Asthma control can be maintained when fluticasone propionate/salmeterol in a single inhaler is stepped down

BACKGROUND: Asthma control is the goal of treatment, but little data exist to support treatment strategies for stepping down treatment once control has been achieved. OBJECTIVE: We assessed whether either the long-acting beta2-agonist or corticosteroid could be reduced without loss of asthma control once control had been attained with fluticasone propionate/salmeterol (FSC). METHODS: After 12 weeks of open-label treatment with FSC 250/50 microg twice daily, patients whose asthma was well controlled were randomized to FSC 100/50 microg twice daily or fluticasone propionate (FP) 250 microg twice daily. for 12 weeks. The primary endpoint was mean morning peak expiratory flow over the randomized study period. Secondary endpoints included symptom scores, rescue albuterol use, and asthma control. RESULTS: During open-label treatment, improvements from baseline were seen, and 435 of 641 patients (68%) achieved well controlled status during each of the last 4 weeks of this period. A total of 246 patients received FSC 100/50 microg twice daily and 238 FP 250 microg twice daily. The adjusted mean change in morning peak expiratory flow from the end of open-label treatment was -0.3 L/min for FSC and -13.2 L/min for FP (treatment difference, 12.9 L/min; 95% CI, 8.1-17.6; P<.001). Secondary efficacy endpoints also showed FSC 100/50 microg twice daily to be more effective than FP 250 microg twice daily alone. The majority of patients remained well controlled, but the proportion was higher with FSC. CONCLUSION: In patients achieving asthma control with FSC 250/50 microg twice daily, stepping treatment down to a lower dose of FSC 100/50 microg twice daily is more effective than switching to an inhaled corticosteroid alone.     

Steroid-sparing effects of fluticasone propionate 100 microg and salmeterol 50 microg administered twice daily in a single product in patients previously controlled with fluticasone propionate 250 microg administered twice daily

BACKGROUND: Concurrent use of an inhaled corticosteroid (ICS) and an inhaled long-acting beta2-agonist provides better overall asthma control than the use of higher doses of ICS alone. OBJECTIVE: The purpose of this investigation was to determine whether fluticasone propionate (FP) combined with salmeterol in the Diskus device can be used to reduce the dose of ICS in patients currently stable on medium-dose ICS while maintaining asthma control. METHODS: This was a randomized, double-blind, parallel-group, 12- to 24-week trial consisting of a 3-part run-in period. The run-in period was designed to first establish FP 250 microg administered twice a day (bid) via Diskus as the minimum effective dose. During run-in period 1, patients received FP 220 microg bid or the equivalent for 10 to 14 days. Controlled patients moved to run-in period 2 (5-28 days), which assessed asthma stability on FP 100 microg bid administered via Diskus. Only patients who became unstable on FP 100 microg bid were eligible to enter run-in period 3 (26-30 days), during which they were placed on FP 250 microg bid and those regaining asthma control were eligible for randomization. The primary efficacy endpoint was the proportion of patients who remained in the study with no evidence of worsening asthma. Secondary efficacy measures included FEV1, morning peak expiratory flow, percent of symptom-free days, and daily albuterol use. RESULTS: Only 5% of patients treated with FP100/salmeterol withdrew because of worsening asthma in the first 12 weeks; this compared with 7% in the FP250 group. All patients from a subset of sites continued in the study for an additional 12 weeks; only an additional 1% of patients treated with either FP100/salmeterol or FP250 withdrew because of worsening asthma. Secondary efficacy measures confirmed primary efficacy results. CONCLUSION: In patients requiring FP250 bid for asthma stability, FP100/salmeterol bid was steroid-sparing, allowing a 60% reduction in the FP dose while maintaining overall asthma control.     

