Researchers are investigating two different doses of inhaled Glycopyrronium GP delivered by metered-dose inhaler MDI as add-on treatments to Budesonide and Formoterol Fumarate BFF MDI in children aged 4 to less than 12 years with asthma. This Phase II, multi-center, randomized, double-blind, crossover study aims to assess how these doses affect lung function compared to a placebo MDI added to BFF MDI. The study is designed to better understand the potential benefits and safety of these treatments in this young population with asthma. Participants will undergo a 3-week run-in period followed by three 3-week treatment periods. During the treatment periods, each participant will receive three treatments in different sequences BFF MDI combined with GP MDI Dose A, BFF MDI combined with GP MDI Dose B, and BFF MDI combined with placebo MDI. GP MDI and BFF MDI are both administered twice daily by oral inhalation. The study concludes with a safety follow-up visit 12 to 16 days after the last dose. Throughout the study, lung function will be closely monitored, with the primary outcome being the change from baseline in forced expiratory volume in one second FEV1 at 1-hour post-dose at the end of each 3-week treatment period. Additional measures include morning pre-dose trough FEV1 changes. Participants will attend scheduled visits for assessments, including lung function tests and safety evaluations, ensuring detailed monitoring of treatment effects and participant well-being during the study period.
