Summary

This phase I/II trial studies the side effects and best dose of quizartinib when given with azacitidine and to see how well they work in treating patients with myelodysplastic syndrome or myelodysplastic/myeloproliferative neoplasm with FLT3 or CBL mutations. Chemotherapy drugs, such as azacitidine, 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. Quizartinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving azacitidine and quizartinib may help to control myelodysplastic syndrome or myelodysplastic/myeloproliferative neoplasm.

Detailed description

PRIMARY OBJECTIVES: I. To determine the safety, tolerability and maximum tolerable dose (MTD) of quizartinib in combination with azacytidine. II. To assess overall response (ORR) rate to quizartinib in combination with azacitidine. SECONDARY OBJECTIVES: I. To assess overall survival (OS), duration of response, leukemia-free survival (LFS), relapse-free survival (RFS) and safety profile. II. Correlative studies. OUTLINE: This is a phase I, dose-escalation study of quizartinib followed by a phase II study. Patients receive azacitidine subcutaneously (SC) or intravenously (IV) over about 30 minutes on days 1-5 and quizartinib orally (PO) once daily (QD) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at 30 days.
