Diagnosis of primary MF (PMF) or secondary MF (PET-MF and PPV-MF) as per WHO 2008 criteria.
Lead-in cohort: resistant or intolerant to 1 or more Janus kinase inhibitors (licensed or experimental).
Randomized cohort: resistant or intolerant to prior ruxolitinib therapy. Documentation by the Investigator that the patient has exhausted available treatment options (eg, resistant or intolerant to hydroxyurea, etc).
Spleen 5 cm below the inferior left costal margin as measured by manual palpation.
Active symptomatic MF as defined by the screening MPN-SAD patient-reported instrument requiring a severity score of at least 5 on one symptom, or a severity score of ≥ 3 on at least two of the symptoms (on a 0 to 10 scale).
Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, 2, or 3.
Adequate organ function, demonstrated by the following laboratory values:
1. Absolute Neutrophil Count 75 x 10(9)/L;
2. Platelet count \>50 x 10(9)/L with no evidence of bleeding and not requiring platelet transfusions;
3. Serum creatinine \<1.5 x upper limit of normal (ULN) or estimated creatinine clearance 60 mL/min (as calculated using the standard method of the institution);
4. Serum amylase or lipase \<1.5 x ULN;
5. Aspartate aminotransferase and alanine aminotransferase values 3.0 x ULN (or 5x ULN in the case of patients with MF accompanied by hepatic extramedullary hematopoiesis, as manifested by any degree of hepatomegaly).
6. Total bilirubin values \<1.5 x ULN unless the bilirubin is principally unconjugated (in the context of hemolysis) or there is documented Gilbert's disease.
7. Serum electrolyte values \< Grade 2 (sodium, potassium, calcium, phosphorous and magnesium), per CTCAE v.4.03.
Recovery to Grade 1 from all clinically significant adverse events related to prior MF therapy, including transplant-related toxicities.
More than 2 months out from allogenic hematopoietic stem cell transplant prior to randomization.
Must be able to undergo MRI of abdomen (spleen and liver). Patients who are contra indicated for MRI may be enrolled and evaluated by CT scan at the discretion of the Sponsor.
18 years of age.
Male subjects able to father children and female patients of childbearing potential and at risk for pregnancy must agree to use two highly effective methods of contraception throughout the study and for 90 days after the last dose of assigned treatment.
You may not be if
Prior treatment with a licensed or experimental smoothened inhibitor.
Randomized cohort only: Prior treatment with a Janus kinase inhibitor other than ruxolitinib.
Other anti-cancer therapy up to 14 days prior to enrollment, with the exception of hydroxyurea, which can be given up to 4 days prior to enrollment.
Splenic irradiation 3 months prior to enrollment.
History of congenital long QT syndrome, or a baseline \>470 msec QTcF abnormality (average of the triplicate reading).
Evidence of significant cardiac disease, for example: symptomatic cardiac heart failure (CHF, NYHA class 3), complete bundle branch block, significant atrial or ventricular tachyarrhythmias and any unstable cardiac arrhythmias requiring medication.
History of myocardial infarction or unstable angina within 6 months prior to enrollment.
Uncontrolled inflammatory bowel disease, peptic ulcer disease or history of significant gastro intestinal bleeding within 6 months of enrollment.
Any condition requiring chronic use of moderate/high dose steroids (equivalent to 10 mg QD prednisone).
Hematopoietic growth factor receptor agonists (eg, erythropoietin (Epo), granulocyte colony stimulating factor, romiplostim, eltrombopag within 28 days of enrollment.
Currently active malignancy (other than MF). Prior malignancies are allowed so long as there is no evidence of disease recurrence within the last 2 years (with the exception of fully excised, non-complicated basal cell carcinoma which can have been active within the prior 2 years, and certain localized, non-invasive fully excised skin, cervical, breast, prostate or bladder tumors).
Active, uncontrolled bacterial, fungal or viral infection, including hepatitis B, hepatitis C, known human immunodeficiency virus or acquired immunodeficiency syndrome related illness.
Active graft versus host disease (GVHD) with other than grade 1 skin involvement or GVHD requiring immunosuppressive treatment.
Current (including their administration within 3 days prior to study entry) use or anticipated need for food or drugs that are strong CYP3A4 inhibitors.
Current use or anticipated requirement for drugs that are known strong CYP3A4/5 inducers.
