PREventative Study Against URate-Lowering Drug-Induced Gout Exacerbations (PRE-SURGE 2)

March 20, 2017 updated by: Regeneron Pharmaceuticals

A Multi-Center, Randomized, Double-Blind, Placebo Controlled Study of the Efficacy and Safety of Rilonacept for the Prophylaxis of Gout Flares During the Initiation of Allopurinol Therapy

The purpose of this clinical research study was to determine the safety and effectiveness of an experimental drug called rilonacept in participants with gout who are beginning allopurinol treatment for gout. Participants will participate in this study for approximately 22 weeks. Rilonacept was being studied for use in preventing allopurinol-induced gout flares.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 80 years (ADULT, OLDER_ADULT)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Gout Flares Per Participant Assessed From Day 1 to Day 113 (Week 16)
Time Frame: Day 1 to Day 113 (Week 16)
Gout flare was defined as 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.
Day 1 to Day 113 (Week 16)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Modified Gout Flares Per Participant From Day 1 to Day 113 (Week 16)
Time Frame: Day 1 to Day 113 (Week 16)
Modified gout flare was defined using modified definition of a gout flare as participant-reported articular pain typical of a gout attack that was deemed to require treatment with anti-inflammatory therapy. Number of modified gout flares per participant were reported for this outcome measure.
Day 1 to Day 113 (Week 16)
Percentage of Participants With at Least One Flare From Day 1 to Day 113 (Week 16)
Time Frame: Day 1 to Day 113 (Week 16)
Gout flare was defined as 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. Percentage of participants with at least one gout flare was reported for this outcome measure.
Day 1 to Day 113 (Week 16)
Percentage of Participants With at Least Two Flares From Day 1 to Day 113 (Week 16)
Time Frame: Day 1 to Day 113 (Week 16)
Gout flare was defined as 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. Percentage of participants with at least two gout flares was reported for this outcome measure.
Day 1 to Day 113 (Week 16)
Number of Gout Flare Days Per Participant From Day 1 to Day 113 (Week 16)
Time Frame: Day 1 to Day 113 (Week 16)
Gout flare was defined as 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 flare days per participant was reported for this outcome measure.
Day 1 to Day 113 (Week 16)
Number of Gout Flare Days With Participant's Pain Score of 5 or More (From Daily Diary) Per Participant From Day 1 to Day 113 (Week 16)
Time Frame: Day 1 to Day 113 (Week 16)
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 141) 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 141), 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.
Day 1 to Day 113 (Week 16)

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
