Brief Summary:
This trial will evaluate safety and efficacy of human engineered T-cell therapies, in participants with advanced tumors.

Condition or disease Intervention/treatment Phase
Neoplasms Drug: Letetresgene autoleucel (lete-cel, GSK3377794) Drug: Fludarabine Drug: Cyclophosphamide Phase 2

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/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 (lete-cel) 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).

    Time to response is defined as time from date of T-cell administration to first documented evidence of confirmed (CR or PR) as assessed by local investigators per RECIST v1.1.

  2. Substudy 1 and 2: Duration of response (DOR) [ Time Frame: Until disease progression (up to 5 years) ]
    Duration of response is defined as, in the subset of participants who show a confirmed CR or PR as assessed by local investigators, the time from first documented evidence of CR or PR until the first documented sign of disease progression or death.

  3. Substudy 1 and 2: Disease control rate (DCR) [ Time Frame: Until disease progression (up to 5 years) ]
    Disease control rate is defined as the percentage of participants with a confirmed CR, PR, or stable disease (SD) with minimal 12 weeks duration relative to the total number of participants within the analysis population at the time of primary analysis as determined by Investigators per RECIST v1.1.

  4. Substudy 1 and 2: Progression free survival (PFS) [ Time Frame: Until disease progression (up to 5 years) ]
    Progression free survival is defined as the time from the date of T-cell administration until first documented sign of disease progression per RECIST v1.1, or death.

  5. Substudy 1 and 2: Frequency of adverse events (AEs), serious adverse events (SAEs) and AEs of special interest (AESI) according to severity [ Time Frame: Until disease progression (up to 5 years) ]
    AEs, SAEs and AESIs will be collected. Severity of AEs and SAEs will be summarized using National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE), version 5.0.

  6. Substudy 1 and 2: Number of participants with replication competent lentivirus (RCL) [ Time Frame: Until disease progression (up to 5 years) ]
