EXPANSION COHORT: Patients must have a diagnosis of newly diagnosed AML with any of the following:

Note: Patients with secondary AML are eligible for enrollment into the trial (in both cohorts); secondary AML is defined as AML that has developed in a person with a history of antecedent blood count abnormalities, or myelodysplastic syndromes (MDS), or a myeloproliferative disorder (excluding chronic myeloid leukemia); or a history of prior chemotherapy or radiation therapy for a disease other than AML
Patients who are not candidates for, or decline, intensive therapy
Patients must exhibit an ECOG performance status 0-3
International normalized ratio (INR) ? 2 (If coagulopathy is related to disease, this criterion does not apply) within14 days prior to registration
Prothrombin time (PT) and partial thromboplastin time (PTT) ? 1.5 x of institutional upper limit of normal (ULN) (Note: If coagulopathy is related to disease, this criteria do not apply) within14 days prior to registration
Total bilirubin ? 1.5 x of institutional ULN within14 days prior to registration
Aspartate aminotransferase (AST) (serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamic pyruvic transaminase [SPGT]) 1.5 X institutional upper limit of normal (ULN) within14 days prior to registration
Creatinine 2 x ULN OR creatinine clearance > 30 mL/min based on the Cockroft-Gault glomerular filtration rate (GFR) estimation

Females of child-bearing potential (FOCBP) and males must agree to use medically acceptable method of contraception (e.g. a method which results in a low failure rate of less than 1% per year when used consistently and correctly such as implants, injectables, combined oral contraceptives, some intrauterine devices or vasectomized partner for participating females, latex condoms for participating males, sexual abstinence) prior to study entry, for the duration of study participation, and for 3 months following completion of therapy; should a female patient become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately; if the female partner of a male participant becomes pregnant he should inform the treating physician and the female partner should contact her treating physician immediately

NOTE: A FOCBP is any woman (regardless of sexual orientation, having undergone a tubal ligation, or remaining celibate by choice) who meets the following criteria:

Has not undergone a hysterectomy or bilateral oophorectomy
Has had menses at any time in the preceding 12 consecutive months (and therefore has not been naturally postmenopausal for > 12 months)
FOCBP must have a negative pregnancy test (beta-human chorionic gonadotropin [HCG] test in urine or serum) within 7 days prior to registration on study (Note: The test will have to be repeated if cycle 1 day1 is more than 3 days from registration)
Patients must have the ability to understand and the willingness to sign a written informed consent prior to registration on study
Patients must agree/be able to comply with all protocol specific requirements

Exclusion Criteria:

Patients who have received chemo-, hormone-, radio or immunotherapy or therapy with monoclonal antibodies or small tyrosine kinase inhibitors within the past 14 days prior to start of treatment or those who have not recovered from adverse events attributed to the agent to grade 1 or baseline

Exceptions for prior treatments are:

Hydroxyurea for increased blast count (no washout period required; it can be continued throughout the first cycle of therapy)

Leukapheresis for leukocytosis (no wash out period required; it can be continued during the study)

Note: If patient is registered prior to completion of washout, start date of treatment will need to be confirmed prior to registration; please see assigned quality assurance monitor (QAM) with questions

Patients who have received any other investigational product within14 days of treatment are not eligible for this study; a wash out period ? 14 days or 5 half- lives (whichever is greater) is required from investigational treatment, prior to start of study treatment; please Note:

If patient is registered prior to completion of washout, start date of treatment will need to be confirmed prior to registration; please see assigned QAM with questions
The ?5 half-lives? time period will be determined by investigational pharmacy
If half life is not known and cannot be predicted, then wash out of ? 14 days is required
Patients who have had major injuries and/or surgery within the past 4 weeks (< 28 days) prior to registration with incomplete wound healing and/or planned surgery while the patient is on study treatment
Patients who have proteinuria CTCAE version (v)4.03 grade 2 or greater within < 30 days of registration

Patients who have significant cardiovascular diseases are not eligible; these are:

Uncontrolled hypertension

Active uncontrolled infection
Serious illness or concomitant non-oncological disease such as neurologic, psychiatric, infectious disease or active ulcers (gastrointestinal tract, skin) or laboratory abnormality that may increase the risk associated with study participation or study drug administration and in the judgment of the investigator would make the patient inappropriate for entry into the study
