Summary
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.
Objectives
The Phase 1 and Phase 2 Monotherapy arms have completed enrolment. The Phase 3
Monotherapy and Phase 1 Combination Therapy arms are open for enrolment.
