You may be eligible if
Must complete the Myelofibrosis Symptom Assessment Form (MFSAF) v4.0 on at least 4 out of the 7 days immediately prior to the date of randomization and must agree to collect MFSAF data daily by ePRO device during the study collection window.
\-- Has at least 2 symptoms each with an average score \>= 3 or an average total score of \>= 12, as measured by the MFSAF v4.0.
Documented diagnosis of primary myelofibrosis (MF) as defined by the World Health Organization (WHO) classification, post polycythemia vera (PPV)-MF, or post essential thrombocytopenia (PET)-MF, characterized by bone marrow fibrosis grades 2 or 3.
Classified as intermediate-2 or high-risk MF, as defined by the Dynamic International Prognostic Scoring System Plus (DIPSS+).
Must currently be on treatment or have received prior treatment with a single Janus Kinase 2 (JAK2) inhibitor, ruxolitinib, and meet one of the following criteria (in addition to the minimum splenomegaly and symptom burden also required for eligibility):
* Treatment with ruxolitinib for \>= 24 weeks that was stopped due to lack of spleen response (refractory), or loss of spleen response or symptom control after a previous response (relapsed), or was continued despite relapsed/refractory status.
* Treatment with ruxolitinib for \< 24 weeks with documented disease progression while on therapy as defined by any of the following:
* Appearance of new splenomegaly that is palpable to at least 5 cm below the left costal margin (LCM) in participants with no evidence of splenomegaly prior to the initiation of ruxolitinib.
* A \>= 100% increase in the palpable distance below the LCM in participants with measurable spleen distance 5 to 10 centimeters (cm) prior to the initiation of ruxolitinib.
* A \>= 50% increase in the palpable distance below the LCM in participants with measurable spleen distance \> 10 cm prior to the initiation of ruxolitinib.
* A spleen volume increase of \>= 25% (as assessed by Magnetic Resonance Imaging \[MRI\] or Computed Tomography \[CT\] scan) in participants with a spleen volume assessment prior to the initiation of ruxolitinib.
* Prior treatment with ruxolitinib of at least 10 mg twice daily (BID) for \>= 28 days with intolerance defined as new RBC transfusion requirement (at least 2 units/month for 2 months) while receiving a total daily ruxolitinib dose of \>= 30 mg but unable to reduce dose further due to lack of efficacy.
Note: Participant must not require a ruxolitinib dose less than 10 mg BID (20 mg daily) due to prior history of ruxolitinibrelated ≥ Grade 3 toxicity.
Eastern Cooperative Oncology Group (ECOG) performance status of 0, 1, or 2.
Splenomegaly defined as palpable spleen measurement \>= 5 cm below left costal margin or spleen volume \>= 450 cm3 as assessed centrally by MRI or CT scan.
Baseline platelet count \>= 100 × 10\^9/L.
You may not be if
Received prior treatment with a B-cell lymphoma 2 homology 3 (BH3)-mimetic compound, bromodomain and extra-terminal (BET) inhibitor, phosphoinositide 3- kinase and telomerase inhibitors (e.g., parsaclisib), prior use of \> 1 JAK2 inhibitor or stem cell transplant.
Eligible for stem cell transplantation at the time of study entry.
Receiving medication that interferes with coagulation or platelet function within 3 days prior to the first dose of study drug or during the study treatment period except for low dose aspirin (up to 100 mg daily) and low molecular weight heparin (LMWH).
Receiving anticancer therapy for an active malignancy or MF including chemotherapy, radiation therapy, hormonal therapy such that at least 5 half-lives of that medication is completed at least 7 days prior to the first dose of study drug or within 30 days prior to first dose of study drug, whichever is shorter, and during the study treatment period (other than any overlapping therapy as part of the selected BAT).
