Celebration, FL – August 14, 2023 – Zevra Therapeutics, Inc. (NasdaqGS: ZVRA) (Zevra, or the Company), a rare disease therapeutics company, today provided corporate updates and reported its financial results for the quarter ended June 30, 2023.

Recent Business and Corporate Highlights:

“The first half of 2023 has been a time of dynamic change for Zevra, and we are pleased with our progress in executing on the key priorities for our programs in Niemann-Pick Disease type C (NPC) and Idiopathic Hypersomnia (IH),” said Christal Mickle, interim Chief Executive Officer and Chief Development Officer at Zevra. “We have made meaningful progress in our preparation of the arimoclomol NDA, including a productive and collaborative pre-submission meeting with the FDA earlier this month, which provides confidence as we anticipate re-submission of the NDA package by the end of this year.  In addition, the KP1077 program is on track, and we are pleased with progress toward the AZSTARYS® net sales milestones and the momentum toward the possibility of earning a second net sales milestone in 2023.  Zevra has several upcoming catalysts for value creation, and we believe our focus on developing and commercializing therapies for rare diseases with a patients-first approach will lead to better therapies for the communities we serve.”

Tamara A. Favorito, Zevra’s Board Chair added, “Just last week, we announced the addition of Thomas Anderson to our Board of Directors, which was an important step in executing the plan of Board refreshment we announced on May 8, 2023.  Tom brings to Zevra relevant experience in managing successful commercial teams, and in navigating complex drug development challenges, including a track record of success in strategic roles within the rare disease space. Our search to identify both a new chief executive officer and an additional replacement Board member continues to progress. There are excellent candidates available, and I am confident that we will fill these roles in the near-term.”

Overview of Q2 2023 Financial Results:

Net revenue for Q2 2023 was $8.5 million compared to Q2 2022 net revenue of $1.3 million. AZSTARYS milestone revenues, ongoing royalties from AZSTARYS, and the French early access program for arimoclomol primarily drove Q2 2023 net revenue. 

Research and development (R&D) expenses were $7.4 million for Q2 2023, compared to $4.8 million in Q2 2022. The increase in R&D expenses were primarily driven by the ongoing Phase 2 clinical trial in KP1077, along with the ongoing work to prepare the arimoclomol NDA for resubmission.   

General and administrative (G&A) expenses were $7.0 million for Q2 2023, compared to $3.6 million in Q2 2022. The period-over-period increase was primarily related to an increase in personnel costs and professional fees.  

Net loss for Q2 2023 was ($5.1) million, or ($0.15) per basic and diluted share, compared to a net loss of ($24.0) million, or ($0.70) per basic and diluted share for the same period in 2022. The net loss during Q2 2022 included recognition of $17.7 million of expense related to acquired in-process research and development from the arimoclomol asset acquisition which was immediately expensed.

 As of June 30, 2023, total cash, cash equivalents, and investments were $87.4 million, a decrease of $7.9 million compared to $95.3 million as of March 31, 2023.  The decrease was driven, in part, by increased third-party R&D costs related to the KP1077 clinical trial program and the arimoclomol program and increased G&A expenses during the period.   The balance as of June 30, 2023, does not include the cash payment of the $5 million net sales milestone earned under the AZSTARYS license agreement which was received after quarter-end.

Based on the Company’s current operating forecast, existing cash, cash equivalents, and investments are expected to be sufficient to continue operations into 2026.  

As of June 30, 2023, total shares of common stock outstanding were 33,928,005, and fully diluted common shares outstanding were 49,315,197, which included 4,252,490 shares issuable upon exercise of warrants.

About Niemann-Pick disease type C (NPC):

Niemann-Pick disease type C (NPC) is an ultra-rare and progressive, neurodegenerative lysosomal storage disorder characterized by an inability of the body to transport cholesterol and other lipids within the cell, leading to an accumulation of these substances in various tissue areas, including brain tissue.  The disease is caused by mutations in the NPC1 or NPC2 genes which are responsible for making lysosomal proteins and is an autosomal recessive trait.  Both children and adults can be affected by NPC with varying clinical presentations.  Those living with NPC lose independence due to physical and cognitive limitations, with key neurological impairments presenting in speech, cognition, swallowing, ambulation, and fine motor skills.  Disease progression is irreversible and can be fatal within months or take years to be diagnosed and advance in severity.

