Glycopyrronium 320 µg/mL in children and adolescents with severe sialorrhoea and neurodisabilities: A randomized, double-blind, placebo-controlled trial.

AIM: To investigate the efficacy, safety, and impact on quality of life (QoL) of an oral formulation of 320 µg/mL glycopyrronium designed for children. METHOD: A double-blind, placebo-controlled SALIVA (Sialanar plus orAl rehabiLitation against placebo plus oral rehabilitation for chIldren and adolescents with seVere sialorrhoeA and neurodisabilities) trial was conducted. Children (3-17 years) with neurodisabilities and severe sialorrhoea (modified Teachers Drooling Scale ≥6) were randomized to 320 µg/mL glycopyrronium or placebo, in addition to non-pharmacological standard care. RESULTS: Of 87 participants, 44 were aged 10 years or under and 43 had cerebral palsy. The primary endpoint, change in total Drooling Impact Scale (DIS) score from baseline to day 84, was significantly greater (improved) with 320 µg/mL glycopyrronium versus placebo (median [quartile 1, quartile 3] -29.5 [-44.5, 0] vs -1 [-16, 5]; p < 0.001), an effect also observed at day 28 (median - 25 vs -2; p < 0.01). Significant reduction in bibs/clothes used per day was seen with glycopyrronium versus placebo at day 84 (median - 2 vs 0; p < 0.01). Glycopyrronium significantly improved DIS items 9 and 10 related to the extent that drooling affects the child's and family's life (p ≤ 0.03). Adverse events were reported by 77.3% and 69.8% of children with glycopyrronium and placebo respectively; the most common treatment-related adverse event was constipation (20.5% and 16.3%). INTERPRETATION: The formulation of 320 µg/mL glycopyrronium significantly improved drooling and reduced its impact on QoL, with good tolerability in children with neurodisabilities. WHAT THIS PAPER ADDS: The formulation of 320 µg/mL glycopyrronium significantly improved Drooling Impact Scale score versus placebo at day 84. The formulation reduced the impact of drooling on the child's and family's quality of life. There were no safety or tolerability concerns with this specific formulation.

Can single-inhaler Beclometasone Dipropionate/Formoterol Fumarate/Glycopyrronium therapy postpone or save biologics for severe asthma?

Inhaled corticosteroids, along with beta2-agonists and anti-muscarinics, represent the cornerstone of asthma treatment. Although the advent of monoclonal antibodies has dramatically changed severe asthma management, there are still patients ineligible or with poor response to biologics. Moreover, high costs associated with monoclonal antibodies prescription are still an open issue, leading clinicians to carefully assess cost-benefit ratio before their administration. From this perspective, the use of single-inhaler Beclometasone Dipropionate/Formoterol Fumarate/Glycopyrronium in patients with severe asthma could not only improve their clinical and functional performance, but also postpone biologic prescription, with positive repercussions on healthcare costs.

LABA/LAMA versus LABA/ICS fixed-dose combinations in the prevention of COPD exacerbations: a modeling analysis of literature aggregate data.

OBJECTIVES: This study aimed to quantitatively compare the efficacy and safety of long-acting ß2-agonist (LABA)/long-acting muscarinic antagonist (LAMA) and LABA/inhaled corticosteroid (ICS) fixed-dose combinations (FDCs) in preventing moderate or severe chronic obstructive pulmonary disease (COPD) exacerbations. METHODS: A literature search was performed using public databases. The time course characteristics of the probability of a moderate or severe exacerbation in stable COPD patients treated with LABA/LAMA and LABA/ICS FDCs were described by the parametric survival function. A random-effects model in a single-arm meta-analysis was used to analyze the incidence of serious adverse events (SAEs) and pneumonia. RESULTS: Twenty studies including 23,955 participants were included. The proportion of participants with a history of COPD exacerbation (%) in the previous year and the postbronchodilator forced expiratory volume in the first second (FEV1) (%predicted) were important factors affecting drug efficacy. After adjusting the above factors to median levels of 100% and 45.5%, respectively, the moderate or severe exacerbation rates at 52 weeks for olodaterol/tiotropium, formoterol/budesonide, indacaterol/glycopyrronium, formoterol/glycopyrronium, vilanterol/fluticasone, salmeterol/fluticasone, and vilanterol/umeclidinium were 38.3%, 41.0%, 42.6%, 47.0%, 47.5%, 47.9%, and 53.0%, respectively. In terms of safety, significant differences were observed among drugs containing different LABA/LAMA FDCs. CONCLUSIONS: This study showed that not all LABA/LAMA FDCs were superior to LABA/ICS FDCs in safety and in preventing moderate or severe exacerbations in patients with stable COPD, providing important quantitative information for COPD-related guidelines.

Long-term safety of once-daily indacaterol acetate/glycopyrronium bromide/mometasone furoate high-dose, and indacaterol acetate/mometasone furoate high-dose, in Japanese patients with inadequately controlled asthma: Results from two open-label, 52-week studies.

