Switch Study From Hydroxyurea to Ruxolitinib for RELIEF of Polycythemia Vera Symptoms: The Relief Study
Polycythemia Vera Symptom Study Evaluating Ruxolitinib Versus Hydroxyurea in a Randomized, Multicenter, Double-Blind, Double-Dummy, Phase 3 Efficacy and Safety Study of Patient Reported Outcomes

The purpose of the RELIEF study is to compare symptoms in polycythemia vera (PV) subjects treated with ruxolitinib versus subjects treated with hydroxyurea (HU) as measured by the percent of subjects who achieve a clinically meaningful symptom improvement (ie, total symptom score reduction of ≥ 50% reduction) at Week 16 compared to Baseline. The study is also designed to demonstrate that these responses are durable with continued treatment.

This is a Phase 3 multicenter, double-blind, double-dummy, randomized study. Only subjects with PV who have received HU for at least 12 weeks, have been receiving a stable dose before screening and still have symptoms related to PV will be enrolled.

Subjects will be randomized (1:1) to 1 of 2 treatment arms:

A: ruxolitinib and HU-placebo B: HU and ruxolitinib-placebo

Subjects randomized to either arm may be eligible to transition to open-label ruxolitinib after Week 16.

Interventional
Phase 3
Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Polycythemia Vera
  • Drug: ruxolitinib
    Ruxolitinib will be self-administered at a starting dose of 10 mg (two 5 mg tablets) twice a day by mouth. Doses increases of 5 mg (1 tablet) in twice daily increments are permitted after 4 weeks and again after 8 weeks of therapy.
  • Drug: hydroxyurea (HU)
    Hydroxyurea (500 mg capsules) will be orally self-administered at the dose that the subject was receiving previously. The dose may be increased after 4 weeks and again after 8 weeks of therapy to optimize efficacy for subjects meeting pre-specified criteria.
  • Drug: placebo
    All placebo will be self-administered and dosing will the same as with the blinded dose and comparator arm.
  • Experimental: ruxolitinib and hydroxyurea (HU)-placebo
    Interventions:
    • Drug: ruxolitinib
    • Drug: placebo
  • Active Comparator: HU and ruxolitinib-placebo
    Interventions:
    • Drug: hydroxyurea (HU)
    • Drug: placebo
