MD Anderson Study Identifies Three B-Cell Lymphoma Subgroups with Distinct CD19 CAR-T Response Patterns
- Researchers at MD Anderson Cancer Center analyzed 232 patients with large B-cell lymphoma to identify three distinct tumor microenvironment subgroups with different responses to CD19 CAR-T therapy.
- The study profiled over 1.8 million cells and validated findings using ZUMA-7 Phase III trial data, revealing that the lymph node subgroup benefits most from CAR-T therapy while the T cell exhausted group shows no significant benefit.
- The findings provide a precision medicine framework to guide treatment selection and identify patients who may need alternative therapeutic approaches beyond CAR-T cell therapy.
- The research opens opportunities for targeted therapies in development to address the needs of patients in subgroups with poorer CAR-T outcomes.
