The FDA in its May 2023 Advisory Committee Briefing Document, provided helpful insights into its safety review of filings for AAV vector-based gene therapy products. The Briefing Document was for Sarepta’s SRP-9001 (delandistrogene moxeparvovec) gene therapy for Duchene muscular dystrophy (DMD) (FIG. 1). This FDA insight is helpful information for sponsors as well as vendors whose tools address these issues. The FDA cited 3 types of safety issues (FIG. 1):
1) Hepatoxicity
2) Thrombotic microangiopathies
3) Oncogenicity due to integration and insertional mutagenesis
