Celebration, FL – August 13, 2024 – 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 second quarter ended June 30, 2024. 

“During the second quarter, we made steady progress executing on our strategic objectives,” said Neil F. McFarlane, President and Chief Executive Officer of Zevra. “We are encouraged by favorable vote from the FDA's Genetic Metabolic Diseases Advisory Committee, that data presented support that arimoclomol is effective in the treatment in patients with Niemann Pick disease type C.  While the vote is non-binding, we believe it is an important factor as the FDA completes its consideration for approval.  Additionally, we continue the launch of OLPRUVA with a keen focus on driving patient awareness and intend to use the same commercial team to launch arimoclomol, if approved. Additionally, we expect to meet with the FDA to discuss the design of a pivotal Phase 3 trial to study KP1077 in idiopathic hypersomnia at the end of third quarter.”   

“We continue to be prudent in our capital allocation as we focus on creating long-term value for stockholders,” said R. LaDuane Clifton, Zevra’s Chief Financial Officer and Treasurer. “Our recent underwritten offering provided net proceeds to the Company of $64.5 million, along with attracting a cadre of institutional investors well known as long term supporters of innovation and building momentum as we lean into our near-term catalysts while also extending our cash runway.”

Q2 2024 Corporate Highlights:

Overview of Q2 2024 Financial Results:

Net revenue for Q2 2024 was $4.4 million, compared to net revenue of $8.5 million in Q2 2023. The components of revenue during the second quarter included $3.1 million in net reimbursements from the French EAP for arimoclomol, $1.3 million of royalties and other reimbursements under the AZSTARYS® License Agreement, and de minimis OLPRUVA revenue via sales to the new specialty pharmacy, Orsini, were offset by returns from the prior pharmacy in Q2 2024. In addition, cost of goods sold was inflated during the quarter due to recognition of a $3.2 million obsolescence reserve against OLPRUVA inventory which is nearing expiration.  This excess inventory was ordered prior to our acquisition of Acer, and the delayed launch impacted the rate of usage, leading to the need for this reserve to be recognized in the quarter.

Research and development (R&D) expenses were $10.5 million for Q2 2024, compared to $7.4 million in Q2 2023.  The increase in R&D expenses was primarily driven by an increase in spending for the KP1077 Phase 2 clinical trial and an increase in personnel-related costs, partially offset by a decrease in third-party costs related to arimoclomol.  

Selling, general and administrative (SG&A) expenses were $12.6 million for Q2 2024, compared to $6.6 million in Q2 2023. The period-over-period increase reflects the commercial team in place for the entire quarter and actively engaged in activities to build awareness and provide patient services related to OLPRUVA, leading to an increase in personnel costs due to the additional headcount and an increase in other expenses related primarily to the launch of OLPRUVA

Net loss for Q2 2024 was ($19.9) million, or ($0.48) per basic and diluted share, compared to a net loss of ($2.6) million, or ($0.08) per basic and diluted share for Q2 2023. 

As of June 30, 2024, total cash, cash equivalents, and investments were $49.3 million, a decrease of $3.4 million compared to $52.7 million as of March 31, 2024.  The decrease was driven, in part, by increased third-party R&D costs related to the KP1077 clinical development program and increased SG&A expenses during the period as the Company invested in its commercial infrastructure. 

As of June 30, 2024, total shares of common stock outstanding were 41,991,464, and fully diluted common shares were 57,324,496, which included 5,483,537 shares issuable upon exercise of warrants. 

On April 5, 2024, the Company announced the refinancing of its existing debt with up to $100 million in committed capital, which strengthened its balance sheet, simplified its debt structure, and provided non-dilutive capital flexibility. The refinancing was led by Perceptive Advisors and HealthCare Royalty Partners, premier biotech investors. From the initial draw of $60 million at closing, the Company refinanced its existing debt of $43 million and added an incremental $14 million in net cash proceeds to the cash balance after fees and discounts. A second tranche of up to $20 million is available at the Company’s discretion until October 5, 2025, and a third tranche of up to $20 million will become available upon approval of arimoclomol, in each case subject to certain terms and conditions

On August 12, 2024, the Company completed an underwritten public offering, further strengthening its balance sheet. The underwriters fully exercised their overallotment option, resulting in the issuance of approximately 10.6 million shares at a price of $6.50 per share, raising net proceeds of $64.5 million after fees and expenses. Combining the net proceeds from this offering with our existing resources, pro forma June 30, 2024 total cash, cash equivalents and investments was $113.8 million.