INTRODUCTION: The 52-week long-term safety of once-daily indacaterol acetate/glycopyrronium bromide/mometasone furoate (IND/GLY/MF) high-dose (150/50/160 µg) and IND/MF high-dose (150/320 µg) was evaluated in two studies enrolling Japanese patients with inadequately controlled asthma. METHODS: Study 1 (IND/GLY/MF) and Study 2 (IND/MF) were 52-week, phase III, open-label, single-arm, multicenter studies conducted in Japanese adult patients with inadequately controlled asthma. The primary endpoint was incidence and severity of treatment-emergent adverse events (AEs) over 52-weeks. RESULTS: In Study 1, 94 patients received IND/GLY/MF high-dose and 84 (89.4%) patients completed the 52-week study treatment; in Study 2, 51 patients received IND/MF high-dose and 48 (94.1%) patients completed the 52-week study treatment. In Study 1, 68.1% and 6.4% of 94 patients reported ≥1 AE and ≥1 serious AE (SAE) respectively. In Study 2, 78.4% of 51 patients reported ≥1 AE; no patients reported SAEs. The most commonly reported AEs were asthma (exacerbation; 30.9% and 54.9%) and nasopharyngitis (18.1% and 29.4%) in Study 1 and Study 2, respectively. Severe AEs including asthma (exacerbation) were reported in 13.8% and 13.7% of patients in Study 1 and Study 2, respectively. In Study 1, 10 patients (10.6%) reported treatment-related AEs, of which dysphonia (9 patients [9.6%]) was the most commonly reported; no treatment-related AEs were reported in Study 2. In Study 1, one death (not study drug-related) was reported after study discontinuation (92 days after last dose of study medication). CONCLUSIONS: Once-daily IND/GLY/MF and IND/MF high-dose were well-tolerated in Japanese patients with inadequately controlled asthma. No unexpected safety findings were observed.Supplemental data for this article is available online at.

Effectiveness of the pharmacological treatments for sialorrhea in patients with Parkinson's disease: a systematic review and network meta-analysis.

OBJECTIVES: The present systematic review and network meta-analysis of randomized control trials (RCTs) aimed to establish whether there are evidence-based differences in the pharmacological agents used to manage sialorrhea in patients with Parkinson's disease (PD). MATERIAL AND METHODS: The authors searched the databases: MEDLINE via PubMed, EMBASE, Scopus, Web of Science, and Cochrane Library for clinical trials. Unpublished trials were searched on clinicaltrials.gov and the Brazilian Clinical Trials Registry. Means and standard deviations of changes in the salivary flow or drooling reported by participants due to the interventions were recorded. RESULTS: The authors analyzed 13 RCTs. Compared to the placebo, types A and B of the botulinum toxin effectively reduced the salivary flow and the severity or frequency of drooling. However, the network meta-analysis did not differentiate between the botulinum toxin types. Ipratropium bromide and glycopyrrolate did not differ from the placebo. Indirect evidence showed that ipratropium had similar results to those obtained with both types of botulinum toxin. The CINeMA approach estimated the quality of the evidence as very low for all comparisons. CONCLUSION: The best treatment for sialorrhea in patients with PD is not fully elucidated yet. Therefore, more well-conducted randomized clinical trials are required to increase the level of evidence. CLINICAL RELEVANCE: There needs to be more evidence defining the best intervention to treat sialorrhea in patients with PD. However, botulinum toxin types A and B seem to reduce sialorrhea in patients effectively.

Effect of neuromuscular reversal with neostigmine/glycopyrrolate versus sugammadex on postoperative ileus following colorectal surgery.

BACKGROUND: Postoperative ileus (POI) is a common complication following colorectal surgery and is mediated in part by the cholinergic anti-inflammatory pathway (CAIP). Neostigmine (acetylcholinesterase inhibitor), co-administered with glycopyrrolate, is frequently given for neuromuscular reversal before tracheal extubation and modulates the CAIP. An alternative reversal agent, sugammadex (selective rocuronium or vecuronium binder), acts independently from the CAIP. The aim of our study was to assess the impact of neuromuscular reversal agents used during anaesthesia on gastrointestinal recovery. METHODS: Three hundred thirty-five patients undergoing elective colorectal surgery at the Royal Adelaide Hospital between January 2019 and December 2021 were retrospectively included. The primary outcome was GI-2, a validated composite measure of time to diet tolerance and passage of stool. Demographics, 30-day complications and length of stay were collected. Univariate and multivariate analyses were performed. RESULTS: Two hundred twenty-four (66.9%) patients (129 [57.6%] males and 95 [42.4%] females, median age 64 [19-90] years) received neostigmine/glycopyrrolate and 111 (33.1%) received sugammadex (62 [55.9%] males and 49 [44.1%] females, median age 67 [18-94] years). Sugammadex patients achieved GI-2 sooner after surgery (median 3 (0-10) vs. 3 (0-12) days, p = 0.036), and reduced time to first stool (median 2 (0-10) vs. 3 (0-12) days, p = 0.035). Rates of POI, complications and length of stay were similar. On univariate analysis, POI was associated with smoking history, previous abdominal surgery, colostomy formation, increased opioid use and postoperative hypokalaemia (p < 0.05). POI was associated with increased complications, including anastomotic leak and prolonged hospital stay (p < 0.001). On multivariate analysis, neostigmine, bowel anastomoses and increased postoperative opioid use (p < 0.05) remained predictive of time to GI-2. CONCLUSIONS: Patients who received sugammadex had a reduced time to achieving first stool and GI-2. Neostigmine use, bowel anastomoses and postoperative opioid use were associated with delayed time to achieving GI-2.

