NVA237 (glycopyrronium bromide) is a once-daily long-acting muscarinic antagonist (LAMA) in development for chronic obstructive pulmonary disease (COPD). The GLycopyrronium bromide in COPD airWays clinical Study 2 (GLOW2) evaluated the efficacy and safety of NVA237 in moderate-to-severe COPD over 52 weeks.Patients were randomised 2:1:1 to NVA237 50 μg, placebo or open-label tiotropium 18 μg for 52 weeks. Primary end-point was trough forced expiratory volume in 1 s (FEV1) at 12 weeks.1,066 patients were randomised, 810 completed the study. At week 12, trough FEV1 increased significantly by 97 mL with NVA237 (95% CI 64.6–130.2; p<0.001) and 83 mL with tiotropium (95% CI 45.6–121.4; p<0.001). Compared with placebo, NVA237 produced significant improvements in dyspnoea (Transition Dyspnoea Index at week 26; p=0.002) and health status (St George's Respiratory Questionnaire at week 52; p<0.001). NVA237 significantly reduced the risk of moderate-to-severe COPD exacerbations by 34% (p=0.001) and the use of rescue medication (p=0.039), versus placebo. NVA237-placebo and tiotropium-placebo differences were comparable for all outcomes. Safety profiles were similar across groups.NVA237 50 μg provided significant improvements in lung function, dyspnoea, health status, exacerbations and rescue medication use, versus placebo, and was comparable to tiotropium. NVA237 can potentially be an alternative choice of LAMA for COPD patients.
BackgroundNVA237 is a once-daily dry-powder formulation of the long-acting muscarinic antagonist glycopyrronium bromide in development for the treatment of chronic obstructive pulmonary disease (COPD). The glycopyrronium bromide in COPD airways clinical study 1 (GLOW1) evaluated the efficacy, safety and tolerability of NVA237 in patients with moderate-to-severe COPD.MethodsPatients with COPD with a smoking history of ≥ 10 pack-years, post-bronchodilator forced expiratory volume in 1 second (FEV1) < 80% and ≥ 30% predicted normal and FEV1/forced vital capacity < 0.70 were enrolled. Patients were randomized to double-blind treatment with NVA237 50 μg once daily or placebo for 26 weeks with inhaled/intranasal corticosteroids or H1 antagonists permitted in patients stabilized on them prior to study entry. The primary outcome measure was trough FEV1 at Week 12.ResultsA total of 822 patients were randomized to NVA237 (n = 552) or placebo (n = 270). Least squares mean (± standard error) trough FEV1 at Week 12 was significantly higher in patients receiving NVA237 (1.408 ± 0.0105 L), versus placebo (1.301 ± 0.0137 L; treatment difference 108 ± 14.8 mL, p < 0.001). Significant improvements in trough FEV1 were apparent at the end of Day 1 and sustained through Week 26. FEV1 was significantly improved in the NVA237 group versus placebo throughout the 24-hour periods on Day 1 and at Weeks 12 and 26, and at all other visits and timepoints. Transition dyspnoea index focal scores and St. George's Respiratory Questionnaire scores were significantly improved with NVA237 versus placebo at Week 26, with treatment differences of 1.04 (p < 0.001) and-2.81 (p = 0.004), respectively. NVA237 significantly reduced the risk of first moderate/severe COPD exacerbation by 31% (p = 0.023) and use of rescue medication by 0.46 puffs per day (p = 0.005), versus placebo. NVA237 was well tolerated and had an acceptable safety profile, with a low frequency of cardiac and typical antimuscarinic adverse effects.ConclusionsOnce-daily NVA237 was safe and well tolerated and provided rapid, sustained improvements in lung function, improvements in dyspnoea, and health-related quality of life, and reduced the risk of exacerbations and the use of rescue medication.Trial registrationClinicalTrials.gov: NCT01005901
