Studien-Informationen

Detailed Description:

The study is a randomized, controlled phase 3 study comparing the efficacy of pacritinib with

P/C therapy in patients with PMF, PPV-MF, or PET-MF (Dynamic International Prognostic Scoring

System [DIPSS] risk score of Intermediate-1 to High-Risk), who have had had no or limited

exposure to any JAK2 inhibitor or are JAK2 inhibitor-naive, and who have severe

thrombocytopenia (platelet count <50,000/µL). This study was designed to use the pacritinib

200 mg BID dose, which was determined to be the optimal dose based on dose- and

exposure-response analyses conducted using all available data, including the dosing data from

the previous portion of this study. Patients will be randomized 2:1 to receive pacritinib 200

mg BID or the 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. Randomization will be stratified by prior JAK2 inhibitor

therapy (yes/no) and P/C therapy selected prior to randomization. Prior JAK2 inhibitor

therapy will be defined as any duration of treatment with a JAK2 inhibitor, such as

ruxolitinib, fedratinib, or momelotinib. To be eligible, patients are not allowed to have

been treated with more than one JAK2 inhibitor. Assigned treatment will continue until the

patient experiences progressive disease or intolerable AEs, withdraws consent, or initiates

new MF-directed therapy. No study treatment crossover will be allowed at any time. All

patients should complete all visit procedures through Week 24, including patients who stop

treatment or have protocol-defined progressive disease prior to Week 24, unless the patient

withdraws consent for study procedures, dies, undergoes splenic irradiation or splenectomy,

initiates any non-protocol-directed anti-MF treatment, or the study is terminated. In

addition to the above, patients will be considered to have discontinued treatment if

pacritinib or P/C therapy is held for >28 consecutive days due to treatment toxicity, or if

treatment is discontinued for lack of efficacy, or at the request of the principal

investigator or the patient. Following the Week 24 assessment, patients who are benefiting

from therapy will be allowed to continue receiving the assigned treatment (pacritinib or P/C)

until the patient experiences progressive disease, intolerable AEs, withdraws consent, or

initiates new MF-directed therapy. All randomized patients will be followed for survival for

2.5 years from the date of randomization unless consent for follow-up is withdrawn.

Studien-Rationale

Primary outcome:

1. 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

2. 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)

Secondary outcome:

1. 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

2. 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

3. 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.

Studien-Arme

  • 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.

Geprüfte Regime

  • 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
  • Physician's Choice medications (corticosteroids / hydroxyurea / danazol / low-dose ruxolitinib / ):
    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.
