Shares of Sarepta Therapeutics Inc (NASDAQ:SRPT) plunged 10% after the company disclosed that the U.S. Food and Drug Administration (FDA) has imposed a clinical hold on several of its gene therapy programs targeting limb girdle muscular dystrophy (LGMD).

In a major win for Sarepta Therapeutics Inc., US regulators are recommending that patients who can walk be allowed to take its gene therapy Elevidys again.

In its own communique issued shortly after the FDA’s, Sarepta elaborated on the situation and confirmed a Roche statement to Bloomberg News that linked the probe to a fatality in Brazil and held that the death of the patient was unrelated to Elevidys itself.
