Roche (OTCQX:RHHBY) has decided to pause overseas shipments of Elevidys gene therapy developed by Sarepta Therapeutics (NASDAQ:SRPT) following safety concerns raised in the U.S., Reuters reported, citing a company statement.

Roche Holding AG has temporarily halted shipments of the gene therapy Elevidys in some countries outside the U.S. following a similar move by U.S. partner Sarepta Therapeutics. The decision comes after the FDA requested a pause following the death of a patient undergoing the treatment.

The company refused the FDA’s request and will continue shipping its therapy, Elevidys, to Duchenne patients who can still walk. A pause on shipments to older, non-ambulatory patients remains in place.
