Study summary

The primary purpose of this sub study is to assess the safety, tolerability and determine recommended Phase 2 dose (RP2D) of GSK3901961 in HLA A\*02:01, HLA-A\*02:05 and/or HLA A\*02:06 positive participants with New York esophageal squamous cell carcinoma (NY ESO 1) and/or Cancer testis antigen 2 (LAGE 1a) positive previously treated metastatic Non-Small Cell Lung Cancer (NSCLC) and previously treated, advanced (metastatic or unresectable) Synovial Sarcoma/ Myxoid/Round Cell Liposarcoma SS/MRCLS.

Who may be able to participate

The sponsor separates these requirements into two groups. You do not need to interpret them alone—use them to guide a conversation with the study team.

Requirements people may need to meetInclusion 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.
  • 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
  • Participant has histologically or cytologically confirmed Stage IV NSCLC
  • Participant has been previously treated with SOC for Stage IV NSCLC
Reasons someone may not be able to joinExclusion 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
