The long-term efficacy and safety of formoterol dry powder capsules for inhalation in pediatric asthma have not previously been evaluated.
                We examined the effectiveness of inhaled formoterol over a period of 12 months in asthmatic children who were still symptomatic despite anti-inflammatory treatment.
                After a run-in period, 518 patients (5 to 12 years old) were randomized in a double-blind manner to receive 12 or 24 microg formoterol dry powder (Foradil, Novartis Pharma AG, Basel, Switzerland) or placebo twice daily for 12 months. The drug was administered by inhaler (Aerolizer, Novartis Pharma AG) and was given in addition to their anti-inflammatory treatment. The primary variable was the area under the curve for forced expiratory volume in 1 second measured over 12 hours after the morning dose of study medication.
                The area under the curve for forced expiratory volume in 1 second after the first dose of treatment and after 3 and 12 months of treatment was significantly greater for patients receiving formoterol 12 microg and 24 microg than for patients receiving placebo (all P < or = 0.0062). Compared with placebo, both doses of formoterol significantly improved morning and evening premedication peak expiratory flow rate (all P < 0.001). In the group treated with formoterol 24 microg, median symptom score and median dose of rescue medication at night were lower than during the run-in period, whereas the opposite occurred in the placebo group. The incidence of hospitalizations for asthma was higher in the formoterol groups than in the placebo group.
                Our results indicate that, in asthmatic children who are still symptomatic despite anti-inflammatory therapy, the addition of formoterol consistently improves airflow obstruction and nocturnal symptoms and reduces the use of rescue medication. However, this treatment requires close disease monitoring to detect early signs of acute exacerbation. This double-blind, placebo-controlled, randomized, parallel-group, multicenter study was conducted in 302 children aged 6-11 years with asthma not optimally treated with inhaled corticosteroids alone. Patients continued with their existing dose of inhaled corticosteroids and in addition received placebo, formoterol 4.5 microg or formoterol 9 microg b.i.d., for 12 weeks (all delivered via Turbuhaler). Terbutaline was available as reliever medication. The primary efficacy variable was change from baseline in morning peak expiratory flow (PEF); secondary efficacy variables included forced expiratory volume in 1 sec (FEV(1)), serial PEF measured over 12 hr, evening PEF, asthma symptom score, and quality of life. Compared with placebo, formoterol 4.5 microg and 9 microg improved morning PEF by 8 l/min (P = 0.035) and 11 l/min (P = 0.0045), respectively. Evening PEF and FEV(1) were also significantly increased compared with placebo, with no statistically significant difference between formoterol doses. Lung-function improvements compared with placebo were greater in the middle of the day. Twelve-hour average serial PEF after 3 months increased by 24 l/min (95% CI, 9, 39 l/min) in the formoterol 9-microg group, and by 14 l/min (95% CI, 0, 29 l/min) in the formoterol 4.5-microg group. The incidence of severe exacerbations in both formoterol groups was numerically lower than in the placebo group, indicating that formoterol may have the potential to improve exacerbation control in children. Both formoterol doses were well-tolerated, and tolerance to the drug's bronchodilator effect was not observed. Formoterol provided sustained improvements in lung function and was well-tolerated in children with asthma suboptimally treated with inhaled corticosteroids alone.
                Copyright 2004 Wiley-Liss, Inc. To determine the role of formoterol in the treatment of children with bronchial asthma who are symptomatic despite regular use of inhaled corticosteroids.
                A randomised, double blind, parallel group, placebo controlled study to investigate the effects of inhaled formoterol (12 microg twice a day) in 32 children with moderate to severe bronchial asthma. The study consisted of two week run in periods and six week treatment periods, during both of which the patients continued their regular anti-inflammatory drugs. The efficacy parameters were symptom scores, bronchodilator use, daily peak expiratory flow rates (PEFR), methacholine hyper-reactivity, forced expiratory volume in one second (FEV1), lung volumes, and airway conductance.
                Formoterol treatment for six weeks decreased symptom scores, PEFR variability, and the number of rescue salbutamol doses, and increased morning and evening PEFR significantly. No adverse reactions were seen.
                These findings suggest that inhaled formoterol is effective in controlling chronic asthma symptoms in children who are symptomatic despite regular use of inhaled corticosteroids. Previous studies have indicated the benefits of adding long acting beta(2) agonists to inhaled corticosteroids in the maintenance treatment of moderate to severe asthma. The effects of adding eformoterol to corticosteroids on asthma control and exacerbations in patients with mild to moderate asthma were studied.
                After a run in period of 7-14 days on existing medication, 663 symptomatic patients were randomised to receive budesonide Turbohaler 400 microg twice daily together with either eformoterol Turbohaler 9 micro g (delivered dose) or placebo twice daily. After 4 weeks patients whose asthma was well controlled (n=505) were re-randomised to receive budesonide 400 microg daily and either eformoterol 9 micro g or placebo twice daily for a further 6 months.
