Double-Barreled CAR t attack shows promise for tough childhood leukemia

NCT ID NCT05674175

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 2 times

Summary

This study tests a new approach for children and young adults with B-cell acute lymphoblastic leukemia (B-ALL) that has come back or not responded to treatment. It combines two types of engineered immune cells (CAR T cells) that target different markers on cancer cells (CD19 and CD22). The goal is to see if this dual attack is safe and effective, especially for patients who have already tried other cell therapies. About 93 participants will be enrolled.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Two types of engineered immune cells: anti-CD22 CAR T cells and anti-CD19 CAR T cells
What this could lead to
If successful, this could offer a more effective treatment option for children with hard-to-treat B-ALL, potentially leading to longer remissions.
What could go wrong
This is an early-phase trial (Phase 1/2) with a small number of participants. CAR T cell therapy can cause severe side effects like cytokine release syndrome. It may not work for everyone, and long-term effects are unknown.
