Phase 4 — The treatment has already been approved. Researchers are tracking how it works in a large number of people over time.
This study is testing four different combination inhaled medications—including ANORO, TRELEGY, TRIMBOW, and TRIXEO—to see which works best for people with chronic lung disease caused by long-term exposure to biomass smoke (like smoke from wood fires or agricultural burning). Researchers want to understand how these medications affect the small airways in the lungs and improve breathing and quality of life over a 3-month period.
Many people in rural areas develop chronic lung disease from years of exposure to biomass smoke, but there is limited research on which inhaled treatments work best for this specific group. This trial aims to find the most effective medication option for people whose lungs have been damaged by this type of pollution.
You will have an initial screening visit to confirm your diagnosis and review your medical history. Then you will stop taking certain long-acting breathing medications for 1–3 weeks (a 'washout' period) before starting the study. Once you begin, you will take one of four inhaled medications daily or twice daily for 3 months, keep a symptom diary, and return for follow-up visits where doctors will test your lung function, measure your breathing, and assess your quality of life. The entire study lasts about 4 months from screening to completion.
