A Randomised, Double-blind, Placebo-controlled Phase IIa Trial to Evaluate the Efficacy, Pharmacokinetics, Pharmacodynamics, Safety, and Tolerability of BI 3810477 With or Without Standard of Care in Patients With Idiopathic Pulmonary Fibrosis

Summary

This study is for adults aged 40 and older who have idiopathic pulmonary fibrosis (IPF). Women can only participate if they cannot get pregnant. The purpose of this study is to find out whether a medicine called BI 3810477 can slow down the worsening of lung function in people with IPF. Participants are put into 2 groups randomly, which means by chance. One group receives BI 3810477 and the other group receives placebo. Placebo looks like BI 3810477 but does not contain any medicine. Participants receive BI 3810477 or placebo for 12 weeks. Participants may continue their regular treatment for IPF during the study. Participants are in the study for about 6 to 7 months. During this time, they visit the study site regularly, about 18 times. Some of the visits may be done at the participant's home instead of the study site. Doctors regularly test how well the lungs work by doing lung function tests. They also look at lung scans and measure markers in the blood that are linked to lung health. The results are compared between the 2 groups to see whether BI 3810477 works. The doctors also regularly check participants' health and note any unwanted effects.
