Suicide Gene-Equipped t cells aim to make stem cell transplants safer

NCT ID NCT01494103

First seen Jul 01, 2026 · Last updated Jul 01, 2026

Summary

This trial tests whether specially modified T cells from a partially matched donor can help patients recover their immune system faster after a stem cell transplant. The T cells are engineered with a 'suicide gene' that allows doctors to destroy them if they cause graft-versus-host disease (GvHD), a serious complication. The study enrolls people with blood cancers or immune disorders who lack a perfectly matched donor. The goal is to find a safe dose of these cells and see if they improve immune recovery without causing severe GvHD.

What this could mean

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

Active substance

iCaspase9-transduced T cells and AP1903

What this could lead to

If it works, this approach could help patients recover their immune system faster after a stem cell transplant while providing a safety switch to stop dangerous graft-versus-host disease.

What could go wrong

This is an early-phase trial with only 15 participants, so results may not apply broadly. The suicide gene may not activate fully, or the modified cells could cause unexpected side effects.
