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 in previously untreated (1L) Human Leukocyte Antigen (HLA)-A02+ 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-A02+ participants with NY-ESO-1+ advanced (metastatic or unresectable) SS or MRCLS who have progressed following treatment with anthracycline based chemotherapy (Substudy 2).

Outcome Measures
Primary Outcome Measures
- Substudy 1: Overall response rate (ORR) [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 [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.
Secondary Outcome Measures
- Substudy 1 and 2: Time to response (TTR) [Until disease progression (up to 5 years)]
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.
- Substudy 1 and 2: Duration of response (DOR) [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.
- Substudy 1 and 2: Disease control rate (DCR) [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.
- Substudy 1 and 2: Progression free survival (PFS) [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.
- Substudy 1 and 2: Frequency of adverse events (AEs), serious adverse events (SAEs) and AEs of special interest (AESI) according to severity [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.
- Substudy 1 and 2: Number of participants with replication competent lentivirus (RCL) [Until disease progression (up to 5 years)]
RCL exposure will be assessed by polymerase chain reaction (PCR) based assay.
- Substudy 1 and 2: Number of participants with insertional oncogenesis (IO) [Until disease progression (up to 5 years)]
Peripheral blood mononuclear cells (PBMC) samples will be collected for monitoring insertional oncogenesis by PCR for gene modified cells in the blood.
- Substudy 2: Number of participants with clinically significant changes in hematology, clinical chemistry and urinalysis parameters [Until disease progression (up to 5 years)]
Blood and urine samples will be collected for assessment of hematology, clinical chemistry and urinalysis parameters.
- Substudy 1 and 2: Maximum transgene expansion (Cmax) of letetresgene autoleucel [Until disease progression (up to 5 years)]
Whole blood samples will be collected at indicated time points for evaluation of Cmax.
- Substudy 1 and 2: Time to Cmax (Tmax) of letetresgene autoleucel [Until disease progression (up to 5 years)]
Whole blood samples will be collected at indicated time points for evaluation of Tmax.
- Substudy 1 and 2: Area under the concentration/persistence time curve from zero to time t (AUC[0-t]) of letetresgene autoleucel [Until disease progression (up to 5 years)]
Whole blood samples will be collected at indicated time points for evaluation of AUC(0-t).
- Substudy 2: Overall response rate (ORR) as determined by the local investigators [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 determined by the local investigators.
- Substudy 2: Overall Survival (OS) [Up to 5 years]
Overall Survival is defined as the interval of time between the date of T-cell infusion and the date of death.
- Substudy 2: Number of participants with positive anti-drug antibodies (ADA) and titers of ADA against letetresgene autoleucel [Up to 36 months]
Serum samples will be collected to analyze for the presence of ADAs using validated immunoassays.
