This is a single center phase I dose-escalation trial of Fedratinib in Combination with Decitabine in Patients with Myeloproliferative Neoplasms. The primary objective is to determine the maximum tolerated dose of the combination therapy, using a 3+3 dose escalation algorithm. Fedratinib will be administered at 2 dose levels: 300 mg and 400 mg by mouth, once daily. Fedratinib will be administered concomitantly with decitabine 20 mg/m2 intravenously over 1 hour per day for 5 days in 28-day cycles.
The purpose of this research is to study the safety and tolerability and to establish the maximum tolerated dose (MTD) of the combination of two drugs, fedratinib and decitabine, for the treatment of advanced-phase MPNs.
