Study Phase: Phase 2
Recruitment Status: Recruiting
Start Date: June 01, 2016
End Date: June 01, 2019
Inclusion Criteria:
- Diagnosis of primary myelofibrosis, post-polycythemia vera myelofibrosis, or post-essential thrombocythemia myelofibrosis
- Palpable spleen of > 10 cm below the left subcostal margin on physical examination at the screening visit OR
- Palpable splenomegaly of 5 to 10 cm below left subcostal margin on physical exam AND active symptoms of MF at the screening visit as demonstrated by presence of 1 symptom score ≥ 5 or 2 symptom scores ≥ 3 using the Screening Symptom Form
- Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2
Exclusion Criteria:
- Use of experimental drug therapy for myelofibrosis, or any other standard drug (eg, danazol, hydroxyurea, etc) with the exception of ruxolitinib within 6 months of starting study (combination) therapy and/or lack of recovery from all toxicities from previous therapy (except ruxolitinib) to Grade 1 or better
- Inability to swallow food or any condition of the upper gastrointestinal tract that precludes administration of oral medications
- Unwillingness to be transfused with blood components
- Recent history of inadequate bone marrow reserve as demonstrated by the following:
- Platelet count < 50 × 10^9/L in the 4 weeks before screening or platelet transfusion(s) within 8 weeks before screening
- Absolute neutrophil count levels < 0.5 × 10^9/L in the 4 weeks before screening
- Subjects with peripheral blood blast count of > 10% at the screening or baseline hematology assessments
- Subjects who are not willing to receive red blood cell (RBC) transfusions to treat low hemoglobin levels
- Inadequate liver function at screening as demonstrated by the following:
- Direct bilirubin ≥ 2.0 × the upper limit of laboratory normal (ULN). (NOTE: direct bilirubin will only be determined if total bilirubin is ≥ 2.0 × ULN)
- alanine aminotransferase (ALT) or aspartate aminotransferase (AST) > 2.5 × ULN
- Inadequate renal function at screening as demonstrated by creatinine clearance < 50 mL/min or glomerular filtration rate < 50 mL/min/1.73 m^2
