Brief Title: A Phase 1 Trial of TST of PD 0332991 Followed by Cytarabine and Mitoxantrone for Adults With Relapsed and Refractory Acute Leukemias and High-Risk Myelodysplasia
Official Title: A Phase I and Pharmacodynamic Trial of Timed Sequential Administration of the Cyclin Dependent Kinase 4/6 Inhibitor PD 0332991 Followed by Cytarabine Plus Mitoxantrone for Adults With Relapsed and Refractory Acute Leukemias and High-Risk Myelodysplasias
Study ID: NCT01701375
Brief Summary: 1.1 Primary Objectives * To determine the feasibility, tolerability, and toxicities of administering the selective CDK 4/6 inhibitor PD 0332991 prior to the combination of ara-C and Mitoxantrone for adults with relapsed and refractory acute leukemias and high risk myelodysplasias (MDS), including primary refractory disease * To determine the direct cytotoxic effects of single agent PD 0332991 on malignant blasts * To determine the maximal tolerated dose (MTD) of PD 0332991 in timed sequential combination with ara-C and Mitoxantrone * To determine if the timed sequential combination of PD 0332991 with ara-C and mitoxantrone can induce clinical responses in adults with relapsed or refractory acute leukemias and high-risk MDS 1.2 Secondary Objectives: * To determine the ability of PD 0332991 to directly induce apoptosis in malignant cell populations in vivo * To obtain pharmacodynamic (PD) data regarding the ability of PD 0332991 to arrest malignant cells in the G 1 phase of cell cycle, followed by synchronized release of those cells into S phase upon discontinuation of PD 0332991 and resultant enhanced ara-C cytotoxicity
