Active clinical trials for "Asthma"

A phase III study, multicenter, randomized, parallel, open, two-period, comparative non-inferiority of Eurofarma versus Alenia® in the treatment of moderate to severe persistent asthma with and without obstructive pulmonary disease (COPD). ⚠️study will only be conducted in research centers in Brazil (please do not send e-mail if your center is outside brazil).

To test the preliminary efficacy of the TASC adherence promotion intervention for adolescents with asthma in a feasibility randomized controlled trial compared to treatment as usual control arm.

Patients with obese late onset (after childhood) asthma can have lower FeNO levels, yet be highly symptomatic and poorly responsive to inhaled steroids. This is a common asthma phenotype, particularly among females. This reduction of NO occurs through increased arginase activity and uncoupling of NO synthase (NOS), by accumulation of asymmetric di-methyl arginine (ADMA), which further lowers the L-arginine/ADMA ratio, preferentially promoting reactive oxygen species (ROS) formation and inflammation at the expense of NO. Indeed, in patients with obese late onset asthma, lower L-arginine/ADMA plasma ratios are associated with reduced FeNO, increased bronchial hyperreactivity, and greater asthma morbidity. In our pilot studies, the administration of L-citrulline, as an L-arginine donor, to patients with obese late onset asthma increased the L-arginine/ADMA ratio, FeNO levels, and improved asthma control and lung function. Therefore, the objectives of the protocol are to: a) determine the efficacy of L-citrulline, as an add-on treatment to improve the asthma control and lung function in obese late onset asthmatics; b) leverage the use of asthmatic and control cells to further understand obesity-related changes in epithelial airway NO metabolism, and how these changes relate to bronchoconstriction and lung function, c) determine airway epithelial changes in mitochondrial function and bioenergetics in obese late onset asthmatics and how these are modified by L-citrulline. To do this, 54 obese late onset asthmatics with suboptimal control will be blindly randomized, in a cross over study, comparing 15g/day of L-citrulline vs. placebo, in two 8-week treatment periods with a 6-week washout in between. The co-primary study outcomes are asthma control (ACQ, ACT) and FeNO, and secondary endpoints plasma L-arginine/ADMA, FEV1 and PC20 methacholine. Parallel to this study, a small study of 10 healthy obese controls will receive open label L-citrulline for 7 weeks to establish comparative reference values for the study aims. During the initial treatment phase, 50% of study participants will be randomly allocated to undergo pre and post L-citrulline treatment bronchoscopy to obtain BAL and airway epithelial cells. The research group proposing this study is highly experience in asthma clinical trials, implementation of cross over design studies, and in the use of research bronchoscopies.

This is a phase II, multicenter, double-blind, randomized, parallel group, placebo-controlled clinical study to evaluate the effect of three doses of TQC2731 on Annualized Asthma Exacerbation Rates(AAER) in adult subjects with poor control of severe asthma. It is estimated that 220 subjects will be included. The subjects will receive TQC2731 (70 mg Q4w, 210 mg Q4w, 420 mg Q4w) or placebo (Q4w) administered by Subcutaneous (SC) in the ratio of 1:1:1:1. The study comprised a 5 to 6-week screening period, a 52-week treatment period and a 12-week follow-up period. During the treatment period, the study drug will be administered from day 0 until week 48. The study drug was not administered at the 52nd week.

The purpose of this study is to evaluate the superiority in terms of efficacy and evaluate the safety of QMF149 (indacaterol (acetate) / mometasone (furoate)) compared to budesonide in children from 6 to less than 12 years of age with asthma. The study duration will be up to 37 weeks including an investigational treatment duration of 12 weeks and a comparator treatment duration of 12 weeks. The visit frequency will be 3 weeks for screening, run-in and wash-out period, 6 weeks interval for visits during each treatment period, 30 days for safety follow-up.

The purpose of this open-label 12-month extension study is to continue to characterize the long-term safety, efficacy and immunogenic profile of GSK3511294 (Depemokimab) in participants with severe asthma with an eosinophilic phenotype following completion of clinical studies 206713 or 213744.

This study is a multi-center, randomized, double-blind, placebo-controlled Phase II clinical study to evaluate the efficacy, safety, PK characteristics, PD effects and immunogenicity of CM310 in subjects with moderate to severe asthma. The study consists of three periods, including an up to 4-week screening period, a 24-week randomized treatment period, and a 8-week safety follow-up period.

This is a randomized placebo-controlled trial of semaglutide, an FDA-approved therapy for the treatment of type 2 diabetes mellitus and obesity, in adults with symptomatic asthma despite the use of inhaled steroids and with excess body weight. This study will test the central hypothesis that semaglutide will improve asthma control and reduce airway inflammation due to direct effects on the respiratory tract in adult asthma associated with obesity.

To compare the effects of aerobic training and behavioural intervention to increase physical activity in the clinical control of asthma and in the quality of life of patients with asthma.

Asthma attacks which are moderate-to-severe are typically treated with corticosteroids, but the optimal treatment duration is unknown and treatment responses can be variable. Inadequate treatment may compromise recovery, but increased exposure to corticosteroids is, in turn, associated with drug-related adverse effects. There is a need for a biomarker to guide duration of corticosteroid treatment in asthma attacks. One such candidate biomarker is the blood eosinophil count, which may predict steroid-responsiveness. We hypothesize that the blood eosinophil count can potentially be used as a biomarker to guide the duration of corticosteroids in moderate-to-severe asthma attacks. This study will recruit individuals hospitalized for asthma attack. Participants will be randomized to standard care or blood-eosinophil guided systemic corticosteroid therapy. Subjects in the standard arm will receive oral corticosteroids for a total of 5 days. Subjects in the blood-eosinophil guided arm will receive oral corticosteroids for a total of 5 days if admission eosinophil count is ≥ 0.300 x 10^3/µL, and receive 3 days of oral corticosteroids if the admission blood eosinophil is < 0.300 x 10^3/µL. The rate of treatment failure will be compared between these two groups.
