A Study to Find Out Whether BI 765423 Has an Effect on Lung Function in People With Idiopathic Pulmonary Fibrosis (IPF) With or Without Standard Treatment
What this study is about
This study is open to adults who are at least 40 years old and have idiopathic pulmonary fibrosis (IPF). People can participate in the study if they have a forced vital capacity (FVC) greater than or equal to 45% of the predicted value and fibrosis of 20% or more confirmed by a high-resolution computed tomography (HRCT) scan.
View original scientific description
This study is open to adults who are at least 40 years old and have idiopathic pulmonary fibrosis (IPF). People can participate in the study if they have a forced vital capacity (FVC) greater than or equal to 45% of the predicted value and fibrosis of 20% or more confirmed by a high-resolution computed tomography (HRCT) scan. The purpose of this study is to find out if a medicine called BI 765423 can improve lung function in people with IPF.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- : 1. 40 years of age or older at the time of informed consent signature. 2.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
