Summary

The prevalence of severe pediatric obesity is on the rise and youth with this condition are at elevated risk for developing chronic diseases such as cardiovascular disease (CVD) and type 2 diabetes mellitus (T2DM). Topiramate, a medication approved by the Food and Drug Administration (FDA) for the treatment of seizures in adults and children, is associated with weight loss. Although not FDA approved for the treatment of obesity, studies in obese adults have demonstrated weight reduction of approximately 5% with 6-12 months of therapy. However, the weight loss effect of topiramate has never been evaluated among children and adolescents. Therefore, the goal of this pilot study is to evaluate the safety and efficacy of 24 weeks of topiramate therapy with a 4-week run-in of meal replacement therapy in adolescents with severe obesity. The primary hypothesis is that 4 weeks of meal replacement therapy followed by 24 weeks of topiramate will have a larger average percent decline in BMI between baseline and 28 weeks compared to meal replacement therapy followed by placebo.

Conditions

Interventions

DRUG

Topiramate

Topiramate will be initiated at a dose of 25 mg (taken orally once daily in the evening), escalated to 50 mg (taken orally once daily in the evening) after 1 week, and escalated to 75 mg (taken orally 25 mg in the morning and 50 mg in the evening) after 2 weeks. Patients who do not tolerate dose escalation will be reduced to the highest tolerated dose for the remainder of the trial.

OTHER

Placebo

Placebo will be taken orally once daily in the evening for the first two weeks, and orally twice daily (AM and PM) for the remainder of the study.
