A Study in People With Idiopathic Pulmonary Fibrosis to Test Whether Pirfenidone Influences the Amount of BI 1015550 in the Blood
United States, Georgia20 participantsStarted 2026-03-05
Plain-language summary
This study is open to adults with idiopathic pulmonary fibrosis (IPF) who are 40 years and older. The purpose of this study is to find out whether a medicine called pirfenidone changes the amount of a medicine called BI 1015550 in the blood. Some people may take more than one medicine at a time. Therefore, it is important to understand how different medicines influence one another.
Participants take one dose of BI 1015550 as a tablet. Participants then take one tablet of pirfenidone 3 times a day for one week. The dose is then increased to 2 tablets 3 times a day for the second week. In the third week the dose is increased further to 3 tablets 3 times a day. Participants then take another dose of BI 1015550 as a tablet.
Participants are in the study for a little over 1 month. During this time, they visit the study site 15 times. Two of the visits include overnight stays at the study site. The study staff also contacts the participants by phone. During the visits, the doctors collect information about participants' health and take blood samples from the participants. They compare the amount of pirfenidone and BI 1015550 in the blood. Doctors also regularly check participants' health and take note of any unwanted effects.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion criteria:
* Male or female patients aged ≥40 years old at the time of signed consent
* Patients with idiopathic pulmonary fibrosis (IPF) and an indication/no contraindication for treatment with pirfenidone based on investigator's judgement.
* Body mass index (BMI) of 18.5 to 29.9 kg/m\^2 (inclusive)
* Signed and dated written informed consent in accordance with International Conference of Harmonization-Good Clinical Practice (ICH-GCP) and local legislation prior to admission to the trial
* Women of childbearing potential (WOCBP) must be ready and able to use highly effective methods of birth control. WOCBP taking oral contraceptives (OC) also have to use one barrier method
Exclusion criteria:
* Patients with a significant disease or condition other than IPF, which in the opinion of the investigator, may put the patient at risk because of participation, interfere with study procedures, or cause concern regarding the patient's ability to participate in the study
* Acute IPF exacerbation within 1 month prior to Visit 1 and/or during the screening period (investigator-determined).
* Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) \>2.5 x ULN or total Bilirubin \>1.5 x upper limit of normal (ULN) at Visit 1
* Patients with underlying liver cirrhosis (Child Pugh C hepatic impairment)
* Cardiovascular diseases, any of the following:
* Severe hypertension (uncontrolled under treatment ≥160/100 mmHg at multiple occasions) within 3 months of Visit 1

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