Comparison of once- and twice-daily dosing of fluticasone propionate 200 micrograms per day administered by Diskus device in patients with asthma treated with or without inhaled corticosteroids

Background: There are limited published data regarding the efficacy of once- versus twice-daily administration of flutica-sone propionate. Objective: Our purpose was to evaluate the effectiveness of fluticasone propionate powder 200 μg/d administered as a once- or twice-daily dosage regimen in patients who were currently being treated with bronchodilators only (BD patients) and in patients who required inhaled corticosteroids for maintenance treatment of asthma (ICS patients). Methods: Five hundred seventy patients were randomly assigned to receive one of the following inhaled treatments through the Diskus device (Glaxo Wellcome, Research Triangle Park, NC) for 12 weeks: fluticasone propionate 100 μg twice daily (FP100BID) or 200 μg once daily (FP200QD) or placebo. Results: BD patients treated with FP100BID, FP200QD, and placebo had mean increases in FEV₁ from baseline to end point of 0.49 L, 0.37 L, and 0.21 L, respectively (P < .001, FP100BID vs placebo; P = .05, FP200QD vs placebo). ICS patients treated with FP100BID and FP200QD had mean increases in FEV₁ of 0.27 L and 0.11 L, respectively, compared with a decrease in FEV₁ of –0.08 L with placebo (P < .001, FP100BID vs placebo; P = .023, FP200QD vs placebo). BD patients treated with FP100BID and FP200QD had mean increases in morning peak expiratory flow from baseline to end point of 31 L/min and 27 L/min, respectively, compared with a 1 L/min increase in patients treated with placebo. ICS patients treated with FP100BID had a mean increase in morning peak expiratory flow (from baseline to end point) of 18 L/min compared with mean decreases of –3 L/min and –12 L/min in the FP200QD and placebo groups, respectively. More patients were withdrawn from placebo (26% and 48%, in BD and ICS patients, respectively) than from fluticasone propionate (7%-9% [BID-QD] and 18%-32% [BID-QD], in BD and ICS patients, respectively) because of failure to meet predetermined asthma stability criteria. Conclusion: The efficacies of FP100BID and FP200QD were comparable with regard to improvement in pulmonary function and asthma stability in BD patients. In ICS patients, asthma control was maintained with FP200QD, whereas FP100BID provided greater improvements in pulmonary function and asthma stability.

Once-daily budesonide via Turbuhaler improves symptoms in adults with persistent asthma.

BACKGROUND: Previous studies have demonstrated the efficacy and safety of twice-daily budesonide Turbuhaler (Pulmicort Turbuhaler, AstraZeneca, Wilmington, DE) for the treatment of mild to severe asthma. OBJECTIVE: To compare the efficacy and safety of budesonide Turbuhaler administered once daily each morning with placebo in inhaled corticosteroid-naive adults with persistent asthma. METHODS: In this randomized, double-blind, placebo-controlled, multicenter study, 177 adults (aged 18 to 70 years) received placebo or once-daily budesonide Turbuhaler (400 microg) for 12 weeks. Efficacy variables included mean changes from baseline in forced expiratory volume in 1 second (FEV1) and AM/PM peak expiratory flow rate (PEFR), and nighttime/daytime asthma symptom scores, patient discontinuations, use of breakthrough medication (albuterol), forced vital capacity (FVC), forced expiratory flow between 25% and 75% of FVC (FEF25%-75%), and quality of life assessments. Safety was evaluated based on adverse events, physical examinations, vital signs, and laboratory tests. RESULTS: Demographic and baseline characteristics were comparable between study groups. The mean percentages of predicted FEV1 at baseline were 71.9 +/- 9.8 in patients receiving budesonide Turbuhaler and 70.6 +/- 11.0 in patients receiving placebo. Mean changes from baseline over the 12-week treatment period in FEV1 were significantly (P = 0.007) improved in patients receiving once-daily budesonide Turbuhaler compared with placebo (0.31 L and 0.17 L, respectively). Significant (P < or = 0.037) improvements over placebo also were observed in AM PEFR, nighttime/daytime asthma symptoms, and albuterol use with budesonide Turbuhaler treatment. Adverse events were generally mild or moderate in intensity and similar between study groups. CONCLUSIONS: Budesonide Turbuhaler 400 microg administered once daily in the AM is efficacious and safe for inhaled corticosteroid-naive asthmatic adults.     

Fluticasone propionate/salmeterol combination compared with montelukast for the treatment of persistent asthma.

