A.	Description of Business, Basis of Presentation, and Significant Transactions

 

Organization

 

Zevra Therapeutics, Inc. (the “Company” or “Zevra”) is a commercial-stage company focused on addressing unmet needs for the treatment of rare diseases. The Company has a diverse portfolio of products and product candidates, which includes clinical stage pipeline and commercial stage assets. On  September 20, 2024, the U.S. Food and Drug Administration (“FDA”) approved the New Drug Application (“NDA”) for MIPLYFFA® (arimoclomol), an orally-delivered treatment for Niemann-Pick disease type C (“NPC”), which is an ultra-rare and progressive neurodegenerative disease. MIPLYFFA, the first FDA-approved treatment for NPC, is indicated for use in combination with miglustat for the treatment of neurological manifestations of NPC in adult and pediatric patients two years of age and older. MIPLYFFA has also been granted orphan medicinal product designation for the treatment of NPC by the European Commission.

 

In addition, the Company received a transferable rare pediatric disease priority review voucher (“PRV”) in conjunction with the approval of MIPLYFFA. On  February 27, 2025, the Company and its subsidiary, Zevra Denmark A/S, entered into an asset purchase agreement with a buyer (the “PRV Transfer Agreement”), pursuant to which the Company agreed to sell the PRV to the buyer for $150.0 million, payable in cash, upon the closing of the sale. On April 1, 2025, the asset sale was consummated, resulting in net proceeds of $148.3 million to the Company. As the title of the PRV did not transfer until April 1, 2025, the sale was effective subsequent to the balance sheet date and, therefore, not included in the financial statements as of and for the three months ended March 31, 2025.

 

The Company's other commercial stage asset, OLPRUVA® (sodium phenylbutyrate) for oral suspension, is approved by the FDA for the treatment of certain urea cycle disorders (“UCDs”). Additionally, the Company has a pipeline of investigational product candidates, including celiprolol for the treatment of vascular Ehlers-Danlos syndrome in patients with a confirmed type III collagen mutation and KP1077, the Company's clinical development product candidate being developed to treat idiopathic hypersomnia (“IH”), a rare neurological sleep disorder, and narcolepsy. KP1077 has a sole active pharmaceutical ingredient of serdexmethylphenidate (“SDX”), the Company's proprietary prodrug of d-methylphenidate (“d-MPH”). The FDA has granted KP1077 orphan drug designation for the treatment of IH.

 

Basis of Presentation

 

The Company prepared the unaudited condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”) and, in the Company’s opinion, reflect all adjustments, including normal recurring items that are necessary. All significant intercompany accounts and transactions have been eliminated in consolidation.

B.	Summary of Significant Accounting Policies

 

Use of Estimates

 

The preparation of these unaudited condensed consolidated financial statements in conformity with U.S. GAAP requires the Company to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

 

On an ongoing basis, the Company evaluates its estimates and assumptions, including those related to revenue recognition, the useful lives of property and equipment, the recoverability of long-lived assets, the incremental borrowing rate for leases, and assumptions used for purposes of determining stock-based compensation, income taxes, the fair value of the derivative and warrant liability and discount and rebate liabilities, among others. The Company bases its estimates on historical experience and on various other assumptions that it believes to be reasonable, the results of which form the basis for making judgments about the carrying value of assets and liabilities.

Arimoclomol French AC

 

Net revenue includes revenue from the sale of arimoclomol for the treatment of NPC under the remunerated expanded access program in France, Accès Compassionnel (“French AC”). An expanded access program is a program giving specific patients access to a drug, which is not yet approved for commercial sale. Only drugs targeting serious or rare indications and for which there is currently no appropriate treatment are considered for expanded access programs. Further, to be considered for the expanded access program, the drug must have proven efficacy and safety and must either be undergoing price negotiations or seeking marketing approval.

 

In accordance with ASC 606, the Company recognizes revenue when fulfilling its performance obligation under the French AC by transferring control of promised goods or services to its customer, in an amount that reflects the consideration that the Company expects to receive in exchange for those goods or services. In determining when the customer obtains control of the product, the Company considers certain indicators, including whether the Company has a present right to payment from the customer, whether title and/or significant risks and rewards of ownership have transferred to the customer and whether customer acceptance has been received. Revenue is recognized net of sales deductions, including discounts, rebates, applicable distributor fees, and revenue-based taxes.

 

The French Health Authorities and the manufacturer have agreed to a price for sales under the French AC, but the final transaction price depends on the terms and conditions in the contracts with the French Health Authorities, following market approval. Any excess in the price charged by the manufacturer compared to the price agreed with the health authorities once the drug product is approved in France must be repaid. The repayment is considered in the clawback liability (rebate). An estimate of net revenue and clawback liability are recognized using the ‘expected value’ method. Accounting for net revenue and clawback liability requires determination of the most appropriate method for the expected final transaction price. This estimate also requires assumptions with respect to inputs into the method, including current pricing of comparable marketed products within the rare disease area in France. Management has considered the expected final sales price as well as the price of similar drug products. The Company is operating within a rare disease therapeutic area where there is unmet treatment need and hence a limited number of comparable commercialized drug products. The limited available relevant market information for directly comparable commercialized drugs within rare disease increases the uncertainty in management's estimate.

 

Licensing Agreements

 

The terms of the Company’s licensing agreements typically include one or more of the following: (i) upfront fees; (ii) milestone payments related to the achievement of development, regulatory, or commercial goals; and (iii) royalties on net sales of licensed products. Each of these payments  may result in licensing revenues.

 

As part of the accounting for these agreements, the Company must develop estimates and assumptions that require judgment to determine the underlying stand-alone selling price for each performance obligation, which determines how the transaction price is allocated among the performance obligations. Generally, the estimation of the stand-alone selling price  may include such estimates as independent evidence of market price, forecasted revenues or costs, development timelines, discount rates, and probability of regulatory success. The Company evaluates each performance obligation to determine if they can be satisfied at a point in time or over time, and it measures the services delivered to the licensee, which are periodically reviewed based on the progress of the related program. The effect of any change made to an estimated input component and, therefore, revenue or expense recognized, would be recorded as a change in estimate. In addition, variable consideration (e.g., milestone payments) must be evaluated to determine if it is constrained and, therefore, excluded from the transaction price.

 

Up Front Fees: If a license to the Company’s intellectual property is determined to be distinct from the other performance obligations identified in the arrangement, the Company recognizes revenues from the transaction price 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.

 

Milestone Payments: At the inception of each arrangement that includes milestone payments (variable consideration), 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 would not occur, the associated milestone value is included in the transaction price. Milestone payments that are not within the Company’s or the licensee’s control, such as non-operational developmental and regulatory approvals, are generally not considered probable of being achieved until those approvals are received. At the end of each reporting period, the Company re-evaluates the probability of achievement of milestones that are within its or the licensee’s control, such as operational developmental 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 collaboration revenues and earnings in the period of adjustment. Revisions to the Company’s estimate of the transaction price  may also result in negative licensing revenues and earnings in the period of adjustment.

 

Inventories

 

The value of inventories is recorded at net realizable value. The Company determines the cost of its other inventories, which includes amounts related to materials and manufacturing overhead, on a first-in, first-out basis. Inventories that are not expected to be sold within 12 months are classified as inventories, noncurrent.

 

The Company  may scale-up and make commercial quantities of its product candidates prior to the date it anticipates that such product will receive final regulatory approval. The scale-up and commercial production of pre-launch inventory involves the risk that such products  may not be approved for marketing on a timely basis, or ever. This risk notwithstanding, the Company  may scale-up and build pre-launch inventory of products that have not received final regulatory approval when the Company believes such action is appropriate in relation to the commercial value of the product launch opportunity. We capitalize inventory costs associated with our products prior to regulatory approval when, based on management's judgment, future commercialization is considered probable and the future economic benefit is expected to be realized; otherwise, such costs are expensed as research and development. The determination to capitalize inventory costs is based on various factors, including status and expectations of the regulatory approval process, any known safety or efficacy concerns, potential labeling restrictions, and any other impediments to obtaining regulatory approval. We had no pre-approval inventory on our unaudited condensed consolidated balance sheets as of March 31, 2025, or December 31, 2024. Inventory used in clinical trials is also expensed as research and development expense, when selected for such use. Inventory that can be used in either the production of clinical or commercial products is expensed as research and development costs when identified for use in a clinical manufacturing campaign. The cost of finished goods inventory that is shipped to a customer to support the Company’s patient assistance programs is expensed when those shipments take place. As of  March 31, 2025, and December 31, 2024, the Company did not have pre-launch inventory that qualified for capitalization.

 

---

 

The Company performs an assessment of the recoverability of capitalized inventory during each reporting period and writes down any excess and obsolete inventory to its net realizable value in the period in which the impairment is first identified. Such impairment charges, should they occur, are recorded as a component of cost of product revenue in the unaudited condensed consolidated statements of operations. The determination of whether inventory costs will be realizable requires the use of estimates by management. If actual market conditions are less favorable than projected by management, additional write downs of inventory  may be required. Additionally, the Company’s product is subject to strict quality control and monitoring, which is performed throughout the manufacturing process. In the event that certain batches or units of product do not meet quality specifications, the Company will record a charge to cost of product revenue, to write down any unsaleable inventory to its estimated net realizable value. 

 

Cost of Product Revenue

 

The components of cost of product revenue are royalties and expenses directly attributable to revenue. To date, the Company has generated revenue from product sales of MIPLYFFA and OLPRUVA, reimbursements received under the French AC, royalties or net sales milestone payments generated under the Collaboration and License Agreement with Commave Therapeutics SA (the “AZSTARYS® License Agreement”), and consulting agreements. 

 

Prior to our acquisition of the assets of Orphazyme A/S (“Orphazyme”) in May 2022, Orphazyme had entered into an asset purchase agreement with LadRx Corporation, which was assigned to XOMA (US) LLC, a wholly-owned subsidiary of XOMA Corporation (“XOMA”), in June 2023 (“XOMA License Agreement”), as well as a license agreement with Kansas University (“KU”) and UCLB Business, PLC (“UCLB”) (the “KU/UCLB License Agreement”). Under the XOMA License Agreement, XOMA is entitled to a mid-single digit percentage royalty with respect to net sales of MIPLYFFA. In addition, the Company also pays a low-single digit percentage royalty to KU and UCLB with respect to net sales of MIPLYFFA.

