A Phase 3 Study of Pacritinib in Patients With Primary Myelofibrosis, Post Polycythemia Vera Myelofibrosis, or Post-Essential Thrombocythemia Myelofibrosis (PACIFICA)
A Randomized, Controlled Phase 3 Study of Pacritinib Versus Physician's Choice in Patients With Primary Myelofibrosis, Post Polycythemia Vera Myelofibrosis, or Post-Essential Thrombocythemia Myelofibrosis With Severe Thrombocytopenia (Platelet Count <50,000/μL)(PACIFICA)
This study (study ID PAC203 North America; PAC303 ex-North America) is evaluating 200 mg BID of pacritinib compared to physician's choice (P/C) therapy in patients with MF and severe thrombocytopenia (platelet count <50,000/μL). Approximately 399 patients in total will be enrolled, randomized 2:1 to either pacritinib (approximately 266 patients) or to P/C therapy (approximately 133 patients)
Condition or disease: Primary Myelofibrosis/Post-Polycythemia Vera Myelofibrosis/ Post-essential Thrombocythemia Myelofibrosis
Intervention/treatment: Drug-Pacritinib

- Any history of CTCAE grade ≥2 cardiac dysrhythmias within 6 months prior to treatment Day 1. Patients with non-corrected QT interval CTCAE grade 2 cardiac dysrhythmias may be considered for inclusion, with the approval of the Medical Monitor, if the dysrhythmias are stable, asymptomatic, and unlikely to affect patient safety.
- QT corrected by the Fridericia method (QTcF) prolongation >450 ms or other factors that increase the risk for QT interval prolongation (eg, hypokalemia [defined as serum potassium <3.0 mEq/L that is persistent and refractory to correction], or history of long QT interval syndrome).

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Pacritinib 200 mg BID
To receive pacritinib 200 mg twice daily (BID) orally, at the same time of day, with or without food
|
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
|
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.
|
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.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Spleen volume
Time Frame: From baseline at 24 weeks
|
To compare the efficacy of pacritinib with that of physician's choice (P/C) therapy, as assessed by the proportion of patients achieving a ≥35% spleen volume reduction (SVR) as measured by magnetic resonance imaging (MRI, preferred) or computed tomography (CT) scans
|
From baseline at 24 weeks
|
Total Symptom Score (TSS) (excluding tiredness)
Time Frame: From baseline at Week 24
|
To compare the efficacy of pacritinib compared to P/C therapy, as assessed by the proportion of patients achieving a ≥50% reduction in Total Symptom Score (TSS).
The TSS is the sum of the individual symptom scores for tiredness, early satiety, abdominal discomfort, night sweats, pruritus, bone pain, and pain under ribs on the left side.
Symptoms are ranked 0 (absent) to 10 (worst imaginable)
|
From baseline at Week 24
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Overall Survival (OS)
Time Frame: until 2.5 years after the date of randomization
|
To compare the overall survival (OS) of patients treated with pacritinib versus those treated with P/C
|
until 2.5 years after the date of randomization
|
Patient Global Impression of Change (PGIC) assessed at Week 24
Time Frame: End of Week 12 to 2 years following Week 24 visit
|
To compare the percentage of patients who self-assess as "very much improved" or "much improved" as measured by the Patient Global Impression of Change (PGIC) in patients treated with pacritinib versus those treated with P/C
|
End of Week 12 to 2 years following Week 24 visit
|
To compare the safety of pacritinib versus P/C therapy
Time Frame: Randomization through 30 after last treatment
|
Safety will be assessed based on the incidence and severity (according to the Common Terminology Criteria for Adverse Events) of treatment emergent adverse events from the time of randomization until 30 days after completion of treatment with pacritinib and/or physician's choice therapy.
|
Randomization through 30 after last treatment
