A Study to Test Whether Nerandomilast Helps People With Lungfibrosis Related to Rheumatic Diseases
What this study is about
Adults 18 years of age and older or above legal age with lung fibrosis related to systemic autoimmune rheumatic disease can participate in this study. People can only take part if they show no improvement in lung function after standard treatment with immunosuppressant medicine.
View original scientific description
Adults 18 years of age and older or above legal age with lung fibrosis related to systemic autoimmune rheumatic disease can participate in this study. People can only take part if they show no improvement in lung function after standard treatment with immunosuppressant medicine. The main purpose of this study is to find out how a medicine called nerandomilast affects the lungs in people with systemic autoimmune rheumatic disease.

Primary outcome measures
Absolute change from baseline in quantitative interstitial lung disease (QILD) score [%] on high-resolution computed tomography (HRCT) at Week 26
Time frame: At baseline and at Week 26
QILD will be assessed via quantitative high-resolution computed tomography (qHRCT). QILD are quantitative measures of different radiological patterns associated with lung fibrosis. QLF is a measure of reticulation with architectural distortion. QGGO is a measure of ground glass opacities (i.e. hazy or cloudy areas) within the lung. QHC is a measure of HC within the lung. QILD is the sum of QLF, QGGO, and QHC. Quantification of HRCT scans will be performed centrally via a machine learning algorithm. QILD \[%\] is the QILD volume \[mL\] as a percent of the total lung volume. A higher QILD percentage or volume indicates a higher extent of disease.
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
- Participant has systemic autoimmune rheumatic diseases associated interstitial lung diseases (SARD-ILD), defined as
- Diagnosis by a rheumatologist with at least 1 of the following SARDs: Rheumatoid arthritis (RA), systemic sclerosis (SSc) (participants must be anticentromere auto-antibody negative), idiopathic inflammatory myopathy (IIM), Sjögren's disease, or Mixed connective tissue disease (MCTD)
- Presence of fibrotic interstitial lung disease (ILD) on high-resolution computed tomography (HRCT), defined as presence of reticular abnormality with traction bronchiectasis with or without honeycombing (HC), with disease extent \>10% on HRCT performed within 12 months of Visit 1 or, if historical scan is not available, on baseline HRCT taken prior to Visit 2, as confirmed by central review

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.
