Background: Ciclesonide is an intranasal corticosteroid approved for the treatment of allergic rhinitis (AR).
Objective: To evaluate the efficacy, safety, and quality-of-life benefits of intranasal ciclesonide, 200 microg once daily, for the treatment of perennial AR (PAR).
Methods: In this multicenter, randomized, double-blind, placebo-controlled study, adults and adolescents with at least a 2-year history of PAR received intranasal ciclesonide, 200 microg, or placebo once daily for 6 weeks. Patient-evaluated total nasal symptom scores (TNSSs), physician-assessed overall nasal signs and symptoms severity scores, and Rhinoconjunctivitis Quality of Life Questionnaire scores were evaluated.
Results: Patient baseline characteristics were similar in the ciclesonide (n = 238) and placebo (n = 233) groups and were consistent with moderate PAR severity. Ciclesonide therapy significantly reduced average morning and evening reflective TNSSs compared with placebo (P < .001) and significantly reduced average morning and evening instantaneous TNSSs (P = .001) over 6 weeks of treatment. At the end point, a greater decrease from baseline was observed in physician-assessed overall nasal signs and symptoms severity for the ciclesonide group compared with the placebo group (P = .051). An appreciable improvement in combined Rhinoconjunctivitis Quality of Life Questionnaire scores at the end point was also observed in the ciclesonide group (P = .01 vs placebo). The frequency of adverse events was similar between treatment groups.
Conclusions: In this study, intranasal ciclesonide treatment was associated with significant reductions in nasal symptoms and appreciable improvements in health-related quality of life in adult and adolescent patients with PAR. Ciclesonide was well tolerated, with a safety profile comparable with that of placebo.
