Cardiovascular Events and All-Cause Mortality in Patients With Chronic Obstructive Pulmonary Disease Using Olodaterol and Other Long-Acting Beta2-Agonists.

[PMID: 35320605 PMCID: PMC9545725 DOI: 10.1002/pds.5432] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2021] [Revised: 01/12/2022] [Accepted: 03/18/2022] [Indexed: 11/10/2022]
Abstract
PURPOSE We examined the effect of olodaterol on the risk of myocardial ischaemia, cardiac arrhythmia, and all-cause mortality compared with use of other long-acting beta2-agonists (LABAs). Channelling bias was also explored. METHODS This Danish population-based cohort study used data linked from registries of hospital diagnoses, outpatient dispensings, and deaths. It included patients (aged ≥40 years) with a diagnosis of chronic obstructive pulmonary disease (COPD) who initiated olodaterol or another LABA. Using matching and propensity score (PS) stratification, we calculated adjusted incidence rate ratios (IRRs) using Poisson regression, followed by several additional analyses to evaluate and control channelling bias. RESULTS The IRRs of cardiac arrhythmias or myocardial ischaemia among users of olodaterol (n=14,239) compared to users of other LABA (n=51,167) ranged from 0.96 to 1.65 in various analyses, although some estimates had low precision. Initial analysis suggested an increased risk for death with olodaterol compared with other LABAs (IRR, 1.63; 95% CI, 1.44-1.84). Because olodaterol prescribing was associated with COPD severity, the mortality association was attenuated by using different methods of tighter confounding control: the IRRs were 1.26 (95% CI, 0.97-1.64) among LABA-naïve LABA/LAMA users without recent COPD hospitalisation; 1.27 (95% CI, 1.03-1.57) in a population with additional trimming from the tails of the PS distribution; and 1.32 (95% CI, 1.19-1.48) after applying overlap-weights analysis. CONCLUSIONS Olodaterol users had a similar risk for cardiac arrhythmias or myocardial ischaemia as other LABA users. The observed excess all-cause mortality associated with olodaterol use could be due to uncontrolled channelling bias.

Cheng SL. Comparison of Effectiveness Using Different Dual Bronchodilator Agents in Chronic Obstructive Pulmonary Disease Treatment. J Clin Med 2021; 10:jcm10122649. [PMID: 34208599 PMCID: PMC8235085 DOI: 10.3390/jcm10122649] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2021] [Revised: 06/11/2021] [Accepted: 06/14/2021] [Indexed: 11/22/2022] Open
Abstract
The effectiveness and safety of fixed dual long-acting bronchodilators for chronic obstructive pulmonary disease (COPD) patients have been well established; however, there is a paucity of clinical effectiveness comparison in patients with COPD treatment. The aim of the current study was to compare the effectiveness of three once-daily dual bronchodilator agents in patients with COPD. Patients with diagnosed COPD and treated with a long-acting beta-agonist (LABA) + long-acting muscarinic antagonist (LAMA) fixed-dose combination therapy (UME/VIL (umeclidinium and vilanterol inhalation powder), IND/GLY (indacaterol and glycopyrronium), and TIO/OLO (tiotropium and olodaterol)) were enrolled in this retrospective study over a period of 12 months. Effectiveness assessments were evaluated using a COPD assessment test (CAT) and lung function parameters. Besides, times for acute exacerbation were also assessed. The enrolled patients’ number was 177 in IND/GLY, 176 in UME/VIL and 183 in TIO/OLO. Lung function measurements with FEV1 had significantly improved for patients using TIO/OLO (98.7 mL) compared to those of IND/GLY (65.2 mL) and UME/VIL (64.4 mL) (p < 0.001). CAT scores were also significantly decreased in patients treated with TIO/OLO (CAT down 5.6) than those with IND/GLY (3.8) and UME/VIL (3.9) (p = 0.03). Acute exacerbation was also reduced in patients using TIO/OLO (4.9%) compared with those using IND/GLY (10.2%) and UME/VIL (11.9%) (p = 0.01). Significant improvement in pulmonary function, symptoms were demonstrated after 12 months of LABA/LAMA fixed-dose combination therapy with three different treatment options. TIO/OLO demonstrated higher therapeutic effects compared with UME/VIL or IND/GLY. Determining clinical relevance will require a well-designed randomized controlled trial.

