First seen Nov 06, 2025 · Last updated Jun 14, 2026 · Updated 31 times

Summary

This early-phase study tests whether giving radiation therapy before standard CAR T cell treatment is safe and practical for people with B-cell lymphoma that has come back or not responded to prior treatments. About 20 participants will receive split-course bridging radiation to all active disease spots before getting their CAR T cells. The main goal is to check for unexpected severe side effects and see if completing the radiation plan is feasible.
