RESUMEN

Purpose: To assess patient characteristics of users and new initiators of triple therapy for chronic obstructive pulmonary disease (COPD) in Germany. Patients and Methods: Retrospective cohort study of patients with COPD and ≥1 prescription for single-inhaler triple therapy (SITT; fluticasone furoate/umeclidinium/vilanterol [FF/UMEC/VI] or beclomethasone dipropionate/glycopyrronium bromide/formoterol [BDP/GLY/FOR]) or multiple-inhaler triple therapy (MITT), using data from the AOK PLUS German sickness fund (1 January 2015-31 December 2019). The index date was the first date of prescription for FF/UMEC/VI or BDP/GLY/FOR (SITT users), or the first date of overlap of inhaled corticosteroid, long-acting ß2-agonist, and long-acting muscarinic antagonist (MITT users). Two cohorts were defined: the prevalent cohort included all identified triple therapy users; the incident cohort included patients newly initiating triple therapy for the first time (no prior use of MITT or SITT in the last 2 years). Patient characteristics and treatment patterns were assessed on the index date and during the 24-month pre-index period. Results: In total, 18,630 patients were identified as prevalent triple therapy users (MITT: 17,945; FF/UMEC/VI: 700; BDP/GLY/FOR: 908; non-mutually exclusive) and 2932 patients were identified as incident triple therapy initiators (MITT: 2246; FF/UMEC/VI: 311; BDP/GLY/FOR: 395; non-mutually exclusive). For both the prevalent and incident cohorts, more than two-thirds of patients experienced ≥1 moderate/severe exacerbation in the preceding 24 months; in both cohorts more BDP/GLY/FOR users experienced ≥1 moderate/severe exacerbation, compared with FF/UMEC/VI and MITT users. Overall, 97.9% of prevalent triple therapy users and 86.4% of incident triple therapy initiators received maintenance treatment in the 24-month pre-index period. Conclusion: In a real-world setting in Germany, triple therapy was most frequently used after maintenance therapy in patients with recent exacerbations, in line with current treatment recommendations.


Triple therapy (a combination of three different respiratory inhaled medications) is recommended for patients with chronic obstructive pulmonary disease (COPD) who experience repeated short-term symptom flare-ups when taking dual therapy (a combination of two different respiratory medications). Previously, patients had to take triple therapy using two or three separate inhalers. More recently, single-inhaler triple therapies have been developed, meaning patients can take all three different medications at the same time via one single inhaler. This study assessed the characteristics of patients who were already receiving triple therapy, or who started triple therapy (either via multiple inhalers or a single inhaler), in Germany between January 2015 and December 2019. In total, 18,630 patients who were already receiving triple therapy during the study period, and 2932 patients who newly started using triple therapy were included. The study reported that more than two-thirds of included patients had experienced at least one flare-up of COPD symptoms in the 2 years before starting triple therapy. Most patients had also received another therapy for COPD before starting triple therapy. A small proportion of patients started taking triple therapy after receiving no other therapy for COPD in the previous 2 years. The results of the study suggest that triple therapy for COPD in Germany is most often used in accordance with recommendations (patients already receiving therapy and experiencing repeated symptom flare-ups).

RESUMEN

RATIONALE: The long-acting ß2-agonist/long-acting muscarinic antagonist combination indacaterol/glycopyrronium (IND/GLY) elicits bronchodilation, improves symptoms, and reduces exacerbations in COPD. Magnetic resonance imaging (MRI) of the lung with hyperpolarized gas and gadolinium contrast enhancement enables assessment of whole lung functional responses to IND/GLY. OBJECTIVES: The primary objective was assessment of effect of IND/GLY on global ventilated lung volume (%VV) versus placebo in COPD. Lung function, regional ventilation and perfusion in response to IND/GLY were also measured. METHODS: This double-blind, randomized, placebo-controlled, crossover study assessed %VV and pulmonary perfusion in patients with moderate-to-severe COPD after 8 days of once-daily IND/GLY treatment (110/50 µg) followed by 8 days of placebo, or vice versa, using inhaled hyperpolarized 3He gas and gadolinium contrast-enhanced MRI, respectively. Lung function measures including spirometry were performed for each treatment after 8 days. MEASUREMENTS AND MAIN RESULTS: Of 31 patients randomized, 29 completed both treatment periods. IND/GLY increased global %VV versus placebo (61.73% vs. 56.73%, respectively, least squares means treatment difference: 5.00% [90% CI 1.40 to 8.60]; P = 0.025). IND/GLY improved whole lung index of ventilation volume to perfusion volume (V/Q) ratio versus placebo; 94% (90% CI 83 to 105) versus 86% (90% CI 75 to 97; P = 0.047), respectively. IND/GLY showed a trend to improve diffusing capacity for carbon monoxide (DLCO) (+ 0.66 mL/min/mmHg; P = 0.082). By Day 8, forced expiratory volume in 1 s (FEV1) was increased by 0.32 L versus placebo (90% CI 0.26 to 0.38; P < 0.0001), substantiating earlier findings and providing evidence of assay sensitivity for this trial. CONCLUSIONS: IND/GLY improved lung ventilation assessed by 3He MRI after 1 week of treatment. This observation may provide mechanistic support for the symptomatic clinical benefit shown with IND/GLY in COPD. Clinical trial registered with www.clinicaltrials.gov (NCT02634983).

