Secondary Outcome Measures:
  • Toxicity of Combination of Ruxolitinib with Pracinostat [ Time Frame: 3 months ]
    Toxicity defined as Grade 3-4 clinically relevant non-hematologic toxicity or a serious adverse event that is at least possibly related to the study drug (Common Terminology Criteria for Adverse Events CTCAE version 4.0).

Arms Assigned Interventions
Experimental: Ruxolitinib + Pracinostat

Ruxolitinib starting dose 15 mg orally twice/day in 28-day cycle (dose assigned based on platelet count, if low platelet count gradual up-titration from a starting dose of 5 mg) - given alone for first 3 months, then Pracinostat added at starting dose 60 mg orally once/day for 3 alternating days every 3 weeks starting Day 1 of Cycle 4.

Dose of Ruxolitinib may be increased or decreased prior to initiation of Pracinostat. Quality of Life Questionnaire.

Drug: Ruxolitinib
Ruxolitinib taken by mouth 2 times each day in a 28-day cycle. Patients receive Ruxolitinib alone for first 3 months, and then Pracinostat added. Starting dose of Ruxolitinib based on patients' platelet count. Dose of Ruxolitinib may be increased or decreased at discretion of treating physician prior to initiation of Pracinostat.
Other Names:
  • Jakafi
  • INCB018424
  • INC424
Drug: Pracinostat
Starting dose of Pracinostat 60 mg by mouth 1 time each day for 3 alternating days every 3 weeks starting on Day 1 of Cycle 4.
Behavioral: Questionnaire
Questionnaire regarding quality of life completed at baseline, within 3 days before Day 1 of Cycles 1 - 6, and then every 3 cycles after that.

Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  1. Diagnosis of MF (either primary or post essential thrombocythemia/polycythemia vera) requiring therapy, including those previously treated and relapsed or refractory, or if newly diagnosed, with intermediate-1 or -2 or high risk according to International Prognostic Scoring System (IPSS).
  2. Palpable splenomegaly of more than or equal to 5 cm below left costal margin on physical exam
  3. Understanding and voluntary signing an IRB-approved informed consent form.
  4. Age equal to or more than 18 years at the time of signing the informed consent.
  5. Disease-free of other malignancies.
  6. ECOG performance status 0 to 2.
  7. Negative pregnancy test in females of childbearing potential (FCBP). Male patients with female partners of child-bearing potential and female patients of childbearing potential are required to use two forms of acceptable contraception, including one barrier method, during their participation in the study and for 30 days following last dose. Acceptable forms of contraception include 1 highly effective method such as an intrauterine device (IUD), hormonal (birth control pills, injections, or implants), tubal ligation, or partner's vasectomy and at least 1 additional approved barrier method such as a latex condom, diaphragm, or cervical cap. Female patients of childbearing potential must not be breast-feeding or planning to breast feed and must have a negative pregnancy test ≤7 days before first study treatment.
  8. QTcF interval equal to or less than 470 msec
  9. Normal serum potassium magnesium levels
  10. Adequate organ function as demonstrated by the following: Direct bilirubin equal to or less than 2.0 mg/dL, Serum creatinine equal to or less than 2.0 mg/dL., SGPT equal to or less than 3 x upper limit of normal (unless considered to be related to MF or patient has known history of Gilberts)
  11. Platelets >/= 50000/uL
  12. ANC >/= 1000/uL

Exclusion Criteria:

  1. Prior therapy with a JAK inhibitor (other than ruxolitinib for less than 3 months duration and currently on it) or HDACi. Patients that are currently on ruxolitinib for less than 3 months of therapy are eligible.
  2. Use of any other standard or experimental therapy within 14 days of starting study therapy.
  3. Lack of recovery from all toxicity from previous therapy to grade 1 or baseline.
  4. Suspected pregnancy, pregnant or lactating females.
  5. Any condition, including the presence of laboratory abnormalities, which in the opinion of the treating physician places the subject at unacceptable risk if he/she were to participate in the study or confounds the ability to interpret data from the study.
  6. Known positive for HIV or infectious hepatitis, type A, B or C.
  7. Patients with gastrointestinal (GI) tract disease, causing the inability to take oral medication, malabsorption syndrome, a requirement for intravenous (IV) alimentation, prior surgical procedures affecting absorption, uncontrolled inflammatory GI disease (e.g., Crohn's disease, ulcerative colitis)
  8. Cardiopulmonary function criteria: • Current unstable arrhythmia requiring treatment • History of symptomatic congestive heart failure • History of myocardial infarction within 6 months of enrollment • Current unstable angina • Family history of long QT syndrome
