Can a One-Two punch of CAR-T and lenalidomide beat tough leukemia?
NCT ID NCT06762431
First seen Aug 10, 2026 · Last updated Aug 14, 2026 · Updated 3 times
Summary
This trial is testing whether combining anti-CD19 CAR-T cell therapy with the drug lenalidomide can safely and effectively treat adults with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) that has returned or not responded to prior treatments. Participants will receive CAR-T cells along with lenalidomide, and some will also get obinutuzumab. The goal is to see if this combination can produce lasting remissions and improve outcomes for people with this hard-to-treat blood cancer.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Anti-CD19 CAR T-cell therapy combined with lenalidomide (and obinutuzumab in some cycles)
- What this could lead to
- If successful, this combination could offer a durable, treatment-free remission for people with relapsed or refractory CLL, potentially a cure.
- What could go wrong
- This is an early-phase trial with a small number of patients, so results may not hold up. CAR-T therapy carries risks like severe immune reactions, infections, and prolonged low blood counts.
