Indacaterol vs tiotropium in COPD patients classified as GOLD A and B
2015
SummaryIntroductionAccording to current GOLD strategy, patients with COPD classified as groups A and B may be treated with inhaled bronchodilators, either long-acting β2-agonist (LABA) or long-acting muscarinic antagonist (LAMA). However, there is little guidance on which class of agent is preferred and a lack of prospective data to differentiate the two.MethodsIn this study, we performed post-hoc analyses of pooled data from two prospective, controlled clinical trials comparing the LABA indacaterol and LAMA tiotropium in 1422 patients with moderate airflow limitation and no history of exacerbations in the previous year. This population fits the definitions of GOLD A and B groups and could …
High-resolution computed tomography quantitation of emphysema is correlated with selected lung function values in stable COPD
2012
<b><i>Background:</i></b> The literature shows conflicting results when high-resolution computed tomography (HRCT) scores of emphysema were correlated with different indices of airflow obstruction. <b><i>Objectives:</i></b> We correlated HRCT scores of emphysema with different indices of airflow obstruction. <b><i>Methods:</i></b> We performed HRCT of the chest in 59 patients, all smokers or ex-smokers, with stable chronic obstructive pulmonary disease of different severity [GOLD stages I–IV; mean age ± SD 67.8 ± 7.3 years; pack/years 51.0 ± 34.6; percent predicted forced expiratory volume in 1 s (FEV<sub>1</su…
Efficacy and safety of once-daily QVA149 compared with the free combination of once-daily tiotropium plus twice-daily formoterol in patients with mod…
2015
Background QVA149 is a once-daily (o.d.) inhaled dual bronchodilator containing a fixed-dose combination of the long-acting β2-agonist indacaterol and the long-acting muscarinic antagonist glycopyrronium for the treatment of COPD. The QUANTIFY study compared QVA149 with a free-dose bronchodilator combination of tiotropium plus formoterol (TIO+FOR) in improving health-related quality of life (HRQoL) of patients with COPD. Methods This multicentre, blinded, triple-dummy, parallel-group, non-inferiority study randomised patients aged ≥40 years with moderate-to-severe COPD (post-bronchodilator forced expiratory volume in 1 s (FEV1) ≥30% to <80% predicted) to QVA149 110/50 µg o.d. or TIO 18 µg o…
Oral Sustained-Release Aminophylline and Bronchodilator Response to Inhaled Fenoterol in Patients with Chronic Airflow Obstruction
1985
The bronchodilator response to inhaled fenoterol (400 micrograms) was examined in the morning and in the afternoon before and during oral sustained-release aminophylline treatment in eight patients with chronic reversible airway obstruction. Bronchodilatation was evaluated by measuring serial peak expiratory flow rates (PEFR) for eight hours after inhaled fenoterol and calculating the area under the time-response curves and the percentage increment from the baseline values. The patients showed an enhancement of the bronchodilatation achieved with fenoterol in the morning during aminophylline treatment. In the afternoon, instead, the effect of the fenoterol was not improved by oral aminophyl…
Additive Effects of Salmeterol and Fluticasone or Theophylline in COPD
2000
ss(2)-Agonists and corticosteroids or theophylline can interact to produce beneficial effects on airway function in asthma, but this has not been established in COPD.Eighty patients with well-controlled COPD were randomized to receive 3 months of treatment in one of four treatment groups: (1) salmeterol, 50 microg bid; (2) salmeterol, 50 microg, plus fluticasone propionate, 250 microg bid; (3) salmeterol, 50 microg, plus fluticasone propionate, 500 microg bid; and (4) salmeterol, 50 microg, plus titrated theophylline bid. At each visit, a dose-response curve to inhaled salbutamol was constructed using a total cumulative dose of 800 microg.A gradual increase in FEV(1) was observed with each …
Indacaterol once-daily provides superior efficacy to salmeterol twice-daily in COPD: A 12-week study
