ciclesonide and Rhinitis--Allergic--Seasonal

During the last few years, fixed combinations of intranasal antihistamines and corticosteroids have been introduced for treatment of allergic rhinitis. The aim of this systematic review was to assess recent patents and clinical evidence for fixed combinations of intranasal antihistamines and intranasal corticosteroids in allergic rhinitis. Data base searches revealed that intranasal combinations of the antihistamine azelastine with the corticosteroids mometasone furoate, ciclesonide and fluticasone propionate, respectively, have been patented. Four randomized, double-blinded, parallel-group, placebo-controlled, multicenter trials sponsored by the manufacturer evaluated the fixed combination of intranasal azelastine 125 µg and fluticasone propionate 50 µg administered as one dose per nostril b.i.d. in patients with moderate-to-severe symptomatic allergic rhinitis ≥ 12 years of age. Three of the studies were published as a meta-analysis which found the fixed combination of azelastine and fluticasone propionate statistically significantly more efficacious in reducing baseline total nasal symptom score by 5.7 as compared to azelastine (4.4; P < 0.001), fluticasone propionate (5.1; P < 0.001) and placebo (3.0; P < 0.001). The findings were supported by secondary assessments of scores of specific nasal and ocular symptoms. Pharmacokinetic studies have revealed no drug-drug interactions but a discrete increase in bioavailability of fluticasone propionate which was considered clinically unimportant. Further efficacy and quality-of-life studies of combination products of nasal antihistamines and corticosteroids are needed, especially, in primary care settings and in children before fixed combination treatment can be considered first line therapy in allergic rhinitis. Fixed combination treatment of azelastine and fluticasone propionate may offer additional benefit to selected populations of adolescents and adults with moderate-to-severe symptoms.

Allergic rhinitis is considered one of the most common afflictions of humans, affecting up to 30% of the world's population, and is increasing in incidence. Primary symptoms, comorbid conditions and complications of this disorder exact a significant toll, resulting in an enormous physical, social and economic impact on society. Single-season allergic rhinitis accounts for approximately 20% of cases of allergic rhinitis with another 40% having mixed seasonal-perennial presentations. Management of this disorder encompasses several treatment options, with intranasal corticosteroids recommended as first-line treatment in moderate-to-severe seasonal allergic rhinitis in current practice parameters. Ciclesonide is the most recently approved product in this category for the management of seasonal allergic rhinitis and is the subject of this article.

Ciclesonide nasal spray delivers the corticosteroid ciclesonide as a hypotonic spray via a metered-dose manual pump. Systemic exposure to ciclesonide and its active metabolite desisobutyryl-ciclesonide is low after intranasal administration. High protein binding (approximately 99%) and rapid first-pass clearance further reduce systemic exposure to the drug. In well designed trials, intranasal ciclesonide 200 microg once daily for 2-4 weeks was more effective than placebo in terms of improving nasal symptoms in adolescents and adults with moderate to severe seasonal allergic rhinitis. Quality of life measures were statistically significantly improved in ciclesonide relative to placebo recipients during the first 2 weeks of therapy. Similarly, in adolescents and adults with moderately severe perennial allergic rhinitis, ciclesonide 200 microg once daily was more effective than placebo in terms of reducing nasal symptoms in well designed trials of 6 weeks' and 1 year's duration. Improvements relative to placebo in quality of life measures were not considered clinically relevant. Ciclesonide nasal spray was generally well tolerated in these clinical trials; most adverse events were mild to moderate in intensity.

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.. 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).. 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.. 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.. 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.

Ciclesonide is an intranasal corticosteroid approved for the treatment of allergic rhinitis (AR).. To evaluate the time to onset of action of ciclesonide, 200 microg/d, in patients with seasonal AR (SAR).. In a double-blind, randomized, placebo-controlled study conducted in an environmental exposure chamber, 509 adults with at least a 2-year history of SAR completed 1 to 5 priming sessions of ragweed pollen exposure (mean [SD] of 3,500 [500] grains/m3). Patients with successful priming visits (defined as patient-assessed instantaneous total nasal symptom scores [TNSSs] > or =6 and rhinorrhea or nasal congestion scores -2) received a single dose of intranasal ciclesonide, 200 microg (n = 255), or placebo (n = 254). The difference in the change from baseline in TNSSs between the ciclesonide and placebo groups was measured hourly 1 to 12 hours after study drug administration.. At hour 6, the mean treatment difference in TNSSs between ciclesonide and placebo was 0.53 (95% confidence interval, 0.03-1.03; P = .02). Significant treatment differences in favor of ciclesonide were also observed at 2 additional time points: hour 10 (P = .01) and hour 12 (P = .008).. These results confirm that intranasal ciclesonide, 200 microg/d, has an onset of action of 6 hours in patients with SAR.

