A Study to Test Whether Nerandomilast Can Help Slow Down Changes in the Lung in People With a Family History of Pulmonary Fibrosis
What this study is about
This study is open to people aged 40 years or older who have at least 1 family member with pulmonary fibrosis. Pulmonary fibrosis is a condition where lung tissue becomes scarred, making it harder to breathe. People can join if a lung scan shows early changes in the lung, called interstitial lung abnormalities, which may lead to lung scarring.
View original scientific description
This study is open to people aged 40 years or older who have at least 1 family member with pulmonary fibrosis. Pulmonary fibrosis is a condition where lung tissue becomes scarred, making it harder to breathe. People can join if a lung scan shows early changes in the lung, called interstitial lung abnormalities, which may lead to lung scarring. People with family members who have pulmonary fibrosis are more likely to develop it themselves. That is why it is important to check early for lung changes and find ways to prevent the condition from getting worse. The purpose of this study is to find out whether a medicine called nerandomilast can help slow down changes in the lung in people with a family history of pulmonary fibrosis. Participants are put into one of 2 groups randomly, which means the group is chosen by chance. One group takes nerandomilast tablets, and the other group takes placebo tablets. Placebo tablets look like nerandomilast tablets but do not contain any medicine. Participants take a tablet twice a day for about 2 to 3 years. There is a 3 out of 5 chance that participants will receive nerandomilast instead of the placebo. Participants are in the study for about 2 to 3 years. Participants visit the study site multiple times: more frequently during the first 2 years (about every 3 months), and then every 6 months thereafter. In the 3rd year, participants also have phone calls with the site staff every 3 months. Doctors regularly test lung function and take chest scans to see if the treatment works. The results are compared between the 2 groups to see if nerandomilast helps. The doctors also check participants' health and take note of any unwanted effects.
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
- Individuals ≥40 years of age at the time of first signed informed consent at Visit 1a
- Participants must have at least 1 first-degree relative (biological parent, sibling, or child) with confirmed pulmonary fibrosis (idiopathic pulmonary fibrosis \[IPF\], idiopathic nonspecific interstitial pneumonia \[NSIP\], and/or pulmonary fibrosis due to known genetic cause \[e.g. short telomere syndrome, mucin 5B (MUC5B) mutation, surfactant protein mutations\])
- High resolution computed tomography (HRCT) scan with evidence of interstitial lung abnormalities involving at least 5% of a single lung zone or interstitial lung disease (ILD), based on central evaluation
- Forced vital capacity (FVC) ≥80% of predicted normal at Visit 1b
- Diffusing capacity of the lungs for carbon monoxide (DLCO) corrected for hemoglobin ≥70% of predicted normal at Visit 1b Further inclusion criteria apply.
Exclusion criteria
- Prior known pulmonary fibrosis that, in the opinion of the Investigator, requires treatment with approved therapies
- Prebronchodilator forced expiratory volume in 1 second (FEV1)/FVC \<0.7 at Visit 1b
- HRCT findings consistent with probable or definite usual interstitial pneumonia (UIP) pattern
- Any medical condition that is known to predispose to the development of pulmonary fibrosis (e.g. known connective tissue disease)
- Prior or current use of nerandomilast, nintedanib, or pirfenidone Further exclusion criteria apply.

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.