Budesonide/glycopyrronium/formoterol fumarate triple therapy prevents pulmonary hypertension in a COPD mouse model via NFκB inactivation.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a health problem that results in death, commonly due to the development of pulmonary hypertension (PH). Here, by utilizing a mouse model of intratracheal elastase-induced emphysema that presents three different phases of COPD, we sought to observe whether budesonide/glycopyrronium/formoterol fumarate (BGF) triple therapy could prevent COPD-PH in addition to ameliorating COPD progression. METHODS: We utilized intratracheal elastase-induced emphysema mouse model and performed experiments in three phases illustrating COPD progression: inflammatory (1 day post-elastase), emphysema (3 weeks post-elastase) and PH (4 weeks post-elastase), while treatments of BGF and controls (vehicle, one-drug, and two-drug combinations) were started in prior to elastase instillation (inflammatory phase), at day 7 (emphysema), or at day 14 (PH phase). Phenotype analyses were performed in each phase. In vitro, A549 cells or isolated mouse lung endothelial cells (MLEC) were treated with TNFα with/without BGF treatment to analyze NFκB signaling and cytokine expression changes. RESULTS: We observed significant reductions in the proinflammatory phenotype observed in the lungs and bronchoalveolar lavage fluid (BALF) 1 day after elastase administration in mice treated with BGF compared with that in mice administered elastase alone (BALF neutrophil percentage, p = 0.0011 for PBS/Vehicle vs. PBS/Elastase, p = 0.0161 for PBS/Elastase vs. BGF). In contrast, only BGF treatment significantly ameliorated the elastase-induced emphysematous lung structure and desaturation after three weeks of elastase instillation (mean linear intercept, p = 0.0156 for PBS/Vehicle vs. PBS/Elastase, p = 0.0274 for PBS/Elastase vs. BGF). Furthermore, BGF treatment prevented COPD-PH development, as shown by improvements in the hemodynamic and histological phenotypes four weeks after elastase treatment (right ventricular systolic pressure, p = 0.0062 for PBS/Vehicle vs. PBS/Elastase, p = 0.027 for PBS/Elastase vs. BGF). Molecularly, BGF acts by inhibiting NFκB-p65 phosphorylation and subsequently decreasing the mRNA expression of proinflammatory cytokines in both alveolar epithelial and pulmonary endothelial cells. CONCLUSION: Our results collectively showed that BGF treatment could prevent PH in addition to ameliorating COPD progression via the inhibition of inflammatory NFκB signaling.

Budesonide/Glycopyrrolate/Formoterol Fumarate Co-suspension Metered Dose Inhaler: A Triple Therapy for the Treatment of Chronic Obstructive Pulmonary Disease.

OBJECTIVE: To review current evidence on the use of a fixed-dose combination (FDC) of budesonide/glycopyrrolate/formoterol fumarate (BGFF) triple therapy delivered via metered dose inhaler (MDI) in patients with chronic obstructive pulmonary disease (COPD) and offer clinical practice insights. DATA SOURCES: We used PubMed to conduct the literature search from 1946 through June 30, 2021, using budesonide, glycopyrrolate or glycopyrronium, and formoterol. STUDY SELECTION AND EXTRACTION: We included clinical trials in patients with COPD along with pharmacokinetic or pharmacodynamic studies. DATA SYNTHESIS: In all, 19 citations were included. BGFF MDI reduces the risk of exacerbations regardless of exacerbation history compared with dual bronchodilators or inhaled corticosteroid/long-acting ß-agonist. Rescue inhaler use decreased, and patient-reported outcomes of symptoms and well-being improved with triple therapy. Mortality was decreased with the higher-dose BGFF MDI in comparison to dual bronchodilator therapy. Dysphonia and candidiasis were more common with BGFF MDI compared with dual bronchodilators, as was pneumonia. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE: BGFF MDI is the second FDC triple therapy approved for COPD treatment. BGFF MDI improves important patient outcomes in COPD, including exacerbation risk. The unique co-suspension technology allows delivery of 3 active ingredients in 1 inhaler, a potential benefit to overcome adherence and technique-related barriers. These benefits must be gently weighed against the increased risk of pneumonia. CONCLUSION: The findings from phase 3 trials support the efficacy and safety of triple therapy in COPD. Future studies are needed to confirm potential mortality benefit and the role of triple therapy in patients without an exacerbation history.

Reduced All-Cause Mortality in the ETHOS Trial of Budesonide/Glycopyrrolate/Formoterol for Chronic Obstructive Pulmonary Disease. A Randomized, Double-Blind, Multicenter, Parallel-Group Study.

