- Substudy 1, 2 and 3: Frequency of dose limiting toxicities (DLTs) [ Time Frame: Until disease progression (up to 4 years) ]Toxicities will be considered DLTs if they are considered at least possibly related to transduced T-cells; and they occur within the DLT-assessment period.
- Substudy 1, 2 and 3: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 4 years) ]AEs, SAEs and AESIs will be collected. Severity of AEs and SAEs will be summarized using NCI-CTCAE, version 5.0.
- Substudy 1, 2 and 3: Overall response rate (ORR) [ Time Frame: Until disease progression (up to 4 years) ]Overall response rate is defined as the percentage of participants with a confirmed complete response (CR) or a confirmed partial response (PR) relative to the total number of participants within the relevant cohort and analysis population at any time per Response evaluation criteria in solid tumors (RECIST) version 1.1 as determined by the local investigators.
- Substudy 1, 2 and 3: Duration of response (DOR) [ Time Frame: Until disease progression (up to 4 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, 2 and 3: Maximum expansion/persistence (Cmax) [ Time Frame: Until disease progression (up to 4 years) ]Whole blood samples will be collected at indicated time points for evaluation of Cmax.
- Substudy 1, 2 and 3 : Time to Cmax (Tmax) [ Time Frame: Until disease progression (up to 4 years) ]Whole blood samples will be collected at indicated time points for evaluation of Tmax.
- Substudy 1, 2 and 3: Area under the concentration/persistence time curve from zero to time t (AUC[0-t]) [ Time Frame: Until disease progression (up to 4 years) ]Whole blood samples will be collected at indicated time points for evaluation of AUC (0 to t).

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Eligibility Criteria:
Inclusion criteria:
- Participant must be >=18 years of age and weighs ≥40 kg on the day of signing informed consent
- Participant must be positive for HLA-A*02:01, HLA-A*02:05, and/or HLA-A*02:06 alleles
- Participant's tumor must have tested positive for NY-ESO-1 and/or LAGE-1a expression by a GSK designated laboratory
- Performance status: Eastern Cooperative Oncology Group of 0-1
- Participant must have adequate organ function and blood cell counts 7 days prior to leukapheresis
- Participant must have measurable disease according to RECIST v1.1.
Additional criteria for participants with SS/ MRCLS:
- Participant has advanced (metastatic or unresectable) SS or MRCLS confirmed by local histopathology with evidence of disease-specific translocation
- Participant has completed at least one standard of care (SOC) treatment including anthracycline containing regimen unless intolerant to or ineligible to receive the therapy. Participants who are not candidates to receive anthracycline should have received ifosfamide unless also intolerant to or ineligible to receive ifosfamide. Participants who received neoadjuvant/adjuvant anthracycline or ifosfamide based therapy and progressed will be eligible
Additional criteria for participants with non-small cell lung cancer (NSCLC):
- Participant has Stage IV NSCLC as confirmed by histology or cytology
- Prior therapies for participants lacking actionable genetic aberrations (i.e., wild type), per National Comprehensive Cancer Network (NCCN) guidelines: participant has been previously treated with or is intolerant to programmed death receptor-1 (PD)-1/Programmed death ligand 1 (PD-L1) checkpoint blockade therapy and has been previously treated with or is intolerant to a platinum-based chemotherapy. Adjuvant therapy will count as a regimen if completed within 6 months before relapse. Or for participants that harbors an actionable genetic aberration (e.g. BRAF, anaplastic lymphoma kinase [ALK]/ c-ros oncogene 1 [ROS1] etc.), per NCCN guidelines: participants has been previously treated with or is intolerant to SOC therapy, including targeted therapy, as recommended by NCCN or equivalent country-level guidelines (European Society for Medical Oncology [ESMO], National Institute for Health & Care Excellence [NICE]) . Or Investigator has decided that additional lines of SOC therapy after the first line are not in the participant's best interest.
Exclusion criteria:
- Central nervous system (CNS) metastases, with certain exceptions for CNS metastases in NSCLC as specified in the protocol
- Any other prior malignancy that is not in complete remission
- Clinically significant systemic illness
- Prior or active demyelinating disease
- History of chronic or recurrent (within the last year prior to leukapheresis) severe autoimmune or immune mediated disease requiring steroids or other immunosuppressive treatments
- Previous treatment with genetically engineered NY-ESO-1-specific T cells, NY-ESO-1 vaccine or NY-ESO-1 targeting antibody
- Prior gene therapy using an integrating vector
- Previous allogeneic hematopoietic stem cell transplant within the last 5 years or solid organ transplant
- Washout periods for prior radiotherapy and systemic chemotherapy must be followed
- Major surgery within 4 weeks prior to lymphodepletion
- Pregnant or breastfeeding females
