Study of Obatoclax in Previously Untreated Acute Myeloid Leukemia (AML)

Study Overview
=================
Brief Summary
-----------------
This protocol will evaluate the efficacy of obatoclax in older patients with previously untreated AML.

Detailed Description
-----------------
The Pilot Safety portion of the study will evaluate the safety of obatoclax administered by a 3 hour infusion for 3 days in a row. The Pilot Schedule portion of the study will randomize 16 patients in to one of two cohorts: 1) patients receiving obatoclax administered by a 3 hour infusion for 3 days in a row or 2) patients receiving obatoclax administered by a 24 hour infusion for 3 days in a row. The schedule with the best overall efficacy and safety in the Pilot Schedule portion of the study will then be utilized in the Phase II portion of the study.
