Eighteen life-long non-smoking severe asthmatics [mean FEV1 1.49 l (51%)] were run-in for 4 weeks on HFA-fluticasone propionate 1000 mg daily, and were subsequently randomised to 4 weeks of either (a) HFA-fluticasone propionate 500 mg BD/ salmeterol 100 mg BD/HFA-tiotropium bromide18 mg od; or (b) fluticasone propionate 500 mg BD/salmeterol 100 mg BD matched placebo. Measurements of spirometry and body plethysmography were made. Adding salmeterol to half the dose of fluticasone led to a mean improvement (95% CI) vs. baseline in morning PEF of 41.5 (14.0–69.0) l/min [po0.05]; and RAWof 0.98 (0.14–1.8) cm H2O/l/s [po0.05]. Adding salmeterol/tiotropium produced similar improvements in PEF and RAW, but also improved FEV1 by 0.17 (0.01–0.32) l [po0.05]; FVC 0.24 (0.05–0.43) l [po0.05] and reduced exhaled NO by 2.86 (0.12–5.6) ppb [po0.05]. RV and TLC were not altered by either treatment; there were no significant changes in symptoms or quality of life compared with baseline. Addition of salmeterol/tiotropium to half the dose of fluticasone afforded small, but significant improvements in pulmonary function. These effects were not associated with commensurate changes in subjective symptoms or quality of life.

Results The use of tiotropium resulted in a superior primary outcome, as compared with a doubling of the dose of an inhaled glucocorticoid, as assessed by measuring the morning peak expiratory flow (PEF), with a mean difference of 25.8 liters per minute (P<0.001) and superiority in most secondary outcomes, including evening PEF, with a difference of 35.3 liters per minute (P<0.001); the proportion of asthmacontrol days, with a difference of 0.079 (P = 0.01); the forced expiratory volume in 1 second (FEV1) before bronchodilation, with a difference of 0.10 liters (P = 0.004); and daily symptom scores, with a difference of −0.11 points (P<0.001). The addition of tiotropium was also noninferior to the addition of salmeterol for all assessed outcomes and increased the prebronchodilator FEV1 more than did salmeterol, with a difference of 0.11 liters (P = 0.003). Conclusions When added to an inhaled glucocorticoid, tiotropium improved symptoms and lung function in patients with inadequately controlled asthma. Its effects appeared to be equivalent to those with the addition of salmeterol. (Funded by the National Heart, Lung, and Blood Institute; ClinicalTrials.gov number
Tiotropium Bromide Step-Up Therapy for Adults with Uncontrolled Asthma NHLBI Asthma Clinical Research Network N Engl J Med 2010;363:1715-26 We report two findings with implications for the treatment of asthma in adults. First, our study shows that the use of tiotropium was superior to a doubling of the dose of an inhaled glucocorticoid for patients whose symptoms were inadequately controlled while they were receiving inhaled beclomethasone alone at a dose of 80 μg twice a day. Second, among patients in our study who were similar to those in trials showing the clinical efficacy of LABA therapy,3,4 tiotropium was noninferior to salmeterol on the basis of predefined criteria, a finding that meets the standards established in the FDA’s draft guidance for industry on noninferiority clinical trials.22

