This study investigates an investigational treatment for individuals with chronic asthma. Chronic asthma is a long-term condition where the airways in the lungs become inflamed and narrowed, making it difficult to breathe. The purpose of this study is to understand the effects of the investigational treatment on managing asthma symptoms.

Participants in the study will be assigned to different study arms. Each arm will receive either the investigational treatment or a placebo. A placebo is an inactive substance that looks like the investigational treatment but does not contain any medicine. The study procedures will involve regular monitoring of asthma symptoms and lung function tests to evaluate the effectiveness of the treatment.

• Who can participate: Adults aged 18 and over with chronic asthma may be eligible to participate. Individuals under 18 are not eligible for this study.
• Study details: Participants will receive either the investigational treatment or a placebo. Participants will undergo regular monitoring of asthma symptoms and lung function tests.
