomes likely that the Company will receive milestone payments, the Company will recognize income for the change in transaction price in the period in which the transaction price changes.

In addition, during the year ended December 31, 2023, the Company incurred various qualified expenses, such as legal fees, consulting and general and administrative expenses in connection with the sale of Flame’s FL - 101 program. Such expenses exceeded the non - refundable consideration received of $500, and therefore, the Company was not obligated to pay Contingent Merger Consideration to the Flame Stockholders.

Series X Preferred Stock

Pursuant to the Merger, the Company agreed to issue 136,248 shares of Series X Preferred Stock to Flame Stockholders and January 2023 Series X Preferred Stock Warrants for 443 shares of Series X Preferred Stock to Flame Warrant Holders. The Company obtained Stockholder Approval during the three months ended June 30, 2023 to convert each issued share of Series X Preferred Stock and each share of Series X Preferred Stock issuable pursuant to the January 2023 Series X Preferred Stock Warrants into 100 shares of its common stock. The Series X Preferred Stock was converted to common stock on June 21, 2023.

January 2023 Common Stock Warrants and January 2023 Series X Preferred Stock Warrants

In January 2023, pursuant to the Merger, the warrants held by the Flame Warrant Holders became exercisable for 6,530 shares of Leap’s common stock (the “January 2023 Common Stock Warrants”). The January 2023 Common Stock Warrants have an exercise price of $6.78 per share and expire in February 2025. The January 2023 Common Stock Warrants qualify for equity classification.

Also in January 2023, pursuant to the Merger, the warrants held by the Flame Warrant Holders became exercisable for 443 shares of Series X Preferred Stock (the “January 2023 Series X Preferred Stock Warrants”). Upon obtaining Stockholder Approval for the conversion of the Series X Preferred Stock and the one-for-ten reverse stock split, each share of Series X Preferred Stock converted into 100 shares of Common Stock. The January 2023 Series X Preferred Stock Warrants have an exercise price of $6.78 per share and expire in February 2025.

The Company initially recorded the January 2023 Series X Preferred Stock Warrants as a liability on the Effective Date and the warrant liability was subsequently remeasured to fair value at each reporting date and on the date on which Stockholder Approval to convert shares of Series X Preferred Stock into shares of common stock was obtained. On June 21, 2023, after obtaining stockholder approval for the conversion of the Series X Preferred Stock into common stock, the January 2023 Series X Preferred Stock Warrants were reclassified from liability to equity.

Changes in the fair value of the warrant liability are recognized as gains (losses) in the Company’s consolidated statement of operations. During the three months ended March 31, 2023, the Company recorded a gain of $50 in its condensed consolidated statement of operations.

Accrued expenses consist of the following:


	March 31,		December 31,
	2024		2023
Clinical trials	$	1,932	$	2,522
Professional fees		130		254
Payroll and related expenses		1,994		3,181
Accrued expenses	$	4,056	$	5,957

5. Leases

The Company has an operating lease for real estate in the United States and does not have any finance leases. The Company’s leases may contain options to renew and extend lease terms and options to terminate leases early. Reflected in the right-of-use asset and lease liability on the Company’s consolidated balance sheets are the periods provided by renewal and extension options that the Company is reasonably certain to exercise, as well as the periods provided by termination options that the Company is reasonably certain to not exercise.

The Company’s existing lease expires in July 2025 and includes variable lease and non-lease components that are not included in the right-of-use asset and lease liability and are reflected as an expense in the period incurred. Such payments primarily include common area maintenance charges and increases in rent payments that are driven by factors such as future changes in an index (e.g., the Consumer Price Index).

