Marathon Pharma Files NDA for Duchenne Drug
Marathon Pharmaceuticals has submitted an NDA for the investigational drug deflazacort for treating patients with Duchenne muscular dystrophy (DMD), the most common and most severe form of muscular dystrophy. The submission is supported by preclinical and clinical study data, including two pivotal clinical efficacy trials exclusively licensed by Marathon in more than 200 Duchenne patients aged five to 15 years.
“These data show that deflazacort improved muscle strength and other functional outcomes in patients with Duchenne regardless of genetic etiology and in one of the studies ambulation status,” the company says. Marathon additionally conducted seven clinical pharmacology and safety studies of deflazacort and nine preclinical studies to support either the initiation of clinical studies or marketing approval.
An expanded access program, Access DMD, is ongoing in the U.S. and provides deflazacort to patients with Duchenne free of charge during the NDA review process.
