BACKGROUND To our knowledge, there are no published studies that evaluated the efficacy of azelastine hydrochloride nasal spray in combination with an intranasal corticosteroid, although anecdotal reports of the use of these agents in combination are common. OBJECTIVE To determine if greater efficacy could be achieved with the intranasal antihistamine azelastine and the intranasal corticosteroid fluticasone propionate used concurrently compared with the efficacy of each agent alone. METHODS This randomized, 2-week, multicenter, double-blind trial was conducted during the Texas mountain cedar season. After a 5-day placebo lead-in period, 151 patients with moderate to severe nasal symptoms were randomized to treatment with the following: (1) azelastine nasal spray, 2 sprays per nostril twice daily; (2) fluticasone nasal spray, 2 sprays per nostril once daily; or (3) azelastine nasal spray, 2 sprays per nostril twice daily, plus fluticasone nasal spray, 2 sprays per nostril once daily. The primary efficacy variable was the change from baseline in the total nasal symptom score (TNSS), consisting of sneezing, itchy nose, runny nose, and nasal congestion. RESULTS All 3 groups had statistically significant (P < .001) improvements from their baseline TNSS after 2 weeks of treatment. The TNSS improved 27.1% with fluticasone nasal spray, 24.8% with azelastine nasal spray, and 37.9% with the 2 agents in combination (P < .05 vs either agent alone). All 3 treatments were well tolerated. CONCLUSIONS The significant improvement in the TNSS with combination therapy relative to the individual agents alone is in contrast to previously published studies that found no advantage with an oral antihistamine and an intranasal corticosteroid in combination. Azelastine nasal spray and fluticasone nasal spray in combination may provide a substantial therapeutic benefit for patients with seasonal allergic rhinitis compared with therapy with either agent alone.

BACKGROUND A proof-of-concept study suggested that combination therapy with commercial azelastine hydrochloride nasal spray and fluticasone propionate nasal spray significantly improved nasal symptoms of seasonal allergic rhinitis compared with either agent alone. OBJECTIVE To compare an azelastine-fluticasone combination nasal spray administered in a single-delivery device with a commercially available azelastine nasal spray and fluticasone nasal spray. METHODS This 14-day, multicenter, randomized, double-blind study was conducted during the Texas mountain cedar season. After a 5-day placebo lead-in, 610 patients with moderate-to-severe nasal symptoms were randomized to treatment with (1) azelastine nasal spray, (2) fluticasone nasal spray, (3) combination azelastine and fluticasone nasal spray, or (4) placebo nasal spray. All treatments were given as 1 spray per nostril twice daily. The primary efficacy variable was the change from baseline in the total nasal symptom score (TNSS), consisting of nasal congestion, runny nose, itchy nose, and sneezing. RESULTS All 3 active groups were statistically superior (P <or= .02) to placebo, and the combination was statistically superior (P <or= .003) to either agent alone. The TNSS improved by 28.4% with combination azelastine-fluticasone, 20.4% with fluticasone, 16.4% with azelastine, and 11.2% with placebo. All 3 treatments were well tolerated. CONCLUSIONS The combination azelastine-fluticasone nasal spray provided statistically significant improvement in the TNSS and additive clinical benefit compared with either agent alone in patients with moderate-to-severe seasonal allergic rhinitis.