Following the closing of the underwritten public offering on August 12, 2024, pro forma June 30, 2024, common shares and fully diluted shares outstanding were 52,606,849 and 67,939,881, respectively.  No warrants were issued as part of the underwritten public offering

Based on our current operating plan, available cash, cash equivalents and investments, including proceeds from the underwritten offering closed in August are expected to extend our cash runway into the first quarter of 2027, subject to continuing compliance with our debt covenants.

About Urea Cycle Disorders

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.ⁱ  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.

About OLPRUVA®

OLPRUVA (sodium phenylbutyrate) was approved for the treatment of certain UCDs in December 2022 and has recently been marketed under the brand name, OLPRUVA®.  OLPRUVA (sodium phenylbutyrate) for oral suspension is a prescription medicine used along with certain therapies, including changes in diet, for the long-term management of adults and children weighing 44 pounds (20 kg) or greater and with a body surface area (BSA) of 1.2 m² or greater, with UCDs, involving deficiencies of carbamylphosphate synthetase (CPS), ornithine transcarbamylase (OTC), or argininosuccinic acid synthetase (AS). OLPRUVA is not used to treat rapid increase of ammonia in the blood (acute hyperammonemia), which can be life-threatening and requires emergency medical treatment.   For more information, please visit www.OLPRUVA.com

Important Safety Information

Certain medicines may increase the level of ammonia in your blood or cause serious side effects when taken during treatment with OLPRUVA. Tell your doctor about all the medicines you or your child take, especially if you or your child take corticosteroids, valproic acid, haloperidol, and/or probenecid.

OLPRUVA can cause serious side effects, including: 1) nervous system problems (neurotoxicity). Symptoms include sleepiness, tiredness, lightheadedness, vomiting, nausea, headache, confusion, 2) low potassium levels in your blood (hypokalemia) and 3) conditions related to swelling (edema). OLPRUVA contains salt (sodium), which can cause swelling from salt and water retention. Tell your doctor right away if you or your child get any of these symptoms. Your doctor may do certain blood tests to check for side effects during treatment with OLPRUVA. If you have certain medical conditions such as heart, liver or kidney problems, are pregnant/planning to get pregnant or breast-feeding, your doctor will decide if OLPRUVA is right for you.

The most common side effects of OLPRUVA include absent or irregular menstrual periods, decreased appetite, body odor, bad taste or avoiding foods you ate prior to getting sick (taste aversion). These are not all of the possible side effects of OLPRUVA. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

About Niemann-Pick Disease Type C (NPC)

Niemann-Pick disease type C (NPC) is an ultra-rare, progressive, and 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. 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, investigational drug product candidate for the treatment of NPC, has been granted Orphan Drug designation, Fast Track designation, Breakthrough Therapy designation, and Rare Pediatric Disease designation by the FDA, and Orphan Medicinal Product designation for the treatment of NPC by the European Medicines Agency (EMA). The FDA has accepted the resubmission of the NDA for arimoclomol and has set a user fee foal action date (PDUFA date) of September 21, 2024

About Idiopathic Hypersomnia (IH)

Idiopathic hypersomnia (IH) is a rare sleep disorder characterized by excessive daytime sleepiness (EDS).  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, based on claims data, that approximately 37,000 patients in the United States are currently diagnosed with IH, although the total patient population may be much larger due to some patients who have not yet been diagnosed, have been misdiagnosed, or are not currently seeking treatment.

About KP1077

KP1077 (serdexmethylphenidate or SDX) is Zevra’s proprietary prodrug of d-methylphenidate (d-MPH) and its sole active pharmaceutical ingredient (API).  KP1077 has been granted Orphan Drug Designation by the U.S. Food and Drug Administration (FDA), and by the European Commission, for the treatment of IH. 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. In addition, KP1077 has intellectual property protection though 2037 and potentially beyond.

About Celiprolol

Celiprolol is an investigational clinical candidate for the treatment of Vascular Ehlers-Danlos Syndrome (VEDS).  Celiprolol has been granted Orphan Drug and Breakthrough Therapy Designations by the FDA. Zevra recently restarted enrollment in the Phase 3 trial, known as DiSCOVER trial being conducted under a Special Protocol Assessment (SPA) agreement with the U.S. FDA. Celiprolol’s mechanism of action is designed to reduce the mechanical stress on collagen fibers within the arterial wall through vascular dilation and smooth muscle relaxation.

About Vascular Ehlers-Danlos Syndrome

Vascular Ehlers-Danlos syndrome is a rare genetic cardiovascular disorder which impairs collagen 3 rich connective tissue and leads to vascular and hollow organ ruptures.

It is estimated that approximately 7,500 patients in the United States are currently diagnosed patients with VEDS. There remains an unmet need with no approved treatment in the U.S. and celiprolol is currently the standard of care in Europe.
