Study 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.

Primary Outcome

Symptoms of polycythemia vera were assessed using a modified Myeloproliferative Neoplasm Symptom Assessment Form (MPN-SAF) electronic diary. Using the diary, patients rated the following symptoms on a scale from 0 (absent) to 10 (worst imaginable): tiredness, itching, muscle aches, night sweats, and sweats while awake. The total symptom score ranged from 0-50 and was calculated as the sum of the 5 symptom scores. A higher score indicates worse symptoms.
