Prophylaxis CTLA4-ig reduces anti-AAV neutralizing antibodies in AAV gene therapy for hemophilia (ASH 2025) - P=N/A, P1 | "Abatacept(CTLA4-Ig, 5 mg/kg) or an equivalent PBS was administered intraperitoneally 3 days prior to vectorinfusion, followed by twice-weekly maintenance dosing for 6 weeks...Prophylaxis CTLA4-Ig (5 mg/kg) was administered3 days prior to AAV vector (BBM-H803) infusion... Prophylaxis administration of CTLA4-Ig effectively suppresses anti-AAV Nab formationfollowing AAV gene therapy in hemophilia A patients, creating a potential immunological tolerancewindow for re-treatment."
