Summary: The main purpose of this trial is to evaluate the efficacy and safety of TAEST16001 cells in the treatment of advanced soft tissue sarcoma patients with HLA-A*02:01 tissue genotype and positive tumor antigen NY-ESO-1 expression.

Detailed description: This is a single-arm, open label, multi-center, phase II study. The investigators include advanced soft tissue sarcoma with failure in standard treatment or no recommended standard therapy. TCR-T cell therapy has made a breakthrough for tumors in recent years. Phase I/II trial of NY-ESO-1-specific TCR-T treatment for synovial sarcoma and melanoma, conducted by the Rosenberg team at the National Cancer Institute, showed that 61% Synovial cell sarcoma patients and 55% melanoma patients benefit from this treatment, without severe side effects found in T cell receptor (TCR) transduced T-Cell Immunotherapy. This clinical trial is mainly focused on cancer-testis antigen, because it is not expressed in normal cells. NY-ESO-1 antigen as one member of cancer-testis antigen, is commonly expressed in 10-50% of melanoma, lung, liver, esophageal, breast, prostate, bladder, thyroid and ovarian cancer cases, 60% of multiple myeloma cases, and 70-80% of synovial sarcoma. NY-ESO-1 expression was also found in 88.2% of myxoid liposarcomas, 61.1% of synovial sarcomas, 31.3% of osteosarcomas, 21.4% of pleomorphic liposarcomas, 16.7% of desmoplastic small round cell tumors, and 14.3% of chondrosarcomas. Although the NY-ESO-1 TCR cell therapy for synovial sarcoma and melanoma has benefited many patients and the phase I trial has been performed, its effect and safety on advanced soft tissue sarcoma is still unknown. The patients must meet the two criteria: HLA-A*0201positive and NY-ESO-1 positive cells≥20% by immunohistochemistry.