In calculating the present value of future lease payments, the Company utilized its incremental borrowing rate based on the lease term. The Company has elected to account for each lease component and its associated non-lease components as a single lease component and has allocated all of the contract consideration across lease components only. This will potentially result in the initial and subsequent measurement of the balances of the right-of-use asset and lease liability for leases being greater than if the policy election was not applied. The Company has an existing net lease in which the non-lease components (e.g. common area maintenance, maintenance, consumables, etc.) are paid separately from rent based on actual costs incurred and therefore are not included in the right-of-use asset and lease liability and are reflected as an expense in the period incurred. During the three months ended March 31, 2024, the Company extended the term of its operating lease and recorded an additional right-of-use asset and lease liability of $420. As of March 31, 2024, a right-of-use asset of $577 and lease liability of $584 are reflected on the condensed consolidated balance sheet. The Company recorded rent expense of $110 and $114, respectively, during the three months ended March 31, 2024 and 2023. Cash paid for amounts included in the measurement of lease liabilities was $114 and $112, respectively, during the three months ended March 31, 2024 and 2023.

Future lease payments under non-cancelable operating leases as of March 31, 2024 are detailed as follows:


Future Operating Lease Payments
2024		348
2025		273
Total Lease Payments		621
Less: imputed interest		(37)
Total operating lease liabilities	$	584

6. Warrants

As of March 31, 2024, the number of shares of common stock issuable upon the exercise of outstanding warrants, consisted of the following:


March 31, 2024

	5,008,144

2019 Warrants

During the three months ended March 31, 2023, the Company redeemed 10,000 of the 2019 Warrants at a purchase price of $2.90 per share.

January 2023 Common Stock Warrants

January 2023 Series X Preferred Stock Warrants

In January 2023, pursuant to the Merger, the warrants held by the Flame Warrant Holders also became exercisable for 443 shares of Series X Preferred Stock (the “January 2023 Series X Preferred Stock Warrants”). Following Stockholder Approval, each share of Series X Preferred Stock converted into 100 shares of common stock during the three months ended June 30, 2023. The January 2023 Series X Preferred Stock Warrants have an exercise price of $6.78 per share and expire in February 2025.

The Company initially recorded the January 2023 Series X Preferred Stock Warrants as a liability on its condensed consolidated balance sheet as of the Effective Date and subsequently remeasured the warrant liability to fair value at each reporting date and on the date Stockholder Approval was obtained to convert shares of Series X Preferred Stock into shares of common stock. Changes in the fair value of the warrant liability were recognized as gains (losses) in the Company’s consolidated statement of operations. During the three months ended March 31, 2023, the Company recorded a gain of $50 in its condensed consolidated statement of operations.

During the three months ended June 30, 2023, upon obtaining Stockholder Approval, the January 2023 Series X Preferred Stock Warrants were converted into common stock warrants and reclassified from liability to equity.

7. Common Stock

Each share of common stock entitles the holder to one vote on all matters submitted to a vote of the Company’s stockholders. Common stockholders are entitled to receive dividends, as may be declared by the Board of Directors, if any, subject to the preferential dividend rights of the preferred stockholders. Through March 31, 2024, no dividends have been declared for shares of common stock.

Acquisition of Flame – January 2023

On January 17, 2023 Leap acquired 100% of the outstanding equity of Flame. Pursuant to the Merger, Leap issued to Flame Stockholders 1,972,901 shares of common stock. The Company also issued Series X Preferred Stock to Flame Stockholders pursuant to the Merger (see Note 3).

8. Equity Incentive Plans

Equity Incentive Plans

On January 20, 2017, the Company’s stockholders approved the 2016 Equity Incentive Plan (the “2016 Plan”). Beginning on January 1, 2018, the number of shares of common stock authorized for issuance pursuant to the 2016 Plan was increased each January 1 by an amount equal to 4% of the Company’s outstanding common stock as of the end of the immediately preceding calendar year or such lesser amount as determined by the compensation committee of the Company’s Board of Directors.