Abstract
Background Patients with chronic obstructive pulmonary disease (COPD) and cardiovascular comorbidities may have an increased risk of medication-related cardiac arrhythmias. We therefore performed an analysis of Holter electrocardiogram (ECG) data from two large, long-term, controlled clinical COPD trials to investigate whether tiotropium/olodaterol increased the risk of cardiac arrhythmia and mean heart rate. Methods We analyzed Holter ECG data from a representative subset of patients (N=506) from the two pooled replicate studies (TONADO 1 and 2) assessing tiotropium/olodaterol 5/5 µg therapy versus tiotropium 5 µg or olodaterol 5 µg monotherapy, inhaled once daily (two single inhalations) using the Respimat® Soft Mist™ inhaler device. Additionally, major adverse cardiac events (MACE) with tiotropium/olodaterol were assessed versus the respective monotherapies. Results After 12 weeks of treatment, there was no difference in the number of patients who had an increase or decrease from baseline in 24-hour supraventricular premature beats or ventricular premature beats between tiotropium/olodaterol 5/5 µg combination therapy and its monocomponents. Compared with baseline, a small but statistically significant increase in adjusted mean heart rate was observed for tiotropium 5 µg (+1.6 beats per minute [bpm]; P=0.0010), but no difference was observed for olodaterol 5 µg (+0.3 bpm; P=0.2778) or tiotropium/olodaterol 5/5 µg (-0.1 bpm; P=0.4607). MACE and fatal MACE were limited to 1 to 3 patients across treatment groups. Conclusion Compared with the compounds given as monotherapy, treatment with tiotropium/olodaterol fixed-dose combination therapy is not associated with medically relevant or statistically significant effects on arrhythmia as assessed by Holter ECG. Based on these findings, there is no evidence to assume a clinically relevant impact on cardiac function from dual tiotropium/olodaterol treatment. Trial Registration TONADO 1 (ClinicalTrials.gov: NCT01431274); TONADO 2 (ClinicalTrials.gov: NCT01431287).

Correlation of Inhaled Long-Acting Bronchodilators With Adverse Cardiovascular Outcomes in Patients With Stable COPD: A Bayesian Network Meta-Analysis of Randomized Controlled Trials. J Cardiovasc Pharmacol 2020; 74:255-265. [PMID: 31306366 DOI: 10.1097/fjc.0000000000000705] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 12/28/2022]
Abstract
A majority of existing studies have focused on the efficacy of inhaled long-acting bronchodilators (ILABs), such as long-acting muscarinic antagonists (LAMAs) and long-acting β2-agonists (LABAs), and LABAs combined with LAMAs in treating chronic obstructive pulmonary disease (COPD). The current meta-analysis aimed to investigate the correlation of ILABs with specific cardiovascular adverse events (CAEs). Five electronic databases, including PubMed, Embase, Cochrane Library, Scopus, and Web of Science were systematically retrieved. Finally, 16 randomized controlled trials were enrolled into the current meta-analysis. Typically, the efficacy of 3 major classes of drugs (LABAs, LAMAs, and LABAs combined with LAMAs), and 7 specific drugs (including formoterol, glycopyrrolate, indacaterol, olodaterol, Salmeterol, tiotropium, and vilanterol) for 4 CAEs, including myocardial infarction, cardiac failure (CF), ischemic heart disease (IHD), and stroke in stable COPD patients, was examined. All the pooled results were analyzed through the odds ratios (ORs) with the corresponding 95% confidence intervals (CIs). The direct meta-analysis results suggested that LABAs could increase the risk of CF in patients with stable COPD compared with placebo controls (OR 1.70, 95% CI, 1.00-2.90). In addition, network meta-analysis results indicated that LAMAs combined with LABAs would result in an increased risk of CF in patients with stable COPD (OR 2.31, 95% CI, 1.10-5.09). According to the ILABs specific drug analysis, formoterol may potentially have protective effects on IHD compared with placebo controls (OR 0.45, 95% CI, 0.18-1.00). In conclusion, among these 3 kinds of ILABs, including LAMAs, LABAs, and LABAs/LAMAs, for stable COPD patients, LAMAs and LABAs are associated with the least possibility to induce myocardial infarction and stroke, respectively. However, the application of LABAs will probably increase the risk of CF; they should be used with caution for stable COPD patients with CF. In addition, in specific-drug analysis, the use of formoterol can reduce the risk of treatment-related IHD. Nevertheless, more studies on different drug doses are needed in the future to further validate this conclusion.

