Longitudinal study without an investigational medicinal product in patients with Progressive Fibrosing Interstitial Lung Disease (PF-ILD) to evaluate novel imaging-based biomarkers in comparison with lung function for use in early clinical development

The main objectives of the study are to assess the annual lung function change in patients with progressive fibrosing interstitial
lung disease (PF-ILD) including idiopathic pulmonary fibrosis (IPF), with Usual Interstitial Pneumonia (UIP) or probable UIP CT pattern,
and to monitor lung structural changes.
