August 8, 2024- Thermo Fisher Scientific Inc. announced that itsSeCore™ CDx HLA A Sequencing System has been granted 510(k) clearance by the United States Food and Drug Administration (FDA) for use as a companion diagnostic with TECELRA® (afamitresgene autoleucel), Adaptimmune’s newly approved T-cell receptor (TCR) therapy 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 tumor expresses the MAGE-A4 antigen as determined by FDA-approved or cleared companion diagnostic devices. Synovial sarcoma is a rare, soft tissue cancer that most commonly impacts young adults.
Cancer immunotherapies, including TCR therapies, have become increasingly powerful tools in cancer treatment, particularly for patients with metastatic or unresectable tumors. TCRs interact with specific human leukocyte antigen (HLA) proteins to activate an immune response, making high-resolution HLA typing a critical step in identifying patients most likely to benefit from engineered TCR T-cell therapies like TECELRA.
