AGC Biologics Announces U.S. and EU Marketing Authorization for Gene Therapy Waskyra Contract-Manufactured by Its Milan Facility

AGC Biologics S.p.A. (headquartered in Milan, Italy; hereinafter “AGC Biologics”), the biopharmaceutical CDMO*1 subsidiary of AGC Inc. (headquartered in Tokyo; President: Yoshinori Hirai), announces that the ex vivo gene therapy Waskyra, which it contract-manufactured, has received marketing authorization from the U.S. Food and Drug Administration (FDA) and the European Commission. Developed by Fondazione Telethon*2, an Italian government-recognized non-profit biomedical research organization, Waskyra is indicated for Wiskott-Aldrich syndrome, a rare immune disorder. This approval enables patients to access a new treatment option.

Wiskott-Aldrich syndrome is a rare immune disorder affecting approximately one in 250,000 live male births. Until now, treatment options have primarily consisted of symptomatic therapies and hematopoietic stem cell transplants from family donors. Waskyra is an ex vivo gene therapy that uses the patient’s own cells to correct the underlying genetic defect, avoiding donor dependency and the risk of rejection, while aiming for a curative outcome with minimal burden.

For this approval, AGC Biologics leveraged its global top-class experience in process development and contract manufacturing of gene and cell therapies*3, providing comprehensive support for lentiviral vector*4 production, patient-specific genetically modified cell manufacturing, and regulatory compliance, assisting with regulatory filings at every step. AGC Biologics will continue to provide support toward commercial manufacturing.

AGC Group’s medium-term management plan, AGC plus-2026, defines three social values. Among them, “Well-being” focuses on contributing to safe, secure, and healthy living by ensuring a stable supply of essential products and services for daily life and healthcare. Through its Life Science business, AGC continues to deliver globally unified, high-quality CDMO services for pharmaceuticals and agrochemicals, maximizing synergies across sites to benefit society.