2011
SummaryBackgroundIndacaterol is a novel, inhaled once-daily ultra-long-acting β2-agonist for the treatment of COPD.MethodsThis 12-week randomised, parallel-group study compared the efficacy of indacaterol 150 μg once-daily to salmeterol 50 μg twice-daily in patients with moderate-to-severe COPD. Assessments included FEV1 standardised area under curve (AUC) from 5 min to 11 h 45 min at Week 12 (primary endpoint), 24-h trough FEV1 (mean of 23 h 10 min and 23 h 45 min post-dose) at Week 12 (key secondary endpoint), FEV1 and FVC measured over 24-h, transition dyspnoea index (TDI) and rescue medication use.ResultsOf 1123 patients randomised 92.1% completed. Mean ± SD age was 62.8 ± 8.78 years, p…
Pooled safety analysis of the fixed-dose combination of indacaterol and glycopyrronium (QVA149), its monocomponents, and tiotropium versus placebo in…
2014
BACKGROUND: To further assess the safety profile of the fixed-dose combination of indacaterol and glycopyrronium (QVA149) and its monocomponents; we investigated the impact of individual patient-level factors and time by integrating the patient-level safety data from the QVA149 clinical programme with relevant information from the independent indacaterol and glycopyrronium safety databases.METHODS: Data from 11,404 patients with chronic obstructive pulmonary disease (COPD) were pooled from 14 clinical studies of QVA149, indacaterol and glycopyrronium of ≥3 month's duration with at least two of the treatment groups: QVA149 110/50 μg, glycopyrronium 50 μg, indacaterol 150 μg, placebo or tiotr…
Long-term general and cardiovascular safety of tiotropium/olodaterol in patients with moderate to very severe chronic obstructive pulmonary disease
2016
Abstract Background Long-term safety, particularly cardiovascular safety, is of special interest in maintenance treatment of chronic obstructive pulmonary disease (COPD) with long-acting β 2 -agonists and long-acting muscarinic antagonists, given potential cardiovascular effects. Methods Two 52-week Phase III trials (TONADO ® ) investigated tiotropium/olodaterol (5/5 and 2.5/5 μg) versus tiotropium 2.5, 5 μg and olodaterol 5 μg. In a pre-specified safety analysis, investigator-reported treatment-emergent adverse events (AEs), electrocardiogram and laboratory data were pooled. All serious AE (SAE) reports were reviewed by an independent Adjudication Committee, which assessed whether deaths, …
Multicentric study on the beta-blocker use and relation with exacerbations in COPD
2014
SummaryChronic obstructive pulmonary disease (COPD) is frequently associated with chronic heart failure (CHF) or coronary artery disease (CAD). In spite of the recommendation to use beta-blockers (BB) they are likely under-prescribed to patients with concurrent COPD and heart diseases. To find out the prevalence of use of BB, 256 COPD patients were consecutively recruited by pulmonary physicians from 14 hospitals in 7 regions of Spain in their outpatient offices if they had a diagnosis of COPD, were not on long-term oxygen therapy, had CHF or CAD, and met the criteria for BB treatment.In patients with indication 58% (95%CI, 52–64%) of the COPD patients and 97% of the non-COPD patients were …
Pharmacological treatment of patients with chronic critical limb ischemia: L-propionyl-carnitine enhances the short-term effects of PGE-1.
2009
Purpose. To evaluate the therapeutic effects of L-propionyl-carnitine (LPC) in patients with critical limb ischemia (CLI), as defined by the TASC guidelines. Methods. The study, double-blinded, randomised, assessed intravenous infusion of LPC 1.2 g/day in combination with PGE-1, 60 mg/day (LPC group: 37 patients), or PGE-1 only (control group: 38 patients) in a total of 75 patients suffering from CLI. Treatment duration was 20 days. We evaluated rest pain, maximum walking distance (MWD) and skin ulcer size. Results. In both groups we observed a significant reduction in pain score and ulcer size and an increase in MWD. In the patients treated with the combination, the improvement was greater…
