          Abstract

          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 (FEV 1) at 12 weeks.

          1,066 patients were randomised, 810 completed the study. At week 12, trough FEV 1 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.

          A long-term evaluation of once-daily inhaled tiotropium in chronic obstructive pulmonary disease.

          Currently available inhaled bronchodilators used as therapy for chronic obstructive pulmonary disease (COPD) necessitate multiple daily dosing. The present study evaluates the long-term safety and efficacy of tiotropium, a new once-daily anticholinergic in COPD. Patients with stable COPD (age 65.2+/-8.7 yrs (mean+/-SD), n=921) were enrolled in two identical randomized double-blind placebo-controlled 1-yr studies. Patients inhaled tiotropium 18 microg or placebo (mean screening forced expiratory volume in one second (FEV1) 1.01 versus 0.99 L, 39.1 and 38.1% of the predicted value) once daily as a dry powder. The primary spirometric outcome was trough FEV1 (i.e. FEV1 prior to dosing). Changes in dyspnoea were measured using the Transition Dyspnea Index, and health status with the disease-specific St. George's Respiratory Questionnaire and the generic Short Form 36. Medication use and adverse events were recorded. Tiotropium provided significantly superior bronchodilation relative to placebo for trough FEV1 response (approximately 12% over baseline) (p<0.01) and mean response during the 3 h following dosing (approximately 22% over baseline) (p<0.001) over the 12-month period. Tiotropium recipients showed less dyspnoea (p<0.001), superior health status scores, and fewer COPD exacerbations and hospitalizations (p<0.05). Adverse events were comparable with placebo, except for dry mouth incidence (tiotropium 16.0% versus placebo 2.7%, p<0.05). Tiotropium is an effective, once-daily bronchodilator that reduces dyspnoea and chronic obstructive pulmonary disease exacerbation frequency and improves health status. This suggests that tiotropium will make an important contribution to chronic obstructive pulmonary disease therapy.

            Effect of tiotropium on outcomes in patients with moderate chronic obstructive pulmonary disease (UPLIFT): a prespecified subgroup analysis of a randomised controlled trial.

            The beneficial effects of pharmacotherapy for chronic obstructive pulmonary disease (COPD) are well established. However, there are few data for treatment in the early stages of the disease. We examined the effect of tiotropium on outcomes in a large subgroup of patients with moderate COPD. The Understanding Potential Long-Term Impacts on Function with Tiotropium (UPLIFT) study was a randomised, double-blind, placebo-controlled trial undertaken in 487 centres in 37 countries. 5993 patients aged 40 years or more with COPD were randomly assigned to receive 4 years of treatment with either once daily tiotropium (18 microg; n=2987) or matching placebo (n=3006), delivered by an inhalation device. Randomisation was by computer-generated blocks of four, with stratification according to study site. In a prespecified subgroup analysis, we investigated the effects of tiotropium in patients with Global Initiative for Chronic Obstructive Lung Disease (GOLD) stage II disease. Primary endpoints were the yearly rates of decline in prebronchodilator forced expiratory volume in 1 s (FEV(1)) and in postbronchodilator FEV(1), beginning on day 30 until completion of double-blind treatment. The analysis included all patients who had at least three measurements of pulmonary function. This study is registered with ClinicalTrials.gov, number NCT00144339. 2739 participants (mean age 64 years [SD 9]) had GOLD stage II disease at randomisation (tiotropium, n=1384; control, n=1355), with a mean postbronchodilator FEV(1) of 1.63 L (SD 0.37; 59% of predicted value). 1218 patients in the tiotropium group and 1157 in the control group had three or more measurements of postbronchodilator pulmonary function after day 30 and were included in the analysis. The rate of decline of mean postbronchodilator FEV(1) was lower in the tiotropium group than in the control group (43 mL per year [SE 2] vs 49 mL per year [SE 2], p=0.024). For prebronchodilator pulmonary function, 1221 patients in the tiotropium group and 1158 in the control group had three or more measurements and were included in the analysis. The rate of decline of mean prebronchodilator FEV(1) did not differ between groups (35 mL per year [SE 2] vs 37 mL per year [SE 2]; p=0.38). Health status, measured with the St George's Respiratory Questionnaire, was better at all timepoints in the tiotropium group than in the control group (p

              Health outcomes following treatment for six months with once daily tiotropium compared with twice daily salmeterol in patients with COPD.

              A study was undertaken to record exacerbations and health resource use in patients with COPD during 6 months of treatment with tiotropium, salmeterol, or matching placebos. Patients with COPD were enrolled in two 6-month randomised, placebo controlled, double blind, double dummy studies of tiotropium 18 micro g once daily via HandiHaler or salmeterol 50 micro g twice daily via a metered dose inhaler. The two trials were combined for analysis of heath outcomes consisting of exacerbations, health resource use, dyspnoea (assessed by the transitional dyspnoea index, TDI), health related quality of life (assessed by St George's Respiratory Questionnaire, SGRQ), and spirometry. 1207 patients participated in the study (tiotropium 402, salmeterol 405, placebo 400). Compared with placebo, tiotropium but not salmeterol was associated with a significant delay in the time to onset of the first exacerbation. Fewer COPD exacerbations/patient year occurred in the tiotropium group (1.07) than in the placebo group (1.49, p<0.05); the salmeterol group (1.23 events/year) did not differ from placebo. The tiotropium group had 0.10 hospital admissions per patient year for COPD exacerbations compared with 0.17 for salmeterol and 0.15 for placebo (not statistically different). For all causes (respiratory and non-respiratory) tiotropium, but not salmeterol, was associated with fewer hospital admissions while both groups had fewer days in hospital than the placebo group. The number of days during which patients were unable to perform their usual daily activities was lowest in the tiotropium group (tiotropium 8.3 (0.8), salmeterol 11.1 (0.8), placebo 10.9 (0.8), p<0.05). SGRQ total score improved by 4.2 (0.7), 2.8 (0.7) and 1.5 (0.7) units during the 6 month trial for the tiotropium, salmeterol and placebo groups, respectively (p<0.01 tiotropium v placebo). Compared with placebo, TDI focal score improved in both the tiotropium group (1.1 (0.3) units, p<0.001) and the salmeterol group (0.7 (0.3) units, p<0.05). Evaluation of morning pre-dose FEV(1), peak FEV(1) and mean FEV(1) (0-3 hours) showed that tiotropium was superior to salmeterol while both active drugs were more effective than placebo. Exacerbations of COPD and health resource usage were positively affected by daily treatment with tiotropium. With the exception of the number of hospital days associated with all causes, salmeterol twice daily resulted in no significant changes compared with placebo. Tiotropium also improved health related quality of life, dyspnoea, and lung function in patients with COPD.