Rationale: In the phase III, 52-week ETHOS (Efficacy and Safety of Triple Therapy in Obstructive Lung Disease) trial in chronic obstructive pulmonary disease (COPD) (NCT02465567), triple therapy with budesonide/glycopyrrolate/formoterol fumarate (BGF) significantly reduced all-cause mortality compared with glycopyrrolate/formoterol fumarate (GFF). However, 384 of 8,509 patients were missing vital status at Week 52 in the original analyses.Objectives: To assess the robustness of the ETHOS mortality findings after additional data retrieval for patients missing Week 52 vital status in the original analyses.Methods: Patients with moderate to very severe COPD and prior history of exacerbation received twice-daily dosing with 320/18/9.6 µg of BGF (BGF 320), 160/18/9.6 µg of BGF (BGF 160), 18/9.6 µg of GFF, or 320/9.6 µg of budesonide/formoterol fumarate (BFF) (all delivered via a single metered-dose Aerosphere inhaler). Time to death (all-cause) was a prespecified secondary endpoint.Measurements and Main Results: In the final retrieved dataset, which included Week 52 vital status for 99.6% of the intent-to-treat population, risk of death with BGF 320 was significantly lower than GFF (hazard ratio, 0.51; 95% confidence interval, 0.33-0.80; unadjusted P = 0.0035). There were no significant differences in mortality when comparing BGF 320 with BFF (hazard ratio, 0.72; 95% confidence interval, 0.44-1.16; P = 0.1721), nor were significant differences observed when comparing BGF 160 against either dual comparator. Results were similar when the first 30, 60, or 90 days of treatment were excluded from the analysis. Deaths from cardiovascular causes occurred in 0.5%, 0.8%, 1.4%, and 0.5% of patients in the BGF 320, BGF 160, GFF, and BFF groups, respectively.Conclusions: Using final retrieved vital status data, triple therapy with BGF 320 reduced the risk of death compared with GFF, but was not shown to significantly reduce the risk of death compared with BFF, in patients with COPD. Triple therapy containing a lower dose of inhaled corticosteroid (BGF 160) was not shown to significantly reduce the risk of death compared with the dual therapy comparators.

Effect of glycopyrrolate on vasopressor requirements for non-elective cesarean section under spinal anesthesia: a randomized, double-blind, placebo-controlled trial.

BACKGROUND: The study aimed to investigate whether prophylactic use of glycopyrrolate decreases the vasopressor requirements to prevent hypotension following spinal anesthesia during non-elective cesarean section. METHOD: In this double-blind randomized clinical trial, 258 patients undergoing non-elective cesarean section were randomly assigned (1:1) to receive intravenous 0.2 mg glycopyrrolate or normal saline (placebo) before spinal anesthesia. The primary outcome was phenylephrine equivalent needed intraoperatively. Secondary outcomes included incidences of maternal hypotension, reactive hypertension, bradycardia, need for atropine, tachycardia, intraoperative nausea/vomiting, shivering, pruritus, dry mouth, dizziness; neonatal APGAR score at 1 min and 5 min, neonatal resuscitation needed, NICU admission and neonatal death. RESULTS: Three patients withdrew from the study due to failed spinal anesthesia. 128 patients in the glycopyrrolate group and 127 patients in the placebo group were analyzed. The mean phenylephrine equivalent needed was 1108.96 µg in the glycopyrrolate group and 1103.64 µg in the placebo group (mean difference, 5.32 µg [95% CI - 67.97 to 78.62]; P = 0.88). Hypotension occurred in 38 patients (30%) in the glycopyrrolate group as compared with 49 patients (39%) in the placebo group (P = 0.13). Tachycardia was reported in 70% of the participants in the glycopyrrolate group and 57% of those in the placebo group (P = 0.04). No statistically significant difference was noted in hypotensive episodes > 1, reactive hypertension, bradycardia, need for atropine, nausea, vomiting, shivering, and dry mouth between the two groups. Neonatal outcomes were similar in the two groups. CONCLUSION: Prophylactic use of glycopyrrolate does not decrease the requirements of vasopressor to prevent hypotension in non-elective cesarean section under spinal anesthesia.

Sugammadex reversal of muscle relaxant blockade provided less Post-Anesthesia Care Unit adverse effects than neostigmine/glycopyrrolate.

Sugammadex is a direct reversal agent of aminosteroid muscle relaxants, particularly rocuronium, with promptly and completely reverse of deep neuromuscular block (NMB), which allows better surgical conditions. Sugammadex exhibits advantages over indirect reversal agent acetylcholinesterase inhibitor neostigmine with less adverse effects. In this retrospective review, we compared the incidence of postoperative vomiting (POV), postoperative urinary retention (POUR), and hemodynamic changes between sugammadex and neostigmine/glycopyrrolate in reversal of muscular blockade. Sugammadex showed superior in all three aspects. The heart rate was 7.253 lower (P < 0.0001) and mean arterial pressure was 5.213 lower (P < 0.0001) in sugammadex group. The POV of neostigmine/glycopyrrolate group was 3.16 times more than sugammadex group (OR = 3.16, p < 0.0001), and POUR of neostigmine/glycopyrrolate group was 4.291 times more than sugammadex group (OR = 4.291, p < 0.0001). Sugammadex showed better hemodynamic stability, and lower incidence of POV and POUR than neostigmine/glycopyrrolate.

