Inclusion Criteria

During Prescreening:
1.Be between the ages of =18 and =65 years
2.Have an established, pathologically confirmed diagnoses of AML by World Health Organization (WHO) criteria excluding acute promyelocytic leukemia (APL-M3) with a bone marrow of >5% blasts based on histology or flow cytometry
3.Be in first relapse (within 24 months of CR) or have primary refractory AML (no CR or CRi after 2 cycles of intensive anthracycline/cytarabine ± etoposide or cladribine induction) or have NDHR AML as defined in this protocol (see Section 4.4.4)
4.Demonstrate MCL-1 dependence of =40% by mitochondrial profiling in bone marrow, 30 - <40% for MCL-1 Dependency Exploratory Arm A, 15% - <30% (MCL 1 Dependency Exploratory Arm B), or 0 - <15% (MCL-1 Dependency Exploratory Arm C).

During Screening:
5. Have an Eastern Cooperative Oncology Group (ECOG) performance status (PS) =2
6. Have a serum creatinine level =1.8 mg/dL
7. Have an alanine aminotransferase (ALT)/aspartate aminotransferase (AST) level =5 times upper limit of normal (ULN)
8. Have a total bilirubin level =2.0 mg/dL (unless secondary to Gilbert syndrome, hemolysis, or leukemia)
9. Have a left ventricular ejection fraction (LVEF) >45% by echocardiogram (ECHO) or multigated acquisition (MUGA) scan
10. 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.
11. Be able to comply with the requirements of the entire study.
12. Provide written informed consent prior to any study related procedure. (In the event that the patient is re-screened for study participation or a protocol amendment alters the care of an ongoing patient, a new informed consent form must be signed.)

Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes
F.1.2.1 Number of subjects for this age range 209
F.1.3 Elderly (>=65 years) no

Exclusion Criteria

1. Received more than 2 cycles of induction therapy for AML. Investigational agents as part of front-line therapy for AML may by acceptable following discussion with the Medical Monitor. Hydroxyurea is permitted (see #5 below).
2. Received any previous treatment with alvocidib or any other CDK inhibitor
3. Received a hematopoietic stem cell transplant within the previous 2 months
4. Have clinically significant graft versus host disease (GVHD), or GVHD requiring initiation or escalation of treatment within the last 21 days
5. Require concomitant chemotherapy, radiation therapy, or immunotherapy. Hydroxyurea is allowed up to the evening before starting (but not within 12 hours) of starting treatment on either arm.
6. Received >360 mg/m2 equivalents of daunorubicin
7. Have a peripheral blast count of >30,000/mm3 (may use hydroxyurea as in #5 above)
8. Received antileukemic therapy within the last 3 weeks (with the exception of hydroxyurea or if the patient has definite refractory disease). Refractory patients who received therapy within the last 3 weeks may be eligible with prior approval of the Medical Monitor.
9. Diagnosed with acute promyelocytic leukemia (APL, M3)
10. Have active central nervous system (CNS) leukemia
11. Have evidence of uncontrolled disseminated intravascular coagulation
12. Have an active, uncontrolled infection
13. Have other life-threatening illness
14. Have other active malignancies or diagnosed with other malignancies within the last 6 months, except nonmelanoma skin cancer or cervical intraepithelial neoplasia
15. Have mental deficits and/or psychiatric history that may compromise the ability to give written informed consent or to comply with the study protocol.
16. Are pregnant and/or nursing.
17. Have received any live vaccine within 14 days prior to first study drug administration.