RESUMEN

BACKGROUND: The aim of this randomized, double-blind trial was to evaluate the safety and tolerability profile, including cardiac safety, of sugammadex-mediated recovery from neuromuscular block in participants undergoing surgery who met the American Society of Anesthesiologists (ASA) Physical Class 3 or 4 criteria. Specifically, this study assessed the impact of sugammadex on cardiac adverse events (AEs) and other prespecified AEs of clinical interest. METHODS: Participants meeting ASA Class 3 and 4 criteria were stratified by ASA Class and NMBA (rocuronium or vecuronium) then randomized to one of the following: 1) Moderate neuromuscular block, sugammadex 2 mg/kg; 2) Moderate neuromuscular block, neostigmine and glycopyrrolate (neostigmine/glycopyrrolate); 3) Deep neuromuscular block, sugammadex 4 mg/kg; 4) Deep neuromuscular block, sugammadex 16 mg/kg (rocuronium only). Primary endpoints included incidences of treatment-emergent (TE) sinus bradycardia, TE sinus tachycardia and other TE cardiac arrhythmias. RESULTS: Of 344 participants randomized, 331 received treatment (61% male, BMI 28.5 ± 5.3 kg/m2, age 69 ± 11 years). Incidence of TE sinus bradycardia was significantly lower in the sugammadex 2 mg/kg group vs neostigmine/glycopyrrolate. The incidence of TE sinus tachycardia was significantly lower in the sugammadex 2 and 4 mg/kg groups vs neostigmine/glycopyrrolate. No significant differences in other TE cardiac arrythmias were seen between sugammadex groups and neostigmine/glycopyrrolate. There were no cases of adjudicated anaphylaxis or hypersensitivity reactions in this study. CONCLUSIONS: Compared with neostigmine/glycopyrrolate, incidence of TE sinus bradycardia was significantly lower with sugammadex 2 mg/kg and incidence of TE sinus tachycardia was significantly lower with sugammadex 2 mg/kg and 4 mg/kg. These results support the safety of sugammadex for reversing rocuronium- or vecuronium-induced moderate and deep neuromuscular block in ASA Class 3 or 4 participants.

