RESUMO

BACKGROUND: Mometasone furoate (MF) is a new inhaled glucocorticoid administered by dry powder inhaler (DPI). OBJECTIVE: MF-DPI was evaluated for safety and efficacy and compared with placebo DPI and beclomethasone dipropionate (BDP) administered by metered dose inhaler (MDI) in the treatment of patients with moderate persistent asthma. METHODS: Eligible patients (n = 227), 13 to 75 years of age, maintained on inhaled glucocorticoids before entering the trial, were randomized to receive: MF-DPI, 100 microg, twice daily, MF-DPI, 200 microg, twice daily, BDP MDI, 168 microg, twice daily, or placebo in a 12-week, multicenter, double-blind study. RESULTS: At endpoint, FEV1 (primary efficacy variable) significantly improved for all three active treatments compared with placebo (P < .01, all comparisons). The response to MF-DPI, 200 microg, twice daily treatment was approximately twice as large as the response to MF-DPI, 100 microg, twice daily or BDP MDI treatment, although the differences between these groups did not reach statistical significance. Secondary efficacy variables including PEFR, asthma symptoms, nocturnal awakenings, and albuterol use showed similar trends. The MF-DPI, 100 microg, twice daily and BDP MDI, 168 microg, twice daily treatment groups produced comparable results for all efficacy variables. CONCLUSIONS: MF-DPI, 100 microg and 200 microg, twice daily were well-tolerated and significantly improved lung function and symptom control in the treatment of patients with moderate persistent asthma. In this study, MF-DPI, 200 microg, twice daily seemed to be the most effective dosage.

RESUMO

BACKGROUND: Once-daily dosing with an effective inhaled corticosteroid (ICS) would likely enhance compliance and, therefore, aid in the management of asthma. OBJECTIVE: Several once-daily dosing regimens of mometasone furoate (MF) administered by dry powder inhaler (DPI) were compared with a twice-daily dosing regimen in 286 patients with mild to moderate persistent asthma who were previously being treated with ICS. METHODS: During a 2-week open-label phase, patients received MF-DPI, 200 microg twice daily. They were then randomized to continue MF-DPI, 200 microg twice-daily treatment or to receive MF-DPI, 200 microg once daily in the morning (AM), 200 microg once daily in the evening (PM), 400 microg once daily AM, or placebo as part of the 12-week, double-blind phase. The primary efficacy variable was the mean change from the baseline to endpoint (last evaluable observation) for FEV1. RESULTS: Once-daily MF-DPI, 400 microg, AM maintained FEV1, and morning peak expiratory flow rate, FVC, FEF25%-75%, and asthma symptom scores, at levels similar to those for MF-DPI, 200 microg twice daily and significantly better than placebo. Once-daily MF-DPI, 200 microg, PM was effective in maintaining pulmonary function, but was less effective on other efficacy measures. In comparison to the other MF-DPI groups, once-daily MF-DPI, 200 microg, AM was not as effective overall. The incidence of local adverse events, including oral candidiasis, was low with all dosages. CONCLUSIONS: Once-daily MF-DPI, 400 microg, AM was as effective as MF-DPI, 200 microg twice daily, whereas once-daily MF-DPI, 200 microg, was more effective when administered in the evening compared with morning, for patients receiving ICS therapy. Once-daily dosing offers an effective and convenient treatment that could aid compliance in the treatment of asthma.

RESUMO

BACKGROUND: Inhaled corticosteroid therapy in severe persistent asthma has been shown to reduce or eliminate oral corticosteroid (OCS) use while retaining effective asthma control. OBJECTIVE: We sought to evaluate the ability of mometasone furoate (MF) delivered by means of dry powder inhaler to reduce daily oral prednisone requirements in OCS-dependent patients with severe persistent asthma. METHODS: We performed a 12-week, double-blind, placebocontrolled trial (21 centers, 132 patients) comparing 2 doses of MF (400 and 800 microg administered twice daily) with placebo, followed by a 9-month open-label phase in which 128 patients received treatment with MF. RESULTS: At the endpoint of the double-blind trial, MF 400 and 800 mg twice daily reduced daily OCS requirements by 46.0% and 23.9%, respectively, whereas placebo increased OCS requirements by 164.4% (P <.01). Oral steroids were eliminated in 40%, 37%, and 0% of patients in the MF 400 and 800 mg twice daily and placebo groups, respectively. Pulmonary function and quality of life significantly increased for MF-treated patients. Further reductions in OCS requirements were achieved with long-term MF treatment in the open-label phase. CONCLUSION: MF inhaled orally as a dry powder is an effective alternative to systemic corticosteroids in patients with severe persistent asthma.

