New infusion strategy aims to keep CAR t cells fighting leukemia longer
NCT ID NCT03186118
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This pilot study tests whether giving special immune cells called T-APCs after CAR T cell therapy can help the CAR T cells persist longer in the body and prevent leukemia from returning. It involves 30 children and young adults with relapsed or refractory CD19+ leukemia who have already achieved remission with CAR T cells. The main goals are to check safety and see if the approach is feasible.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
T-cell Antigen Presenting Cells expressing truncated CD19 (T-APCs)
What this could lead to
If it works, this could help CAR T cells stay active longer and reduce the chance of leukemia coming back after treatment.
What could go wrong
This is a very early, small pilot study (Phase 1) focused on safety and feasibility. It may not show clear benefit, and there are risks of side effects from the infusions.
