Monitoring CAR‑BCMA immune cells in multiple myeloma

CAR-T Immunomonitoring in Multiple Myeloma

NA · Poitiers University Hospital · NCT07342179

This project will test whether tracking CAR‑BCMA cells and related immune markers in blood and bone marrow can help predict which multiple myeloma patients respond to CAR‑T therapy.

What this trial studies

Researchers will collect clinical data from diagnosis, relapses, prior treatments, and details around CAR‑T therapy, and will take additional blood and bone marrow samples before and up to one year after CAR‑T infusion. Samples will be sent to centralized laboratories to measure CAR‑BCMA cell persistence and the expression of surface proteins CD95 and CD95L as well as soluble CD95L in serum. The project is conducted in collaboration with the IRMETIST INSERM unit at the University of Poitiers and aims to identify cellular immunological markers that correlate with effective responses to CAR‑T treatment. Results will be used to inform patient follow‑up and may guide future personalized immunotherapy approaches.

Who should consider this trial

Good fit: Adults (18+) with a diagnosis of multiple myeloma who are scheduled to receive CAR‑T cell therapy in accordance with French authorizations and who can attend Poitiers for extra blood and bone marrow sampling are ideal candidates.

Not a fit: Patients who are not receiving CAR‑T therapy, who cannot comply with repeated sampling, or who are in excluded vulnerable groups (for example pregnant individuals or those under legal guardianship) are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, this could help doctors predict who is most likely to benefit from CAR‑T therapy and tailor follow‑up or additional treatments accordingly.

How similar studies have performed: Previous work has shown that long‑term persistence of CAR‑T cells often correlates with better outcomes, but using CD95/CD95L profiling as predictive markers is a more novel approach with limited prior validation.
