Description

Summary

This is a randomized, double-blind, placebo-controlled, repeat-dose, multicenter trial. Participants will be screened within 6 weeks prior to the Baseline (Day 1) Visit. Approximately 300 participants who meet the trial eligibility criteria will be randomized on Day 1 in a 1:1:1 ratio to receive HZN-825 300 mg QD, HZN-825 300 mg BID or placebo for 52 weeks.

The trial will include up to a 42-day Screening Period and a 52-week Double-blind Treatment Period. Participants will take their first dose of trial drug at the clinic and will participate in trial visits at Week 4 and every 6 weeks thereafter until Week 52.

All participants who complete the Double-blind Treatment Period (Week 52) will be eligible to enter a 52-week extension trial (HZNP-HZN-825-302, NCT05626751). Participants not entering the extension trial will participate in a Safety Follow-up Visit 4 weeks after the last dose of trial drug.
