Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Study ASTX030-01 is a multi-phase study comprising of Phases 1-3 Monotherapy arms and a Phase 1 Combination Therapy arm Phase 1 Monotherapy consists of an open-label Dose Escalation Stage (Stage A) using multiple cohorts at escalating dose levels of oral cedazuridine and azacitidine (only one study drug will be escalated at a time) followed by a Dose Expansion Stage (Stage B). Phase 2 Monotherapy is a randomized, open-label, crossover study to compare oral ASTX030 to subcutaneous (SC) azacitidine. Phase 3 Monotherapy is a randomized open-label crossover study comparing the final fixed dose of oral ASTX030 to SC azacitidine. Phase 1 Combination Therapy is an open-label, multicenter, randomized, exploratory study comparing ASTX030 and SC azacitidine in combination with venetoclax in participants with AML.

The duration of this multi-phase study is approximately 7 years.
