Obesity Clinical Trial - Aspiration Therapy in Asian Patients

Status Recruiting

Clinical Trial Summary

This research project will provide insight into the efficacy and safety of aspiration therapy in the management of obesity and its comorbidities in the Asian population, and will determine if there is a role for this novel endoscopic device in the treatment algorithm of obesity in the investigators' local regions.

Clinical Trial Description

Obesity is a major global health problem and Asians are equally affected. According to the latest Behavioural Risk Factor Survey in 2014, 20.8% of adults in Hong Kong have body mass index (BMI) belonging to the obese category. Obesity is associated with a multitude of medical and psychological comorbidities that could cumulate in increased healthcare costs and impaired quality of life. As such, an effective treatment strategy for obesity is imperative.

Sustainable weight reduction by lifestyle measures alone is often difficult if not impossible. Pharmacotherapy can provide additional weight reduction when used as an adjunct to lifestyle intervention but the efficacy is modest. The most effective method for weight reduction to date is bariatric surgery but this is limited by its invasiveness and irreversibility. The limitations of current obesity treatment has led to an increased interest in endoscopic treatment, which may be more effective than pharmacotherapy and less invasive and more reversible than bariatric surgery.

The AspireAssist® Aspiration Therapy System is a novel endoscopic therapy developed by Aspire Bariatrics Inc. (King of Prussia, United States) for treatment of obesity. The system takes advantage of percutaneous endoscopic gastrostomy (PEG) tube technology to induce weight reduction by aspirating a portion of ingested meals from the stomach. In a pilot study involving 18 Caucasian obese subjects randomly assigned in a 2:1 ratio to aspiration therapy group and lifestyle therapy only group, the weight reduction was 18.6% +/- 2.3% and 5.9% +/- 5.0% respectively. The present study aims to investigate the effectiveness and safety of this device in Asian subjects. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