SummaryBackground Although the role of immunoglobulin E (IgE) in immunity against helminth parasites is unclear, there is concern that therapeutic antibodies that neutralize IgE (anti-IgE) may be unsafe in subjects at risk of helminth infection. Objective We conducted an exploratory study to investigate the safety of omalizumab (antiIgE) in subjects with allergic asthma and/or perennial allergic rhinitis at high risk of intestinal helminth infection. The primary safety outcome was risk of infections with intestinal helminths during anti-IgE therapy. Methods A randomized, double-blind, placebo-controlled trial was conducted in 137 subjects (12-30 years) at high risk of geohelminth infection. All subjects received pre-study anthelmintic treatment, followed by 52 weeks' treatment with omalizumab or placebo. Results Of the omalizumab subjects 50% (34/68) experienced at least one intestinal geohelminth infection compared with 41% (28/69) of placebo subjects [odds ratio (OR) 1.47, 95% confidence interval (CI) 0.74-2.95, one-sided P = 0.14; OR (adjusted for study visit, baseline infection status, gender and age) 2.2 (0.94-5.15); one-sided P = 0.035], providing some evidence for a potential increased incidence of geohelminth infection in subjects receiving omalizumab. Omalizumab therapy was well tolerated, and did not appear to be associated with increased morbidity attributable to intestinal helminths as assessed by clinical and laboratory adverse events, maximal helminth infection intensities and additional anthelmintic requirements. Time to first infection (OR 1.30, 95% CI 0.79-2.15, one-sided P = 0.15) was similar between treatment groups. Infection severity and response to anthelmintics appeared to be unaffected by omalizumab therapy. Conclusions In this exploratory study of allergic subjects at high risk of helminth infections, omalizumab therapy appeared to be safe and well tolerated, but may be associated with a modest increase in the incidence of geohelminth infection.
Background This randomised, double-blind, placebo controlled, four-period crossover study assessed the efficacy and safety of once-daily QVA149, a dual bronchodilator consisting of the long-acting b 2 -agonist indacaterol and the long-acting muscarinic antagonist glycopyrronium (NVA237), in patients with moderate to severe chronic obstructive pulmonary disease (COPD). Methods Patients (N¼154) were randomly assigned to receive QVA149 (indacaterol/NVA237) 300/50 mg, indacaterol 300 mg, indacaterol 600 mg, or placebo, once daily for 7 days with a 7-day washout period between each treatment. The primary endpoint was trough forced expiratory volume in 1 s (FEV 1 ) (mean of 23 h 15 min and 23 h 45 min post-dose values) on day 7. Other endpoints included trough FEV 1 on day 1, individual time point FEV 1 and monitoring and recording of all adverse events. Results A total of 135 (87.7%) patients completed the study (all randomly assigned patients: mean age 61.7 years, 61.4% male, post-bronchodilator FEV 1 52.2% predicted, FEV 1 /forced vital capacity 47.6%). The estimated treatment difference (95% CI) for trough FEV 1 on day 7 between QVA149 and placebo was 226 ml (192 to 260; p<0.001). The estimated treatment difference between QVA149 and indacaterol 300 and 600 mg was 123 ml (89 to 157; p<0.001) and 117 ml (83 to 150; p<0.001), respectively. The improvements in mean trough FEV 1 exceeded the predefined minimal clinically important differences of 100e140 ml for QVA149 versus placebo and indacaterol. Similar results were observed on day 1. All treatments were well tolerated. Conclusions QVA149 demonstrated rapid and sustained bronchodilation with significant improvements compared with indacaterol monotherapy and placebo in patients with COPD. Clinical trial registration NCT00570778.Bronchodilators are the mainstay for the treatment of chronic obstructive pulmonary disease (COPD). 1The long-acting b 2 -agonists (LABA), formoterol and salmeterol, and the long-acting muscarinic antagonist (LAMA) tiotropium are widely used as maintenance treatment for COPD. When symptoms are not adequately controlled by monotherapy, combining bronchodilators of different classes, in particular an inhaled muscarinic antagonist with a b 2 -agonist, is associated with better outcomes. 1Combining LABA with anticholinergic agents has been shown to be pharmacologically useful because b 2 -agonists decrease the release of acetylcholine, leading to consequent amplification of the bronchial smooth muscle relaxation induced by the anticholinergic agent.2 The addition of an anticholinergic agent can also reduce peripheral bronchoconstrictor effects of acetylcholine, consequently causing amplification of bronchodilation elicited by the b 2 -agonist through direct stimulation of smooth muscle b 2 -adrenoceptors. 2 The superior bronchodilation obtained by combining bronchodilators with different mechanisms of action may be attributed to complementary pharmacodynamic profiles whereby the anticholinergic causes prolonged bronchodilation and the LA...
