    Idiopathic pulmonary fibrosis (IPF) is a disease of unknown etiology that is characterized by the insidious development of lung fibrosis ultimately leading to distortion of the lung architecture, respiratory failure, and death. IPF is one of aseveral collectionentities associated with pulmonary fibrosis called the idiopathic interstitial pneumonias (IIP). Based on the histopathologic features of severethe fibrotic process, it is possible to identify four distinct entities: usual interstitial pneumonia (UIP) (synonymous with IPF), nonspecific interstitial pneumonia (NSIP), desquamative intersti [...] [...]

    Study First Submitted

  • Stopped: an ongoing trial was terminated, suspended or withdrawn.
  • Notable: the trial’s plan changed such as a big move in its timeline or size, a new primary endpoint, sponsor or phase, or recruiting opened or resumed.
  • Minor: routine progress and housekeeping, such as sites added or enrollment closed.
The purposes of this study are: * to determine if there are specific genetic traits that might explain why patients have developed pulmonary fibrosis; * to determine if specific genetic traits account for differing patterns of inflammation and scar tissue that has formed in the patient's lungs.
