Summary

This trial will see if human-engineered T-cell therapies are safe and effective in people with advanced tumors.

Who is the study for?
This trial is for people with advanced tumors that test positive for NY-ESO-1. Participants must be at least 10 years old, have a specific performance status, and match certain HLA types. They should have good organ function and measurable disease but no history of severe autoimmune diseases, previous similar treatments, or recent major surgery.
What is being tested?
The trial tests the safety and effectiveness of genetically engineered T-cell therapy (lete-cel) combined with Fludarabine and Cyclophosphamide in treating solid tumors expressing NY-ESO-1 or LAGE-1a. It's designed to see how well these therapies work against advanced cancers.
What are the potential side effects?
Potential side effects may include immune system reactions, infusion-related responses, changes in blood counts leading to increased infection risk or bleeding problems, fatigue, nausea from chemotherapy drugs like Fludarabine and Cyclophosphamide.

Trial Design

2Treatment groups
Experimental Treatment
Group I: Substudy 2: lete-cel in advanced (metastatic or unresectable) SS or MRCLS post anthracycline chemoExperimental Treatment3 Interventions
Eligible participants will be leukapheresed to manufacture engineered T cells. Participants will then receive letetresgene autoleucel.
Group II: Substudy 1: lete-cel in previously untreated advanced (metastatic or unresectable) SS or MRCLSExperimental Treatment3 Interventions
Eligible participants will be leukapheresed to manufacture engineered T cells. Participants will then receive letetresgene autoleucel.