[Fixed combination of budesonide, formoterol, glycopyrronium for the treatment of severe COPD : Trixeo Aerosphere®]. / Le médicament du mois. Combinaison fixe budésonide, formotérol, glycopyronium pour le traitement de la BPCO modérée à sévère : Trixeo Aerosphère®.

Here we present pharmacological and clinical properties of a new fixed triple inhaled combination including an inhaled corticoid, a long acting ?2 agonist and a long acting anticholinergic for the treatment of severe chronic obstructive pulmonary disease (COPD). Trixeo Aerosphere® is the name of this triple combination which contains 160 µg budesonide, 4,8 µg formoterol and 9 µg glycopyrronium delivered by a pMDI. As compared to a budesonide/formoterol combination, Trixeo Aerosphere® improves forced expiratory volume in the first second (FEV1). As compared to glycopyrronium/formoterol combination, Trixeo Aerosphere® reduces exacerbation rate, improved quality of life and most importantly reduces mortality with a benefit increasing with blood eosinophil count. Trixeo Aerosphere® 320/18/9.6 is delivered twice daily 2 inhalations and is indicated in moderate to severe COPD insufficiently controlled by LABA/LAMA (long-acting ?2-adrenergic receptor agonist/ long-acting ?2-muscarinic receptor agonist) or ICS/LABA (inhaled corticosteroid/long-acting ?2-adrenergic receptor agonist).

Nous présentons dans cet article les propriétés pharmacologiques et les effets cliniques d'une nouvelle triple combinaison fixe inhalée comprenant un corticoïde inhalé, un ?2 mimétique à longue durée d'action et un anticholinergique à longue durée d'action, destinée au traitement de la bronchopneumopathie chronique obstructive (BPCO) sévère. Cette combinaison qui porte le nom de Trixeo Aerosphere® regroupe, dans le même dispositif, 160 µg de budésonide, 4,8 µg de formotérol et 18 µg de glycopyrronium. Par rapport à une combinaison budésonide/formotérol, le Trixeo Aerosphere® améliore la valeur du volume expiratoire maximum par seconde (VEMS). Par rapport à une combinaison formotérol/glycopyrronium, le Trixeo Aerosphere® réduit la fréquence des exacerbations et réduit la mortalité avec un bénéfice qui augmente avec le taux des éosinophiles circulants. Le Trixeo Aerosphere®, à la dose de 2X2 bouffées/24h, est indiqué dans le traitement des patients BPCO modérés à sévères insuffisamment contrôlés par une bithérapie LABA/LAMA (long-acting ?2-adrenergic receptor agonist/ long-acting ?2-muscarinic receptor agonist) ou ICS/LABA (inhaled corticosteroid/long-acting ?2-adrenergic receptor agonist).

Effects of indacaterol on the LPS-evoked changes in fluid secretion rate and pH in swine tracheal membrane.

An acquired dysregulation of airway secretion is likely involved in the pathophysiology of chronic bronchitis and chronic obstructive pulmonary disease (COPD). Nowadays, it is widely known that several kinds of long-acting bronchodilators reduce the frequency of COPD exacerbations. However, limited data are available concerning the complementary additive effects on airflow obstruction. Using an optical method and a selective pH indicator, we succeeded in evaluating the gland secretion rate and the pH in swine tracheal membrane. A physiologically relevant concentration of acetylcholine (ACh) 100 nM induced a gradual increase in the amount of gland secretion. Lipopolysaccharides (LPS) accelerated the ACh-induced secretory responses up to around threefold and lowered the pH level significantly. Long-acting ß2-agonists (LABAs) including indacaterol (IND), formoterol, and salmeterol restored the LPS-induced changes in both the hypersecretion and acidification. The subsequent addition of the long-acting muscarine antagonist, glycopyrronium, further increased the pH values. Two different inhibitors for cystic fibrosis transmembrane conductance regulator (CFTR), NPPB and CFTRinh172, abolished the IND-mediated pH normalization in the presence of both ACh and ACh + LPS. Both immunofluorescence staining and western blotting analysis revealed that LPS downregulated the abundant expression of CFTR protein. However, IND did not restore the LPS-induced decrease in CFTR expression on Calu-3 cells. These findings suggest that the activation of cAMP-dependent HCO3- secretion through CFTR would be partly involved in the IND-mediated pH normalization in gland secretion and may be suitable for the maintenance of airway defense against exacerbating factors including LPS.

Ceiling effect of beclomethasone/formoterol/glycopyrronium triple fixed-dose combination in COPD: A translational bench-to-bedside study.