 

Segment and Geographic Information

 

Operating segments are defined as components of an enterprise (business activity from which it earns revenue and incurs expenses) for which discrete financial information is available and regularly reviewed by the chief operating decision maker (“CODM”) in deciding how to allocate resources and in assessing performance. The Company’s CODM is its Chief Executive Officer. The Company views its operations and manages its business as a single operating and reporting segment.

 

Foreign Currency

 

Assets and liabilities are translated into the reporting currency using the exchange rates in effect on the balance sheet dates. Equity accounts are translated at historical rates, except for the change in retained earnings during the year, which is the result of the income statement translation process. Revenue and expense accounts are translated using the weighted average exchange rate during the period. The cumulative translation adjustments associated with the net assets of foreign subsidiaries are recorded in accumulated other comprehensive income/loss in the accompanying unaudited condensed consolidated statements of changes in stockholders’ equity.

 

Debt Issuance Costs

 

Debt issuance costs incurred in connection with financing arrangements are recorded as a reduction of the related debt on the unaudited condensed consolidated balance sheets and amortized over the life of the respective financing arrangement using the effective interest method.

 

Warrants

 

The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in FASB ASC Topic 480, Distinguishing Liabilities from Equity (ASC 480) and FASB ASC Topic 815, Derivatives and Hedging (ASC 815). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company's own stock and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding.

 

For warrants that meet all criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital, on the unaudited condensed consolidated statements of changes in stockholders’ equity at the time of issuance. For warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance, and on each balance sheet date thereafter. Changes in the estimated fair value of the warrants are recognized as a non-cash gain or loss in other expense, net, on the unaudited condensed consolidated statements of operations. The fair value of the warrants was estimated using the Black-Scholes option pricing model.

New Accounting Pronouncements Not Yet Adopted

 

Income Taxes (Topic 740): Improvements to Income Tax Disclosures

 

In  December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which expands disclosures in an entity’s income tax rate reconciliation table and disclosures regarding cash taxes paid both in the U.S. and in foreign jurisdictions. The update will be effective for annual periods beginning after  December 15, 2024. The Company is currently evaluating the impact that this guidance will have on the presentation of its financial statements and accompanying notes.

C.	Segment Information

 

Zevra manages its business activities on a consolidated basis and operates as a single operating segment dedicated to the research and development, manufacturing, commercialization and sale of innovative medicines and therapies. The Company primarily derives its revenue from reimbursements received from product sales of MIPLYFFA and OLPRUVA, reimbursements received under the French AC, royalties or net sales milestone payments generated under the AZSTARYS License Agreement, and consulting agreements. The accounting policies of the segment are the same as those described in Note B.

 

Zevra's CODM is the Company's Chief Executive Officer, Neil F. McFarlane. The CODM uses net loss, as reported in the Company's unaudited condensed consolidated statements of operations, in evaluating performance of its segment and determining how to allocate resources of the Company as a whole, including investing in its research and development, commercialization efforts, and acquisition strategy. The CODM does not review assets in evaluating the results of the segment, and, therefore, such information is not presented.

 

 The following table presents the operating results of the Company's segment:

 

		Three months ended March 31,

E.	Debt Obligations

 

Term Loans

 

On  April 5, 2024 (the “Term Loans Closing Date”), the Company entered into a credit agreement (the “Credit Agreement”) with HCR Stafford Fund II, L.P., HCR Potomac Fund II, L.P., and Perceptive Credit Holdings IV, LP (collectively, the “Lenders”), and Alter Domus (US) LLC, as administrative agent (the “Administrative Agent”).

 

Under the terms of the Credit Agreement, the Lenders provided a senior secured loan facility to the Company in the aggregate principal amount of $100.0 million, which is divided into three tranches as follows: (i) $60.0 million which was funded in full on the Term Loans Closing Date; (ii) $20.0 million which is available to the Company in up to two drawings, each in an amount not to exceed $10.0 million, at the Company’s option until 18 months following the Term Loans Closing Date; and (iii) $20.0 million which was available to the Company upon approval by the FDA of the NDA for MIPLYFFA for the treatment of NPC, at the Company’s option until  December 31, 2024 and which has therefore expired (collectively, the “Term Loans”). 

 

The principal amount of the Term Loans outstanding (the “Outstanding Principal Amount”) will bear interest at a rate equal to 3-Month Term SOFR plus 7.00% per annum. If the net product sales for the calendar year ending  December 31, 2025 exceed $100.0 million, the Outstanding Principal Amount will bear interest at 3-Month Term SOFR plus 6.00% per annum. If the net product sales for the calendar year ending  December 31, 2025 do not exceed $100.0 million, then for any subsequent period of four consecutive fiscal quarters ending on or after  March 31, 2026, in which net product sales exceed $125.0 million, the Outstanding Principal Amount will bear interest at 3-Month Term SOFR plus 6.50% per annum. In all cases, the 3-Month Term SOFR rate will be subject to a floor of 4.00% per annum. Interest will be payable quarterly in arrears on the last day of each calendar quarter. The Company has the option to pay up to 25% of the interest in-kind beginning on the Term Loans Closing Date, through and including  June 30, 2026. The Company has recognized approximately $1.9 million and $1.4 million of interest-in-kind as of March 31, 2025, and December 31, 2024, which is included in long-term debt in the unaudited condensed consolidated balance sheets. The Term Loans will mature on the fifth anniversary of the Term Loans Closing Date. In connection with the Credit Agreement, the Company incurred approximately $2.2 million of costs, which primarily consisted of underwriting, legal and other professional fees, and are included as a reduction to the carrying amount of the related debt liability and are deferred and amortized over the remaining life of the financing using the effective interest method.

 

The Credit Agreement contains customary affirmative and negative covenants by the Company, which, among other things, will require the Company to provide certain financial reports to the Lenders within 60 days after the end of each of the first three fiscal quarters of each fiscal year and 105 days after the end of each fiscal year, meet certain minimum net product sales amounts, and limit the ability of the Company to incur or guarantee additional indebtedness, engage in certain transactions, and effect a consolidation or merger without consent. In addition, as long as the line of credit remains active, the Company must maintain a minimum cash balance of $20.0 million to ensure the Company can meet its immediate capital needs. The obligations of the Company under the Credit Agreement  may be accelerated upon customary events of default, including non-payment of principal, interest, fees and other amounts, covenant defaults, insolvency, material judgments, or inaccuracy of representations and warranties. The Term Loans are secured by a first priority perfected lien on, and security interest in, substantially all current and future assets of the Company. The proceeds of the Term Loans were used to refinance certain existing indebtedness of the Company and its subsidiaries. The Company will use the remaining proceeds to pay fees and expenses related to the debt financing and fund the development and commercialization of MIPLYFFA and OLPRUVA.

 

Long-term debt consisted of the following (in thousands):

 

		March 31,				December 31,
		2025				2024
Notes payable		$	62,053			$	61,552
Unamortized original issue discount			(883	)			(921	)
Less: debt issuance costs			(1,080	)			(1,127	)
		$	60,090			$	59,504

 

 

Future minimum principal payments under the Term Loans as of  March 31, 2025, were as follows (in thousands):

Warrants to Purchase Common Stock

 

The Company has issued warrants to purchase common stock to various third parties, of which 5,483,527 remain outstanding as of March 31, 2025, and are immediately exercisable. These warrants qualify as participating securities under ASC Topic 260, Earnings per Share, and are treated as such in the net loss per share calculation (Note J). The Company  may be required to redeem these warrants for a cash amount equal to the Black-Scholes value of the portion of the warrants to be redeemed (the “Put Option”).

 

In connection with the Merger, in  November 2023, the Company directly issued to certain investors an aggregate of 1,382,489 shares of its common stock, par value $0.0001 per share, and accompanying warrants to purchase up to 1,382,489 shares of its common stock (the “2023 Warrants”) at a combined offering price of $4.34 per share of common stock and the 2023 Warrants and an aggregate of 917,934 shares of its common stock in exchange for the cancellation of a warrant to purchase 2,920,306 shares of common stock of Acer. The 2023 Warrants are immediately exercisable and expire on  November 22, 2028. The Company used the net proceeds of approximately $6.0 million from the offering for general corporate purposes. These warrants are separately exercisable by the warrant holders. While the warrants are outstanding (but unexercised), the warrant holders will participate in any dividend or other distribution of the Company’s assets to its common stockholders by way of return of capital or otherwise. As of March 31, 2025, and December 31, 2024, none of the warrants have been exercised. The warrants have been evaluated to determine the appropriate accounting and classification pursuant to ASC 480 and ASC 815. Generally, freestanding warrants should be classified as (i) liabilities if the warrant terms allow settlement of the warrant exercise in cash and (ii) equity if the warrant terms only allow settlement in shares of common stock.

 

The Company determined that its outstanding warrants and the Put Option should be recorded as a liability and stated at fair value at each reporting period. Changes to the fair value of the warrant liability are recorded through the unaudited condensed consolidated statements of operations as a fair value adjustment related to warrant and CVR liability. As of March 31, 2025, and December 31, 2024, the fair value of the liability associated with these warrants and the Put Option was approximately $13.0 million and $17.8 million, respectively. The fair value adjustment related to these warrants and the Put Option was approximately $4.8 million and $4.6 million of income for the three months ended March 31, 2025, and 2024, respectively. 

