What is the study measuring?

Primary Outcome Measures

Outcome Measure	Time Frame
Numbers of acute gout flares	12 weeks

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Numbers of acute gout flares		24 weeks
Proportions of subjects with at least 1 acute gout flare		12 weeks
Proportions of subjects with at least 1 acute gout flare		24 weeks
Time from randomization to first acute flare.		24 weeks
Duration of acute gout flares.		12 weeks
Duration of acute gout flares.		24 weeks
Subject's overall assessment of response to treatment	Response to treatment will be assessed by the subjects using a five-point Likert scale: 1-very good, 2-good, 3-fair, 4-poor, and 5-very poor.	24 weeks
Investigator's overall assessment of response to treatment	Response to treatment will be assessed by the Investigators using a five-point Likert scale: 1-very good, 2-good, 3-fair, 4-poor, and 5-very poor.	24 weeks
36-item Short Form Survey (SF-36)	36-Item Short Form Survey (SF-36) will be used to assess the health and functional changes of the subjects. It comprises 36 items that measure perceived health on eight scales (i.e., physical functioning, physical role, bodily pain, general health, vitality, social functioning, emotional role, and mental health) with higher scores (range 0-100) reflecting better perceived health.	24 weeks
Adverse events (AE)		24 weeks