On June 16, 2022, the Company’s stockholders approved the 2022 Equity Incentive Plan (the “2022 Plan”), which provides for a total of 750,000 new shares of the Company’s common stock to be granted. In addition, on June 16, 2023, stockholders approved 2,250,000 new shares of the Company’s common stock to be added to the 2022 Plan for future issuance.

As of March 31, 2024, there were 551,964 shares available for grant under the Company’s equity incentive plans.

A summary of stock option activity under the Equity Plans is as follows:


			Weighted
			Average	Weighted		Aggregate
			Exercise Price	Average Remaining		Intrinsic
	Options		Per Share	Life in Years		Value
Outstanding at December 31, 2023	3,384,366	$	13.97	8.40	$	3,431
Granted	1,632,500	$	2.68
Exercised	(10,557)	$	2.77
Forfeited	(138,325)	$	5.65
Outstanding at March 31, 2024	4,867,984	$	10.44	8.70	$	666
Options exercisable at March 31, 2024	1,659,948	$	24.51	7.13
Options vested and expected to vest at March 31, 2024	4,867,984	$	10.44	8.70	$	666

The grant date fair value of the options granted during the three months ended March 31, 2024 and 2023 was estimated at the date of grant using the Black-Scholes option valuation model. The expected life was estimated using the “simplified” method as defined by the SEC’s Staff Accounting Bulletin 107, Share-Based Payment. The expected volatility was based on the historical volatility of the Company. The risk-free interest rate was based on the continuous rates provided by the U.S. Treasury with a term approximating the expected life of the option. The expected dividend yield was 0% because the Company does not expect to pay any dividends for the foreseeable future. The Company elected the straight-line attribution method in recognizing the grant date fair value of options issued over the requisite service periods of the awards, which are generally the vesting periods.

The weighted average grant date fair value for the stock options granted during the three months ended March 31, 2024 and 2023 was $2.12 and $1.39 per share, respectively.

The assumptions that the Company used to determine the grant-date fair value of stock options granted to employees and directors during the three months ended March 31, 2024 and 2023 were as follows, presented on a weighted average basis:


	Three Months Ended March 31,
	2024		2023

Expected volatility	92.84	%	89.99	%
Weighted average risk-free interest rate	4.00	%	3.56	%
Expected dividend yield	0.00	%	0.00	%
Expected term (in years)	6.44		6.42

Stock options generally vest over a three or four year period, as determined by the compensation committee of the Board of Directors at the time of grant. The options expire 10 years from the grant date. As of March 31, 2024, there was approximately $7,604 of unrecognized compensation cost related to non-vested stock options, which is expected to be recognized over a remaining weighted-average period of approximately 2.25 years.

Restricted Stock Units (“RSUs”)

The Company did not grant any RSUs during the three months ended March 31, 2024 and 2023.

The following table presents RSU activity under the 2016 Plan during the three months ended March 31, 2024:


		Weighted

Forfeited	(7,500)	$	19.40
Outstanding at March 31, 2024	227,500	$	19.29

As of March 31, 2024, there were 227,500 shares outstanding covered by RSUs that are expected to vest with a weighted average grant date fair value of $19.29 per share and an aggregate grant date fair value of approximately $4,388. As of March 31, 2024, there was approximately $1,249 of unrecognized compensation costs related to RSUs granted to employees, which are expected to be recognized as expense over a remaining weighted average period of 0.87 years.

The Company recognized stock-based compensation expense related to the issuance of stock option awards and RSUs to employees and non-employees in the condensed consolidated statements of operations during the three months ended March 31, 2024 and 2023 as follows:

Stock Based Compensation Expense


	Three Months Ended March 31,

All warrants exercisable for common stock participate on a one-for-one basis and shares and warrants exercisable for Series X Preferred Stock issued participate on an as converted basis with common stock in the distribution of dividends, if and when declared by the board of directors, on the Company’s common stock. For purposes of computing EPS, these securities are considered to participate with common stock in earnings of the Company. Therefore, the Company calculates basic and diluted EPS using the two-class method. Under the two-class method, net income for the period is allocated between common stockholders and participating securities according to dividends declared and participation rights in undistributed earnings. No income was allocated to the warrants and Series X Preferred Stock for the three months ended March 31, 2024 and 2023, as results of operations were a loss for the period.