                Patients receiving eformoterol achieved asthma control 10 days sooner than those receiving budesonide alone, and improvements in lung function, symptoms, quality of life, and relief beta(2) agonist use were significantly greater with eformoterol. During the 6 month follow up the frequency of mild exacerbations was significantly lower in the eformoterol group than in those receiving budesonide alone (7.2 versus 10.5 per patient, 95% confidence interval for ratio 0.49 to 0.96, p=0.03). The time to first day of poorly controlled asthma was 97 days in the eformoterol group compared with 42 days in the placebo group (p=0.003).
                Adding eformoterol to a low or moderate dose of budesonide in mild asthma resulted in faster and more effective control than treatment with budesonide alone. Eformoterol allowed the corticosteroid dose to be reduced while also decreasing the rate of mild exacerbations compared with budesonide alone. These data suggest a therapeutic advantage of adding eformoterol to inhaled corticosteroids in patients with mild to moderate asthma. Formoterol is a beta2-adrenergic agent which, when inhaled, produces rapid and long-lasting bronchodilatation.
                The aim of this study was to compare the efficacy, safety, and tolerability of formoterol powder for inhalation delivered via the Aerolizer device with placebo and with albuterol delivered via metered-dose inhaler in patients with mild to moderate persistent asthma.
                In a multicenter, double-blind, parallel-group study, 541 patients were randomized at 26 trial sites to receive either formoterol, 12 microg twice daily; formoterol, 24 microg twice daily; albuterol, 180 microg four times daily; or a placebo for 12 weeks. The effects of each treatment on lung function, asthma symptoms, and frequency of rescue albuterol use were evaluated. Adverse effects and clinical laboratory parameters were also evaluated.
                The bronchodilatory effects of formoterol were rapid in onset and persisted for 12 hours. Both formoterol doses were more effective than placebo and albuterol for objective measures of lung function. Morning and evening peak expiratory flow rates were more improved with formoterol, and formoterol provided significantly greater improvements in asthma symptom scores compared with both albuterol and placebo. Overall, patients taking formoterol used significantly less rescue medication than did those taking albuterol or placebo. Nocturnal awakenings occurred less often with formoterol than with placebo or albuterol. The therapeutic effects of formoterol were maintained over the entire 12 weeks of treatment. Adverse events were similar for all treatment groups, and clinical laboratory data were unremarkable.
                Rapid-onset, long-acting formoterol, administered via the Aerolizer inhaler, is an effective and safe treatment for patients with mild to moderate persistent asthma. The primary objective was to determine whether high-dose formoterol, 24 mug bid, was associated with more asthma exacerbations compared with lower formoterol doses in patients with stable persistent asthma. Serious asthma exacerbations (life threatening or requiring hospitalization) were the primary end point. Secondary end points included significant exacerbations requiring systemic corticosteroids, all exacerbations, and changes in FEV1.
                In a multicenter, placebo-controlled, parallel-group study, patients were randomized to 16 weeks of treatment with formoterol, 24 microg bid; formoterol, 12 microg bid, with up to two additional 12-microg doses daily on demand for worsening symptoms (12 microg bid plus on demand); formoterol, 12 microg bid; or placebo. The formoterol 12-microg-bid plus on-demand regimen was administered open label, while the other three regimens were double blind.
                Outpatient clinics.
                A total of 2,085 patients aged > or = 12 years with stable, persistent asthma were enrolled and treated; 65% (n = 1,347) received regular concomitant antiinflammatory therapy during the study.
                Nine patients had respiratory-related serious adverse events (SAEs) requiring hospitalization: two patients (0.4%) in the 24-microg-bid group; one patient (0.2%) in the 12-microg-bid plus on-demand group; five patients (0.9%) in the 12-microg-bid group; and one patient (0.2%) in the placebo group. All of these events were asthma related, except for two SAEs in the 12-microg-bid group that were later considered not to be asthma related by independent reviewers who were not associated with the conduct of the study. The proportions of patients with significant asthma exacerbations (requiring systemic corticosteroids) were similar in the 24-microg-bid group (6.3%, 33 of 527 patients), 12-microg-bid group (5.9%, 31 of 527 patients) and placebo group (8.8%, 45 of 514 patients) and lower in the 12-microg-bid plus on-demand group (4.4%, 23 of 517 patients; p = 0.0057 vs placebo). All treatments were well tolerated. All formoterol treatment regimens had a significant effect on FEV1 measured 2 h after dose during the study (p < 0.0001 vs placebo); and on predose trough FEV1 measured at all visits after baseline (p < 0.002 vs placebo).
