Double-Barreled attack: Gene-Edited stem cells and CAR T-Cells take on tough leukemia

NCT ID NCT05945849

First seen Jul 09, 2026 · Last updated Jul 10, 2026 · Updated 1 time

Summary

This trial tests a two-part treatment for people with acute myeloid leukemia (AML) that has not responded to standard therapy. First, patients receive a stem cell transplant from a healthy donor, but the stem cells are gene-edited to hide from the second treatment: specially engineered CAR T-cells designed to seek and destroy leukemia cells. The goal is to make the transplant safer and more effective by protecting healthy bone marrow from the CAR T-cells.

What this could mean

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

Active substance
gene-edited stem cells (CD33KO-HSPC) and CAR T-cells (CART33)
What this could lead to
If successful, this approach could offer a new treatment option for people with hard-to-treat acute myeloid leukemia by making stem cell transplants safer and more effective.
What could go wrong
This is an early phase 1 trial with only 16 participants, so safety and effectiveness are not yet proven. There are risks from the stem cell transplant and CAR T-cell therapy, including serious side effects.
