Strong balance sheet with cash, cash equivalents and investments of $102.9 million which extends the cash runway into 2026

Celebration, FL – March 7, 2023 – Zevra Therapeutics, Inc. (NasdaqGS: ZVRA) (“Zevra,” or “the Company,” formerly “KemPharm, Inc.”), a rare disease therapeutics company, today reported its financial results for the fourth quarter and year ended December 31, 2022. 

“Zevra is a company transformed, with a new strategic purpose to deliver novel therapeutics to patients with rare diseases,” said Richard W. Pascoe, Chief Executive Officer of Zevra Therapeutics.  “The Company is guided by a world-class leadership team and board of directors, and we are in a strong position to execute on multiple anticipated milestones during 2023 that should provide a springboard for continued value creation. The Company’s future is more promising than at any time in our history as we are primed to advance arimoclomol, our NDA-stage investigational product candidate for Niemann-Pick disease Type C (“NPC”), and KP1077, our lead clinical candidate for treatment for idiopathic hypersomnia (IH), towards key regulatory and data events during the year. As we move Zevra forward, we will continue to leverage our legacy platform to target internally discovered rare disease product opportunities and to extend exclusivity of our pipeline assets through life cycle management.” 

Mr. Pascoe continued, “We believe the numerous clinical, regulatory and revenue milestone opportunities anticipated for 2023 and beyond will position Zevra for continued growth as we focus on bringing much-needed therapies to patients with rare diseases.  Our strategic and pipeline development efforts are supported by a strong financial foundation with $102.9 million in cash, cash equivalents, and investments as of December 31, 2022, and with a growing revenue stream from AZSTARYS® royalties and anticipated milestone payments, and ongoing revenue from the arimoclomol early access program in France. Based on our current operating forecast, we expect available capital will allow us to pursue our development plans and extend our cash runway into 2026, positioning us to build a fully integrated commercial company.”

Overview of Fourth Quarter (Q4) and Full-Year (FY) 2022 Financial Results: 

Net revenue for Q4 2022 was $2.3 million, as compared to Q4 2021 net revenue of $2.6 million. Q4 2022 net revenue was primarily driven by ongoing reimbursements received from the French early access program for arimoclomol, AZSTARYS® royalty revenues and consulting fees.

Research and development (R&D) expenses were $6.4 million for Q4 2022, as compared to $2.8 million in Q4 2021. The period-over-period increase was primarily driven by the KP1077 clinical development program and the addition of the arimoclomol program in Q2 2022. 

General and administrative (G&A) expenses were $5.1 million for Q4 2022, as compared to $2.6 million in Q4 2021. The period-over-period increase was primarily related to the arimoclomol acquisition, which led to an increase in compensation costs, including non-cash stock-based compensation expense, as well as increased professional fees and depreciation and amortization expenses beginning in Q2 2022. 

Net loss attributable to common stockholders for Q4 2022 was ($9.0) million, or ($0.26) per basic and diluted share, compared to a net loss attributable to common stockholders of ($2.7) million, or ($0.08) per basic and diluted share for the same period in 2021. Net loss for Q4 2022 was driven primarily by R&D expenses of $6.4 million and G&A expenses of $5.1 million, partially offset by net revenue of $2.3 million and other income of $0.2 million.  

Net revenue for FY 2022 was $10.5 million, as compared to FY 2021 net revenue of $28.7 million.  The period-over-period decrease was primarily attributed to the non-recurrence of the one-time regulatory milestone payments totaling $20 million for the approval of AZSTARYS and the subsequent scheduling of SDX by the U.S. Drug Enforcement Agency as a C-IV scheduled controlled substance. 

For FY 2022, R&D expenses were $19.6 million, as compared to $10.2 million in FY 2021.  The period-over-period increase was primarily driven by increased investments in the KP1077 clinical development program, and the addition of the arimoclomol program. 

G&A expenses were $15.3 million for FY 2022, as compared to $8.7 million in FY 2021.  The period-over-period increase was primarily driven by the acquisition of arimoclomol in Q2 2022. 

Net loss attributable to common stockholders for FY 2022 was ($41.5) million, or ($1.20) per basic and diluted share, compared to a net loss attributable to common stockholders of ($62.9) million, or ($2.11) per basic and diluted share in 2021.  Net loss for FY 2022 was driven primarily by R&D expenses of $19.6 million, G&A expenses of $15.3 million, and a one-time non-cash charge of $17.7 million for acquired in-process R&D related to the arimoclomol asset acquisition in Q2 2022, partially offset by net revenues of $10.5 million.  Non-GAAP FY 2022 net loss, excluding the one-time non-cash charge of $17.7M, was ($23.9M), or ($0.69) per basic and diluted share.

As of December 31, 2022, total cash, cash equivalents, and investments were $102.9 million, which was a decrease of $4.5 million compared to $107.4 million as of September 30, 2022.  The decrease was driven, in part, by increased third-party R&D costs related to the KP1077 clinical trial program, the arimoclomol program, and investment of working capital related to the collection of accounts receivable due from French EAP reimbursements. 

Based on the Company’s current operating forecast, which includes approximately $2.0M in net revenue per quarter from the French early access program reimbursements, existing cash, cash equivalents, and investments are expected to be sufficient to continue operations into 2026, including activities required to submit an NDA for KP1077 and its potential PDUFA date, and to fund commercial preparation for the potential launch of arimoclomol in the U.S., if approved. 

As of December 31, 2022, the total shares of common stock outstanding was 34,540,304 shares, and the fully diluted common shares outstanding was 47,088,184 shares, which included 4,252,600 shares issuable upon exercise of warrants.

About Zevra: 

Zevra Therapeutics is a rare disease company melding science, data, and patient need to create transformational therapies for diseases with limited or no treatment options. With unique, data-driven clinical, regulatory, and commercialization strategies, the Company is overcoming complex drug development challenges to bring much-needed therapies to patients.   

Arimoclomol, Zevra’s orally-delivered, first-in-class investigational product candidate for the treatment of Niemann-Pick disease type C (“NPC”), has been granted orphan drug designation, Fast Track designation, Breakthrough Therapy designation and rare pediatric disease designation for the treatment of NPC by the U.S. Food and Drug Administration (“FDA”), and orphan medicinal product designation for the treatment of NPC by the European Medicines Agency (“EMA”).   

KP1077 is Zevra’s lead clinical candidate being developed to treat idiopathic hypersomnia (“IH”) and narcolepsy. KP1077 is comprised solely of serdexmethylphenidate (“SDX”), Zevra’s proprietary prodrug of d-methylphenidate (“d-MPH”).  The FDA has granted KP1077 orphan drug designation for the treatment of IH, and the U.S. Drug Enforcement Agency (“DEA”) has classified SDX as a Schedule IV controlled substance based on evidence suggesting SDX has a lower potential for abuse when compared to d-MPH, a Schedule II controlled substance. 

Early access programs are made available by Zevra Therapeutics, Inc. and its affiliates and are subject to the Company's Early Access Program (“EAP”) policy as published on its website at zevra.com.  Participation in these programs is subject to the laws and regulations of each jurisdiction under which each respective program is operated.  Eligibility for participation in any such program is at the treating physician's discretion.
