The lung function profile of once-daily tiotropium and olodaterol via Respimat® is superior to that of twice-daily salmeterol and fluticasone propionate via Accuhaler® (ENERGITO® study)

Background: Tiotropium + olodaterol has demonstrated improvements beyond lung function benefits in a large Phase III clinical program as a once-daily maintenance treatment for COPD and may be a potential option for the initiation of maintenance treatment in COPD. Despite guideline recommendations that combined long-acting beta(2)-agonists and inhaled corticosteroids should only be used in individuals at high risk of exacerbation, there is substantial use in individuals at lower risk. This raises the question of the comparative effectiveness of this combination as maintenance treatment in this group compared to other combination regimens. Objective: The study aimed to assess the effect on lung function of once-daily tiotropium + olodaterol versus twice-daily salmeterol + fluticasone propionate in all participants with Global initiative for chronic Obstructive Lung Disease 2 or 3 (moderate to severe) COPD. Methods: This was a randomized, double-blind, double-dummy, four-treatment, complete crossover study in which participants received once-daily tiotropium + olodaterol (5/5 mu g and 2.5/5 mu g) via Respimat (R) and twice-daily salmeterol + fluticasone propionate (50/500 mu g and 50/250 mu g) via Accuhaler (R) for 6 weeks. The primary end point was change in forced expiratory volume in 1 second (FEV1) area under the curve from 0 hour to 12 hours (AUC(0-12)) relative to the baseline after 6 weeks. Results: Tiotropium + olodaterol 5/5 mu g and 2.5/5 mu g demonstrated statistically significant improvements in FEV1 AUC(0-12) compared to salmeterol + fluticasone propionate (improvements from baseline were 317 mL and 295 mL with tiotropium + olodaterol 5/5 mu g and 2.5/5 mu g, and 188 mL and 192 mL with salmeterol + fluticasone propionate 50/500 mu g and 50/250 mu g, respectively). Tiotropium + olodaterol was superior to salmeterol + fluticasone propionate in lung function secondary end points, including FEV1 area under the curve from 0 hour to 24 hours (AUC(0-24)). Conclusion: Once-daily tiotropium + olodaterol in participants with moderate-to-severe COPD provided superior lung function improvements to twice-daily salmeterol + fluticasone propionate. Dual bronchodilation can be considered to optimize lung function in individuals requiring maintenance treatment for COPD

The 24-h lung-function profile of once-daily tiotropium and olodaterol fixed-dose combination in chronic obstructive pulmonary disease

Background: This study investigated the effects on 24-h lung function and lung volume of a once-daily fixed-dose combination (FDC) of the long-acting muscarinic antagonist tiotropium and the long-acting beta(2)-agonist olodaterol in patients with chronic obstructive pulmonary disease. Methods: This was a randomised, double-blind, placebo-controlled, Phase III trial with an incomplete crossover design. Patients received four of the following six treatment options for 6 weeks each: placebo, olodaterol 5 mu g, tiotropium 2.5 mu g, tiotropium 5 mu g, tiotropium + olodaterol FDC 2.5/5 mu g and tiotropium + olodaterol FDC 5/5 mu g, all delivered via the Respimat (R) inhaler. The primary end point was forced expiratory volume in 1 s (FEV1) area under the curve from 0 to 24 h (AUC(0-24)) response after 6 weeks of treatment; key secondary end points were FEV1 AUC from 0 to 12 h and AUC from 12 to 24 h, and further end points included lung-volume parameters measured using body plethysmography (subset of patients), measures of peak and trough FEV1, and incidence of adverse events. Results: A significant improvement in FEV1 AUC(0-24) response was observed with tiotropium + olodaterol 5/5 mu g and 2.5/5 mu g versus placebo and monotherapies after 6 weeks of treatment; mean response with tiotropium + olodaterol 5/5 mu g versus placebo was 0.280 L (p < 0.0001). Differences to monotherapies with tiotropium + olodaterol 5/5 mu g were 0.115 L versus olodaterol 5 mu g, 0.127 L versus tiotropium 2.5 mu g and 0.110 L versus tiotropium 5 mu g (p < 0.0001 for all comparisons). Secondary end points supported these data. No safety concerns were identified. Conclusions: Overall, this study demonstrated improvements in lung function over 24 h with an FDC of tiotropium + olodaterol over tiotropium or olodaterol alone, with no observed difference in tolerability.

