Brief Summary:
This study evaluates KRT-232, a novel oral small molecule inhibitor of MDM2, combined with low-dose cytarabine (LDAC) or Decitabine for the treatment of adults with Acute Myeloid Leukemia (AML) and AML secondary to myeloproliferative neoplasms (MPN). Participants must be relapsed/refractory (having failed prior therapy) and will be assigned to receive KRT+232 with LDAC or KRT-232 with Decitabine.
