Preexisting antibody assays for gene therapy: Considerations on patient selection cutoffs and companion diagnostic requirements
20 Feb 2024
Abstract excerpt
Recombinant adeno-associated virus (AAV) vectors are the leading delivery vehicle used for in vivo gene therapies. Anti-AAV antibodies (AAV Abs) can interact with the viral capsid component of an AAV-based gene therapy (GT). Therefore, patients with preexisting AAV Abs (seropositive patients) are often excluded from GT trials to prevent treatment of patients who are unlikely to benefit 1 or may have a higher risk...