RESUMO

BACKGROUND: Despite current recommendations, many patients with persistent asthma are still treated with bronchodilators alone. OBJECTIVE: The safety and efficacy of two once daily dosing regimens (200 microg and 400 microg) of mometasone furoate (MF) administered in the morning by using a dry-powder inhaler (DPI) were compared with those of a twice daily dosing regimen (200 microg administered twice daily) in patients with mild-to-moderate persistent asthma previously taking only inhaled beta(2)-adrenergic agonists. METHODS: All patients (306 patients; age range, 12-70 years) were given a diagnosis of asthma for at least 6 months before enrollment in this 12-week, placebo-controlled, double-blind, randomized study. The primary efficacy variable was change in FEV(1) from baseline to endpoint (last evaluable visit). RESULTS: At endpoint, FEV(1) was significantly improved (P < or =.02) after MF-DPI 400 microg once daily morning treatment and MF-DPI 200 microg twice daily treatment (16.0% and 16.1%, respectively) compared with placebo (5.5%). The improvement seen with MF-DPI 200 microg once daily morning treatment (10.4%) was not significantly different from that with placebo. Secondary efficacy variables also showed significant improvement for the MF-DPI 400 microg once daily morning treatment group and the MF-DPI 200 microg twice daily treatment group compared with the placebo group. All doses of MF administered by means of a DPI were well tolerated. CONCLUSION: This is the first study to demonstrate that a total daily dose of 400 microg of MF administered by means of a DPI is an effective treatment for patients with mild-to-moderate persistent asthma previously taking only inhaled beta(2)-adrenergic agonists. This treatment was equally effective when administered either as a once daily or twice daily regimen.

RESUMO

BACKGROUND: Although inhaled glucocorticoids are recommended for all stages of persistent asthma, compliance with long-term therapy is often poor, leading to significant morbidity and mortality. A simplified, once-daily dosing regimen may foster improved compliance. OBJECTIVE: To compare the efficacy and safety of once-daily (AM) administration of mometasone furoate dry powder inhaler (MF DPI) 200 microg and 400 microg with placebo in patients with asthma previously maintained only on short-acting inhaled beta-adrenergic receptor agonists. METHODS: This was a 12-week, double-blind, placebo-controlled, parallel group study. The mean change from baseline to endpoint (last treatment visit) for FEV1 was the primary efficacy variable. RESULTS: At endpoint, both doses of MF DPI were significantly more effective than placebo (P < or = .05) in improving FEV1. Based on morning peak expiratory flow rate, once-daily MF DPI 400 microg was more effective than placebo (P < or = .001) at endpoint. Both active treatments also demonstrated improvement at endpoint in asthma symptom scores, physician-evaluated response to therapy and use of rescue medication. Although both MF DPI dosages were efficacious, MF DPI 400 microg provided additional improvement in some measures of pulmonary function (eg, morning PEFR) when these agents were administered once daily in the morning. Both doses of MF DPI were well tolerated and treatment-related adverse events occurred at a similar incidence among the three treatment groups. CONCLUSIONS: The results of this study indicate that once-daily (AM) MF DPI provides a convenient and effective treatment option for patients with mild or moderate persistent asthma.