RESUMEN

BACKGROUND: For patients with chronic obstructive pulmonary disease (COPD), greater improvements in lung function have been demonstrated for triple versus dual inhaled therapies in traditional spirometry studies. This study was the first to use functional respiratory imaging (FRI), known for increased sensitivity to airway changes versus spirometry, to assess the effect of the inhaled corticosteroid (ICS) component (budesonide) on lung function in patients with moderate-to-severe COPD and a blood eosinophil count > 150 cells/mm3. METHODS: Patients in this Phase IIIb (NCT03836677), randomized, double-blind, crossover study received twice-daily budesonide/glycopyrrolate/formoterol fumarate (BGF) 320/18/9.6 µg fixed-dose triple therapy and glycopyrrolate/formoterol fumarate (GFF) 18/9.6 µg fixed-dose dual therapy over 4 weeks, each delivered via a single metered dose Aerosphere inhaler. Primary endpoints were the improvements from baseline for each treatment in specific (i.e. corrected for lobar volume) image-based airway volume (siVaw) and resistance (siRaw) measured via FRI taken at total lung capacity (Day 29). Secondary outcomes included spirometry and body plethysmography. Adverse events were monitored throughout the study. RESULTS: A total of 23 patients were randomized and included in the intent-to-treat analysis (mean age 64.9 years, 78.3% males, 43.5% current smokers, mean predicted post-bronchodilator forced expiratory volume in 1 s [FEV1] 63.6%). BGF and GFF both statistically significantly increased siVaw from baseline at Day 29 (geometric mean ratio [GM], 95% confidence interval [CI]: 1.72 [1.38, 2.13] and 1.53 [1.28, 1.83], respectively, both p < 0.0001), with a greater increase observed for BGF versus GFF (GM, 95% CI 1.09 [1.03, 1.16], p = 0.0061). Statistically significant reductions in siRaw were also observed with both BGF and GFF (GM, 95% CI 0.50 [0.39, 0.63] and 0.52 [0.40, 0.67], respectively, both p < 0.0001). Additionally, significant improvements from baseline in post-dose FEV1 were observed with BGF and GFF (mean 346 mL, p = 0.0003 and 273 mL, p = 0.0004, respectively). Safety findings were consistent with the known profiles of BGF and GFF. CONCLUSIONS: As observed using FRI, triple therapy with BGF resulted in greater increases in airway volume, and reductions in airway resistance versus long-acting muscarinic antagonist/long-acting ß2-agonist (LAMA/LABA) dual therapy with GFF, reflecting the ICS component's contribution in patients with moderate-to-severe COPD.

RESUMEN

BACKGROUND: We report the long-term effects of triple therapy with budesonide/glycopyrrolate/formoterol fumarate (BGF) vs glycopyrrolate/formoterol fumarate (GFF) and budesonide/formoterol fumarate (BFF) on symptoms and health-related quality of life (HRQoL) over 52 weeks in the Phase III ETHOS study of patients with moderate-to-very severe COPD. METHODS: ETHOS was a randomized, double-blind, multi-center, parallel-group study in symptomatic patients with COPD who experienced ≥1 moderate/severe exacerbation in the previous year. Patients received twice-daily BGF 320/18/9.6 µg, BGF 160/18/9.6 µg, GFF 18/9.6 µg, or BFF 320/9.6 µg, administered via a single Aerosphere inhaler, for 52 weeks. RESULTS: The modified intent-to-treat population included 8509 patients (mean age 64.7 years; 59.7% male; mean COPD Assessment Test score, 19.6). BGF significantly reduced rescue medication use vs GFF and BFF (-0.53 puffs/day [p < 0.0001] and -0.35 puffs/day [p = 0.0002], respectively, with BGF 320 over 52 weeks). BGF 320 also significantly improved St George's Respiratory Questionnaire (SGRQ) total score over 24 and 52 weeks vs dual therapies, resulting in the greatest proportion of SGRQ responders vs dual therapies over 24 weeks (52.5% vs 42.5% [GFF] and 45.2% [BFF]) and 52 weeks (47.0% vs 37.8% [GFF] and 41.0% [BFF]). Similar results were observed with BGF 160. Benefits were also observed vs dual therapies in symptomatic endpoints including Transition Dyspnea Index focal score, EXAcerbations of Chronic pulmonary disease Tool total scores and Evaluating Respiratory Symptoms in COPD total scores over 24 and 52 weeks. CONCLUSIONS: BGF triple therapy improved symptoms and HRQoL vs dual therapies over 24 and 52 weeks in patients with moderate-to-very severe COPD.

