vosaroxin and azacitidine in treating patients with myelodysplastic syndromes

Conditions: Myelodysplastic Syndromes

Summary: this phase i trial studies the side effects and the best dose of vosaroxin when given together with azacitidine in treating patients with myelodysplastic syndromes. drugs used in chemotherapy, such as vosaroxin and azacitidine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing.
