Brief Summary

The goal of this observational study is to identify early biomarkers that can predict the development of progressive pulmonary fibrosis (PPF) in participants with interstitial lung diseases (ILDs). The participant population includes adults diagnosed with idiopathic pulmonary fibrosis (IPF), familial pulmonary fibrosis (FPF), other fibrotic ILDs, and interstitial lung abnormalities (ILA). The main questions it aims to answer are:

  • What biomarkers and risk factors are linked to fibrosis progression or can predict rapid worsening and sudden flare-ups in IPF and FPF patients?
  • What biomarkers and risk factors can predict the development of a PPF phenotype in different types of ILD?
  • What biomarkers and risk factors can help identify ILA patients who may develop significant ILD?
  • What biomarkers and risk factors can predict how well ILD patients will respond to treatment? Researchers will compare the outcomes between participants diagnosed with IPF/FPF, other fibrotic ILDs, and ILA to see if early detection biomarkers differ among these groups. Participants will:
  • Undergo blood sampling.
  • Perform lung function tests.
  • Have CT scans.
  • Perform breath analysis
  • Participate in exposome and microbiome analyses.
  • Complete questionnaires.
  • A subgroup of participants will be offered bronchoscopy.

Outcome Measures

Primary Outcomes (7)

  • Inflammatory and fibrosis extent assessed by HRCT

    High-Resolution Computed Tomography (HRCT) is an advanced imaging technique used to obtain detailed images of the lungs and chest. Unlike standard CT scans, HRCT uses thin slices and special algorithms to produce high-resolution images that provide more precise visualization of lung structures, making it particularly useful for diagnosing and evaluating various lung conditions. The Inflammatory and Fibrosis extent will be analyzed by using artificial intelligence software.

    A baseline HRCT scan will be performed during screening. Following inclusion in the study, HRCT scans will be repeated annually, starting one year after the initial scan, and continuing each year until the end of follow-up (at 5 years))

  • Pulmonary function tests (PFTs)- Spirometry volumes

    Pulmonary function tests (PFTs) are a group of tests that measure how well your lungs are working. These tests assess lung volume, capacity, rates of flow, and gas exchange. We will look at the following values: 1\. Spirometry Values * Forced Vital Capacity (FVC): The total amount of air exhaled after taking the deepest breath possible. * Forced Expiratory Volume in 1 Second (FEV1): The amount of air forcefully exhaled in one second.

    It will be measured at baseline, at 3, 6, and 12 months, and every other year till end of follow-up (60months))

  • Pulmonary function tests (PFTs)- DLCO measurement

    Pulmonary function tests (PFTs) are a group of tests that measure how well your lungs are working. These tests assess lung volume, capacity, rates of flow, and gas exchange. We will look at the Diffusion Capacity Tests (DLCO). DLCO: Measures how well oxygen and CO2 are exchanged between the lungs and the blood.

    It will be measured at baseline, at 3, 6, and 12 months, and every other year till end of follow-up (60months))

  • Pulmonary function tests (PFTs)- Lungvolume measurement

    Pulmonary function tests (PFTs) are a group of tests that measure how well your lungs are working. These tests assess lung volume, capacity, rates of flow, and gas exchange. We will look at the Lung Volumes and Capacities * Total Lung Capacity (TLC): The total volume of air in the lungs after taking the deepest breath. * Residual Volume (RV): The amount of air left in the lungs after a full exhalation. * Functional Residual Capacity (FRC): The amount of air remaining in the lungs after normal exhalation. * Inspiratory Capacity (IC): The maximum amount of air that can be inhaled after a normal exhalation.

    It will be measured at baseline, at 3, 6, and 12 months, and every other year till end of follow-up (60months))

  • Biomarkers related to pulmonary fibrosis will be measured in plasma and serum

    Blood will be taken from participants at the 8 different time points. A predefined panel of biomarkers related to pulmonary fibrosis will be measured in serum/plasma, urine, and, if available, bronchoalveolar lavage fluid. Biomarker levels will be correlated with the time to event (i.e., development of rapid progression or acute exacerbation) to identify biomarkers that predict rapid progression or acute exacerbation, as defined by the criteria by Raghu et al., (2022).

    It will be measured at baseline, at 3, 6, and 12 months, and every other year till end of follow-up (60months))

  • Peripheral blood mononuclear cell (PBMC) populations in blood

    Deep phenotyping of peripheral blood mononuclear cells (PBMCs) and, when available, BAL cells will be performed using flow cytometry, spectral flow, or cyTOF (cytometry by time of flight). A panel of surface and activation markers will define subsets of monocyte and lymphocyte populations. Data will be correlated to the time of the event.

    It will be measured Will be measured at baseline, at 3, 6 months, 12 months, and every other year till end of follow-up (60months)

  • Exhaled breath analysis including volatile organic compounds

    Exhaled breath analysis involves measurements of volatile organic compounds (VOCs) using gas chromatography-mass spectrometry (GC-MS) and electronic sensor detection of exhaled breath compounds in a non-invasive manner (breathing into a device). For all participants, VOCs will be measured using GC-MS (in house GC mass spectrometer)..

    It will be measured at baseline, at 3, 6, and 12 months, and every other year till end of follow-up (60months))

Secondary Outcomes (18)

  • Disease-relevant questionnaires: Exposure Questionnaire

    Questionnaires will be filled in at baseline, at 6, and 12 months, and every other year till end of follow-up (60months))

  • Disease-relevant questionnaires: KBILD questionnaire.

    Questionnaires will be filled in at baseline, at 6, and 12 months, and every other year till end of follow-up (60months))

  • Disease-relevant questionnaires: Modified Medical Research Council Dyspnea score

    Questionnaires will be filled in at baseline, at 6, and 12 months, and every other year till end of follow-up (60months))

  • Disease-relevant questionnaires: Visual analog scale (VAS)

    Questionnaires will be filled in at baseline, at 6, and 12 months, and every other year till end of follow-up (60months))

  • Disease-relevant questionnaires: Fatigue Severity Scale (FSS)

    Questionnaires will be filled in at baseline, at 6, and 12 months, and every other year till end of follow-up (60months))