RESUMO

OBJECTIVE: Intranasal corticosteroids are used widely for the treatment of allergic rhinitis because they are effective and well tolerated. However, their potential to suppress growth of pediatric subjects with allergic rhinitis continues to be a concern, particularly in light of reports of growth suppression after treatment with intranasal beclomethasone dipropionate or intranasal budesonide (see the article by Skoner et al in this month's issue). A 1-year study of prepubertal patients between 3 and 9 years of age with perennial allergic rhinitis was conducted to assess the effects on growth of mometasone furoate aqueous nasal spray (MFNS), a new once-daily (QD) intranasal corticosteroid with negligible bioavailability. METHODS: This was a randomized, placebo-controlled, double-blind, multicenter study. Ninety-eight subjects were randomized to treatment with either MFNS 100 microg QD or placebo for 1 year. Each subject's height was required to be between the 5th and 95th percentile at baseline, and skeletal age at screening was required to be within 2 years of chronological age, as determined by left wrist x-rays. Washout periods for medications that affect either childhood growth or allergic rhinitis symptoms were established based on estimated period of effect, and these medications were prohibited during the study. However, short courses of either oral prednisone lasting no longer than 7 days or low-potency topical dermatologic corticosteroids lasting no longer than 10 days were permitted if necessary. Height was measured with a calibrated stadiometer at baseline and at 4, 8, 12, 26, 39, and 52 weeks, and the primary safety variable was the change in standing height. The rate of growth was also calculated for each subject as the slope (linear regression) of the change in height from baseline using data from all visits of subjects who had at least 2 visits. Hypothalamic-pituitary-adrenocortical- (HPA)-axis function was assessed via cosyntropin stimulation testing at baseline and at 26 and 52 weeks. All analyses were based on all randomized subjects (intent-to-treat principle). The change from baseline in standing height was analyzed by a 2-way analysis of variance that extracted sources of variation attributable to treatment, center, and treatment-by-center interaction. RESULTS: Demographic characteristics were similar at baseline. Eighty-two subjects completed the study (42 in the MFNS group and 40 in the placebo group), and 93% of subjects achieved at least 80% compliance with therapy. After 1 year of treatment, no suppression of growth was seen in subjects treated with MFNS, and mean standing heights were similar for both treatment groups at all time points. For the primary safety variable (change in height from baseline), both treatment groups were similar at all time points except for weeks 8 and 52. Subjects treated with MFNS had a slightly greater mean increase in height than subjects treated with placebo at these time points: the change in height was 6.95 cm versus 6.35 cm at the 1-year time point. However, the rate of growth (.018 cm/day) averaged for all time points over the course of the study was similar for both treatment groups. Additional analyses found that MFNS did not retard growth in any sex or age subgroup of subjects. The use of exogenous corticosteroids other than the study drug was also similar among the 2 treatment groups. Results from cosyntropin stimulation testing confirmed the absence of systemic effects of MFNS. The change from baseline in the difference between prestimulation and poststimulation levels was similar for both treatment groups after 1 year of treatment, with no evidence of HPA-axis suppression in MFNS-treated subjects at any time point. Incidences of treatment-related adverse events were similar for both treatment groups, with 16% of MFNS-treated subjects reporting adverse events, compared with 22% of placebo-treated subjects. CONCLUSIONS: (ABSTRACT TRUNCATED)

RESUMO

Mometasone furoate (MF) administered by dry powder inhaler (DPI) was composed with budesonide (BUD) Turbuhaler in the treatment of moderate persistent asthma. The patients were randomized to one of four treatment groups: MF DPI (100, 200, 400 microg b.i.d) or BUD Turbuhaler. 400 microg b.i.d in a 12-week, active-controlled, evaluator-blind, multicentre international trial. The primary efficacy variable was the mean change from baseline to endpoint (last treatment visit) in forced expiratory volume in one second (FEV1). Changes in FEV1 showed a statistically significant superiority (p<0.05) of MF DPI 200 and 400 microg b.i.d compared with the BUD Turbuhaler 400 microg b.i.d treatment. Significant superiority (p<0.05) was also seen in scores for several secondary efficacy variables when MF DPI was compared with BUD Turbuhaler treatment. MF DPI 200 microg b.i.d was comparable to MF DPI 400 microg b.i.d in therapeutic benefit. The incidence of oral candidiasis was no more than 3% in any group. All treatments were well tolerated. A total daily dose of 400 microg of mometasone furoate administered by dry powder inhaler provides a well-tolerated treatment for patients with moderate persistent asthma and results in a significantly greater improvement, when compared to a daily dose of 800 microg BUD Turbuhaler in the parameters measured in this study.

