This study is open to adults with Progressive Fibrosing Interstitial Lung Diseases (PF-ILDs). People who have a form of PF-ILD other than Idiopathic Pulmonary Fibrosis (IPF) can join the study. If they already take nintedanib, they can continue treatment throughout the study.

The purpose of this study is to find out whether a medicine called BI 1015550 helps people with PF-ILD. Participants are put into 3 groups randomly, which means by chance. Participants in 2 groups take different doses of BI 1015550 as tablets twice a day. Participants in the placebo group take placebo tablets twice a day. Placebo tablets look like BI 1015550 tablets but do not contain any medicine.

Participants are in the study for up to two and a half years. During the first year, they visit the study site 10 times. Afterwards, they visit the study site every 3 months. The doctors regularly test participants' lung function. The results of the lung function tests are compared between the groups. The doctors also regularly check participants' health and take note of any unwanted effects.

Inclusion Criteria

Patients ≥18 years old at the time of signed informed consent
Signed and dated written informed consent in accordance with ICH-GCP and local legislation prior to admission to the trial
Diagnosis of progressive fibrosing ILD other than IPF (physician confirmed)
Patients may be either
on a stable therapy _with nintedanib for at least 12 weeks prior to Visit 1 and during screening and are planning to stay on this background treatment after randomization. (_ stable therapy is defined as a tolerated regimen of nintedanib (with no dose changes) for at least 12 weeks)
not on treatment with nintedanib for at least 8 weeks prior to Visit 1 and during the screening period (e.g. either Antifibrotic (AF)-treatment naïve or previously discontinued) and do not plan to start or re-start antifibrotic treatment
Forced Vital Capacity (FVC) ≥45% of predicted normal at Visit 1
DLCO corrected for Hemoglobin (Hb) [Visit 1] ≥25% and <90% predicted of normal at Visit 1
Women of childbearing potential (WOCBP) must be ready and able to use highly effective methods of birth control. Of note, oral hormonal contraceptives are not considered a highly effective method due to potential drug-drug interactions
Patients treated with permitted immunosuppressive agents for an underlying systemic disease (e.g. Methotrexate (MTX), Azathioprine (AZA)) need to be on a stable treatment for at least 12 weeks prior to Visit 1 and during the screening period

Exclusion Criteria

Relevant airways obstruction (prebronchodilator Forced Expiratory Volume in 1 second (FEV1)/Forced vital capacity (FVC) <0.7) at Visit 1
In the opinion of the Investigator, other clinically significant pulmonary abnormalities
Acute Interstitial Lung Disease (ILD) exacerbation within 3 months prior to Visit 1 and/or during the screening period (investigator-determined)
Relevant chronic or acute infections including human immunodeficiency virus (HIV) and viral hepatitis
Patients having developed ILD due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection/coronavirus disease 2019 (COVID-19) within 12 months of screening (based on investigators judgement)
Major surgery (major according to the investigator's assessment) performed within 6 weeks prior to Visit 2 or planned during the trial period, e.g. hip replacement. Registration on lung transplantation list would not be considered as planned major surgery
Any documented active or suspected malignancy or history of malignancy within 5 years prior to Visit 1, except appropriately treated basal cell carcinoma of the skin, in situ squamous cell carcinoma of the skin or in situ carcinoma of uterine cervix
Aspartate aminotransferase (AST) or Alanine Aminotransferase (ALT) >2.5 x upper limit of normal (ULN) or total Bilirubin >1.5 x ULN at Visit 1
Further exclusion criteria apply