RESUMEN

BACKGROUND: In the Phase III KRONOS study, triple therapy with budesonide/glycopyrronium/formoterol fumarate metered dose inhaler (BGF MDI) was shown to reduce exacerbations and improve lung function versus glycopyrronium/formoterol fumarate dihydrate (GFF) MDI in patients with moderate-to-very severe chronic obstructive pulmonary disease (COPD). However, whether the benefits related to the ICS component of BGF are driven by patients with high blood eosinophil counts (EOS) and/or airway reversibility has not been previously studied. METHODS: KRONOS was a Phase III, double-blind, parallel-group, multicenter, randomized, controlled study of patients with moderate-to-very-severe COPD. Patients were randomized 2:2:1:1 to receive BGF 320/14.4/10 µg, GFF 14.4/10 µg, budesonide/formoterol fumarate dihydrate (BFF) MDI 320/10 µg via a single Aerosphere inhaler, or open-label budesonide/formoterol fumarate dihydrate dry powder inhaler 400/12 µg (BUD/FORM DPI; Symbicort Turbuhaler) twice-daily for 24 weeks. Efficacy outcomes included in this post-hoc analysis were change from baseline in morning pre-dose trough FEV1 over weeks 12-24 and the rate of moderate-to-severe and severe COPD exacerbations. Adverse events in the non-reversible subgroup are also reported. RESULTS: Of 1896 patients analyzed, 948 (50%) were non-reversible and had EOS < 300 cells/mm3. In this group, BGF significantly improved morning pre-dose trough FEV1 versus BFF and BUD/FORM (least squares mean treatment difference, 95% confidence interval [CI] 69 mL [39, 99], unadjusted p < 0.0001 and 51 mL [20, 81], unadjusted p = 0.0011, respectively) and was comparable to GFF. BGF also significantly reduced annual moderate-to-severe exacerbation rates versus GFF (rate ratio [95% CI] 0.53 [0.37, 0.76], unadjusted p = 0.0005), with numerical reductions observed versus BFF and BUD/FORM. These results were similar for the overall study population. Safety findings were generally similar between non-reversible patients with EOS < 300 cells/mm3 and the overall population. CONCLUSIONS: In patients with moderate-to-very-severe COPD without airway reversibility and EOS < 300 cells/mm3, BGF significantly improved morning pre-dose trough FEV1 versus BFF and BUD/FORM and significantly reduced the rate of moderate-to-severe exacerbations versus GFF. These findings demonstrate that BGF can provide benefits for a broad range of patients with COPD, and that the overall findings of the KRONOS primary analysis were not driven by patients with reversible airflow obstruction or high eosinophil counts.

RESUMEN

BACKGROUND AND OBJECTIVE: Clinical evidence suggests no clinically relevant pharmacokinetic interactions between indacaterol (IND), glycopyrronium (GLY) and mometasone furoate (MF). A population pharmacokinetic (popPK) analysis was conducted to identify structural models describing systemic pharmacokinetic profiles of IND, GLY and MF, and estimate the effect of covariates on their pharmacokinetics following inhalation as IND/GLY/MF. METHODS: Pharmacokinetic data from 698 patients with asthma were pooled from two Phase III studies that evaluated IND/MF medium- (150/160 µg) and high-dose (150/320 µg), IND/GLY/MF medium- (150/50/80 µg) and high-dose (150/50/160 µg), and a device bridging Phase II study with MF. One popPK model was developed each for IND, GLY and MF using a nonlinear mixed-effect modelling approach. Maximal and trough plasma concentrations were compared across formulations and studies, including data for IND/GLY from chronic obstructive pulmonary disease (COPD) patients. The effect of predefined covariates on the pharmacokinetics of components was evaluated using a full covariate modelling approach. RESULTS: The final pharmacokinetic models were two-compartment disposition models with first-order elimination and sequential zero-order/first-order absorption (IND), with bolus administration and first-order elimination (GLY), and with mixed zero-order/first-order absorption and first-order elimination (MF). All model parameters were estimated with good precision (% relative standard error: IND and MF ≤25%; GLY <10%). No clinically relevant covariate effect was observed on the pharmacokinetics of IND, GLY and MF. IND and GLY pharmacokinetic profiles were similar across different formulations. CONCLUSION: Two-compartment popPK models adequately described the pharmacokinetics of IND, GLY and MF. The effect of covariates was not clinically relevant. The pharmacokinetic profiles of MF were comparable for combination products at corresponding medium- or high-dose inhaled corticosteroids. On a population level, the pharmacokinetics of IND and GLY were comparable between patients with asthma and COPD.

RESUMEN

OBJECTIVE: Evidence of the efficacy of single-inhaler triple therapy in COPD patients inferred from RCTs has not been assessed in a real-world setting in Austria. In this non-interventional study (NIS) tolerability and effectiveness of extrafine beclometasone-dipropionate, formoterol-fumarate and glycopyrronium (Trimbow® 87/5/9 µg) was evaluated in COPD patients. METHODS: A prospective NIS was conducted over 52 weeks in 24 sites in Austria. Eligible COPD patients had an indication for treatment with single-inhaler BDP/FF/G. In this study tolerability, lung function, exacerbation rate, symptom scores and CAT scores were recorded. RESULTS: 265 patients with moderate to very severe airflow limitation (GOLD Grade 2-4: 96.2%) and persistent symptoms (GOLD B: 62.3%, GOLD D: 34%) according to the 2018 GOLD Report were included. After 52 weeks, a significant improvement was detected in lung function (FEV1, FEV1% predicted and FVC; p < 0.001) and symptoms (cough, sputum and shortness of breath; p < 0.001). A clinically relevant improvement in CAT score observed at 12 weeks persisted after 52 weeks in GOLD B and GOLD D patients (p < 0.001), paralleled by a significant reduction of moderate and severe exacerbations by 57.4% and 27.3%, respectively (p < 0.001). After 52 weeks, 93.7% of the patients continued the treatment. Of 21 adverse events reported 16 were non-serious, five were serious, none were deemed drug related. CONCLUSIONS: The present results support the tolerability and effectiveness of extrafine BDP/FF/G in COPD patients in a real-world setting, showing an improvement in lung function, symptom control and a significant reduction in exacerbations.

RESUMEN

BACKGROUND: A single-inhaler extrafine triple combination of beclometasone dipropionate (BDP), formoterol fumarate (FF) and glycopyrronium (G) has been developed for maintenance therapy of chronic obstructive pulmonary disease (COPD). This study evaluated the efficacy and safety of BDP/FF/G in patients in three eastern Asian areas: China, Republic of Korea and Taiwan. METHODS: TRIVERSYTI was a double-blind, randomised, active-controlled, parallel-group study in patients with COPD, post-bronchodilator forced expiratory volume in 1 s (FEV1) < 50% predicted, ≥ 1 exacerbation in the previous 12 months, and receiving inhaled maintenance medication. Patients received either extrafine BDP/FF/G 100/6/10 µg via pressurised metered-dose inhaler, or non-extrafine budesonide/formoterol (BUD/FF) 160/4.5 µg via dry-powder inhaler, both administered as two puffs twice-daily for 24 weeks. The co-primary objectives (analysed in the overall population) were to demonstrate superiority of BDP/FF/G over BUD/FF for change from baseline in pre-dose morning and 2-h post-dose FEV1 at Week 24 (these were analysed as key secondary objectives in the China subgroup). The rate of moderate/severe COPD exacerbations was a secondary endpoint. RESULTS: Of 708 patients randomised, 88.8% completed. BDP/FF/G was superior to BUD/FF for pre-dose and 2-h post-dose FEV1 at Week 24 [adjusted mean differences 62 (95% CI 38, 85) mL and 113 (87, 140) mL; both p < 0.001]. The annualised moderate/severe exacerbation rate was 43% lower with BDP/FF/G [rate ratio 0.57 (95% CI 0.42, 0.77); p < 0.001]. Adverse events were reported by 61.1% and 67.0% patients with BDP/FF/G and BUD/FF. Results were similar in the China subgroup. CONCLUSIONS: In patients with COPD, FEV1 < 50% and an exacerbation history despite maintenance therapy, treatment with extrafine BDP/FF/G improved bronchodilation, and was more effective at preventing moderate/severe COPD exacerbations than BUD/FF.

