A40 Expiratory Flow Limitation Registry

Status Withdrawn

Clinical Trial Summary

This prospective observational multicenter registry study will include adults greater than 40 years old, diagnosed with chronic obstructive pulmonary disease, requiring home noninvasive ventilation as part of standard medical care. For the purposes of this study, chronic obstructive pulmonary disease is defined as chronic respiratory failure consisting of historical spirometry vales (FEV1 <60% predicted and FEV1/VC < 0.7) and chronic increased daytime carbon dioxide levels greater than 6.0 kPa or 45 mmHg. In addition, participants diagnosed with major organ system diseases or obstructive sleep apnea will be excluded. At least 100 men and women who consent and meet the inclusion/exclusion criteria will be asked to participate. The anticipated study duration will be 6 months. The study will involve an initial visit for the standard of care initiation of home noninvasive ventilation. At this time, potential participants will be screened for participation. If eligible once consented, medical history will be collected and baseline questionnaires related to their respiratory disease will be completed. The registry study will include 6 month of home use of the noninvasive ventilator using the BiPAP A40 EFL device. Study staff will reach out to participants on a monthly basis to review any issues, medication changes, unscheduled visits, and device data download. Additional phone calls and or visits may occur on an as needed basis if issues arise. The final visit will be an in facility visit. The primary endpoint will be the overall prevalence of Expiratory Flow Limitation (EFL) in ventilated hypercapnic COPD patients, as defined as the percentage participants exhibiting a DeltaXrs value greater than or equal to 2.8 during one or more nights of therapy.

Clinical Trial Description

Prospective observational multicenter registry study for chronic obstructive pulmonary disease patients who require noninvasive ventilation in the home setting as part of standard medical care. The registry includes one in person screening or baseline visit, monthly follow-up phone calls (monitoring for medication changes, unscheduled visits and adverse events) and device data downloads, and a final in person study visit. ;
