Abstract
Rationale Asthma is a rhythmic inflammatory disease of the airway, regulated by the circadian clock. "Spill-over" of airway inflammation into the systemic circulation occurs in asthma and is reflected in circulating immune cell repertoire. The objective of the present study was to determine how asthma impacts peripheral blood diurnal rhythmicity. Methods 10 healthy and 10 mild/moderate asthma participants were recruited to an overnight study. Blood was drawn every 6 h for 24 h. Main results The molecular clock in blood cells in asthma is altered; PER3 is significantly more rhythmic in asthma compared to healthy controls. Blood immune cell numbers oscillate throughout the day, in health and asthma. Peripheral blood mononucleocytes from asthma patients show significantly enhanced responses to immune stimulation and steroid suppression at 16:00 h, compared to at 04:00 h. Serum ceramides show complex changes in asthma: some losing and others gaining rhythmicity. Conclusions This is the first report showing that asthma is associated with a gain in peripheral blood molecular clock rhythmicity. Whether the blood clock is responding to rhythmic signals received from the lung or driving rhythmic pathology within the lung itself is not clear. Dynamic changes occur in serum ceramides in asthma, probably reflecting systemic inflammatory action. The enhanced responses of asthma blood immune cells to glucocorticoid at 16:00 h may explain why steroid administration is more effective at this time.

Abstract
The circadian clock is a collection of endogenous oscillators with a periodicity of ~ 24 h. Recently, our understanding of circadian rhythms and their regulation at genomic and physiologic scales has grown significantly. Knowledge of the circadian influence on biological processes has provided new possibilities for novel pharmacological strategies. Directly targeting the biological clock or its downstream targets, and/or using timing as a variable in drug therapy are now important pharmacological considerations. The circadian machinery mediates many aspects of the inflammatory response and, reciprocally, an inflammatory environment can disrupt circadian rhythms. Therefore, intense interest exists in leveraging circadian biology as a means to treat chronic inflammatory diseases such as sepsis, asthma, rheumatoid arthritis, osteoarthritis, and cardiovascular disease, which all display some type of circadian signature. The purpose of this review is to evaluate the crosstalk between circadian rhythms, inflammatory diseases, and their pharmacological treatment. Evidence suggests that carefully rationalized application of chronotherapy strategies - alone or in combination with small molecule modulators of circadian clock components - can improve efficacy and reduce toxicity, thus warranting further investigation and use.

Abstract
Asthma exhibits a marked time of day variation in symptoms, airway physiology, and airway inflammation. This is also seen in chronic obstructive pulmonary disease (COPD), but to a lesser extent. Our understanding of how physiological daily rhythms are regulated by the circadian clock is increasing, and there is growing evidence that the molecular clock is important in the pathogenesis of these two airway diseases. If time of day is important, then it follows that treatment of asthma and COPD should also be tailored to the most efficacious time of the day, a concept known as 'chronotherapy'. There have been a number of studies to determine the optimal time of day at which to take medications for asthma and COPD. Some of these agents are already used 'chronotherapeutically' in practice (often at night-time). However, several studies investigating systemic and inhaled corticosteroids have consistently shown that the best time of day to take these medications for treating asthma is in the afternoon or early evening and not in the morning, when these medications are often prescribed. Future, large, randomized, placebo-controlled studies of systemic and inhaled corticosteroids in asthma and COPD are needed to inform clinical practice.

Abstract
BACKGROUND Once-daily inhaled corticosteroids (ICSs) are widely used as first-line therapy in patients with asthma. OBJECTIVE To compare the efficacy of ICSs administered once daily in the morning or evening as determined by lung function. METHODS Medline, Embase, and the Cochrane Central Register were searched for relevant clinical trials. The primary outcome was lung function assessed as trough forced expiratory volume in 1 second and peak expiratory flow at end point. RESULTS Eight randomized clinical trials involving 1,234 patients were analyzed. The total number of patients treated with once-daily ICS in the morning and evening was 628 and 606, respectively. Pooled estimates showed that ICS administered once daily in the evening resulted in mild improvements in trough forced expiratory volume in 1 second (mean difference 0.05 L; 95% confidence interval 0.01-0.09; P = .026; I2 = 22.5%) and morning peak expiratory flow (mean difference 13.92 L/min; 95% confidence interval 5.77-22.06; P = .001; I2 = 13%) at end point compared with morning dosing. The change in use of rescue medicine and the incidence of adverse events with once-daily ICS were not significantly different between the 2 dosing times. CONCLUSION Compared with morning dosing, ICSs administered once daily in the evening seemed to provide some benefits in lung function for patients with asthma. However, because of methodologic limitations, further large-scale randomized clinical trials for dosing time of once-daily ICSs are needed.

Abstract
INTRODUCTION Fluticasone furoate (FF) is a novel inhaled corticosteroid (ICS). Vilanterol trifenate (VI) is a new inhaled, selective, long - acting β2 adrenergic agonist (LABA). It is now also marketed as a novel once daily combined ICS/LABA indicated for treatment of moderate and severe asthma. AREAS COVERED FF has a highly specific, fast association and slow dissociation from the glucocorticoid receptor, with a 24 hr duration of action. This, combined with a slow transport out of respiratory cells, creates a long tissue retention period. Vilanterol trifenate (VI) is a new inhaled, selective, long - acting β2 adrenergic agonist, also with a rapid onset of action with a maximal effect within 6 mins and prolonged lung retention with effects on lung function over 24 hours. Expert commentary: Multiple Phase I-III efficacy studies performed on FF and VI have shown an improvement in spirometry as well as symptom control in asthma. The development of once daily ICS/LABA combinations may potentially improve adherence to asthma therapy, but this has yet to be demonstrated.

Abstract
The Optimal Dosing Times of Corticoids. The therapeutic use of Cortisol and its derivatives, anti-inflammatory corticoids, sets delicate problems to resolve because of Cortisol's physiological roles and its circadian rhythms. Cortisol and the majority of its derivatives have desirable and undesirable effects that are time-related administration. The chronothera- peutic optimisation to increase desirable effects and safety of corticoids is shown in the treatment of adrenocortical failure, congenital adrenal hyperplasia and asthma. The knowledge of physiological and physiopathological rhythms of asthma permitted to realize oral treatment optimisation by using a number of corticoids. This knowledge puts in a prominent position the advantages of ciclesonide: a new inhaled corticoid. A chronobiologic approach could be used in a classic optimisation which involves a molecule modification and inhalation like routes of administration.

Abstract
Inhaled corticosteroids are used as one of the first-line drug therapy in patients with asthma. However, their long-term use is associated with various oropharyngeal and systemic side and adverse effects. Design of pro-soft drug is one of the strategies, which was adopted in the design of ciclesonide for mitigation of side effects usually observed with the use of inhaled corticosteroids. Ciclesonide, a pro-soft drug, is converted to an active metabolite desisobutyryl-ciclesonide in the lungs. The anti-inflammatory effect of desisobutyryl-ciclesonide is much higher than ciclesonide, and therefore, the local effect of the metabolite is higher with lower systemic side effects. Ciclesonide has favorable pharmacokinetic and pharmacodynamic properties as inhaled corticosteroid including low oral bioavailability, high plasma protein binding and rapid systemic clearance, high pulmonary deposition and distribution and long pulmonary residence duration. These advantageous properties make ciclesonide a very effective treatment option with low side effects. Various clinical studies support safety and efficacy of ciclesonide use in mild, moderate, and severe asthma patients.

IRANIAN RED CRESCENT MEDICAL JOURNAL 2015; 17:e12859. [PMID: 25763272 PMCID: PMC4341496 DOI: 10.5812/ircmj.12859] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 06/11/2013] [Revised: 01/28/2014] [Accepted: 11/01/2014] [Indexed: 11/16/2022]
Abstract
BACKGROUND Diagnosis and treatment of respiratory tract infections (RTI) in a mass-gathering situation such as hajj is a medical challenge that requires quick decision-making and considerable knowledge about its etiology and treatment methods. High prevalence of RTI during Hajj and tendency of caravan physicians to treat of patients quickly in such situation lead to prescription of parenteral steroids. Nonetheless, no study has focused on the short-term and long-term effects of systemic steroids in Hajj pilgrims with RTI. OBJECTIVES This study focuses on efficacy of systemic consumption of corticosteroids in alleviating symptoms of RTI. PATIENTS AND METHODS This clinical trial was included 1671 pilgrims in Hajj 2012 who had symptoms of RTI based on caravan physician's findings. The patients were divided to two groups to receive either parenteral corticosteroid or other drugs. Patients who received antibiotics for bacterial infections were excluded. This survey concentrated on general symptoms of RTI during Hajj such as fever, musculoskeletal pain, coryza, sore throat, cough, dyspnea, and hoarseness before, 24 hours after, and five days after drug consumption. For classification and analysis of data, SPSS 17 was used. Descriptive statistical and Chi square test were used to compare variables. RESULTS In comparison to corticosteroid injection, treatment without systemic corticosteroids could reduce the fever more significantly within five days (P < 0.05), while it had no effect after 48 hours (P > 0.05). Although corticosteroids alleviated the symptoms during the first 48 hours (P > 0.05), they had no more effect after five days of consumption (P > 0.05). Treatment with medications other than corticosteroid had less effect on reducing coryza (P > 0.05) while corticosteroids had significant alleviating effect on coryza, cough, and musculoskeletal pain (P < 0.05). CONCLUSIONS There is a need to conduct more comprehensive studies on effect of combination therapy with corticosteroids and antibiotics as well as their short-term and long-term adverse effects on the immune system. While injecting corticosteroids is commonly administered in patients with RTI, they are not recommended due to the lack of data on their long-term therapeutic and adverse effects.