Relationship of inhaled long-acting bronchodilators with cardiovascular outcomes among patients with stable COPD: a meta-analysis and systematic review of 43 randomized trials. Int J Chron Obstruct Pulmon Dis 2019; 14:799-808. [PMID: 31114181 PMCID: PMC6489598 DOI: 10.2147/copd.s198288] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/14/2018] [Accepted: 02/22/2019] [Indexed: 12/28/2022] Open
Abstract
Background: Long-acting muscarinic antagonists (LAMAs) and long-acting β2–agonists (LABAs) are the mainstay of maintenance therapy for chronic obstructive pulmonary disease (COPD). Although previous studies have supported inhaled long-acting bronchodilators (ILABs) for overall cardiovascular safety, the risk of specific cardiovascular outcomes such as arrhythmia, heart failure and stroke is still unknown. Materials and methods: We systematically searched from PubMed, the Embase database and the Cochrane Library for published studies on ILABs and COPD, from its inception to November 10, 2018, with no language restrictions. The RRs and corresponding 95% CIs were pooled to evaluate ILAB/placebo. Results: Finally, 43 randomized controlled trials were included. Compared with placebo, ILABs do not increase the risk of overall and specific cardiovascular adverse events (AEs); on the contrary, they can reduce the incidence of hypertension (RR 0.73, 95% CI 0.55–0.98;I219.9%; P= 0.221). However, when stratified according to the specific agents of ILABs, olodaterol might reduce the risk of overall cardiovascular adverse events (OCAEs) (RR 0.65, 95% CI 0.49–0.88;I227.5%; P= 0.000), and the protective effect of lowing blood pressure disappeared. Similarly, the use of inhaled LABA might increase the risk of cardiac failure (RR 1.71, 95% CI 1.04–2.84;I20%; P= 0.538), but this risk disappeared when stratified according to the specific agents of LABA. Besides, formoterol might decrease the risk of cardiac ischemia (RR 0.53, 95% CI 0.32–0.91; I20%; P= 0.676). Conclusions: Overall, the use of ILABs was not associated with overall cardiovascular AEs in patients with stable COPD. When stratified according to the specific agents of LABA, olodaterol might reduce the risk of OCAE; and formoterol might decrease the risk of cardiac ischemia. LABA might reduce the incidence of hypertension, but might increase the risk of heart failure. Therefore, COPD patients with a history of heart failure should use it with caution.

The ethanol extract of Involcucrum castaneae ameliorated ovalbumin-induced airway inflammation and smooth muscle thickening in guinea pigs. JOURNAL OF ETHNOPHARMACOLOGY 2019; 230:9-19. [PMID: 30359762 DOI: 10.1016/j.jep.2018.10.027] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/28/2018] [Revised: 10/11/2018] [Accepted: 10/21/2018] [Indexed: 06/08/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Involucrum castaneae(IC)is used in Chinese folk medicine to treat various lung diseases, as well as for its reducing phlegm and anti-inflammatory properties. AIM OF THE STUDY The purpose of this experiment is to verify the effect of IC on airway inflammation, responsiveness in ovalbumin (OVA)-induced asthmatic guinea pigs. The main chemical components of IC were also analyzed. MATERIALS AND METHODS The potential of the ethanol extract of Involucrum castaneae (EEIC) to protect against OVA-induced allergic airway response in guinea pigs was investigated. The latency of asthma in guinea pigs were recorded after the allergic asthma induced. Enzyme-linked immunosorbent assay (ELISA) was used to measure the levels of immunoglobulin E (IgE), interleukin-5 (IL-5), nerve growth factor (NGF) and interferon-γ (IFN-γ) in asthma allergy. Reverse transcription-PCR (RT-PCR) was used to detect the expression of IL-5 mRNA in asthmatic guinea pig lungs. Paraffin sections of lung tissue were used to analyze pathological changes. The total flavonoid content was determined and the chemical components were analyzed by LC-MS/MS. RESULTS It was found that EEIC was able to reduce the number of eosinophil (EOS) in bronchoalveolar lavage fluid (BALF) and peripheral blood (PB) in the guinea pig model of OVA -induced asthma. Meanwhile, it also significantly reduced the levels of inflammation-related factors IgE and IL-5, decreased the expression of IL-5 mRNA in lung tissue, and increased the level of IFN-γ. Pathological examination of paraffin section of lung tissue showed that EEIC can reduce the thickening of bronchial smooth muscle and reduce the infiltration damage of tissues by various inflammatory cells. The presence of flavonoids, terpenoids and phenolic compounds in EEIC might be responsible for these activities. CONCLUSION IC alleviated airway inflammation and smooth muscle thickening in guinea pigs with OVA-sensitized allergic asthma. The paper explains the traditional efficacy and material basis of IC and lays a foundation for further development.