RESUMO

A new formulation of mometasone furoate (MF) for administration by dry powder inhaler (DPI) was evaluated for the treatment of asthma. A 12-week, double-blind, placebo-controlled dose-ranging study compared the efficacy and safety of three doses of MF DPI (100, 200 and 400 mcg b.i.d) with beclomethasone dipropionate (BDP) 168 mcg b.i.d. administered by metered dose inhaler in 365 adult or adolescent patients being treated with inhaled glucocorticoids. The mean change from baseline to endpoint (last treatment visit) for forced expiratory volume in 1 sec (FEV1) was the primary efficacy variable. Secondary efficacy variables included other objective measures of pulmonary function [forced vital capacity (FVC), forced expiratory flow 25-75% (FEV25-75%.) and peak expiratory flow rate (PEFR)] as well as subjective measures of therapeutic response (patients' daily evaluation of asthma symptoms and physicians' evaluation). At endpoint, all four active treatments were significantly more effective than placebo (P < 0.01) in improving FEV1 (MF DPI 5 to 7%, BDP 3%, placebo -6.6%) and all other measures of pulmonary function (FVC: MF DPI 4 to 5%, BDP 2%, placebo -4.7%; FEF25-75%: MF DPI 6 to 18%, BDP 7.5%, placebo -9.5%; PEFR (AM): MF DPI 5 to 10%, BDP 5.7%, placebo -7%). A consistent trend was observed for better improvement in patients treated with MF DPI 200 mcg b.i.d. than with MF DPI 100 mcg b.i.d., with no apparent additional benefit of MF DPI 400 mcg b.i.d. Results for the MF DPI 100 mcg b.i.d. and BDP 168 mcg b.i.d. treatment groups were similar. Patients' and physicians' subjective evaluations of symptoms found similar improvement in the MF DPI 200 and 400 mcg b.i.d. treatment groups, which were slightly better than that in the MF DPI 100 mcg b.i.d. group. Symptoms tended to worsen in the placebo group. MF DPI was well tolerated at all dose levels and the most frequently reported treatment-related adverse effects were headache, pharyngitis and oral candidiasis. No evidence of HPA-axis suppression was detected in any treatment group. In summary, all doses of MF DPI were well tolerated and significantly improved lung function and MF DPI 400 mcg (200 mcg b.i.d.) was the optimal dose in this study of patients with moderate persistent asthma.

RESUMO

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

RESUMO

BACKGROUND: Mometasone furoate nasal spray (MFNS, NASONEX ), is a new synthetic corticosteroid with considerable efficacy in the treatment of seasonal and perennial rhinitis and less than 0.1% systemic absorption. This study was designed to evaluate the time of onset of action of MFNS. The subjects were evaluated over the course of 2 weeks during the spring allergy season. METHODS: The effects of MFNS 200 microg given once daily for 2 weeks were evaluated in a randomized, multicenter, double-blind, placebo-controlled study in 201 patients with seasonal allergic rhinitis. Clinically significant onset of action was assessed prospectively by special patient diary cards kept during the first 3 days of treatment. RESULTS: By 12 h after initial dosage (the earliest evaluation), 28% of patients in the MFNS group experienced clinically significant relief, compared with 13% of those given placebo (P = 0.01). Median time to at least moderate symptom relief in patients who received MFNS was 35.9 h, compared with more than 72 h in patients given placebo (P<0.01). By 72 h, 64% of the patients receiving MFNS experienced at least moderate relief, compared with 40% of those treated with placebo (P<0.01). Both patient and physician ratings of symptom severity, response to treatment, and overall condition of rhinitis indicated significant (P<0.01) superiority of MFNS over placebo. MFNS was well tolerated, with adverse events comparable to placebo. CONCLUSIONS: MFNS provided rapid onset of clinically significant symptom relief in patients with seasonal allergic rhinitis.

