Randomized, Double-Blind, Dose-Finding Study for Tiotropium when Added to Olodaterol, Administered via the Respimat® Inhaler in Patients with Chronic Obstructive Pulmonary Disease.

ABSTRACT:

Introduction

Combining long-acting muscarinic antagonists (LAMAs) and long-acting β2-agonists (LABAs) is beneficial in chronic obstructive pulmonary disease (COPD), as the two classes of bronchodilator have complementary modes of action. The optimal dose for the fixed-dose combination of the LAMA tiotropium and the LABA olodaterol needed to be determined. In this phase II trial, the dose response of tiotropium on top of olodaterol was investigated in a free-dose combination, while other phase II studies have explored different doses of olodaterol on top of tiotropium, with both drugs delivered using the Respimat(®) inhaler.

Methods

This was a double-blind incomplete crossover trial in which 233 patients with moderate or severe COPD were randomized to receive four out of eight free-dose combinations of olodaterol (5 or 10 µg) and tiotropium (1.25, 2.5, or 5 µg) or placebo for 4 weeks each. Primary end point was trough forced expiratory volume in 1 s (FEV1) change from baseline (response) after 4 weeks.

Results

Addition of tiotropium 1.25, 2.5, and 5 µg to olodaterol 5 µg increased mean trough FEV1 response by 0.054, 0.065, and 0.084 L, respectively; addition of tiotropium 1.25, 2.5, and 5 µg to olodaterol 10 µg increased mean trough FEV1 response by 0.051, 0.083, and 0.080 L, respectively. All treatments were well tolerated and incidence of adverse events was similar with all treatments.

Conclusions

Overall, a dose response for tiotropium on top of both doses of olodaterol was observed, with increasing improvements in trough FEV1 compared to olodaterol alone as the tiotropium dose was increased.

Project description:IntroductionClinical studies have shown significant improvements in exercise capacity in patients with chronic obstructive pulmonary disease (COPD) who are treated with a tiotropium/olodaterol fixed-dose combination (FDC). However, the effects of this treatment, which is administered in a single device, on physical functioning in a real-life setting of patients with COPD had not been fully determined.MethodsAn open-label, observational study was conducted in 309 patients with COPD from 29 sites across Italy who received tiotropium/olodaterol FDC for 6 weeks. Physical functioning was evaluated using the Physical Functioning Questionnaire (PF-10). The primary endpoint was the proportion of patients with therapeutic success, defined as a ten-point increase in the PF-10 score from the baseline visit. Secondary endpoints were absolute changes in PF-10 score from baseline visit, the patient's general condition assessed by the Physician's Global Evaluation (PGE) score, and patient satisfaction with treatment, inhaling and handling of the device.ResultsAccording to the Global Initiative for Chronic Obstructive Lung Disease (GOLD) multimodality assessment, most patients were allocated to groups B (44.4%) and D (24.5%). Comorbidities were present in 73.9% of the patients. The primary endpoint was reached in more than half of the patients (52.5%), especially in groups B and D of GOLD. Patients' satisfaction with treatment, inhaling and handling of device was high, with a range of more than 86% to more than 89%, and very high in both groups B and D. The rates of drug-related adverse events were very low.ConclusionsThis real-life study showed that the tiotropium/olodaterol FDC treatment delivered via the Respimat device improves physical functioning and general patients' condition and is associated with a high degree of satisfaction and very low rates of drug-related adverse events, regardless of the group they belong to and their comorbidities.Clinical trial idNCT03003494.

Project description:IntroductionTiotropium is prescribed for the treatment of chronic obstructive pulmonary disease (COPD) and delivered via HandiHaler(®) (18 μg once daily) or Respimat(®) Soft Mist™ inhaler (5 μg once daily). The recent TIOtropium Safety and Performance In Respimat(®) (TIOSPIR™) study demonstrated that both exhibit similar safety profiles. This analysis provides an updated comprehensive safety evaluation of tiotropium(®) using data from placebo-controlled HandiHaler(®) and Respimat(®) trials.MethodsPooled analysis of adverse event (AE) data from tiotropium HandiHaler(®) 18 μg and Respimat(®) 5 μg randomized, double-blind, parallel-group, placebo-controlled, clinical trials in patients with COPD (treatment duration ≥4 weeks). Incidence rates, rate ratios (RRs), and 95% confidence intervals (CIs) were determined for HandiHaler(®) and Respimat(®) trials, both together and separately.ResultsIn the 28 HandiHaler(®) and 7 Respimat(®) trials included in this analysis, 11,626 patients were treated with placebo and 12,929 with tiotropium, totaling 14,909 (12,469 with HandiHaler(®); 2,440 with Respimat(®)) patient-years of tiotropium exposure. Mean age was 65 years, and mean prebronchodilator forced expiratory volume in 1 second (FEV1) was 1.16 L (41% predicted). The risk (RR [95% CI]) of AEs (0.90 [0.87, 0.93]) and of serious AEs (SAEs) (0.94 [0.89, 0.99]) was significantly lower in the tiotropium than in the placebo group (HandiHaler(®) and Respimat(®) pooled results), and there was a numerically lower risk of fatal AEs (FAEs) (0.90 [0.79, 1.01]). The risk of cardiac AEs (0.93 [0.85, 1.02]) was numerically lower in the tiotropium group. Incidences of typical anticholinergic AEs, but not SAEs, were higher with tiotropium. Analyzed separately by inhaler, the risks of AE and SAE in the tiotropium groups remained lower than in placebo and similarly for FAEs.ConclusionThis analysis indicates that tiotropium is associated with lower rates of AEs, SAEs, and similar rates of FAEs than placebo when delivered via HandiHaler(®) or Respimat(®) (overall and separately) in patients with COPD.

