ClinConnect Summary
This clinical trial is studying a new treatment approach for patients with relapsed or refractory acute myeloid leukemia (AML), a type of blood cancer. The researchers want to see if a combination of low-dose total body irradiation (TBI) and medications called busulfan (BU) and melphalan (MEL) can improve the success of stem cell transplants. This treatment aims to help more patients achieve a deeper remission, reduce the chances of the cancer coming back, and lessen the risk of complications from the transplant.
To participate in this study, patients need to be between 14 and 70 years old and have been diagnosed with relapsed or refractory AML. They must have a suitable donor for the stem cell transplant and meet certain health criteria, like having normal heart and liver function. Participants will undergo the new treatment regimen and will be monitored closely for safety and how well the treatment works. It’s important to know that this trial is currently recruiting, so eligible patients who are interested can learn more about how to join.