Effect of cetirizine dihydrochloride on the airway response to hypertonic saline aerosol in patients with chronic obstructive pulmonary disease (COPD)

Hypertonic saline aerosol can elicit airway obstruction in patients with moderate or severe COPD. In the present study we assessed whether cetirizine dihydrochloride is capable of modulating this response. After a screening visit, 20 patients with COPD (mean FEV(1) 49% pred) were treated with cetirizine 10mg daily or placebo over 1 week in a randomized, double-blind, cross-over fashion and measurements performed at the end of treatment periods. At each visit, patients were challenged by 3% saline aerosol (screening: 0.9%) over 5 min after prior inhalation of salbutamol, and 45 min later sputum was obtained after inhalation of 0.9% saline. Lung function was quantified in terms of forced expiratory (FEV(1)) and inspiratory (FIV(1)) volumes. Spirometric values did not differ between visits and salbutamol-induced bronchodilation was not altered by cetirizine. Compared to baseline or post-salbutamol values, the saline-induced fall in FEV(1) was smallest at screening (P <0.01), without a significant difference between treatments. Regarding FIV(1), however, the percent fall from baseline was higher after placebo (Delta=-10.1%; P <0.05) compared to screening (0.4%) or cetirizine (-4.3%). Sputum composition showed no significant differences except for a tendency towards reduced concentrations of alpha(2)-macroglobulin after cetirizine compared to placebo (P=0.045). The present data indicate some, though small, effects of the H1 receptor antagonist cetirizine on hypertonic saline-induced airway obstruction in patients with moderate-to-severe COPD. In view of the mechanisms involved, it is an open question whether stronger effects can be elicited with higher doses and whether such effects would translate into clinical benefits, e.g. during exacerbation

Effects of baseline symptom burden on treatment response in COPD

Rationale: In symptomatic patients with COPD, the decision whether to initiate maintenance treatment with a single agent or a combination of long-acting bronchodilators remains unclear. Objective: To investigate whether baseline symptomatic status influences response to tiotropium/olodaterol treatment. Materials and methods: Post hoc analysis of the randomized OTEMTO® studies (NCT01964352; NCT02006732), in which patients with moderate-to-severe COPD received placebo, tiotropium 5 µg, tiotropium/olodaterol 2.5/5 µg, or tiotropium/olodaterol 5/5 µg once daily for 12 weeks via the Respimat® inhaler (Boehringer Ingelheim, Ingelheim am Rhein, Germany). Impact of baseline symptomatic status (modified Medical Research Council [mMRC] score) on response to treatment with tiotropium/olodaterol 5/5 µg, tiotropium 5 µg, or placebo at Week 12 was assessed by St George's Respiratory Questionnaire (SGRQ) total score and response rate, transition dyspnea index (TDI) focal score and response rate, and trough forced expiratory volume in 1 second response. Results: Tiotropium/olodaterol improved SGRQ total scores and response rates compared with placebo and tiotropium for patients with baseline mMRC scores 0-1 and ≥2. For tiotropium/olodaterol vs tiotropium, greater improvements were observed for patients with mMRC ≥2 (SGRQ score adjusted mean treatment difference -3.44 [95% CI: -5.43, -1.46]; P=0.0007; SGRQ response rate ORs 2.09 [95% CI: 1.41, 3.10]; P=0.0002). Dyspnea, measured by TDI score, was consistently improved with tiotropium/olodaterol vs placebo for patients with mMRC scores 0-1 and ≥2 (adjusted mean treatment difference 1.63 [95% CI: 1.06, 2.20]; P<0.0001 and 1.60 [95% CI: 1.09, 2.10]; P<0.0001, respectively). In patients with mMRC scores 0-1 and ≥2, tiotropium/olodaterol consistently improved TDI response rate and lung function vs placebo and tiotropium. Conclusions: Patients with COPD with more severe baseline dyspnea appear to derive greater health status benefit with tiotropium/olodaterol compared with tiotropium alone

Tiotropium + olodaterol shows clinically meaningful improvements in quality of life.

