RESUMO
OBJECTIVES: Asthma affects over 6 million children in the United States alone. This study investigated the efficacy and long-term safety of mometasone furoate-formoterol (MF/F) and MF monotherapy in children with asthma. MATERIALS AND METHODS: This phase 3, multicenter, randomized controlled trial evaluated metered-dose inhaler twice daily (BID) dosing with MF/F 100/10 µg or MF 100 µg in children, aged 5 to 11 years, with a history of asthma for greater than or equal to 6 months and confirmed bronchodilator reversibility, who were adequately controlled on inhaled corticosteroid/long-acting beta-agonist combination therapy for greater than or equal to 4 weeks. After a 2-week run-in on MF 100 µg BID, eligible patients received 24 weeks of double-blind treatment and were followed for safety up to 26 weeks. The primary efficacy endpoint was the change from baseline in AM postdose 60-minute AUC %predicted FEV1% across 12 weeks of treatment. RESULTS: A total of 181 participants received at least one dose of MF/F (n = 91) or MF (n = 90). MF/F was superior to MF across the 12-week evaluation period, with a treatment advantage of 5.21 percentage points (P < .001). Superior onset of action with MF/F over MF was achieved as early as 5 minutes postdose on day 1. Overall, approximately 50% of participants experienced one or more treatment-emergent adverse events, with fewer occurring in the MF/F group. CONCLUSIONS: In children 5 to 11 years of age with persistent asthma, the addition of F to MF was well tolerated and provided significant, rapid, and sustained improvement in lung function compared with MF alone.

OBJECTIVES: A fixed combination of long-acting beta(2)-agonists (LABA) plus inhaled corticosteroids (ICS) has never been proven to reduce asthma exacerbations vs ICS alone in children. This 12-month, double-blind, randomized study in 341 children (age range, 4 to 11 years) with asthma uncontrolled on ICS investigated whether a novel regimen using budesonide/formoterol for maintenance and reliever therapy (Symbicort maintenance and relief therapy [SMART]) [Symbicort; AstraZeneca R&D, Lund, Sweden] could reduce exacerbations. METHODS: Patients received SMART (budesonide/formoterol 80/4.5 microg qd maintenance plus additional inhalations for symptom relief), budesonide/formoterol 80/4.5 microg qd for maintenance (fixed combination), or higher-dose budesonide 320 microg qd (fixed-dose budesonide). Blinded as-needed medication (terbutaline 0.4 microg) was provided in both fixed-dose groups. RESULTS: SMART prolonged the time to first exacerbation vs fixed-dose budesonide (p = 0.02) and fixed-dose combination (p < 0.001). Rates of exacerbation requiring medical intervention were reduced by 70 to 79% with SMART vs fixed-dose budesonide and fixed-dose combination (0.08/patient vs 0.28/patient and 0.40/patient, respectively; both p < 0.001). Mild exacerbation days and awakenings were significantly lower with SMART; yearly growth improved by 1.0 cm vs fixed-dose budesonide (p < 0.01). CONCLUSION: The SMART regimen using budesonide/formoterol for both maintenance and as-needed symptom relief reduces the exacerbation rate compared with both fixed-dose combination and higher fixed-dose ICS alone in children with asthma.

BACKGROUND: Few large-scale studies have examined inhaled corticosteroid treatment in preschool children with recurrent wheeze. We assessed the effects of ciclesonide in preschool children with recurrent wheeze. METHODS: We included children 2-6 yrs with recurrent wheeze and a positive asthma predictive index or aeroallergen sensitization to, excluding patients with episodic viral wheezing. After a 2-4-week baseline period, patients with ongoing symptoms or rescue medication use were randomised to once-daily ciclesonide 40, 80, 160 µg or placebo for 24 weeks. RESULTS: The number of wheeze exacerbations requiring systemic corticosteroids was unexpectedly low in all groups: 25 (10.2%) in placebo group, as compared to 11 (4.4%), 18 (7.3%), and 17 (6.7%) in ciclesonide 40, 80, and 160 µg, respectively. The difference in time to first exacerbation was not significantly different between groups (p = 0.786), but the difference in exacerbation rates between placebo and the pooled ciclesonide groups was (p = 0.03). Large and significant (p < 0.0001) improvements in symptom scores and rescue medication use occurred in all groups, including placebo. Improvements in FEV(1) and FEF(25-75) (measured in 284 4-6 yr olds) were larger in the ciclesonide than in the placebo group. No differences in safety parameters (adverse events, height growth, serum and urinary cortisol levels) between ciclesonide and placebo were observed. CONCLUSIONS: In preschool children with recurrent wheeze and a positive asthma predictive index, ciclesonide modestly reduces wheeze exacerbation rates and improves lung function. A large placebo response and unexpected selection of patients with mild disease may have affected outcomes, highlighting the heterogeneity of preschool wheezing disorders.

Ciclesonide is an onsite-activated inhaled corticosteroid (ICS) for the treatment of asthma. This study compared the efficacy, safety and effect on quality of life (QOL) of ciclesonide 160 microg (ex-actuator; nominal dose 200 microg) vs. budesonide 400 microg (nominal dose) in children with asthma. Six hundred and twenty-one children (aged 6-11 yr) with asthma were randomized to receive ciclesonide 160 microg (ex-actuator) once daily (via hydrofluoroalkane metered-dose inhaler and AeroChamber Plus spacer) or budesonide 400 microg once daily (via Turbohaler) both given in the evening for 12 wk. The primary efficacy end-point was change in forced expiratory volume in 1 s (FEV1). Additional measurements included change in daily peak expiratory flow (PEF), change in asthma symptom score sum, change in use of rescue medication, paediatric and caregiver asthma QOL questionnaire [PAQLQ(S) and PACQLQ, respectively] scores, change in body height assessed by stadiometry, change in 24-h urinary cortisol adjusted for creatinine and adverse events. Both ciclesonide and budesonide increased FEV1, morning PEF and PAQLQ(S) and PACQLQ scores, and improved asthma symptom score sums and the need for rescue medication after 12 wk vs. baseline. The non-inferiority of ciclesonide vs. budesonide was demonstrated for the change in FEV1 (95% confidence interval: -75, 10 ml, p = 0.0009, one-sided non-inferiority, per-protocol). In addition, ciclesonide and budesonide showed similar efficacy in improving asthma symptoms, morning PEF, use of rescue medication and QOL. Ciclesonide was superior to budesonide with regard to increases in body height (p = 0.003, two-sided). The effect on the hypothalamic-pituitary-adrenal axis was significantly different in favor of ciclesonide treatment (p < 0.001, one-sided). Both ciclesonide and budesonide were well tolerated. Ciclesonide 160 microg once daily and budesonide 400 microg once daily were effective in children with asthma. In addition, in children treated with ciclesonide there was significantly less reduction in body height and suppression of 24-h urinary cortisol excretion compared with children treated with budesonide after 12 wk.