Abstract
Purpose To evaluate the efficacy and safety of once-daily ciclesonide in comparison to both levocetirizine alone, and a ciclesonide/levocetirizine combination in patients with seasonal allergic rhinitis (SAR) and perennial allergic rhinitis (PAR). Methods Subjects exhibiting moderate to severe allergic rhinitis for longer than 1 year were randomized in an open-label, 3-arm, parallel group, multicenter study. Subjects received 200 µg ciclesonide, 5 mg levocetirizine, or a combination of both. Changes from baseline until the end-of-study visit (2 weeks following) were evaluated by reflective total nasal symptom scores (rTNSSs), reflective total ocular symptom scores (rTOSSs), physician-assessed overall nasal signs and symptoms severity (PANS), and rhinoconjunctivitis quality-of-life questionnaires (RQLQ). Results Significant improvements in rTNSS, PANS, and RQLQ in the ciclesonide monotherapy group were observed in comparison to the levocetirizine alone group. Three individual symptoms of rTNSS, including runny nose, nasal itching, and congestion, were improved in the ciclesonide-treated group. rTOSS scores for ciclesonide monotherapy improved from baseline, but no superiority over levocetirizine was shown. The absolute score and changes in rTNSS and PANS were positively correlated. Ciclesonide spray was more effective than levocetirizine in reducing nasal symptoms in both SAR and PAR patients. Ciclesonide and levocetrizine were well tolerated alone and in combination. Conclusions Our results provide support for an AR and its Impact on Asthma (ARIA) recommendation stipulating that ciclesonide is superior to levocetirizine for the treatment of AR, with tolerable safety. Addition of levocetirizine to ciclesonide did not give further clinical benefit over monotherapy.

Abstract
BACKGROUND Inhaled corticosteroids (ICSs) are widely used in asthma control. Ciclesonide (CIC) is an ICS with on-site lung activation for potent anti-inflammatory activity. AIMS This study aimed to compare the clinical benefit of CIC with budesonide (BUD) in step-down therapy. METHODS A total of 150 patients with mild-to-moderate asthma well controlled by a combination of ICS and long-acting β2-agonist were randomised to receive either CIC 320 μg (n=75) once daily or 2 inhalations of BUD 200 μg (n=75) twice daily for 12 weeks. The forced expiratory volume in 1s (FEV1), maximum mid-expiratory flow (MMEF) and asthma control test (ACT) scores were measured. Ranked stratification of patients and physicians was assessed. RESULTS Drug adherence was significantly higher in the CIC group than in the BUD group (76.0% vs. 58.7%, P=0.03). The FEV1 and MMEF remained stable throughout the 12-week CIC treatment. In the BUD group, FEV1 significantly decreased at weeks 4 and 12. MMEF had a higher value in the CIC group than in the BUD group. Both patients and physicians ranked CIC over BUD. CONCLUSIONS CIC is more effective and has better drug adherence than BUD as step-down treatment when asthma is well controlled by combination therapy.

Abstract
Asthma severity is classified according to the level of treatment required to control symptoms. Inhaled corticosteroids are the recommended first-line therapy for the treatment of persistent asthma, and when asthma remains uncontrolled, one option is to increase the inhaled corticosteroids dose. However, there is a concomitant risk of increasing local and systemic adverse events, which may impact patient adherence and physician prescribing practices. Ciclesonide is delivered as a prodrug, has high peripheral lung deposition and high protein-binding capabilities, and is rapidly eliminated from the systemic circulation. This article reviews the use of high-dose ciclesonide in patients with severe asthma and considers whether the pharmacology of ciclesonide translates into it being an efficacious and well-tolerated option for patients requiring a step-up in their asthma treatment.

[PMID: 24200619 DOI: 10.1016/j.rmed.2013.07.002] [Citation(s) in RCA: 20] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/22/2013] [Revised: 06/17/2013] [Accepted: 07/01/2013] [Indexed: 10/26/2022]
Abstract
AIM To investigate the effect of time of day of dosing (morning or evening) on lung function following administration of fluticasone furoate (FF)/vilanterol (VI) 100/25 mcg. METHODS Double-blind, placebo-controlled, randomised, three-way crossover study. Subjects with persistent asthma (N = 26) received FF/VI (morning or evening) or matching placebo once-daily for 14 (± 2 days) via dry powder inhaler (DPI). Weighted mean (0-24h) and pre-treatment FEV1 (morning and evening) were determined after the Day 14 evening dose, together with mean pre-treatment (morning and evening) peak expiratory flow (PEF) on Days 2-12. RESULTS FF/VI 100/25 administered morning or evening produced clinically significant increases in weighted mean FEV1: the differences [95% confidence interval (CI)] from placebo were 377 mL [293, 462] and 422 mL [337, 507], respectively; the difference between morning and evening dosing was -44 mL [-125, 36]. Day 14 pre-treatment morning FEV1 differences [95% CI] from placebo were 403 mL [272, 533] and 496 mL [369, 624] after morning and evening dosing, respectively; the morning:evening treatment difference was -94 mL [-221, 34]. Pre-treatment evening FEV1 differences [95% CI] from placebo were 275 mL [169, 380] and 309 mL [205, 413] after morning and evening dosing, respectively; the morning:evening treatment difference was -34 mL [-138, 70]. FF/VI (morning or evening) produced rapid increases in PEF with the full effect apparent after the first dose and maintained throughout the 14-day treatment period. CONCLUSION FF/VI 100/25 produces comparable improvements in lung function whether dosed in the morning or evening in subjects with persistent asthma.

Abstract
Ciclesonide, a novel glucocorticosteroid, through a rapid metabolism to desisobutyryl-ciclesonide (des-ciclesonide), provides an effective treatment option for asthma episodes by the inhaled route of administration. The availability of pharmacokinetic parameters (clearance [CL/F]; volume of distribution [Vd/F]; elimination half-life [T(½)]; and elimination rate constant [Kel]) in mice, rats, rabbits, and dogs enabled the prediction of human parameter values for des-ciclesonide using the well-accepted tool of allometry after intravenous administration of ciclesonide. However, as a result of the rapid conversion of ciclesonide, it was possible to perform allometry for the CL parameter only. Simple allometry (CL = 4.781W⁰·⁷⁸⁷⁴; R² = 0.9968) appeared to predict the CL of ciclesonide in close proximity of the observed value (observed: 101.25 L/h versus predicted: 135.62 L/h). In a similar manner, simple allometry predicted the human pharmacokinetic parameters of des-ciclesonide (CL/F, Vd/F, T(½), and Kel) within a two- to threefold range of the observed values. The allometric equations for des-ciclesonide parameter values were: CL/F = 4.8166W⁰·⁴⁹² (R² = 0.8598); Vd/F = 19.052W⁰·⁶³² (R² = 0.9049); T(½) = 3.7598W⁻⁰·¹⁶¹¹(R² = 0.8551); and Kel = 0.1832W⁰·¹⁵⁹⁶ (R² = 0.8632). In conclusion, the data suggested that allometry tool may be amenable for the prediction of the pharmacokinetic parameters of des-ciclesonide despite differences in the conversion rates and bioavailability of the active metabolite in various animal species.