Tiotropium + olodaterol improves lung function and symptoms compared to monotherapies in chronic obstructive pulmonary disease (COPD). The OTEMTO 1 and 2 studies investigated the effects of tiotropium + olodaterol on lung function and health-related quality of life compared to placebo in patients with moderate to severe COPD

Composite endpoints in COPD: clinically important deterioration in the UPLIFT trial

BACKGROUND: Assessments of lung function, exacerbations and health status are common measures of chronic obstructive pulmonary disease (COPD) progression and treatment response in clinical trials. We hypothesised that a composite endpoint could more holistically assess clinically important deterioration (CID) in a COPD clinical trial setting. METHODS: A composite endpoint was tested in a post hoc analysis of 5652 patients with Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2–4 COPD from the 4-year UPLIFT study. Patients received tiotropium 18 μg or placebo. RESULTS: The composite endpoint included time to first confirmed decrease in trough forced expiratory volume in 1 s (FEV1) ≥100 mL, confirmed increase in St. George’s Respiratory Questionnaire (SGRQ) total score ≥ 4 units, or moderate/severe exacerbation. Most patients (&gt; 80%) experienced CID, with similar incidence among GOLD subgroups. Most confirmed trough FEV1 (74.6–81.6%) and SGRQ (72.3–78.1%) deteriorations were sustained across the study and in all GOLD subgroups. Patients with CID more frequently experienced subsequent exacerbation (hazard ratio [HR] 1.79; 95% confidence interval [CI] 1.67, 1.92) or death (HR 1.21; 95% CI 1.06, 1.39) by Month 6. CID was responsive to bronchodilator treatment. CONCLUSIONS Composite endpoints provide additional information on COPD progression and treatment effects in clinical trials

Tiotropium and olodaterol fixed-dose combination versus mono-components in COPD (GOLD 2-4)

Efficacy and safety of tiotropium+olodaterol fixed-dose combination (FDC) compared with the mono-components was evaluated in patients with moderate to very severe chronic obstructive pulmonary disease (COPD) in two replicate, randomised, double-blind, parallel-group, multicentre, phase III trials. Patients received tiotropium+ olodaterol FDC 2.5/5 mu g or 5/5 mu g, tiotropium 2.5 mu g or 5 mu g, or olodaterol 5 mu g delivered once-daily via Respimat inhaler over 52 weeks. Primary end points were forced expiratory volume in 1 s (FEV1) area under the curve from 0 to 3 h (AUC0-3) response, trough FEV1 response and St George's Respiratory Questionnaire (SGRQ) total score at 24 weeks. In total, 5162 patients (2624 in Study 1237.5 and 2538 in Study 1237.6) received treatment. Both FDCs significantly improved FEV1 AUC0-3 and trough FEV1 response versus the mono-components in both studies. Statistically significant improvements in SGRQ total score versus the mono-components were only seen for tiotropium+ olodaterol FDC 5/5 mu g. Incidence of adverse events was comparable between the FDCs and the mono-components. These studies demonstrated significant improvements in lung function and health-related quality of life with once-daily tiotropium+ olodaterol FDC versus mono-components over 1 year in patients with moderate to very severe COPD

Effects of tiotropium + olodaterol versus tiotropium or placebo by COPD disease severity and previous treatment history in the OTEMTO® studies

Abstract Background As lung function declines rapidly in the early stages of chronic obstructive pulmonary disease (COPD), the effects of bronchodilators in patients with moderate disease and those who have not previously received maintenance therapy are of interest. OTEMTO® 1 and 2 were two replicate, 12-week, Phase III studies investigating the benefit of tiotropium + olodaterol on lung function and quality of life in patients with moderate to severe disease. Post hoc analyses were performed to assess the benefits for patients according to disease severity and treatment history. Methods Four subgroup analyses were performed: Global initiative for chronic Obstructive Lung Disease (GOLD) 2/3, GOLD A/B/C/D, treatment naive/not treatment naive and receiving inhaled corticosteroids (ICS) at baseline/not receiving ICS at baseline. Primary end points were change in forced expiratory volume in 1 s (FEV1) area under the curve from 0 to 3 h response, change in trough FEV1 and St George’s Respiratory Questionnaire (SGRQ) total score. Transition Dyspnoea Index (TDI) focal score was a secondary end point, and SGRQ and TDI responder analyses were further end points; all were assessed at 12 weeks. Results In all subgroups, patients receiving tiotropium + olodaterol responded better overall than those receiving tiotropium monotherapy. Improvements with tiotropium + olodaterol over placebo or tiotropium monotherapy were noted across GOLD 2/3 and GOLD A/B/C/D; however, improvements in SGRQ total score were most evident in the GOLD B subgroup. Moreover, lung-function outcomes were generally greater in those patients who had been receiving previous long-acting bronchodilator and/or ICS maintenance treatment. Conclusions These data suggest that tiotropium + olodaterol should be considered as a treatment option in patients with moderate COPD who are initiating maintenance therapy, as well as those with more severe disease.