H.	Stock-Based Compensation

 

In  November 2014, the Board of Directors of the Company (“the Board”), and in  April 2015, the Company’s stockholders, approved the Company’s 2014 Equity Incentive Plan (the “2014 Plan”), which became effective in  April 2015. The 2014 Plan provides for the grant of stock options, other forms of equity compensation, and performance cash awards. In  June 2021, the Company's stockholders approved an Amended and Restated 2014 Equity Incentive Plan (the “A&R 2014 Plan”), following its adoption by the Board in  April 2021, which among other things added 4,900,000 shares to the maximum number of shares of common stock to be issued under the plan and extended the annual automatic increases (discussed further below) until  January 1, 2031 and eliminated individual grant limits that applied under the 2014 Plan to awards that were intended to comply with the exemption for “performance-based compensation” under Code Section 162(m). The maximum number of shares of common stock that  may be issued under the A&R 2014 Plan was 12,079,711 as of  March 31, 2025. The number of shares of common stock reserved for issuance under the A&R 2014 Plan automatically increases on  January 1 of each year, beginning on  January 1, 2016, and ending on and including  January 1, 2031, by 4% of the total number of shares of the Company’s capital stock outstanding on  December 31 of the preceding calendar year, or a lesser number of shares determined by the Board. Pursuant to the terms of the A&R 2014 Plan, on  January 1, 2025, the common stock reserved for issuance under the A&R 2014 Plan automatically increased by 2,146,828 shares.

 

During the three months ended March 31, 2025, and March 31, 2024, 889,025 and 716,875 stock options were exercised, respectively. 

 

In  June 2021, the Company's stockholders approved an Employee Stock Purchase Plan (the “ESPP”), following its adoption by the Board in  April 2021. The maximum number of shares of common stock that  may be issued under the ESPP is 1,500,000. The first offering period under the ESPP began on  October 1, 2021, and the first purchase date occurred on  May 31, 2022. As of  March 31, 2025, 351,988 shares have been issued under the ESPP.

 

In  January 2023, the Board approved the 2023 Employment Inducement Award Plan (as amended, the “2023 Plan”). The maximum number of shares of common stock that  may be issued under the 2023 Plan was 4,500,000 as of March 31, 2025. 

 

In February 2025, the Board approved the Tenth Amended and Restated Non-Employee Director Compensation Policy (the “Non-Employee Director Compensation Policy”). The equity compensation granted pursuant to the Non-Employee Director Compensation Policy will be granted under the A&R 2014 Plan.

 

Stock-based compensation expense recorded under the A&R 2014 Plan, ESPP and 2023 Plan is included in the following line items in the accompanying unaudited condensed consolidated statements of operations (in thousands):

 

		Three months ended March 31,
		2025				2024
Research and development		$	357			$	853
Selling, general and administrative			2,758				1,266
Total stock-based compensation expense		$	3,115			$	2,119

 

There was no stock-based compensation expense related to performance-based awards recognized during the three months ended March 31, 2025, and 2024.

I.	Fair Value of Financial Instruments

 

The accounting standard for fair value measurements provides a framework for measuring fair value and requires disclosures regarding fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, based on the Company’s principal or, in absence of a principal, most advantageous market for the specific asset or liability.

 

The Company uses a three-tier fair value hierarchy to classify and disclose all assets and liabilities measured at fair value on a recurring basis, as well as assets and liabilities measured at fair value on a non-recurring basis, in periods subsequent to their initial measurement. The hierarchy requires the Company to use observable inputs, when available, and to minimize the use of unobservable inputs when determining fair value. The three tiers are defined as follows:

 

	●	Level 1—Observable inputs that reflect quoted market prices (unadjusted) for identical assets or liabilities in active markets;
	●	Level 2—Observable inputs other than quoted prices in active markets that are observable either directly or indirectly in the marketplace for identical or similar assets and liabilities; and
	●	Level 3—Unobservable inputs that are supported by little or no market data, which require the Company to develop its own assumptions.

 

The carrying amounts of certain financial instruments, including cash and cash equivalents, accounts and other receivables, and accounts payable and accrued expenses approximate their respective fair values due to the short-term nature of such instruments.

 

Assets and Liabilities Measured at Fair Value on a Recurring Basis

 

The Company evaluates its financial assets and liabilities subject to fair value measurements on a recurring basis to determine the appropriate level in which to classify them for each reporting period. This determination requires significant judgments to be made. The following table summarizes the conclusions reached regarding fair value measurements as of March 31, 2025, and December 31, 2024 (in thousands):

 

		Balance as of March 31, 2025				Quoted Prices in Active Markets for Identical Assets (Level 1)				Significant Other Observable Inputs (Level 2)				Significant Unobservable Inputs (Level 3)
CVR liability		$	3,400			$	—			$	—			$	3,400
Warrant liabilities			13,030				—				—				13,030

Warrants

 

The common stock warrant liabilities were recorded at fair value using the Black-Scholes option pricing model. The following assumptions were used in determining the fair value of the warrant liabilities valued using the Black-Scholes option pricing model as of March 31, 2025, and December 31, 2024:

 

		March 31, 2025				December 31, 2024
Risk-free interest rate			3.84% - 4.04%				4.08% - 4.23%
Volatility			57.65% - 65.48%				62.14% - 68.68%
Dividend yield			0	%				0%
Expected term (years)			0.78 - 3.65				1.02 - 3.89
Weighted average fair value		$	2.38			$	3.25

 

---

 

The following table is a reconciliation for the common stock warrant liabilities measured at fair value using Level 3 unobservable inputs (in thousands):

 

Balance as of December 31, 2024		$	17,804
Change in fair value measurement			(4,774	)
Balance as of March 31, 2025		$	13,030

 

For the three months ended March 31, 2025, the changes in fair value of the warrant liabilities primarily resulted from change in the discount rate.

 

Contingent Consideration

 

Contingent consideration liabilities relate to the Company's liabilities arising in connection with the CVRs issued as a result of the Merger. The contingent consideration is classified as Level 3 in the fair value hierarchy. The fair value is measured based on a Monte Carlo simulation or a scenario-based method, depending on the earn-out achievement objectives, utilizing projections about future performance. Significant inputs include volatility and projected financial information, including projections representative of a market participant's view of the expected cash payments associated with the agreed upon regulatory milestones based on probabilities of technical success, timing of the potential milestone events for the compounds, and estimated discount rates.

 

The following table provides a reconciliation of the beginning and ending balances related to the contingent consideration liabilities for the CVRs (dollars in thousands):

 

Balance as of December 31, 2024		$	3,500
Change in fair value measurement			(100	)
Balance as of March 31, 2025		$	3,400

 

For the three months ended March 31, 2025, the changes in fair value of contingent consideration primarily resulted from changes in market data and revenue projections.

 

J.	Net Loss Per Share

 

For all periods presented herein, the Company did not use the two-class method to compute net loss attributable to common stockholders per share of common stock, even though it had issued securities, other than common stock, that contractually entitled the holders to participate in dividends and earnings, because these holders are not obligated to participate in a loss. The two-class method requires earnings for the period to be allocated between common stock and participating securities based upon their respective rights to receive distributed and undistributed earnings.

 

Under the two-class method, for periods with net income attributable to common stockholders, basic net income attributable to common stockholders per share of common stock is computed by dividing the undistributed net income attributable to common stockholders by the weighted average number of shares of common stock outstanding during the period. Undistributed net income attributable to common stockholders is computed by subtracting from net income the portion of current period earnings that participating securities would have been entitled to receive pursuant to their dividend rights had all of the period’s earnings been distributed and subtracting the actual or deemed dividends declared. No such adjustment to earnings is made during periods with a net loss as the holders of the participating securities have no obligation to fund losses. Diluted net income attributable to common stockholders per share of common stock is computed under the two-class method by using the weighted average number of shares of common stock outstanding plus the potential dilutive effects of stock options and warrants. In addition to analyzing under the two class method, the Company analyzes the potential dilutive effect of stock options and warrants, under the treasury-stock method when calculating diluted income (loss) attributable to common stockholders per share of common stock, in which it is assumed that the stock options and warrants convert into common stock at the beginning of the period or date of issuance, if the stock option or warrant was issued during the period. The Company reports the more dilutive of the approaches (two-class or treasury-stock/if-converted) as its diluted net income (loss) attributable to common stockholders per share of common stock during the period.

 

As noted above, for all periods presented herein, the Company did not utilize the two-class approach as the Company was in a net loss position and the holders of the participating securities have no obligation to fund losses. The Company did analyze diluted net loss attributable to common stockholders per share of common stock under the treasury-stock/if-converted method and noted that all outstanding stock options and warrants were anti-dilutive for the periods presented. For all periods presented, basic net loss attributable to common stockholders per share of common stock was the same as diluted net loss attributable to common stockholders per share of common stock.

 

The following securities, presented on a common stock equivalent basis, have been excluded from the calculation of weighted average number of shares of common stock outstanding because their effect is anti-dilutive:

 

		Three months ended March 31,
		2025				2024
Awards under equity incentive plans			7,734,741				4,366,537
Common stock warrants			5,483,527				5,603,729
Total securities excluded from the calculation of weighted average number of shares of common stock outstanding			13,218,268				9,970,266

 

A reconciliation from net loss to basic net loss attributable to common stockholders per share of common stock and diluted net loss attributable to common stockholders per share of common stock for the three months ended March 31, 2025, and 2024, respectively, is as follows (in thousands):

 

		Three months ended March 31,
		2025				2024
Basic and diluted net loss per share of common stock:
Net loss, basic and diluted		$	(3,099	)		$	(16,622	)
Weighted average number of shares of common stock outstanding, basic and diluted			54,096				41,779
Basic and diluted net loss per share of common stock		$	(0.06	)		$	(0.40	)

Leases

 

The Company has operating and finance leases for office space, laboratory facilities and various laboratory equipment, furniture and office equipment and leasehold improvements. The Company determines if an arrangement is a lease at contract inception. Lease assets and lease liabilities are recognized based on the present value of lease payments over the lease term at the commencement date. The Company does not separate lease and non-lease components. Leases with a term of 12 months or less at commencement are not recorded on the unaudited condensed consolidated balance sheets. Lease expense for these arrangements is recognized on a straight-line basis over the lease term. The Company’s leases have remaining lease terms of less than 1 year and up to approximately 4 years, some of which include options to extend the leases for up to 5 years, and some which include options to terminate the leases within 1 year.

M.	Commitments and Contingencies

 

From time to time, the Company is involved in various legal proceedings arising in the normal course of business. For some matters, a liability is not probable, or the amount cannot be reasonably estimated and, therefore, an accrual has not been made. However, for such matters when it is probable that the Company has incurred a liability and can reasonably estimate the amount, the Company accrues and discloses such estimates.

