- Palpable splenomegaly ≥ 5 cm on physical examination
- Total Symptom Score ≥ 13 on the MPN-SAF TSS 2.0, not including the inactivity question
- Patients who are platelet or red blood cell transfusion-dependent are eligible
- Adequate white blood cell counts (with low blast counts), liver function, and renal function
- At least 6 months from prior splenic irradiation
- At least 1-4 weeks since prior myelofibrosis therapy, including any erythropoietic or thrombopoietic agent
- Not pregnant, not lactating, and agree to use effective birth control
- Able and willing to undergo frequent MRI or CT assessments and complete symptom assessments using a patient-reported outcome instrument Exclusion Criteria:
