A Study to Investigate Leramistat in Patients With IPF

This will be a Phase 2, double-blind, placebo-controlled, 2-arm, parallel-group, multi-centre study to investigate leramistat treatment of patients aged 40 years or older with IPF. The study is planned to consist of the following parts: Screening period: 1 to 28 days (Weeks -4 to -1). Treatment period: a 12-week blinded, placebo-controlled treatment period (Weeks 1 to 12). Follow up period: 56 days (Weeks 13 to 20). All participants will return for a follow-up visit 56 days after their final dose. Randomization will be stratified by concomitant use of an approved anti-fibrotic drug (nintedanib or pirfenidone) at randomization versus no concomitant use of an approved anti-fibrotic drug at randomization. Number of Participants: Approximately 150 participants will be enrolled and randomly assigned in a 2:1 ratio to receive either leramistat or matched placebo. If the participant is receiving nintedanib or pirfenidone treatment, it should be stable for at least 8 weeks prior to study entry and be predicted to remain stable during the course of the study. The maximum duration of participation (including screening period and follow-up) is 24 weeks. Data Monitoring/Other Committee: A DSMB has been appointed for this study.