 

Litigation Related to the AZSTARYS License Agreement

 

In  September 2024, the Company became engaged in a legal dispute regarding the AZSTARYS License Agreement. The litigation is currently in the discovery phase. The Company cannot predict with certainty the timing or ultimate outcome of this litigation or its potential impact on the Company's business, financial condition, or results of operations. At this time, the Company has not recorded any accrual for contingent liability associated with this matter. The AZSTARYS License Agreement remains in effect during this litigation, and both parties continue to perform their respective obligations thereunder. However, there can be no assurance that this dispute will not have an adverse impact on the Company's relationship with Commave or on the Company's business. The Company will continue to monitor developments in this matter and will assess the potential impact on the Company's financial statements in future periods. The Company expects to incur significant legal expenses in connection with this litigation, which  may materially affect its results of operations in future periods.

 

As of March 31, 2025, and  December 31, 2024, no accruals were made related to commitments and contingencies.

ITEM 2.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

 

You should read the following discussion and analysis of our financial condition and results of operations together with our unaudited condensed consolidated financial statements and related notes thereto included elsewhere in this Quarterly Report on Form 10-Q. Some of the information contained in this discussion and analysis or set forth elsewhere in this Quarterly Report on Form 10-Q, including information with respect to our plans and strategy for our business and related financing, includes forward-looking statements that involve risks and uncertainties. As a result of many factors, including those factors set forth in Part II, Item 1A. “Risk Factors” of this Quarterly Report on Form 10-Q and Part I, Item 1A. “Risk Factors” of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, filed with the SEC on March 12, 2025, our actual results could differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

 

Overview

 

We are a commercial-stage company focused on addressing unmet needs for the treatment of rare diseases. Our mission is to bring life-changing therapeutics to people living with rare diseases. With data-driven development and commercialization strategies, we are overcoming complex drug development challenges to make new therapies available to the rare disease community. We have a diverse portfolio of products and product candidates, which includes pre-clinical, clinical, and commercial stage assets. Our team has specialized expertise and a track record of success in advancing promising therapies that face complex clinical, regulatory, and commercial challenges with an approach that balances science with patient need.

 

As part of our commitment to serving the rare disease community, in February 2023, we changed our name to Zevra Therapeutics, Inc. Our name, Zevra, is the Greek word for zebra, which is the internationally recognized symbol for rare disease. This name reflects our intense focus and dedication to developing transformational, patient-focused therapies for rare diseases with limited or no treatment options available, or treatment areas with significant unmet needs.

 

Our five-year strategic plan is focused on the continued transformation of Zevra into a leading rare-disease company. In addition to the commercialization of OLPRUVA and the approval and subsequent launch of MIPLYFFA, in the third quarter of 2024 we discontinued our in-house drug discovery activities and closed our laboratory facilities in Iowa and Virginia to prioritize near-term resources for our late-stage clinical development and commercial opportunities. In the future, we plan to outsource our discovery and early development activities and further expand our pipeline through both internal development and through our business development activities to collaborate, partner, and potentially acquire additional assets. We intend to target assets that we believe will allow us to leverage the expertise and infrastructure that we have built to help mitigate risk and enhance our probability of success. If we are successful, expanding our pipeline could be accretive to our value proposition and has the potential to create incremental long-term value for stockholders.

 

During the first quarter of 2025, we withdrew the NDA for APADAZ, our approved product for the treatment of pain based on benzhydrocodone, our prodrug of hydrocodone. While this product has not been commercially available over the last few years, this decision eliminates all regulatory activities needed to maintain the approval, reducing costs for a product where currently there is not an economically viable addressable market. We will continue to optimize and curate our IP portfolio through a variety of avenues to extract value for the benefit of shareholders, as demonstrated through these recent activities. In addition, as part of our ongoing IP portfolio review, we licensed certain IP related to our pre-clinical stage prodrug of dextrorphan in April 2025 to an undisclosed party for an upfront payment of $250,000, potential future regulatory milestones of up to $8.45 million and single-digit royalties on net sales. 

 

On September 20, 2024, the FDA approved the New Drug Application (“NDA”) for MIPLYFFA® (arimoclomol), for use in combination with miglustat for the treatment of neurological manifestations of Niemann-Pick disease type C (“NPC”) in adult and pediatric patients 2 years of age and older. MIPLYFFA is an orally-delivered treatment for NPC, which is an ultra-rare and progressive neurodegenerative disease. In connection with this approval, we received a transferable rare pediatric disease priority review voucher (“PRV”). On April 1, 2025, we consummated the sale of the PRV to a buyer, resulting in net proceeds of $148.3 million to the Company. MIPLYFFA has also been granted orphan medical product designation for the treatment of NPC by the European Commission. In November 2024, MIPLYFFA became commercially available for dispense.

 

On August 30, 2023, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Acer Therapeutics Inc. (“Acer”). On November 17, 2023 (the “Closing Date”), we completed the acquisition of Acer (the “Merger”). Pursuant to the Merger Agreement, Acer continues as a wholly-owned subsidiary of Zevra. The Merger included the acquisition of OLPRUVA® (sodium phenylbutyrate) for oral suspension, which was approved by the FDA on December 27, 2022, for the treatment of certain urea cycle disorders (“UCDs”). In addition, we acquired Acer's pipeline of investigational product candidates, including celiprolol for the treatment of Vascular Ehlers-Danlos syndrome (“VEDS”) in patients with a confirmed type III collagen (COL3A1) mutation.

 

In May 2022, we purchased all of the assets and operations of Orphazyme A/S (“Orphazyme”) related to arimoclomol and agreed to assume an estimated reserve clawback liability of $5.2 million related to revenue generated from Orphazyme’s program in France, Accès Compassionnel (“French AC”).

 

 

Our Product Candidates and Approved Products

 

We have built a diverse portfolio of products and product candidates through a combination of internal development and strategic investments through acquisition. For example, we have employed our proprietary Ligand Activated Technology platform to develop approved products (e.g., AZSTARYS) and clinical development candidates (KP1077IH and KP1077N). Through our business development efforts, we have added commercial products (MIPLYFFA and OLPRUVA) and a clinical development candidate (celiprolol). We furthermore have a variety of product candidates and compounds that are clinical-stage and designed to address a variety of rare diseases and other indications.

 

Current commercial products and active development assets are summarized in the table below:

These anticipated milestones are based on information currently available to us. Our current plans and expectations are subject to a number of uncertainties, risks and other important factors that could materially impact our plans, including risks which are not solely within our control. See Part I, Item 1A. “Risk Factors” of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, filed with the SEC on March 12, 2025, as updated by Part II, Item 1A. “Risk Factors” of this Quarterly Report on Form 10-Q.

 

 

NPC is characterized by an inability of the body to transport cholesterol and lipids inside of cells. Symptoms of NPC include a progressive impairment of mobility, cognition, speech, and swallowing, often culminating in premature death. The incidence of NPC is estimated to be one in 100,000 to 130,000 live births. We estimate that there are approximately 1,800 individuals with NPC in the U.S. and Europe combined, of which approximately 900 are in the U.S. and 1,100 are in the EU, where there is a mature market with an approved treatment available for NPC. Of these, approximately 300 to 350 people have been diagnosed in the U.S. However, diagnostic challenges may affect the number of potential patients, and we believe that the availability of treatment options in the U.S. could increase awareness of the disease and assist in more accurately identifying patients. 

 

On September 20, 2024, the FDA approved the NDA for MIPLYFFA, an orally-delivered treatment, in combination with miglustat, for NPC, which is an ultra-rare and progressive neurodegenerative disease. MIPLYFFA, the first FDA-approved treatment for NPC, is indicated for use in combination with miglustat for the treatment of neurological manifestations of NPC in adult and pediatric patients two years of age and older. In addition, we received a transferable rare pediatric disease PRV in conjunction with the approval. On April 1, 2025, we completed the previously disclosed sale of the PRV (“Asset Sale”). The Asset Sale was completed pursuant to the terms of an asset purchase agreement, dated February 26, 2025 (the “PRV Transfer Agreement”). Pursuant to the PRV Transfer Agreement, the Company received gross proceeds of $150.0 million from the buyer upon the closing of the Asset Sale.

 

Effective therapies to treat NPC are desperately needed, and, for this reason, MIPLYFFA is currently being made available to NPC patients in France, Germany, and other EU member states under various EAPs. MIPLYFFA has also been granted orphan medical product designation for the treatment of NPC by the European Commission. As of March 31, 2025, there were a total of 122 enrollments to receive MIPLYFFA, which included conversion of all active participants in our U.S. EAP, which we expect to close by the end of the second quarter of 2025. Our commercial plans will focus on continuing to raise awareness among people who are living with NPC that are diagnosed and untreated, or undiagnosed. For MIPLYFFA, an enrollment is a prescription submitted to our specialty pharmacy, initiating the benefits investigation process to determine reimbursement and can lead to a 30-day paid dispense of MIPLYFFA.

 

Soon after approval of MIPLYFFA, the FDA approved a second therapy for NPC, AQNEURSA, which is approved for the treatment of neurological manifestations of NPC in adults and pediatric patients weighing ≥15 kg and is marketed by IntraBio, Inc.

 

To commercialize both of our commercial products, MIPLYFFA and OLPRUVA, in the U.S., we have built, or are making arrangements with third parties to perform, marketing, sales, medical affairs, distribution, managerial and other non-technical capabilities. 

 

Zevra holds global rights to develop and commercialize MIPLYFFA. We intend to seek regulatory approval for MIPLYFFA in the European Union (“EU”), and we are currently evaluating the potential to commercialize outside of the U.S. and/or to seek additional regulatory approvals to support future global commercialization opportunities. Our focus is currently on preparing for submission of a Marketing Authorisation Application, or MAA, in Europe in the second half of 2025.

