a study to assess the impact of omalizumab on exercise capacity, physical activity, and sleep quality in participants with moderate to severe allergic asthma

Conditions: Moderate-to-severe Allergic Asthma

Summary: this study will assess the effect of omalizumab on exercise capacity, physical activity, and sleep quality after 24 weeks of treatment in participants with moderate to severe allergic asthma. exercise capacity will be assessed using cardiopulmonary exercise testing (cpet). physical activity and sleep quality will be assessed with a wearable physical activity and sleep monitor. the study will consist of a 4-week screening period, a 24-week treatment period, and a 4-week safety follow-up. approximately 60 participants will be enrolled, and omalizumab will be dosed according to the approved united states package insert (uspi) dosing table.
