Allison Betof Warner, MD, Stanford Medicine, Stanford, CA, and Ben Creelan, MD, H. Lee Moffitt Cancer Center & Research Institute, Tampa, FL, discuss the evolving landscape of tumor-infiltrating lymphocytes (TILs) and other cell therapies across solid tumors, focusing on melanoma and lung cancer. The rountable highlights genetically edited TILs, membrane-bound IL-15, TCRs, and CARs. They explore efforts to reduce IL-2-related toxicity, challenges of HLA loss, and the promise of one-time therapies over ongoing bispecific antibody treatments. Key targets include PRAME, DL3, GPC3, and p53. The experts emphasize the importance of achieving durable responses and using cell therapies as consolidation following first-line treatment. They also touch on the future of minimal residual disease (MRD)-guided therapies and the need for better assays in solid tumors. This discussion took place at the 7th International Workshop on CAR-T and bispecifics (iwCAR-T) 2025 held in Miami, FL.
