Ruxolitinib in Combination With Nilotinib in Chronic Myeloid Leukemia (CML) Patients

"Participants will remain on the same dose of nilotinib they have been receiving prior to enrollment on the trial. This will range from 300 mg PO BID to 400 mg PO BID.~Dose modifications will not occur, as the purpose of this study is to determine the maximum tolerated dose of ruxolitinib, based on the number of dose."

Dose escalation will follow a 3+3 study design. Dose modifications will not occur, as the purpose of this study is to determine the maximum tolerated dose, based on the number of dose limiting toxicities seen at a specific dose.
