Evaluation of FeNO During and Following Acute COPD Exacerbation - Full Text View

Purpose

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.

Secondary Endpoint: Change in Slow Vital Capacity
Change in FEV1/SVC from Day 0 to the end of the study [ 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. ]
Secondary Endpoint: Change in the ratio of FEV1 to Slow Vital Capacity
Change in COPD Assessment Test (CAT) Responses from Day 0 to the end of the study [ 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. ]
Secondary Endpoint: Change in the responses on the CAT

Other Outcome Measures:

Evaluation of FEV1/FVC, FEV1, FEF25-75, FEF50, PEF and Inspiratory Capacity By FeNO Level at Baseline [ 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. ]
• Other endpoint - the secondary endpoints will be evaluated by FeNO level at baseline as follows:
- FeNO ≤ 25 ppb versus FeNO > 25 ppb
- FeNO <50 ppb versus FeNO ≥ 50 ppb
- FeNO > 25 ppb and FeNO < 50 ppb versus FeNO<25 and versus FeNO ≥ 50 ppb

Detailed Description:

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.
