uniQure Announces Hemophilia B Gene Therapy Program To Enter Pivotal Study With FIX-Padua Variant in 2018

19. Oktober 2017
  • AMT-060 with the FIX-Padua Modification (AMT-061) Demonstrates Substantial Increase in FIX Activity in Non-human Primates
  • Plans to Initiate Pivotal Study with Enhanced AMT-061 in 2018
  • Achieves Alignment with FDA on Streamlined Clinical and Regulatory Strategy for AMT-061, Which Will be Included Under Existing Breakthrough Therapy Designation
  • Acquires a Patent Family Covering FIX-Padua in Hemophilia B

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 medical needs, today announced that following multi-disciplinary meetings with the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA), the company plans to expeditiously advance AMT-061, which combines an AAV5 vector with the FIX-Padua mutant, into a pivotal study in 2018 for patients with severe and moderately severe hemophilia B.

AMT-061 and AMT-060, the latter of which has been tested in 10 patients in an ongoing Phase I/II clinical trial, are identical in structure apart from two nucleotide substitutions in the coding sequence for FIX.  The gene variant, referred to as FIX-Padua, expresses a protein with a single amino acid substitution that has been reported in multiple preclinical and nonclinical studies to provide an approximate 8 to 9-fold increase in FIX activity compared to the wild-type FIX protein. All other critical quality attributes of AMT-061 are expected to be comparable to those of AMT-060, as AMT-061 utilizes the same AAV5 capsid and proprietary insect cell-based manufacturing platform.

“Our mission in hemophilia B has always been to develop the safest and most effective gene therapy with the broadest application to patients. We believe AMT-061 moves us closer to this goal, as it has the potential to provide optimized clinical and tolerability benefits to nearly all severe and moderately severe patients with hemophilia B,” stated Matthew Kapusta, chief executive officer of uniQure.  “We are delighted to have received constructive guidance from both the FDA and EMA, which we believe allows us to expeditiously advance AMT-061 into a pivotal study next year, as previously planned. In anticipation of this, we have begun GMP production of AMT-061 in our Lexington facility and preparations for the pivotal study are underway.”

“I believe AMT-061 has the potential to be an important gene therapy for patients suffering with 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. “Based on the data generated to date, AMT-061 may be the first gene therapy to provide durable, curative benefits to nearly all patients with hemophilia B, without the complications associated with capsid-related immune responses.  I very much look forward to serving as an investigator in this exciting Phase III program.”