RESUMEN

OBJECTIVE: To evaluate cardiovascular safety of two new inhaled fixed-dose combinations for treatment of asthma: (i) the inhaled corticosteroid/long-acting beta2-agonist (ICS/LABA) mometasone furoate/indacaterol acetate (MF/IND), (ii) the ICS/LABA/long-acting muscarinic antagonist (LAMA) MF/IND/glycopyrronium bromide (GLY). METHODS: Patient-level data were pooled from four randomized trials, including 52-week studies PALLADIUM (n = 2216) and IRIDIUM (n = 3092), 24-week study ARGON (n = 1426), and 12-week study QUARTZ (n = 802). Cardio-/cerebrovascular (CCV) event frequencies were examined in the following comparisons: (1) LABA effect: pooled-dose MF/IND vs. pooled-dose MF; (2) LAMA effect: pooled-dose MF/IND/GLY vs. pooled-dose MF/IND; (3) ICS-dose effects: (a) high-dose MF/IND vs. medium-dose MF/IND, (b) high-dose MF/IND/GLY vs. medium-dose MF/IND/GLY; (4) intra-class effects: (a) high-dose MF/IND vs. Fluticasone/Salmeterol (F/S), (b) high-dose MF/IND/GLY vs. F/S + Tiotropium (TIO). Risk estimates (percentage of patients with ≥1 CCV event) and risk differences (RDs) with 95% confidence intervals (CIs) were calculated for each comparison. RESULTS: The frequency of CCV events was low, without notable differences between comparison groups. Risk estimates and corresponding RDs (95% CIs) were as follows: (1) pooled-dose MF/IND = 2.35%, pooled-dose MF = 2.18%, RD = 0.17% (-1.00%, 1.34%); (2) pooled-dose MF/IND/GLY = 3.65%, pooled-dose MF/IND = 3.77%, RD = -0.12% (-1.63%, 1.39%); (3a) high-dose MF/IND = 3.69%, medium-dose MF/IND = 3.35%, RD = 0.34% (-1.25%, 1.94%); (3b) high-dose MF/IND/GLY = 2.84%, medium-dose MF/IND/GLY = 2.02%, RD = 0.82% (-0.49%, 2.13%); (4a) high-dose MF/IND = 3.69%, F/S = 2.82%, RD = 0.87% (-0.66%, 2.40%); (4b) high-dose MF/IND/GLY = 1.26%, F/S + TIO = 1.05%, RD = 0.21% (-1.26%, 1.68%). CONCLUSIONS: There was no evidence of increased cardiovascular risk attributable to the addition of IND to MF or addition of GLY to MF/IND. Similarly, no evidence of increased cardiovascular risk was observed with an increase in the ICS-dose or relative to F/S ± TIO.

RESUMEN

Introduction: Sugammadex has been shown to be associated with prolongation of prothrombin time and activated partial thromboplastin time. However, it is not known whether it could be associated with enhancing postoperative hypocoagulation. The objective of this study was to analyze the effect of 4 mg/kg of sugammadex on thromboelastography (TEG) parameters in surgical patients. Methods: After Institutional Review Board approval, a prospective double-blinded randomized controlled study was conducted between September 2016 and April 2017. Sixty adult patients scheduled for laparoscopic abdominal surgery were randomly allocated to receive either sugammadex 4 mg/kg (sugammadex group) or pyridostigmine 0.15 mg/kg in combination with glycopyrrolate 0.4 mg (control group) to reverse rocuronium-induced neuromuscular blockade at the completion of surgery. Blood samples were collected three time points; After the final suture of surgery (baseline) (T1), and at 10 min (T2) and 1 h (T3) after administration of the study drug. Whole blood was analyzed by TEG using TEG 5000 (Hemonetics Corp, Braintree, MA, USA). The primary endpoints were comparison of coagulation time (K, time to 20 mm clot amplitude), R (reaction time), alpha angle, and maximal amplitude (MA) between two groups. Results: Coagulation time was significantly prolonged in sugammadex group after 10 min of the study drug administration compared to control group (mean value 1.3 ± 0.4 vs. 1.5 ± 0.4, P = 0.03). However, R, alpha angle and MA value were not different between two groups. Conclusions: Sugammadex 4 mg/kg showed an increase in coagulation time in surgical patients. Physician should aware the potential enhancement of hypocoagulation by sugammadex in the setting of high risk of postoperative bleeding.

RESUMEN

We describe a case of a young female who presented to the emergency department with 4 days of progressive myopia, dry mouth, anhidrosis and urinary hesitancy due to overuse of a new topical anticholinergic wipes, glycopyrronium tosylate (GT). In the United States medication misuse accounts for nearly 10% of pediatric emergency visits with 65% of these visits considered to be preventable [1]. Being familiar with new medications and their side effect profiles can prevent unnecessary or harmful interventions.

