LEXINGTON, Mass. and AMSTERDAM, the Netherlands (GLOBE NEWSWIRE) — uniQure N.V. (NASDAQ:QURE), a leading gene therapy company advancing transformative therapies for patients with severe unmet medical needs, today announced that it has enrolled its first patient in the Phase III HOPE-B pivotal study of AMT-061, an investigational AAV5-based gene therapy incorporating the FIX-Padua variant for the treatment of patients with severe and moderately severe hemophilia B.

AMT-061 has been granted Breakthrough Therapy Designation by the U.S. Food and Drug Administration and access to the Priority Medicines (PRIME) regulatory initiative by the European Medicines Agency.

“AMT-061 has the potential to be a major advancement in gene therapy for patients affected by hemophilia B,” stated Steven Pipe, M.D., professor of pediatrics and pathology and pediatric medical director of the hemophilia and coagulation disorders program at the University of Michigan and principal investigator of the HOPE-B clinical trial. “A one-time treatment, such as AMT-061, could be life-changing for these patients, many of whom struggle to manage ongoing challenges, including compliance with frequent infusions and recurrent episodes of bleeding.”

“We are delighted to have enrolled the first patient in this Phase III pivotal study of a gene therapy for patients with hemophilia B,” said Steve Zelenkofske, D.O., chief medical officer at uniQure. “This represents a significant milestone for uniQure as we advance a potentially best-in-class gene therapy for patients with this life-altering disorder. In addition to advancing our pivotal trial, we have also initiated patient recruitment for our Phase IIb dose-confirmation study and expect to commence enrollment in July. We look forward to announcing top-line FIX data from the dose-confirmation study before the end of the year.”

About AMT-061

AMT-061 consists of an AAV5 viral vector carrying a gene cassette with the Padua variant of Factor IX (FIX-Padua). FIX-Padua has been reported to provide an approximate 8 to 9-fold increase in FIX activity compared to the wild-type FIX protein, as used in AMT-060. AAV5-based gene therapies have been demonstrated to be safe and well-tolerated in a multitude of clinical trials, including three uniQure trials conducted in 22 patients in hemophilia B and other indications. No patient treated in clinical trials with the Company’s AAV5 gene therapies has experienced any T-cell-mediated immune response to the capsid.
