Phase 1/2RecruitingAptose Biosciences Inc.NCT03850574Data as of May 2026

Treatment: Tuspetinib · Venetoclax Oral Tablet · Azacitidine for Intravenous InfusionThe main purpose of this study is to identify a safe and potentially effective dose of tuspetinib to be used in future studies in study participants diagnosed with acute myeloid leukemia (AML), myelodysplastic syndromes with increased blasts grade 2 (MDS-IB2), or chronic myelomonocytic leukemia (CMML) that is relapsed or refractory after at least one line of prior therapy, or in study participants with newly diagnosed AML. Tuspetinib will be administered as a single agent or in combination with other drugs (venetoclax or venetoclax plus azacitidine), as specified for each part of the study.
