Brief Summary
The purpose of the study is to determine if metformin in combination with cytarabine is safe and effective. Participants in this research study have acute myeloid leukemia (AML) that has come back after initial treatment or has not gone away with initial therapy.There is evidence that metformin directly kills leukemia cells. Laboratory data have also shown that combinations of metformin with cytarabine are more efficient than each agent alone in killing leukemia cells in the laboratory.

Outcome Measures
Primary Outcomes (2)
Evaluate Toxicity by Assessing the Adverse Events of Metformin and Cytarabine
To determine the maximum tolerated dose (MTD) by assessing the adverse events of metformin in combination with cytarabine in evaluating toxicity. Assessments will occur daily during cytarabine administration and at least twice weekly following treatment until blood count recovery.
Checked daily during administration of cytarabine and at least 2x weekly following therapy until desired blood counts acheived (maximum 15 days)
Study Treatment Dose Toxicity Will be Evaluated by Measurement of Adverse Events Experienced While on Treatment
Determination of Dose Limiting Toxicity (DLT) as evidenced by adverse events due to toxicity from study treatment. If no DLT is observed, then 3 patients will be enrolled in the next dose escalated cohort. If one DLT is seen in the first 3 patients, then an additional 3 patients will be enrolled at the same dose cohort. If 0-1 in 6 patients experience a DLT this dose will be considered tolerable and the next dose escalated cohort with enroll 3 patients. If 2 or more in 6 patients experience a DLT, the maximum tolerated dose (MTD) will have been exceeded and the next cohort will enroll 3 patients at a reduced dose.
Checked daily during administration of cytarabine and at least 2x weekly following therapy until desired blood counts acheived (maximum 15 days)
Secondary Outcomes (4)
Remission Rate
Every 3 months for 2 years, and then every 6 months for 5 years post-treatment
Overall Survival
Every 3 months for 2 years, and then every 6 months for 5 years post-treatment
Disease-free Survival
Every 3 months for 2 years, and then every 6 months for 5 years post-treatment
Length of Remission
From date of remission of disease to date of relapse (maximum of 5 year follow-up)
Other Outcomes (3)
Bone Marrow and Blood Samples Will be Taken Prior to Study Treatment to Determine Number of Leukemic Progenitor Cells
At baseline prior to study treatment
Immunoblotting
At baseline prior to study treatment
Identical Immunoblotting
At baseline prior to study treatment
Study Arms (1)
Treatment (enzyme inhibitor and chemotherapy)
EXPERIMENTALPatients receive metformin hydrochloride orally twice a day on days 1-15 and cytarabine IV over 3 hours twice on days 4-10.
Interventions
Given orally
Given IV
Eligibility Criteria
You may qualify if:
- Patients with relapsed/refractory disease must have morphologic proof (from bone marrow aspirate, smears or touch preps of bone marrow biopsy) of AML with \>= 10% blasts within two weeks (14 days) prior to initiation of therapy
- All immunophenotype and cytogenetic/molecular groups are eligible for participation except for acute promyelocytic leukemia (APL) (as proven by the presence of promyelocytic leukemia/retinoic acid receptor alpha \[PML-RARα\])
- Patients must demonstrate one of the following:
- Relapse after first complete remission
- Refractory to conventional induction chemotherapy (failure to respond to 1 or more cycles of daunorubicin and cytarabine) or to re-induction
- Patients with previously untreated AML are candidates if they are unable to receive anthracyclines, and have documented AML with \>= 20% blasts within one week prior to enrollment
- Patients with chronic myelogenous leukemia (CML) in myeloid blast crisis are eligible if their disease has failed to respond, and/or they are intolerant, to the available tyrosine kinase inhibitors (TKIs)
- Serum total and direct bilirubin =\< upper limit of normal (ULN)
- Serum creatinine \< 1.4 mg/dl in females and \< 1.5 mg/dl in males, and creatinine clearance \> 60 mL/min
- Serum glutamic oxaloacetic transaminase (SGOT) (aspartate aminotransferase \[AST\])/serum glutamic pyruvate transaminase (SGPT) (alanine aminotransferase \[ALT\]) =\< ULN
- Bicarbonate within the normal range of the hospital lab (24-32 mmol/L)
- Patients must exhibit an Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2
- Females of childbearing potential and sexually active males must agree to use an accepted and effective method of contraception while on study
- Childbearing potential is defined as 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; OR
- +5 more criteria
You may not qualify if:
- Patients who have received chemotherapy or radiotherapy within 4 weeks prior to enrollment are NOT eligible for participation
- The exception to this is patients who are refractory to conventional initial induction chemotherapy (=\< 2 courses) or to first radiation (1 course); patients must have morphologic proof (from bone marrow aspirate, smears, or touch preps of marrow biopsy) of AML with \> 10% blasts within 2 weeks prior to initiation of study therapy; the last dose of cytotoxic therapy (NOT including hydrea, which is allowed) must have been given \>= 14 days prior to initiation of study therapy
- Patients with a history of diabetes mellitus (DM) treated with metformin are NOT eligible for participation
- Patients who are pregnant or breast feeding are NOT eligible for participation due to the lack of knowledge regarding the effects of the drugs on the fetus and during breast feeding
- Patients with any intercurrent organ damage or medical problems that would prohibit therapy are NOT eligible for participation
- Patients with any active, uncontrolled infection are NOT eligible for participation
- Patients who are receiving therapy for another active malignancy are NOT eligible for participation
- The exception to this is squamous cell carcinoma or basal cell carcinoma of the skin