                Treatment with formoterol, 24 microg bid, was not associated with an increase in serious asthma exacerbations compared with the lower formoterol doses or placebo. Our objective was to compare the efficacy and safety of formoterol (Foradil) delivered via a novel multidose dry powder inhaler (Certihaler) with placebo and albuterol [pressurized metered-dose inhaler (pMDI)], in patients with persistent asthma. After a 2-week run-in phase, 265 patients (13-81 years) previously treated with regular/PRN bronchodilators for persistent asthma were randomized to 12 weeks' double-blind treatment with formoterol 10 microg BID via Certihaler (n = 86), albuterol 180 microg QID via pMDI (n = 88) or placebo (n = 91). The primary efficacy variable was 12-hour AUC of FEV1 after 12 weeks' treatment. Secondary efficacy variables included peak expiratory flow (PEF), rescue bronchodilator medication use, asthma-related quality of life (Juniper Mini Asthma Quality of Life Questionnaire), and asthma symptom scores. Formoterol via the Certihaler had an onset of action within 5 minutes and was associated with a clinically relevant and statistically significant increase in 12-hour AUC of FEV1 after 12 weeks' treatment compared with placebo and albuterol (p < 0.001 and p < 0.05, respectively). Average PEF was significantly superior for formoterol compared with placebo and albuterol (p < 0.001 and p < 0.05, respectively). Compared with placebo, rescue albuterol use during the study was significantly lower for formoterol (p < 0.01) and was accompanied by a trend toward an improvement in asthma-related quality of life (QoL). Asthma symptom scores improved to a similar extent for all treatment groups. Treatment with formoterol via Certihaler was well tolerated. Formoterol 10 microg BID, delivered via the novel Certihaler device, is well tolerated and provides rapid, long-lasting, and clinically superior bronchodilation to placebo and albuterol via pMDI in patients with persistent asthma. The role of long-acting, inhaled beta2-agonists in treating asthma is uncertain. In a double-blind study, we evaluated the effects of adding inhaled formoterol to both lower and higher doses of the inhaled glucocorticoid budesonide.
                After a four-week run-in period of treatment with budesonide (800 microg twice daily), 852 patients being treated with glucocorticoids were randomly assigned to one of four treatments given twice daily by means of a dry-powder inhaler (Turbuhaler): 100 microg of budesonide plus placebo, 100 microg of budesonide plus 12 microg of formoterol, 400 microg of budesonide plus placebo, or 400 microg of budesonide plus 12 microg of formoterol. Terbutaline was permitted as needed. Treatment continued for one year; we compared the frequency of exacerbations of asthma, symptoms, and lung function in the four groups. A severe exacerbation was defined by the need for oral glucocorticoids or a decrease in the peak flow to more than 30 percent below the base-line value on two consecutive days.
                The rates of severe and mild exacerbations were reduced by 26 percent and 40 percent, respectively, when formoterol was added to the lower dose of budesonide. The higher dose of budesonide alone reduced the rates of severe and mild exacerbations by 49 percent and 37 percent, respectively. Patients treated with formoterol and the higher dose of budesonide had the greatest reductions -- 63 percent and 62 percent, respectively. Symptoms of asthma and lung function improved with both formoterol and the higher dose of budesonide, but the improvements with formoterol were greater.
                In patients who have persistent symptoms of asthma despite treatment with inhaled glucocorticoids, the addition of formoterol to budesonide therapy or the use of a higher dose of budesonide may be beneficial. The addition of formoterol to budesonide therapy improves symptoms and lung function without lessening the control of asthma. We aimed to compare the efficacy and safety of budesonide/formoterol (Symbicort) with budesonide alone (Pulmicort) or budesonide (Pulmicort) and formoterol (Oxis) administered via separate inhalers in children with asthma. In a 12 wk, double-blind study, a total of 630 children with asthma (mean age 8 yr [4-11 yr]; mean forced expiratory volume in 1 s (FEV(1)) 92% predicted; mean inhaled corticosteroid dose 454 microg/day) were randomized to: budesonide/formoterol (80/4.5 microg, two inhalations twice daily); a corresponding dose of budesonide alone (100 microg, two inhalations twice daily); or a corresponding dose of budesonide (100 microg, two inhalations twice daily) and formoterol (4.5 microg, two inhalations twice daily) (budesonide + formoterol in separate inhalers). The primary efficacy variable was the change from baseline to treatment (average of the 12-wk treatment period) in morning peak expiratory flow (PEF). Other changes in lung function and asthma symptoms were assessed, as was safety. Budesonide/formoterol significantly improved morning PEF, evening PEF and FEV(1) compared with budesonide (all p < 0.001); there was no significant difference between budesonide/formoterol and budesonide + formoterol in separate inhalers for these variables. All other diary card variables improved from baseline in all treatment groups; there were no significant between-group differences. Adverse-event profiles were similar in all groups; there were no serious asthma-related adverse events in any treatment group. Conclusion: budesonide/formoterol significantly improved lung function in children (aged 4-11 yr) with asthma compared with budesonide alone. Budesonide/formoterol is a safe and effective treatment option for children with asthma.
In comparison with placebo, we have found an increased risk of serious adverse events with regular formoterol, and this does not appear to be abolished in patients taking inhaled corticosteroids. The effect on serious adverse events of regular formoterol in children was greater than the effect in adults, but the difference between age groups was not significant.
Data on all-cause serious adverse events should be more fully reported in journal articles, and not combined with all severities of adverse events or limited to those events that are thought by the investigator to be drug-related.