 

	●	Demonstrated halting of disease progression. MIPLYFFA in combination with miglustat has demonstrated a halting of progression of the disease through 12 months of treatment.
	●	Ease of flexible administration as an oral treatment. MIPLYFFA is administered as an oral capsule that can be swallowed whole, opened and contents mixed with foods or liquids, or delivered through a feeding tube.
	●	Extensive clinical experience with favorable safety data. There have been no safety findings of concern with more than 600 patients treated in various clinical trials and through our EAPs.
	●	Advantageous regulatory designations. MIPLYFFA has been granted orphan medical product designation for the treatment of NPC by the European Commission. On April 1, 2025, we completed the sale of the PRV, which we received  upon approval of MIPLYFFA.

 

OLPRUVA

 

OLPRUVA (sodium phenylbutyrate) for oral suspension is approved in the U.S. as adjunctive therapy to standard of care, which includes dietary management, for the chronic management of UCDs involving deficiencies of carbamylphosphate synthetase (CPS), ornithine transcarbamylase (OTC), or argininosuccinic acid synthetase (AS). OLPRUVA for oral suspension is a proprietary and novel formulation of sodium phenylbutyrate powder, packaged in pre-measured single-dose envelopes, that has shown bioequivalence to existing sodium phenylbutyrate powder but with a pH-sensitive polymer coating that is designed to minimize dissolution of the coating for up to five (5) minutes after preparation.

 

UCDs are a group of rare genetic disorders that can cause harmful ammonia to build up in the blood, potentially resulting in brain damage and neurocognitive impairments, if ammonia levels are not controlled. Any increase in ammonia over time is serious. Therefore, it is important to adhere to any dietary protein restrictions and have alternative medication options to help control ammonia levels. Approximately 1 in 100,000 people have UCD, and there are an estimated 800 patients who are actively treated with nitrogen scavenging therapy in the U.S. While there are therapies currently approved for the treatment of UCDs - specifically RAVICTI, marketed by Amgen, Inc. (formerly Horizon Therapeutics) and PHEBURANE, marketed by Medunik USA - there remain unmet needs for this community of patients. OLPRUVA offers benefits over other UCD treatments by eliminating issues with palatability, offering improved portability with its single-dose envelopes, and it comes in a dosage personalized to the patient based on weight.

 

During the quarter ended December 31, 2023, we began generating revenue from the sale of OLPRUVA in the U.S. Zevra has a partnership with Relief Therapeutics, who has rights to commercialize OLPRUVA in various EU countries, if approved. In addition, Zevra was obligated to pay royalties of 10% of U.S. net sales up to a maximum of $45.0 million, plus specified regulatory milestones, for total payments to Relief of up to $56.5 million. On April 10, 2025, the rights to this royalty were sold to Soleus Capital Management L.P. 

 

During the first half of 2024, we initiated the commercial launch of OLPRUVA in the U.S. We have focused our initial efforts on the approximately 40 metabolic treatment centers of excellence (“COE”) across the United States, which treat the majority of UCD patients, to build awareness with physicians regarding the benefits of OLPRUVA. In the months since launch, our team has been able to engage with prescribers in more than 90% of these COEs. We have seen meaningful growth in reimbursement coverage, which was approximately 55% of U.S. covered lives at the time of acquisition, to now approximately 78%. In the third quarter of 2024, Zevra made a data-driven shift in our OLPRUVA commercial strategy to target specific patient segments that will receive the greatest benefit from OLPRUVA and face fewer reimbursement hurdles. To support this refinement in strategy, we focused our resources and promotional efforts in the third quarter to drive patient identification and to improve pull-through with payors. Specifically, we are targeting patients seeking greater lifestyle independence who could benefit from the “ammonia control on the go” that OLPRUVA offers.

 

OLPRUVA summary:

 

	●	OLPRUVA is available in the U.S for the treatment of certain types of UCDs. OLPRUVA is an adjunctive therapy for long-term management of adults and children weighing 20kg or greater with UCD from deficiencies of CPS, OTC, or AS.
	●	OLPRUVA is differentiated from currently available forms of phenylbutyrate. OLPRUVA is formulated to improve palatability while providing patients with a portable and discrete pre-measured dose.
	●	Zevra has assembled a team to support OLPRUVA and additional future commercial products. We have established an efficient commercial team which is designed to fully service the patients and prescribers within the rare disease indications we are pursuing.

 

 

Celiprolol

 

The Merger with Acer included the acquisition of celiprolol. We are advancing celiprolol as an investigational product candidate for the treatment of VEDS in patients with a confirmed type III collagen (COL3A1) mutation. Celiprolol is a selective adrenergic modulator (“SAM”) and, if we receive the first approval in the U.S. for celiprolol, we believe it would be deemed a new chemical entity (“NCE”) in the U.S. Celiprolol is currently approved in certain EU states for the treatment of hypertension and angina.

 

Ehlers-Danlos Syndrome is an inherited disorder caused by mutations in the genes responsible for the structure, production, or processing of collagen, an important component of the connective tissues in the human body, or proteins that interact with collagen. VEDS causes abnormal fragility in blood vessels, which can give rise to aneurysms, abnormal connections between blood vessels known as arteriovenous fistulas, arterial dissections, and spontaneous vascular ruptures, all of which can be potentially life-threatening. The incidence of VEDS is estimated to be one in 50,000 to 200,000 people. There are approximately 7,500 patients in the U.S.

 

Currently, there are no approved therapies anywhere in the world for VEDS. However, celiprolol, prescribed off label, has become the standard of care therapy for VEDS in some European countries. Medical intervention for VEDS focuses on surgery, symptomatic treatment, genetic counseling, and prophylactic measures, such as avoiding intense physical activity, scuba diving, and violent sports. Therefore, patients must adopt a “watch and wait” approach following any confirmed diagnosis. Unfortunately, many of these arterial events have high mortality associated with them, and thus, a pharmacologic intervention that reduces the rate of events would be clinically meaningful.

 

Celiprolol received orphan drug designation from the FDA for the treatment of VEDS in 2015. In October 2018, a new celiprolol NDA was submitted to the FDA by Acer based on data obtained from the BBEST trial and was subsequently accepted by the FDA in October 2018 with priority review status. Following FDA review, Acer received a CRL from the FDA stating that it will be necessary to conduct an adequate and well-controlled trial to determine whether celiprolol reduces the risk of clinical events in patients with VEDS. Subsequently, Acer appealed the FDA decision. While the FDA denied the appeal, it described possible paths forward toward approval. In a May 2021 Type B meeting with the FDA, Acer discussed the conduct of an U.S.-based prospective, randomized, double-blind, placebo-controlled, decentralized clinical trial in patients with COL3A1 positive VEDS, and sought the FDA’s opinion on various proposed design features of the study.

 

Based on FDA's feedback during the Type B meeting, we adopted a decentralized (virtual) event-based clinical trial design and use of an independent centralized adjudication committee with a primary endpoint based on clinical events associated with disease outcome. In April 2022, the FDA granted celiprolol Breakthrough Therapy designation in the U.S. for the treatment of patients with COL3A1-positive VEDS.

 

In July 2022, Acer initiated enrollment in a Phase 3 long-term event-driven clinical trial designed based on the discussions from the May 2021 Type B meeting with the FDA, also known as the DiSCOVER trial. The DiSCOVER trial intends to enroll 150 VEDS patients, with 100 patients receiving celiprolol and 50 patients receiving placebo. Recruitment in the Phase-3 trial was restarted mid-2024 after a brief hiatus and the trial has 32 enrolled participants as of March 31, 2025. We believe that celiprolol could address significant unmet needs as there are currently no approved treatments for VEDS in the U.S.

 

Celiprolol summary:

 

	●	Currently, no approved treatments for VEDS in the U.S. There are currently no approved treatments of VEDS in the U.S. and we believe that celiprolol, if approved, could be a significant innovation in the treatment of VEDS in the U.S. where current treatment options are focused primarily on surgical intervention.
	●	Unique pharmacological profile. Mechanism of action in VEDS patients is thought to be through vascular dilatation and smooth muscle relaxation, the effect of which is to reduce the mechanical stress on collagen fibers in the arterial wall, and thereby potentially less incidence of vascular ruptures.
	●	Evidence of efficacy in the EU and extensive clinical experience from multiple trials. Celiprolol has become the primary treatment for VEDS patients in several European countries. BBEST Clinical Trial data showed 76% reduction in risk of arterial events observed in COLA3A1+ subpopulation, with additional data from a long-term observational study in France.
	●	Regulatory designations. Celiprolol for VEDS would be considered an NCE in the U.S. and has been granted Orphan Drug designation and Breakthrough Therapy designation.
	●	Solid patent protection through 2038. Celiprolol is generally protected by U.S. patents that will expire, after utilizing all appropriate patent term adjustments but excluding possible term extensions, in 2038.

 

 

 

KP1077

 

KP1077 is being developed and evaluated for the treatment of IH and narcolepsy. IH is a rare neurological sleep disorder affecting approximately 37,000 patients in the United States. The cardinal feature of IH is excessive daytime sleepiness (“EDS”), characterized by daytime lapses into sleep, or an irrepressible need to sleep that persists even with adequate or prolonged nighttime sleep. Additionally, those with IH have extreme difficulty waking, otherwise known as “sleep inertia,” suffer from severe and debilitating brain fog, and may fall asleep unintentionally or at inappropriate times, also known as narcolepsy. These symptoms often further lead to reported memory problems, difficulty maintaining focus, and depression.

 

Narcolepsy is a rare, chronic, debilitating neurologic disorder of sleep-wake state instability that impacts up to 200,000 Americans and is primarily characterized by EDS and cataplexy (sudden loss of muscle tone while a person is awake) along with other manifestations of rapid eye movement, sleep dysregulation, which intrude into wakefulness. In most patients, narcolepsy is caused by the loss of hypocretin, a neuropeptide in the brain that supports sleep-wake state stability. Typical symptom onset occurs in adolescence or young adulthood, but it can take up to a decade to be properly diagnosed. Although there are several approved medications for narcolepsy, we believe a treatment option based on serdexmethylphenidate (“SDX”), our proprietary prodrug of d-methylphenidate (“d-MPH”), which has previously been classified as a Schedule IV controlled substance, may be beneficial.

