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
In Brief
A Phase 3 clinical trial evaluating Ruxolitinib, Hydroxyurea (HU), and 2 other interventions for Polycythemia Vera. Completed, enrolled 110 participants across 70 sites in 7 countries.
Detailed Summary
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.

Interventions
Ruxolitinib will be orally self-administered at a starting dose of 10 mg (two 5 mg tablets) twice a day. Dose increases of 5 mg (1 tablet) in twice-daily increments are permitted after 4 weeks and again after 8 weeks of therapy for subjects who meet prespecified criteria for inadequate efficacy.
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 prespecified criteria.
All placebo will be self-administered, and dosing will be the same as with the blinded dose. When adjustments are made to the ruxolitinib dose, the dose of HU-placebo will be adjusted concurrently.
