Background Ciclesonide hydrofluoroalkane nasal aerosol (CIC-HFA) is currently in development as a potential treatment for allergic rhinitis. The objective of this study was to determine the efficacy and safety of CIC-HFA compared to placebo in subjects with perennial allergic rhinitis (PAR). Methods Subjects ≥12 years of age with a ≥2 year history of PAR were randomized in a placebo-controlled, double-blind, parallel group, multicenter study to CIC-HFA 74 μg (N = 298), CIC-HFA 148 μg (N = 505), or placebo (N = 307) QD AM for 26 weeks. Subject-reported change from baseline in the average of AM and PM reflective total nasal symptom score (rTNSS) and instantaneous total nasal symptom score (iTNSS) averaged over the first 6 weeks of treatment period were key endpoints and were calculated as a sum of the 4 individual nasal symptoms of congestion, runny nose, sneezing, and nasal itching each on a scale of 0 (no signs/symptoms evident) to 3 (severe symptoms). Change from baseline in the individual reflective and instantaneous nasal symptom scores over the first 6 weeks of treatment period were also evaluated. Treatment-emergent adverse events (TEAEs) were assessed throughout the study. Results CIC-HFA 74 μg and CIC-HFA 148 μg doses demonstrated a statistically significant improvement in rTNSS (LS mean change 0.70 & 0.54 respectively, P ≤ 0.001 for both), iTNSS (LS mean change 0.58 & 0.42 respectively, P ≤ 0.05 for both) and improvements in individual reflective and instantaneous nasal symptoms (P ≤ 0.05 for all, unadjusted for multiplicity) at 6 weeks from baseline. The overall incidence of TEAEs was low and comparable between the CIC treatment groups and placebo. The most frequently reported TEAEs (≥2% of subjects in any treatment group) were nausea, headache, sinus headache, cough, upper respiratory tract infection, instillation site discomfort, nasal discomfort, nasopharyngitis, sinusitis, oropharyngeal pain, and epistaxis. Conclusions In this study, once-daily treatment with CIC-HFA 74μg or CIC-HFA 148μg demonstrated statistically significant improvements in the nasal symptoms of PAR. Both active treatments were well tolerated.
