Lyell Immunopharma Inc. has announced positive new clinical data from a multi-center Phase 1/2 trial of its LYL314 treatment for aggressive large B-cell lymphoma. The trial demonstrated an 88% overall response rate and a 72% complete response rate in patients treated in the third- or later-line setting. Among those achieving a complete response, 71% remained in complete response for at least six months. The treatment, LYL314, is an autologous dual-targeting CD19/CD20 chimeric antigen receptor $(CAR)$ T-cell product candidate with Regenerative Medicine Advanced Therapy (RMAT) and Fast Track designations from the FDA, aimed at relapsed and/or refractory large B-cell lymphoma. A pivotal single-arm PiNACLE trial is currently underway in CAR T-naïve patients. The clinical data will be presented on June 18, 2025, at the International Conference on Malignant Lymphoma in Lugano, Switzerland.