BACKGROUND The efficacy and safety of mometasone furoate aqueous nasal spray (MFNS; Nasonex) 200 microg once daily for the treatment and prophylaxis of seasonal allergic rhinitis (SAR) and treatment of perennial rhinitis have been demonstrated in adults. However, the dose response of MFNS in pediatric patients has not yet been characterized. OBJECTIVE This study was conducted to determine the dose-response relationship of 3 different doses of MFNS in a pediatric population. METHODS This was a multicenter, double-blind, active- and placebo-controlled study of 679 children 6 to 11 years of age with histories of SAR and documented positive skin test responses. Patients were randomized to one of the following treatment groups for 4 weeks: MFNS 25 microgram once daily, MFNS 100 microgram once daily, MFNS 200 microgram once daily, beclomethasone dipropionate 84 microgram twice daily (168 microgram/day), or placebo. Physician evaluations were performed at days 4, 8, 15, and 29, and patient evaluations were analyzed for days 1 to 15 and 16 to 29. RESULTS The mean reduction from baseline in physician-evaluated total nasal symptom scores at day 8 (the primary efficacy variable) was significantly greater in the MFNS and beclomethasone dipropionate groups than in the placebo group (P </=.02). No significant differences were observed among the 3 MFNS groups. However, as treatment continued, symptoms in patients treated with MFNS 100 or 200 microgram once daily continued to improve, whereas those treated with MFNS 25 microgram once daily demonstrated little further improvement. By day 29, MFNS 100 and 200 microgram once daily both were significantly more effective than MFNS 25 microgram once daily in relieving symptoms of SAR, but MFNS 200 microgram provided no additional benefit over MFNS 100 microgram. All doses of MFNS were well tolerated, and cosyntropin stimulation tests performed before and after treatment found no evidence of hypothalamic-pituitary-adrenal axis suppression. CONCLUSION These results indicate that the most appropriate therapeutic dosage of MFNS in the treatment of SAR in children 6 to 11 years of age is 100 microgram once daily. In addition, MFNS at doses up to 200 microgram once daily for 4 weeks was well tolerated and had no detectable effects on hypothalamic-pituitary-adrenal axis function.

BACKGROUND Topical nasal corticosteroids are rapidly gaining acceptance as first-line therapy for seasonal allergic rhinitis, but there is a desire for effective corticosteroids with an improved safety profile over existing products. OBJECTIVE A multicenter, double-blind dose ranging study was conducted to compare the activity and tolerance of four doses of mometasone furoate nasal spray (tradename Nasonex) and placebo in adult patients with seasonal allergic rhinitis. METHODS Four hundred eighty patients with seasonal allergic rhinitis were enrolled and randomized to receive mometasone furoate nasal spray 50 micrograms (n = 96), 100 micrograms (n = 95), 200 micrograms (n = 98) or 800 micrograms (n = 95), or placebo vehicle (n = 95) once daily for 28 days. RESULTS All of the doses of mometasone furoate nasal spray showed activity in reducing the severity of rhinitis. The 200-microgram dose reduced total nasal symptom scores and total symptom scores throughout the study (P < .05 versus placebo vehicle). The 50-microgram dose and the 100-microgram dose showed less consistent activity at early timepoints (days 3 and 7), while the 800 microgram dose did not provide significant additional benefits over the 200-microgram dose. All dose levels were well tolerated CONCLUSION The results of this trial indicate that 200 micrograms once daily is the optimum dose of mometasone furoate nasal spray for the treatment of seasonal allergic rhinitis.

BACKGROUND Few studies have directly compared the efficacy of intranasal corticosteroids with that of leukotriene receptor antagonists for the treatment of daytime and nighttime symptoms of seasonal allergic rhinitis (SAR). OBJECTIVE To compare fluticasone propionate aqueous nasal spray, 200 microg daily, with oral montelukast, 10 mg daily, for the relief of SAR symptoms. METHODS Patients with SAR 15 years or older were randomized to receive either fluticasone propionate (n = 367) or montelukast (n = 369) in this double-blind, double-dummy, parallel-group study. The primary efficacy measure was the mean change from baseline in daytime total nasal symptom scores (TNSSs) (the sum of 4 daytime individual nasal symptom scores [INSSs] assessing nasal congestion, itching, rhinorrhea, and sneezing), averaged across weeks 1 and 2. Secondary efficacy measures included the 4 daytime INSSs, nighttime TNSSs (the sum of 3 nighttime INSSs assessing congestion on awakening, difficulty going to sleep, and nighttime awakenings), and the 3 nighttime INSSs averaged across weeks 1 and 2. RESULTS Mean changes from baseline in daytime TNSSs (P < .001), all daytime INSSs (P < .001), nighttime TNSSs (P < .001), and all nighttime INSSs (P < or = .02) showed significant differences favoring fluticasone propionate over montelukast across 2 weeks of treatment. CONCLUSION Compared with montelukast, fluticasone propionate provided significantly greater improvement in daytime and nighttime SAR symptoms.

