GLP-1 Impacts on Weight Management (GLOW)

14. september 2026 opdateret af: University of California, San Francisco

GLP-1 Longitudinal Outcomes in Weight Management

The goal of this observational study is to learn about the long-term effects of GLP-1RAs (Ozempic, Wegovy, Rybelsus, Mounjaro, or Zepbound) in adolescents and young adults aged 12-21 who will start taking this drug for weight management. The main question it aims to answer is:

How does starting GLP-1RAs impact eating behaviors and mental health symptoms?

Participants starting to take GLP-1RAs as part of their medical care for weight management will answer online survey questions about their experience taking the drug for 1 year.

Detaljeret beskrivelse

This prospective single-arm observational study will enroll 100 adolescents and young adults 12 to 21 years of age who are initiating a prescribed glucagon-like peptide-1 receptor agonist (GLP-1RA) therapy or related incretin-based therapy for weight management. The study will assess longitudinal changes in eating behaviors and related clinical features from pre-treatment baseline through 6 months of GLP-1RA treatment, spanning treatment initiation, titration, and maintenance. Exploratory cognitive assessments and biomarker collection will examine behavioral and biological correlates of change. After 6 months, participants will be in follow-up and attend a final study visit at their 12-month mark.

Beskrivelse

Inclusion Criteria:

  • Able to understand and provide informed consent or, for minor participants, able to provide assent with parent/guardian informed consent
  • Age 12 and 21 years at the time of consent
  • Able to read and write in English; for minor participants, at least one parent/guardian must be able to read and write in English or Spanish
  • Willing and able to complete all required in-person and remote study visits and procedures
  • Current binge-eating symptomatology
  • Initiating first-time GLP-1RA therapy or related incretin-based therapy for weight management (Ozempic, Rybelsus, Wegovy)
  • Meets current FDA medication eligibility criteria for prescribed GLP-1RA treatment for weight management: BMI ≥95th percentile OR ≥85th percentile with ≥1 weight-related comorbidity for those <18 years old and a BMI>30 or BMI>26 with ≥1 weight-related comorbidity for those 18 years old and older
  • Has reliable access to prescribed GLP1-RA medication through insurance coverage, self-payment, or discount pharmacy plans and is willing to take it as prescribed for the duration of study participation
  • On a stable regimen of permitted concomitant medications for at least 1 month prior to GLP-1RA initiation. Participants recently taking prohibited medications may be eligible after an adequate wash-out period as applicable (minimum of 5 half-lives).
  • Receiving care in a clinic affiliated with the research study

Exclusion Criteria:

  • Current use of Lisdexamfetamine (Vyvanse) or insufficient washout from such medication prior to GLP-1RA initiation
  • Anticipated medication changes or planned surgical procedures during the study period that, in the investigator's judgment, could affect study participation of interpretation of outcomes
  • Known genetic metabolic or endocrine syndromes associated with obesity, including Prader Willi Syndrome and familial hypercholesterolemia
  • Personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2
  • Type 1 or type 2 diabetes
  • History of pancreatitis
  • Documented uncontrolled thyroid disease
  • History of bariatric surgery
  • Current pregnancy or known plans to become pregnant within the next 6 months
  • Suicidality or any suicide attempts within the past 3 months