Aerosol-based corticosteroid nasal formulations may be preferred over current aqueous nasal sprays by some patients because they traditionally cause less pharyngeal and anterior nose runoff.. To determine the optimal dose, safety, and tolerability of ciclesonide hydrofluoroalkane nasal aerosol in patients with seasonal allergic rhinitis (SAR).. Patients 12 years or older with a history of SAR received ciclesonide hydrofluoroalkane nasal aerosol to a total dose of 75, 150, or 300 microg or placebo once daily (half dose per nostril) for 2 weeks. The primary efficacy assessment was patient-reported average morning and evening reflective (24-hour) total nasal symptom scores (rTNSS). Secondary efficacy assessments included patient-reported average morning and evening instantaneous TNSS (iTNSS), patient-reported morning iTNSS, physician-assessed nasal signs and symptom severity, and Rhinoconjunctivitis Quality of Life Questionnaire responses. Safety and tolerability were also assessed.. Ciclesonide hydrofluoroalkane nasal aerosol demonstrated a statistically significantly greater reduction from baseline in average morning and evening rTNSS (24-hour) vs placebo, with treatment differences as follows: 0.81 (P = .001; 300 microg), 0.90 (P < .001; 150 microg), and 0.66 (P = .01; 75 microg). Improvements in average morning and evening iTNSS and patient-reported morning iTNSS were also significantly improved regardless of dose (P < or = .003 for all ciclesonide groups vs placebo). The incidence of treatment-related adverse events was low (< 1.6% for all) and similar among groups.. Ciclesonide hydrofluoroalkane nasal aerosol demonstrated statistically significant improvements in SAR symptoms vs placebo. On the basis of comparable efficacy and safety profiles observed for all doses, these results suggest that the 75-microg and 150-microg doses of ciclesonide hydrofluoroalkane appear appropriate for further evaluation of efficacy.

Ciclesonide is an intranasal corticosteroid approved for the treatment of allergic rhinitis. We conducted a randomized, double-blind, parallel-group, placebo-controlled study to evaluate the time to onset of action of ciclesonide 200 microg once daily in 502 adults with seasonal allergic rhinitis of at least 2 years' duration. To trigger immunologic priming, patients underwent between one and five priming sessions with exposure to 3,500 grains/m(3) (+/-500) of ragweed pollen in an environmental exposure chamber. The criteria for a successful priming session were a patient-assessed instantaneous total nasal symptom score of at least 6 (of a possible 12) and a nasal congestion or rhinorrhea score of at least 2 (of a possible 3) 90 minutes after allergen exposure during at least two consecutive priming sessions. Patients were then randomly assigned to receive either a single dose of ciclesonide 200 microg (n = 251) or placebo (n = 251) administered intranasally. The difference in the change from baseline total nasal symptom scores in the two groups was assessed hourly for 12 hours after administration. Onset of action was determined to have taken place the first time that the effects of ciclesonide, as reflected in the total nasal symptom score, were significantly greater than those of placebo at a particular hourly assessment, provided that the subsequent hourly assessment also showed a statistically significant difference. The onset of action of ciclesonide occurred within 1 hour of administration (p = 0.01 vs. placebo), and the significant difference in total nasal symptom scores between ciclesonide and placebo was maintained through post-treatment hour 12 (p = 0.018).

Ciclesonide is an intranasal corticosteroid in development for the treatment of allergic rhinitis. To assess the safety, tolerability, and pharmacokinetics of ciclesonide, adult healthy volunteers and asymptomatic subjects with seasonal allergic rhinitis were randomized to receive intranasal ciclesonide or placebo for 14 days. Serum concentrations of ciclesonide and its active metabolite, desisobutyryl-ciclesonide, were measured using high-performance liquid chromatography assay with tandem mass spectrometric detection, with lower limits of quantification of 25 and 10 pg/mL, respectively. Adrenal function was monitored by diurnal serum free and 24-hour urine cortisol concentrations. Despite the use of a sensitive assay and a high ciclesonide dose (800 microg/d), serum levels of ciclesonide and desisobutyryl-ciclesonide were below the lower limits of quantification for the majority of samples assayed. Ciclesonide was well tolerated and did not appear to affect serum or urine free cortisol levels. The low systemic exposure and favorable safety profile support the continued clinical development of ciclesonide nasal spray.