The Company’s potentially dilutive securities include RSUs, stock options and warrants. These securities were excluded from the computations of diluted net loss per share for the three months ended March 31, 2024 and 2023, as the effect would be to reduce the net loss per share. The following table includes the potential shares of common stock, presented based on amounts outstanding at each period end, that were excluded from the computation of diluted net loss per share attributable to common stockholders for the periods indicated because including them would have had an anti-dilutive effect:


	Three Months Ended March 31,
	2024	2023
Restricted stock units to purchase common stock	227,500	292,500
Options to purchase common stock	4,867,984	910,151
Warrants to purchase common stock	3,586,373	3,542,098
	8,681,857	4,744,749

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

The following Management’s Discussion and Analysis of Financial Condition and Results of Operations (“MD&A”) is intended to help the reader understand our results of operations and financial condition. This MD&A is provided as a supplement to, and should be read in conjunction with, our condensed consolidated financial statements and the accompanying notes thereto and other disclosures included in this Quarterly Report on Form 10-Q, including the disclosures under Part II, Item IA “Risk Factors,” and our audited condensed consolidated financial statements and the accompanying notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2023, which was filed with the Securities and Exchange Commission, or the SEC, on March 18, 2024. Our condensed consolidated financial statements have been prepared in accordance with U.S. GAAP and, unless otherwise indicated, amounts are presented in U.S. dollars.

Company Overview

We are a biopharmaceutical company developing biomarker-targeted antibody therapies designed to treat patients with cancer by inhibiting fundamental tumor-promoting pathways, targeting cancer-specific cell surface molecules, and harnessing the immune system to attack cancer cells. Our strategy is to identify, acquire, and develop molecules that will rapidly translate into high impact therapeutics that generate durable clinical benefit and enhanced patient outcomes.

Our lead clinical stage program is DKN-01, a monoclonal antibody that inhibits Dickkopf-related protein 1, or DKK1. We are currently studying DKN-01 in multiple ongoing clinical trials in patients with esophagogastric cancer, gynecologic cancers, or colorectal cancer. Our second clinical stage program is FL-301, a monoclonal antibody that targets cells that express Claudin18.2 on their cell surface. We also have two preclinical antibody programs, FL-302 and FL-501.

We intend to apply our extensive experience identifying and developing transformational products to build a pipeline of programs that have the potential to change the practice of cancer medicine.

We have devoted substantially all of our resources to development efforts relating to our product candidates, including manufacturing and conducting clinical trials of our product candidates, providing general and administrative support for these operations and protecting our intellectual property. We do not have any products approved for sale and have not generated any revenue from product sales. We have funded our operations primarily through proceeds from our sales of common stock and preferred stock and proceeds from the issuance of notes payable.

Recent Developments

Since December 31, 2023, we have continued to make progress with the development of DKN-01 and our business strategy.

Business Update

●

Completed a $40 million private placement. In April 2024, we entered into a securities purchase agreement with a select group of institutional investors to issue and sell an aggregate of 12,660,993 shares of our common stock at a price of $2.82 per share and pre-funded warrants to purchase 1,523,404 shares of common stock at a price of $2.819 per share of common stock issuable upon exercise of the pre-funded warrants, in a private placement. Net proceeds from the private placement were approximately $37.2 million with participation from new and existing investors, including Gilead Sciences, Inc., a life sciences-focused investor, Samsara BioCapital, 683 Capital Partners, LP, Laurion Capital Management, and Rock Springs Capital. The net proceeds from this financing, combined with existing cash, cash equivalents and marketable securities, are expected to fund our operating and capital expenditures into the second quarter of 2026 and enable expansion of the DKN-01 DeFianCe clinical trial and development program.

