Newport Beach, Calif. – May 16, 2022 – CureDuchenne, a leading global nonprofit focused on finding and funding a cure for Duchenne muscular dystrophy (DMD), today released a webinar on the upcoming opening of U.S. trial sites for Pfizer’s CIFFREO trial, a phase 3 study in ambulatory boys with DMD to assess the safety and efficacy of an investigational mini-dystrophin gene therapy. In the webinar, Pfizer’s global clinical lead for rare neurological diseases, Beth Belluscio, MD-PhD, presents critical updates on Pfizer’s CIFFREO trial including trial design, safety considerations, key inclusion/exclusion criteria, and more.

“We’re very excited that Pfizer’s global gene therapy ambulatory study for Duchenne will be progressing and will now include U.S. sites. We look forward to the future with hope for gene therapy as we strive to improve and extend the lives of those living with Duchenne, a devastating disease,” said CureDuchenne Founder and CEO Debra Miller. 

DMD is the most common form of muscular dystrophy, occurring in approximately 1 in 5,000 male births. Those affected with Duchenne lose their ability to walk, feed themselves, and breathe independently and ultimately succumb to heart failure. For more information, visit: and