RESUMO

BACKGROUND: Mometasone furoate is a potent glucocorticoid that can markedly inhibit proinflammatory Th2 cytokines in vitro. An aqueous nasal spray formulation has been shown to be clinically active in reducing the symptoms of perennial and seasonal allergic rhinitis. OBJECTIVE: To determine whether pretreatment with mometasone furoate 200 microg once daily decreases specific indices of early and late phase nasal inflammation compared with placebo. METHODS: A randomized, double-blind, placebo-controlled crossover study was conducted using nasal provocation with ragweed antigen in 21 patients with ragweed-induced allergic rhinitis out of the ragweed season; the treatment period was 2 weeks. Symptom scores, rhinoprobe cytology, and nasal lavage fluid were collected during early and late phase periods for nasal cytokines (interleukin, 1, 4, 5, 6, and 8) and leukotriene B4 determinations using ELISA and RIA. RESULTS: Mean nasal symptom scores and sneezing frequency were consistently lower with mometasone furoate compared with placebo. Treatment was associated with a statistically significant early phase (30-minute time point) reduction in nasal lavage histamine levels compared with placebo (14.3 versus 20.2 ng/mL, P = .02). Within-treatment comparisons suggested that mometasone furoate reduced the antigen-induced late-phase response for IL-6, IL-8, and eosinophils compared with pretreatment. There were similar, but smaller, changes seen in the placebo group for these measurements. There were no statistically significant changes following antigen challenge in IL-1, IL-4, IL-5, LTB4, or in other nasal cytology parameters. CONCLUSION: These results suggest that the clinical activity of mometasone furoate nasal spray in seasonal allergic rhinitis is likely due, in part, to a reduction in the levels of histamine in nasal secretions related to the early phase response, and reductions in IL-6, IL-8, and eosinophils during the late phase response.

RESUMO

Allergic rhinitis is associated with specific histopathologic changes in the nasal mucosa including squamous metaplasia and local eosinophilia. Previous studies have shown that mometasone furoate aqueous nasal spray is effective and well tolerated in reducing perennial rhinitis and seasonal allergic rhinitis symptoms. We undertook a multicenter, open-label study to evaluate, by nasal biopsy, the tissue changes associated with mometasone furoate use (200 microg/day) during a 12-month treatment period in patients with perennial rhinitis. Of the 69 patients enrolled in the study, 52 completed all 12 months of treatment. Nasal biopsy specimens obtained from patients at baseline and after treatment were evaluated in a blinded fashion by computerized image analysis, qualitative histologic examination, and immunocytochemistry. Morphologic examination of nasal biopsy specimens showed a decrease in focal metaplasia, no change in epithelial thickness, and no sign of atrophy after treatment with mometasone furoate. Immunocytochemical analyses of nasal biopsy specimens obtained before and after treatment revealed a significant decrease in major basic protein-positive eosinophils and tryptase-positive mast cells in the epithelium and lamina propria after treatment. Mometasone furoate appeared to attenuate the inflammatory process by reducing the extent of inflammatory cell infiltration, particularly of eosinophils. This study demonstrated that long-term administration of mometasone furoate is not associated with adverse tissue changes in the nasal mucosa of patients with perennial rhinitis.

