Salbutamol 200microgram / Beclometasone 100microgram inhalation powder capsules

BackgroundAccording to international treatment guidelines, inhaled rapid-acting β2 agonists should be used for the control of symptoms in patients with asthma. We compared the efficacy and safety of an extrafine combination inhaler containing a corticosteroid (beclometasone) plus a rapid-onset, long-acting β2 agonist (formoterol) with a short-acting β2 agonist (salbutamol) as reliever strategies in patients taking beclometasone-formoterol combination as maintenance treatment.MethodsIn a double-blind trial undertaken in 183 centres in 14 European countries over 48 weeks, patients (aged ≥18 years) with asthma that was not fully controlled, with a forced expiratory volume in 1 s (FEV1) of at least 60% predicted, had a 2-week run in. During this period, patients were treated with a combination of beclometasone 100 μg and formoterol 6 μg per one inhalation twice daily plus salbutamol 100 μg as required delivered by use of a pressurised metered-dose inhaler. They were then randomly assigned in a 1:1 ratio with a computer-generated randomisation list to receive beclometasone 100 μg plus formoterol 6 μg or salbutamol 100 μg as reliever in addition to maintenance with beclometasone 100 μg plus formoterol 6 μg twice daily. Primary outcome was the time to first severe exacerbation (admission to hospital or visit to emergency department, or use of systemic steroids for ≥3 consecutive days). Secondary outcomes were number of severe exacerbations (events per 100 patients per year), time to and number of mild exacerbations, additional exacerbation variables, lung function, symptom scores, and asthma control. Analysis was by intention to treat. The study is registered with ClinicalTrials.gov, number NCT00861926.Findings1714 patients were randomly assigned to the as-needed beclometasone-formoterol (n=857) and as-needed salbutamol groups (n=857), and 1701 were analysed (852 and 849, respectively). 326 severe exacerbations were reported by 251 patients during the study, and 99 versus 152 patients had at least one exacerbation during the 48 weeks, respectively. Compared with beclometasone-formoterol plus salbutamol as needed, beclometasone-formoterol for both maintenance and reliever treatment significantly increased the time to first exacerbation (209 days vs 134 days) by 75 days, with a 36% reduction in risk (hazard ratio 0·64 [95% CI 0·49 to 0·82]; p=0·0005), and the estimated probability was 12% and 18%, respectively (p=0·0003). The number of days with mild asthma exacerbations was also lower with as-needed beclometasone-formoterol than with as-needed salbutamol (56·04 days per patient per year vs 65·11 days per patient per year; 0·86 [0·76 to 0·98]; p=0·021). From the run-in period to week 48, both treatments improved symptoms (mean change -1·59 [-1·94 to -1·25] in the as-needed beclometasone-formoterol group vs -1·44 [-1·78 to -1·10] in the as-needed salbutamol group, difference -0·15 [-0·60 to 0·30]; p=0·507), percentage of asthma control days (9·5% [7·3 to 11·8] vs 10·9% [8·7 to 13·1], respectively, -1·4 [-4·3 to 1·6]; p=0·359), use of reliever (-0·29 [-0·38 to -0·20] vs -0·27 [-0·36 to -0·19], respectively, -0·02 [-0·13 to 0·10]; p=0·794), and lung function (FEV1, 0·090 [0·060 to 0·120] vs 0·090 [0·060-0·120], respectively, 0·001 [-0·040 to 0·040]; p=0·969), and were well tolerated (patients with serious adverse events, 32 [4%] and 41 [5%], respectively).InterpretationOur results lend support to the use of the combination of a single inhaled corticosteroid plus a rapid-onset, long-acting β2 agonist for maintenance and relief in patients with moderate to severe asthma and provide encouraging data for the formulation of beclometasone-formoterol for this use.FundingChiesi Farmaceutici.

