Summary

This trial is testing whether a new treatment can help people with relapsed or refractory leukemia by increasing the speed of immune system recovery after a stem cell transplant.

Who is the study for?
This trial is for children and adults with blood cancers who need a stem cell transplant but don't have a perfect donor match. They should be in at least their second complete remission or have low levels of remaining cancer cells. Participants must be fit enough for the transplant, with good organ function and performance status.
What is being tested?
The study tests SMART101 injections to speed up immune recovery after a T-cell depleted stem cell transplant in patients with blood cancers. It aims to determine how safe and effective these cultured human T lymphoid progenitors are post-transplant.
What are the potential side effects?
While specific side effects aren't listed, potential risks may include reactions at the injection site, immune system complications, or issues related to rapid immune reconstitution following transplantation.
