Assessment of Continuous Positive Airway Pressure Therapy in IPF

Study Purpose

The purpose of this study is to evaluate whether biomarkers of lung injury and remodeling are responsive to effective continuous positive airway pressure (CPAP) treatment in adults with idiopathic pulmonary fibrosis (IPF) and moderate-to-severe obstructive sleep apnea (OSA).

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, 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.

The disease, disorder, syndrome, illness, or injury that is being studied.

Interstitial Lung Disease, Obstructive Sleep Apnea
Additional Details

Idiopathic pulmonary fibrosis (IPF) is a progressive fibrotic disease of the peripheral lung parenchyma that affects 0.5% of older adults in the U.S. and confers a very poor median survival. Repetitive injury to the lung with abnormal healing likely results in fibrosis as treatment of those risk factors that cause these injuries may improve outcomes. Obstructive sleep apnea (OSA), a form of sleep disordered breathing, is highly prevalent in adults with IPF and may be a risk factor in IPF by exerting peripheral tractional stress on the lung and promoting oxidative injury by intermittent hypoxia. Effective treatment of OSA with continuous positive airway pressure (CPAP) reduces the number of obstructive events in OSA and therefore may reduce repetitive injury to the lung in adults with IPF. Participants in this study will undergo polysomnography to determine whether they have OSA, and if so, its severity based on the apnea-hypopnea index (AHI, events/ hour). Those participants with moderate-to-severe OSA will undergo CPAP treatment for up to 48 weeks with an interim period of withdrawal of CPAP. The primary aim of this study will examine the effect of CPAP treatment and its withdrawal and re-initiation on biomarkers of lung injury and remodeling in adults with IPF and moderate-to-severe OSA who are adherent to CPAP (expected sample size for this group is 30). The study will stop enrollment after 30 participants in this group are enrolled.