Abstract
Ciclesonide is a novel inhaled corticosteroid that is converted in the lungs to its active metabolite, desisobutyryl-ciclesonide (des-CIC). The aim of this study was to compare the deposition of ciclesonide, as well as its conversion to des-CIC, in the oropharyngeal cavity with fluticasone propionate (FP) following inhalation via hydrofluoroalkane-propelled metered-dose inhalers (HFA-MDIs). Eighteen asthmatics inhaled ciclesonide 800 microg followed by FP 1000 microg or vice versa in an open, randomized, 2-treatment, 2-sequence study design. The oropharynx was washed out immediately and at 15, 30, 45, and 60 minutes after inhalation. Samples were analyzed for ciclesonide, des-CIC, and FP using liquid chromatography with tandem mass-spectrometric detection. Concentration-time curves and area under the concentration-time curve (AUC) were calculated for each drug. Ciclesonide and FP were recovered in almost all samples. Within 60 minutes after inhalation, the amounts of both ciclesonide and FP decreased sharply, and low residual levels were detected after 30 minutes. des-CIC was detected in relatively low concentrations, with maximum concentration 30 minutes following inhalation. The AUC(0-60 min) for ciclesonide (250.4 nmol x h/L) and des-CIC (37.8 nmol x h/L) were found to be significantly lower compared with FP (636.2 nmol.h/L, P < .001). Approximately 50% less ciclesonide and 90% less metabolite were present in the oropharynx compared with FP. Less than 20% of the residual ciclesonide in the oropharynx was metabolized to des-CIC. These findings indicate that oropharyngeal deposition of ciclesonide is only half that of FP following inhalation from an HFA-MDI. Furthermore, there is little activation of ciclesonide to its active metabolite in the oropharynx, suggesting a decreased likelihood of inhaled ciclesonide-associated oropharyngeal side effects.

Once-daily fluticasone furoate is efficacious in patients with symptomatic asthma on low-dose inhaled corticosteroids. Ann Allergy Asthma Immunol 2012; 109:353-358.e4. [PMID: 23062392 DOI: 10.1016/j.anai.2012.08.017] [Citation(s) in RCA: 40] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2012] [Revised: 08/09/2012] [Accepted: 08/10/2012] [Indexed: 10/27/2022]
Abstract
BACKGROUND Fluticasone furoate (FF) is an inhaled corticosteroid (ICS) with 24-hour activity in development as a once-daily treatment for the long-term management of asthma. OBJECTIVE To assess the efficacy and safety of 4 doses of once-daily FF administered using a dry powder inhaler in patients (≥12 years) with moderate asthma, uncontrolled on low-dose ICS (fluticasone propionate [FP] 200 μg/day or equivalent). METHODS This double-blind, placebo-controlled, dose-ranging study randomized 622 patients to 1 of 6 treatments: FF (100, 200, 300, or 400 μg) once daily in the evening, FP 250 μg twice daily (active control), or placebo for 8 weeks. The primary endpoint was the change from baseline in predose evening forced expiratory colume in 1 second (FEV1) at week 8. RESULTS At week 8, relative to placebo, all doses of FF once daily and FP twice daily demonstrated significantly (P < .001) greater increases from baseline and greater than 200-mL increases in predose FEV1. There was no evidence of a dose-response relationship between FF doses. Improvement with once-daily FF was similar to or greater than that for twice-daily FP. Secondary efficacy endpoint findings generally supported the efficacy of FF 100 to 400 μg once daily, although statistically significant improvements versus placebo in symptom-free 24-hour periods were only reported for FF 400 μg. There were few withdrawals due to lack of efficacy. Oral candidiasis was reported in 0 to 4% of patients; 24-hour urinary cortisol excretion ratios were similar across active treatment groups and not significantly different from placebo. CONCLUSION FF 100 to 400 μg once daily in the evening is effective and well tolerated in patients with asthma uncontrolled on low-dose ICS, with 100 μg and 200 μg, considered the most applicable doses in this asthma population.

Abstract
Bronchial asthma is a chronic inflammatory disorder of the airways associated with airflow obstruction that is reversible spontaneously or with treatment. Bronchial asthma is a disease based on established circadian rhythm. The symptoms of asthma worsen during midnight to early morning and therefore it is required to deliver the drug in such fashion that effective treatment can be obtained during the time of asthma attacks. Chronotherapy is an approach that fulfills the criteria of drug delivery at a specific time as per the pathophysiological need of the disease, to improve patient compliance. The current article focuses on the chronotherapy of bronchial asthma, methodologies involved for the existing systems, recent updates and different chronopharmaceutical technologies currently available in the market. Chronotherapy with different categories of bronchial asthma medications also has been reviewed.

Abstract
BACKGROUND Fluticasone furoate (FF) is an inhaled corticosteroid that is structurally and functionally distinct from fluticasone propionate and is under development as a once-daily therapy for asthma. OBJECTIVE The objective of this study was to estimate the treatment differences (with 95% CI) in efficacy and safety profile between FF administered once daily in the morning and evening via Rotadisk Diskhaler (see text) in patients with persistent asthma. No hypothesis testing was performed for this comparison. METHODS This was a randomized, double-blind, double-dummy, placebo-controlled, parallel-group study. Patients (ages 16-55 years; peak expiratory flow [PEF] 50%-90% predicted) were randomized to receive 1 of 3 doses of FF Rotadisk or placebo daily for 4 weeks. The sponsor, GlaxoSmithKline, designed the study and selected the study sites. The primary end point was change from baseline in daily trough (pretreatment, prebronchodilator) PEF during the treatment period with FF Rotadisk 100 μg once daily in the morning compared with 100 μg once daily in the evening. Other end points included change from baseline in forced expiratory volume in 1 second, asthma symptom score, adverse events (AEs), 24-hour urinary cortisol excretion, and FF pharmacokinetics. RESULTS Five hundred and seventy-five patients (mean age 36.6 years, 56.9% female) formed the intent-to-treat population and were randomly allocated to FF Rotadisk 100 μg once daily in the morning (n = 144), FF Rotadisk 100 μg once daily in the evening (n = 146), FF Rotadisk 250 μg once daily in the evening (n = 142), or placebo (n = 143). Of these patients, 526 (91.5%) completed the study. A smaller proportion of patients in the placebo group (86.7%) than in the active treatment groups completed the study. Mean difference in PEF change from baseline with FF Rotadisk 100 μg once daily in the morning relative to evening was +13.4 L/min (95% CI, 2.3-24.4). However, morning trough values might have been affected by higher placebo response after morning dosing (18.8 vs 8.8 L/min). Trough PEF improved relative to placebo (P ≤ 0.005), with little difference between FF Rotadisk 100 μg morning (19 L/min) and evening (16 L/min) dosing, as with other efficacy measures. Frequencies of all-cause AEs were similar with FF Rotadisk (32%-39%, 2 serious AEs) and placebo (37%, 1 serious AE). No serious AEs were deemed by the investigator to be related to study treatment. Twenty-four-hour urinary cortisol increased from baseline in all groups, but the increase was significantly lower with FF Rotadisk 250 μg group than placebo. CONCLUSION FF Rotadisk administered once daily in the morning or evening was well tolerated and associated with improvements in lung function and asthma symptoms compared with placebo. Improvements seen for FF Rotadisk 100 μg appear to be comparable for morning and evening dosing. Clinical.trials.govNCT01499446.

Abstract
BACKGROUND This randomized, double-blind, multicenter study was designed to evaluate the efficacy of inhaled once-daily fluticasone furoate (FF) administered in the evening in patients with persistent asthma not controlled by short-acting beta(2) agonists, and to determine the dose(s) suitable for further development. METHODS Of 1459 patients screened, 598 received one of six treatments: placebo, FF (25 μg, 50 μg, 100 μg or 200 μg) once daily each evening, or fluticasone propionate (FP) 100 μg twice daily for 8 weeks. The primary endpoint was change from baseline in pre-dose evening forced expiratory volume in 1 s (FEV(1)). RESULTS A dose-response effect was observed for once-daily FF 25-200 μg including (p < 0.001) and excluding placebo (p = 0.03). FF 50-200 μg once daily significantly increased FEV(1) from baseline (p < 0.05 vs placebo), by >200 mL for FF 100 μg and 200 μg. Significant improvements were also achieved for peak expiratory flow, and percentage symptom-free and rescue-free 24 h periods. The magnitude of effect was at least as good as twice-daily FP. Overall, once-daily FF was well tolerated with no systemic corticosteroid effects. CONCLUSION FF 50-200 μg/day once daily in the evening demonstrated dose-related efficacy in asthma with 100-200 μg appearing to be the optimal doses for further evaluation.

