Group Intervention Description Module 1: Dose Escalation AZD9829 Ascending dose level cohorts of AZD9829 in AML and MDS participants. Module 1: Dose Optimization AZD9829 Characterizing the safety, tolerability, PK/PD, and preliminary antitumor activity of AZD9829 in CD123+ R/R AML participants, based on the data collected during dose escalation, dose optimization and backfill.
- Primary Outcome Measures
Name Time Method Frequency of dose limiting toxicities (DLTs). Module 1 - 28 days. DLTs are dose-limiting toxicities as defined in the study protocol.
