Filter by:The aim of the study is to compare the effects of ciclesonide inhaled at one dose level twice daily versus fluticasone propionate inhaled at one dose level twice daily versus placebo, on short-term lower leg growth in prepubertal children with mild persistent asthma. The study duration consists of a baseline period (2 weeks), a treatment period (2 weeks for each treatment), and a wash-out period (2 weeks). The study will provide further data on safety and tolerability of ciclesonide.
The aim of the study is to compare the efficacy of ciclesonide versus fixed combination of fluticasone propionate/salmeterol versus placebo, on long-term asthma control in patients with mild persistent asthma. The study duration consists of a baseline period (2 weeks) and a treatment period (12 months). The study will provide further data on safety and tolerability of ciclesonide.
The aim of this study is to evaluate the involvement of small airways in asthma, as determined by bronchial challenges, CT-scanning, and cellular markers of inflammation. Ciclesonide will be inhaled at one dose level once daily. The study duration consists of a baseline period (2 to 3 weeks) and a treatment period (5 to 6 weeks). The study will provide further data on safety and tolerability of ciclesonide.
The aim of the study is to investigate the effect of ciclesonide versus fluticasone propionate versus placebo on airway hyperresponsiveness and on the hypothalamic-pituitary-adrenal axis (HPA axis). Treatment medication will be administered as follows: ciclesonide or fluticasone propionate will be inhaled twice daily, using one of the two dose levels. The study duration consists of a baseline period (4 to 6 weeks), five treatment periods (9 days each), and a washout period between treatments (4 to 12 weeks). The study will provide further data on safety and tolerability of ciclesonide.
The aim of the study is to compare the safety and efficacy of ciclesonide versus fluticasone propionate on the lung function, symptoms, use of rescue medication, and occurrence of side effects (such as candidiasis, hoarseness) in adults with persistent asthma. Ciclesonide will be inhaled twice daily at one dose level; fluticasone propionate will be inhaled twice daily at one dose level. The study duration consists of a baseline period (2 weeks) and a treatment period (24 weeks). The study will provide further data on safety and tolerability of ciclesonide.
The aim of this study is to compare the efficacy of ciclesonide with respect to reduction of the number of asthma exacerbations in children with mild persistent asthma. Treatment medication will be administered as follows: ciclesonide will be inhaled once daily, using one of the two dose levels versus placebo together with other corticosteroids used as intermittent treatment. The study duration consists of a baseline period (3 to 4 weeks) and a treatment period (12 months). The study will provide further data on safety and tolerability of ciclesonide.
This randomized, double-blind, placebo-controlled trial assessed the efficacy of montelukast in the treatment of adults ≥50 years of age with persistent asthma and/or COPD. Primary outcomes included forced expiratory volume in one-second (FEV1) and daytime asthma symptoms scores. Nocturnal symptoms, asthma control, health-related quality of life, peak flow measurements, and health care utilization were also assessed as secondary outcomes. Participants were recruited from the Kaiser Permanente Northwest member population. One hundred forty-nine subjects were randomized to treatment with montelukast (10 mg per day) or placebo, and were followed for a six-week period. No differences in lung function measures, health-related quality of life, health care utilization, and asthma symptom scores were observed; however, the montelukast group had slightly improved asthma control scores compared to the placebo group.
The purpose of this study is to find out if omalizumab is effective in treating non-allergic asthma. The US Food and Drug Administration has approved the use of omalizumab to treat moderate to severe allergic asthma.
The role played by ß2AR polymorphisms in determining the bronchial response to ß2AR agonist drugs, has been confirmed by several studies. The purpose of the present study is to examine possible causal relationships between genetically based alteration in the structure of ß2AR and drug responsiveness. An ex-vivo model (organ bath technique) will be used to investigate association between polymorphisms in the coding region of ß2AR and the response of bronchial rings derived from human lung tissue to the respective agonists (i.e. salbutamol). In the second part of the study the same bronchial rings will be incubated for 24 hours in a solution containing fixed concentration of albuterol. A second dose response curve for rising concentrations of albuterol will be constructed and a relationship between β2 genetic polymorphisms and the extent of desensitization to albuterol will be investigated. In addition, through specifically designed receptor binding assay the bronchial tissue will be used to define the affinity (Kd) and expression (Vmax) of the ß2 receptor. These data will enable to enhance our understanding regarding the mechanism responsible for the association noted between ß2AR polymorphism and altered drug effect.
The response to salbutamol varies greatly among individuals. Data from previous studies indicate that some of the variability is accounted for by genetic polymorphisms in the gene encoding for the adrenoceptor subtype β2. The current study was designed to evaluate variability in the response to salbutamol among recently diagnosed patients who have not been treated by β2 agonists or corticosteroids. Lung function tests will be performed prior to and following a single dose administration of salbutamol through inhalation. Additional pharmacodynamic indices will be monitored including pulse and blood pressure. Three samples of plasma will be drawn for the evaluation of salbutamol plasma concentration.
