This is a study to test a drug called **Atuliflapon** for adults with moderate-to-severe asthma, which is not well controlled. Asthma is a disease that makes it hard to breathe because of swelling in the airways. Atuliflapon is given once a day for 12 weeks. Some people will get a placebo, a "fake" drug with no active ingredients, to compare results. The study is double-blind, meaning neither the participants nor the researchers know who gets the real drug. Participants must be on certain asthma medications before starting and meet specific health criteria. The study involves several visits and tests, including lung function tests and asthma control questionnaires.
- Duration: 12-week treatment period.
- Visits: Multiple visits required for testing and monitoring.
- Compensation: Not specified, but participants can inquire further.
