LEXINGTON, Mass. and AMSTERDAM — uniQure N.V. (NASDAQ: QURE), a leading gene therapy company advancing transformative therapies for patients with severe medical needs, today announced that the U.S. Food and Drug Administration (FDA) has granted Breakthrough Therapy designation to AMT-130 for the treatment of Huntington’s disease, a rare, inherited neurodegenerative disorder for which there are currently no disease-modifying therapies available. This designation is in addition to Regenerative Medicine Advanced Therapy (RMAT) designation, Orphan Drug designation and Fast Track designation, all previously granted by the FDA to AMT-130.
“Receiving Breakthrough Therapy designation underscores both the urgent need for effective treatments for Huntington’s disease and the encouraging interim data demonstrating that AMT-130 has the potential to slow disease progression,” said Walid Abi-Saab, M.D., chief medical officer of uniQure. “It’s a powerful recognition of the promise of AMT-130 and the important progress we’ve made. We deeply value the FDA’s continued commitment to advancing innovative gene therapies for patients with critical unmet needs, and we look forward to working closely with the agency to bring AMT-130 to the Huntington’s disease patient community as quickly as possible.”
The Breakthrough Therapy designation is supported by clinical data from the ongoing Phase I/II trials of AMT-130 for the treatment of Huntington’s disease. In July 2024, uniQure presented interim data at 24 months that showed dose-dependent slowing of disease progression based on the cUHDRS of treated patients compared to a propensity-weighted natural history. To date, a total of 45 patients have received AMT-130.
Breakthrough Therapy designation is intended to expedite the development and review of investigational therapeutic candidates that are intended to treat a serious condition and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over available therapy on a clinically significant endpoint(s). In general, the preliminary clinical evidence should show a clear advantage over available therapy. A drug that receives Breakthrough Therapy designation is eligible for all Fast Track designation features, intensive guidance on an efficient drug development program, and FDA commitment involving senior managers1.
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. According to 2021 study in Neuroepidemiology, approximately 70,000 people have been diagnosed with Huntington’s disease in the U.S. and Europe, 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.
