A non-interventional switch study in adult patients with asthma or COPD on clinical effectiveness of salmeterol/fluticasone Easyhaler^® in routine clinical practice.

ABSTRACT:

Background

Selection of the most appropriate device for a switch from one inhaler to an equivalent product is known to have a major impact on clinical outcomes in patients with asthma or chronic obstructive pulmonary disease (COPD). Salmeterol/fluticasone propionate (S/F) Easyhaler^® has been demonstrated to be therapeutically equivalent with a reference product. However, no data on real-life effectiveness are currently available for patients switching to S/F Easyhaler from another S/F inhaler.

Methods

The aim of this prospective, open, multicenter, non-interventional study was to assess clinical effectiveness of propionate S/F Easyhaler in adult asthma and COPD patients switched from another inhaler. The primary endpoints were Asthma Control Test (ACT) and COPD Assessment Test (CAT). Secondary endpoints included assessments of patient satisfaction and preference and physician/nurse perception on S/F Easyhaler use. The study included three visits during a 12-week follow-up.

Results

A total of 211 patients (160 with asthma; 51 with COPD) were included in the analyses. In patients with asthma, there was a statistically significant increase in the mean ACT score at week 12 (20.2 ± 3.9) compared with the baseline (18.6 ± 4.1), with a mean increase of 1.6 (±3.5) points (p < 0.0001). In patients with COPD, CAT score persisted from baseline (19.9 ± 8.6) to week 12 (19.6 ± 7.0). Patients were significantly more satisfied with Easyhaler and most patients preferred Easyhaler over their previous inhaler. The physicians/nurses reported that it was 'very easy' to teach the use of Easyhaler and the training took less than 5 minutes in most cases.

Conclusion

The results from this prospective real-life clinical study indicate better or at least similar treatment control of asthma and COPD after switching to S/F Easyhaler from another S/F inhaler. This study also shows that S/F Easyhaler was favored by the patients and that it is easy to teach, learn and use in a real-life setting.The reviews of this paper are available via the supplemental material section.

Project description:BACKGROUND:Easyhaler® dry powder inhaler (DPI) containing salmeterol and fluticasone propionate was developed for the treatment of asthma and chronic obstructive pulmonary disease. Three different Salmeterol/fluticasone Easyhaler test products (Orion Pharma, Finland) were compared against the reference product Seretide® Diskus® DPI (GlaxoSmithKline, United Kingdom) to study whether any of the test products are bioequivalent with the reference. METHODS:Open and randomized pharmacokinetic four-period crossover study on 65 healthy volunteers was performed in a single center to compare the lung deposition and total systemic exposure of salmeterol and fluticasone propionate after administration of single doses (two inhalations of 50/500??g/inhalation strength) in fasting conditions. Blood samples were drawn before dosing and at frequent time points between 2 minutes and 34 hours after dosing for determination of drug concentrations. The primary variables for total systemic exposure and lung deposition of fluticasone propionate were maximum concentration of the concentration-time curve (Cmax) and area under the concentration-time curve from time zero to the last sample with quantifiable concentration (AUCt). For salmeterol, the primary variables for total systemic exposure were Cmax and AUCt and for lung deposition Cmax and AUC up to 30 minutes after study treatment administration (AUC30min). RESULTS:One of the Easyhaler test products met all the criteria for bioequivalence with the reference. The 96.7% confidence intervals (CIs) for the test/reference ratios of fluticasone propionate Cmax and AUCt were 0.9901-1.1336 and 0.9448-1.0542, respectively. Ninety percent CIs for salmeterol Cmax, AUC30min, and AUCt ratios were 1.0567-1.2012, 1.0989-1.2255, and 1.0769-1.1829, respectively. Median salmeterol time to maximum concentration (tmax) was 4.0 minutes. Median fluticasone propionate tmax was from 1.5 to 2.0 hours. Terminal elimination half-life was 11 hours for salmeterol and 9-10 hours for fluticasone propionate. CONCLUSIONS:Salmeterol/fluticasone Easyhaler was shown to be bioequivalent with the reference product.

