There is one clinical trial.
This is one of two replicate randomized, double-blind, placebo-controlled, parallel arm trials to determine the safety and efficacy of two different dose levels of SEL-212 compared to placebo. Approximately 105 patients, stratified as to the presence or absence of tophi, will be randomized in a 1:1:1 allocation ratio prior to Baseline to receive treatment with one of two dose levels of SEL-212 or placebo every 28 days for approximately 6 months in each trial (SEL-212/301 and SEL-212/302). Analysis of efficacy will be performed at Day 28 of Treatment Period 6. Safety will be monitored throughout the study.
