Summary

This trial is testing a new drug, VOR33, on people with AML who are having a HCT.

Who is the study for?
This trial is for adults aged 18-70 with CD33+ AML who are candidates for a stem cell transplant from a perfectly matched donor. They should be in remission or have low blast counts, unless approved by the medical monitor. Participants need good heart, lung, kidney, and liver function but can't join if they've had certain other cancers, prior Mylotarg treatment, specific genetic abnormalities related to leukemia, or uncontrolled infections.
What is being tested?
The study tests VOR33-engineered stem cells lacking CD33 protein followed by Mylotarg post-transplant in patients with AML. It's an early-phase trial to see how safe it is and how well it works when given during a standard HLA-matched allogeneic hematopoietic cell transplant.
What are the potential side effects?
Potential side effects include those typical of stem cell transplants such as infection risk due to immune suppression and reactions related to graft-versus-host disease. Mylotarg may cause liver problems (including severe), infusion-related reactions, bleeding issues, and could potentially harm normal blood-forming cells.
