(Reuters) -Sarepta Therapeutics shares surged more than 30% before the bell on Tuesday, as analysts said the resumption of U.S. shipments for its muscular gene therapy partially removes financial headwinds and decreases the risk of market withdrawal.

The swift FDA action removes an overhang from Sarepta and allows Elevidys to return to the market without another safety study, as had been feared, Jefferies analysts said Monday.

On Monday, the FDA said Sarepta may resume treating ambulatory Duchenne patients with Elevidys. The recommendation comes just 10 days after the agency requested that the company halt all shipments of the one-time treatment following reports of three deaths among patients who had received a Sarepta gene therapy, including two on Elevidys.
