proportion of
subjects with gout flares requiring treatment were low and similar in all groups
through the study. Mean (SE) rates of gout flares requiring treatment from the
end of Month 6 to the end of Month 12 were 0.58 (0.10) for allopurinol alone
versus 0.57 (0.10) and 0.51 (0.09), respectively, in the lesinurad 200 mg +
allopurinol and lesinurad 400 mg + allopurinol groups
