A randomized, open-label, single-visit, crossover study simulating triple-drug delivery with Ellipta compared with dual inhaler combinations in patients with COPD.

ABSTRACT: Background:Administering maintenance COPD therapy with a combination of multiple inhalers may increase inhaler errors. This study evaluated the potential benefits of using a single Ellipta dry powder inhaler (DPI) compared with two combinations of DPIs commonly used to deliver triple maintenance therapy. Methods:Patients receiving inhaled COPD medication were enrolled in this multicenter, randomized, open-label, placebo-device, crossover study with a 2×2 complete block design (NCT0298218), which comprised two substudies: Ellipta vs Diskus + HandiHaler (substudy 1) or Turbuhaler + HandiHaler (substudy 2). Patients demonstrated inhaler use after reading the relevant patient information leaflet (PIL). A trained investigator assessed user errors (critical errors [errors likely to result in no or significantly reduced medication being inhaled] and overall errors). The primary endpoint was the proportion of patients making ?1 critical error after reading the PIL. The secondary endpoints included error rates during ?2 reassessments following investigator instruction (if required), instruction time, and patient preference. Results:After reading the PIL, significantly fewer patients made critical errors with Ellipta compared with Diskus + HandiHaler (9% [7/80] vs 75% [60/80], respectively; P<0.001) or Turbuhaler + HandiHaler (9% [7/79] vs 73% [58/79], respectively; P<0.001). The number of patients making overall errors was also lower with Ellipta vs tested inhaler combinations (P<0.001 for each substudy). The median instruction time needed for error-free use was shorter with Ellipta in substudies 1 and 2 (2.7 and 2.6 minutes, respectively) vs either combination (10.6 [Diskus + HandiHaler] and 11.3 minutes [Turbuhaler + HandiHaler], respectively). Significantly more patients preferred Ellipta over Diskus + HandiHaler or Turbuhaler + HandiHaler overall for taking their COPD medication (81% vs 9% and 84% vs 4%, respectively) and per the number of steps for taking their COPD medication (89% vs 8% and 91% vs 5%, respectively). Conclusion:Fewer patients with COPD made critical errors with the single DPI, and patients required less instruction time, compared with each dual DPI combination.

Project description:Medications for respiratory disorders including asthma and chronic obstructive pulmonary disease (COPD) are typically delivered to the lung by means of a handheld inhaler. Patient preference for and ability to use the inhaler may influence their adherence to maintenance therapy, and adherence may affect treatment outcomes. In this study, patient experience of using a dry powder inhaler (DPI), the ELLIPTA™ DPI, in clinical trials of a new maintenance therapy for asthma and COPD was investigated. The ELLIPTA DPI has been designed to contain two separate blister strips from which inhalation powder can be delivered, and to be simple to use with a large, easy-to-read dose counter.Semi-structured, in-depth, qualitative interviews were carried out 2-4 weeks after patients had completed one of six phase IIIa clinical trials using the ELLIPTA DPI. Interview participants were asked about their satisfaction with various attributes of the inhaler and their preference for the ELLIPTA DPI relative to currently-prescribed inhalers, and responses were explored using an inductive content analysis approach. Participants also rated the performance of the inhaler on several criteria, using a subjective 1-10 scale.Participants with asthma (n = 33) and COPD (n = 42) reported high levels of satisfaction with the ELLIPTA DPI. It was frequently described as straightforward to operate and easy to use by interview participants. Ergonomic design, mouthpiece fit, and dose counter visibility and ease of interpretation emerged as frequently cited drivers of preference for the ELLIPTA DPI compared with their current prescribed inhaler. Of participants with asthma, 71% preferred the ELLIPTA DPI to DISKUS™ and 60% to metered dose inhalers. Of participants with COPD, 86% preferred the ELLIPTA DPI to DISKUS, 95% to HandiHaler™, and 85% to metered dose inhalers. Overall average performance scores were >9 (out of 10) in participants with asthma and COPD.The ELLIPTA DPI was associated with high patient satisfaction and was preferred to other inhalers by interview participants with asthma and COPD. The development of an inhaler that is regarded as easy and intuitive to use may have positive implications for adherence to therapy in asthma and COPD.

Project description:IntroductionInhalation therapy involves two types of adherence: adherence to the drug and adherence to the procedures for the inhalation device. User satisfaction and preference are key factors for maintaining good adherence of both types, and they should be evaluated based on three conditions being well maintained: asthma control level (ACL), adherence, and adequate device operability during usage duration. We compared user satisfaction and preference between a pressurized metered-dose inhaler (pMDI) and a dry powder inhaler (Ellipta), while maintaining the three conditions during usage in stable asthma patients.MethodsIn this open-label, randomized, two-way crossover study, patients with stable asthma [Asthma Control Questionnaire (ACQ) scores < 0.75] were classified into a 20-64-year age group (G1) and a ≥ 65-year age group (G2) and randomly assigned to either a formoterol/fluticasone combination (FFC) as the pMDI group or a vilanterol/fluticasone combination (VFC) as the Ellipta group. Satisfaction and preference levels were evaluated at week 4. ACL was measured using the ACQ and Japan Asthma Control Survey questionnaires at weeks 0 and 4. Device operability and respiratory resistance were also examined.ResultsForty-four patients (23 G1, age 45.8 ± 1.9 years; 21 G2, 74.1 ± 1.3 years) were enrolled and maintained good ACL during the study. Adherence to FFC pMDI and VFC Ellipta was > 97% in all groups. Device operability did not differ significantly between FFC pMDI and VFC Ellipta in the G1 (p = 0.189) or G2 (p = 0.506) group. Overall satisfaction was marginally higher with the FFC pMDI than with the VFC Ellipta in G2 (p = 0.012) but non-significantly different in G1 (p = 0.733). Factors affecting overall satisfaction in G2 were difference of inhalation device and body mass index. Respiratory resistance did not change significantly over the study in G2.ConclusionBased on maintaining good ACL, adherence, and device operability, FFC pMDI showed significantly higher satisfaction and preference levels than VFC Ellipta in elderly persons.Trial registrationJapan Registry of Clinical Trials identifier, jRCTs041180001 (registered 21 August 2018).
