Aug 24 (Reuters) – Capricor Therapeutics said on Monday that the U.S. Food and Drug ​Administration had extended the ‌review of its experimental cell therapy for Duchenne muscular dystrophy by three months.

Shares of the company surged ‌over ​20% in ⁠early morning trading, as ⁠the update boosted market sentiment after a setback last month when an FDA advisory ​panel voted nine-to-three against the effectiveness data of the ⁠drug.

The health regulator ⁠set the deadline to ​November 22 to allow more ​time to review new clinical trial ‌data submitted by the company.

Capricor’s therapy, called deramiocel, aims to treat Duchenne, a rare ⁠and progressive genetic disease that causes muscle wasting and mostly affects boys.

“With ⁠an ‌additional year of follow-up ⁠from HOPE-3, we now ​have ‌one of the most ​extensive ⁠clinical datasets evaluating upper limb function in Duchenne,” said Capricor CEO Linda Marbán.
