Project description:BackgroundAn increase in serious adverse events with both regular formoterol and regular salmeterol in chronic asthma has been demonstrated in comparison with placebo in previous Cochrane reviews. This increase was significant in trials that did not randomise participants to an inhaled corticosteroid, but less certain in the smaller numbers of participants in trials that included an inhaled corticosteroid in the randomised treatment regimen.ObjectivesWe set out to compare the risks of mortality and non-fatal serious adverse events in trials which have randomised patients with chronic asthma to regular formoterol versus regular salmeterol, when each are used with an inhaled corticosteroid as part of the randomised treatment.Search strategyTrials were identified using the Cochrane Airways Group Specialised Register of trials. Manufacturers' web sites of clinical trial registers were checked for unpublished trial data and Food and Drug Administration (FDA) submissions in relation to formoterol and salmeterol were also checked. The date of the most recent search was July 2009.Selection criteriaControlled clinical trials with a parallel design, recruiting patients of any age and severity of asthma were included if they randomised patients to treatment with regular formoterol versus regular salmeterol (each with a randomised inhaled corticosteroid), and were of at least 12 weeks duration.Data collection and analysisTwo authors independently selected trials for inclusion in the review and extracted outcome data. Unpublished data on mortality and serious adverse events were sought from the sponsors and authors.Main resultsEight studies met the eligibility criteria of the review recruiting 6,163 adults and adolescents. There were seven studies (involving 5,935 adults and adolescents) comparing formoterol and budesonide to salmeterol and fluticasone. All but one study administered the products as a combined inhaler, and most used formoterol 50 mcg and budesonide 400 mcg twice daily versus salmeterol 50 mcg and fluticasone 250 mcg twice daily. There were two deaths overall (one on each combination) and neither were thought to be related to asthma.There was no significant difference between treatment groups for non-fatal serious adverse events, either all-cause (Peto OR 1.14; 95% CI 0.82 to 1.59, I(2) = 26%) or asthma-related (Peto OR 0.69; 95% CI 0.37 to 1.26, I(2) = 33%). Over 23 weeks the rates for all-cause serious adverse events were 2.6% on formoterol and budesonide and 2.3% on salmeterol and fluticasone, and for asthma-related serious adverse events, 0.6% and 0.8% respectively.There was one study (228 adults) comparing formoterol and beclomethasone to salmeterol and fluticasone, but there were no deaths or hospital admissions.No studies were found in children.Authors' conclusionsThe seven identified studies in adults did not show any significant difference in safety between formoterol and budesonide in comparison with salmeterol and fluticasone. Asthma-related serious adverse events were rare, and there were no reported asthma-related deaths. There was a single small study comparing formoterol and beclomethasone to salmeterol and fluticasone in adults, but no serious adverse events occurred in this study. No studies were found in children.Overall there is insufficient evidence to decide whether regular formoterol and budesonide or beclomethasone have equivalent or different safety profiles from salmeterol and fluticasone.

Project description:BACKGROUND: Addition of the long acting beta2 agonist salmeterol to inhaled corticosteroids leads to better symptomatic asthma control than increasing the dose of inhaled corticosteroids. However, little is known about the long term effects of adding salmeterol on the asthmatic inflammatory process, control of which is considered important for the long term outcome of asthma. METHODS: After a 4 week fluticasone run-in period, 54 patients with allergic asthma were randomised to receive twice daily treatment with fluticasone 250 microg with or without salmeterol 50 microg for 1 year in a double blind, parallel group design (total daily dose of fluticasone 500 microg in both treatment groups). Primary outcomes were sputum eosinophil numbers and eosinophil cationic protein concentrations. Secondary outcomes were neutrophil associated sputum parameters and a respiratory membrane permeability marker. The effects on allergen induced changes were determined before and at the end of the treatment period. RESULTS: Adding salmeterol to fluticasone resulted in improved peak expiratory flow, symptom scores, rescue medication usage, and bronchial hyperresponsiveness (p < 0.05 for all). There was no sustained effect on sputum cell differential counts and cytokine concentrations during the treatment period or on changes induced by allergen challenge at the end of treatment (p > 0.05). However, adding salmeterol significantly reduced sputum ratios of alpha2-macroglobulin and albumin during the treatment period (p = 0.001). CONCLUSIONS: The addition of salmeterol to fluticasone produces no sustained effect on allergen induced cellular bronchial inflammation but leads to a significant improvement in size selectivity of plasma protein permeation across the respiratory membrane. This may contribute to the improved clinical outcome seen in patients with allergic asthma when a long acting beta2 agonist is combined with inhaled corticosteroids.

