Brief Summary

This trial will evaluate safety and efficacy of human engineered T-cell therapies, in participants with advanced tumors. This trial is a sub study of the Master study NCT03967223.

Eligibility Criteria

Inclusion

  • Participant must be greater than or equal to 10 years of age on the day of signing informed consent.
  • Participant scheduled to receive clinical drug product supply must also weigh ≥40 kg
  • Participant must be positive for HLA-A\*02:01, HLA-A\*02:05, and/or HLA-A\*02:06 alleles by a designated central laboratory
  • Participant's tumor is positive for NY-ESO-1 expression by a designated central laboratory.
  • Participant has a diagnosis of synovial sarcoma (SS) or myxoid/round cell liposarcoma (MRCLS)
  • Performance status: dependent on age - Lansky \> 60, Karnofsky \> 60, Eastern
  • Cooperative Oncology Group 0-1.
  • Participant must have adequate organ function and blood cell counts, within 7 days prior to leukapheresis.
  • At time of treatment, participant has measurable disease according to RECIST v1.1.
  • Male or female. Contraception requirements will apply at the time of leukapheresis and treatment.
  • Consultation for prior history per protocol specifications.

Exclusion

  • Central nervous system metastases.
  • Any other prior malignancy that is not in complete remission.
  • Clinically significant systemic illness (.(Serious active infections or significant cardiac, pulmonary, hepatic or other organ dysfunction, that in the judgment of the Investigator would compromise the participant's ability to tolerate protocol therapy or significantly increase the risk of complications)
  • Prior or active demyelinating disease.
  • History of chronic or recurrent (within the last year prior to leukapheresis) severe autoimmune or immune mediated disease (e.g. Crohn's disease, systemic lupus) requiring steroids or other immunosuppressive treatments.
  • Previous treatment with genetically engineered NY-ESO-1-specific T cells.
  • Previous NY-ESO-1 vaccine or NY-ESO-1 targeting antibody.
  • Prior gene therapy using an integrating vector.
  • Previous allogeneic hematopoietic stem cell transplant.
  • Washout periods for prior radiotherapy and systemic chemotherapy must be followed.
  • Participant had major surgery in less than or equal to 28 days of first dose of study intervention.
  • Prior radiation exceeds protocol specified limits.
