500-Patient study aims to unlock secrets of progressive lung scarring
NCT ID NCT06855329
First seen Jun 26, 2026 · Last updated Aug 19, 2026 · Updated 2 times
Summary
This study follows 500 adults with progressive pulmonary fibrosis (a type of lung scarring) for 24 months. Researchers will collect medical images, lung function tests, and blood samples to better classify the disease and predict its course. The goal is to improve how doctors identify and manage this condition, not to test a new drug.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to better ways to identify and predict progressive pulmonary fibrosis, helping doctors tailor treatments earlier.
- What could go wrong
- This is an observational study, not testing a treatment, so it won't directly change patient care. Results may take years to influence practice.
This is an AI summary of the original study and may miss details. Read our disclaimer.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age 18-80 years with a diagnosis of non-IPF fibrosing ILD due to CTD-ILD, fHP, or non-IPF IIP based on central review * Diagnosis of Fibrotic ILD as determined by site investigator. * Willingness to comply with study procedures and follow-up. * Provide written informed consent. Exclusion Criteria: * Site diagnosis of fibrosing ILD \>5 years prior to Visit 1 (Screening and Baseline Visit). * Minimal ILD, defined as reticular opacities and/or ground-glass opacities without architectural distortion (traction bronchiolectasis/bronchiectasis or honeycombing) affecting \< 5% of the lung on centralized evaluation of HRCT at Visit 1 (Screening and Baseline Visit). High quality historical chest HRCT may be used if performed within 90 days prior to Visit 1. * Extent of emphysema \>15% of total lung volume or greater than extent of fibrosis based on central, qualitative assessment of HRCT at Visit 1. High quality historical chest HRCT may be used if performed within 90 days prior to Visit 1. * Active malignancy within one year prior to Visit 1 (except for non-melanoma skin cancer requiring local treatment). * Inability to complete full PFT (spirometry and DLCO) at Visit 1. Historical PFT may be used if performed within 90 days prior to Visit 1. * Taking nintedanib or nerandomilast at Visit 1. * Pregnancy at screening or plans to become pregnant during follow-up. * Participation in an interventional clinical trial for fibrotic ILD at the time of Visit 1, or receipt of an investigational drug within the previous 4 weeks of the enrollment visit (Visit 1) or 5 times the half-life, if longer.