Abstract
Background Inhaled corticosteroids are the recommended first-line treatment for asthma but adherence to therapy is suboptimal. The objectives of this study were to compare the efficacy and safety of once-daily (OD) evening and twice-daily (BD) regimens of the novel inhaled corticosteroid fluticasone furoate (FF) in asthma patients. Methods Patients with moderate asthma (age ≥ 12 years; pre-bronchodilator forced expiratory volume in 1 second (FEV1) 40-85% predicted; FEV1 reversibility of ≥ 12% and ≥ 200 ml) were randomized to FF or fluticasone propionate (FP) regimens in a double-blind, crossover study. Patients were not permitted to have used any ICS for ≥ 8 weeks prior to enrolment and subsequently received doses of FF or FP 200 μg OD, FF or FP 100 μg BD and matching placebo by inhalation for 28 days each. Primary endpoint was Day 28 evening pre-dose (trough) FEV1; non-inferiority of FF 200 μg OD and FF 100 μg BD was assessed, as was superiority of all active treatment relative to placebo. Adverse events (AEs) and 24-hour urinary cortisol excretion were assessed. Results The intent-to-treat population comprised 147 (FF) and 43 (FP) patients. On Day 28, pre-dose FEV1 showed FF 200 μg OD to be non-inferior (pre-defined limit -110 ml) to FF 100 μg BD (mean treatment difference 11 ml; 95% CI: -35 to +56 ml); all FF and FP regimens were significantly superior to placebo (p ≤ 0.02). AEs were similar to placebo; no serious AEs were reported. Urinary cortisol excretion at Day 28 for FF was lower than placebo (ratios: 200 μg OD, 0.75; 100 μg BD, 0.84; p ≤ 0.02). Conclusions FF 200 μg OD in the evening is an efficacious and well tolerated treatment for asthma patients and is not inferior to the same total BD dose.

Abstract
Background Fluticasone furoate (FF) is a novel long-acting inhaled corticosteroid (ICS). This double-blind, placebo-controlled randomized study evaluated the efficacy and safety of FF 200 mcg or 400 mcg once daily, either in the morning or in the evening, and FF 200 mcg twice daily (morning and evening), for 8 weeks in patients with persistent asthma. Methods Asthma patients maintained on ICS for ≥ 3 months with baseline morning forced expiratory volume in one second (FEV1) 50-80% of predicted normal value and FEV1 reversibility of ≥ 12% and ≥ 200 ml were eligible. The primary endpoint was mean change from baseline FEV1 at week 8 in pre-dose (morning or evening [depending on regimen], pre-rescue bronchodilator) FEV1. Results A total of 545 patients received one of five FF treatment groups and 101 patients received placebo (intent-to-treat population). Each of the five FF treatment groups produced a statistically significant improvement in pre-dose FEV1 compared with placebo (p < 0.05). FF 400 mcg once daily in the evening and FF 200 mcg twice daily produced similar placebo-adjusted improvements in evening pre-dose FEV1 at week 8 (240 ml vs. 235 ml). FF 400 mcg once daily in the morning, although effective, resulted in a smaller improvement in morning pre-dose FEV1 than FF 200 mcg twice daily at week 8 (315 ml vs. 202 ml). The incidence of oral candidiasis was low (0-4%) and UC excretion was comparable with placebo for all FF groups. Conclusions FF at total daily doses of 200 mcg or 400 mcg was significantly more effective than placebo. FF 400 mcg once daily in the evening had similar efficacy to FF 200 mcg twice daily and all FF regimens had a safety tolerability profile generally similar to placebo. This indicates that inhaled FF is an effective and well tolerated once-daily treatment for mild-to-moderate asthma. Trial registration NCT00398645

Abstract
Inhaled corticosteroids (ICSs) are the most effective anti-inflammatory agents available for the treatment of asthma and represent the mainstay of therapy for most patients with the disease. Although these medications are considered safe at low-to-moderate doses, safety concerns with prolonged use of high ICS doses remain; among these concerns is the risk of adrenal suppression (AS). AS is a condition characterized by the inability to produce adequate amounts of the glucocorticoid, cortisol, which is critical during periods of physiological stress. It is a proven, yet under-recognized, complication of most forms of glucocorticoid therapy that can persist for up to 1 year after cessation of corticosteroid treatment. If left unnoticed, AS can lead to significant morbidity and even mortality. More than 60 recent cases of AS have been described in the literature and almost all cases have involved children being treated with ≥500 μg/day of fluticasone. The risk for AS can be minimized through increased awareness and early recognition of at-risk patients, regular patient follow-up to ensure that the lowest effective ICS doses are being utilized to control asthma symptoms, and by choosing an ICS medication with minimal adrenal effects. Screening for AS should be considered in any child with symptoms of AS, children using high ICS doses, or those with a history of prolonged oral corticosteroid use. Cases of AS should be managed in consultation with a pediatric endocrinologist whenever possible. In patients with proven AS, stress steroid dosing during times of illness or surgery is needed to simulate the protective endogenous elevations in cortisol levels that occur with physiological stress. This article provides an overview of current literature on AS as well as practical recommendations for the prevention, screening and management of this serious complication of ICS therapy.

Abstract
BACKGROUND Patients with mild persistent asthma constitute about 70% of the asthma population; thus, it is important to know which first-line treatment is best for the management of mild asthma. We compared benefits of first-line treatment with ciclesonide and a combination of fluticasone and salmeterol in patients with mild asthma. METHODS Patients aged 12 to 75 years with mild persistent asthma were enrolled in a randomized, double-blind, placebo-controlled study. After run-in, patients were randomized to ciclesonide 160 μg once daily (CIC160), fluticasone propionate/salmeterol 100/50 μg bid (FP200/S100), or placebo for 52 weeks. The primary variable was time to first severe asthma exacerbation; the coprimary variable was the percentage of poorly controlled asthma days. Patients recorded asthma symptoms and salbutamol use in electronic diaries and completed a standardized version of the Asthma Quality of Life Questionnaire. RESULTS Compared with placebo, the time to first severe asthma exacerbation was prolonged, and lung function was improved with FP200/S100 treatment (P = .0002) but not with CIC160. Both CIC160 and FP200/S100 provided significantly fewer poorly controlled asthma days than placebo (P ≤ .0016 for both active treatments). Moreover, both active treatments provided significantly more asthma symptom-free days (P ≤ .0001), rescue medication-free days (P = .0005, one-sided), and days with asthma control (P ≤ .0033). Overall Asthma Quality of Life Questionnaire scores were significantly higher in both active treatment groups than placebo (P ≤ .0017). CONCLUSIONS In mild asthma, FP200/S100 prolonged time to first severe asthma exacerbation, and CIC160 and FP200/S100 were clinically equieffective for most measures of asthma control.

[PMID: 21067906 DOI: 10.1016/j.rmed.2010.09.016] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2010] [Revised: 09/16/2010] [Accepted: 09/16/2010] [Indexed: 01/18/2023]
Abstract
BACKGROUND The efficacy and safety profile of ciclesonide (CIC) in the treatment of asthma was evaluated in a large patient population in a real-life setting in Germany. METHODS 24,037 patients with persistent mild/moderate bronchial asthma were enrolled into three observational studies with identical design. Data were pooled and analyzed. Patients received ciclesonide (160 μg/day) and were observed for 3 months. FEV(1), PEF, NO, asthma episodes, use of rescue medication and adverse drug reactions (ADR) were recorded. RESULTS Mean (95% CI) FEV(1) significantly increased from 80.7 [80.5; 80.9]% of predicted at baseline to 90.1 [89.9; 90.2]% after 3 months (n = 20,297), mean PEF significantly increased from 338 [335; 340] l/min to 392 [390; 395] l/min (n = 8100). NO was significantly reduced from 53.6 [51.8; 55.4] ppb to 26.2 [25.2; 27.1] ppb (n = 971). The percentage of patients with daily symptoms declined from 24.3% to 1.9%, night-time symptoms from 13.3% to 1.3%, and β(2)-agonists use from 26.9% to 8.8%. ADRs were reported by 51 patients (0.2%). Most frequent ADRs were: dysphonia (n = 11), cough (n = 10), dyspnoea, throat irritation, and oral candidiasis (n = 5 each). 46 patients terminated the study prematurely, 41 due to ADR and 5 due to unknown/missing reason. One patient died due to cardiac failure (no causal relation). CONCLUSION These observational studies under real-life conditions support findings from controlled clinical studies regarding efficacy and tolerability of ciclesonide in patients with mild to moderate bronchial asthma. No unexpected ADRs were detected.

Abstract
OBJECTIVE To investigate the efficacy and safety of ciclesonide in patients with severe asthma over a 1-year period. RESEARCH DESIGN AND METHODS Patients aged 18 - 75 years with persistent asthma were enrolled in a 12-week, double-blind, randomized study and treated with ciclesonide 320 or 640 μg twice daily (b.i.d.) with the option of continuing in a 40-week extension phase (EP). MAIN OUTCOMES MEASURES Change in morning peak expiratory flow (PEF) from baseline to 12 weeks and safety over 1 year. RESULTS 365 patients were randomized and 275 continued into the EP. During 12 weeks' treatment, morning peak expiratory flow significantly increased by 16 l/min (p < 0.001) and 14 l/min (p = 0.001) in the 320 and 640 μg b.i.d. groups, respectively. Both doses significantly reduced total asthma symptom scores by 0.29 (p < 0.0001). In both groups, the incidence of adverse effects (AEs) was low and mean cortisol levels in serum and urine were not suppressed during the EP. CONCLUSIONS Ciclesonide 320 μg b.i.d. sustained lung function and asthma symptoms in patients with severe asthma over 12 weeks' treatment, and maintained lung function during a 40-week EP; ciclesonide 640 μg b.i.d. did not provide additional benefits. Long-term use of ciclesonide was not associated with increased local AEs or negative effects on cortisol levels.

