ClinConnect Summary

This clinical trial is investigating a new treatment called MP0533 for patients with relapsed or refractory acute myeloid leukemia (AML) or myelodysplastic syndrome (MDS). The main goal is to see how safe the drug is, how well it is tolerated, and whether it shows any early signs of being effective in treating these conditions. The study is currently looking for participants aged 18 and older who have had their AML or MDS return after previous treatments, and who meet certain health criteria.

If you or a loved one is considering participation, you will need to provide written consent and have a life expectancy of at least 12 weeks. Participants should not have had recent major surgeries or certain other health conditions that could complicate the study. Throughout the trial, participants will be closely monitored for any side effects and how well the treatment is working. This study is an important step in finding new therapies for those facing these challenging blood cancers.
