Is this trial a fit for you?

Likely a good fit

Ideal candidates are people aged 12 or older who are offered prescription anti-obesity medications (orlistat, naltrexone/bupropion, liraglutide, semaglutide, or tirzepatide) and do not have diabetes or secondary forms of obesity.

Probably not a fit

People with type 1 or type 2 diabetes or with secondary/syndromic or endocrinopathic forms of obesity are excluded and will not be represented in the results.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a multicenter observational project with a cross-sectional phase that records characteristics of all patients who are offered drug therapy for overweight or obesity and a prospective phase that follows patients who choose to start treatment. Data collected will include medical history, social and behavioral factors, clinical and laboratory measurements, and treatment tolerance. Patients aged 12 years and older who have an indication for approved anti-obesity drugs are eligible, while those with type 1 or type 2 diabetes or secondary forms of obesity are excluded. Those who start medication will be followed regularly for up to five years after treatment start or for 12 months after stopping therapy to monitor effectiveness, safety, and adherence in real-world care.

Why it matters

Potential benefit: If successful, the findings could help clinicians target and personalize support and prescribing to improve outcomes and adherence for people using anti-obesity medications.

How similar studies have gone: Real-world observational studies of GLP-1 receptor agonists and other anti-obesity drugs have demonstrated effectiveness and tolerability, but comprehensive long-term phenotyping of who accepts and adheres to therapy is less common.