DKN-01 Development Update

●

Presented initial clinical data from Part A of the DeFianCe Study of DKN-01 plus bevacizumab and chemotherapy in colorectal cancer (CRC) patients. We presented initial data from Part A of the DeFianCe study, a Phase 2 study evaluating DKN-01 in combination with standard of care (“SOC”) bevacizumab and chemotherapy in second-line (“2L”) patients with advanced microsatellite stable (“MSS”) CRC patients at the 2024 American Society of Clinical Oncology (“ASCO”) Gastrointestinal Cancers Symposium, held in San Francisco on January 18-20, 2024 and during our conference call on January 23, 2024.

Table of Contents

●

Key Findings (as of the December 6, 2023 data cutoff):

o

Across all patients enrolled (n=33):

◾

Overall response rate (“ORR”) among response-evaluable patients (n=27) was 30% and disease control rate (“DCR”) was 93%, including 8 partial responses (“PR”) and 17 patients with a best response of stable disease (“SD”)

◾

Median progression-free survival (“PFS”) was 6.3 months

◾

9 patients remained on therapy and were beyond 8.5 months

o

Enhanced activity in patients with left-sided tumors (n=25), a group that has more frequent activation of the Wnt pathway modulated by DKK1

◾

33% ORR and 100% DCR in response-evaluable population (7 PRs, 14 SDs)

◾

Preliminary median PFS of 8.6 months (9 patients continuing therapy within subgroup)

o

Compelling ORR, DCR and PFS in patients with rectal/rectosigmoid carcinomas (n=15), a population with increasing incidence among young people and shown to have the highest DKK1 levels:

◾

46% ORR and 100% DCR in response-evaluable population (6 PRs, 7 SDs)

◾

Preliminary median PFS of 9.4 months (6 patients continuing therapy within subgroup)

◾

Higher baseline plasma DKK1 levels correlated with improved responses

o

DKN-01 plus bevacizumab and chemotherapy was well-tolerated, with a majority of DKN-01 related events being low grade (Grade 1/2)

●

Part B of the DeFianCe Study of DKN-01 plus bevacizumab and chemotherapy in CRC patients is ongoing, with enrollment expanded to 180 patients and expected to be completed in late Q3 or early Q4 2024. We expanded the randomized controlled Part B of the DeFianCe study from 130 to 180 patients and included PFS in the subpopulation of patients with left-sided CRC as an additional primary endpoint. We expect to complete enrollment in late Q3 or early Q4 2024 with data expected in mid-2025. As of May 8, 2024, 114 patients have enrolled in Part B.

●

Completion of enrollment in the randomized controlled Part C of the DisTinGuish study evaluating DKN-01 in combination with tislelizumab, BeiGene’s anti-PD-1 antibody, and chemotherapy in patients with advanced gastroesophageal junction and gastric cancer. Part C of the DisTinGuish study is a Phase 2, randomized, open-label, multicenter study of DKN-01 in combination with tislelizumab and chemotherapy in first-line patients with advanced gastroesophageal adenocarcinoma. Part C enrolled 170 first-line, HER2-negative patients randomized 1:1 to evaluate DKN-01 in combination with tislelizumab and SOC chemotherapy, compared to tislelizumab and SOC chemotherapy alone. The primary objective is PFS in DKK1-high and in all patients. Secondary objectives of Part C include OS and ORR as measured by RECIST v1.1 in DKK1-high and in all patients. We expect to report initial data from Part C of the DisTinGuish study in the second half of 2024 or early 2025 when the PFS data is mature.

