About this study

People affected by pulmonary fibrosis (PF) currently have limited treatment options to slow the progression of disease. New research studies are needed to gain valuable knowledge about potentially better treatment options.

The Fibroneer trial is a randomised controlled trial, designed to see if a medicine called BI 1015550 can help people with PF-ILD. The aim is to understand if the study drug affects scarring, inflammation and slows the rate of lung function decline.

PF-ILD is a group of progressive fibrotic interstitial lung diseases, that includes diagnoses such as: fibrotic hypersensitivity pneumonitis (fHP), rheumatoid arthritis interstitial lung disease (RA-ILD), and many others.


What is involved?

Patients will be randomly assigned to one of three groups, by chance. Participants will not know which group they have been assigned to until the end of the study. Patients who are assigned to 2 of the groups will be given different doses of BI 1015550 (either a higher or lower dose). Patients will take a tablet twice per day. Patients who are in the third group will receive a placebo. Patients in this group will still  take tablets twice per day, however these tablets will not contain any of the BI 1015550 study drug.

Patients will be asked to take part in the trial for up to two and a half years. Throughout the first year, patients will visit the study location 10 times.  After the first year, study visits will be once every 3 months. During these visits various test will be carried out, including blood tests, lung function tests and completing questionnaires.

Summary of involvement

Participation for up to 2.5 years

10 assessments during the first year and 3-monthly thereafter

Taking a study drug or placebo

Medical assessments

Patient surveys

Can I take part?

You may be eligible to take part if you are aged 40 years or older and have a diagnosis of progressive fibrotic ILD (PF-ILD). If you have IPF and would like to take part, please follow this link:

If you are already receiving treatment in the form of nintedanib or pirfenidone, you can continue taking this throughout the trial.

In research studies, there are lots of different reasons why you may or may not be able to take part. These are known as inclusion and exclusion criteria (see list below). Only the research team will be able to fully determine whether you are able to take part in the study. You can withdraw at any point.

If you are not able to take part in this research study, there may be other opportunities for you to take part in different studies.

To find our more about other research opportunities visit our research finder main page.

You may be able to join this study if all of these apply:

Aged 40 years or over

Diagnosis of PF-ILD


On stable therapy with nintedanib or pirfenidone for at least 12 weeks prior to the first assessment


Not receiving treatment with nintedanib or pirfenidone for at least 8 weeks prior to the first assessment

Forced Vital Capacity (FVC) more than 45% of predicted normal at the first assessment

You will not be able to join the study of any of the following applies:

Not having a diagnosis of PF-ILD

Other clinically significant lung changes

An acute exacerbation within 3 months before the first assessment

Confirmed infection of COVID-19 which is not fully recovered within 4 weeks before randomisation.

What difference could taking part make?

Taking part in the Fibroneer clinical trial will help researchers to identify the potential effects of a new study drug. The study will help to gain greater understanding of the medication and if it has the potential to help reduce the progression of lung scarring.

Where does the study take place?

Study locations







Multiple study centres across the UK are currently recruiting patients. Patients who do not live locally to a trial site may still be eligible to take part.