BACKGROUND: Asthma is a chronic disease characterized by inflammation and bronchoconstriction. Medications that are able to effectively treat both components are advantageous. OBJECTIVE: To compare the efficacy of an inhaled corticosteroid and a long-acting beta2-agonist combination product with a leukotriene antagonist for initial maintenance therapy in patients who were symptomatic while receiving short-acting beta2-agonists alone. METHODS: A 12-week, randomized, double-blind, double-dummy, multicenter study was conducted in 432 patients 15 years of age and older with persistent asthma who were symptomatic on short-acting beta2-agonists alone. Fluticasone propionate 100 microg and salmeterol 50 microg combination product (FSC) twice daily or montelukast 10 mg once daily was administered. RESULTS: At endpoint, compared with montelukast, FSC significantly increased morning predose forced expiratory volume in 1 second (0.61 +/- 0.03 L vs 0.32 +/- 0.03 L), morning peak expiratory flow rate (peak expiratory flow rate; 81.4 +/- 5.9 L/minute vs 41.9 +/- 4.8 L/minute), evening peak expiratory flow rate (64.6 +/- 5.3 L/minute vs 38.8 +/- 4.7 L/minute), the percentage of symptom-free days (40.3 +/- 2.9% vs 27.0 +/- 2.7%), the percentage of rescue-free days (53.4 +/- 2.8% vs 26.7 +/- 2.5%), and the percentage of nights with no awakenings (29.8 +/- 2.5% vs 19.6 +/- 2.1%) (P < or = 0.011, all comparisons). At endpoint, FSC significantly reduced asthma symptom scores (-1.0 +/- 0.1 vs -0.7 +/- 0.1) and rescue albuterol use (-3.6 +/- 0.2 puffs/day vs -2.2 +/- 0.2 puffs/day) compared with montelukast (P < 0.001). At endpoint, patients treated with FSC also had a significantly greater improvement in quality of life scores and were more satisfied with their treatment compared with montelukast-treated patients (P < or = 0.001). Both treatments were well tolerated. CONCLUSIONS: Initial maintenance therapy with FSC provides greater improvement in asthma control and patient satisfaction than montelukast.     

Comparison of once-daily to twice-daily treatment with mometasone furoate dry powder inhaler.

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.     

Fluticasone propionate/salmeterol combination provides more effective asthma control than low-dose inhaled corticosteroid plus montelukast

BACKGROUND: Asthma is a disease of chronic inflammation and bronchoconstriction. Inhaled corticosteroids (ICSs) provide important anti-inflammatory treatment but may not provide optimal control of asthma when taken alone. Two therapeutic alternatives for enhanced asthma control are to substitute the combination of fluticasone propionate (FP) and salmeterol (FP/Salm Combo) through the Diskus inhaler or to add montelukast to existing ICS therapy. OBJECTIVE: We compared the efficacy and safety of FP/Salm Combo through the Diskus inhaler versus montelukast added to FP (FP + montelukast) in patients whose symptoms were suboptimally controlled with ICS therapy. METHODS: We performed a multicenter, double-blind, double-dummy, parallel-group, 12-week study in 447 patients with asthma who were symptomatic at baseline while receiving low-dose FP. Patients were treated for 12 weeks with one of the following: (1) combination of FP 100 microg plus salmeterol 50 microg twice daily through the Diskus inhaler, or (2) FP 100 microg twice daily through the Diskus inhaler plus oral montelukast 10 mg once daily. RESULTS: FP/Salm Combo treatment provided better overall asthma control than FP + montelukast with significantly greater improvements in morning peak expiratory flow (+24.9 L/min vs +13.0 L/min, P <.001), evening peak expiratory flow (+18.9 L/min vs +9.6 L/min, P <.001), and forced expiratory volume in 1 second (+0.34 L vs +0.20 L, P <.001), as well as a change in the percentage of days with no albuterol use (+26.3% vs +19.1%, P =.032) and the shortness of breath symptom score (-0.56 vs -0.40, P =.017). The groups had comparable improvements in chest tightness, wheeze, and overall symptom scores. Asthma exacerbation rates were significantly lower (P =.031) in the FP/Salm Combo group (4 patients, 2%) than in the FP + montelukast group (13 patients, 6%). Adverse event profiles were comparable. CONCLUSION: Symptomatic patients on low-dose ICS therapy had significantly greater improvement in asthma control when switched to the FP/Salm Combo than when montelukast was added to ICS therapy.     