BACKGROUND: Currently, data on the possible synergy of adding a LAMA to ICS/LABA combination are missing and no studies assessed whether triple therapy may induce ceiling bronchodilator effect. A translational study was performed to investigate the interaction between glycopyrronium bromide (GB) and beclomethasone dipropionate (BDP)/formoterol fumarate (FF) combination in human isolated airways and the effect on FEV1 and small airway resistance of BDP/FF/GB in COPD. METHODS: The interaction of adding GB to BDP/FF combination was tested in vitro in medium and small airways via Bliss, Loewe, and Highest Single Agent models. The peak and trough effect on FEV1 and R5-R19 of salbutamol on top of BDP/FF/GB 100/6/12.5 µg FDC via extrafine formulation was investigated in severe COPD patients after two weeks of treatment. RESULTS: GB plus BDP/FF elicited significant synergistic bronchorelaxation in medium and small isolated airways (overall maximal effect: +32% vs. additive effect). No significant (P > 0.05) improvement in R5-R19 was detected when salbutamol was administered on top of BDP/FF/GB 100/6/12.5 µg FDC (peak -0.12 ± 0.22 cmH2O/L/s, trough -0.23 ± 0.25 cmH2O/L/s). Salbutamol significantly (P < 0.01) increased FEV1 when administered on top of triple FDC (peak +145 ± 119 ml, trough +221 ± 111 ml). CONCLUSION: The synergistic interaction detected in vitro when adding GB to BDP/FF combination may lead to ceiling bronchorelaxation of small airways in vivo, an effect that may improve hyperinflation in subjects with small airway disease and, thus, explain the substantial clinical benefits of triple combination therapy administered via extrafine formulation in severe COPD patients.

Dose bridging data for mometasone furoate in once-daily fixed-dose inhaled combinations of mometasone furoate/indacaterol and mometasone furoate/ indacaterol/glycopyrronium in patients with asthma.

Once-daily (o.d.) fixed-dose combinations of mometasone furoate/indacaterol acetate (MF/IND) and mometasone furoate/indacaterol acetate/glycopyrronium bromide (MF/IND/GLY), both delivered via the Breezhaler® device, are approved for the maintenance treatment of asthma. Across these fixed-dose combinations, while the doses of bronchodilators remain the same, the nominal doses of mometasone furoate in micrograms differ. This article presents the steps followed in bridging the mometasone furoate doses at the corresponding dose strengths in the mometasone furoate formulation delivered via the Twisthaler® and mometasone furoate/indacaterol acetate and mometasone furoate/indacaterol acetate/glycopyrronium bromide formulations delivered via the Breezhaler®. These were: (i) bridging the mometasone furoate doses in the Twisthaler® (previously approved) to mometasone furoate doses in the Breezhaler®; (ii) bridging the mometasone furoate doses in the Breezhaler® to mometasone furoate/indacaterol acetate and mometasone furoate/indacaterol acetate/glycopyrronium bromide formulation. Following this stepwise approach, it was determined that mometasone furoate 80 µg o.d. (medium-dose strength) and 160 µg o.d. (high-dose strength) in mometasone furoate/indacaterol acetate/glycopyrronium bromide formulation provided comparable inhaled corticosteroid efficacy to mometasone furoate 160 µg o.d. (medium-dose strength) and 320 µg o.d. (high-dose strength) in the mometasone furoate/indacaterol acetate formulation, respectively. These doses were used in the PLATINUM Phase III clinical program that investigated the efficacy and safety of mometasone furoate/indacaterol acetate and mometasone furoate/indacaterol acetate/glycopyrronium bromide combinations in patients with asthma.

Which LABA/LAMA should be chosen in COPD patients in real life?

BACKGROUND: Given COPD heterogeneity, we do not know if some LABA/LAMAs are more suitable for some COPD phenotypes. This real-life database study aimed to evaluate retrospectively the 4 LABA/LAMA effectiveness and highlight possible specificities that could better guide us in choosing the right LABA/LAMA to be used. METHODS: We searched for subjects (1,779) adherent to umeclidinium/vilanterol (UM/VI), indacaterol/glycopyrronium (IND/GLY), aclidinium/formoterol (ACLI/FOR) and tiotropium/olodaterol (TIO/OLO) treatments in our prescribing/dispensing database. Prescriptions for systemic corticosteroids (SC), antibiotics and salbutamol during one year of LABA/LAMA treatment were analyzed. RESULTS: A better adherence was found in individuals taking IND/GLY (10.42 ± 1.86 packages/year) compared with UM/VI (10.09 ± 1.9; p = 0.008), ACLI/FOR (9.8 ± 1.8; p = 0.001) and TIO/OLO (10.1 ± 2.1; p = 0.047). The number of patients that were prescribed at least one package of SC/year and their package numbers/year were similar in males/females, across age groups and in "non-frequent exacerbators" with the 4 LABA/LAMAs. More SC were taken by frequent exacerbators, whereas fewer SC/antibiotic packages were prescribed to subjects aged >80 years with all treatments. In patients treated with ACLI/FOR or TIO/OLO, lower risks to having antibiotic prescriptions were observed when UM/VI (0.698[0.516-0.945] and 0.696[0.491-0.985; p = 0.020 and p = 0.041) and IND/GLY (0.597[0.445-0.802] and 0.595[0.423-0.836]; p = 0.001 and p = 0.003) were considered as landmarks. Lower risks for salbutamol prescriptions were detected with UM/VI (0.678[0.480-0.958]; p = 0.027) and TIO/OLO (0.585[0.365-0.937]; p = 0.026) when ACLI/FOR was used as a reference. CONCLUSION: According to our retrospective database study, each LABA/LAMA could have a specific efficacy profile in COPD that might be considered for personalized therapy. However, head-to-head targeted trials aimed to assess the impact of different LABA/LAMAs on COPD are needed to confirm/disprove such results.

