Efficacy and safety of beclomethasone dipropionate nasal aerosol in pediatric patients with seasonal allergic rhinitis.

BACKGROUND: Aerosolized intranasal corticosteroid formulations are desirable for many patients with allergic rhinitis (AR), especially children, who wish to avoid the "wet feeling" and "drip down the throat" associated with aqueous formulations. Beclomethasone dipropionate (BDP) hydrofluoroalkane nasal aerosol has been shown to be safe and effective in adolescents and adults with AR. OBJECTIVE: To evaluate the efficacy and safety of BDP nasal aerosol in pediatric patients with moderate to severe seasonal AR. METHODS: In this double-blinded, placebo-controlled study, children (6-11 years of age) with seasonal AR were randomized to once-daily treatment with BDP nasal aerosol 80 µg (n = 239) or 160 µg (n = 242) or placebo (n = 234). The primary end point was change from baseline in average morning and evening reflective total nasal symptom score over the 2-week treatment period. RESULTS: Treatment with BDP nasal aerosol showed significantly greater improvements in average morning and evening reflective total nasal symptom score vs placebo (80 µg, -0.71; 160 µg, -0.76; P < .001 for the 2 comparisons). Similarly, significantly greater improvements in average morning and evening instantaneous total nasal symptom score were seen with BDP nasal aerosol vs placebo (80 µg, -0.63; 160 µg, -0.73; P < .001 for the 2 comparisons). The incidence of adverse events from BDP nasal aerosol was comparable to that from placebo. CONCLUSION: BDP nasal aerosol (80 or 160 µg/d) provided significant and clinically meaningful nasal symptom relief and an established overall safety profile similar to that of placebo, suggesting that it is an effective and well-tolerated treatment option for pediatric patients with moderate to severe seasonal AR.

Patient satisfaction with beclomethasone dipropionate nasal aerosol device with integrated dose counter during daily use.

Some patients with allergic rhinitis (AR) may prefer a "dry" intranasal corticosteroid aerosol to avoid certain sensory perceptions such as the "wet feeling in the nose" and the "dripping down the throat" associated with aqueous nasal sprays. A nonaqueous hydrofluoroalkane-propelled beclomethasone dipropionate (BDP) nasal aerosol with an established efficacy and safety profile was approved to treat the nasal symptoms associated with AR in adult and adolescent patients. This study was designed to evaluate ease of use and patient satisfaction with the BDP nasal aerosol device in patients with perennial AR (PAR). In this phase 3, randomized, double-blind, parallel-group, placebo-controlled study, eligible patients (≥12 years of age) with PAR were randomly assigned to receive BDP nasal aerosol at 320 micrograms/day or placebo for 6 weeks. At the end of the treatment period, patients assessed device ease of use and satisfaction with the device using a questionnaire with a 5-point representative scale (not at all, not very, neither nor, somewhat, very [certain/easy/satisfactory]). Nearly all patients (89.7%) reported that the BDP nasal aerosol device with integrated dose counter was "very easy" or "somewhat easy" to use. The majority of patients (87.5%) also indicated that it was "very easy" or "somewhat easy" to tell when the device was empty, compared with only 42.3% who were "very certain" or "somewhat certain" of being able to tell when previously used aqueous nasal spray devices were empty. Overall, patient satisfaction with the BDP nasal aerosol device was high: 65.7% responded that they were "very satisfied" or "somewhat satisfied" and only 3.6% were "not satisfied at all" or "not very satisfied." These results indicate that the majority of patients considered the BDP nasal aerosol device easy to use and reported a high degree of satisfaction with the device compared with other nasal sprays they had used in the past.

Beclomethasone dipropionate nasal aerosol with an integrated dose counter: functionality and performance.

Consistent medication delivery is critical for disease control including symptom management of allergic rhinitis (AR). Available aqueous intranasal corticosteroid devices lack an accurate dose (actuation) counter, which may lead patients to prematurely discard a unit or use a unit beyond its labeled number of actuations, therefore impacting patient adherence. Beclomethasone dipropionate (BDP) nasal aerosol, a nonaqueous hydrofluoroalkane formulation in a device with a novel integrated dose counter and an established efficacy/safety profile, was approved to treat AR-associated nasal symptoms in adolescent and adult patients. This study was designed to evaluate performance of the BDP nasal aerosol device with an integrated dose counter in perennial AR (PAR) patients. In a 6-week, double-blind, placebo-controlled study in PAR patients (≥12 years), patients were randomized to receive once-daily BDP nasal aerosol at 320 micrograms or placebo. In addition to assessing the primary efficacy end point, patients evaluated the performance of the device and reliability, accuracy, and functionality of the dose counter. Concordance between daily patient-reported actuations and dose counter readings was assessed by classifying discrepancies into four categories: "fire not count," "count not fire," "count unknown fire," and "count up unknown fire." Analysis was performed for the total device completer population (n = 374), which included all randomized patients completing ≥80% of actuations during the last 4 weeks of treatment. Low discrepancy rates were shown for all discrepancy categories. Of 41,891 patient-reported actuations, only 159 discrepancies (diary versus counter) were noted, resulting in an overall discrepancy rate of 0.38 per 100 actuations. The medically important discrepancy rate of "fire not count" was low (0.09 per 100 actuations). Overall, 79.1% of patients reported zero discrepancies, 9.4% reported one discrepancy, and 6.4% reported two discrepancies. These results showed the functionality and reliability of the BDP nasal aerosol device with an integrated dose counter in a clinical setting. (ClinicalTrials.gov identifier: NCT01134705.).

Efficacy, safety, and optimal dose selection of beclomethasone dipropionate nasal aerosol for seasonal allergic rhinitis in adolescents and adults.

OBJECTIVE: Some patients with allergic rhinitis (AR) may prefer nonaqueous intranasal corticosteroid aerosols because of unwanted attributes of aqueous formulations. The mandatory removal of chlorofluorocarbon-propelled nonaqueous aerosols from the market limited available treatment options. To fulfill this unmet need, a nonaqueous, hydrofluoroalkane-propelled beclomethasone dipropionate (BDP) nasal aerosol was developed and approved for treatment of AR nasal symptoms. As part of the development program, this dose-ranging study evaluated three doses of BDP nasal aerosol to determine the optimally safe and effective dose for adolescent and adult patients (≥12 years old) with seasonal AR (SAR). METHODS: After a 7 to 21 day placebo run-in period, eligible patients with SAR were randomly assigned to once-daily BDP nasal aerosol 80 µg, 160 µg, 320 µg, or placebo. The primary endpoint was the change from baseline in average a.m. and p.m. patient-reported reflective total nasal symptom scores (rTNSS) over 2 weeks. Safety and tolerability were also assessed. A potential study limitation could be lack of objective assessment of AR symptoms. RESULTS: Significant improvements were seen in average a.m. and p.m. rTNSS (least squares [LS] mean treatment difference, -0.63; 95% CI: -1.13, -0.13; p = 0.013) as well as in average a.m. and p.m. instantaneous TNSS (iTNSS; LS mean treatment difference, -0.60; 95% CI: -1.09, -0.11; p = 0.016) with BDP nasal aerosol 320 µg/day compared with placebo. Although there were numerical improvements from baseline in patient-reported rTNSS and iTNSS with BDP nasal aerosol 80 µg and 160 µg, these doses did not achieve statistical significance compared with placebo. BDP nonaqueous nasal aerosol was well tolerated at all doses tested, with a safety profile comparable to that of placebo. CONCLUSIONS: These data indicate that 320 µg/day of BDP nasal aerosol is the optimally safe and effective dose for the treatment of SAR in adolescent and adult patients.
