Study Overview
Brief Summary
This phase I trial studies the side effects and best dose of azacitidine when given together with mitoxantrone, etoposide phosphate, and cytarabine in treating patients with acute myeloid leukemia that has returned after a period of improvement or does not respond to treatment. Azacitidine may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as mitoxantrone, etoposide phosphate, and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Azacitidine may help mitoxantrone, etoposide phosphate, and cytarabine work better by making cancer cells more sensitive to the drugs.
Detailed Description
PRIMARY OBJECTIVES:
I. To determine the maximum-tolerated dose of azacitidine (5-azaC) when combined with mitoxantrone hydrochloride (mitoxantrone), etoposide phosphate (etoposide), and cytarabine (MEC) as salvage chemotherapy in patients with relapsed or refractory acute myeloid leukemia (AML).
SECONDARY OBJECTIVES:
I. To define the qualitative and quantitative toxicities of 5-azaC with MEC in combination with regard to organ specificity, time course, predictability, and reversibility.
II. To document the rate of complete remission (CR) and CR with incomplete blood count recovery (CRi) for this combination of agents as well as overall survival, relapse-free survival, and event-free survival.
