Eligibility
Inclusion criteria
Inclusion criteria: - Diagnosis of PMF, PPV-MF, or PET-MF. - DIPSS risk category of intermediate-1, intermediate-2, or high. - Palpable spleen of >= 5 cm below the left costal margin on physical examination at the screening visit. - Active symptoms of MF at the screening visit, as demonstrated by the presence of a TSS of >= 10 using the Screening Symptom Form. - Participants with an ECOG performance status score of 0, 1, or 2. - Screening bone marrow biopsy specimen and pathology report(s) available that was obtained within the prior 2 months or willingness to undergo a bone marrow biopsy at screening/baseline; willingness to undergo bone marrow biopsy at Week 24 and every 24 weeks there after. Screening/baseline biopsy specimen must show diagnosis of MF. - Life expectancy of at least 24 weeks. - Willingness to avoid pregnancy or fathering children.
Exclusion criteria
Exclusion criteria: - Prior use of any JAK inhibitor. - Prior therapy with any drug that inhibits PI3K (examples of drugs targeting this pathway include but are not limited to INCB040093, idelalisib, duvelisib, buparlisib, copanlisib, and umbralisib). - Use of experimental drug therapy for MF or any other standard drug (eg, danazol, hydroxyurea) used for MF within 3 months of starting study drug and/or lack of recovery from all toxicities from previous therapy to <= Grade 1. - Inability to swallow food or any condition of the upper gastrointestinal tract that precludes administration of oral medications. - Recent history of inadequate bone marrow reserve. - Inadequate liver and renal function at screening. - Active bacterial, fungal, parasitic, or viral infection that requires therapy. - Active HBV or HCV infection that requires treatment or at risk for HBV reactivation. - Known HIV infection. - Uncontrolled, severe, or unstable cardiac disease that in the investigator's opinion may jeopardize the safety of the participant or compliance with the Protocol. - Active invasive malignancy over the previous 2 years. - Splenic irradiation within 6 months before receiving the first dose of study drug. - Concurrent use of any prohibited medications. - Active alcohol or drug addiction that would interfere with the ability to comply with the study requirements. - Use of any potent CYP3A4 inhibitors or inducers within 14 days or 5 half lives(whichever is longer) before the first dose of study drug or anticipated during the study. - Inadequate recovery from toxicity and/or complications from a major surgery before starting therapy. - Currently breastfeeding or pregnant. - Any condition that would, in the investigator's judgment, interfere with full participation in the study, including administration of study drug and attending required study visits; pose a significant risk to the participant; or interfere with interpretation of study data. - History of Grade 3 or 4 irAEs from prior immunotherapy. - Receipt of any live vaccine within 30 days of the first dose of study drug