Maintenance of asthma control by once-daily inhaled ciclesonide in adults with persistent asthma

BACKGROUND: Inhaled corticosteroids (ICS) are recommended therapy for persistent asthma, although side effects can limit appropriate use. Ciclesonide, a novel ICS, is activated in the lung, thereby reducing systemic activity and side effects. This 12-week, double-blind, randomized, parallel-group, placebo-controlled study evaluated the efficacy and safety of ciclesonide in adults with persistent asthma. METHODS: After a 2-week baseline period in which current ICS treatment was continued, 329 patients were randomized to receive ciclesonide 160 microg (n = 107) or 640 microg (n = 112) (ex-actuator doses, equivalent to 200 and 800 microg ex-valve, respectively), or placebo (n = 110) once daily in the morning. Efficacy was monitored by asthma symptom scores, rescue medication use, morning and evening peak expiratory flow (PEF) measurements, spirometry, and probability of study completion without experiencing lack of efficacy. RESULTS: Morning PEF remained stable with either ciclesonide dose but decreased with placebo; the differences were significant (P < 0.0001) for both ciclesonide doses vs placebo. The forced expiratory volume in 1 s and forced vital capacity decreased significantly with placebo (P < 0.005), but were unchanged with ciclesonide. Lack of efficacy was significantly greater for patients switched to placebo (63%) than it was for those treated with ciclesonide 160 microg (30%) (P < 0.0001 vs placebo) or ciclesonide 640 microg (31%) (P < 0.0001 vs placebo). There were no significant differences between the two tested doses of ciclesonide with respect to efficacy and safety. Serum and 24-h urine cortisol were unaffected by ciclesonide treatment. Both doses of ciclesonide were well tolerated with no cases of oral candidiasis. CONCLUSION: Ciclesonide (160 or 640 microg) once daily in the morning effectively maintains asthma control, does not affect cortisol levels, and has an adverse event profile comparable with placebo in adults with primarily mild to moderate asthma.     

Efficacy and safety of dry powder fluticasone propionate in children with persistent asthma.

BACKGROUND: Flovent Diskus is a powder formulation of the inhaled corticosteroid fluticasone propionate (FP) delivered via a breath-actuated, multidose inhaler. OBJECTIVE: To determine the efficacy and safety of dry powder FP administered once or twice daily (200 microg per day) to children with persistent asthma. METHODS: Twelve-week, randomized, double-blind, placebo-controlled, multicenter trial with a 52-week, open-label extension. Children aged 4 to 11 were required to have pulmonary function 50% to 85% of predicted values. The population was stratified for baseline therapy (inhaled corticosteroid/cromolyn or bronchodilators only). After a 2-week placebo run-in, 242 patients received dry powder FP 200 microg each morning, dry powder FP 100 microg BID, or placebo for 12 weeks; 192 were rerandomized to the QD or BID regimen for an additional 52 weeks of open-label treatment. Primary endpoints were mean changes in FEV1 and morning PEF recorded at clinic visits. RESULTS: Both dry powder FP regimens significantly improved FEV1, evening PEF, and asthma symptoms at the double-blind phase endpoint (P < or = .017 compared with placebo). The BID regimen also significantly improved morning PEF and nighttime awakenings due to asthma (P < or = .005). Among patients previously treated with inhaled corticosteroids/cromolyn, improvements observed with the QD and BID regimens were similar. Patients switched from BID to open-label QD treatment showed additional improvements at week 52 generally comparable to patients who received the BID regimen during both phases. Fluticasone propionate was well tolerated for up to 64 weeks with few reports of drug-related adverse events or morning plasma cortisol abnormalities. CONCLUSIONS: Once daily dosing of dry powder FP 200 microg is an effective and convenient alternative for children whose asthma is controlled with a more frequent dosing regimen of inhaled corticosteroids.     

The addition of salmeterol to fluticasone propionate versus increasing the dose of fluticasone propionate in patients with persistent asthma. Salmeterol Study Group.

BACKGROUND: Current treatment guidelines define inhaled corticosteroids such as fluticasone propionate (FP) as the cornerstone of anti-inflammatory therapy for asthma. OBJECTIVE: The objective was to evaluate the efficacy and safety of adding salmeterol therapy to patients who remain symptomatic while receiving FP as compared with increasing the dose of FP. METHODS: In a multicenter, double-blind study conducted over 24-weeks, 437 patients aged 12 years and older and receiving FP 88 microg twice daily for 2 to 4 weeks were randomly assigned to receive either salmeterol (42 microg twice daily) or FP 220 microg twice daily. The primary efficacy endpoint was morning peak expiratory flow. Secondary measures included FEV1, symptom scores, nighttime awakenings, and supplemental albuterol use. Safety was assessed by reported adverse events and asthma exacerbations. RESULTS: The addition of salmeterol resulted in significantly greater improvements in lung function and symptom control as compared with increasing the dose of FP. Over weeks 1 to 24, morning peak expiratory flow was increased by 47 L/min from baseline with salmeterol treatment as compared with 24 L/min with FP 220 microg twice daily (P < .001) while the percent of symptom-free days increased from baseline by 26% of days as compared with 10% of days (P < .001). The adverse event profiles were similar between groups and fewer exacerbations were reported with salmeterol treatment. CONCLUSIONS: The addition of salmeterol therapy to patients who remain symptomatic while using a low dose of FP was clinically and statistically superior to increasing the dose of FP.     

