A Phase I/II Study of Ruxolitinib in Combination With Nilotinib in Patients With Chronic Phase CML Who Have Achieved a Complete Hematologic Remission, Complete Cytogenetic Remission, and Major Molecular Remission, But Not a Complete Molecular Remission on a Tyrosine Kinase Inhibitor Alone.

研究概览
简要总结
This study combines two drugs (ruxolitinib and the tyrosine kinase inhibitor, nilotinib) in an attempt to eliminate the CML (Chronic Myeloid Leukemia) stem cell population and thus allow for the deepest and most durable response possible in patients with CML in chronic phase who have achieved a complete hematologic remission (CHR), complete cytogenetic remission (CCyR), and major molecular remission (MMR), but not a complete molecular remission (CMR). The study will look at safety and tolerability of ruxolitinib when combined with nilotinib in a phase I study and will help establish the MTD (Maximum Tolerated Dose) of ruxolitinib when combined with nilotinib. Once the optimal dose of ruxolitinib is established in the phase I setting, a phase II evaluation will seek to establish the efficacy of this combination.

研究组 & 干预措施
Nilotinib + Ruxolitinib
The first part of the trial will be Phase I and will enroll 25 participants. Participants will receive nilotinib BID and either 10, 15 or 20 mg of ruxolitinib BID. Maximum tolerated dose (MTD) of ruxolitinib will be determined.
The second part of the trial will be a Phase II and will enroll 25 subjects. Participants will receive nilotinib and the MTD of ruxolitinib.
