A Single Center, Open Label, Prospective Study Measuring Proportion of Patients With Suboptimal Peak Inspiratory Flow Rate (sPIFR) Over 24 Weeks in an Ambulatory Setting Among Moderate to Very Severe COPD Patients
In Brief
A clinical study evaluating Home PIFR monitoring with InCheck Dial for COPD. Completed, enrolled 80 participants across 1 site.
Detailed Summary
Recent studies have reported that some Chronic Obstructive Pulmonary Disease (COPD) patients may have a suboptimal ability to generate a sufficient inspiratory effort to achieve adequate lung delivery of inhaled medications through dry powder inhalers. Sparse data is available about the inspiratory capacity of these patients in the home setting, whether clinically stable or when experiencing worsened respiratory symptoms outside the acute care setting. This study is undertaken to better understand the proportion of patients with suboptimal peak inspiratory flow rate (sPIFR) measurements amongst COPD patients receiving dry powder inhaler(s) (DPI) in the ambulatory setting. Further, the study will characterize PIFR over time, the variability of PIFR measurements, and the associations with potential predictors (demographics, clinical, Patient-Reported Outcomes (PRO), body position, and device) as well as exacerbations frequency and change in PIFR around period of exacerbation.
