This Phase 1b trial is a double-blind, placebo-controlled, multiple ascending dose study to evaluate the safety and tolerability of oral ORIN1001 at 25 mg, 50 mg or 100 mg administered daily for up to 28 days in adult subjects with idiopathic pulmonary fibrosis (IPF) alone or in conjunction with local Standard of Care for IPF (pirfenidone or nintedanib). A maximum of 24 evaluable subjects will be required to complete the study. The study will consist of 3 dose cohorts each enrolling a maximum of 8 subjects randomized either to the active (5 subjects) group or placebo (3 subjects) group. Each subject will receive daily oral doses of ORIN1001 or placebo for 28 days. The safety and pharmacokinetic profile will be evaluated in this study and will include cardiovascular and pulmonary endpoints.