Efficacy and Safety of Inhaled Glycopyrronium Bromide in COPD: A Randomized, Parallel Group, Dose-Ranging Study (GLIMMER).

This Phase II, randomized, parallel group study was conducted as part of US regulatory requirements to identify the most appropriate dose of the long-acting muscarinic antagonist glycopyrronium bromide (GB) for use in a single-inhaler triple-therapy combination with the inhaled corticosteroid beclomethasone dipropionate plus the long-acting ß2-agonist formoterol fumarate. Eligible subjects were adults with COPD and post-bronchodilator forced expiratory volume in 1 s (FEV1) 40-80% predicted. Subjects were randomized to receive inhaled double-blind GB 6.25, 12.5, 25 or 50 µg or placebo, all twice daily (BID), or open-label tiotropium 18 µg once daily for six weeks. The primary objective was to evaluate the efficacy of GB versus placebo in terms of FEV1 area under the curve between 0 and 12 h at Week 6. Of 733 subjects randomized, 682 (93.0%) completed the study. For the primary endpoint, all GB doses were superior to placebo (p < 0.05), with a dose-response up to 25 µg BID, and 25 and 50 µg BID both superior to 6.25 µg BID (p < 0.05). Results for the secondary spirometry endpoints were consistent with the primary endpoint. Overall, the efficacy of GB 25 and 50 µg BID was broadly consistent with that of tiotropium. The incidence of adverse events, both overall and for the most common preferred terms, was low and similar in all treatment groups, including placebo (overall, 22.3-29.3%). Based on the totality of the efficacy and safety data, the optimal GB dose is 25 µg BID.

Single inhaler extrafine triple therapy in uncontrolled asthma (TRIMARAN and TRIGGER): two double-blind, parallel-group, randomised, controlled phase 3 trials.

BACKGROUND: To date, no studies have assessed the efficacy of single-inhaler triple therapy in asthma. Here we report on two studies that compared the single-inhaler extrafine combination of beclometasone dipropionate (BDP; inhaled corticosteroid), formoterol fumarate (FF; long-acting ß2 agonist), and glycopyrronium (G; long-acting muscarinic antagonist) with the combination of BDP with FF. METHODS: Two parallel-group, double-blind, randomised, active-controlled, phase 3 trials (Triple in Asthma With Uncontrolled Patients on Medium Strength of ICS + LABA [TRIMARAN] and Triple in Asthma High Strength Versus ICS/LABA HS and Tiotropium [TRIGGER]) recruited patients from 171 sites across 16 countries (TRIMARAN), and from 221 sites across 17 countries (TRIGGER). The sites were a mixture of secondary and tertiary care centres and specialised investigation units. Eligible patients were adults (aged 18-75 years) with uncontrolled asthma, a history of one or more exacerbations in the previous year, and previously treated with inhaled corticosteroid (TRIMARAN: medium dose; TRIGGER: high dose) plus a long-acting ß2 agonist. Enrolled patients were initially treated with BDP/FF (TRIMARAN: 100 µg BDP and 6 µg FF; TRIGGER: 200 µg BDP and 6 µg FF) for 2 weeks, then randomly assigned to treatment using an interactive response technology system with a balanced block randomisation scheme stratified by country. Patients, investigators, site staff, and sponsor staff were masked to BDP/FF/G and BDP/FF assignment. In TRIMARAN, patients were randomly assigned (1:1) to 52 weeks of BDP/FF/G (100 µg BDP, 6 µg FF, and 10 µg G) or BDP/FF (100 µg BDP and 6 µg FF), two inhalations twice daily. In TRIGGER, patients were randomly assigned (2:2:1) to 52 weeks of BDP/FF/G (200 µg BDP, 6 µg FF, and 10 µg G) or BDP/FF (200 BDP and 6 µg FF), both two inhalations twice daily, or open-label BDP/FF (200 µg BDP and 6 µg FF) two inhalations twice daily plus tiotropium 2·5 µg two inhalations once daily. Coprimary endpoints for both trials (BDP/FF/G vs BDP/FF) were pre-dose forced expiratory volume in 1 s (FEV1) at week 26 and rate of moderate and severe exacerbations over 52 weeks. Safety was assessed in all patients who received at least one dose of study treatment. These trials were registered with ClinicalTrials.gov, NCT02676076 (TRIMARAN), NCT02676089 (TRIGGER). FINDINGS: Between Feb 17, 2016, and May 17, 2018, 1155 patients in TRIMARAN were given BDP/FF/G (n=579) or BDP/FF (n=576). Between April 6, 2016, and May 28, 2018, 1437 patients in TRIGGER were given BDP/FF/G (n=573), BDP/FF (n=576), or BDP/FF plus tiotropium (n=288). Compared with the BDP/FF group, week 26 predose FEV1 improved in the BDP/FF/G group by 57 mL (95% CI 15-99; p=0·0080) in TRIMARAN and by 73 mL (26-120; p=0·0025) in TRIGGER, with reductions in the rate of moderate and severe exacerbations of 15% (rate ratio 0·85, 95% CI 0·73-0·99; p=0·033) in TRIMARAN and 12% (0·88, 0·75-1·03; p=0·11) in TRIGGER. Four patients had treatment-related serious adverse events, one in TRIMARAN in the BDP/FF/G group and three in TRIGGER-one in the BDP/FF/G and two in the BDP/FF group. Three patients in the BDP/FF/G group in TRIMARAN and two patients in TRIGGER-one in the BDP/FF/G group and one in the BDP/FF group-had adverse events leading to death. None of the deaths were considered as related to treatment. INTERPRETATION: In uncontrolled asthma, addition of a long-acting muscarinic antagonist to inhaled corticosteroid plus long-acting ß2-agonist therapy improves lung function and reduces exacerbations.

