FDA approval of MIPLYFFA™ and product launch cap third quarter filled with multiple commercial and clinical development milestones Zevra received rare pediatric disease Priority Review Voucher Company ends quarter with cash, cash equivalents and investments of $95.5 million Company to host conference call and webcast today, Nov. 12, 2024, 4:30 p.m. ET CELEBRATION, Fla., Nov. 12, 2024 (GLOBE NEWSWIRE) -- Zevra Therapeutics, Inc. (NasdaqGS: ZVRA) (Zevra, or the Company), a commercial-stage company focused on addressing unmet needs for the treatment of rare diseases, today reported its financial results for the third quarter ended Sept. 30, 2024, and provided corporate updates. “The third quarter was one of the most exciting and transformational periods in Zevra’s journey,” said Neil F. McFarlane, Zevra’s President and Chief Executive Officer. “After years of tireless effort, our team has achieved a major milestone with FDA approval of MIPLYFFA™ (arimoclomol), and we’re celebrating with the Niemann-Pick disease type C (NPC) community. We intend to achieve our goals with a high-performing team committed to execute, focus and innovate to drive our continued growth and long-term transformation.” Program Highlights On Sept. 20, the U.S. Food and Drug Administration (FDA) approved MIPLYFFA capsules as an orally delivered treatment for NPC. MIPLYFFA, the first NPC drug approved by the FDA, is indicated for use in combination with miglustat for the treatment of neurological manifestations of NPC in adult and pediatric patients 2 years of age and older. With the approval of MIPLYFFA, Zevra received a rare pediatric disease Priority Review Voucher (PRV) which the Company could monetize to help fund its growth. As of Oct. 31, Zevra has received 90 prescription enrollment forms for MIPLYFFA of which 30% are approved for reimbursement and are ready for fulfillment upon drug availability, consistent with the Company’s prior guidance of eight to 12 weeks post launch. Zevra has launched AmplifyAssist™, a comprehensive support program for caregivers and those eligible living with NPC or UCDs. OLPRUVA® had three new patient enrollments in the third quarter, and reimbursement coverage is at approximately 76% of covered lives. Improving OLPRUVA’s formulary position is a primary objective to make it the preferred treatment for UCDs. Zevra is refining its commercial strategy for OLPRUVA to focus on specific patient segments where there are fewer access barriers, and, together with The National Urea Cycle Disorders Foundation, launched a targeted patient education campaign highlighting the importance of prompt and accurate testing of blood ammonia levels, which, when elevated, may be a sign of a UCD. Campaign materials are available at www.checkammonia.com. The Company recently completed an End-of-Phase 2 meeting with the FDA for KP1077. The Agency indicated that a single pivotal study with appropriate confirmatory evidence will be sufficient to submit a new drug application (NDA). Zevra is evaluating strategic alternatives to advance clinical development and later, commercialization. The Phase 3 DiSCOVER trial of celiprolol for the treatment of Vascular Ehler-Danlos Syndrome (VEDS) is underway, and the Company has achieved its objective to restart enrollment and to begin dosing new patients, reporting that a total of 19 patients are now in the trial as of the end of the third quarter. Zevra is continuing its efforts to expand its partnerships with patient advocacy groups, treatment centers of excellence, and medical key opinion leaders. Corporate Highlights and Upcoming Milestones In August, Zevra completed an underwritten public offering of 10,615,385 shares of its common stock at an offering price of $6.50 per share for total net proceeds of approximately $64.5 million, after deducting underwriting discounts and commissions and offering expenses. Cantor and William Blair were joint book-running managers for the offering. Citizens JMP and H.C. Wainwright & Co. were co-managers. The Company completed a thorough portfolio assessment and developed a strategic plan for 2025 that builds from its 2024 accomplishments and furthers Zevra’s transformation towards becoming a leading rare disease company with a five-year vision to create value for patients and shareholders by organizing our priorities on four key pillars: Commercial Excellence, Pipeline and Innovation, Talent and Culture, and Corporate Foundation. Now focused on late-stage clinical development and commercial opportunities, Zevra has discontinued its in-house drug discovery activities and is closing its laboratory facilities in Iowa and Virginia. Future early research and development activities will be outsourced. Q3 2024 Financial Highlights Revenue, Net: $3.7 million, comprised of $2.6 million in net reimbursements from the French expanded access program (EAP) for arimoclomol, $1.1 million of royalties and other reimbursements under the AZSTARYS® license agreement, and de minimis OLPRUVA revenue. Cost of Goods Sold: $2.3 million, which includes recognition of $2.0 million in inventory obsolescence reserve expense related to OLPRUVA inventory that is nearing expiration. R&D Expenses: $10.9 million, which represents a decrease of $1.4 million compared to Q3 2023 due to the completion of the KP1077 phase 2 trial. SG&A Expenses: $16.2 million for Q3 2024, compared to $5.8 million in Q3 2023, which reflects the commercial team fully in place and actively engaged in commercial launch activities and patient services initiatives. This includes non-cash stock compensation of $6.1 million during the quarter, of which $2.5 million was performance-based upon the approval of MIPLYFFA. Net Loss: ($33.2) million, or ($0.69) per basic and diluted share for Q3 2024, compared to a net loss of ($10.4) million, or ($0.30) per basic and diluted share in Q3 2023. Cash Position: Cash, cash equivalents and investments were $95.5 million as of Sept. 30, 2024. Cash Runway Forecast: Based on the Company’s current operating plan, available cash, cash equivalents and investments are expected to extend Zevra’s cash runway into 2027, subject to continuing compliance with debt covenants. Cash runway forecast includes anticipated revenue from MIPLYFFA sales, reimbursements from the French EAP for arimoclomol, royalties under the AZSTARYS license agreement, and continued investments into our development pipeline programs. It does not include potential proceeds from a PRV sale.

