Is this trial a fit for you?

Likely a good fit

Ideal candidates are 12-18 year-olds with ASD and obesity (BMI ≥95th percentile) who have Medicaid or can cover semaglutide, with consenting parents and ability to participate for 12 months.

Probably not a fit

Individuals who do not respond to GLP-1 receptor agonists or who have conditions excluding GLP-1 RA use may not benefit.

What this trial studies

This randomized, phase 4 trial enrolls adolescents aged 12-18 with autism spectrum disorder and obesity to receive semaglutide with lifestyle management or lifestyle management alone. The primary outcome is change in body mass index (BMI) from baseline to Month 6. Secondary outcomes include metabolic parameters, safety/tolerability, and adherence to the treatment regimen. The study uses a GLP-1 receptor agonist approach and allows in-person, telehealth, or e-visits over a 12-month participation window to accommodate families.

Why it matters

Potential benefit: If successful, participants may see meaningful reductions in BMI and potential improvements in metabolic health.

How similar studies have gone: Prior GLP-1 RA studies in youth show potential weight loss and metabolic benefits, but data in ASD populations remain limited, making this investigation relatively novel.