Financial Overview

Research and Development Expenses

Our research and development activities have included conducting nonclinical studies and clinical trials, manufacturing development efforts and activities related to regulatory filings for our product candidates, primarily DKN-01. We recognize research and development expenses as they are incurred. Our research and development expenses during the three months ended March 31, 2024 consisted primarily of:

●

salaries and related overhead expenses for personnel in research and development functions, including costs related to stock-based compensation;

●

fees paid to consultants and CROs for our nonclinical and clinical trials, and other related clinical trial fees, including but not limited to laboratory work, clinical trial database management, clinical trial material management and statistical compilation and analysis;

●

costs related to acquiring and manufacturing clinical trial material; and

●

costs related to compliance with regulatory requirements.

We plan to increase our research and development expenses for the foreseeable future as we continue the development of DKN-01 and any other product candidates, subject to the availability of additional funding.

Our direct research and development expenses are tracked on a program-by-program basis and consist primarily of internal and external costs, such as employee costs, including salaries and stock-based compensation, other internal costs, fees paid to consultants, central laboratories, contractors and CROs in connection with our clinical and preclinical trial development activities. We use internal resources to manage our clinical and preclinical trial development activities and perform data analysis for such activities.

We participate, through our subsidiary in Australia, in the Australian government’s research and development (“R&D”) Incentive program (“R&D Incentive Program”), such that a percentage of our eligible research and development expenses are reimbursed by the Australian government as a refundable tax offset and such incentives are reflected as other income.

The table below summarizes our research and development expenses incurred by development program and the R&D Incentive income for the three months ended March 31, 2024 and 2023:


	Three Months Ended March 31,

Table of Contents

The successful development of our clinical product candidates is highly uncertain. At this time, we cannot reasonably estimate the nature, timing or costs of the efforts that will be necessary to complete the remainder of the development of any of our product candidates or the period, if any, in which material net cash inflows from these product candidates may commence. This is due to the numerous risks and uncertainties associated with developing drugs, including the uncertainty of:

●

the scope, rate of progress and expense of our ongoing, as well as any additional, clinical trials and other research and development activities;

●

future clinical trial results; and

●

the timing and receipt of any regulatory approvals.

A change in the outcome of any of these variables with respect to the development of a product candidate could result in a significant change in the costs and timing associated with the development of that product candidate. For example, if the FDA or another regulatory authority were to require us to conduct clinical trials beyond those that we currently anticipate will be required for the completion of clinical development of a product candidate, or if we experience significant delays in enrollment in any of our clinical trials, we could be required to expend significant additional financial resources and time on the completion of clinical development.

General and Administrative Expenses

General and administrative expenses consist primarily of salaries and related costs, including stock-based compensation, for personnel in executive, finance and administrative functions. General and administrative expenses also include direct and allocated facility-related costs as well as professional fees for legal, patent, consulting, accounting and audit services.

We anticipate that our general and administrative expenses will increase in the future as we increase our headcount to support our continued research activities and development of our product candidates. We also anticipate that we will incur increased accounting, audit, legal, regulatory, compliance, director and officer insurance costs as well as investor and public relations expenses associated with being a public company.

Interest income

Interest income consists primarily of interest income earned on cash and cash equivalents.

Research and development incentive income

Research and development incentive income includes payments under the R&D Incentive Program from the government of Australia. The R&D Incentive Program is one of the key elements of the Australian government’s support for Australia’s innovation system. It was developed to assist businesses in recovering some of the costs of undertaking research and development. The research and development tax incentive provides a tax offset to eligible companies that engage in research and development activities.

Companies engaged in research and development may be eligible for either:

●

a refundable tax offset at a rate of 18.5% above the company’s tax rate for entities with income of less than A$20 million per annum; or

●

a non-refundable tax offset for all other entities which is a progressive marginal tiered R&D intensity threshold. Increasing rates of benefit apply for incremental research and development expenditure by intensity:

●

0 to 2% intensity: an 8.5% premium to the company’s tax rate

●

Greater than 2% intensity: a 16.5% premium to the company’s tax rate;

We recognize as income the amount we expect to be reimbursed for qualified expenses.

