This clinical trial is focused on studying the effects of a medication called glycopyrronium bromide in children aged 6 to less than 12 years who have asthma. Asthma is a condition that affects the airways in the lungs, making it difficult to breathe. The study aims to evaluate how well this medication works, how it moves through the body, and its safety and tolerability in children. The medication is administered as an inhalation powder using a device called a Breezhaler, which helps deliver the medicine directly to the lungs.
Participants in the study will receive different treatments over several weeks. These treatments include the active medication glycopyrronium bromide, as well as other medications like fluticasone propionate, salbutamol, and salmeterol xinafoate, which are also used to manage asthma symptoms. A placebo, which looks like the active medication but does not contain any active ingredients, will also be used for comparison. The study is designed to be double-blind, meaning neither the participants nor the researchers know which treatment is being given at any time, to ensure unbiased results.
The trial will take place over several periods, with each period lasting a few weeks. During these periods, the children will receive different treatments and their lung function will be measured to see how the medication affects their breathing. The study will also monitor any side effects or changes in health that occur during the trial. The goal is to determine the best dose and treatment plan for managing asthma in children, ensuring both effectiveness and safety.