BackgroundAsthma demonstrates a robust daily rhythm, with airflow obstruction and airway inflammation peaking overnight. Aligning the timing of drug administration with rhythms in disease (chronotherapy) may improve therapeutic efficacy. We aimed to evaluate the impact of dosage timing for inhaled corticosteroids in asthma.MethodsThis is a randomised three-way crossover trial. Participants with mild to moderate atopic asthma were randomised to beclometasone dipropionate: (1) 400 µg once daily between 08:00 and 09:00 (ODAM); (2) 400 µg once daily between 15:00 and 16:00 (ODPM); and (3) 200 µg twice daily between 08:00 and 09:00 and between 20:00 and 21:00 (BD) for 28 days, with a 2 week washout period in between treatment periods. Six-hourly spirometry and biomarkers were measured over 24 hours following the run-in period and at the end of each treatment period.ResultsOf 25 participants, 21 completed all regimens. ODPM was superior in improving 22:00 FEV1 (median (IQR): +160 (+70, +270) ml) compared with ODAM (-20 (-80, +230) ml) and BD (+80 (-20, +200) ml). ODPM resulted in better overnight (22:00 and 04:00) suppression in blood eosinophil counts compared with BD and ODAM. All regimens improved asthma control and reduced fractional exhaled nitric oxide and serum cortisol levels with no difference among dosing regimens.ConclusionODPM better suppresses the nocturnal dip in lung function and peak of blood eosinophil counts compared with BD and ODAM; this was without an increase in adverse events. Future trials are warranted to validate these findings in real-life settings and to determine which population may best benefit from chronotherapy.

BackgroundThe single-inhaler triple combination of beclometasone dipropionate, formoterol fumarate, and glycopyrronium (BDP/FF/G) is available for maintenance therapy of chronic obstructive pulmonary disease (COPD). Cardinal features of COPD are lung hyperinflation and reduced exercise capacity. TRIFORCE aimed to evaluate the effect of BDP/FF/G on lung hyperinflation and exercise capacity in patients with COPD.MethodsThis double-blind, randomised, active- and placebo-controlled, crossover study recruited adults with COPD aged ≥ 40 years, who were hyperinflated and symptomatic, and were receiving mono- or dual inhaled maintenance COPD therapy. In the three treatment periods, patients were randomised to receive BDP/FF/G, BDP/FF, or placebo, each for 3 weeks, with a 7-10-day washout between treatment periods. Assessments included slow inspiratory spirometry (for resting inspiratory capacity [IC]) and constant work-rate cycle ergometry (for dynamic IC and exercise endurance time). The primary objective was to compare BDP/FF/G and BDP/FF vs. placebo for resting IC at Week 3. Key secondary objectives were to compare BDP/FF/G and BDP/FF vs. placebo for dynamic IC and exercise endurance time during constant work rate cycle ergometry at Week 3.ResultsOf 106 patients randomised, 95 completed the study. Resting IC adjusted mean differences vs. placebo were 315 and 223 mL for BDP/FF/G and BDP/FF, respectively (p ConclusionsIn patients with COPD, BDP/FF/G provided significant and clinically relevant improvements vs. placebo and BDP/FF in static and dynamic hyperinflation, with an improvement vs. placebo in exercise endurance.Trial registrationClinicalTrials.gov (NCT05097014), registered 27th October 2021.

BackgroundA single-inhaler extrafine triple combination of beclometasone dipropionate (BDP), formoterol fumarate (FF) and glycopyrronium (G) has been developed for maintenance therapy of chronic obstructive pulmonary disease (COPD). This study evaluated the efficacy and safety of BDP/FF/G in patients in three eastern Asian areas: China, Republic of Korea and Taiwan.MethodsTRIVERSYTI was a double-blind, randomised, active-controlled, parallel-group study in patients with COPD, post-bronchodilator forced expiratory volume in 1 s (FEV1) 1 at Week 24 (these were analysed as key secondary objectives in the China subgroup). The rate of moderate/severe COPD exacerbations was a secondary endpoint.ResultsOf 708 patients randomised, 88.8% completed. BDP/FF/G was superior to BUD/FF for pre-dose and 2-h post-dose FEV1 at Week 24 [adjusted mean differences 62 (95% CI 38, 85) mL and 113 (87, 140) mL; both p ConclusionsIn patients with COPD, FEV1 < 50% and an exacerbation history despite maintenance therapy, treatment with extrafine BDP/FF/G improved bronchodilation, and was more effective at preventing moderate/severe COPD exacerbations than BUD/FF.
