Brief Summary:
Rates of obesity in patients with schizophrenia-spectrum disorder (SSD)s have reached epidemic proportions, with established contributing effects of antipsychotic (AP) medications. Among agents approved for chronic weight management, glucagon-like peptide-1 receptor agonists (GLP-1RA) are associated with reductions in cardiovascular mortality, with recent FDA approval for once weekly semaglutide for this indication. This study will investigate whether semaglutide is effective in reducing body weight in overweight or obese individuals with SSDs who are on APs and do not demonstrate adequate weight loss on metformin (the first line treatment for weight loss in SSDs).
Detailed Description:
People with SSDs die early of iatrogenic cardiometabolic disease. Clinically, metformin remains the first line agent to mitigate this risk. In real-world clinical practice, metformin is likely to remain the first line treatment for AP-induced weight gain (given low cost, efficacy, and safety data). However, metformin is only effective in \~20% of patients. Hence, there is a need for interventions for AP-induced weight gain non-responsive to metformin. GLP-1RAs might represent the next rational step as they have a good safety profile, advantages of weekly administration, and early efficacy evidence to support their use in SSD and comorbid obesity, with benefits on dysglycemia, and visceral adiposity. Semaglutide, recently approved for chronic weight loss is an attractive option given a similar adverse effect profile but superior metabolic efficacy compared to other GLP-1 agents. The observations supporting an association between metabolic perturbations and cognition, along with preliminary evidence for neuroprotective effects of GLP-1RAs, suggest that by modifying metabolic risk factors, the investigators may be able to target difficult-to-treat domains of the illness such as cognitive dysfunction.
This study will examine the effect of semaglutide on:
1. Percentage change in body weight
2. Measures of glucose metabolism and cardiovascular risk factors
3. Psychopathology
4. Cognition
5. Lifestyle-based assessments