BACKGROUND A nasal spray containing the antiallergy agent olopatadine hydrochloride is being developed for the treatment of seasonal allergic rhinitis (SAR) to mountain cedar. OBJECTIVE To evaluate the safety and efficacy of 2 concentrations of olopatadine nasal spray vs placebo nasal spray in patients with SAR to mountain cedar. METHODS This was a multicenter, randomized, double-blind, placebo-controlled study. After a 3- to 21-day placebo run-in, 677 patients aged 12 to 81 years were randomized to receive 0.4% or 0.6% olopatadine or placebo, 2 sprays per nostril twice daily for 2 weeks. Patients evaluated morning and evening reflective and instantaneous nasal symptoms (sneezing, stuffy nose, runny nose, and itchy nose, which compose the total nasal symptom score [TNSS]) and ocular symptoms. RESULTS Olopatadine spray (0.4% and 0.6%) was statistically significantly superior to placebo for percentage change from baseline in overall reflective and instantaneous TNSSs. Also, 0.6% olopatadine was statistically significantly superior to placebo for reducing the reflective and instantaneous assessments of sneezing, runny nose, itchy nose, stuffy nose, itchy eyes, and watery eyes. Olopatadine spray exhibited a safety profile comparable with that of placebo. CONCLUSIONS Olopatadine nasal spray (0.4% and 0.6%) provided statistically significant improvements in allergic rhinitis symptoms compared with placebo regarding TNSSs and individual symptoms, including congestion, itchy and runny nose, sneezing, and itchy and watery eyes, in patients with SAR to mountain cedar. Olopatadine nasal spray administered twice daily was safe and well tolerated in adolescents and adults.

BACKGROUND Ciclesonide is an investigational corticosteroid under development for treatment of allergic rhinitis. Ciclesonide is converted to active metabolite, desisobutyryl-ciclesonide (des-CIC), by upper and lower airway esterases. In vitro studies in human nasal epithelial cells and bronchial epithelial cells have demonstrated a long duration of anti-inflammatory activity of des-CIC. OBJECTIVE To evaluate the dose-dependent efficacy and safety of a hypotonic intranasal formulation of ciclesonide in patients with seasonal allergic rhinitis (SAR). METHODS This was a phase 2, randomized, parallel-group, double-blind, placebo-controlled study. Adults (n = approximately 145 per treatment group) with a minimum 2-year history of SAR received placebo or ciclesonide (25, 50, 100, or 200 microg/d) for 14 days. The primary end point was change in the sum of morning and evening reflective total nasal symptom scores (TNSSs) over 2 weeks. Safety was monitored throughout the study. RESULTS Ciclesonide, 100 microg/d (P = .04) and 200 microg/d (P = .003), significantly improved the sum of morning and evening reflective TNSS vs placebo at more than 2 weeks of treatment. Baseline values for morning and evening reflective TNSS ranged from 17.80 to 18.82 across treatment groups. The average change from baseline in reflective TNSS was -4.2 for placebo and -4.8, -4.8, -5.3, and -5.8 for ciclesonide, 25, 50, 100, and 200 microg/d, respectively. There were no dose-related differences in the incidence of adverse events among treatment groups. CONCLUSIONS Results from this study indicate that 100-microg and 200-microg daily doses of ciclesonide are effective in the treatment of SAR. Ciclesonide, 200 microg/d, appears to be the optimal dose studied for reducing the symptoms of SAR while maintaining an acceptable safety profile.

BACKGROUND Fluticasone propionate is a topically active glucocorticoid with potent antiinflammatory activity in the treatment of asthma. OBJECTIVE This study evaluated the safety and efficacy of fluticasone propionate administered via the Diskus and Diskhaler powder delivery devices in subjects with mild-to-moderate asthma. METHODS Fluticasone propionate (500 microg twice daily) or placebo was administered via the Diskus and Diskhaler to 213 adolescent and adult asthma subjects in a randomized, double-blind, double-dummy, parallel-group study for 12 weeks. Subjects were stratified according to baseline therapy of inhaled corticosteroids or beta2-agonists alone. Subjects were dropped from the study if they met predefined criteria for lack of efficacy. RESULTS Fluticasone propionate improved pulmonary function both in subjects previously treated with inhaled corticosteroids or beta2-agonists alone. At endpoint, fluticasone propionate significantly improved forced expiratory volume in 1 second (P < .001), morning and evening peak expiratory flow (P < .001), and asthma symptom scores (P < or = .016), and significantly reduced nighttime awakenings (P = .016; Diskhaler group only) and rescue albuterol use (P < .001). Overall, efficacy measurements for the Diskus and Diskhaler were similar. More placebo-treated subjects (34%) withdrew from the study due to lack of efficacy than subjects in the Diskus (5%) or Diskhaler (5%) groups. The incidence and severity of adverse events were similar across groups. Measurement of plasma fluticasone propionate and cortisol concentrations showed no apparent influence of device on systemic exposure. CONCLUSION Fluticasone propionate powder, administered via the Diskus or Diskhaler inhalation devices, was well tolerated and effective in the treatment of mild-to-moderate persistent asthma.