RESUMEN

BACKGROUND: A once-daily (o.d.) fixed-dose combination of indacaterol acetate (IND), glycopyrronium bromide (GLY), and mometasone furoate (MF) delivered via the Breezhaler® device (IND/GLY/MF) is being developed for treatment of asthma. This study compared steady-state pharmacokinetics of IND, GLY and MF between Japanese and Caucasian male subjects after multiple inhalations of IND/GLY/MF o.d. METHODS: This was a single-center, open-label, 2-treatment crossover study with a 21-day washout period. Japanese and Caucasian subjects received IND/GLY/MF 150/50/80 µg (inhaled corticosteroid [ICS] medium-dose) or 150/50/160 µg o.d. (ICS high-dose) for 14 days in each period. Pharmacokinetics were characterized up to 24 h post-dose on Days 1 and 14. RESULTS: In total, 16 Japanese (median age 31 years [range 20-40 years], mean weight 68.3 kg) and 17 Caucasian subjects (median age 27 years [range 21-43 years], mean weight 75.0 kg) were randomized. Geometric mean ratios (Japanese/Caucasian) [90% confidence interval (CI)] for Cmax for IND, GLY and MF at the high ICS dose on Day 14 were 1.31 [1.13, 1.51] 1.38 [1.13, 1.69] and 1.07 [0.969, 1.18], respectively. Geometric mean ratios (Japanese/Caucasian) [90% CI] for AUC0-24h on Day 14 for IND, GLY and MF at the high ICS dose were 1.17 [1.01, 1.35], 1.05 [0.920, 1.20] and 1.15 [1.05, 1.27] respectively. Similar trends were noted for all components for the medium ICS dose treatment. IND/GLY/MF was safe and well tolerated; no AEs suspected to be study drug-related were observed. CONCLUSION: Pharmacokinetics of IND, GLY and MF (high and medium dose) when delivered as a fixed-dose combination were comparable between Japanese and Caucasian subjects. The IND/GLY/MF combination at the administrated doses was safe and well tolerated in both ethnic groups. TRIAL REGISTRATION: Japan Registry of Clinical Trial: jRCT2031200227, retrospectively registered on 04, December, 2020.

RESUMEN

BACKGROUND: Previous studies have shown seasonal variation in asthma exacerbations, peaking over the winter months. A single-inhaler triple therapy containing extrafine formulations of the inhaled corticosteroid (ICS) beclomethasone dipropionate (BDP), long-acting ß2-agonist formoterol fumarate (FF), and long-acting muscarinic antagonist glycopyrronium (G) is in development for asthma. OBJECTIVE: We sought to evaluate whether calendar season impacted the relative effect of BDP/FF/G versus BDP/FF on moderate and severe asthma exacerbations. METHODS: TRIMARAN and TRIGGER were double-blind 52-week studies comparing BDP/FF/G with BDP/FF (TRIMARAN medium-dose ICS; TRIGGER high-dose) in adults with uncontrolled asthma (Asthma Control Questionnaire-7 score ≥1.5), prebronchodilator FEV1 less than 80% predicted, history of 1 or more asthma exacerbation, who had been receiving ICS/long-acting ß2-agonist for at least 4 weeks before entry. Moderate and severe asthma exacerbations were captured throughout each study. In these post hoc analyses, the annual moderate and severe exacerbation rate was calculated for each month, with rate ratios determined from events grouped by season. RESULTS: In patients who received BDP/FF alone, there was a marked seasonal effect on the occurrence of asthma exacerbations, with the rate highest in the winter months. However, the addition of the long-acting muscarinic antagonist component to BDP/FF reduced this seasonal variation, especially during the winter, such that the relative effect of BDP/FF/G versus BDP/FF was greatest in the winter (significant 20.3% reduction [P = .0008]). Reductions in the other seasons ranged between 8.6% and 12.0%. CONCLUSIONS: These post hoc analyses indicate that inhaled triple therapy with extrafine BDP/FF/G reduces seasonal peaks in moderate and severe exacerbations, and confirm the overall utility of adding long-acting muscarinic antagonist to ICS/long-acting ß2-agonist in the management of asthma.

RESUMEN

BACKGROUND: PINNACLE-4 evaluated the efficacy and safety of the long-acting muscarinic antagonist/long-acting ß2-agonist fixed-dose combination glycopyrrolate/formoterol fumarate metered dose inhaler (GFF MDI) in patients from Asia, Europe, and the USA with moderate-to-very severe chronic obstructive pulmonary disease (COPD). This pre-specified analysis included Japanese patients in PINNACLE-4. METHODS: In this double-blind randomized study (NCT02343458), patients received GFF MDI (18/9.6 µg), glycopyrrolate (GP) MDI (18 µg), formoterol fumarate (FF) MDI (9.6 µg), or placebo MDI twice daily for 24 weeks. The primary endpoint was change from baseline in morning pre-dose trough forced expiratory volume in 1 s (FEV1) over Weeks 12-24. Secondary lung function endpoints, patient-reported outcomes, and safety were assessed. The Japanese subpopulation (n = 150) analyses were exploratory. RESULTS: GFF MDI improved change from baseline in morning pre-dose trough FEV1 over Weeks 12-24 versus GP MDI, FF MDI, and placebo MDI (least squares mean [LSM] differences [95% confidence interval]: 69 [8-131], 60 [-1 to 121], and 275 [180-370] mL, respectively). GFF MDI numerically improved Transition Dyspnea Index focal score and change from baseline in St George's Respiratory Questionnaire total score versus placebo MDI (LSM differences 0.19 and -3.78, respectively). Treatment-related adverse events occurred in ≤4.5% of patients in any treatment group. CONCLUSIONS: GFF MDI improved lung function versus monocomponents and placebo MDI in the Japan subpopulation of PINNACLE-4. The efficacy and safety results were generally consistent with those of the global study population, supporting the use of GFF MDI in Japanese patients with moderate-to-very severe COPD.