MIPLYFFA has also been shown to reduce unesterified cholesterol in the lysosomes of human NPC fibroblasts. The clinical significance of these findings is not fully understood. MIPLYFFA was granted Breakthrough Therapy designation, Rare Pediatric Disease designation, Orphan Drug designation, and Fast Track designation by the FDA for the treatment of NPC. MIPLYFFA was further granted Orphan Medicinal Product designation by the European Medicines Agency (EMA) for the treatment of NPC. INDICATIONS AND USAGE MIPLYFFA is indicated 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. IMPORTANT SAFETY INFORMATION Hypersensitivity Reactions: Hypersensitivity reactions such as urticaria and angioedema have been reported in patients treated with MIPLYFFA during Trial 1: two patients reported both urticaria and angioedema (6%) and one patient (3%) experienced urticaria alone within the first two months of treatment. Discontinue MIPLYFFA in patients who develop severe hypersensitivity reactions. If a mild or moderate hypersensitivity reaction occurs, stop MIPLYFFA and treat promptly. Monitor the patient until signs and symptoms resolve. Embryofetal Toxicity: MIPLYFFA may cause embryofetal harm when administered during pregnancy based on findings from animal reproduction studies. Advise pregnant females of the potential risk to the fetus and consider pregnancy planning and prevention for females of reproductive potential. Increased Creatinine without Affecting Glomerular Function: Across clinical trials of MIPLYFFA, mean increases in serum creatinine of 10% to 20% compared to baseline were reported. These increases occurred mostly in the first month of MIPLYFFA treatment and were not associated with changes in glomerular function. During MIPLYFFA treatment, use alternative measures that are not based on creatinine to assess renal function. Increases in creatinine reversed upon MIPLYFFA discontinuation. The most common adverse reactions in Trial 1 (≥15%) in MIPLYFFA-treated patients who also received miglustat were upper respiratory tract infection, diarrhea, and decreased weight. Three (6%) of the MIPLYFFA-treated patients had the following adverse reactions that led to withdrawal from Trial 1: increased serum creatinine (one patient), and progressive urticaria and angioedema (two patients). Serious adverse reactions reported in MIPLYFFA-treated patients were hypersensitivity reactions including urticaria and angioedema. To report SUSPECTED ADVERSE REACTIONS, contact Zevra Therapeutics, Inc. at toll-free phone 1-844-600-2237 or FDA at 1 800-FDA-1088 or www.fda.gov/medwatch. Before prescribing MIPLYFFA, please read the full Prescribing Information, including Instructions for Use. Drug Interaction(s): Arimoclomol is an inhibitor of the organic cationic transporter 2 (OCT2) transporter and may increase the exposure of drugs that are OCT2 substrates. When MIPLYFFA is used concomitantly with OCT2 substrates, monitor for adverse reactions and reduce the dosage of the OCT2 substrate. Use in Females and Males of Reproductive Potential: Based on animal findings, MIPLYFFA may impair fertility and may increase post-implantation loss and reduce maternal, placental, and fetal weights. Renal Impairment: The recommended dosage of MIPLYFFA, in combination with miglustat, in patients with an eGFR ≥15 mL/minute to <50 mL/minute is lower than the recommended dosage (less frequent dosing) in patients with normal renal function. MIPLYFFA capsules for oral use are available in the following strengths: 47 mg, 62 mg, 93 mg, and 124 mg. 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 KP1077 Serdexmethylphenidate (SDX) is Zevra’s proprietary prodrug of d-methylphenidate (d-MPH) and is the sole active pharmaceutical ingredient (API) of KP1077. KP1077 has been granted Orphan Drug designation by the FDA, and by the European Commission, for the treatment of Idiopathic Hypersomnia, or IH. 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. In addition, KP1077 has intellectual property protection through 2037. 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.
