Trial Outcomes & Findings for Study of the Safety and Effectiveness of Rilonacept for the Prevention of Gout Flares (NCT NCT00610363)

NCT ID: NCT00610363

Last Updated: 2017-05-02

Results Overview

A gout flare was defined as participant reported acute articular pain typical of a gout attack that required treatment with an anti-inflammatory therapeutic: had at least 3 of the following 4 signs or symptoms: joint swelling, tenderness, redness, and pain and with at least 1 of the following: rapid onset of pain, decreased range of motion, joint warmth or other symptoms similar to a prior gout flare. Number of gout flares per participant was reported for this outcome measure. For drop-outs, only flares occurred before Day 84 were counted, regardless whether the flares occurred during the treatment period or not.

PRIMARY outcome

Timeframe: Day 1 (Baseline) to Day 84 (Week 12)

Population: Full analysis set (FAS) that included all randomized participants who received any study medication and was based on treatment allocated by IVRS at randomization (as randomized).

A gout flare was defined as participant reported acute articular pain typical of a gout attack that required treatment with an anti-inflammatory therapeutic: had at least 3 of the following 4 signs or symptoms: joint swelling, tenderness, redness, and pain and with at least 1 of the following: rapid onset of pain, decreased range of motion, joint warmth or other symptoms similar to a prior gout flare. Number of gout flares per participant was reported for this outcome measure. For drop-outs, only flares occurred before Day 84 were counted, regardless whether the flares occurred during the treatment period or not.

SECONDARY outcome

Timeframe: Day 1 (Baseline) to Day 84 (Week 12)

Population: Full analysis set (FAS) that included all randomized participants who received any study medication and was based on treatment allocated by IVRS at randomization (as randomized).

Participants were asked to complete a telephone diary by calling the IVRS daily beginning at the baseline visit (Day 1) through the follow-up visit (Day 154) and reported their general well-being, gout symptoms, and weekly study drug administrations. At the onset of pain from a gout flare, participants were to answer additional diary questions regarding their gout flare and had to continue daily flare assessments until they reported the flare had ended. If a flare occurred just prior to the follow-up visit (Day 154), participants were to continue completing the daily diary until the flare resolved. Gout flare pain was assessed on a scale from 0 to 10 (with 0=no pain and 10=severe pain) within the past 24 hours.
