“We are very excited Mallinckrodt has chosen to study how this investigational drug, MNK-1411, might help in treating Duchenne Muscular Dystrophy,” said Pat Furlong, President and CEO, Parent Project Muscular Dystrophy. “In the fight to end Duchenne Muscular Dystrophy, our community welcomes partners dedicated to this goal.”

The company also announced that MNK-1411 recently received the European Medicines Agency (EMA) Orphan Medicinal Product designation for the potential treatment of Duchenne Muscular Dystrophy.

“Mallinckrodt is focused on meeting the unmet medical needs of patients, particularly those with rare diseases like DMD,” said Steven Romano, MD, Executive Vice President and Chief Scientific Officer at Mallinckrodt. “We are pleased to enroll the first patient in our Phase 2 clinical trial of investigational drug MNK-1411 in boys with DMD.

About the Clinical Trial
The Phase 2 clinical study is entitled: A Multicenter, Randomized, Parallel Group, Double Blind, Multiple Dose, Placebo Controlled Study to Assess the Efficacy and Safety of MNK-1411 in Male Subjects 4 to 8 Years of Age With Duchenne Muscular Dystrophy (the BRAVE study). The study will include patients who have a diagnosis of DMD confirmed by complete dystrophin deficiency, or an identifiable mutation in the DMD gene, or complete dystrophin gene sequencing consistent with DMD; patients must also have a typical clinical profile consistent with DMD to be included.

Approximately 130 patients who meet eligibility criteria will be randomly assigned in a 2:1 ratio to receive one of two weight-based doses of MNK-1411, or they will receive volume-matched placebo, administered subcutaneously 2 times/week for 24 weeks. Study subjects who complete the 24-week randomized, double-blind, placebo-controlled treatment period will be eligible to receive active treatment for an additional 24 weeks during an optional open-label extension. Key efficacy outcome measures for the study will include timed function tests, such as a 10-meter walk/run, 4-stair climb and rise from floor, and the NorthStar Ambulatory Assessment.