Dose-ranging study of mometasone furoate dry powder inhaler in the treatment of moderate persistent asthma using fluticasone propionate as an active comparator.

BACKGROUND: Mometasone furoate (MF; Schering-Plough, Madison, NJ), is a glucocorticoid with high local potency and low potential systemic availability. OBJECTIVES: To compare the relative efficacy and safety of a new formulation of MF, coupled with a recently designed dry powder inhaler (DPI), in the treatment of patients with moderate persistent asthma. Fluticasone propionate administered by Diskhaler (FP Diskhaler, 250 microg twice a day; Glaxo Wellcome, Research Triangle Park, NC) was used as an active control. DESIGN: A randomized, parallel group, double-blind (for MF-DPI dosage), evaluator-blind (for MF-DPI vs FP) trial. SETTING: Sixty centers in 20 countries. PATIENTS: Seven hundred thirty-three patients with moderate persistent asthma on inhaled corticosteroid treatment. INTERVENTIONS: Discontinuation of previous inhaled corticosteroid and initiation of one of four study treatments: three doses of MF-DPI (100, 200, and 400 microg twice daily) and one of FP (250 microg twice daily >12 weeks). RESULTS: FEV1 (primary efficacy variable) was evaluated as the mean change from baseline to endpoint (last evaluable visit). All dosage groups showed improvement at endpoint. Only 400 microg twice daily of MF-DPI (+0.19 L) was statistically different from 100 microg twice daily of MF-DPI (+0.07 L; P = 0.02). MF-DPI (200 microg twice daily) and FP Diskhaler groups showed similar improvement (+0.16 L). Greater improvement in most secondary variables (forced expiratory flow between 25% and 75% of vital capacity, and morning and evening peak expiratory flows) also resulted from treatment with 200 or 400 microg twice daily of MF-DPI or with FP Diskhaler, compared with 100 microg twice daily of MF-DPI. Overall, a total daily 800-microg dose of MF-DPI conferred no significant additional benefit >400 microg of MF-DPI. The incidence of oral candidiasis was 1%, 7%, 10%, and 10% in the 100, 200, and 400 microg twice daily of MF-DPI and FP groups, respectively. CONCLUSIONS: A total daily dose of 400 microg of MF-DPI provides clinical benefit comparable to that observed with a total daily dose of 500 microg of FP Diskhaler.     

Low-dose fluticasone propionate compared with montelukast for first-line treatment of persistent asthma: a randomized clinical trial

BACKGROUND: Both inhaled corticosteroids and leukotriene modifiers are used in the maintenance treatment of persistent asthma. OBJECTIVE: The goal was to compare the efficacy and safety of low-dose fluticasone propionate (FP) and montelukast as first-line maintenance therapy in symptomatic patients by using short-acting beta2-agonists alone to treat persistent asthma. METHODS: In this multicenter, randomized, double-blind, double-dummy, parallel-group study, 533 patients (>15 years old) with persistent asthma who remained symptomatic while taking short-acting beta2-agonists alone were treated with FP (88 microg [2 puffs of 44 microg] twice daily) or montelukast (10 mg once daily) for 24 weeks. RESULTS: Compared with treatment with montelukast, treatment with FP resulted in significantly greater improvements at endpoint in morning predose FEV(1) (22.9% vs 14.5%, P <.001), forced midexpiratory flow (0.66 vs 0.41 L/sec, P <.001), forced vital capacity (0.42 vs 0.29 L, P =.002), morning peak expiratory flow (PEF) (68.5 vs 34.1 L/min, P <.001), and evening PEF (53.9 vs 28.7 L/min, P <.001). Similar improvements in PEF were observed in patients with milder asthma (>70%-80% predicted FEV(1)). At endpoint, FP was more effective than montelukast at decreasing rescue albuterol use (3.1 puffs/day vs 2.3 puffs/day, P <.001), asthma symptom scores (-0.85 [48.6% decrease] vs -0.60 [30.5%], P <.001), and nighttime awakenings due to asthma (-0.64 awakenings/night [62% decrease] vs -0.48 awakenings/night [47.5%], P =.023), and FP increased the percentage of symptom-free days (32.0% vs 18.4% of days, P <.001) compared with montelukast. The adverse event and asthma exacerbation profiles for FP and montelukast were similar. CONCLUSIONS: Low-dose FP is more effective than montelukast as first-line maintenance therapy for patients with persistent asthma who are undertreated and remain symptomatic while taking short-acting beta2-agonists alone.     

