Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are HIV-1 positive adults aged 18 and older with a BMI of 30 or higher, or a BMI of 27 or higher with related health conditions.

Probably not a fit

Patients who have obesity due to endocrine disorders or those unable to comply with the study protocol may not benefit from this study.

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

What this trial studies

This study evaluates the effectiveness and safety of semaglutide, a GLP-1 analogue, in promoting weight loss among obese individuals living with HIV. Participants will be randomly assigned to receive either semaglutide alongside lifestyle interventions or lifestyle interventions alone. The study aims to assess not only weight loss but also the impact of semaglutide on immune function, glucose and lipid metabolism, and gut microbiome in this population. The trial will include adults over 18 years old who are stable on antiretroviral therapy and meet specific BMI criteria.

Why it matters

Potential benefit: If successful, this treatment could significantly improve weight management and overall health for individuals living with HIV who are struggling with obesity.

How similar studies have gone: While the use of semaglutide for weight loss is established, its specific application in obese individuals with HIV is novel and has not been extensively tested.
