Outcomes
Primary outcome [1] 291796 0
Efficacy [Baseline to Week 24]]
To compare the efficacy of two dose-schedule arms of pacritinib (pooled once-daily and twice-daily dosing arms) with that of Best Available Therapy in patients with thrombocytopenia and primary myelofibrosis, post-polycythemia vera myelofibrosis, or post-essential thrombocythemia myelofibrosis; the efficacy measure for this analysis is the proportion of patients achieving a greater than 35% reduction in spleen volume from baseline to week 24 by magnetic resonance imaging (MRI) or computed tomography (CT) and the proportion of patients achieving a greater than 50% reduction in total symptom score from baseline to Week 24 as measured by the Myeloproliferative Neoplasm Symptom Assessment Form 2.0.

Summary
Brief summary
This study will compare the chemotherapy drug, Pacritinib, against the best available treatment for Thrombocytopenia and Myelofibrosis. You may be eligible to join this study if you aged 18 years or above and have been diagnosed with thrombocytopenia and/or myelofibrosis. Participants in this study are randomly allocated (by chance) to one of three groups. Participants in the first group will receive one dose of 400mg of oral Pacritinib for 24 weeks or until progression has occurred. Participants in the second group will receive two doses of 200mg of oral Pacritinib daily for up to 24 weeks or until progression occurs. Participants in the third group will receive best available treatment - which will be chosen by your treating physician. Participants will undergo magnetic resonance imaging (MRI) or computed tomography (CT) scans to determine spleen volume and will be assessed for total symptom score using the Myeloproliferative Neoplasm Symptom Assessment Form 2.0. These assessments will occur 12 weekly. Patients may crossover from the BAT (Best available treatment) arm to Pacritinib at the discretion of the Investigator.