Ethnic pharmacokinetic comparison of budesonide/glycopyrrolate/formoterol fumarate metered dose inhaler (BGF MDI) between Asian and Western healthy subjects.

BACKGROUND: The Phase III KRONOS study (NCT02497001) found the fixed-dose combination triple therapy budesonide/glycopyrrolate/formoterol fumarate metered dose inhaler (BGF MDI) to be efficacious and well tolerated versus corresponding dual therapies in patients with moderate-to-very severe COPD from North America, China and Japan. However, pharmacokinetic (PK) studies of other drugs have shown that ethnic factors (e.g. genetic factors affecting drug metabolism) can affect the bioavailability of drugs which may impact upon efficacy and safety outcomes. METHODS: This was a post-hoc analysis of data from four randomised, double-blind Phase I studies of BGF MDI 320/18/9.6 µg and 160/18/9.6 µg in Chinese (NCT03075267), Japanese (NCT02197975) and Western (NCT01980615, NCT02189304) healthy subjects. PK properties (area under the plasma concentration-time curve 0-12 h post-dose [AUC0-12] and maximum plasma concentration, [Cmax]) were recorded following single and repeated dosing of BGF MDI 320/18/9.6 µg or 160/18/9.6 µg. Potential ethnic differences in the PK properties of budesonide, glycopyrrolate and formoterol in Chinese, Japanese and Western healthy subjects were derived by non-compartmental analysis, and ethnic insensitivity factors evaluated based on criteria from the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use, Guideline E5 Ethnic Factors in the Acceptability of Foreign Clinical Data. RESULTS: The analyses included data from 64 Chinese, 31 Japanese and 169 Western subjects. Overall, PK properties following single or repeated dosing of BGF MDI were similar across Chinese, Japanese and Western subjects. After single dosing at either dose level, AUC0-12 and Cmax for budesonide, glycopyrrolate and formoterol appeared generally similar for Asian (Chinese and Japanese) versus Western subjects, with most geometric least squares mean ratios within the range of 0.92-1.22. The exception was that Cmax for glycopyrrolate was slightly lower in Asian versus Western subjects (0.6-0.7). Of the 10 ethnic insensitivity factors evaluated, six were met for budesonide, nine for glycopyrrolate and nine for formoterol, suggesting that BGF MDI can be classified as an ethnically insensitive drug. CONCLUSIONS: Overall, these analyses suggest no appreciable ethnic differences in the PK of BGF MDI across Chinese, Japanese and Western healthy subjects.

Dual use of bronchodilators versus monotherapy, and its impact on pulmonary rehabilitation in COPD patients.

INTRODUCTION: Long-acting bronchodilators are the therapy with the best evidence for treating stable chronic obstructive pulmonary disease (COPD). Long-acting combinations of ß2 agonists and anticholinergics (LABA-LAMA) are recommended in advanced stages when monotherapy has not generated the desired effects. Pulmonary Rehabilitation (PR) is an effective non-pharmacological strategy. The aim of this study was to compare the results obtained in patients with COPD who received monotherapy versus dual bronchodilator therapy in terms of functional aerobic capacity, symptoms and quality of life. MATERIALS AND METHODS: Prospective non randomized intervention study; the patients were divided into two groups: in one group patients were treated with LAMA (Tiotropium Bromide, 5 µg every 24 h) and in the other group patients were treated with LABA + LAMA (Indacaterol/Glycopyrronium, 110/50 µg once a day). After receiving the concept of pulmonology, patients were intervened with 8 weeks of PR. The study was approved by the committee of the Clinica Neumológica del Pacifico in Cali and the Institución Universitaria Escuela Nacional del Deporte, Colombia. To determine the differences, t pair test for intragroup, and t-test was performed for intergroup analysis. For all tests, a p-value <0.05 was considered as statistically significant. RESULTS: 53 patients participated in this study, of which 20 were assigned to the LAMA group and 33 to the LAMA + LABA group. Patients in both groups presented changes in the distance of the 6MWT, in the VO2e, dyspnea and in all the SGRQ domains. Regarding the comparison between groups, there were found no differences in the variables at the beginning of the PR and significant differences (p < 0.05) at the end of the 8 week-period in favor of the LABA + LAMA group, in symptoms with the mMRC scale, functional aerobic capacity with the 6 min walking test and in health related quality of life specifically in the symptoms domain, where the dual therapy group obtained better results. CONCLUSION: The addition of LABA to the treatment with LAMA showed better response results compared with the monotherapy in patients with COPD who attended PR.