Mometasone furoate administered once daily is as effective as twice-daily administration for treatment of mild-to-moderate persistent asthma

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.     

Once-daily evening administration of mometasone furoate in asthma treatment initiation.

BACKGROUND: In a previous study, a 200-microg once-daily evening dose of mometasone furoate dry powder inhaler (DPI) was effective in patients with asthma previously taking inhaled corticosteroids. No studies have been conducted to test the effect of a once-daily evening dose in patients previously using only short-acting beta2-adrenergic agonists (SABAs) for symptom relief. OBJECTIVE: To evaluate the effectiveness of mometasone furoate DPI administered once daily in the evening as initial controller therapy in patients previously using SABAs alone for asthma. METHODS: Patients with mild-to-moderate persistent asthma from 18 US centers participated in a 12-week, randomized, double-blind, placebo-controlled study. Patients received either mometasone furoate DPI, 200 microg, or placebo once daily in the evening. The primary efficacy variable was the change in forced expiratory volume in 1 second from baseline to the end point (last evaluable visit). Other measurements included forced vital capacity, forced expiratory flow between 25% and 75%, morning and evening peak expiratory flow, asthma symptoms, use of albuterol, nocturnal awakenings, physicians' evaluation of response to therapy, and time to asthma worsening. RESULTS: At the end point, the mean increase in forced expiratory volume in 1 second relative to baseline for the mometasone furoate DPI group of 0.43 L (16.8%) was significantly greater than that for the placebo group of 0.16 L (6.0%) (P < .01). Morning peak expiratory flow, forced vital capacity, and forced expiratory flow between 25% and 75% also significantly improved with mometasone furoate DPI treatment relative to placebo (P < .01). Once-daily dosing with mometasone furoate DPI was well tolerated. CONCLUSION: Mometasone furoate DPI (200 microg) administered once daily in the evening significantly improves pulmonary function in patients previously using SABAs alone for asthma control.     

Leukotriene receptor antagonist, montelukast, can reduce the need for inhaled steroid while maintaining the clinical stability of asthmatic patients

BACKGROUND: Oral leukotriene receptor antagonists have been shown to have efficacy in chronic asthma. OBJECTIVE: To determine whether the addition of montelukast could lead to a reduction in inhaled corticosteroid dose without a significant decrease in peak expiratory flow rate (PEFR). METHODS: After a 4-week run-in period, 191 moderate-to-severe asthmatic patients whose asthma had been well controlled with daily inhaled corticosteroid therapy (beclometasone dipropionate 800 to 1600 micro g/day), were randomly assigned to one of two treatments - placebo (n = 98) or montelukast 10 mg once daily (n = 93) - for a 24-week, multicentre, double-blind, treatment period. At the beginning of the active treatment period, the daily dose of inhaled corticosteroid was halved in all of the patients. In addition, the inhaled corticosteroid dose was subsequently titrated every 8 weeks, based on PEFR, asthma symptoms and beta-agonist use. RESULTS: After 8 weeks of a 50% reduction in inhaled corticosteroid use, morning PEFR increased by 5.3 +/- 32.3 L/min from baseline in patients receiving montelukast and significantly decreased by 6.9 +/- 29.0 L/min in those receiving placebo (P = 0.035). In addition, evening PEFR significantly decreased by 9.8 +/- 28.5 L/min (P = 0.003) in the placebo group, but was maintained in the montelukast group. In spite of a subsequent 50% reduction in the inhaled corticosteroid dose every 8 weeks, morning and evening PEFRs were maintained over the 24-week treatment period in the montelukast group; PEFR significantly decreased in the placebo group. There was a significant difference between the two groups with regard to morning PEFR, therapy score and asthmatic score at weeks 8, 16 and 24, as well as evening PEFR at week 8. However, the symptom scores were not significantly different between the two groups or within each group. CONCLUSION: These data suggest that montelukast reduces the need for inhaled corticosteroids while maintaining asthma control over a 24-week period. Therefore, montelukast may be useful for long-term treatment in patients with asthma who require high doses of inhaled corticosteroids.     