Abstract
The aim of this review is to report the updates in the medical literature on the outcomes associated with inhaled corticosteroid use. This update finds that inhaled corticosteroids remain a frontline choice as controller therapy in the treatment of asthma. Adherence to medications, especially inhaled corticosteroids used as controller medications, is responsible for a decrease in hospital, emergency room and physician visits. All of these translate to reduced asthma-related healthcare costs and an increase in health-related quality of life. There is a need for further research on the role of inhaled corticosteroids in chronic obstructive pulmonary disease outcomes.

Abstract
IMPORTANCE OF THE FIELD Asthma is a chronic disease characterized by airway inflammation and hyper-responsiveness. Inhaled corticosteroids (ICSs) constitute the guideline-recommended first-line therapy for persistent asthma. However, concerns regarding ICS-related adverse events may contribute to their underutilization by physicians and patients. AREAS COVERED IN THIS REVIEW The currently available published data on the pharmacokinetic and pharmacodynamic properties, safety and efficacy of the ICS, ciclesonide, is described. Peer-reviewed publications (1996 - 2009) on the pharmacodynamic and pharmacokinetic profile, safety and efficacy of ciclesonide were reviewed. WHAT THE READER WILL GAIN Ciclesonide is delivered as an inactive prodrug, which is cleaved to the active molecule by intracellular esterases located in the lungs. This and other pharmacodynamic and pharmacokinetic properties may limit the amount of active molecule outside the lung and may reduce the incidence of side effects. Randomized placebo-controlled studies found that ciclesonide can initiate and maintain disease control in subjects with persistent asthma of all disease severities. Moreover, studies have found that ciclesonide is as effective as other ICSs in establishing and controlling disease symptoms. Controlled clinical trials also showed that ciclesonide is associated with minimal systemic and local treatment-related adverse events. TAKE HOME MESSAGE Published findings indicate that ciclesonide is effective at initiating and maintaining asthma control and is well tolerated, with a positive safety profile.

Abstract
Asthma is a chronic inflammatory disease of the airways, and inhaled corticosteroids (ICSs) are recommended as first-line therapy for persistent asthma of all severities. Ciclesonide is a novel ICS, which is administered as an aerosol solution in a metered-dose inhaler, using hydrofluoroalkane-134a as a propellant. Because of the high respirable particle fraction, high pulmonary deposition is obtained in patients, which constitutes the basis of effective therapeutic action. The parent compound, ciclesonide, is pharmacologically inactive and is activated in the target organ, the lung, to form its only pharmacologically active metabolite, desisobutyryl-ciclesonide (des-CIC). Low oral deposition combined with minimal formation of des-CIC in the oropharynx may minimize the typical oropharyngeal adverse events associated with ICSs. Low oral bioavailability, rapid clearance and high protein binding reduce pharmacologically relevant systemic exposure. The unique pharmacokinetic and pharmacodynamic profile of ciclesonide offers a rationale that supports the favourable risk-benefit profile observed in clinical trials in patients with persistent asthma.

Abstract
Although oral inhalers have been mass produced for more than 50 years, there is a large body of literature in which evidence has been provided that patients either misuse their inhalers inadvertently or deliberately, thereby reducing their intended efficacy or, in the worst cases, rendering them altogether ineffective. In general, inhalers are becoming increasingly complicated with the incorporation of add-on devices, miniaturized electronics and ever more complex mechanical systems that aid aerosol delivery to the lower respiratory tract and, at the same time provide user feedback. However, these benefits often come at a significant cost, and there are signs that increasing attention will need to be given to the cost-benefit equation in the future. This review explores the development of pressurized metered-dose inhalers, dry powder inhalers and devices for liquid-droplet dispersal and inhalation from the perspective of the patient, by focusing on aspects that improve user interaction. These include designed-in features, such as breath-enhanced or breath-actuated operation that interact with the breathing pattern of the user, as well as more direct feedback aids that confirm, to the patient or healthcare provider that the dose has been delivered and that the patient has inhaled.

Abstract
Ciclesonide is a novel inhaled corticosteroid used in the continuous treatment of mild-to-severe asthma. Its formulation and mechanism of action yield a low oral and systemic bioavailability, and high pulmonary deposition. In multiple clinical trials, ciclesonide is at least as effective as either fluticasone propionate or budesonide at symptom control, while in many cases having improved safety outcomes and tolerability. The improved safety and comparable efficacy profiles of ciclesonide demonstrated in current studies could potentially yield a treatment option that may lead to improved adherence and outcome.

Abstract
Ciclesonide (Alvesco) is an inhaled corticosteroid used in the preventative treatment of persistent bronchial asthma in adults, adolescents and, in some countries, children. The drug is delivered by a non-chlorofluorocarbon hydrofluoroalkane (HFA) metered-dose inhaler (MDI). In the lungs, ciclesonide is converted to an active metabolite, which is responsible for the beneficial effects of the drug in patients with asthma. Ciclesonide and its active metabolite have low systemic bioavailability and therefore have a low potential to produce systemic adverse events. Inhaled ciclesonide delivered by HFA-MDI is effective in the prophylactic treatment of persistent asthma in adults, adolescents and children, and is generally well tolerated. In general, ciclesonide improves lung function and reduces asthma symptoms and rescue medication use in adults and adolescents with asthma of varying severity. The drug is generally no less effective than other inhaled corticosteroids with regard to maintaining or improving lung function and may have a more favourable tolerability profile than some other agents in this class. Ciclesonide has also shown efficacy in paediatric patients with asthma. Data on its long-term effects on other clinical outcomes, such as asthma exacerbations, would be of interest. Further comparative and long-term studies would also be beneficial in order to definitively position ciclesonide with respect to other inhaled corticosteroids. In the meantime, ciclesonide offers an effective and well tolerated first-line preventative treatment option for persistent asthma.

Abstract
BACKGROUND Ciclesonide is a new inhaled corticosteroid (ICS). Information about its clinical efficacy and safety in relation to other ICS in children is needed for clinical positioning. OBJECTIVE This 12-week, randomized, double-blind, double-dummy, three-arm, parallel-group study compared the efficacy and safety of ciclesonide with fluticasone propionate in children with mainly moderate and severe persistent asthma. METHODS Seven hundred and forty-four patients (aged 6-11 years) were randomized to ciclesonide (80 or 160 microg once daily) or fluticasone propionate (88 microg twice daily), following a 2-4-week run-in. Efficacy measurements included forced expiratory flow in 1s (FEV(1)), morning peak expiratory flow (PEF), asthma symptom scores, rescue medication use and quality of life. Systemic effect was assessed by 24-hour urine free cortisol adjusted for creatinine. RESULTS FEV(1) and morning PEF increased from baseline in all groups (p<0.0001). Ciclesonide 160 microg was not inferior to fluticasone propionate 176 microg for FEV(1) (p=0.0030, one-sided). In all groups, asthma symptom score sums and rescue medication use significantly improved (p<0.0001). The percentages of asthma symptom-, rescue medication- and nocturnal awakening-free days were high, with no significant differences between treatments. Quality of life scores improved with all treatments (p<0.0001). A significant dose-response occurred between low and higher doses of ciclesonide for exacerbations and asthma control definitions. The incidences of adverse events were comparable across treatments. Urine free cortisol levels decreased significantly with fluticasone propionate (p=0.0103), but not with ciclesonide. CONCLUSION Once-daily ciclesonide has a clinical effect similar to that of fluticasone propionate, but does not suppress cortisol excretion, in children with moderate and severe asthma.

Abstract
Ciclesonide is a novel corticosteroid (CS) for the treatment of asthma and allergic rhinitis. After administration, the parent compound ciclesonide is converted by intracellular airway esterases to its pharmacologically active metabolite desisobutyryl-ciclesonide (des-CIC). We investigated the in vitro activation of ciclesonide and further esterification of des-CIC to (mainly) des-CIC oleate in several human target organ test systems. Human precision-cut lung slices, alveolar type II epithelial cells (A549), normal bronchial epithelial cells (NHBE), and nasal epithelial cells (HNEC) were incubated with ciclesonide. Enzymes characterization and the determination of the reversibility of fatty acid esterification was investigated in HNEC and NHBE. Ciclesonide was taken up and converted to des-CIC in all cellular test systems. Intracellular concentrations of des-CIC were maintained for up to 24 h. Formation of des-CIC oleate increased over time in HNEC, A549 cells, and lung slices. The formed des-CIC fatty acid conjugates were reconverted to des-CIC. Increasing concentrations of carboxylesterase and cholinesterase inhibitors progressively reduced the formation of metabolites. The results derived from these studies demonstrate the activation of ciclesonide to des-CIC in the upper and lower airways. The reversible formation of des-CIC fatty acid conjugates may prolong the anti-inflammatory activity of des-CIC and may allow for once-daily dosing.

