Stem cells may supercharge CAR t for tough blood cancers

NCT ID NCT05887167

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This early-phase trial is testing whether adding a patient's own blood stem cells to standard CAR T-cell therapy is safe and doable for people with relapsed or refractory blood cancers like lymphoma, leukemia, and myeloma. Twenty participants will receive their own stem cells 10 days after CAR T infusion. The main goals are to see if enough stem cells can be collected and to monitor side effects like cytokine release syndrome and nerve toxicity.

What this could mean

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

Active substance

autologous hematopoietic stem cells (aHSCs) combined with FDA-approved CAR T-cell therapy

What this could lead to

If successful, this approach could make CAR T therapy safer and more effective for patients with hard-to-treat blood cancers.

What could go wrong

This is a very early phase 1 trial with only 20 participants, so results may not apply broadly. Adding stem cells could also increase risks like graft-versus-host disease or other complications.