Project description:BackgroundThe current Global initiative for chronic Obstructive Lung Disease (GOLD) treatment strategy recommends the use of one or more bronchodilators according to the patient's airflow limitation, their history of exacerbations, and symptoms. The LANTERN study evaluated the effect of the long-acting β2-agonist (LABA)/long-acting muscarinic antagonist (LAMA) dual bronchodilator, QVA149 (indacaterol/glycopyrronium), as compared with the LABA/inhaled corticosteroid, salmeterol/fluticasone (SFC), in patients with moderate-to-severe COPD with a history of ≤1 exacerbation in the previous year.MethodsIn this double-blind, double-dummy, parallel-group study, 744 patients with moderate-to-severe COPD with a history of ≤1 exacerbations in the previous year were randomized (1:1) to QVA149 110/50 μg once daily or SFC 50/500 μg twice daily for 26 weeks. The primary endpoint was noninferiority of QVA149 versus SFC for trough forced expiratory volume in 1 second (FEV1) at week 26.ResultsOverall, 676 patients completed the study. The primary objective of noninferiority between QVA149 and SFC in trough FEV1 at week 26 was met. QVA149 demonstrated statistically significant superiority to SFC for trough FEV1 (treatment difference [Δ]=75 mL; P<0.001). QVA149 demonstrated a statistically significant improvement in standardized area under the curve (AUC) from 0 hours to 4 hours for FEV1 (FEV1 AUC0-4h) at week 26 versus SFC (Δ=122 mL; P<0.001). QVA149 and SFC had similar improvements in transition dyspnea index focal score, St George Respiratory Questionnaire total score, and rescue medication use. However, QVA149 significantly reduced the rate of moderate or severe exacerbations by 31% (P=0.048) over SFC. Overall, the incidence of adverse events was comparable between QVA149 (40.1%) and SFC (47.4%). The incidence of pneumonia was threefold lower with QVA149 (0.8%) versus SFC (2.7%).ConclusionThese findings support the use of the LABA/LAMA, QVA149 as an alternative treatment, over LABA/inhaled corticosteroid, in the management of moderate-to-severe COPD patients (GOLD B and GOLD D) with a history of ≤1 exacerbation in the previous year.

Project description:BackgroundInhalation therapy with corticosteroids and long-acting β2-agonists has been the mainstay of asthma management. However, choosing the correct inhaler technique is essential to effectively deliver the medication to the lungs to attain good asthma control.ObjectiveThis study aimed to evaluate asthma control and device usability with salmeterol/fluticasone fixed-dose combination (FDC) administered through Synchrobreathe®, a breath-actuated inhaler (BAI), in Indian patients with persistent asthma (EVOLVE study).DesignThe present study was a prospective, open-label, non-comparative, multi-center, observational study.MethodsThe study enrolled 490 patients with documented diagnoses of asthma who were treatment-naive or uncontrolled due to poor inhaler technique associated with a previous device. The primary endpoint was a change from baseline in the Asthma Control Questionnaire-6 (ACQ-6) score at week 12.ResultsMean ACQ-6 score reduced from 2.2 ± 1.07 (baseline) to 0.4 ± 0.49 (mean change: -1.9 ± 1.12, p < 0.0001) at week 12 in the intention-to-treat (ITT) population, and minimal clinically important difference of 0.5 was observed from week 4 onwards. Peak expiratory flow rate improved by 82.5 ± 75.74 ml/min (p < 0.0001) at week 12 in the ITT population. The proportion of well-controlled responders increased from 39.9% (week 4) to 77.1% (week 12). Most (91%) patients preferred the Synchrobreathe® and rated it very high for usability, portability, patient confidence, and satisfaction. Salmeterol/fluticasone FDC administered through Synchrobreathe® was well tolerated.ConclusionTreatment with salmeterol/fluticasone FDC administered through Synchrobreathe® for 12 weeks persistently improved asthma control and lung function and was well tolerated. Most patients were satisfied with it and preferred Synchrobreathe® BAI over their previous device.RegistrationThe study was registered with the Clinical Trial Registry of India (CTRI/2018/12/016629).