Project description:BackgroundCystic fibrosis (CF) is an autosomal recessive disease characterized by chronic sinopulmonary symptoms and chronic gastrointestinal symptoms that begins in infancy. Children with CF are increasingly being included in clinical trials. In order to fully evaluate the impact of new therapies in future clinical trials, an understanding of baseline adverse event (AE) rates in children with CF is needed. To address this, we determined the rates of common AEs in pediatric patients with CF who participated in two clinical trials.MethodsWe reviewed AEs for placebo recipients in the AZ0004 study and inhaled tobramycin recipients in the Early Pseudomonas Infection Control (EPIC) clinical trial. AEs were categorized based on Medical Dictionary for Regulatory Activities (MedDRA) coding classifications and pooled into common, batched AE descriptors. AE rates were estimated from negative binomial models according to age groups, severity of lung disease, and season.ResultsA total of 433 children had 8,266 total AEs reported, or 18.1 (95% CI 17.0, 19.2) AEs per person per year. Respiratory AEs were the most commonly reported AEs, with a rate of 7.6 events per person-year. The total SAE rate was 0.33 per person per-year. Cough was the most commonly reported respiratory AE, with 61% of subjects reporting at least one episode of cough within 4 months. The rate ratio of any AE was higher in Spring, Fall, and Winter, compared with Summer.ConclusionsAEs occur commonly in pediatric CF clinical trial participants. Season of enrollment could affect AE rates.

Project description:BackgroundThe efficacy of inhaled corticosteroids (ICSs)/long-acting beta2-agonist (LABA) treatment in patients with asthma-chronic obstructive pulmonary disease (COPD) overlap syndrome (ACOS) compared to patients with COPD alone has rarely been examined. This study aimed to evaluate the clinical efficacy for the improvement of lung function after ICS/LABA treatment in patients with ACOS compared to COPD alone patients.MethodsPatients with stable COPD were selected from the Korean Obstructive Lung Disease (KOLD) cohort. Subjects began a 3-month ICS/LABA treatment after a washout period. ACOS was defined when the patients had 1) a personal history of asthma, irrespective of age, and wheezing in the last 12 months in a self-reported survey and 2) a positive bronchodilator response.ResultsAmong 152 eligible COPD patients, 45 (29.6%) fulfilled the criteria for ACOS. After a 3-month treatment with ICS/LABA, the increase in forced expiratory volume in 1 second (FEV1) was significantly greater in ACOS patients than in those with COPD alone (240.2±33.5 vs 124.6±19.8 mL, P=0.002). This increase in FEV1 persisted even after adjustment for confounding factors (adjusted P=0.002). According to severity of baseline FEV1, the ACOS group showed a significantly greater increase in FEV1 than the COPD-alone group in patients with mild-to-moderate airflow limitation (223.2±42.9 vs 84.6±25.3 mL, P=0.005), whereas there was no statistically significant difference in patients with severe to very severe airflow limitation.ConclusionThis study provides clinical evidence that ACOS patients with mild-to-moderate airflow limitation showed a greater response in lung function after 3 months of ICS/LABA combination treatment.

Project description:Ruxolitinib (INCB018424) is a JAK1 and JAK2 inhibitor recently evaluated for the treatment of myelofibrosis (MF) in early- and advanced-phase clinical trials. In 2 recent communications that focused on short-term and long-term ruxolitinib treatment outcome, respectively, the drug was shown to be effective in controlling constitutional symptoms and splenomegaly but was also associated with important adverse effects, including moderate to severe thrombocytopenia and anemia. The most recent of the 2 communications focused on 51 Mayo Clinic patients who participated in the original phase 1/2 ruxolitinib clinical trial and highlighted a high treatment discontinuation rate (92% after a median time of 9.2 months), primarily for loss of treatment benefit but also because of drug-associated adverse effects. The report also discussed the occurrence of sometimes severe withdrawal symptoms during ruxolitinib treatment discontinuation. This "ruxolitinib withdrawal syndrome" was characterized by acute relapse of disease symptoms, accelerated splenomegaly, worsening of cytopenias, and occasional hemodynamic decompensation, including a septic shocklike syndrome. In the current sponsor-independent analysis, we describe the details of these events in 5 severely affected cases (11%) among 47 Mayo Clinic patients with MF in whom ruxolitinib therapy had been discontinued. Our experience calls for full disclosure of the ruxolitinib withdrawal syndrome to patients with MF before initiating ruxolitinib therapy, and treatment discontinuation must be done under close physician supervision and preferably in a tapering schedule.
