Afamitresgene Autoleucel: First Approval.

Afamitresgene autoleucel (TECELRA ^® ), a genetically modified human leukocyte antigen (HLA)-restricted autologous melanoma-associated antigen 4 (MAGE-A4)-directed T cell immunotherapy, is being developed by Adaptimmune Therapeutics plc, for the treatment of solid tumours expressing the MAGE-A4 antigen. In August 2024, afamitresgene autoleucel was approved in the USA under accelerated approval for the treatment of adults with unresectable or metastatic synovial sarcoma who have received prior chemotherapy, are HLA-A*02:01P, -A*02:02P, -A*02:03P or -A*02:06P positive and whose tumour expresses the MAGE-A4 antigen as determined by FDA-approved or cleared companion diagnostic devices. This article summarizes the milestones in the development of afamitresgene autoleucel leading to this first approval for the treatment of advanced synovial sarcoma.
