This study aimed to determine the feasibility and acceptability of telemedicine among patients with COPD and physicians and facility staff in Japan.Methods: This was a 52-week multicenter, prospective, single-arm, feasibility and acceptability cohort study of Japanese patients ≥ 40 years of age with COPD or asthma-COPD overlap. Participants underwent training to use YaDoc, a telemedicine smartphone App, which included seven daily symptom questions and weekly COPD Assessment Test (CAT) questions. The primary endpoint was participant compliance for required question completion. The secondary endpoint was participant and physician/facility staff acceptability of YaDoc based on questionnaires completed at Week 52. The impact of the Japanese COVID-19 pandemic state of emergency on results was also assessed.Results: Of the 84 participants enrolled (mean age: 68.7 years, 88% male), 72 participants completed the study. Completion was high in the first six months but fell after that. Median (interquartile range [IQR]) compliance for daily questionnaire entry was 66.6% (31.0– 91.8) and 81.0% (45.3– 94.3) for weekly CAT entry. Positive participant responses to the exit questionnaire were highest regarding YaDoc ease of use (83.8%), positive impact on managing health (58.8%), and overall satisfaction (53.8%). Of the 26 physicians and facility staff enrolled, 24 completed the study. Of these, the majority (66.7%) responded positively regarding app facilitation of communication between physicians and participants to manage disease. Compliance was similar before and after the first COVID-19 state of emergency in Japan.Conclusion: Daily telemedicine monitoring is potentially feasible and acceptable to both patients and physicians in the management of COPD. These results may inform potential use of telemedicine in clinical practice and design of future studies.Clinical Trial Registration: JapicCTI-194916.Keywords: Japan, patient-reported outcome measure, feasibility, acceptability, telemonitoring, smartphone

Here we present findings from the Japanese subgroup of KRONOS.Methods: Patients received BGF MDI 320/18/9.6μg, glycopyrrolate/formoterol fumarate (GFF) MDI 18/9.6μg, budesonide/formoterol fumarate (BFF) MDI 320/9.6μg, or budesonide/formoterol fumarate dry powder inhaler (BUD/FORM DPI) 400/12μg twice-daily for 24 weeks. The primary endpoint was the change from baseline in morning pre-dose trough forced expiratory volume in 1 s (FEV1) over Weeks 12–24. Symptoms, quality of life, exacerbations, and safety were also assessed.Results: In total, 416 Japanese patients (21.9% of the global KRONOS population) were randomized and treated with BGF MDI (n=139), GFF MDI (n=138), BFF MDI (n=70), or BUD/FORM DPI (n=69). Nominally significant improvements in the change from baseline in morning pre-dose trough FEV1 over Weeks 12–24 were observed for BGF MDI vs GFF MDI (least squares mean [LSM] difference 37 mL, 95% confidence interval [CI] 3, 72; P=0.0337) and BFF MDI (67 mL; 95% CI 25, 109; P=0.0020). Treatment with BGF MDI led to a nominally significant reduction in the rate of moderate/severe exacerbations vs GFF MDI (rate ratio 0.40, 95% CI 0.19, 0.83; P=0.0142). Compared with dual therapies, numerical improvements were observed with BGF MDI for Transition Dyspnea Index focal score and the change from baseline in Evaluating Respiratory Symptoms in COPD total score (P≤0.3899). All treatments were generally well tolerated.Conclusion: BGF MDI nominally significantly improved lung function and numerically improved symptoms vs GFF MDI and BFF MDI. BGF MDI nominally significantly reduced exacerbations vs GFF MDI in Japanese patients with COPD. Efficacy and safety findings were generally comparable to those in the global KRONOS population.Keywords: co-suspension delivery technology, ICS/LAMA/LABA, inhaled corticosteroid, long-acting muscarinic antagonist, long-acting β2-agonist, Japan

The long-term safety of triple therapy for COPD has not been investigated in Japanese patients. In this 28-week extension study (NCT03262012), we investigated the long-term safety and tolerability of BGF MDI in Japanese patients with moderate-to-very severe COPD who completed the 24-week Phase III randomized, double-blind, multicenter KRONOS study (NCT02497001).Materials and methods: Patients randomized to BGF MDI 320/18/9.6 μg, glycopyrrolate/formoterol fumarate (GFF) MDI 18/9.6 μg, budesonide/formoterol fumarate (BFF) MDI 320/9.6 μg, or budesonide/formoterol fumarate dry powder inhaler (BUD/FORM DPI) 400/12 μg twice-daily in KRONOS continued treatment for up to 28 additional weeks. Safety was evaluated over 52 weeks via adverse event (AE) monitoring, electrocardiograms, clinical laboratory testing, and vital sign measurements.Results: The safety population included 416 patients who received BGF MDI (n=139), GFF MDI (n=138), BFF MDI (n=70), or BUD/FORM DPI (n=69). Treatment-emergent AE (TEAE) rates were similar across treatment groups (range: 82.6–82.9%). The most frequent TEAEs overall were nasopharyngitis (32.2%) and bronchitis (9.9%). The incidence of major adverse cardiovascular events was low across groups (range: 0.0–2.9%). Over 52 weeks, the incidence of confirmed pneumonia was 9.4% (BGF MDI), 3.6% (GFF MDI), 5.7% (BFF MDI), and 2.9% (BUD/FORM DPI); in the 28-week extension period, rates were comparable across groups (range: 2.9–5.7%). Six deaths were reported (0.7–2.2% per group); none were considered treatment-related. No clinically meaningful trends were observed in electrocardiograms, laboratory parameters, or vital signs over time in any of the treatment groups.Conclusion: All treatments were well tolerated over 52 weeks, and the safety profile of BGF MDI was generally comparable to dual long-acting muscarinic antagonist (LAMA)/long-acting β2-agonist (LABA) and inhaled corticosteroid (ICS)/LABA therapies. These findings support the long-term tolerability of BGF MDI in Japanese patients with COPD.Keywords: co-suspension delivery technology, ICS/LAMA/LABA, inhaled corticosteroid, long-acting muscarinic antagonist, long-acting β2-agonist, Japan

Osamu Hataji,1 Masahiro Naito,1 Kentaro Ito,1 Fumiaki Watanabe,1 Esteban C Gabazza,2 Osamu Taguchi31Respiratory Center, Matsusaka Municipal Hospital, Tonomachi, 2Department of Immunology, 3Department of Pulmonary and Critical Care Medicine, Mie University Graduate School of Medicine, Mie, JapanBackground: The current mainstay of therapy for chronic obstructive pulmonary disease (COPD) is long-acting bronchodilators. To date, the effect of indacaterol, a β2-agonist, on activities of daily living in COPD patients is not well understood. The aim of this study was to evaluate the efficacy of indacaterol with regard to activities of daily living in patients with COPD.Methods: In this nonrandomized open-label study, 23 patients with COPD were instructed to carry an accelerometer for 4 weeks without indacaterol therapy and then for another period of 4 weeks while receiving indacaterol therapy.Results: The number of steps, duration of moderate or greater physical activity, and energy expenditure were significantly increased after treatment with indacaterol compared with baseline data in all patients with COPD; the metabolic equivalent of task was also significantly enhanced after treatment with indacaterol.Conclusion: This study provides early evidence that indacaterol improves daily physical activity in patients with COPD.Keywords: chronic obstructive pulmonary disease, indacaterol, long-acting β2-agonist, physical activity
