Study Overview
Brief Summary
This phase I trial is studying the side effects and the best dose of entinostat when given together with sorafenib tosylate in treating patients with advanced or metastatic solid tumors or refractory or relapsed acute myeloid leukemia. Entinostat and sorafenib tosylate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
Detailed Description
PRIMARY OBJECTIVES:
I. To determine the maximum-tolerated dose of entinostat in combination with sorafenib tosylate in patients with advanced, inoperable, or metastatic solid tumors.
II. To determine the safety and tolerability of this regimen in these patients.
SECONDARY OBJECTIVES:
I. To determine the pharmacokinetic profile of this regimen in patients with refractory/relapsed acute myeloid leukemia (AML).

Arms & Interventions
Treatment (entinostat, sorafenib tosylate)
Patients receive oral entinostat once daily on days 1 and 15 and oral sorafenib tosylate twice daily on days 1-28 (days 15-28 only of course 1). Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Intervention: entinostat (Drug)
