Brief summary: This randomized phase II trial studies how well cytarabine with or without SCH 900776 works in treating adult patients with relapsed acute myeloid leukemia. Drugs used in chemotherapy, such as cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or stopping them from dividing. SCH 900776 may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. It is not yet known whether cytarabine is more effective with or without SCH 900776 in treating acute myeloid leukemia.

Detailed description: PRIMARY OBJECTIVES:

I. To compare the rates of complete remission (CR) plus CR with incomplete recovery (CRi) achieved with cytosine arabinoside (ara-C) (cytarabine) plus the checkpoint kinase 1 (CHK1) inhibitor MK-8776 (Chk1 inhibitor SCH 900776) vs. ara-C alone for adults (ages 18-75) with relapsed acute myelogenous leukemia (AML).

SECONDARY OBJECTIVES:

I. To evaluate and compare the toxicities of ara-C + MK-8776 vs. ara-C alone. II. To determine the disease free and overall survival of those achieving response to treatment.

III. To determine the impact of MK-8776 on AML blast cell deoxyribonucleic acid (DNA) repair protein expression profiles and correlate the expression profiles with CR/CRi in response to ara-C + MK-8776 vs. ara-C alone.

IV. To evaluate and compare the amount of DNA damage induced in AML blasts by ara-C + MK-8776 vs. ara-C.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM A: Patients receive cytarabine intravenously (IV) continuously over 72 hours on days 1-3 and 10-12 and Chk1 inhibitor SCH 900776 IV over 30 minutes on days 2, 3, 11, and 12.

ARM B: Patients receive cytarabine as in Arm A.

In both arms, courses may repeat every 28 days.

After completion of study treatment, patients are followed up periodically.

Eligibility criteria: Inclusion Criteria:

* Adults with the established, pathologically confirmed diagnosis of relapsed AML
* AML that has relapsed at least once or is primary induction failure
* Eastern Cooperative Oncology Group (ECOG) performance status 0-2

* Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for 30 days after study participation; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
* Patients who have undergone stem cell transplantation (SCT), autologous or allogeneic, are eligible provided that they are \>= 4 weeks from stem cell infusion, have no active graft-vs-host disease (GVHD), and meet other eligibility criteria
* Patients who fail primary induction therapy or relapse after achieving complete remission (CR) are eligible if they have undergone no more than 2 prior cytotoxic regimens (a regimen is described as a distinctive planned collection of agent\[s\] and/or modalities to be utilized together during a cycle or course of therapy; i.e., induction+consolidation with or without stem cell transplant \[SCT\]), \>= 2 weeks off cytotoxic chemotherapy, and \>= 2 weeks off radiation therapy; patients must be off biologic therapies including hematopoietic growth factors \>= 2 weeks; if using hydroxyurea (HU), steroids, imatinib or other tyrosine kinase inhibitors (TKIs), interferon, or other non-cytotoxics for blast count control, patient must be off for \>= 24 hours (hrs) before starting MK-8776
* Fluvoxamine and ciprofloxacin must be stopped 7 days prior to day 1 of therapy, and be excluded during administration of study therapy; if the subject is using any of the other drugs that are cytochrome P4501A2 (CYP1A2) or P-glycoprotein (PgP) inhibitors, substitution should be considered and administration of these drugs should be avoided on the days of administration of MK-8776; in addition, smoking should be avoided and cytochrome P450 3A4 (CYP3A4) substrates with a narrow therapeutic index should be avoided: alfentanil, astemizole, cisapride, cyclosporine, diergotamine, ergotamine, fentanyl, pimozide, quinidine, sirolimus, tacrolimus, terfenadine

Exclusion Criteria:

* Any previous treatment with MK-8776
* Considered refractory or treatment failure to most recent treatment regimen, unless primary refractory
* Concomitant chemotherapy, radiation therapy, or immunotherapy
* Hyperleukocytosis with \>= 50,000 blasts/uL (if using HU, steroids, tyrosine kinase/src inhibitors (including fms-related tyrosine kinase 3 \[FLT3\] inhibitors), arsenic, interferon or leukapheresis for blast count control, patient must be off those agents for 24 hours prior to beginning ara-C +/- MK-8776)
* Acute progranulocytic leukemia (APL, M3)
* Active disseminated intravascular coagulation (DIC)
* Active central nervous system (CNS) leukemia
* Active, uncontrolled infection; patients with infection under active treatment and controlled with antibiotics are eligible
* Presence of other life-threatening illness
* Patients with mental deficits and/or psychiatric history that preclude them from giving informed consent or from following protocol
