Evaluation of FeNO During and Following Acute COPD Exacerbation

Wake Forest University10 enrolled

Overview

The purpose of this research study is to determine whether exhaled nitric oxide (FeNO) goes up during an acute exacerbation of Chronic Obstructive Pulmonary Disease (AECOPD) and whether the level of exhaled nitric oxide returns to normal in the weeks after an exacerbation.

The purpose of this research study is to determine whether exhaled nitric oxide (FeNO) goes up during an acute exacerbation of COPD and whether the level of exhaled nitric oxide returns to normal in the weeks after an exacerbation. FeNO is measured with a medical device called the NIOX MINO®. The NIOX MINO® device has been cleared by the Food and Drug Administration (FDA) for use in children and adults age 7 and older to measure Fractional Exhaled Nitric Oxide (FeNO) in human breath.This information will be useful for determining whether FeNO may help predict the development of a COPD exacerbation and/or be useful for identifying patients who will have a beneficial therapeutic response to inhaled or systemic corticosteroids during a COPD exacerbation.

Outcomes

Primary Outcomes

Change in FeNO from Day 0 to the end of the study

Time frame: Time points for measurement of the Primary Endpoint will be between Day 0 (considered baseline) and Visit 2/Day 14, Visit 3/Day 28 and Visit 4/Day 56.

Secondary Outcomes

Change in FEV1/FVC from Day 0 to the end of the study

Secondary Endpoint: Change in proportion of a person's vital capacity that they are able to expire in the first second of expiration (FEV1/FVC)

Time frame: Time points for measurement of the Secondary Endpoints will be between Day 0 (considered baseline) and Visit 2/Day 14, Visit 3/Day 28 and Visit 4/Day 56.

Change in FEV1 from Day 0 to the end of the study

Secondary Endpoint: Change in Forced Expiratory Volume at one second (FEV1)

Time frame: Time points for measurement of the Secondary Endpoints will be between Day 0 (considered baseline) and Visit 2/Day 14, Visit 3/Day 28 and Visit 4/Day 56.

Change in FEF25-75 from Day 0 to the end of the study

Secondary Endpoint: Change in Forced Expiratory Flow at the 25% point to the 75% point (FEF25-75)

Time frame: Time points for measurement of the Secondary Endpoints will be between Day 0 (considered baseline) and Visit 2/Day 14, Visit 3/Day 28 and Visit 4/Day 56.

Change in PEF from Day 0 to the end of the study

Secondary Endpoint: Change in Peak Expiratory Flow (PEF)

Time frame: Time points for measurement of the Secondary Endpoints will be between Day 0 (considered baseline) and Visit 2/Day 14, Visit 3/Day 28 and Visit 4/Day 56.

Change in Inspiratory Capacity from Day 0 to the end of the study

Secondary Endpoint: Change in Inspiratory Capacity