 

There is currently only one approved product for the treatment of IH, XYWAV, developed by Jazz Pharmaceuticals. A second product, WAKIX, developed by Harmony Biosciences (“Harmony”), was originally approved for the treatment of EDS or cataplexy in adult patients with narcolepsy, but in October 2023, Harmony announced that the difference in outcome for EDS when comparing WAKIX and placebo in its Phase 3 trial with IH patients did not reach statistical significance. Prescribers also utilize narcolepsy medications and various stimulant products “off-label” to treat IH symptoms, with methylphenidate, a stimulant which has been classified by the DEA as a Schedule II controlled substance, being one of the most commonly used stimulants for treating IH. While each of these medications can help to address certain IH symptoms, there are also potential shortcomings, including dosing inconvenience, serious adverse events, such as elevated blood pressure and heart rate, and significant drug-to-drug interactions (“DDIs”), including with medications used to manage contraception and depression. In addition, patients have indicated that the effectiveness of their current medication was poor.

 

We reported final data for the Phase 1 proof-of-concept study of SDX in the first quarter of 2022. Increased wakefulness, alertness, hypervigilance, and insomnia effects were reported by study participants, which we believe suggests that SDX produced targeted pharmacodynamic effects that have the potential to benefit patients with IH and other sleep disorders. In November 2022, we announced that the FDA has granted the orphan drug designation to SDX for the treatment of IH.

 

KP1077 utilizes SDX, our prodrug of d-MPH, as its active pharmaceutical ingredient (“API”). During the first quarter of 2022, we initiated a Phase 1 clinical trial comparing the cardiovascular safety of SDX to immediate-release and long-acting formulations of RITALIN, a commonly prescribed central nervous system (“CNS”) stimulant. In September 2022, we announced topline data from our exploratory Phase 1 clinical trial, which showed the potential for higher dose formulations of SDX to be safe and well tolerated while avoiding the potential for greater cardiovascular safety risk compared to immediate-release and long-acting formulations of RITALIN.

 

Based on the data, in December 2022, we announced the initiation of a double-blind, placebo-controlled, randomized-withdrawal, dose-optimizing, multicenter Phase 2 clinical trial evaluating the efficacy and safety of KP1077 for the treatment of IH. The trial concluded in March 2024 and provided meaningful information of the optimal dose and dosing regimen to inform Phase 3 trial design.

 

Clinically meaningful improvements were observed across all studied endpoints. The exploratory endpoints of sleep inertia and brain fog performed in-line with expectations and were stable when compared across a variety of other endpoints. Symptom improvements in patients receiving KP1077 were similar after both once-per-day, and twice-per-day dosing.

 

KP1077 Summary:

 

	●	No drug-to-drug interactions observed to date. We have not observed drug-to-drug interactions in clinical drug-drug interaction studies.
	●	Potential for reduced abuse potential as a Schedule IV controlled substance. All other methylphenidate-based products have been designated as Schedule II controlled substances, which indicates stricter control over the prescribing and use of such products. KP1077 is based on SDX, which has been designated a Schedule IV controlled substance.
	●	No currently approved generic equivalent product. KP1077 contains SDX, our proprietary prodrug of d-methylphenidate, also known as the new chemical name, serdexmethylphenidate, by the U.S. Adopted Names Council of the American Medical Association, which means that there may be no generic equivalent product for KP1077 in most states, making drug-equivalent substitution potentially difficult at the pharmacy.
	●	Orphan drug designation. Because the size of the IH patient population is small, the FDA has granted KP1077 orphan drug designation for the treatment of IH. We believe KP1077 may potentially be eligible for fast-track and breakthrough therapy designation, which may provide various regulatory benefits for the development program.

 

 

AZSTARYS (Partnered product)

 

AZSTARYS contains d-MPH and our prodrug of d-MPH, SDX. On March 2, 2021, the FDA approved AZSTARYS as a once-daily treatment for attention deficit hyperactivity disorder (ADHD), in patients age six years and older. AZSTARYS is currently being marketed in the U.S. under our September 2019 collaboration and license agreement, or the AZSTARYS License Agreement, with Commave. Under the AZSTARYS License Agreement, we granted Commave an exclusive, worldwide license, to develop, manufacture, and commercialize AZSTARYS and any of our product candidates containing SDX and used to treat ADHD or any other CNS disease. In July 2020, we entered into the consulting agreement with Corium, Inc. (“Corium”), under which Corium and Commave, respectively, engaged us to guide the product development and regulatory activities for certain current and potential future products in their portfolio, as well as continue supporting preparation for the potential commercial launch of AZSTARYS.

 

Commave has tasked Corium, another affiliate of Gurnet Point Capital, L.P., to lead all commercialization activities for AZSTARYS in the U.S. Corium commercially launched AZSTARYS in the U.S. during the third quarter of 2021. In December 2021, Commave entered into a sublicense of commercialization rights for AZSTARYS in greater China to Shanghai Ark Biopharmaceutical Ltd.

 

Pursuant to the AZSTARYS License Agreement, Commave agreed to pay up to $63.0 million in milestone payments upon the occurrence of specified regulatory milestones related to AZSTARYS, including FDA approval and specified conditions with respect to the final approval label. In addition, Corium agreed to make additional payments upon the achievement of specified U.S. sales milestones of up to $420.0 million in the aggregate. Further, Commave will pay us quarterly, tiered royalty payments based on a percentage of net sales on a product-by-product basis. Corium also agreed to be responsible for and reimburse us for all of development, commercialization and regulatory expenses for any products or product candidates containing SDX, subject to certain limitations as set forth in the AZSTARYS License Agreement, including consultation fees to be paid to us for services provided to Corium in performing such activities.

 

In April 2021, we entered into the AZSTARYS Amendment (“AZSTARYS Amendment”). Pursuant to the AZSTARYS Amendment, we and Commave agreed to modify the compensation terms of the AZSTARYS License Agreement. Commave paid us $10.0 million in connection with the execution of the AZSTARYS Amendment following the FDA approval of AZSTARYS in the United States. Corium also paid us $10.0 million following the SDX scheduling determination by the DEA, which occurred on May 7, 2021. In addition, the AZSTARYS Amendment increased the total remaining future regulatory and sales milestone payments related to AZSTARYS up to an aggregate of $590.0 million. The AZSTARYS License Agreement will continue on a product-by-product basis (i) until expiration of the royalty term for the applicable product candidate in the United States and (ii) perpetually for all other countries.

 

In May 2021, we announced that SDX, our proprietary prodrug of d-MPH and the primary API in AZSTARYS, was classified as a Schedule IV controlled substance by the DEA. AZSTARYS is classified as a Schedule II controlled substance as its formulation includes a 70:30 mixture of SDX (Schedule IV) and d-MPH (Schedule II), respectively.

 

 

Other Third-Party Agreements

Net Loss

 

Revenue

 

Revenue for the three months ended March 31, 2025, was $20.4 million, compared to revenue of $3.4 million for the three months ended March 31, 2024 an increase of $17.0 million. The increase was primarily due to an increase in product sales of MIPLYFFA of $17.1 million.

 

 

Research and development

 

Research and development expenses decreased by $9.0 million, from $12.3 million for the three months ended March 31, 2024, to $3.3 million for the three months ended March 31, 2025. This decrease was primarily driven by a decrease in spending for the ongoing Phase 2 clinical study in KP1077 and a decrease in personnel-related costs.

 

Selling, general and administrative

 

Selling, general and administrative expenses increased by $9.6 million, from $9.9 million for the three months ended March 31, 2024, to $19.5 million for the three months ended March 31, 2025. The period-over-period increase was primarily related to an increase in personnel-related costs, professional fees, and other expenses as we continue to build our commercial organization. 

 

Other income 

 

Other income for the three months ended March 31, 2025, was $3.4 million compared to other income of $3.8 million for the three months ended March 31, 2024. This change was primarily attributable to an increase in interest expense of $1.2 million and a decrease in interest and other income of $0.4 million, partially offset by an increase in the fair value adjustment related to warrant and CVR liability of $1.2 million.

Liquidity and Capital Resources

 

Sources of Liquidity

 

Through March 31, 2025, we have funded our research and development and operating activities primarily through the issuance of debt and equity and from product sales of MIPLYFFA and OLPRUVA, reimbursements received under the French AC, royalties or net sales milestone payments generated under the AZSTARYS License Agreement, and consulting agreements. As of March 31, 2025, we had cash, cash equivalents and investments of $68.7 million.

 

On February 26, 2025, we entered into the PRV Transfer Agreement, pursuant to which we agreed to sell the PRV to the buyer, subject to customary closing conditions. Pursuant to the PRV Transfer Agreement, the buyer agreed to pay the Company $150.0 million, payable in cash, upon the closing of the sale. On April 1, 2025, the asset sale was consummated, resulting in net proceeds of $148.3 million to the Company.

 

We have had recurring negative net operating cash flows throughout our operating history, and we cannot guarantee or predict when we may begin to consistently generate positive net cash flows from operations, or if at all. We expect that our sources of revenue will be from product sales of MIPLYFFA and OLPRUVA, reimbursements received under the French AC, royalties or net sales milestone payments generated under the AZSTARYS License Agreement, consulting agreements, and any other future arrangements related to one or more of our products or product candidates.

 

Adequate additional financing may not be available to us on acceptable terms, or at all. To the extent that we raise additional capital through the sale of equity or debt, the terms of these securities may restrict our ability to operate. If we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may be required to relinquish valuable rights. If we are unable to raise capital when needed or on attractive terms, we could be forced to delay, reduce or altogether cease our research and development programs or future commercialization efforts.

 

 

 

Registration Statements on Form S-3

 

In connection with the Merger, we and Nantahala Capital Management, LLC (“Nantahala”) concurrently entered into a registration rights agreement, pursuant to which we agreed to file a resale registration statement with respect to the resale of our common stock issuable to Nantahala. On February 5, 2024, we filed a registration statement on Form S-3 (File No. 333-276856) registering an aggregate of 2,269,721 shares of our common stock. On April 5, 2024, we filed an amendment to such registration statement, which was declared effective on April 8, 2024. 

