A Study to Find Out Whether BI 1015550 Improves Lung Function in People With Idiopathic Pulmonary Fibrosis (IPF)

• Status: Not yet recruiting
• Trial end date: 2025-02-28
• Target enrollment: 0
• Participant gender: All

Summary

This study is open to adults with a lung disease called Idiopathic Pulmonary Fibrosis (IPF). People can join the study if they are 40 years or older. If they already take nintedanib or pirfenidone for their IPF, 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 IPF.

Participants are put into 2 groups randomly, which means by chance. One group takes BI 1015550 tablets twice a day. The other group takes 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.

Criteria

Inclusion criteria:

1. Written Informed Consent consistent with ICH-GCP and local laws signed prior to entry into the study (and prior to any study procedure including shipment of high-resolution computed tomography (HRCT) to reviewer).

2. Patients (male/female) with a diagnosis of Idiopathic Pulmonary Fibrosis (IPF), aged ≥ 40 years when signing the informed consent. IPF diagnosis based on 2018 ATS/ERS/JRS/ALAT Guideline as confirmed by the investigator based on chest HRCT scan taken within 12 months of Visit 1 and if available surgical lung biopsy; AND Usual interstitial pneumonia (UIP) or probable UIP HRCT pattern consistent with the clinical diagnosis of IPF, as confirmed by central review prior to Visit 2.

3. Patients need to be either

-- on a stable therapy* with nintedanib or pirfenidone for at least 12 weeks prior to Visit 1 and during screening and planning to stay on this background treatment after randomization. Combination of nintedanib plus pirfenidone is not allowed.

[*stable therapy is defined as the individually and general tolerated regimen of either nintedanib or pirfenidone (no dose changes) for at least 12 weeks] OR

-- not on a therapy with nintedanib or pirfenidone for at least 8 weeks prior to Visit 1 or during the screening period. (e.g. either antifibrotic (AF)-treatment naïve or previously discontinued) and start or re-start of an antifibrotic is not planned.

4. Forced Vital Capacity (FVC) ≥ 45% of predicted normal at Visit 1

5. Diffusing capacity for carbon monoxide (DLCO) corrected for Haemoglobin (Hb) [visit 1] ≥ 25% and <90% predicted of normal at Visit 1

6. Female and male patients: Women of childbearing potential (WOCBP) and men able to father a child must be ready and able to use highly effective methods of birth control per ICH M3 (R2) that result in a low failure rate of less than 1% per year when used consistently and correctly. A list of contraception methods meeting these criteria and instructions on the duration of their use is provided in the patient information

Key exclusion criteria

1. Relevant airways obstruction (pre-bronchodilator Forced Expiratory Volume (FEV)1/FVC < 0.7) at Visit 1.

2. In the opinion of the Investigator, other clinically significant pulmonary abnormalities.

3. Acute IPF or Interstitial Lung Disease (ILD) exacerbation within 3 months prior to screening and/or during the screening period (investigator-determined).

4. Lower respiratory tract infection requiring antibiotics within 4 weeks prior to Visit 1 and/or during the screening period.

5. Relevant chronic or acute infections including human immunodeficiency virus (HIV) and viral hepatitis and a confirmed infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) within the 4 weeks prior to Visit 1 or during the screening period.

A patient can be re-screened if the patient was treated and/or cured from the acute infection.,

6. 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, "under surveillance" prostate cancer or in situ carcinoma of uterine cervix.

7. Major surgery (major according to the investigator's assessment) performed within 3 months prior to Visit 1 or planned during the course of the trial. Being on a transplant list is allowed.

8. Aspartate amino transferase (AST) or Alanine amino transferase (ALT) > 2.5 x upper limit of normal (ULN) or total Bilirubin > 1.5 x ULN at Visit 1.

Further exclusion criteria apply.