Abstract
BACKGROUND Inhaled corticosteroids (ICS) are an integral part of asthma management, and act as an anti-inflammatory agent in the airways of the lung. These agents confer both significant benefit in terms of symptom management and improvement in lung function, but may also cause harm in terms of local and systemic side-effects. Ciclesonide is a novel steroid that is metabolised to its active component in the lung, making it a potentially useful for reducing local side effects. OBJECTIVES To assess the efficacy and adverse effects of ciclesonide relative to those of other inhaled corticosteroids in the management of chronic asthma. SEARCH STRATEGY We searched the Cochrane Airways Group register of trials with pre-defined terms. Additional searches of PubMed and Clinicalstudyresults.org were undertaken. The literature searches for this review are current up to June 2007. SELECTION CRITERIA Randomised parallel or crossover studies were eligible for the review. We included studies comparing ciclesonide with other steroids both at nominally equivalent dose or lower doses of ciclesonide. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial quality and extracted data. Study authors were contacted for additional information. Adverse effects information was collected from the trials. MAIN RESULTS Twenty one trials involving 7243 participants were included. Equal daily doses of ciclesonide and beclomethasone (BDP) or budesonide (BUD) gave similar results for peak expiratory flow rates (PEF), although forced vital capacity (FVC) was higher with ciclesonide. Data on forced expired volume in one second (FEV1) were inconsistent. Withdrawal data and symptoms were similar between treatments. Compared with the same dose of fluticasone (FP), data on lung function parameters (FEV1, FVC and PEF) did not differ significantly. Paediatric quality of life score favoured ciclesonide. Candidiasis was less frequent with ciclesonide, although other side-effect outcomes did not give significant differences in favour of either treatment. When lower doses of ciclesonide were compared to BDP or BUD, the difference in FEV1 did not reach significance but we cannot exclude a significant effect in favour of BDP/BUD. Other lung function outcomes did not give significant differences between treatments. Paediatric quality of life scores did not differ between treatments. Adverse events occurred with similar frequency between ciclesonide and BDP/BUD. Comparison with FP at half the nominal dose was undertaken in three studies, which indicated that FEV1 was not significantly different, but was not equivalent between the treatments (per protocol: -0.05 L 95% confidence intervals -0.11 to 0.01). AUTHORS' CONCLUSIONS The results of this review give some support to ciclesonide as an equivalent therapy to other ICS at similar nominal doses. The studies assessed low doses of steroids, in patients whose asthma required treatment with low doses of steroids. At half the dose of FP and BDP/BUD, the effects of ciclesonide were more inconsistent The effect on candidiasis may be of importance to people who find this to be problematic. The role of ciclesonide in the management of asthma requires further study, especially in paediatric patients. Further assessment against FP at a dose ratio of 1:2 is a priority.

Abstract
BACKGROUND Inhaled corticosteroids are an integral part of asthma management, and act as an anti-inflammatory agent in the airways of the lung. These agents confer significant benefit in terms of symptom management and improvement in lung function, but may also cause harm in terms of local and systemic side-effects. Ciclesonide is a novel steroid that has efficient distribution and release properties that mean it can be taken once daily, making it potentially useful in ongoing asthma management. OBJECTIVES To assess the efficacy of inhaled ciclesonide in adults and children with chronic asthma. SEARCH STRATEGY We searched the Cochrane Airways Group register of trials with pre-defined terms. Additional searches of CENTRAL and PubMed were undertaken. The literature searches for this review are current up to June 2007. SELECTION CRITERIA Randomised parallel or crossover studies were eligible for the review. We included studies comparing ciclesonide with placebo, and we also included studies comparing ciclesonide at different doses. DATA COLLECTION AND ANALYSIS Two authors assessed studies for inclusion in the review, extracted data independently and checked each others' work. We contacted study investigators in order to obtain additional data. Extracted data were entered into RevMan 4.2 and analysed as fixed effect mean differences for continuous data, and fixed effect risk ratios for dichotomous data. MAIN RESULTS Eighteen trials (reporting 20 study comparisons) met the review entry criteria. We report findings from 18 group comparisons where data were available (6343 participants, of whom 1692 were children). Ciclesonide versus placebo: The short duration of the included studies means that there is a lack of data with respect to the impact of ciclesonide on asthma exacerbations. At doses of 100 mcg/d or less up to 400 mcg/d in mild to moderate asthma, ciclesonide improved lung function, asthma symptoms and rescue inhaler use, compared with placebo.Dose response outcomes: Comparisons of 100 versus 200 mcg/d, 100 versus 400 mcg/d and 400 versus 800 mcg/d did not yield significant differences in lung function outcomes. Adverse event data were not available in sufficient detail to permit assessment of the safety profile of this drug. AUTHORS' CONCLUSIONS Ciclesonide was more effective than placebo, in the short term, in improving lung function in patients with mild to moderate asthma previously treated with inhaled corticosteroids. There remain questions as to dose response, and the lack of data on the longer term impact on exacerbations and safety profile should be addressed in future studies.

Abstract
This 12-week, double-blind, parallel-group study compared the efficacy and safety of once daily ciclesonide and twice daily fluticasone propionate in patients aged 12-75 years with persistent asthma. Patients were randomized to once-daily ciclesonide 80 micro g (n = 278) or 160 micro g (n = 271), or twice daily fluticasone propionate 88 micro g (n = 259) (all ex-actuator). Significant improvements from baseline were seen in all three treatment groups for forced expiratory volume in 1 second, asthma symptom scores and rescue medication use (all p < 0.0001). Asthma exacerbation rates were low (each ciclesonide group, n = 2; fluticasone group, n = 1). Adverse event reporting indicated good tolerability. Once daily ciclesonide 80 micro g or 160 micro g showed comparable efficacy and tolerability to twice daily fluticasone propionate 88 micro g in persistent asthma.

Abstract
OBJECTIVE Demonstrating clinical benefit of higher doses of inhaled corticosteroids in asthma is frequently problematic owing to their relatively flat dose-response curve in this condition. In this study we compared the efficacy and safety of a fourfold difference in the dose of ciclesonide-ciclesonide 320 microg twice daily (CIC640) versus ciclesonide 160 microg once daily (CIC160)-in patients with severe persistent asthma. METHODS Patients with bronchial asthma (6 months) were included in this randomized, double-blind study. After receiving fluticasone propionate 250 microg twice daily during run-in, patients were randomized to CIC160 (n=339) or CIC640 (n=341) for 12 weeks. Primary endpoints were time to first asthma exacerbation and forced expiratory volume in 1s (FEV(1)). Secondary endpoints included other lung function variables, asthma symptom scores and rescue medication use (RMU). RESULTS Asthma exacerbations occurred in 12.7% of patients receiving CIC160 and 6.7% receiving CIC640. CIC640 was superior for time to first exacerbation (p=0.0050, one-sided). FEV(1) increased significantly with CIC160 and CIC640 (least squares mean+/-SE of mean: 269+/-31 and 332+/-31 mL, respectively; p<0.0001), with no significant difference between groups. Change in % predicted FEV(1) and morning peak expiratory flow (PEF) were significantly higher with CIC640 (p<0.05). Asthma symptom score sums and RMU decreased in both groups; CIC640 was statistically superior (p=0.0108 and 0.0005, respectively). No unexpected adverse events were reported in either group and the majority of the events reported were mild or moderate in intensity. No significant changes in serum cortisol were observed from the baseline to the study end. Small decreases in creatinine-adjusted 24h urine cortisol levels from baseline were seen in both the treatment groups, which, due to the large patient numbers, were statistically significant (p<0.05); however, no dose-response effect was seen and the difference between groups was not significant (p=0.7892). CONCLUSION CIC640 was superior to CIC160 for time to first exacerbation, % predicted FEV1, morning PEF, asthma symptom score sum and RMU in patients with severe asthma; both doses had similar tolerability profiles and no significant changes in serum cortisol were seen in either treatment group.