Allergic rhinitis (AR), an inflammatory disease of the nasal mucosa, affects approximately 25% of adults and 40% of children in the United States. Ciclesonide nasal spray is a corticosteroid being developed as a hypotonic formulation for AR.. We sought to evaluate the efficacy, safety, and tolerability of ciclesonide nasal spray in adult and adolescent patients with seasonal AR (SAR).. In this double-blind study patients (age, >or=12 years) were randomized to receive 200 microg of intranasal ciclesonide (n = 164) or placebo (n = 163) once daily for 28 days. The primary measure was morning and evening patient-assessed reflective total nasal symptom score (TNSS). Additionally, instantaneous TNSSs, physician-assessed overall nasal signs and symptoms severity, and the results of the Rhinoconjunctivitis Quality of Life Questionnaire were evaluated. Adverse events were monitored throughout the study.. Ciclesonide significantly improved average morning and evening reflective and instantaneous TNSSs compared with placebo over days 1 to 14 (P < .001). Improvements were also noted over days 1 to 28 (P < .001) and over days 15 to 28 (P = .011). Ciclesonide was well tolerated.. Intranasal ciclesonide was superior to placebo in relieving nasal symptoms in adult and adolescent patients with SAR. These results confirm the dose range-finding study in patients with SAR and support the efficacy of ciclesonide in AR.. In a clinical setting ciclesonide was shown to be safe and effective in the treatment of SAR in adolescent and adult patients.

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.. To evaluate the dose-dependent efficacy and safety of a hypotonic intranasal formulation of ciclesonide in patients with seasonal allergic rhinitis (SAR).. 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.. 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.. 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.

Various minimal clinically important difference (MCID) threshold estimation techniques have been applied to seasonal allergic rhinitis (SAR). The objectives of this study are to (i) assess the difference in magnitude of alternative SAR MCID threshold estimates and (ii) evaluate the impact of alternative MCID estimates on health technology assessment (HTA).. Data describing change from baseline of the reflective Total Nasal Symptom Score (rTNSS) for four intranasal SAR treatments were obtained from United States Food and Drug Administration-approved prescribing information. Treatment effects were then compared with anchor-based MCID thresholds derived by Barnes et al. and thresholds obtained from an Agency for Healthcare Research and Quality (AHRQ) panel.. The change in rTNSS score from baseline, represented as the average of the twice-daily recorded scores of the rTNSS, was -2.1 (p < .001) for azelastine hydrochloride 0.10%, 1.35 (p = .014) for ciclesonide, and -1.47 (p < .001) for fluticasone furoate. The change in the rTNSS score from baseline, represented by sum of the AM and PM score, was -2.7 for MP-AzeFlu (p < .001). The rTNSS change from baseline for each product was compared with anchor-based MCID threshold and the AHRQ panel estimates. Comparison of the observed treatment effect to the anchor-based and AHRQ panel MCID thresholds results in different conclusions, with clinically important differences being inferred when anchor-based estimates serve as the reference point.. The AHRQ panel MCID threshold for the rTNSS was twelve times larger than the anchor-based estimates resulting in conflicting recommendations on whether different SAR treatments provide clinically meaningful benefit.

Ciclesonide, a new corticosteroid for allergic rhinitis, is administered as an inactive parent compound that is converted by esterases to the pharmacologically active metabolite, desisobutyryl-ciclesonide (des-CIC). This study investigated the in vitro activation of ciclesonide in nasal mucosa of multiple animal species. Nasal mucosal homogenates from rats, guinea-pigs, rabbits and dogs were incubated with ciclesonide 0.5 micromol/l (0.271 microg/ml) or 5 micromol/l (2.71 microg/ml) for up to 120 min. Concentrations of ciclesonide and des-CIC were measured by high-performance liquid chromatography with tandem mass spectrometry. Ciclesonide was metabolized to des-CIC in nasal mucosal homogenates of each species. The initial velocities of des-CIC formation ranged from 0.0038 to 0.0150 nmol/min/mg protein and 0.0319 to 0.0983 nmol/min/mg protein in nasal mucosal homogenates incubated with ciclesonide 0.5 micromol/l and 5 micromol/l, respectively. Furthermore, the initial velocities of ciclesonide metabolism ranged from 0.0032 to 0.0142 nmol/min/mg protein and 0.0445 to 0.1316 nmol/min/mg protein in nasal mucosal homogenates incubated with ciclesonide 0.5 micromol/l and 5 micromol/l, respectively. This study confirms that ciclesonide is converted to des-CIC in nasal mucosal homogenates without any marked differences among animal species.
