A Phase Ib/II Study of APG-2575 in Combination With Azacitidine in Patients With Acute Myeloid Leukemia (AML), Mixed Phenotype Acute Leukemia (MPAL), Chronic Myelomonocytic Leukemia (CMML) and Higher-Risk Myelodysplastic Syndrome (MDS
This is a Phase Ib/II, open-label, multi-center study evaluating the safety, tolerability, efficacy and PK of APG-2575 in combination with Azacitidine in the patients with AML/MPAL or MDS/CMML. The study consists of dose escalation (Part I) and dose expansion phase (Part II)
⁃ Patients with a diagnosis of histologically confirmed relapsed or refractory (R/R) acute myeloid leukemia (AML) or mixed phenotype acute leukemia (MPAL) or Chronic Myelomonocytic Leukemia (CMML) or relapsed/refractory Higher-Risk MDS by 2016 WHO classification for which no available standard therapies are indicated or anticipated to result in a durable response.
• MPAL will include biphenotypic leukemia, bilineal leukemia, undifferentiated leukemia, mixed lineage leukemia, leukemia of ambiguous lineage, T/myeloid leukemia, B/myeloid leukemia, or other diagnosis indicating the presence of multiple lineages within the cell population.
• Relapsed/refractory MDS will be defined as prior receipt of 4 cycles of HMA therapy with failure to attain a response, or progression of disease or relapse at any time after prior response to HMA therapy with Overall Revised International Prognostic Scoring System (IPSS-R) score \> 3 (intermediate, high or very high).