RESUMO

The objective of the study was to compare the validity of asthma-specific and generic health outcome measures in relation to changes in the severity of asthma and to treatment. Adult patients (n = 142) participating in a randomized placebo-controlled trial at six clinics were assessed at baseline, prior to the withdrawal (placebo) or continuation of treatment with Vanceril and again after 8 weeks. The criterion measures of change in severity included pulmonary function expressed as the percent predicted FEV1, five physician-assessed asthma severity measures (cough, chest tightness, wheezing, shortness of breath and overall condition) and two patient-assessed severity measures (night-time symptoms and overall symptoms). The 8 week change scores were estimated for all generic and specific measures and the results were compared across groups of patients who did and did not change in terms of clinical criteria of disease severity and across treatment groups. The responsiveness of each generic and specific measure was estimated independently using the relative validity (RV) methodology, which compares F-ratios for the mean change scores across measures in analyses of the same comparison groups. RV coefficients estimate how much worse each measure discriminated between comparison groups, relative to the best measure (RV = 1.0). Four standardized asthma-specific measures and a total scale score (based on the Marks questionnaire), an individualized asthma-specific scale measuring limitations in activities most important to each patient (based on the Juniper method) and two newly-developed scales measuring physical and psychosocial symptoms were used as outcome measures, generic health outcome measures included eight functional health and well-being scales as well as the physical and mental health summary scales from the SF-36 health survey. A standardized asthma-specific scale was most valid in discriminating between groups of patients who did and did not change according to all of the clinical criterion variables studied and in discriminating between treated and untreated groups. Different scales performed best, depending on the clinical criterion. The asthma-specific Marks breathlessness scale was significant in all nine comparisons (RV = 0.62-1.0) and was most valid in discriminating between groups in six of nine tests. The overall scale also performed well in all comparisons (RV = 0.58-1.0). The newly-developed physical symptoms scale was significant in discriminating between groups in eight out of nine tests (RV = 0.52-1.0) and was most valid in three of the nine, including the treatment comparison. The psychosocial impact scale discriminated significantly in eight of the nine comparisons (RV = 0.16-0.38), but was less valid than other specific measures. The asthma-specific individualized activities scale discriminated significantly in seven of the nine tests, but performed less well than the other specific measures (RV = 0.21-0.35) and was not significant in the treatment comparison. One or more SF-36 scales discriminated significantly between groups in all nine comparisons. Two of those scales (physical functioning and role-physical) were consistently more valid than the others (RV = 0.17 and 0.58, respectively) and were the only two generic scales that discriminated between groups of patients defined in terms of changes in FEV1 (RV = 0.26-0.58). The SF-36 physical summary scale discriminated significantly between groups in all nine comparisons (RV = 0.19-0.61) and was the most valid generic measure in the treatment comparison (RV = 0.55). The SF-36 mental summary scale was significant only for the two patient-assessed changes in disease severity (RV = 0.31 and 0.32) and for physician-assessed overall severity (RV = 0.12). A comprehensive battery of generic and specific measures is likely to be most useful in understanding the impact of changes in disease severity on the functional health and well-being of adults with asthma, a

RESUMO

BACKGROUND: Mometasone furoate (Nasonex), in a new once-daily aqueous nasal spray formulation, has been shown to be as effective and well-tolerated as twice-daily beclomethasone dipropionate aqueous nasal spray in treating symptoms of seasonal allergic rhinitis and perennial rhinitis. OBJECTIVE: To compare the effectiveness and tolerability of mometasone furoate to placebo and of fluticasone propionate aqueous nasal spray, all treatments administered once-daily, in patients with perennial rhinitis. METHODS: This was a 3-month, randomized, double-blind, double dummy, parallel group study in 550 patients, aged 12 to 77 years, at 25 centers in Canada, Latin America, and Europe. Patients allergic to at least one perennial allergen, with confirmed allergy history, skin test positivity, and moderate to severe symptomatology, were eligible to receive one of the following treatments, once daily in the morning: mometasone furoate 200 micrograms, fluticasone propionate 200 micrograms, or placebo. The primary efficacy variable was the change from baseline in total AM plus PM diary nasal symptom score over the first 15 days of treatment. RESULTS: Four hundred fifty-nine patients were valid for efficacy. For the primary efficacy variable, mometasone furoate was significantly (P < .01) more effective than placebo and was not statistically different from fluticasone propionate (percent reductions from baseline were 37, 39, and 22 for mometasone furoate, fluticasone propionate, and placebo, respectively). Generally, similar trends were seen for physician-evaluated total nasal symptoms, and patient-rated and physician-rated overall condition and response to therapy. Overall, mometasone furoate was at least as effective as fluticasone propionate at equivalent doses. There was no evidence of tachyphylaxis. All treatments were well tolerated. CONCLUSION: Mometasone furoate and fluticasone propionate adequately controlled symptoms of perennial rhinitis and were well tolerated.

RESUMO

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.