RESUMEN

BACKGROUND: The effects of triple therapy on gas trapping in COPD are not fully understood. We evaluated the effects of the long acting bronchodilator components of the extrafine single inhaler triple therapy beclometasone dipropionate/formoterol/glycopyrronium (BDP/F/G) pMDI on gas trapping. METHODS: This open-label, randomised, single centre, 2-way cross-over study recruited 23 COPD patients taking inhaled corticosteroid combination treatments and with residual volume (RV) > 120% predicted at screening. Inhaled BDP was taken during run-in and washout periods. Baseline lung function (spirometry, lung volumes, oscillometry) was measured over 12 h prior to randomisation to BDP/F/G or BDP/F for 5 days followed by washout and crossover. Lung function was measured prior to dosing on day 1 and for 12 h post-dose on day 5. RESULTS: Co-primary endpoint analysis: BDP/F/G had a greater effect than BDP/F on FEV1 area under the curve over 12 h (AUC0-12) (mean difference 104 mls, p = 0.0071) and RV AUC0-12 (mean difference - 163 mls, p = 0.0028). Oscillometry measurements showed a greater effect of BDP/F/G on the difference between resistance at 5 and 20 Hz (R5-R20) AUC0-12, which measures small airway resistance (mean difference - 0.045 kPa/L/s, p = 0.0002). Comparison of BDP/F with the baseline measurements (BDP alone) showed that F increased FEV1 AUC0-12 (mean difference 227 mls) and improved RV AUC0-12 (mean difference - 558 mls) and R5-R20 AUC0-12 (mean difference - 0.117 kPa/L/s), all p < 0.0001. CONCLUSIONS: In COPD patients with hyperinflation, the G and F components of extrafine BDP/F/G improved FEV1, RV and small airway function. These long acting bronchodilators target small airway function, thereby improving gas trapping and airflow. Trial registration The study was retrospectively registered at ClinicalTrials.gov on 15th February 2019 (No.: NCT03842904, https://clinicaltrials.gov/ct2/show/NCT03842904 ).

RESUMEN

BACKGROUND: Hyperhidrosis is a condition characterized by excessive sweating beyond what is required for normal thermal regulation. It can involve multiple body areas including the axillae, palms, soles, or craniofacial regions. Glycopyrronium tosylate (GT) is a topical anticholinergic approved by the FDA (2018) for treatment of primary axillary hyperhidrosis in patients 9 years and older. OBJECTIVE: Gain insight into variables (anatomical sites, occlusion, exposure time) affecting GT delivery into human skin. METHODS: Human skin from different anatomical regions (palmar, plantar, axillary, and abdominal skin) was mounted into flow-through diffusion cells (MedFlux-HT®). GT solution (2.4%) was applied at 10 mg/cm2 and the receiving fluid was collected every 2 hours, for 24 hours. GT penetration was determined using LC/MS/MS. The effect of occlusion was assessed by covering the skin with either parafilm or saran wrap, and the effect of exposure time was assessed by incubating the skin for 5, 15, or 60 minutes before washing off the GT from the surface. RESULTS: GT delivery through palmar and plantar skin was up to 40-fold lower compared to delivery through axillary or abdominal skin. Occlusion increased GT delivery up to 10-fold. Reducing exposure time from 24 hours to either 5, 15, or 60 minutes, decreased GT flux by 90%. However, occlusion during these varied exposure times was able to restore GT delivery to levels found in the 24-hour exposed, non-occluded control group. CONCLUSION: These in vitro skin penetration studies showed that skin thickness, exposure time, and occlusion substantially influenced GT delivery, potentially impacting clinical trial design.
