A Multi-phase Study of ASTX030 (Azacitidine and Cedazuridine) in Myeloid Neoplasm Alone or in Combination With Venetoclax in AML (AZTOUND Study)

Study ASTX030-01 is a multi-phase study comprising of Phases 1-3 Monotherapy arms, and Phase 1 and Phase 2 Combination Therapy arms. 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 treatment-naïve AML. Phase 2 Combination Therapy is an open-label, single arm, study evaluating the efficacy, safety, pharmacokinetics (PK), and drug interactions of ASTX030 in combination with venetoclax in participants with treatment-naïve AML. The duration of this multi-phase study is approximately 8 years.
