RESUMO

Efficacy and safety of fluticasone furoate nasal spray, administered using a unique side-actuated device, were evaluated in patients > or =12 years of age with seasonal allergic rhinitis to determine the optimal dose. A randomized, double-blind, parallel-group, placebo-controlled, dose-ranging study was performed on 641 patients who received placebo (n=128) or fluticasone furoate, 55 microg (n=127), 110 microg (n=127), 220 microg (n=129), or 440 microg (n=130), once daily for 2 weeks. Fluticasone furoate was significantly more effective than placebo for mean changes from baseline over the 2-week treatment period in daily reflective total nasal symptom score (primary end point; p < 0.001 each dose vs. placebo), morning predose instantaneous total nasal symptom score (p < 0.001 each dose versus placebo), daily reflective total ocular symptom score (p < or = 0.013 each dose versus placebo), and morning predose instantaneous total ocular symptom score (p < or = 0.019 for three highest doses versus placebo). The onset of action for fluticasone furoate nasal spray versus placebo was observed 8 hours after the first. dose of study medication in the 110 and 440 microg treatment groups (p < or = 0.032). The incidence of adverse events, results of clinical laboratory tests, and changes in 24-hour urinary cortisol values were similar between active treatment groups and placebo. The preliminary profile of fluticasone furoate is that of a rapidly effective therapy that confers 24-hour efficacy for both nasal and ocular symptoms with once-daily dosing. The 110-microg dose was chosen for phase III development because it achieved statistically significant and clinically meaningful results for all efficacy end points and provided the optimal risk-benefit ratio.

RESUMO

BACKGROUND: Current asthma guidelines recommend inhaled glucocorticoids administered via pressurized metered-dose inhaler (MDI) with a holding chamber as the preferred therapy for young children with asthma. OBJECTIVE: To evaluate the efficacy and safety of fluticasone propionate chlorofluorocarbon MDI use in preschool-aged children with asthma. METHODS: Randomized, double-blind, placebo-controlled, parallel-group study of 332 children aged 24 to 47 months with asthma. Fluticasone propionate chlorofluorocarbon, 44 or 88 microg twice daily, or placebo (chlorofluorocarbon propellant alone) administered for 12 weeks via MDI with a valved holding chamber and an attached face mask. The primary efficacy measure was average change in 24-hour daily asthma symptom scores. Safety assessments included adverse events, 12-hour urinary cortisol excretion, and growth. RESULTS: Treatment failure (ie, asthma exacerbation) occurred in approximately half as many fluticasone propionate-treated patients (13%-14%) as placebo-treated patients (24%). Compared with placebo users, patients treated with fluticasone propionate, 88 microg twice daily, had a 13% greater improvement in the mean proportion of symptom- and albuterol-free days (P = .02); asthma symptom scores and albuterol use were also significantly reduced. Patients treated with fluticasone propionate, 44 microg twice daily, had greater improvements than placebo-treated patients; however, differences did not reach statistical significance. At end point, the growth velocities of fluticasone propionate-treated patients were within the range of those of placebo-treated patients. No clinically relevant changes in 12-hour overnight urinary cortisol excretion were observed. CONCLUSION: Compared with placebo use, fluticasone propionate, 88 microg administered twice daily, significantly reduced asthma exacerbations, asthma symptoms, and rescue albuterol use and was well tolerated, with no clinically relevant systemic effects, as measured by growth velocity or 12-hour urinary cortisol excretion levels.

RESUMO

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.

RESUMO

Two double-blind, randomized, placebo-controlled, parallel group safety and efficacy studies included evaluation of the hypothalamic-pituitary-adrenal (HPA)-axis effects of concurrent treatment with intranasal and orally inhaled fluticasone propionate (FP). In the first study, patients with asthma who were > or =12 years of age were assigned randomly to receive twice-daily doses (either 88 or 220 microg) of orally inhaled FP delivered from a metered-dose inhaler (MDI). In the second study, patients were assigned randomly to receive either orally inhaled FP 250 microg or orally inhaled FP 250 microg/salmeterol 50 microg delivered via the Diskus device. In both studies, patients with rhinitis were allowed to continue the use of intranasal FP at their usual dosing. Treatment periods were 26 weeks and 12 weeks for the MDI and Diskus studies, respectively. HPA-axis effects were assessed using response to short cosyntropin stimulation testing. The number and percentage of patients with an abnormal cortisol response, defined as a morning plasma cortisol of <5 microg/dL, a poststimulation peak of <18 microg/dL, or a poststimulation rise of <7 microg/dL, were summarized in two subgroups: patients who used intranasal FP and those who did not. The concurrent administration of intranasal FP and orally inhaled FP via an MDI or Diskus or via Diskus with salmeterol was not associated with HPA-axis effects compared with orally inhaled FP alone. The results of these two studies suggest that concurrent use of intranasal FP with orally inhaled FP administered via MDI or Diskus for treatment of comorbid rhinitis and asthma does not increase the risk of HPA-axis abnormalities.