Foreign currency translation adjustment

Foreign currency translation adjustment consists of gains (losses) due to the revaluation of foreign currency transactions attributable to changes in foreign currency exchange rates associated with our Australian subsidiary.

Critical Accounting Policies and Estimates

Our condensed consolidated financial statements are prepared in accordance with GAAP. The preparation of our financial statements and related disclosures requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenue, costs and expenses, and the disclosure of contingent assets and liabilities in our financial statements. We base our estimates on historical experience, known trends and events and various other factors that we believe are 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. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions or conditions.

Our critical accounting policies are described under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations— Critical Accounting Policies and Significant Judgments and Estimates” in our Annual Report on Form 10-K filed with the SEC on March 18, 2024, and the notes to the condensed consolidated financial statements appearing elsewhere in this Quarterly Report on Form 10-Q. We believe that of our critical accounting policies, the following accounting policies involve the most judgment and complexity:

●

accrued research and development expenses;

●

research and development incentive receivable; and

●

stock-based compensation.

Total research and development expenses	$	11,299	$	38,942	$	(27,643)

Research and development expenses were $11.3 million for the three months ended March 31, 2024, compared to $38.9 million for the three months ended March 31, 2023. The decrease of $27.6 million in R&D expenses during the three months ended March 31, 2024 as compared to the same period in 2023, was primarily due to $29.6 million of in-process research and development (“IPR&D”) acquired in the Flame merger which we expensed during the three months ended March 31, 2023. In addition, there was a decrease of $0.4 million in manufacturing costs related to clinical trial material and manufacturing campaigns and a decrease of $0.1 million in consulting fees associated with research and development activities. These decreases were partially offset by an increase of $2.0 million in clinical trial costs and an increase of $0.5 million in payroll and other related expenses due to an increase in headcount of our R&D full-time employees.

General and Administrative Expenses

General and administrative expenses were $3.5 million for the three months ended March 31, 2024, compared to $3.8 million for the three months ended March 31, 2023. The decrease of $0.3 million in general and administrative expenses during the three months ended March 31, 2024 as compared to the same period in 2023, was due to a decrease of $0.3 million in professional fees associated with our business development activities.

Interest Income

During the three months ended March 31, 2024, we recorded interest income of $0.8 million. During the three months ended March 31, 2023, we recorded interest income of $0.8 million.

Australian Research and Development Incentives

We recorded R&D incentive income of $0.2 million and $0.3 million during the three months ended March 31, 2024 and 2023, respectively, based upon the applicable percentage of eligible research and development activities under the R&D Incentive Program, which expenses included the cost of manufacturing clinical trial material.

The R&D incentive receivable has been recorded as “Research and development incentive receivable” in the condensed consolidated balance sheets.

Foreign Currency Loss

During the three months ended March 31, 2023, we recorded foreign currency transaction losses of $0.3 million. During the three months ended March 31, 2024, we recorded an immaterial amount of foreign currency transaction losses. Foreign currency transaction losses are due to changes in the Australian dollar exchange rate related to activities of the Australian entity.

Financial Position, Liquidity and Capital Resources

Since our inception, we have been engaged in organizational activities, including raising capital, and research and development activities. We do not yet have a product that has been approved by the Food and Drug Administration (the “FDA”), have not yet achieved profitable operations, nor have we ever generated positive cash flows from operations. There is no assurance that profitable operations, if achieved, could be sustained on a continuing basis. Further, our future operations are dependent on the success of efforts to raise additional capital, our research and commercialization efforts, regulatory approval, and, ultimately, the market acceptance of our products.

