简要总结
This trial will evaluate safety and efficacy of human engineered T-cell therapies, in participants with advanced tumors.
详细描述
New York esophageal antigen-1 (NY-ESO-1) and LAGE-1a antigens are tumor-associated proteins that have been found in several tumor types. Clinical trials using adoptively transferred T cells directed against NY-ESO-1/LAGE-1a have shown objective responses. Letetresgene autoleucel (lete-cel, GSK3377794) is the first generation of NY-ESO-1 specific T-cell receptor engineered T cells. This is a master protocol investigating T-cell therapies. It will initially consist of a core protocol with two independent substudies investigating Letetresgene autoleucel in previously untreated (1L) Human Leukocyte Antigen (HLA)-A\*02+ participants with NY-ESO-1+ advanced (metastatic or unresectable) synovial sarcoma (SS) or myxoid/round cell liposarcoma (MRCLS) (Substudy 1) and Letetresgene autoleucel as second line or higher (2L+) treatment in HLA-A\*02+ participants with NY-ESO-1+ advanced (metastatic or unresectable) SS or MRCLS who have progressed following treatment with anthracycline based chemotherapy (Substudy 2).

结局指标
主要结局
Substudy 1: Overall response rate (ORR)
时间窗: Until disease progression (up to 5 years)
Overall response rate is defined as the percentage of participants with a confirmed complete response (CR) or partial response (PR) relative to the total number of participants within the analysis population at any time per Response Evaluation Criteria in Solid Tumors (RECIST) version (v) 1.1. as determined by the local investigators.
Substudy 2: Overall response rate (ORR) as assessed by central independent review
时间窗: Up to 5 years
Overall response rate is defined as the percentage of participants with a confirmed CR or PR relative to the total number of participants within the analysis population at any time per RECIST v1.1. as assessed by central independent review.