 

On June 4, 2024, we filed a registration statement on Form S-3 (File No. 333-279941) (the “June 2024 Registration Statement”) under which we sell securities, including as may be issuable upon conversion, redemption, repurchase, exchange or exercise of securities, in one or more offerings up to a total aggregate offering price of $350.0 million, $75.0 million of which was allocated to the sale of the shares of common stock issuable under the 2024 ATM Agreement. The registration statement was declared effective on June 13, 2024.

 

August 2024 Offering

 

On August 8, 2024, we entered into an underwriting agreement (the “Underwriting Agreement”) with Cantor Fitzgerald & Co. and William Blair & Company, L.L.C., as representatives of the several underwriters named therein (collectively, the “Underwriters”), in connection with the offering, issuance and sale by us of 9,230,770 shares of our common stock at a public offering price of $6.50 per share, pursuant to the June 2024 Registration Statement and a related prospectus supplement dated August 8, 2024 filed with the SEC (the “August 2024 Offering”). Under the terms of the Underwriting Agreement, we also granted the Underwriters an option exercisable for 30 days to purchase up to an additional 1,384,615 shares of our common stock at the public offering price, less underwriting discounts and commissions, which the Underwriters exercised in full on August 9, 2024. The August 2024 Offering closed on August 12, 2024. Total shares issued were 10,615,385. Net proceeds from the offering were approximately $64.5 million, after deducting underwriting discounts and commissions and estimated offering expenses payable by us. We intend to use the net proceeds of the offering to support the commercial launch activities for MIPLYFFA, continued commercial support for OLPRUVA and the continued development of celiprolol through potential NDA filings and other general corporate purposes.

 

Entry into 2024 ATM Agreement

 

On July 12, 2024, we entered into an equity distribution agreement (the “2024 ATM Agreement”) with Citizens JMP Securities LLC (“Citizens JMP”) under which we may offer and sell, from time to time at our sole discretion, shares of our common stock having an aggregate offering price of up to $75.0 million through Citizens JMP as its sales agent. The issuance and sale, if any, of common stock by us under the 2024 ATM Agreement will be made pursuant to the June 2024 Registration Statement, the accompanying prospectus, and the related prospectus supplement dated July 12, 2024. Citizens JMP may sell the common stock by any method permitted by law deemed to be an “at the market offering” as defined in Rule 415 of the Securities Act. Citizens JMP will use commercially reasonable efforts to sell the common stock from time to time, based upon instructions from us (including any price, time or size limits or other customary parameters or conditions we may impose). We will pay Citizens JMP a commission equal to 3.0% in the aggregate of the gross sales proceeds of any common stock sold through Citizens JMP under the 2024 ATM Agreement. As of March 31, 2025, no shares have been issued or sold under the 2024 ATM Agreement.

 

Merger

 

The assets acquired and liabilities assumed were recorded based on their acquisition date fair values. Consideration for the Merger was $72.6 million and consists of (i) approximately 2.96 million shares of Zevra common stock valued at $12.8 million, (ii) the Bridge Loan advances of $17.8 million, (iii) $12.0 million in cash paid to Nantahala; (iv) 2.27 million shares of Zevra Common Stock issued to Nantahala valued at $11.5 million based on the VWAP of shares of Zevra Common Stock during the 20 consecutive trading days ending on the trading date prior to August 30, 2023; (v) a secured promissory note payable by Zevra to Nantahala in the original principal amount of $5.0 million, (vi) $8.5 million in the estimated fair value of contingent consideration related to the CVRs, (vii) approximately 0.9 million shares of Zevra Common Stock issued to a former holder of Acer warrants valued at $4.0 million based on Zevra's common stock price on the Effective Date and (viii) $1.0 million in notes payable paid by the Company on Acer's behalf. In addition, effective as of immediately prior to the Effective Time, all of the outstanding and unexercised Acer stock options were automatically cancelled and ceased to exist without any cash or other consideration being paid or provided in respect thereof. 

 

In connection with the closing of the Merger on November 17, 2023, each share of common stock of Acer was converted into the right to receive (i) 0.1210 fully paid and non-assessable shares of common stock of Zevra, par value $0.0001 per share, and (ii) one non-transferable CVR to be issued by Zevra, which will represent the right to receive one or more contingent payments up to an additional $76.0 million upon the achievement, if any, of certain commercial and regulatory milestones for Acer’s OLPRUVA and celiprolol products within specified time periods. Certain additional cash payments are also possible pursuant to the CVRs with respect to milestones involving Acer’s early-stage program ACER-2820 (emetine).

 

 

Stockholders Agreement

 

In connection with the Merger, a certain stockholder of Acer entered into, and Acer agreed to use its reasonable best efforts to cause certain other stockholders to enter into joinders to, a stockholders agreement with Zevra (the “Stockholders Agreement”). Pursuant to the Stockholders Agreement, the stockholders party thereto agreed to, or would agree to, among other things, vote all of their shares in Zevra that they own in favor of each nominee included in the Zevra board of director’s slate of nominees for each election of directors and in favor of each matter approved by the Zevra board of directors and submitted to stockholders of Zevra for the approval of stockholders following the closing of the Merger and until the second anniversary of the Closing Date of the Merger (the “Trigger Date”). In addition, the stockholders party to the Stockholders Agreement will be subject to customary standstill provisions, subject to certain exceptions, until the Trigger Date.

 

Term Loans

 

 

 

 

The Credit Agreement contains customary affirmative and negative covenants by us, which among other things, will require us to provide certain financial reports to the Lenders, meet certain minimum net product sales amounts, and limit our ability to incur or guarantee additional indebtedness, engage in certain transactions, and effect a consolidation or merger without consent. In addition, as long as the line of credit remains active, we must maintain a minimum cash balance of $20.0 million to ensure that we can meet our immediate capital needs. Our obligations under the Credit Agreement may be accelerated upon customary events of default, including non-payment of principal, interest, fees and other amounts, covenant defaults, insolvency, material judgments, or inaccuracy of representations and warranties. The Term Loans are secured by a first priority perfected lien on, and security interest in, substantially all of our current and future assets. The proceeds of the Term Loans were used to refinance certain of our previously existing indebtedness. We will use the remaining proceeds to pay fees and expenses related to the debt financing and fund the development and commercialization of MIPLYFFA and OLPRUVA.

 

 

Cash Flows

 

The following table summarizes our cash flows for the three months ended March 31, 2025, and 2024 (in thousands):

 

		Three months ended March 31,
		2025				2024
Net cash used in operating activities		$	(8,222	)		$	(16,165	)
Net cash provided by investing activities			10,542				14,793

Effect of exchange rate changes on cash and cash equivalents			(372	)			(45	)
Net increase (decrease) in cash and cash equivalents		$	3,555			$	(200	)

 

Operating Activities

 

For the three months ended March 31, 2025, net cash used in operating activities of $8.2 million consisted of a net loss of $3.1 million and changes in working capital of $6.8 million, partially offset by $1.7 million in adjustments for non-cash items. Net loss was primarily attributable to our spending on research and development programs and operating costs; partially offset by revenue received from product sales of MIPLYFFA and OLPRUVA, royalties generated under the AZSTARYS License Agreement, and reimbursements received under the French AC. The changes in working capital consisted of $7.3 million related to a change in accounts payable and accrued expenses, a $0.2 million change in inventories, $0.2 million related to a change in operating lease liabilities, $2.1 million related to a change in accounts and other receivables, partially offset by an increase of $0.6 million related to a change in other liabilities, $0.3 million in prepaids and other assets, $0.2 million related to a change in operating lease right-of-use assets, and $1.9 million related to a change in discount and rebate liabilities. The adjustments for non-cash items primarily consisted of stock-based compensation expense of $3.1 million, interest expense of $0.7 million, and $2.8 million related to depreciation, amortization and other items, partially offset by a change in the fair value of warrant and CVR liability of $4.9 million. 

 

For the three months ended March 31, 2024, net cash used in operating activities of $16.2 million consisted of a net loss of $16.6 million and $0.2 million in changes in working capital; partially offset by $0.6 million in adjustments for non-cash items. Net loss was primarily attributable to our spending on research and development programs and operating costs; partially offset by revenue received from product sales of OLPRUVA, reimbursements received under the French AC, and royalties or net sales milestone payments generated under the AZSTARYS License Agreement. The changes in working capital consisted of $7.4 million related to a change in accounts payable and accrued expenses, $0.1 million related to a change in operating lease liabilities, $2.6 million related to a change in inventories, and $0.3 million related to a change in other liabilities; partially offset by $9.1 million related to a change in accounts and other receivables, $1.0 million related to a change in discount and rebate liabilities, and $0.1 million related to a change in operating lease right-of-use assets. The adjustments for non-cash items primarily consisted of stock-based compensation expense of $2.1 million, interest expense of $0.2 million, and $1.9 million related to depreciation, amortization and other items; partially offset by a change in the fair value of warrant and CVR liability of $3.6 million. 

 

Investing Activities

 

For the three months ended March 31, 2025, net cash provided by investing activities was $10.5 million, which was primarily attributable to maturities of investments of $18.0 million, partially offset by $7.4 million in purchases of investments.

 

For the three months ended March 31, 2024, net cash provided by investing activities was $14.8 million, which was primarily attributable to maturities of investments.

 

Financing Activities

 

For the three months ended March 31, 2025, net cash provided by financing activities was $1.6 million, which was primarily attributable to proceeds from the issuance of stock of $2.0 million partially offset by payments of principal on insurance financing arrangements of $0.4 million.

 

For the three months ended March 31, 2024, net cash provided by financing activities was $1.2 million, which was primarily attributable to proceeds from the issuance of stock.

 

 

Future Funding Requirements

 

We believe our available cash and cash equivalents, together with our ability to generate operating cash flow and our access to short-term and long-term borrowings, are sufficient to fund our existing and planned capital requirements for at least the next twelve months and the foreseeable future.

 

We maintain the majority of our cash and cash equivalents in accounts with major U.S. and multi-national financial institutions, and our deposits at these institutions exceed insured limits. Market conditions can impact the viability of these institutions. In the event of a failure of any of the financial institutions where we maintain our cash and cash equivalents, there can be no assurance that we would be able to access uninsured funds in a timely manner or at all. Any inability to access or delay in accessing these funds could adversely affect our business and financial position.

