BACKGROUND: A hypotonic aqueous nasal spray of ciclesonide is indicated for the treatment of allergic rhinitis (AR). A new nasal aerosol formulation of ciclesonide containing a hydrofluoroalkane propellant delivered via a metered-dose inhaler (CIC-HFA) is currently in clinical development as a potential treatment for AR. OBJECTIVES: To study the efficacy and safety of once-daily administration of CIC-HFA 80 or 160 μg compared with placebo in subjects 12 years and older with seasonal AR (SAR). METHODS:Subjects 12 years and older with a ≥ 2-year history of SAR were randomized in a placebo-controlled, double-blind, parallel-group, multicenter study to receive CIC-HFA 80 or 160 μg or placebo once daily in the morning for 2 weeks. Changes from baseline in reflective total nasal symptom scores (rTNSSs), instantaneous TNSSs (iTNSSs), and reflective total ocular symptom scores (rTOSSs) in subjects with a baseline rTOSS of ≥ 5.00 were evaluated. Treatment-emergent adverse events were monitored throughout the study. RESULTS:Seven hundred seven subjects were randomized. From baseline, CIC-HFA 80 or 160 μg demonstrated 15.1% and 16.0% reductions in rTNSSs (P < .0001, 3.7% for placebo), 14.3% and 15.4% reductions in iTNSSs (P < .0001, 3.9% for placebo), and 15.7% and 15.0% reductions in rTOSSs (P < .001, 6.8% for placebo). The overall incidence of treatment-emergent adverse events was low and comparable between the CIC-HFA and placebo groups. CONCLUSIONS: In this study, once-daily treatment with CIC-HFA 80 or 160 μg demonstrated statistically significant improvements in nasal and ocular symptoms of SAR. Both doses of active treatment were well tolerated.
