Summary

This trial is testing the combination of the immunotherapy drug pembrolizumab with the drugs decitabine and venetoclax, to see if it is safe and effective in treating patients with newly-diagnosed, recurrent, or refractory acute myeloid leukemia or myelodysplastic syndrome.

Who is the study for?
This trial is for adults with newly-diagnosed, recurrent, or treatment-resistant acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS). Participants must be in good physical condition (ECOG status <=1), have a life expectancy of at least 3 months, and cannot be candidates for stem cell transplantation within the next 90 days. They should not have had certain previous treatments that were unsuccessful and must agree to use effective contraception.
What is being tested?
The trial is testing the safety and optimal dosage of pembrolizumab combined with decitabine, with or without venetoclax. Pembrolizumab is an immunotherapy drug; decitabine helps produce normal blood cells by affecting DNA; venetoclax targets proteins essential for cancer cell survival. The goal is to see how well these drugs work together against AML/MDS.
What are the potential side effects?
Possible side effects include immune system reactions leading to inflammation in various organs, infusion-related reactions from the antibodies used in treatment, fatigue, digestive issues like nausea or constipation, low blood counts increasing infection risk, liver function changes and potential heart rhythm abnormalities.