Abstract
Background Ciclesonide is a novel inhaled corticosteroid for the treatment of airway inflammation. In this study we investigated uptake and in vitro metabolism of ciclesonide in human alveolar type II epithelial cells (A549). Ciclesonide uptake was compared with fluticasone propionate, an inhaled corticosteroid that is not metabolized in lung tissue. A549 cells were incubated with 2 × 10-8 M ciclesonide or fluticasone propionate for 3 to 30 min to determine uptake; or with 2 × 10-8 M ciclesonide for 1 h, followed by incubation with drug-free buffer for 3, 6, and 24 h to analyze in vitro metabolism. High performance liquid chromatography with tandem mass spectrometry was used to measure the concentrations of both corticosteroids and metabolites. Results At all time points the mean intracellular concentration was higher for ciclesonide when compared with fluticasone propionate. Activation of ciclesonide to desisobutyryl-ciclesonide (des-CIC) was confirmed and conjugates of des-CIC with fatty acids were detected. The intracellular concentration of ciclesonide decreased over time, whereas the concentration of des-CIC remained relatively stable: 2.27 to 3.19 pmol/dish between 3 and 24 h. The concentration of des-CIC fatty acid conjugates increased over time, with des-CIC-oleate being the main metabolite. Conclusion Uptake of ciclesonide into A549 cells was more efficient than that of the less lipophilic fluticasone propionate. Intracellular concentrations of the pharmacologically active metabolite des-CIC were maintained for up to 24 h. The local anti-inflammatory activity of ciclesonide in the lung may be prolonged by the slow release of active drug from the depot of fatty acid esters.

Abstract
Background The therapeutic effect of inhaled corticosteroids (ICS) may be affected by the metabolism of the drug in the target organ. We investigated the in vitro metabolism of beclomethasone dipropionate (BDP), budesonide (BUD), ciclesonide (CIC), and fluticasone propionate (FP) in human lung precision-cut tissue slices. CIC, a new generation ICS, is hydrolyzed by esterases in the upper and lower airways to its pharmacologically active metabolite desisobutyryl-ciclesonide (des-CIC). Methods Lung tissue slices were incubated with BDP, BUD, CIC, and FP (initial target concentration of 25 μM) for 2, 6, and 24 h. Cellular viability was assessed using adenosine 5'-triphosphate content and protein synthesis in lung slices. Metabolites and remaining parent compounds in the tissue samples were analyzed by HPLC with UV detection. Results BDP was hydrolyzed to the pharmacologically active metabolite beclomethasone-17-monopropionate (BMP) and, predominantly, to inactive beclomethasone (BOH). CIC was hydrolyzed initially to des-CIC with a slower rate compared to BDP. A distinctly smaller amount (approximately 10-fold less) of fatty acid esters were formed by BMP (and/or BOH) than by BUD or des-CIC. The highest relative amounts of fatty acid esters were detected for BUD. For FP, no metabolites were detected at any time point. The amount of drug-related material in lung tissue (based on initial concentrations) at 24 h was highest for CIC, followed by BUD and FP; the smallest amount was detected for BDP. Conclusion The in vitro metabolic pathways of the tested ICS in human lung tissue were differing. While FP was metabolically stable, the majority of BDP was converted to inactive polar metabolites. The formation of fatty acid conjugates was confirmed for BMP (and/or BOH), BUD, and des-CIC.

Abstract
The role of airway clearance in inhaled drug therapy is complex. Disease-induced bronchoconstriction results in a central drug-deposition pattern where mucociliary clearance is most efficient. When drug-induced bronchodilation is achieved, deposition and uptake becomes more peripheral, and because there is less mucociliary clearance in the periphery, this will lead to an unintentional increase in lung exposure and enhance the risk of systemic side effects. In addition, mucociliary clearance is pathologically reduced in both asthma and chronic obstructive pulmonary disease. Among inhaled corticosteroids, rate of dissolution and lung uptake differs considerably. For the slowly dissolving, lipophilic steroids, the contribution of mucociliary clearance to these findings appears significant, and variability in lung and systemic exposure resulting from variable mucociliary function appears to be amplified. In addition, dose optimisation of non-stable asthma becomes more complex. The present review highlights the impact of mucociliary clearance on inhaled corticosteroid disposition and identifies critical areas where more research is needed.

Abstract
Study of the chronobiology of allergic rhinitis (AR) and bronchial asthma (BA) and the chronopharmacology and chronotherapy of the medications used in their treatment began five decades ago. AR is an inflammatory disease of the upper airway tissue with hypersensitivity to specific environmental antigens, resulting in further local inflammation, vasomotor changes, and mucus hypersecretion. Symptoms include sneezing, nasal congestion, and runny and itchy nose. Approximately 25% of children and 40% of adults in USA are affected by AR during one or more seasons of the year. The manifestation and severity of AR symptoms exhibit prominent 24-h variation; in most persons they are worse overnight or early in the morning and often comprise nighttime sleep, resulting in poor daytime quality of life, compromised school and work performance, and irritability and moodiness. BA is also an inflammatory medical condition of the lower airways characterized by hypersensitivity to specific environmental antigens, resulting in greater local inflammation as well as bronchoconstriction, vasomotor change, and mucus hypersecretion. In USA an estimated 6.5 million children and 15.7 million adults have BA. The onset and worsening of BA are signaled by chest wheeze and/or croupy cough and difficult and labored breathing. Like AR, BA is primarily a nighttime medical condition. AR is treated with H1-antagonist, decongestant, and anti-inflammatory (glucocorticoid and leukotriene receptor antagonist and modifier) medications. Only H1-antagonist AR medications have been studied for their chronopharmacology and potential chronotherapy. BA is treated with some of the same medications and also theophylline and beta2-agonists. The chronopharmacology and chronotherapy of many classes of BA medications have been explored. This article reviews the rather extensive knowledge of the chronobiology of AR and BA and the chronopharmacology and chronotherapy of the various medications used in their treatment.

Abstract
Ciclesonide is an onsite-activated inhaled corticosteroid (ICS) for the treatment of asthma. This study compared the efficacy, safety and effect on quality of life (QOL) of ciclesonide 160 microg (ex-actuator; nominal dose 200 microg) vs. budesonide 400 microg (nominal dose) in children with asthma. Six hundred and twenty-one children (aged 6-11 yr) with asthma were randomized to receive ciclesonide 160 microg (ex-actuator) once daily (via hydrofluoroalkane metered-dose inhaler and AeroChamber Plus spacer) or budesonide 400 microg once daily (via Turbohaler) both given in the evening for 12 wk. The primary efficacy end-point was change in forced expiratory volume in 1 s (FEV1). Additional measurements included change in daily peak expiratory flow (PEF), change in asthma symptom score sum, change in use of rescue medication, paediatric and caregiver asthma QOL questionnaire [PAQLQ(S) and PACQLQ, respectively] scores, change in body height assessed by stadiometry, change in 24-h urinary cortisol adjusted for creatinine and adverse events. Both ciclesonide and budesonide increased FEV1, morning PEF and PAQLQ(S) and PACQLQ scores, and improved asthma symptom score sums and the need for rescue medication after 12 wk vs. baseline. The non-inferiority of ciclesonide vs. budesonide was demonstrated for the change in FEV1 (95% confidence interval: -75, 10 ml, p = 0.0009, one-sided non-inferiority, per-protocol). In addition, ciclesonide and budesonide showed similar efficacy in improving asthma symptoms, morning PEF, use of rescue medication and QOL. Ciclesonide was superior to budesonide with regard to increases in body height (p = 0.003, two-sided). The effect on the hypothalamic-pituitary-adrenal axis was significantly different in favor of ciclesonide treatment (p < 0.001, one-sided). Both ciclesonide and budesonide were well tolerated. Ciclesonide 160 microg once daily and budesonide 400 microg once daily were effective in children with asthma. In addition, in children treated with ciclesonide there was significantly less reduction in body height and suppression of 24-h urinary cortisol excretion compared with children treated with budesonide after 12 wk.

