The purpose of this two-stage Phase 2 study is to assess the clinical response (Complete Remission) of ACM (Alvocidib/Cytarabine/Mitoxantrone) compared to CM (Cytarabine/Mitoxantrone) treatment in refractory or relapsed AML patients with demonstrated MCL-1 dependence of ≥ 40% by mitochondrial profiling in bone marrow.
Phase 2, Randomized, Biomarker-driven Study in Patients With Relapsed or Refractory Acute Myeloid Leukemia (AML) With an Exploratory Arm in Patients With Newly Diagnosed High-Risk AML and Exploratory Arms With Varying Levels of MCL-1 Dependence
In Stage 1 of the study, all eligible AML patients with demonstrated MCL-1 dependence of ≥ 40% by mitochondrial profiling in bone marrow will receive treatment with ACM.
In Stage 2, all eligible AML patients with demonstrated MCL-1 dependence of ≥ 40% by mitochondrial profiling in bone marrow will be randomized 1:1 to receive either treatment with ACM or CM.
In the NDHR exploratory arm, all eligible patients with newly diagnosed high-risk (NDHR) AML with MCL-1 dependence of ≥40% by mitochondrial profiling in bone marrow will receive treatment with ACM.
In the MCL-1 dependency exploratory arms, all eligible AML patients with demonstrated MCL-1 dependence of ≥ 30 - <40% (Arm A), 15% - <30% (Arm B), or 0 - <15% (Arm C) by mitochondrial profiling in bone marrow who are either in first relapse (within 24 months of CR) or have primary refractory AML (ie, no CR or CRi after 2 cycles of intensive anthracycline/cytarabine ± etoposide or cladribine induction) will receive treatment with ACM.

- Have a left ventricular ejection fraction (LVEF) >45% by echocardiogram (ECHO) or multigated acquisition (MUGA) scan
- . Be nonfertile or agree to use an adequate method of contraception. Sexually active patients and their partners must use an effective method of contraception associated with a low failure rate during and for 6 months after completion of study therapy.
- . Be able to comply with the requirements of the entire study.
