LEXINGTON, Mass. and AMSTERDAM, Nov. 02, 2026 (GLOBE NEWSWIRE) — uniQure N.V. (NASDAQ: QURE), a leading gene therapy company advancing transformative therapies for patients with severe medical needs, today announced the U.S. Food and Drug Administration (FDA) has accepted for review the Biologics License Application (BLA) for ifezuntirgene inilparvovec, an investigational gene therapy for the treatment of Huntington’s disease submitted under the Accelerated Approval pathway. The application has been granted Priority Review with a Prescription Drug User Fee Act (PDUFA) target action date of May 1, 2027.
In its acceptance letter, the FDA stated that they are tentatively planning to discuss this application at an Advisory Committee meeting. The Company will be notified once the date and timelines have been finalized.
“The FDA’s acceptance of our BLA for review marks an important milestone for the Huntington’s disease community, which has waited generations for a treatment that changes the course of this devastating disease,” stated Matt Kapusta, chief executive officer of uniQure. “Backed by compelling data from our Phase I/II studies, we believe ifezuntirgene inilparvovec has the potential to become the first disease modifying treatment for Huntington’s disease. With the FDA’s priority review underway, we will work in conjunction with the Agency, clinicians, and the Huntington’s community to support the review process. The confirmatory trial remains a key priority, with screening anticipated to begin by year end and the study is expected to be well underway by the time of potential approval.”
The BLA is supported by the previously announced 36-month data analysis from the Phase I/II clinical study of ifezuntirgene inilparvovec, compared to a propensity score-matched external control derived from the Enroll-HD natural history database, as previously announced on September 24, 2025.
The Company and FDA have aligned on key elements of the confirmatory study design. The study is designed as a randomized, standard-of-care trial enrolling approximately 200 patients in a 2:1 ratio of ifezuntirgene inilparvovec to standard of care, with Total Functional Capacity (TFC) as the primary endpoint at 36 months. The Company plans to initiate patient screening in the U.S. by the end of 2026.
Ifezuntirgene inilparvovec is the first investigational therapy for Huntington’s disease to have received Breakthrough Therapy and Regenerative Medicine Advanced Therapy (RMAT) designations from the FDA. Ifezuntirgene inilparvovec also holds Fast Track designation from the FDA.
About Ifezuntirgene Inilparvovec (AMT-130)
Ifezuntirgene inilparvovec is a novel gene therapy candidate for the treatment of Huntington’s disease, which utilizes a proprietary, gene-silencing miQURE® platform and incorporates a miRNA, specifically designed to silence the huntingtin gene and the potentially highly toxic exon 1 protein fragment. Treated patients receive a single administration through targeted, MRI-guided, convection-enhanced stereotactic neurosurgical delivery directly into the striatum (caudate and putamen).
About the Phase I/II Clinical Program of Ifezuntirgene Inilparvovec
uniQure is conducting two multi-center Phase I/II clinical studies evaluating the safety, tolerability, and efficacy of ifezuntirgene inilparvovec for the treatment of Huntington’s disease.
In total, the Phase I/II clinical studies have dosed 51 patients with ifezuntirgene inilparvovec. The U.S. randomized study enrolled 26 patients who received either a single administration of ifezuntirgene inilparvovec (n=6 low dose; n=10 high dose) or a sham procedure (n=10); four control patients subsequently crossed over to treatment after approximately 12 months. The European open-label study enrolled 13 patients (n=6 low dose; n=7 high dose). A third cohort of 12 patients explored both doses in combination with immunosuppression, and a fourth cohort of six U.S. patients is evaluating the high dose in patients with lower striatal volumes compared to those enrolled in previous cohorts.

About Huntington’s Disease
Huntington’s disease is a rare, inherited neurodegenerative disorder that leads to motor symptoms including chorea, behavioral abnormalities and cognitive decline resulting in progressive physical and mental deterioration. The disease is an autosomal dominant condition with a disease-causing CAG repeat expansion in the first exon of the huntingtin gene that leads to the production and aggregation of abnormal protein in the brain. Approximately 75,000 people have Huntington’s disease in the U.S.1, EU2, and the UK3, with hundreds of thousands of others at risk of inheriting the disease. Despite the clear etiology of Huntington’s disease, there are currently no approved therapies to delay the onset or to slow the disease’s progression.
About uniQure
uniQure is delivering on the promise of gene therapy – single treatments with potentially curative results. The approvals of uniQure’s gene therapy for hemophilia B – an historic achievement based on more than a decade of research and clinical development – represent a major milestone in the field of genomic medicine and ushers in a new treatment approach for patients living with hemophilia. uniQure is now advancing a pipeline of proprietary gene therapies for the treatment of patients with Huntington’s disease, refractory temporal lobe epilepsy, Fabry disease, and other severe diseases. www.uniQure.com
