Study Summary

This is a Phase 4, multicenter, open-label trial of pegloticase with methotrexate (MTX) in adult participants with uncontrolled gout who were previously treated with pegloticase without a concomitant immunomodulator and stopped pegloticase due to failure to maintain serum uric acid (sUA) response and/or a clinically mild infusion reaction (IR). Approximately 30 participants will be enrolled. Pegloticase + MTX will be administered for approximately 24 weeks, with an optional extension up to 48 weeks. The trial design will include 5 distinct components: 1. Screening Period, lasting up to 42 days; 2. 6-week MTX Tolerability Assessment Period (hereafter referred to as the MTX Run-in Period); 3. 24-week Pegloticase + MTX Treatment Period, which will include a Week 24/End of Trial/Early Termination Visit (subjects that end MTX and pegloticase treatment prior to the Week 24 will remain on trial for follow up until the Week 24 visit) 4. Optional Pegloticase + MTX Extension Period up to 24 weeks 5. 30-Day Post Treatment Follow -up

Primary Outcome

An sUA responder is defined as a participant achieving and maintaining sUA \<6 mg/dL for at least 80% of the time during Month 6 (Weeks 20, 21, 22, 23 and 24).
