A Multicenter Prospective Study of Risk Factors in Progressive Pulmonary Fibrosis

Study Purpose

The goal of this observational study is to learn about risk of progressive pulmonary fibrosis (PPF). The main questions it aims to answer are:

  • - Risk factors of PPF.
  • - Prevalence of PPF.
  • - Mortality of PPF.
Patients with interstitial lung disease (ILD) of known or unknown etiology other than IPF who has radiological evidence of pulmonary fibrosis will enroll in this study.
  • - All participants will have baseline investigations at the first visit having provided informed consent.
  • - At the first visit, baseline characteristics will be collected including demographics, medical history, smoking history, complications and medication use.
50 mL of blood will be obtained. High resolution computed tomography (HRCT), full lung function tests and a 6 min walk test will be performed.
  • - Further visits at 6 months and 12 months will include further 50 mL blood sampling.
HRCT, full lung function tests and a 6 min walk test will be repeated.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.
