Using an intragastric balloon to improve asthma control in obese patients

Intragastric Balloon in Obese Patients With Uncontrolled Asthma: a Multicentre Randomized Controlled Study

Not applicable Interventional University Hospital, Toulouse · NCT05364957

What this trial studies

This project investigates the impact of an intragastric balloon (IGB) on asthma management in obese patients who have uncontrolled asthma. Participants will be randomly assigned to receive either the IGB along with dietary and exercise interventions or just the dietary and exercise interventions alone. The primary outcome will be measured by the change in Asthma Control Questionnaire (ACQ) scores after one year. The study aims to address the complex relationship between obesity and asthma, particularly in patients who do not respond well to standard asthma treatments.

Who should consider this trial

Good fit: Ideal candidates are men and women aged 18 to 65 with uncontrolled asthma and obesity, specifically those with a BMI between 30 and 40.

Not a fit: Patients with chronic obstructive pulmonary disease (COPD) or those who have recently been diagnosed with cancer may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could lead to improved asthma control and overall health for obese patients with uncontrolled asthma.

How similar studies have performed: While the relationship between obesity and asthma is well-documented, the use of an intragastric balloon for asthma control in this specific population is a novel approach.
