Summary

This trial is testing a new treatment for leukemia that uses the patient's own immune cells. The first part of the trial will test how safe it is, and the second part will test how well it works.

Who is the study for?
This trial is for children and young adults aged 1-35 with relapsed/refractory acute myeloid leukemia (AML) that expresses CD33. Participants must have had at least one failed treatment, be eligible for a stem cell transplant, and have adequate organ function. Pregnant or breastfeeding individuals, those with certain infections or other cancers, and anyone who has recently received specific treatments are excluded.
What is being tested?
The study tests two types of anti-CD33 CAR T-cell therapies: autologous (from the patient's own cells) and allogeneic (donor cells). It aims to find the highest dose patients can tolerate without severe side effects in Phase 1 and then assess how well the treatment works in Phase 2.
What are the potential side effects?
Potential side effects may include immune reactions leading to inflammation in various organs, symptoms related to infusion such as fever or chills, fatigue, blood count abnormalities which could increase infection risk, allergic reactions to components used in cell manufacturing.