Project description:BackgroundTiotropium Safety and Performance in Respimat® (TIOSPIR®) compared the safety and efficacy of tiotropium Respimat® and tiotropium HandiHaler® in patients with chronic obstructive pulmonary disease (COPD). A prespecified spirometry substudy compared the lung function efficacy between treatment groups.MethodsTIOSPIR® was a large-scale, long-term (2.3-year), event-driven, randomized, double-blind, parallel-group trial of 17,135 patients with COPD. In the spirometry substudy, trough forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) were measured at baseline and every 24 weeks for the duration of the trial.ResultsThe substudy included 1370 patients who received once-daily tiotropium Respimat® 5 μg (n = 461), 2.5 μg (n = 464), or tiotropium HandiHaler® 18 μg (n = 445). Adjusted mean trough FEV1 (average 24-120 weeks) was 1.285, 1.258, and 1.295 L in the Respimat® 5 μg, 2.5 μg, and HandiHaler® 18 μg groups (difference versus HandiHaler® [95 % CI]: -10 [-38, 18] mL for Respimat® 5 μg and, -37 [-65, -9] mL for Respimat® 2.5 μg); achieving noninferiority to tiotropium HandiHaler® 18 μg for tiotropium Respimat® 5 but not for 2.5 μg (prespecified analysis). Adjusted mean trough FVC was 2.590, 2.544, and 2.593 L in the Respimat® 5 μg, 2.5 μg, and HandiHaler® 18 μg groups. The rates of FEV1 decline over 24 to 120 weeks were similar for the three treatment arms (26, 40, and 34 mL/year for the tiotropium Respimat® 5-μg, 2.5-μg, and HandiHaler® 18-μg groups). The rate of FEV1 decline in GOLD I + II patients was greater than in GOLD III + IV patients (46 vs. 23 mL/year); as well as in current versus ex-smokers, in patients receiving combination therapies at baseline versus not, and in those experiencing an exacerbation during the study versus not.ConclusionsThe TIOSPIR® spirometry substudy showed that tiotropium Respimat® 5 μg was noninferior to tiotropium HandiHaler® 18 μg for trough FEV1, but Respimat® 2.5 μg was not. Tiotropium Respimat® 5 μg provides similar bronchodilator efficacy to tiotropium HandiHaler® 18 μg with comparable rates of FEV1 decline. The rate of FEV1 decline varied based on disease severity, with a steeper rate of decline observed in patients with moderate airway obstruction.Trial registrationNCT01126437.

Project description:BackgroundPatients with chronic obstructive pulmonary disease (COPD) show signs of reduced physical activity from the early stages of the disease, impacting morbidity and mortality. Data suggest treatment with tiotropium, a long-acting muscarinic antagonist, and olodaterol, a long-acting ß2-agonist (LABA), as monotherapies and in combination, increases exercise capacity. This study assessed the effects of fixed-dose tiotropium/olodaterol (delivered via Respimat®) on physical function in Global Initiative for Chronic Obstructive Lung Disease A-D patients requiring long-acting dual bronchodilation treatment in a real-world setting.MethodsThis open-label, single arm, noninterventional study measured changes in physical function in COPD patients treated with tiotropium/olodaterol 5/5 μg for approximately 6 weeks (between Visit 1 [baseline] and Visit 2). Primary end point was therapeutic success, defined as a minimum 10-point increase in Physical Functioning Questionnaire (PF-10) score. Secondary end points included change in PF-10 from Visit 1 to Visit 2, the patient's general condition (measured by Physician's Global Evaluation score) at Visit 1 and Visit 2, and patient satisfaction with treatment delivered via the Respimat® device (assessed by Patient Satisfaction Questionnaire) at study end.ResultsTherapeutic success was observed in 51.5% of 1578 patients (95% confidence interval [CI] 49.0, 54.0) after approximately 6 weeks of treatment with tiotropium/olodaterol. Mean change in PF-10 score between Visit 1 and Visit 2 was 11.6 points (95% CI 10.7, 12.6). Patient general condition improved as indicated by a general improvement in scores between visits. Most patients were very satisfied or satisfied with tiotropium/olodaterol treatment (82.5%), inhalation (87.5%), and handling of Respimat® (85.2%). One percent of patients reported an investigator-defined drug-related adverse events (AE).ConclusionTiotropium/olodaterol treatment improved physical functioning in COPD patients. An associated increase in patient general condition was observed. Most patients were very satisfied or satisfied with tiotropium/olodaterol treatment, inhaling, and handling of the Respimat® device. No unexpected drug-related AE occurred.

Project description:BackgroundTiotropium + 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 β2-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.ObjectiveThe 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.MethodsThis was a randomized, double-blind, double-dummy, four-treatment, complete crossover study in which participants received once-daily tiotropium + olodaterol (5/5 µg and 2.5/5 µg) via Respimat(®) and twice-daily salmeterol + fluticasone propionate (50/500 µg and 50/250 µg) via Accuhaler(®) 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 (AUC0-12) relative to the baseline after 6 weeks.ResultsTiotropium + olodaterol 5/5 µg and 2.5/5 µg demonstrated statistically significant improvements in FEV1 AUC0-12 compared to salmeterol + fluticasone propionate (improvements from baseline were 317 mL and 295 mL with tiotropium + olodaterol 5/5 µg and 2.5/5 µg, and 188 mL and 192 mL with salmeterol + fluticasone propionate 50/500 µg and 50/250 µg, 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 (AUC0-24).ConclusionOnce-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.
