uniQure Announces Recommendations from Data Safety Monitoring Board of Phase I/II Clinical Trial of AMT-130 for the Treatment...

uniQure N.V. (NASDAQ: QURE), a leading gene therapy company advancing transformative therapies for patients with severe medical needs, today announced that the independent Data Safety Monitoring Board (DSMB) overseeing the Phase I/II clinical trial of AMT-130 for the treatment of Huntington’s disease has met and reviewed 90-day safety data from the first two patients enrolled in the trial. No significant safety concerns were noted to prevent further dosing, and the next two patients are now cleared for enrollment in the study. The Phase I/II study is a double-blind, randomized clinical trial being conducted in the United States. One patient has been treated with AMT-130, and one patient received the imitation surgery.

“We are very pleased with the positive outcome from this first DSMB meeting,” said Ricardo Dolmetsch, president of research and development at uniQure. “We will now advance the study and expect to enroll the next two patients as soon as possible.”

About the Phase I/II Clinical Trial of AMT-130

The Phase I/II clinical trial of AMT-130 for the treatment of Huntington’s disease will explore the safety, tolerability, and efficacy signals in 26 patients with early manifest Huntington’s disease randomized to treatment with AMT-130 or an imitation (sham) surgery. The five-year, multi-center trial consists of a blinded 12-month core study period followed by unblinded long-term follow-up. Patients will receive a single administration of AMT-130 through MRI-guided, convection-enhanced stereotactic neurosurgical delivery directly into the striatum (caudate and putamen). Additional details are available on www.clinicaltrials.gov (NCT04120493).

AMT-130 is uniQure’s first clinical program focusing on the central nervous system (CNS) incorporating its proprietary miQURE™ platform.

About Huntington’s DiseaseHuntington’s disease is a rare, inherited neurodegenerative disorder that leads to motor symptoms including chorea, and 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. Despite the clear etiology of Huntington’s disease, there are no currently approved therapies to delay the onset or to slow the disease’s progression.