RESUMO

BACKGROUND: The safety and efficacy of intranasal corticosteroids for the treatment of allergic rhinitis is well documented in the literature. Additionally, an expert panel has concluded that intranasal corticosteroids are the first line of therapy when obstruction is a major component of rhinitis. Montelukast is a leukotriene receptor antagonist recently approved for the treatment of seasonal allergic rhinitis (SAR). OBJECTIVE: This randomized, double-blind, double-dummy, parallel-group study was conducted to compare the effectiveness of a 15-day course of intranasal fluticasone propionate 200 microg, once daily (FP200QD), to oral montelukast 10 mg, once daily (MON10QD), in relieving daytime and nighttime nasal symptoms associated with SAR. METHODS: The intent-to-treat (ITT) analysis population consisted of 705 eligible males and females (> or = 15 years) with SAR randomized to either FP200QD (N = 353) or MON10QD (N = 352). The primary efficacy endpoint was the mean change from baseline in subject-rated daytime total nasal symptom scores (the sum of four individual scores: nasal congestion, itching, rhinorrhea, and sneezing), evaluated via visual analog scales, and averaged over weeks 1 to 2. Secondary endpoints included the four daytime individual nasal symptom scores, the nighttime total, and individual nasal symptom scores (each evaluated on a four-point scale from 0 to 3). RESULTS: Statistically significant differences favoring FP200QD over MON10QD were observed for the mean change from baseline in daytime total nasal symptom scores (P < 0.001), daytime individual nasal symptom scores (P < 0.001), nighttime total (P < 0.001), and all individual nasal symptom scores (P < or = 0.002) over the 15-day treatment period. FP200QD and MON10QD were both well tolerated. CONCLUSIONS: The results of this well controlled study demonstrated that FP200QD was consistently superior to MON10QD with regard to every efficacy endpoint evaluated, including daytime and nighttime nasal congestion, in subjects with SAR.

RESUMO

This randomized, double-blind, placebo-controlled study of fluticasone propionate aqueous nasal spray (at a maximum recommended dose of 200 micrograms each day) administered daily for one year was conducted to evaluate its potential effects on growth, measured by stadiometry, in prepubescent children with perennial allergic rhinitis (n = 150; age 3.5 to 9.0 years). The results demonstrate equivalent growth velocity over a one-year treatment period between children receiving fluticasone propionate aqueous nasal spray and children receiving vehicle placebo. In addition, children in both treatment groups had similar increases in height over the same period. Baseline height was 119.1 cm (SE = 0.72) in the fluticasone propionate group (n = 56) and 119.0 cm (SE = 0.71) in the vehicle placebo group (n = 52). Mean height at the end of one year of treatment was 125.5 cm (SE = 0.18) in the fluticasone propionate group (n = 44) and 125.4 cm (SE = 0.19) in the vehicle placebo group (n = 39) (least-squares mean difference -0.12; 95% confidence interval [-0.600, 0.352]). The effects of fluticasone propionate on one-year growth velocity were also comparable to those of vehicle placebo. The confidence interval for the treatment difference lay within the prospectively defined equivalence bounds (of -0.8, +0.8 cm/year) and contained zero. The incidence of adverse events considered to be at least possibly drug-related did not differ between the fluticasone propionate group and the vehicle placebo group. The results of this one-year, double-blind study demonstrate that fluticasone propionate aqueous nasal spray at the maximum recommended dose of two sprays per nostril (200 micrograms) once daily was equivalent to vehicle placebo with no effects on growth rate in prepubescent children.