Azelastine nasal spray is commercially available as a 0.1% w/v solution and is recommended for twice-daily dosing. Increasing the azelastine concentration to 0.15% may be effective with once-daily dosing without increasing the incidence of adverse events. This study evaluated the efficacy and safety of azelastine 0.15% nasal spray at a dosage of 2 sprays/nostril once daily. This randomized, double-blind, placebo-controlled study was conducted in subjects with moderate-to-severe seasonal allergic rhinitis (SAR) during the 2007/2008 Texas Mountain Cedar season. In total, 536 subjects were randomized to 2 sprays/nostril once daily (A.M.) of azelastine 0.15% or placebo. The primary efficacy variable was change from baseline in a 12-hour reflective Total Nasal Symptom Score (TNSS), consisting of nasal congestion, runny nose, itchy nose, and sneezing. The key secondary variable was change from baseline in 24-hour instantaneous TNSS, which determines the duration of action and effective dosing interval. After 2 weeks, the mean improvement in 12-hour reflective TNSS and percentage improvement in 12-hour reflective TNSS were significant (p < 0.001) with azelastine 0.15% (19%) compared with placebo (10%). The improvement in 24-hour instantaneous TNSS also was significant (p < 0.001) for azelastine 0.15% compared with placebo, supporting efficacy with once-daily dosing. All individual TNSS symptoms were significantly (p < 0.01) improved with azelastine 0.15% compared with placebo. With the exception of bitter taste (4.5%) and nasal discomfort (4.5%), adverse events with azelastine 0.15% were reported with an incidence similar to placebo. Azelastine 0.15% nasal spray was effective and well tolerated in subjects with SAR with once-daily dosing.

Safety and tolerability of fexofenadine hydrochloride, 15 and 30 mg, twice daily in children aged 6 months to 2 years with allergic rhinitis

Frank C. Hampel; Barbara Kittner; Julius van Bavel

BACKGROUND Antihistamines are an established first-line treatment for allergic rhinitis and are widely prescribed in infants for allergic symptoms. OBJECTIVE To establish the safety and tolerability of fexofenadine hydrochloride in children aged 6 months to 2 years in 2 studies (T/3001 and T/3002). METHODS Both studies had a multicenter, randomized, placebo-controlled design. Mean treatment duration was 8 days. Subjects were randomized (T/3001, n = 174; and T/3002, n = 219) to twice-daily fexofenadine hydrochloride, 15 or 30 mg, or placebo mixed with a standard vehicle. RESULTS In the combined population, the incidence of treatment-emergent adverse events (TEAEs) was comparable between groups (placebo, 48.2% [96/199]; fexofenadine hydrochloride, 15 mg, 40.0% [34/85]; and fexofenadine hydrochloride, 30 mg, 35.2% [38/108]). Vomiting was the most common TEAE (placebo, 13.6%; fexofenadine hydrochloride, 15 mg, 14.1%; and fexofenadine hydrochloride, 30 mg, 5.6%). Most TEAEs were unrelated to study medication, as evaluated by investigators; those possibly related to study medication were mild or moderate in intensity. No clinical differences were seen between fexofenadine and placebo for vital signs, electrocardiographic results, or physical examination results. CONCLUSION Fexofenadine hydrochloride, 15 or 30 mg, given for a mean duration of 8 days is well tolerated, with a good safety profile, in children aged 6 months to 2 years.
