Breakthrough Designation for Quest Diagnostic
FDA has granted Quest Diagnostics a breakthrough device designation for its AAVrh74 ELISA assay, an enzyme-linked immunosorbent in vitro diagnostic for the semi-quantitative detection of antibodies (IgG) to AAVrh74 capsid in human serum. The test is intended to be used as an aid to identify patients eligible for treatment with Sarepta Therapeutics’ Elevidys (delandistrogene moxeparvovec-rokl), a gene therapy for patients with Duchenne muscular dystrophy. Quest and Sarepta say they have recently expanded a collaboration under which Quest will develop one or more companion or complementary diagnostics in connection with Sarepta’s portfolio of investigational and approved gene therapies.
