Summary

The goal of this Phase 1 clinical trial is to understand whether a new experimental treatment, called ORM-1153, will be a safe and possibly effective treatment option for participants with blood cancers such as Acute Myeloid Leukemia (AML) which have a particular protein (called Cluster of Differentiation 123 or CD123) on the cancer cell's surface. Phase 1 studies are designed to find a safe and effective dose. Participants will be receiving ORM-1153 at the defined study frequency as an infusion into the vein. They will need to visit the clinic frequently during the first few months of treatment.