Efficacy and safety of fluticasone propionate 44 microg/salmeterol 21 microg administered in a hydrofluoroalkane metered-dose inhaler as an initial asthma maintenance treatment.

BACKGROUND: We wanted to evaluate whether treatment with an inhaled corticosteroid and an inhaled long-acting beta2-agonist is more effective than an inhaled corticosteroid alone for patients using as-needed albuterol who are initiating maintenance treatment. OBJECTIVE: To compare the efficacy and safety of twice-daily fluticasone propionate (FP) 88 microg and salmeterol 42 microg combined in a chlorofluorocarbon (CFC)-free (hydrofluoroalkane 134a) metered-dose inhaler (MDI) with the individual agents alone, each delivered through an MDI containing CFC propellants, in patient with persistent asthma previously uncontrolled with as-needed short-acting beta2-agonists alone. METHODS: Patients with asthma (n = 283) were randomized to twice-daily treatment for 12 weeks with FP 88 microg combined with salmeterol 42 microg (FSC) in a CFC-free MDI or the individual components alone from CFC-containing MDIs. RESULTS: At endpoint, mean change from baseline in morning predose forced expiratory volume in 1 second was significantly (P < or = 0.016) greater with FSC (0.69 L) compared with FP (0.51 L) or salmeterol (0.47 L). Fewer patients treated with FSC withdrew due to worsening asthma (1%) compared with FP (3%) or salmeterol (8%; P = 0.024). FSC significantly increased (P < or = 0.002) morning and evening peak expiratory flow rate at endpoint (66.5 and 51.5 L/min, respectively) compared with FP (43.0 and 29.9 L/min, respectively) and salmeterol (29.2 and 21.6 L/min, respectively). In addition, asthma symptom scores were reduced, and percentages of days with no asthma symptoms increased in all treatment groups. CONCLUSIONS: Treatment with FSC in a CFC-free MDI is more effective than FP or salmeterol alone in asthma patients who are symptomatic taking short-acting beta2-agonists alone.     

Once-daily ciclesonide improves lung function and is well tolerated by patients with mild-to-moderate persistent asthma

BACKGROUND: Inhaled corticosteroids are recommended as first-line therapy for persistent asthma. OBJECTIVE: We sought to assess the efficacy and safety of ciclesonide once daily in patients with mild-to-moderate persistent asthma. METHODS: An integrated analysis of 2 identical, multicenter, double-blind, randomized, parallel-group, placebo-controlled trials was conducted. Patients (n = 1015; aged > or =12 years) with mild-to-moderate asthma (FEV1 of 60% to 85% of predicted value) were randomized to ciclesonide 80 microg (CIC80), 160 microg (CIC160), or 320 microg (CIC320), once daily (exactuator doses) in the morning or placebo for 12 weeks. RESULTS: All ciclesonide groups showed significant improvements from baseline to week 12 in FEV1 compared with the placebo group (CIC80, 0.12 L [P = .0007]; CIC160, 0.13 L [P = .0004]; and CIC320, 0.14 L [P < .0001]). Likewise, FEV1 percent predicted, morning and evening peak expiratory flow, 24-hour asthma symptom score, daily albuterol use, and nighttime awakenings were significantly improved in all ciclesonide groups compared with the placebo group. Overall ciclesonide safety profile and rates of oropharyngeal adverse events for all groups were low and similar to those of the placebo group. Fewer ciclesonide-treated patients exhibited asthma-aggravated adverse events, and fewer ciclesonide-treated patients discontinued the study for any reason or because of a lack of efficacy compared with those in the placebo group. No suppression of hypothalamic-pituitary-adrenal-axis function (as assessed by means of 24-hour urinary cortisol levels corrected for creatinine and peak serum cortisol levels after stimulation with low-dose [1 microg] cosyntropin) was observed with any dose of ciclesonide. CONCLUSIONS: In this integrated analysis, ciclesonide once daily administered in the morning is effective and well tolerated.     

