Impact of Mepolizumab on Physical Activity in Severe Asthma

Evolution of Physical Activity in Severe Asthmatic Patients Treated With Mepolizumab

Observational University Hospital, Lille · NCT05404763

This study is testing if a medication called mepolizumab can help people with severe asthma be more active and improve their ability to exercise over six months.

What this trial studies

This observational study investigates the effects of mepolizumab, a monoclonal antibody targeting interleukin-5, on physical activity and exercise tolerance in patients with severe eosinophilic asthma. It aims to determine whether a 6-month treatment with mepolizumab can improve daily physical activity levels and enhance ventilatory mechanics. The study will include patients aged 18 to 75 who have been diagnosed with severe asthma and have a history of exacerbations and high eosinophil counts. The findings could provide insights into the relationship between asthma management and physical activity.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 75 with severe uncontrolled asthma and a documented history of exacerbations.

Not a fit: Patients with mild asthma or those not meeting the criteria for severe uncontrolled asthma may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved physical activity and quality of life for patients with severe asthma.

How similar studies have performed: While studies have explored the effects of mepolizumab on asthma symptoms, the specific focus on physical activity and exercise tolerance is relatively novel.
