Satisfaction with the Use of eFlow Closed-System Nebulizer in Patients with Moderate-to-Very Severe Chronic Obstructive Pulmonary Disease: Findings from a Long-Term Safety Study.

ABSTRACT

BACKGROUND: Effective delivery of inhaled drugs in chronic obstructive pulmonary disease (COPD) depends on patients' ability to correctly use an inhalation device. Nebulized delivery may be appropriate for COPD patients who cannot coordinate breath with inhalation or generate adequate inhalational force. Until recently, long-acting muscarinic antagonists (LAMAs), used for maintenance treatment of COPD, were available for delivery only via handheld inhalers. Lonhala™ Magnair™ (glycopyrrolate inhalation solution) is a LAMA delivered via the eFlow® closed-system (eFlow CS) vibrating membrane nebulizer. We assessed patient-reported ease of use and satisfaction with the eFlow CS nebulizer in the GOLDEN (Glycopyrrolate for Obstructive Lung Disease via Electronic Nebulizer)-5 study. METHODS: GOLDEN-5, a phase 3, randomized, open-label trial, evaluated the safety and efficacy of glycopyrrolate/eFlow CS 50 µg twice daily versus tiotropium 18 µg once daily (administered via HandiHaler™) in patients with moderate-to-very severe COPD. Only patients in the glycopyrrolate/eFlow CS group completed a study-specific device use questionnaire, evaluating patients' perceptions about ease of use, confidence in drug delivery, and overall device satisfaction at week 48 or end of study. Responses were summarized by counts and percentages. RESULTS: Of 620 patients who received glycopyrrolate/eFlow CS, 454 completed the questionnaire (mean age [standard deviation, SD] 63.3 [8.5] years; mean BMI [SD] 28.45 [6.208] kg/m2). Based on patient-reported perceptions, most patients (83%) were "confident" to "very confident" that the drug was delivered into their lungs with the eFlow CS; >70% rated the eFlow CS as "easy" or "very easy" to assemble, operate, and clean. Most (75%) patients ranked themselves as being "satisfied" or "very satisfied" overall with the eFlow CS nebulizer. CONCLUSIONS: High levels of satisfaction, confidence, and ease of use were reported with the eFlow CS nebulizer in this study. These findings support the use of the eFlow CS for maintenance treatment of COPD with glycopyrrolate inhalation solution.
