Sertraline and Cytosine Arabinoside in Adults With Relapsed and Refractory AML

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.
