Cohort of IPF Patients Experiencing an Exacerbation

Study Purpose

Extension of the PFBIO cohort which includes patients with newly diagnosed idiopathic pulmonary fibrosis (IPF) for longitudinal follow-up for up to 5 years. In the PFBIO-EXA extension, patients are included if they experience an exacerbation, or other increase in respiratory symptoms requiring hospital admission, for further collection of clinical and biological data.

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.

Eligible Ages 18 Years and Over
Gender All
More Inclusion & Exclusion Criteria

Inclusion Criteria:

Trial Details

Trial ID:

This trial id was obtained from, 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.

Additional Details

The aim of this study is to investigate the diagnostic and prognostic value of blood biomarkers during exacerbations, or other increase in respiratory symptoms requiring hospital admission in patients with IPF. Patients that are already included in the PFBIO-cohort (NCT02755441) and who are admitted to hospital with an increase in respiratory symptoms, are also included in PFBIO-EXA. Patients are recruited within 24 hrs. from hospital admission with respiratory worsening, where clinical data, and blood samples are collected. The blood samples are investigated for the same blood biomarkers as PFBIO. Patient related outcomes are also collected, including quality-of-life questionnaires and outcomes of the exacerbations.

Arms & Interventions



All patients recruited for PFBIO-EXA from the original PFBIO cohort are included into the cohort.