Abstract
BACKGROUND An extensive clinical trial program supports the efficacy and safety of tiotropium/olodaterol in chronic obstructive pulmonary disease (COPD). We examined the safety of tiotropium/olodaterol compared with tiotropium in a large population of patients, focusing on cardiovascular and respiratory events. METHODS Patients (n = 9942) who received once-daily tiotropium/olodaterol 5/5 μg or tiotropium 5 μg (via Respimat®) in TONADO 1 & 2 and DYNAGITO were included. The number of patients and exposure-adjusted rate of events are presented for adverse events (AEs), serious AEs (SAEs), AEs leading to discontinuation, and cardiovascular and respiratory events. FINDINGS Fewer patients discontinued due to AEs with tiotropium/olodaterol (5.9%) versus tiotropium (7.9%; rate ratio [RR] 0.72; 95% confidence interval [CI] 0.62-0.84). There was no significant difference in the incidence of AEs, SAEs, cardiovascular AEs or central nervous system vascular AEs between treatments. Incidences of major adverse cardiovascular events (MACE) were 2.11 per 100 patient-years with tiotropium/olodaterol and 2.22 with tiotropium (RR 0.95; 95% CI 0.72-1.25), and incidences of fatal MACE (including death with undetermined cause) were 0.91 and 1.00 per 100 patient-years with tiotropium/olodaterol and tiotropium, respectively (RR 0.91; 95% CI 0.60-1.37). Respiratory AEs were generally balanced between treatment groups. CONCLUSIONS These results provide robust evidence that the benefits of tiotropium/olodaterol versus tiotropium are not at the expense of an increased risk of safety events. The combination is a suitable option for patients with COPD, even in the presence of cardiovascular risk factors.

Int J Chron Obstruct Pulmon Dis 2018; 13:2147-2156. [PMID: 30034230 PMCID: PMC6049061 DOI: 10.2147/copd.s169941] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 01/01/2023] Open
Abstract
Background The DYNAGITO study was a Phase IIIb, randomized, double-blind, multicenter, active-controlled, parallel-group, 52-week study designed to determine the efficacy and safety of tiotropium and olodaterol combination therapy (TIO+OLO 5/5 μg) versus tiotropium monotherapy (TIO 5 μg) for reducing moderate-to-severe exacerbations of COPD. This is a prespecified analysis of the DYNAGITO data in Japanese patients. Patients and methods Enrolled patients had a diagnosis of COPD with at least one moderate-to-severe exacerbation in the previous 12 months. Of the total 7,880 treated patients in the DYNAGITO study, 461 (TIO+OLO 5/5 μg: n=226, TIO 5 μg: n=235) were Japanese. The primary endpoint was the annualized rate of moderate-to-severe COPD exacerbations. The key secondary endpoint was the time to first moderate-to-severe COPD exacerbation, and other secondary endpoints included the annualized rate of exacerbations leading to hospitalization, time to first COPD exacerbation leading to hospitalization, and all-cause mortality. Safety data were analyzed descriptively. Results Combination therapy with TIO+OLO resulted in a 29% lower rate of moderate-to-severe COPD exacerbations relative to TIO monotherapy (rate ratio 0.71; 99% CI: 0.46, 1.10; p=0.0434). The risk of a first moderate-to-severe COPD exacerbation was 19% lower with TIO+OLO combination therapy than with TIO monotherapy (HR 0.81; 99% CI: 0.57, 1.17; p=0.1379), although this difference was not statistically significant. The annualized rate of COPD exacerbations requiring hospitalization was 14% lower in the TIO+OLO arm than in the TIO arm (rate ratio 0.86; 95% CI: 0.52, 1.42; p=0.5654). The adverse event incidence was balanced between treatment arms. Conclusion In a prespecified subgroup analysis of Japanese patients in the DYNAGITO study, combination therapy with TIO+OLO was more effective than TIO in reducing exacerbations. Both treatments were well tolerated.
