Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Pacritinib
Treatment: Drugs - Physician's Choice medications

Experimental: Pacritinib 200 mg BID - To receive pacritinib 200 mg twice daily (BID) orally, at the same time of day, with or without food

Active comparator: Physician's Choice (P/C) therapy - The Physician's Choice (P/C) therapy (limited to single drugs from the following list: corticosteroids, hydroxyurea, danazol, or low-dose ruxolitinib). The proposed P/C regimen for a patient must be selected prior to randomization.


Treatment: Drugs: Pacritinib
Oral administration. Supplied in capsules containing 100 mg (as the free base) in red cap/gray body size 0 opaque hard gelatin capsules. The inactive ingredients are microcrystalline cellulose, magnesium stearate, and polyethylene glycol 8000. Each capsule contains 146 mg of pacritinib citrate, which is equivalent to 100 mg pacritinib free base

Treatment: Drugs: Physician's Choice medications
Physician's Choice medications will be selected and administered according to the investigator's judgement. Investigators can select individual P/C agents but cannot combine agents or give them sequentially.
