Brief Title  ICMJE Master Protocol to Assess Safety and Dose of First Time in Human Next Generation Engineered T Cells in NY-ESO-1 and/or LAGE-1a Positive Advanced Solid Tumors
Official Title  ICMJE Master Protocol to Assess the Safety and Recommended Phase 2 Dose of Next Generations of Autologous Enhanced NY-ESO-1/ LAGE-1a TCR Engineered T-cells, Alone or in Combination With Other Agents, in Participants With Advanced Tumors
Brief Summary This trial will evaluate the safety and efficacy of first time in human engineered T-cell therapies, in participants with advanced tumors.
Detailed Description 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 have shown objective responses. GSK3901961, GSK3845097 and GSK4427296 are next generation engineered T-cell receptor (TCR) T-cells, co-expressing the cluster of differentiation 8 (CD8) alpha cell surface receptor, targeting NY-ESO-1, co-expressing the dominant-negative TGF-beta receptor type II (dnTGF-beta RII) cell surface receptor, targeting NY-ESO-1, and engineered using the Epigenetically Reprogrammed (Epi-R) manufacturing process, respectively to potentially improve function. This is a master protocol evaluating first time in human T-cell therapies. It currently consists of three independent substudies, investigating GSK3901961, GSK3845097 and GSK4427296 in human leukocyte antigen (HLA)-A*02 positive participants with NYESO1+ previously treated advanced (metastatic or unresectable) synovial sarcoma (SS)/myxoid/round cell liposarcoma (MRCLS) and/or previously treated metastatic non-small cell lung cancer (NSCLC).
