Plain-language summary

Adults 40 years of age and older with idiopathic pulmonary fibrosis (IPF) or 18 years and older with progressive pulmonary fibrosis (PPF) can participate in this study. Only people who have a chronic cough can take part. The purpose of this study is to find out how well BI 1839100 helps reduce coughing in people with IPF or PPF. Participants who have IPF are put into 4 groups by chance. Participants in 3 groups get different doses of BI 1839100. Participants in 1 group get placebo. Placebo looks like BI 1839100 but does not contain any medicine. Participants take the treatment for 3 months. After 1 month of treatment, participants who take the highest dose will have coughing measured to find out if the medicine works. If it does not work, the study may be stopped. Participants who have IPF are in the study for slightly longer than 4 months. During this time, they visit the study site 7 times. This study will also measure the effects of BI 1839100 on coughing and lung function in a smaller group of people with PPF. During the study, coughing is measured over 24 hours about once per month using a portable device given to participants to use during the study. Participants fill in questionnaires about their coughing. Doctors also perform breathing tests that measure how well the lungs are working at the site visits. Researchers compare the results between participants who take BI 1839100 and placebo. The doctors also regularly check participants' health and take note of any unwanted effects.

Inclusion Criteria For Idiopathic Pulmonary Fibrosis (IPF) cohort: * Minimum age: 40 years * Diagnosis of IPF * Chronic cough (\>8 weeks prior to Visit 1) attributed to IPF and refractory to treatment for known causes (Principal Investigator (PI) assessment) * Cough Severity visual analogue scale (VAS) ≥30 mm at Visit 1 and Visit 2B * Forced vital capacity (FVC) ≥45% of predicted normal at Visit 1 * Diffusing capacity of the lungs for carbon monoxide (DLCO) \>25% of predicted normal at Visit 1 * Patients may be either: * On stable therapy with nintedanib or pirfenidone for ≥12 weeks prior to Visit 1 and are planning to stay on this background treatment for the whole trial duration. Combination of nintedanib plus pirfenidone will not be allowed * Not on therapy with nintedanib or pirfenidone for ≥12 weeks prior to Visit 1 (either antifibrotic (AF)-treatment naïve or previously discontinued) and do not plan to start or re-start AF treatment during the trial. It is not permitted to delay nintedanib or pirfenidone therapy for the purpose of participating in this trial * Patients aged ≥40 years when signing the informed consent For Progressive Pulmonary Fibrosis (PPF) cohort: * Minimum age: 18 years * Diagnosis of PPF * Chronic cough (\>8 weeks prior to Visit 1) attributed to PPF, refractory to treatment for known causes (PI assessment) * Cough Severity VAS ≥30 mm at Visit 1 and Visit 2B * FVC ≥45% of predicted normal at Visit 1 * DLCO ≥25% of predicted normal at Visit 1 …
