A Randomized, Double-blind, Dose-ranging, Placebo-controlled Study to Evaluate the Efficacy and Safety of Bexotegrast (PLN-74809) for the Treatment of Idiopathic Pulmonary Fibrosis (BEACON-IPF)


This is a randomized, double-blind, dose-ranging, placebo-controlled study to evaluate the efficacy and safety of 2 doses of bexotegrast (PLN-74809) [160 and 320 mg] taken for 52 weeks by participants with IPF taking and not taking background therapy (ie, nintedanib or pirfenidone).
