24-h Nitrogen dioxide concentration is associated with cooking behaviors and an increase in rescue medication use in children with asthma

Background: Ciclesonide (CIC) is an inhaled corticosteroid (ICS) approved for the maintenance treatment of asthma in patients ages ≥ 12 years. The prodrug aspect of CIC is associated with a safety profile that may make it ideal for children. Objective: The objective was to summarize efficacy results from the eight phase III, randomized, double-blind, controlled trials in children with asthma conducted during CIC clinical development. Methods: Four trials compared CIC 40, 80, or 160 µg/day with placebo. Two trials compared CIC 160 µg/day with fluticasone propionate 200 µg/day, one trial compared CIC 80 or 160 µg/day with fluticasone 200 µg/day, and one trial compared CIC 160 µg/day with budesonide 400 µg/day. Results: The primary end point was met by at least two CIC doses versus placebo in the trials in which the primary end point was the change from baseline in lung function outcome (forced expiratory volume in 1 second [FEV1] % predicted or morning peak expiratory flow [PEF]). A trial that compared CIC with placebo did not meet the primary end point of superiority in time-to-first severe wheeze exacerbation or lack of improvement. The primary end point of noninferiority to the active control (fluticasone or budesonide) in the change from baseline in a lung function outcome (FEV1, morning PEF, evening PEF) was met with the CIC 160-µg dose in all active control trials. CIC generally demonstrated statistically significant improvements in forced expiratory flow at 25%‐75% of forced vital capacity, asthma symptoms, rescue medication use, and asthma control when compared with placebo and noninferiority for these outcomes compared with fluticasone or budesonide. Conclusion: In children with asthma, once-daily CIC significantly improved large and small airway function, asthma symptoms, and asthma control, and reduced rescue medication use compared with placebo. CIC was comparable with other ICS used to treat asthma in children, which demonstrated its worth for the pediatric population.

Background: In chronic obstructive pulmonary disease (COPD), both the time needed for patients to gain symptom improvement with long-acting bronchodilator therapy and whether an early response is predictive of a sustained response is unknown. This study aimed to investigate how quickly meaningful symptom responses are seen in patients with COPD with bronchodilator therapy and whether these responses are sustained. Methods: Early MAXimisation of bronchodilation for improving COPD stability (EMAX) was a 24-week, double-blind, double-dummy, parallel-group trial that randomised patients to umeclidinium/vilanterol (UMEC/VI), umeclidinium or salmeterol. Daily Evaluating Respiratory Symptoms in COPD (E-RS:COPD) score and rescue salbutamol use were captured via an electronic diary and analysed initially in 4-weekly periods. Post hoc analyses assessed change from baseline in daily E-RS:COPD score and rescue medication use weekly (Weeks 1–8), and association between E-RS:COPD responder status at Weeks 1–4 and later time points. Results: In the intent-to-treat population ( n = 2425), reductions from baseline in E-RS:COPD scores and rescue medication use were apparent from Day 2 with all treatments. Treatment differences for UMEC/VI versus either monotherapy plateaued by Week 4–8 and were sustained at Weeks 21–24; improvements were consistently greater with UMEC/VI. For all treatments, most patients (60–85%) retained their Weeks 1–4 E-RS:COPD responder/non-responder status at Weeks 21−24. Among patients receiving UMEC/VI who were E-RS:COPD responders at Weeks 1–4, 70% were responders at Weeks 21–24. Conclusion: Patients with symptomatic COPD had greater potential for early symptom improvements with UMEC/VI versus either monotherapy. This benefit was generally maintained for 24 weeks. Early monitoring of treatment response can provide clinicians with an early indication of a patient’s likely longer-term response to prescribed bronchodilator treatment and will facilitate appropriate early adjustments in care.