RESUMO

STUDY OBJECTIVE: To compare the efficacy and safety of a double-strength formulation of beclomethasone dipropionate (BDP 84) metered-dose inhaler (MDI) with that of beclomethasone dipropionate (BDP 42) MDI in the treatment of chronic asthma. DESIGN: A 28-day, randomized, double-blind, double-dummy, placebo-controlled, multicenter study. SETTING: Outpatient. PATIENTS: A total of 423 patients aged 12 to 65 years (mean range, 34 to 36 years) with moderate asthma (FEV1, 50 to 80% of predicted) who required long-term inhaled corticosteroids were enrolled. INTERVENTIONS: Patients were randomized to receive BDP 84, two oral inhalations bid (336 microg/d), BDP 42, four oral inhalations bid (336 microg/d), or placebo. A fourth treatment arm administering BDP 84, eight oral inhalations bid (HD BDP 84; 1,344 microg/d) was also included to determine whether a dose-response relationship could be demonstrated. MEASUREMENTS: Spirometry, clinical observations. RESULTS: The three active treatments were significantly more effective (p < or = 0.01) than placebo at all time points in improving FEV1, the primary efficacy parameter; BDP 42 and BDP 84 were comparable to each other at every time point. Secondary pulmonary function tests (FVC, forced expiratory flow at 25 to 75% of FVC, and peak expiratory flow rate) showed similar results. All three active treatments were well tolerated. A dose response between 336 microg/d and 1,344 microg/d was demonstrated. CONCLUSION: In this well-controlled 28-day study, BDP 42 and BDP 84 were shown to be comparable in efficacy and safety on a microgram-for-microgram basis.

RESUMO

BACKGROUND: Topical nasal corticosteroids have become a mainstay of treatment for the symptoms of seasonal allergic rhinitis (SAR). It is likely that topical corticosteroids, by blocking an initial influx of inflammatory cells in the nasal mucosa induced by aeroallergens, may have a preventive effect on nasal allergy symptoms when administered before the pollen season. OBJECTIVE: This study was designed to assess the efficacy and safety of an 8-week course of mometasone furoate nasal spray (MFNS), 200 micrograms once daily, in the treatment of SAR compared with beclomethasone dipropionate aqueous nasal spray (BDP), 168 micrograms twice daily, and placebo vehicle, when treatment is initiated before the anticipated onset of the ragweed season. METHODS: Three hundred forty-nine patients with SAR to ragweed pollen from nine centers in the Northeast and Midwest of the United States were randomized to one of the three intranasal study medications (MFNS, 200 micrograms once daily, BDP, 168 micrograms twice daily, or placebo vehicle), starting 4 weeks before the estimated start of the ragweed season. RESULTS: The proportion of "minimal symptom" days (total nasal symptom score < or = 2) was statistically significantly higher in both the MFNS and BDP groups when compared with the placebo vehicle group (p < 0.01). The two active treatment groups were not statistically significantly different from each other. MFNS and BDP displayed a similar safety profile that did not differ from placebo. CONCLUSIONS: This suggests that MFNS, 200 micrograms (once daily), is a useful therapy in the prophylactic treatment of SAR.

RESUMO

Mometasone furoate aqueous nasal spray (Nasonex) was compared with beclomethasone dipropionate (BDP) aqueous nasal spray in a double-blind, randomized, placebo-controlled, double-dummy, parallel-group study of adults with moderate to severe seasonal allergic rhinitis. Patients allergic to at least one tree and/or grass aeroallergen received one of the following regimens for up to 4 weeks; mometasone furoate 100 micrograms once daily [OD] (n = 126) or 200 micrograms OD (n = 126), BDP 200 micrograms twice daily (n = 126), or only placebo spray (n = 123). Physician-rated nasal and total symptom scores, and global evaluation of overall condition and therapeutic response by physicians and patients, showed that the three active treatments were equally effective, and all three were significantly superior to placebo at most time points. Overall, mometasone furoate 200 micrograms OD demonstrated somewhat greater numerical, but not statistical, superiority to mometasone furoate 100 micrograms OD at the earliest evaluation time point. At the end of treatment, complete or marked relief was obtained in 77% of patients with mometasone furoate 100 micrograms/day, 79% with mometasone furoate 200 micrograms/day, and 74% with BDP, compared with 54% of placebo vehicle control patients. Mometasone furoate and BDP were equally well tolerated. It was concluded that mometasone furoate adequately controls symptoms of moderate to severe seasonal allergic rhinitis, offers the advantage of OD treatment, and is well tolerated.
