In Brief

A Phase 4 clinical trial evaluating Pegloticase and Methotrexate (MTX) for Uncontrolled Gout and Chronic Gout. Completed, enrolled 54 participants across 12 sites.

Detailed Summary

This trial is to assess efficacy, safety, blood levels and bodily effects of up to 2 dose levels of intravenous (IV) pegloticase (KRYSTEXXA) infusions at every 4 week intervals (Q4 Weeks) for up to 6 months (Day 1 to 24 weeks with an optional 24 - 48 weeks treatment duration) when given in combination with weekly oral doses of methotrexate (MTX).
