Clinical Trial Summary

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.

Description:

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.

Eligibility

Inclusion Criteria:

• Subjects must have MPN-AP as defined by 10%-19% blasts in the peripheral blood or bone marrow and evidence of dysplastic marrow features with a concomitant diagnosis of essential thrombocythemia (ET), polycythemia vera (PV) or primary myelofibrosis (PMF) or a diagnosis of MPN-BP as defined by 20% blasts in the blood or bone marrow following a previous diagnosis of ET, PV or PMF.
• Subjects must have adequate organ function documented within 14 days of study entry as

follows:

1. Estimated creatinine clearance (by Cockcroft-Gault Equation) of = 50 mL/min

2. Serum total bilirubin = 1.5 × ULN (unless attributable to Gilbert's disease or hemolysis, in which case the direct bilirubin level must be = 1.5 × upper limit of normal (ULN)).

3. Alkaline phosphatase, serum aspartate aminotransferase (AST) and alanine transaminase (ALT) = 2.5 × ULN.

• = 18 years of age.
• Eastern Cooperative Oncology Group (ECOG) Performance status of 0-2. Patients with ECOG performance status of 3 will be eligible if the lower performance status is deemed by the investigator to be due entirely to MPN-AP/BP and not due to another comorbidity.

Exclusion Criteria:

• Receipt of chemotherapy or investigational therapy, with the exception of hydroxyurea, within 4 weeks of study entry. Previous treatment at any time with decitabine, fedratinib or ruxolitinib as single agents will not exclude eligibility. Previous stem cell transplant will not exclude eligibility as long as other inclusion/exclusion criteria have been met and subjects do not have Grade = II graft-versus-host disease (GVHD) requiring systemic immunosuppressive therapy.
• Subjects with an Human leukocyte antigen (HLA)-compatible donor or stem cell source who are immediate candidates for allogeneic hematopoietic cell transplantation (HCT).
• Subjects who are receiving any concurrent treatment for acute myeloid leukemia (AML), including other investigational agents.
• Diagnosis of acute myelofibrosis.
• Uncontrolled intercurrent illness including, but not limited to hepatitis, human immunodeficiency virus (HIV)-positive subjects receiving combination antiretroviral therapy, ongoing or active infection, symptomatic congestive heart failure (New York Heart Association Class 3 or 4), unstable angina pectoris, ventricular arrhythmia, Child-Pugh Class C cirrhosis, or psychiatric illness/social situations that would limit compliance with study requirements.
• Subjects with a prior history of Wernicke's encephalopathy (WE) will be excluded. If a subject has signs or symptoms of encephalopathy, including Wernicke's encephalopathy (e.g. severe ataxia, ocular paralysis or cerebellar signs), thiamine deficiency must be excluded and a brain MRI should be obtained prior to study initiation to evaluate for WE.
• Other medications, severe acute/chronic medical or psychiatric conditions, or laboratory abnormalities that may increase the risk associated with study participation or study drug administration, or may interfere with the interpretation of study results, that in the judgment of the Investigator would make the subject inappropriate for entry into this study.
• Pregnant women are excluded because of the potential for teratogenic or abortifacient effects.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Maximum Tolerated Dose (MTD) of Decitabine and Fedratinib	The MTD will be determined using a 3+3 algorithm. If < 33% of the subjects enrolled at a dose level experience a dose-limiting toxicity (DLT), escalation to the next designated dose cohort will continue. If = 33% of the subjects enrolled at a dose level experience a DLT, the previous dosing cohort will be considered the MTD. DLT is defined as: (1) Grade 3, 4, or 5 non-hematologic toxicity considered at least possibly related to the study drug, except for infection, bleeding, fever, fatigue, dyspnea, and (2) Grade 3, 4, or 5 anemia, neutropenia or thrombocytopenia with a hypocellular bone marrow and < 5% marrow blasts lasting for 42 days or more.	Up to 8 weeks for each dosing cohort
Secondary	Complete Remission (CR) Rate	Complete remission defined as participants that are free of all symptoms related to leukemia and have an absolute neutrophil count = 1 x 10^9/L, no need for red blood cell transfusion, platelet count = 100 x 10^9/L, and normal marrow differential (= 5 % blasts) in a normo- or hypercellular marrow.	Up to 3 years
Secondary	Composite Complete Remission (CRc) Rate	CRc defined as (CR + Complete remission with incomplete count recovery (CRi)). CRi defined as CR but incomplete count recovery (absolute neutrophil count < 1000/microL or platelet count < 100,000/micro/L).	Up to 3 years
Secondary	Partial Remission (PR) Rate	PR defined as CR with 6 - 25 % abnormal cells in the marrow or 50 % decrease in bone marrow blasts.	Up to 3 years
Secondary	Progression Free Survival (PFS)	PFS is defined as the duration of time from entry on study to time of recurrence, flow cytometric relapse, cytogenetic relapse, molecular relapse, or death, whichever occurs first.	Up to 3 years
Secondary	Overall Survival (OS)	OS is defined as the duration of time from entry on study to time of death from any cause.	Up to 3 years
