Efficacy of Dupilumab Added to Medium Dose Inhaled Corticosteroid/Long-acting Beta-agonist (ICS/LABA) in Comparison to ICS Dose Escalation to High Dose ICS/LABA in Adolescent and Adult Patients With Uncontrolled Asthma
NCT06572228
Recruiting
This study is researching a drug called dupilumab. The study is focused on patients who have uncontrolled asthma. Asthma is a condition where the airways narrow and swell, making it difficult to breathe. Uncontrolled asthma means that patients are still having frequent symptoms while taking their current asthma medication. The aim of the study is to see which regimen is more effective: taking dupilumab with an inhaled asthma medication or only taking a higher dose of the inhaled asthma medicati... Read More