Abstract
The role of inhaled corticosteroids (ICS) in the treatment of childhood asthma has been well established. An ideal corticosteroid should demonstrate high pulmonary deposition and residency time, in addition to a low systemic bioavailability and rapid systemic clearance. The lung depositions of the ICS have been compared, with beclomethasone (beclometasone)-hydrofluoroalkane (HFA) and ciclesonide showing the highest lung deposition. Lung deposition is influenced by not only the inhalation device and type of propellant (HFA or chlorofluorocarbon), but also by whether the aerosol is a solution or suspension, and the particle size of the respirable fraction. Pulmonary residency time increases when budesonide and des-ciclesonide undergo reversible fatty acid esterification. The bioavailability of the drug depends on the oral bioavailable fraction and the amount absorbed directly from the pulmonary vasculature. The clearance rate of des-ciclesonide is very high (228 L/h), increasing its safety profile by utilizing extra-hepatic clearance mechanisms. Both des-ciclesonide and mometasone have a high protein binding fraction (98-99%). The volume of distribution (Vd) is proportional to the lipophilicity of the drug, with the Vd of fluticasone being 332L compared with 183L for budesonide. Increasing the Vd will also increase the elimination half-life of a drug. The pharmacodynamics of ICS depend on both the receptor binding affinity and the dose-response curve. Among the ICS, fluticasone and mometasone have the highest receptor binding affinity (1800 and 2200, respectively), followed by budesonide at 935 (relative to dexamethasone = 100). Compared with other nonsteroid asthma medications (long-acting beta-agonists, theophylline, and montelukast) ICS have proven superiority in improving lung function, symptom-free days, and inflammatory markers. One study suggests that early intervention with ICS reduces the loss in lung function (forced expiratory volume in 1 second) over 3 years. Whether airway remodeling is reduced or prevented in the long term is unknown. Potential adverse drug effects of ICS include adrenal and growth suppression. While in low-to-medium doses ICS have shown little suppression of the adrenal pituitary axis, in high doses the potential for significant adrenal suppression and adrenal crisis exists. Several longitudinal studies evaluating the effect of ICS on growth have shown a small decrement in growth velocity (approximate 1-2 cm) during the first year of treatment. However, when investigators followed children treated with budesonide for up to 10 years, no change in target adult height was noted. In conclusion, the development of optimal delivery devices for young children, as well as optimizing favorable pharmacokinetic properties of ICS should be priorities for future childhood asthma management.

Abstract
The in vitro metabolism of ciclesonide, a novel inhaled nonhalogenated glucocorticoid for the treatment of asthma, was compared in cryopreserved hepatocytes from mice, rats, rabbits, dogs, and humans. Incubations of C-ciclesonide with individual hepatocyte suspensions revealed similar metabolite profiles in all 5 in vitro systems used. Ciclesonide was rapidly converted to its active metabolite, desisobutyryl-ciclesonide (des-CIC). Des-CIC was then extensively metabolized to pharmacologically inactive metabolites through oxidation and reduction, followed by glucuronidation. A total of 12 groups of metabolites derived from des-CIC were characterized and identified by liquid chromatography/radioactivity monitor/mass spectrometry. Oxidation occurred on both the cyclohexane ring and the steroid moiety. Hippuric acid formation by cleavage of the cyclohexylmethyl moiety of ciclesonide, followed by aromatization of the cyclohexane ring through multiple steps of hydroxylation, dehydration, and conjugation with glycine, was found in rat, rabbit, and human hepatocyte incubations. The results indicated that ciclesonide and its active metabolite, des-CIC, were extensively metabolized in vitro in animal and human hepatocytes and that the metabolite profiles in mouse, rat, rabbit, and dog hepatocytes were similar to the profiles in human hepatocytes.

Abstract
BACKGROUND The aim of the study was to investigate the efficacy and safety of ciclesonide compared with budesonide in adolescents with severe asthma. METHODS In this randomized, double-blind, double-dummy, parallel-group study, patients aged 12-17 years with severe asthma were treated with budesonide 400 microg once daily (QD) in a 2-week run-in period. At randomization, eligible patients were assigned 2:1 to ciclesonide 320 microg QD (ex-actuator) or budesonide 800 microg QD (metered dose), respectively, in the evening. Forced expiratory volume in 1s (FEV(1)) was the primary variable. Patients recorded asthma symptom score and rescue medication use in diaries. Safety assessments included adverse events (AEs) and 24-h urine cortisol. RESULTS Four hundred and three patients were randomized. Ciclesonide 320 microg QD and budesonide 800 microg QD significantly increased FEV(1) (least-squares mean: 505 and 536 mL, respectively; both p<0.0001 versus baseline) in the intention-to-treat (ITT) population. Lower limits of the 95% confidence intervals (ITT: -138 mL; per-protocol: -122 mL) were above the non-inferiority limit (-150 mL). Median percentage of days without asthma symptoms and without rescue medication use was 84% with ciclesonide and 85% with budesonide. AEs were unremarkable, with no cases of confirmed candidiasis. Median creatinine-adjusted urine cortisol significantly decreased with budesonide treatment (15.9-13.7 nmol cortisol/mmol creatinine; p=0.0086 versus baseline), but not with ciclesonide (p=0.1125). CONCLUSIONS Ciclesonide 320 microg QD showed similar efficacy to budesonide 800 microg QD in adolescents with severe asthma. Ciclesonide was well tolerated and, unlike budesonide, had no effect on urine cortisol levels. CLINICAL TRIAL REGISTRATION NUMBER EudraCT No.: 2004-001233-41.

Abstract
OBJECTIVE To investigate the relative efficacy of ciclesonide and fluticasone propionate (FP) administered at comparable microgram doses in maintaining asthma control in patients with moderate-to-severe persistent asthma. METHODS This randomized, open-label, parallel-group study enrolled patients aged 12-75 years with a 6-month history of bronchial asthma. To enter a 2-week run-in period, patients had to have received FP 500-1000 microg/day or equivalent at a stable dose for 4 weeks and have a forced expiratory volume in 1s (FEV 1) 80% of predicted. To enter the treatment period, patients had to have the following during run-in: FEV 1 80% of predicted; reversibility of Delta FEV 1 12% after 200-400 microg salbutamol; and 1 day without asthma symptoms during the last 7 days. Patients were randomized to twice-daily ciclesonide 320 microg (ex-actuator) or twice-daily FP 330 microg (ex-actuator) for 6 months. Efficacy was assessed by lung function, asthma exacerbations, asthma symptoms and rescue medication use. Patients completed the standardized version of the Asthma Quality of Life Questionnaire (AQLQ[S]). Adverse events (AEs), including local oropharyngeal AEs, were recorded. RESULTS 528 patients were randomized (ciclesonide, n=255; FP, n=273). In both groups, FEV 1 was maintained from baseline to study end (mean increase: ciclesonide 11 mL, FP 24 mL; intention-to-treat [ITT] analysis). The least squares mean+/-standard error of the mean for the treatment difference was -13+/-29 (95% confidence interval [CI]: -70, 44) in the ITT analysis and -27+/-34 (95% CI: -93, 40) in the per-protocol (PP) analysis, demonstrating non-inferiority of ciclesonide to FP. Morning, evening and site-measured PEF improved significantly with both treatments (ITT and PP analyses: p<0.05). Six patients receiving ciclesonide and seven receiving FP (ITT analysis) experienced an asthma exacerbation requiring treatment with oral corticosteroids. Both treatments significantly decreased asthma symptom score sum (ITT and PP analyses: p0.0001) and rescue medication use (ITT and PP analyses: p<0.05), with no significant difference between treatments. Both treatments significantly improved overall AQLQ(S) score (ITT and PP analyses: p<0.05). Significantly more patients experienced candidiasis and dysphonia with FP compared with ciclesonide (p=0.0023). CONCLUSION Ciclesonide 320 microg and FP 330 microg administered twice daily over 6 months provided similar efficacy in patients with moderate or severe persistent asthma previously well-controlled by high doses of ICS at baseline. Ciclesonide was associated with fewer local AEs than FP.

Abstract
OBJECTIVE To compare the effects of once-daily ciclesonide and twice-daily fluticasone propionate in patients with moderate persistent asthma. METHODS Patients aged 12-75 years with moderate bronchial asthma entered a 1-4 week run-in period. For inclusion into the 12-week, randomized, open-label treatment period, patients had to have a forced expiratory volume in 1s (FEV1) of either 60-80% of predicted or 80% of predicted and a defined use of rescue medication and asthma symptoms, depending on previous treatment. Patients received ciclesonide 320 microg once daily (ex-actuator) or fluticasone propionate 200 microg twice daily. Primary efficacy endpoint was change from baseline in FEV1. RESULTS In total, 474 patients were randomized. FEV1 increased significantly from baseline with ciclesonide and fluticasone propionate in the intention-to-treat (ITT) and per-protocol (PP) analyses (all p < 0.0001). Treatment difference was -31 mL (95% confidence interval [CI]: -121, 59) in the PP analysis, demonstrating non-inferiority of ciclesonide. Similar findings were seen for other measures of lung function. In the ITT population, asthma symptom scores and rescue medication use decreased with both treatments (all p < 0.0001). Improvement in health-related quality of life (HRQoL) from baseline was significantly greater with ciclesonide than fluticasone (p = 0.005; one-sided). There were no cases of oral candidiasis in patients receiving ciclesonide and nine cases (3.8%) in those receiving fluticasone propionate (p = 0.002; one-sided). CONCLUSIONS Treatment with once-daily ciclesonide and twice-daily fluticasone propionate resulted in similar improvements in lung function in patients with moderate persistent asthma. Ciclesonide showed significant improvements in oral candidiasis and HRQoL over fluticasone.
