Company Update (NASDAQ:SRPT): Sarepta Therapeutics Inc Announces First Patient Dosed in Phase III Clinical Trial of SRP-4045 and SRP-4053

SRPTSarepta Therapeutics Inc (NASDAQ:SRPT) announced the first patient dosed in the phase III clinical trial of SRP-4045 and SRP-4053 in patients with Duchenne muscular dystrophy amenable to exon 45 or 53 skipping.

“We are excited to announce the first patient dosed in our ESSENCE trial of SRP-4045 and SRP-4053, for DMD patients amenable to Exon 45 and 53 skipping “ said Edward Kaye, Sarepta’s chief executive officer. “It is our goal to treat as many patients amenable to exon skipping as possible, and therefore is important to advance our clinical pipeline candidates. We have made great effort to develop a meaningful clinical trial, using our learnings from our previous clinical programs and observations of the natural history of Duchenne.”

The Phase III study, ESSENCE, is a double-blind, placebo-controlled, multi-center study to evaluate the efficacy and safety of SRP-4045 and SRP-4053. Eligible patients with out-of-frame deletion mutations amenable to exon 45 or 53 skipping will be randomized to receive once weekly intravenous (IV) infusions of 30 mg/kg SRP-4045 or 30 mg/kg SRP-4053 respectively (combined-active group, 66 patients) or placebo (33 patients) for up to 96 weeks (the placebo-controlled period of the trial). This will be followed by an open label extension period in which all patients will receive open-label active treatment for up to 96 weeks.

The study will enroll approximately 99 patients aged 7 to 13 years, inclusive, with a minimum target of 45 patients amenable to exon 45 skipping and 45 patients amenable to exon 53 skipping.

Twice as many patients will receive active treatment as will receive placebo. Approximately 66 patients will be randomized to receive active treatment with either SRP-4045 or SRP-4053 (depending on deletion mutation), and 33 patients will be randomized to receive placebo. (Original Source)