 

Potential near-term sources of additional funding include:

 

	●	any royalties or net sales milestone payments generated under the AZSTARYS License Agreement;
	●	any reimbursements received for arimoclomol under the French AC;
	●	any product sales of OLPRUVA; and
	●	any product sales of MIPLYFFA.

 

We cannot guarantee that we will be able to generate sufficient proceeds from any of these potential sources to fund our operating expenses. We anticipate that our expenses will fluctuate substantially as we:

 

	●	continue our ongoing clinical trials and our product development activities for our pipeline of product candidates;
	●	seek regulatory approvals for any product candidates that successfully complete clinical trials;
	●	continue research and development and clinical trials of our product candidates;
	●	seek to discover and develop additional product candidates either internally or in partnership with other pharmaceutical companies;
	●	adapt our regulatory compliance efforts to incorporate requirements applicable to marketed products;
	●	maintain, expand and protect our intellectual property portfolio; and
	●	incur additional legal, accounting and other expenses in operating as a public company.

 

To date, we have generated revenue from product sales of MIPLYFFA and OLPRUVA, reimbursements received under the French AC, royalties or net sales milestone payments generated under the AZSTARYS License Agreement, and consulting agreements. We expect that, for the foreseeable future, our sources of revenues will be from product sales of MIPLYFFA and OLPRUVA, reimbursements received under the French AC, royalties or net sales milestone payments generated under the AZSTARYS License Agreement, consulting agreements, and any other future arrangements related to one or more of our products or product candidates. We cannot guarantee that our current commercialization strategies, or any strategy we adopt in the future, will be successful. For instance, we received milestone payments under the AZSTARYS License Agreement, but we cannot guarantee that we will earn any additional milestone or royalty payments under this agreement in the future. We also cannot guarantee that we will continue to receive reimbursements under the French AC or successfully commercialize MIPLYFFA or OLPRUVA. We also expect to continue to incur significant additional costs associated with operating as a public company.

 

We have based our estimates of our cash needs and cash runway on assumptions that may prove to be wrong, and we may use our available capital resources sooner than we currently expect. In addition, we cannot guarantee that we will be able to generate sufficient proceeds from product sales of MIPLYFFA and OLPRUVA, reimbursements received under the French AC, royalties or net sales milestone payments generated under the AZSTARYS License Agreement, consulting agreements, or other funding transactions to fund our operating expenses. To meet any additional cash requirements, we may seek to sell additional equity or convertible securities that may result in dilution to our stockholders, issue additional debt or seek other third-party funding, including potential strategic transactions, such as licensing or collaboration arrangements. Because of the numerous risks and uncertainties associated with the development and commercialization of product candidates and products, we are unable to estimate the amounts of increased capital outlays and operating expenditures necessary to complete the commercialization and development of our partnered product or product candidates, should they obtain regulatory approval.

 

Adequate additional financing may not be available to us on acceptable terms, or at all. To the extent that we raise additional capital through the sale of equity or debt, the terms of these securities may restrict our ability to operate. If we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may be required to relinquish valuable rights. If we are unable to raise capital when needed or on attractive terms, we could be forced to delay, reduce or altogether cease our research and development programs and/or commercialization efforts.

 

 

Critical Accounting Estimates

 

This management’s discussion and analysis of our financial condition and results of operations is based on our unaudited condensed consolidated financial statements, which we have prepared in accordance with accounting principles generally accepted in the United States. The preparation of our unaudited condensed consolidated financial statements requires us to make estimates that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of our unaudited condensed consolidated financial statements, as well as the reported revenues and expenses during the reported periods. We evaluate these estimates on an ongoing basis. We base our estimates on historical experience and on various other factors that we believe are reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

 

Our critical accounting policies have not changed materially from those described in Part II, Item 7 – Management’s Discussion and Analysis of Financial Condition and Results of Operations of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, filed with the SEC on March 12, 2025.

 

ITEM 3.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

 

Not applicable.

 

ITEM 4.

CONTROLS AND PROCEDURES

 

Limitations on Effectiveness of Controls and Procedures

 

In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.

 

Evaluation of Disclosure Controls and Procedures

 

Our management, with the participation of our chief executive officer and our 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) as of March 31, 2025. Based on the evaluation of our disclosure controls and procedures as of March 31, 2025, our chief executive officer and our chief financial officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.

 

Changes in Internal Control Over Financial Reporting

 

There was no change in our internal control over financial reporting identified in connection with the evaluation required by Rules 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during our fiscal quarter ended March 31, 2025, that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

 

 

PART II

OTHER INFORMATION

 

ITEM 1.

LEGAL PROCEEDINGS

 

From time to time, we may be involved in routine legal proceedings, as well as demands, claims and threatened litigation, which arise in the normal course of our business. In connection with the AZSTARYS License Agreement with Commave, a dispute has arisen with Commave concerning the interpretation of certain provisions under the AZSTARYS License Agreement. On September 4, 2024, Commave filed a complaint against Zevra in the Court of Chancery of the State of Delaware (Case No. 2024-0920-LWW) alleging breach of contract and seeking injunctive relief, specific performance, declaratory relief, and damages regarding the parties' respective rights and obligations under the Agreement.

 

On February 12, 2025, our motion to dismiss was denied and the case is now in the discovery phase. We strongly disagree with Commave's allegations and believe this lawsuit is without merit.

 

The litigation is in its early stages. While we intend to vigorously defend against Commave's claims, the outcome of this matter is inherently uncertain. We cannot predict with certainty the timing or ultimate outcome of this litigation or its potential impact on our business, financial condition, or results of operations. At this time, we have not recorded any accrual for contingent liability associated with this matter.

 

The AZSTARYS License Agreement remains in effect during this litigation, and both parties continue to perform their respective obligations thereunder. However, there can be no assurance that this dispute will not have an adverse impact on our relationship with Commave or on Zevra’s business.

 

We will continue to monitor developments in this matter and will assess the potential impact on our financial statements in future periods. We expect to incur significant legal expenses in connection with this litigation, which may materially affect our results of operations in future periods.

 

Other than as disclosed herein, we believe there is no litigation pending that would reasonably be expected to, individually or in the aggregate, have a material adverse effect on our results of operations or financial condition.

 

ITEM 1A.

RISK FACTORS

 

In addition to the other information set forth in this Quarterly Report on Form 10-Q, you should carefully consider all the risk factors and uncertainties described in Part I, Item 1A. “Risk Factors” of our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, filed with the SEC on March 12, 2025, before investing in our common stock. Other than as described below, there have been no material changes to the risk factors described in that report. If any such risks materialize, our business, financial condition and results of operations could be seriously harmed. This Quarterly Report on Form 10-Q also contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in the forward-looking statements because of the risk factors in our Annual Report on Form 10-K and below, and the other factors described in in this Quarterly Report on Form 10-Q.

 

Significant political, trade, regulatory developments, and other circumstances beyond our control could delay, prevent or impair our development or commercialization efforts.

 

Trade policies, geopolitical disputes and other international conflicts can result in tariffs, sanctions and other measures that restrict international trade, and can materially adversely affect our business, particularly if these measures affect regions where manufacturing and product development activities take place or raw materials are sourced. For example, the U.S. government has recently imposed tariffs on certain foreign goods, and some foreign governments have threatened or instituted retaliatory tariffs on certain U.S. goods and have indicated a willingness to impose additional tariffs on U.S. products, which could increase the cost of goods needed to commercialize our products and continue development of our product candidates. The extent and duration of any tariffs and the resulting impact on general economic conditions and on our business are uncertain and depend on various factors, such as negotiations between the United States and other countries, the response of such countries, and exemptions or exclusions that may be granted. Countries may also adopt other measures, such as controls on imports or exports of goods, technology or data, that could adversely impact supply chains. As these tensions continue to rise, more targeted approaches on certain products, industries or companies could significantly impact our development and commercialization efforts. Further, such actions by the U.S. could result in other retaliatory actions by those countries which could impact our ability to profitably commercialize our products in those jurisdictions. As a result, our business, operations, and financial condition could be materially harmed.

 

Our future success depends on our ability to retain key executives and to attract, retain and motivate qualified personnel.

 

We are highly dependent on the management, research and development, clinical, financial and business development expertise of our senior leadership team, as well as the other members of our scientific and clinical teams. Although we have employment agreements with each of our executive officers, these agreements do not obligate them to continue working for our company and they may terminate their employment with us at any time. Our future performance will depend, in part, the successful transitions and integration of new senior level executives into their roles and the continuity of leadership among the larger workforce. If we do not successfully manage executive transitions, it could be viewed negatively by our customers, employees, investors, and other third-party partners, and could have an adverse impact on our business and results of operations.

 

Changes in U.S. immigration policies could impact our ability to attract and retain international talent. As a company with employees outside the U.S., restrictions or delays in immigration processing, visa issuance, or changes to work authorization requirements could hinder our ability to hire or retain qualified personnel needed for our operations. These challenges may increase our recruitment costs or delay key projects that require specialized expertise.

 

 

Recruiting and retaining qualified scientific and clinical personnel and, if we progress the development of our product candidate pipeline toward scaling up for commercialization, manufacturing and sales and marketing personnel, will also be critical to our success. The loss of the services of our executive officers or other key employees could impede the achievement of our research, development and commercialization objectives and seriously harm our ability to successfully implement our business strategy. Furthermore, replacing executive officers and key employees may be difficult and may take an extended period of time because of the limited number of individuals in our industry with the breadth of skills and experience required to successfully develop, gain regulatory approval of and commercialize our prodrug product candidates. Competition to hire from this limited pool is intense, and we may be unable to hire, train, retain or motivate these key personnel on acceptable terms given the competition among numerous pharmaceutical and biotechnology companies for similar personnel. We also experience competition for the hiring of scientific and clinical personnel from universities and research institutions. In addition, we rely on consultants and advisors, including scientific and clinical advisors, to assist us in formulating our research and development and commercialization strategy. Our consultants and advisors may have commitments under consulting or advisory contracts with other entities that may limit their availability to us. If we are unable to continue to attract and retain high quality personnel, our ability to pursue our growth strategy will be limited.