FEV1 Tiotropium (5μg) n:107 Tiotropium (10μg) Plasebo 8 hafta Tiotropium improves lung function in patients with severe uncontrolled asthma: A randomized controlled trial H.A.M.Kerstjens J Allergy Clin Immunol 2011;128:308-14 n:107 Yüksek doz İCS+LABA Kontrolsüz ağır astım Tiotropium (5μg) FEV1 8 hafta Tiotropium (10μg) Plasebo Crossover LAMA as add on to ICS/LABA Background: Some patients with severe asthma remain symptomatic and obstructed despite maximal recommended treatment. Tiotropium, a long-acting inhaled anticholinergic agent, might be an effective bronchodilator in such patients. Objective: We sought to compare the efficacy and safety of 2 doses of tiotropium (5 and 10 mg daily) administered through the Respimat inhaler with placebo as add-on therapy in patients with uncontrolled severe asthma (Asthma Control Questionnaire score, >1.5; postbronchodilator FEV1, <80% of predicted value) despite maintenance treatment with at least a high-dose inhaled corticosteroid plus a long-acting b2-agonist. Methods: This was a randomized, double-blind, crossover study with three 8–week treatment periods. The primary end point was peak FEV1 at the end of each treatment period. Results: Of 107 randomized patients (54% female patients; mean, 55 years of age; postbronchodilator FEV1, 65% of predicted value), 100 completed all periods. Peak FEV1 was significantly higher with 5 mg (difference, 139 mL; 95% CI, 96- 181 mL) and 10 mg (difference, 170 mL; 95% CI, 128–213 mL) of tiotropium than with placebo (both P < .0001). There was no significant difference between the active doses. Trough FEV1 at the end of the dosing interval was higher with tiotropium (5 mg: 86 mL [95% CI, 41-132 mL]; 10 mg: 113 mL [95% CI, 67-159 mL]; both P < .0004). Daily home peak expiratory flow measurements were higher with both tiotropium doses. There were no significant differences in asthma-related health status or symptoms. Adverse events were balanced across groups except for dry mouth, which was more common on 10 mg of tiotropium. Conclusion: The addition of once-daily tiotropium to asthma treatment, including a high-dose inhaled corticosteroid plus a long-acting b2-agonist, significantly improves lung function over 24 hours in patients with inadequately controlled, severe, persistent asthma.

Methods In two replicate, randomized, controlled trials involving 912 patients with asthma who were receiving inhaled glucocorticoids and LABAs, we compared the effect on lung function and exacerbations of adding tiotropium (a total dose of 5 μg) or placebo, both delivered by a soft-mist inhaler once daily for 48 weeks. All the patients were symptomatic, had a post-bronchodilator forced expiratory volume in 1 second (FEV1) of 80% or less of the predicted value, and had a history of at least one severe exacerbation in the previous year. Results The patients had a mean baseline FEV1 of 62% of the predicted value; the mean age was 53 years. At 24 weeks, the mean (±SE) change in the peak FEV1 from baseline was greater with tiotropium than with placebo in the two trials: a difference of 86±34 ml in trial 1 (P = 0.01) and 154±32 ml in trial 2 (P<0.001). The predose (trough) FEV1 also improved in trials 1 and 2 with tiotropium, as compared with placebo: a difference of 88±31 ml (P = 0.01) and 111±30 ml (P<0.001), respectively. The addition of tiotropium increased the time to the first severe exacerbation (282 days vs. 226 days), with an overall reduction of 21% in the risk of a severe exacerbation (hazard ratio, 0.79; P = 0.03). No deaths occurred; adverse events were similar in the two groups. Conclusions In patients with poorly controlled asthma despite the use of inhaled glucocorticoids and LABAs, the addition of tiotropium significantly increased the time to the first severe exacerbation and provided modest sustained bronchodilation.

