This is a Phase I study with the goals of determining the feasibility, safety, and toxicity of administering sertraline in combination with timed-sequential cytosine arabinoside (ara-C) in adults with relapsed and refractory acute myeloid leukemia (AML). Primary objective: * To define the maximum tolerated dose (MTD) and Recommended Phase II Dose (RP2D) of sertraline administered in combination with timed-sequential cytosine arabinoside in adult patients with relapsed and refractory acute myeloid leukemia. * To evaluate the safety and tolerability of sertraline given in combination with timed-sequential cytosine arabinoside in adult patients with relapsed and refractory acute myeloid leukemia.
Relapsed and refractory acute myeloid leukemias are characterized by net drug resistance. At the root of this drug resistance is an enhanced survival that relates to intrinsic cell cycle dysregulation and aberrations in the overall process of the repair of DNA damage. These malignancies represent a continuing therapeutic challenge, since currently no "standard treatments" for these diseases exist. Approximately 30% of adults with newly diagnosed AML are primary refractory to chemotherapy and at least 50% of those who achieve remission will relapse. For patients with relapsed or refractory AML, the expected CR/CRi rates with traditional multi-agent chemotherapies range from \< 10% for primary refractory AML to 25-30% for relapsed AML and cure rates \< 20%, even with allogeneic stem cell transplantation. Thus, novel treatment approaches are needed.

Sertraline is a selective serotonin reuptake inhibitor (SSRI) that is FDA approved to treat major depressive disorder, obsessive-compulsive disorder, panic disorder, post-traumatic stress disorder, premenstrual dysphoric disorder, and social anxiety disorder. Sertraline will be administered orally twice a day starting on day -3. Sertraline will be administered at one of 4 pre-defined dose levels in the following dose-escalation: 50 mg daily, 50 mg twice a day, 50 mg every morning (QAM) and 100 mg every evening (QPM), 100 mg twice a day. 100 mg QAM and 150 mg QPM.
Cytarabine is a cytotoxic chemotherapy approved for use in acute myeloid leukemia, acute lymphoblastic leukemia, and chronic myelogenous leukemia. It is also approved to prevent and treat meningeal leukemia. Cytarabine kills cells in S-phase through inhibition of DNA polymerase, as well as by halting DNA synthesis after its incorporation into DNA. Cytosine arabinoside (Ara-C) will be administered as a 72 hour intravenous continuous infusion (IVCI) beginning Day 1 of therapy and again beginning Day 10 of therapy. The total dose of ara-C for each 72 hour period is 2 gm/m2 (0.667 gm/m2/24 hours).
Allogeneic stem cell transplantation involves transferring the stem cells from a healthy person (the donor) to a patient after high-intensity chemotherapy or radiation.

Maximum Tolerated Dose (MTD) of sertraline administered in combination with timed-sequential cytosine arabinoside
Standard 3+3 dose-escalation design will be used to determine the MTD. The MTD will be determined as the highest dose level where 1/6 patients experience dose-limiting toxicity (DLT). Three patients will be treated at a given dose level combination and observed for at least 4 weeks to assess toxicity. Doses will not be escalated in any individual patient.
