If approved, etranacogene dezaparvovec would be the first gene therapy option for people living with hemophilia B LEXINGTON, Mass. and AMSTERDAM, May 24, 2022 (GLOBE NEWSWIRE) -- 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 accepted for priority review the Biologics License Application (BLA) submitted by CSL Behring for etranacogene dezaparvovec, an investigational gene therapy for the treatment of adults with hemophilia B. CSL Behring is uniQure’s global commercialization partner for etranacogene dezaparvovec and is solely responsible for all regulatory activities, including filings and agency interactions, associated with etranacogene dezaparvovec. uniQure led the multi-year clinical development of etranacogene dezaparvovec, including the pivotal Phase III HOPE-B clinical trial, and the company will be responsible for the global commercial supply of etranacogene dezaparvovec. "Etranacogene dezaparvovec has the potential to be the first gene therapy approved in hemophilia B and the acceptance of the BLA marks an important milestone in uniQure’s mission of delivering the promise of gene therapy to people living with rare diseases,” stated Matt Kapusta, chief executive officer of uniQure. “uniQure has been a leader in gene therapy for nearly 25 years and, if approved, etranacogene dezaparvovec would represent our second gene therapy to complete its journey to patients. We are proud of this accomplishment, which is a culmination of significant contributions from all our employees, clinical investigators and the hemophilia community. We are pleased with the promising results generated from our HOPE-B pivotal study, the largest gene therapy trial in hemophilia B to date and, assuming FDA approval, we look forward to partnering with our colleagues at CSL Behring to bring this life-changing treatment option to people with hemophilia B.” Etranacogene dezaparvovec was specifically designed to make near-normal blood-clotting ability possible by addressing the underlying cause of hemophilia B: a faulty gene that causes a deficiency in clotting Factor IX (FIX). Etranacogene dezaparvovec has been shown in clinical trials to significantly reduce the rate of annual bleeds in trial participants after a single one-time infusion and, if approved, would be the first ever gene therapy treatment option for the hemophilia B community. The BLA is supported by results from the pivotal HOPE-B trial, which demonstrated in trial participants a reduction in adjusted annualized bleeding rate (ABR) of 64% and superiority to prophylaxis treatment at 18 months post-treatment compared to a 6-month run in period (p=0.0002). Priority review of a BLA is reserved for medicines that, if approved, would be potentially significant improvements in the safety or effectiveness of the treatment, diagnosis, or prevention of serious conditions when compared to standard applications. Upon acceptance for priority review, the FDA goal is to take action on the BLA in 6 months as compared to 10 months for standard review. Previously, the European Medicines Agency (EMA) accepted the Marketing Authorization Application (MAA) for etranacogene dezaparvovec under its accelerated assessment procedure. About Hemophilia B About Gene Therapy in Hemophilia B About Etranacogene Dezaparvovec About the Pivotal HOPE-B Trial Results from the pivotal HOPE-B study demonstrated that etranacogene dezaparvovec produced mean FIX activity of 39.0 IU/dL at six months and 36.9 IU/dL at 18 months post infusion. After the six-month lead-in period post-infusion, the adjusted annualized bleeding rate (ABR) for all bleeds was reduced by 64 percent (4.19 to 1.51 p=0.0002) and all FIX-treated bleeds was reduced by 77 percent (3.65 to 0.83; p<0.0001) over months seven to 18. In addition, 98 percent of subjects treated with a full dose of etranacogene dezaparvovec discontinued use of prophylaxis, with an overall 97 percent reduction in mean unadjusted annualized FIX consumption of 257338.8 IU/yr/participant to 8486.6 IU/yr/participant (from lead-in period to months 13-18). Etranacogene dezaparvovec was generally well-tolerated with the majority of adverse events (80.4 percent) considered mild. One death resulting from urosepsis and cardiogenic shock in a 77-year-old patient at 65 weeks following dosing was considered unrelated to treatment by investigators and the company sponsor. A serious adverse event of hepatocellular carcinoma was determined to be unrelated to treatment with etranacogene dezaparvovec by independent molecular tumor characterization and vector integration analysis. No inhibitors to FIX were reported. About uniQure uniQure Forward-Looking Statements This press release contains forward-looking statements.