Once-daily mometasone furoate dry powder inhaler in the treatment of patients with persistent asthma.

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.     

Administration of budesonide once daily by means of turbuhaler to subjects with stable asthma.

BACKGROUND: Optimal management of chronic, mild-to-moderate asthma with inhaled steroids may include use of the lowest possible doses, as recommended in guidelines, and a reduction in the frequency of daily administration for greater convenience. Lower doses and once daily treatment with inhaled steroids must be rigorously evaluated in controlled clinical trials. OBJECTIVES: The objective of this study was to assess the efficacy and safety of once daily treatment with budesonide in subjects with stable asthma. METHODS: Once daily budesonide was assessed in 309 adult subjects, including those who were and were not using an inhaled steroid at baseline. The subjects were stratified by inhaled steroid use and randomly assigned to one of 3 treatments: 200 microgram budesonide, 400 microgram budesonide, or placebo administered by means of Turbuhaler once daily in the morning for 6 weeks. Beyond this point, treatment was continued unchanged for another 12 weeks (maintenance) in those receiving 200 microgram budesonide once daily and placebo. In those who received 400 microgram budesonide once daily, the dose was reduced to 200 microgram once daily at week 6 and held constant for the remaining 12 weeks (400/200 microgram group). Primary efficacy endpoints were mean change from baseline in FEV1 and morning peak expiratory flow. RESULTS: Once daily budesonide was well tolerated and resulted in significant improvements in all efficacy endpoints, even though baselines were well stabilized. Baseline lung function was elevated with little room for improvement; however, mean increases in FEV1 during the maintenance period were 0.10 L and 0.11 L in the 200 microgram and 400/200 microgram groups, respectively, versus a decrease of -0.09 L in the placebo arm (P <.001). Results for peak expiratory flow were similar. Significant improvements in secondary endpoints, including symptoms, beta-agonist use, and quality of life, also developed with budesonide 200 and 400 microgram once daily. CONCLUSION: Inhaled budesonide, in doses as low as 200 microgram, may be an appropriate introductory or maintenance dose in subjects with stable, mild-to-moderate asthma.     

Loss of response to treatment with leukotriene receptor antagonists but not inhaled corticosteroids in patients over 50 years of age.

BACKGROUND: There are limited published data describing the relative efficacy of available treatment options in younger versus older patients with persistent asthma. OBJECTIVE: To compare the efficacy of fluticasone propionate (FP) and zafirlukast (Z) in younger (12 to 49 years of age) versus older (50 years and older) patients with asthma. METHODS: A retrospective analysis of five randomized, double-blind, double-dummy studies 4 to 12 weeks in duration of 1,742 patients <50 years of age and 243 patients aged 50 years or older. Interventions were inhaled fluticasone propionate (FP) 88 microg, oral Z 20 mg, or placebo twice daily. RESULTS: Treatment with FP resulted in significantly greater improvements than Z in all efficacy measurements (except for nighttime awakenings) regardless of age. In older patients, treatment with FP significantly increased pulmonary function compared with Z: FEV (FP= +0.19 L; placebo = -0.34 L; Z = -0.06 L); AM peak expiratory flow rate [PEFR] (FP = +25 L/minute; placebo = -18 L/minute; Z = +4 L/minute); PM PEFR (FP = +24 L/minute; placebo = -24 L/minute; Z = +5 L/minute; P < or = 0.023; for all comparisons). Compared with Z, treatment with FP in older patients also resulted in significantly greater increases in the percentage of symptom-free days (25% vs 13%) and rescue-free days (35% vs 17%); and significantly greater reductions in albuterol use (-1.6 vs -0.3 puffs/day) and the percentage of patients with exacerbations (2.7% vs 14.3%; P < or = 0.031). CONCLUSIONS: Regardless of age, treatment with FP in patients with asthma significantly improved pulmonary function and overall asthma control. In contrast, treatment with Z in older patients with asthma resulted in small improvements in asthma symptoms, whereas lung function improved minimally or not at all, and exacerbations increased. These data suggest that FP effectively controls inflammation in older patients, whereas Z may mask inflammation and may not provide the level of bronchodilatory or anti-inflammatory activity needed for effective asthma control in older patients.