In accordance with Accounting Standards Codification (“ASC”) 205-40, Going Concern, we have evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about our ability to continue as a going concern within one year after the date that the condensed consolidated financial statements are issued. As of March 31, 2024, we had cash and cash equivalents of $54.9 million. In April of 2024, we completed a private placement (“April 2024 Private Placement”), resulting in net proceeds of approximately $37.2 million, net of underwriting discounts and commissions and estimated offering expenses payable by us. Additionally, we had an accumulated deficit of $413.4 million at March 31, 2024, and during the three months ended March 31, 2024, we incurred a net loss of $13.8 million. We expect to continue to generate operating losses in the foreseeable future. We believe that our cash and cash equivalents of $54.9 million as of March 31, 2024, together with the net proceeds of approximately $37.2 million from the April 2024 Private Placement, will be sufficient to fund our operating expenses for at least the next 12 months from the issuance of this report on Form 10-Q.

In addition, to support our future operations, we will seek additional funding through public or private equity financings or government programs and will seek funding or development program cost-sharing through collaboration agreements or licenses with larger pharmaceutical or biotechnology companies. If we do not obtain additional funding or development program cost-sharing, we could be forced to delay, reduce or eliminate certain clinical trials or research and development programs, reduce or eliminate discretionary operating expenses, and delay company and pipeline expansion, which could adversely affect our business prospects. The inability to obtain funding, as and when needed, could have a negative impact on Leap’s financial condition and our ability to pursue our business strategies.

Cash Flows

Net increase (decrease) in cash and cash equivalents	$	(15,722)	$	36,538

Operating activities. Net cash used in operating activities for the three months ended March 31, 2024 was primarily related to our net loss from the operation of our business of $13.8 million and net changes in working capital, including a decrease in accounts payable and accrued expenses of $2.4 million, an increase of $0.3 million in prepaid expenses and other assets, an increase in research and development incentive receivable of $0.2 million and a decrease in lease liabilities of $0.1 million. These changes were partially offset by noncash stock-based compensation expense of $1.2 million and a decrease in non-cash operating lease expense of $0.1 million.

Net cash used in operating activities for the three months ended March 31, 2023 was primarily related to our net loss from the operation of our business of $41.9 million and net changes in working capital, including a decrease in accounts payable and accrued expenses of $2.2 million, an increase in research and development incentive receivable of $0.3 million, an increase in prepaid expenses and other assets of $0.2 million and a decrease in lease liabilities of $0.1 million. These changes were partially offset by a noncash IPR&D expense of $29.6 million, noncash stock based compensation expense of $1.3 million, a decrease of $0.7 million in other assets, change in a right-of-use asset of $0.1 million and foreign currency transaction losses of $0.3 million.

Table of Contents

Investing Activities. Net cash provided by investing activities for the three months ended March 31, 2023 was related to $50.4 million of cash acquired in connection with the acquisition of Flame and payment of direct and incremental costs of $1.0 million associated with the acquisition of Flame. There were no investing activities during the three months ended March 31, 2024.

Financing Activities. Net cash provided by financing activities for the three months ended March 31, 2024 consisted of an immaterial amount of proceeds upon the exercise of stock options. Net cash used in financing activities for the three months ended March 31, 2023 consisted of an immaterial amount we paid for the redemption of 10,000 of the 2019 warrants.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Not Applicable.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) is (1) recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms and (2) accumulated and communicated to our management, including our President and Chief Executive Officer, who is also serving as Chief Financial Officer and therefore currently serves as both our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure.

As of March 31, 2024, our management, with the participation of our Chief Executive Officer, who is also serving as Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) using the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control—Integrated Framework (2013 Framework). Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Our principal executive officer and principal financial officer has concluded, based upon the evaluation described above, that, as of March 31, 2024, our disclosure controls and procedures were effective to ensure that information required to be disclosed by us in reports the Company files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the SEC, and that such material information is accumulated and communicated to the Company’s management, including its principal executive officer and principal financial officer, to allow timely decisions regarding required disclosure.

Changes in Internal Control over Financial Reporting

During the three months ended March 31, 2024, there were no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that materially affected, or are reasonably likely to affect, internal control over financial reporting.
