Company to host conference call and webcast TODAY, August 12, 2025, at 4:30 p.m. ET

CELEBRATION, Fla., Aug. 12, 2025 (GLOBE NEWSWIRE) -- Zevra Therapeutics, Inc. (NasdaqGS: ZVRA) (Zevra, or the Company), a commercial-stage company focused on providing therapies for people living with rare disease, today reported its financial results for the three and six months ended June 30, 2025.

“This is an exciting time of growth for Zevra,” said Neil F. McFarlane, Zevra’s President and Chief Executive Officer. “Following approval late last year, we are focused on executing the U.S. launch of MIPLYFFA®, and we believe the remarkable performance in the second quarter sets a strong foundation for continued momentum. As the only treatment that has been shown to halt disease progression by addressing its underlying pathology, we are invigorated by the meaningful impact MIPLYFFA is bringing to people diagnosed with Niemann-Pick disease type C (NPC). Now, with the recent submission of the Marketing Authorisation Application (MAA) in the E.U., we seek to expand these differentiated benefits to greater numbers of patients with this debilitating disease.”

• OLPRUVA: 1 prescription enrollment form during Q2 2025, bringing the total since product launch to 29. Market access has increased to 79% of covered lives.
  
  

Pipeline and Innovation Highlights

Based on our quarterly assessment of the recoverability of certain intangible assets and inventory related to OLPRUVA in accordance with U.S. GAAP, the prevailing trend for enrollments, paid authorizations, as well as market and competitive landscape dynamics, we have also recognized a non-cash charge of $58.7 million for impairment of intangible assets as of June 30, 2025.
  
  
  
  
• Operating Expenses: $24.2 million for Q2 2025, which includes non-cash stock compensation expense of $2.5 million. For Q2 2024, total operating expenses were $23.1 million.
  
  
  
  
  • R&D expense was $3.4 million for Q2 2025, which was a decrease of $7.1 million compared to Q2 2024 due primarily to a decrease in third-party costs upon completion of the KP1077 Phase 2 trial, combined with a decrease in personnel-related costs.
    
    
    
    
  • SG&A expense was $20.8 million for Q2 2025, which was an increase of $8.2 million compared to Q2 2024.

• Other Income: $147.9 million for Q2 2025, which includes $148.3 million of net proceeds from the sale of the PRV which closed on April 1, 2025, and offset by $0.4 million in non-cash fair value adjustment.
  
  
  
  
• Net Income (Loss): $74.7 million, or $1.24 per basic share and $1.21 per diluted share for Q2 2025, compared to a net loss of $(19.9) million, or $(0.48) per basic and diluted share, in Q2 2024.
  
  
  
  Excluding $148.3 million of net proceeds from the one-time PRV sale, the $58.7 million non-cash impairment charge related to intangible assets, and the $11.7 million inventory obsolescence charge recognized during the quarter, adjusted net loss was $(3.2) million, or $(0.06) adjusted net loss per basic and diluted share for Q2 2025¹.

¹Adjusted net loss and adjusted net loss per share are non-GAAP financial measures. Management believes that adjusted net loss and adjusted net loss per share provide useful information for investors, and management uses these supplemental measures to assess the Company’s operating performance. Adjusted net loss and adjusted net loss per share have limitations as analytical tools because they do not reflect all of the amounts associated with our results of operations as determined in accordance with U.S. GAAP. Additionally, they may not be comparable to similarly titled measures of other companies, including in our industry, limiting the usefulness of those measures for comparative purposes. Because of these limitations, these non-GAAP financial measures should be considered along with other operating and financial performance measures presented in accordance with U.S. GAAP. The presentation of these non-GAAP financial measures are not intended to be considered in isolation or as a substitute for, or superior to, financial information prepared and presented in accordance with U.S. GAAP.

About MIPLYFFA® (arimoclomol)

MIPLYFFA (arimoclomol) is Zevra’s approved therapy for the treatment of Niemann-Pick disease type C (NPC). Approved by the U.S. Food and Drug Administration on Sep. 20, 2024, MIPLYFFA (arimoclomol) increases the activation of the transcription factors EB (TFEB) and E3 (TFE3) resulting in the upregulation of coordinated lysosomal expression and regulation (CLEAR) genes. 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. In the pivotal phase 3 trial, MIPLYFFA halted disease progression compared to placebo over the one-year duration of the trial when measured by the only validated disease progression measurement tool, the NPC Clinical Severity Scale. MIPLYFFA has also received Orphan Medicinal Product designation by the European Medicines Agency (EMA) for the treatment of NPC. The extensive data generated for MIPLYFFA has shown long-term, meaningful clinical outcomes with 5 and in some patients 7 years of patient experience across more than 270 NPC patients worldwide through a Phase 2/3 clinical trial, Open-Label Extension (OLE) study, Expanded Access Programs (EAP), and a pediatric sub-study, which is the most expansive clinical development program in NPC to date. Zevra has submitted a Marketing Authorization Application to the European Medicines Agency for the evaluation of arimoclomol for the treatment of Niemann-Pick disease type C.

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 /medwatch.

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) is Zevra’s approved treatment for the treatment of certain UCDs. 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

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 U.S. FDA at 1-800-FDA-1088.