About Arimoclomol:

Arimoclomol, Zevra’s orally-delivered, first-in-class investigational product candidate for the treatment of NPC, has been granted orphan drug designation, Fast Track designation, Breakthrough Therapy designation and rare pediatric disease designation for NPC by the FDA, and orphan medicinal product designation for the treatment of NPC by the European Medicines Agency (EMA).  The arimoclomol NDA is currently being prepared for resubmission to the FDA.

About Idiopathic Hypersomnia (IH):

Idiopathic hypersomnia (IH) is a rare sleep disorder characterized by excessive daytime sleepiness. Patients with IH experience 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,” severe “brain fog”, and often fall asleep unintentionally or at inappropriate times. These symptoms of IH often lead to further, even more debilitating problems such as memory lapses, difficulty maintaining focus, and depression.

It is estimated that approximately 37,000 patients in the United States are currently diagnosed with IH and seeking treatment, although the total patient population may be much larger due to some patients not seeking treatment or being undiagnosed or misdiagnosed.

About Narcolepsy:

Narcolepsy is a chronic debilitating central disorder of hypersomnolence. The primary symptom of narcolepsy is excessive daytime sleepiness characterized by daily episodes of an irrepressible need to sleep or daytime lapses into sleep. Patients with narcolepsy have an abnormal rapid eye movement (REM) sleep phase which can cause disrupted nighttime sleep, sleep paralysis and sleep-related hallucinations during sleep-wake transitions. Narcolepsy has severe personal, social, and economic consequences. Patients with narcolepsy experience substantial impairment of their mental and physical wellbeing, and depression and anxiety are common. Cognitive dysfunctions such as difficulty to focus and memory lapses (also referred to as ‘brain fog’) are frequently reported. The many symptoms experienced by patients with narcolepsy result in a high disease burden and poor quality of life.

Narcolepsy is categorized in to two types: narcolepsy type 1 (NT1) and type 2 (NT2). NT1 is considered a distinct disease entity characterized in part by loss of hypocretin neurons and symptoms of cataplexy (sudden, brief attacks of muscle weakness sometimes resulting in the body to fall uncontrollably, often triggered by strong emotions). When narcolepsy presents without cataplexy and with normal hypocretin-1 concentrations in the cerebrospinal fluid (CSF), it is categorized as NT2 (Hypocretin-1 is also known as orexin-A, a neuropeptide involved in regulating sleep-wake cycles).

The combined worldwide prevalence of both types of narcolepsy has been estimated to be 25-50 per 100,000 people. Epidemiological studies using well-defined criteria for assessing the prevalence of narcolepsy (both NT1 and NT2) estimate incidence rates ranging from 31 to 79 per 100,000 people corresponding to approximately 100,000 to 260,000 total patients in the United States.

About SDX and KP1077:

Serdexmethylphenidate (SDX) is Zevra’s proprietary prodrug of d-methylphenidate (d-MPH) and the sole active pharmaceutical ingredient (API) in KP1077, Zevra’s lead clinical candidate being developed as a treatment for idiopathic hypersomnia (IH) and narcolepsy. Zevra is currently enrolling a multicenter, dose-optimizing, double-blind, placebo-controlled, randomized-withdrawal Phase 2 clinical trial to evaluate safety and efficacy of KP1077 as a treatment for IH. For more information regarding the Phase 2 trial, visit www.clinicaltrials.gov.

SDX is also the primary API in AZSTARYS®, a once-daily product for the treatment of attention deficit hyperactivity disorder (ADHD) in patients ages six and older being commercialized in the U.S. by Corium, Inc.

KP1077 has been granted Orphan Drug Designation by the U.S. Food and Drug Administration (FDA) for the treatment of IH, and the U.S. Drug Enforcement Agency (DEA) has classified SDX, the sole API in KP1077, 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.
