As part of the deal, Voyager will hold all US rights to its lead product programmes in Parkinson’s disease (VY-AADC01) and Friedreich’s ataxia (VY-FXN01).

Voyager noted that it will split US profits with Genzyme for the Huntington’s disease programme (VY-HTT01). Its amyotrophic lateral sclerosis (ALS) programme (VY-SOD101) is not part of the collaboration and retains worldwide rights to this programme.

Genzyme president and CEO David Meeker said: "We’ve been working in gene therapy for more than 20 years, and our commitment remains strong because we believe in its promise to transform the lives of patients with debilitating diseases."