Predictors of response to tiotropium versus salmeterol in asthmatic adults National Heart, Lung, and Blood Institute’s Asthma Clinical Research Network J Allergy Clin Immunol 2013:132;1068-1074 Tiotropiuma daha iyi yanıt veren hasta alt grupları Kolinerjik tonusu yüksek hastalar (İstirahat kalp hızı düşük olanlar) Genç hastalar Salbutamol veya ipratropium ile reversibilitesi olanlar Tiotropium yanıtını etkilemeyen faktörler Cinsiyet Atopi IgE düzeyi Balgam eozinofilisi FeNO Astım süresi BMI Definitive recommendations concerning how to translate these findings into clinical practice cannot be made on the basis of these observations alone. Clearly, the findings need to be replicated in an independent study. However, if the findings were replicated, we could suggest that if a patient with asthma still has suboptimal asthma control after a trial of ICSs alone (ie, has asthma symptoms or rescue b-agonist use most days of the week and/or >2 awakenings per week for asthma and/or compromised lung function [FEV1 <70% of predicted value]), he or she should undergo spirometry before and after administration of 4 puffs of albuterol. Patients with airway obstruction, as demonstrated by a reduced FEV1/FVC ratio, a positive response to albuterol, or both, should be good candidates for treatment with tiotropium as an add-on therapy. Whether this strategy should be reserved for patients in whom combination ICS-LABA therapy ‘‘fails’’ or whether physicians and patients should have the option of adding either tiotropium or a LABA to an ICS when monotherapy does not produce adequate asthma control awaits further investigation. Background: Tiotropium has activity as an asthma controller. However, predictors of a positive response to tiotropium have not been described. Objective: We sought to describe individual and differential responses of asthmatic patients to salmeterol and tiotropium when added to an inhaled corticosteroid, as well as predictors of a positive clinical response. Methods: Data from the double-blind, 3-way, crossover National Heart, Lung, and Blood Institute’s Asthma Clinical Research Network’s Tiotropium Bromide as an Alternative to Increased Inhaled Glucocorticoid in Patients Inadequately Controlled on a Lower Dose of Inhaled Corticosteroid (ClinicalTrials.gov number, NCT00565266) trial were analyzed for individual and differential treatment responses to salmeterol and tiotropium and predictors of a positive response to the end points FEV1, morning peak expiratory flow (PEF), and asthma control days (ACDs). Results: Although approximately equal numbers of patients showed a differential response to salmeterol and tiotropium in terms of morning PEF (n 5 90 and 78, respectively) and ACDs (n 5 49 and 53, respectively), more showed a differential response to tiotropium for FEV1 (n 5 104) than salmeterol (n 5 62). An acute response to a short-acting bronchodilator, especially albuterol, predicted a positive clinical response to tiotropium for FEV1 (odds ratio, 4.08; 95% CI, 2.00-8.31; P < .001) and morning PEF (odds ratio, 2.12; 95% CI, 1.12-4.01; P 5 0.021), as did a decreased FEV1/forced vital capacity ratio (FEV1 response increased 0.39% of baseline for every 1% decrease in FEV1/forced vital capacity ratio). Higher cholinergic tone was also a predictor, whereas ethnicity, sex, atopy, IgE level, sputum eosinophil count, fraction of exhaled nitric oxide, asthma duration, and body mass index were not. Conclusion: Although these results require confirmation, predictors of a positive clinical response to tiotropium include a positive response to albuterol and airway obstruction, factors that could help identify appropriate patients for this therapy.

However, improvements were independent of other factors that were analyzed, including geographic region, level of reversibility, age (post hoc), body-mass index, allergic status, asthma duration, ACQ-7 score at baseline, and use of systemic glucocorticoids in the year before trial enrollment. Similar results were observed in the analysis of the time to the first severe exacerbation

Additive role of tiotropium in severe asthmatics and Arg16Gly in ADRB2 as a potential marker to predict response H.W. Park Allergy 2009: 64: 778–783 This study demonstrates that as many as 30% of severe asthmatics treated with a combination of high-dose inhaled corticosteroid and long-acting b2 agonist responded to the addition of tiotropium. The exacerbation rate for 143 patients (excluding 17 patients who were noncompliant and withdrew enrollment) in this study was 1.4 events/100 patients/year. Meanwhile, the exacerbation rate of the same asthmatics in the preceding year (based on the review of medical records) was 48.2 events/100 patients/year. Exacerbation rate was not a primary outcome and thus the present study was not powered to evaluate effect of tiotropium on exacerbations. However, a dramatic fall in exacerbation rate suggested a probable role of tiotropium additive to lung function improvement.
