HZNP-HZN-825-303 (HARBOR) comprises of 2 parts. Part 1 (Core Phase) is a randomized, double-blind, placebo-controlled, repeat-dose, multicenter trial to evaluate the efficacy, safety and tolerability of HZN-825 in participants with Idiopathic Pulmonary Fibrosis (IPF). Part 2 (Extension Phase) is an optional, open-label, repeat-dose, multicenter extension of the Core Phase. The trial will include up to an 8-week Screening Period and a 52-week Double-blind Treatment Period in the Core Phase and 52 weeks of open-label HZN-825 treatment in the Extension Phase. During the Core Phase, participants will be screened within 8 weeks prior to the baseline (Day 1) Visit. Approximately 135 participants who meet the trial eligibility criteria will be randomly assigned in a 1:1:1 ratio on Day 1 to receive HZN-825 300 mg QD, HZN-825 300 mg BID or matching placebo orally for 52 weeks using the following 2 stratification factors: 1. Concomitant use of approved IPF therapy (i.e., nintedanib or pirfenidone): yes or no 2. Forced vital capacity (FVC) % predicted at Baseline: ≥70% or \<70% Participants who complete the 52-week Double blind Treatment Period of the Core Phase of the trial will be invited to extend their participation in the 52-week Extension Phase of the trial.
