项目摘要

Abstract Long-term weight loss maintenance is seldom achieved by individuals with obesity owing to numerous biological adaptations occurring in the post-weight loss setting, including neuroendocrine-mediated changes in appetite/satiety and reduction of energy expenditure. Following weight loss, peripheral and central mechanisms respond in a way similar to starvation by conveying a sense that energy reserves have dwindled, activating a strong counter-response to increase caloric intake. Moreover, metabolic rate drops, further compounding the propensity for weight rebound. Adolescents with severe obesity are not immune to the vexing issue of weight regain; therefore, effective and scalable treatments are urgently needed. Pharmacotherapy has the potential to prevent weight regain by targeting counter-regulatory mechanisms in the post-weight loss setting. Unfortunately, only one obesity medication is FDA-approved for long-term use in adolescents and is seldom prescribed owing to modest efficacy and notable side effects. Among the most promising candidates in the pediatric pipeline is the combination of phentermine and topiramate, which is the most effective adult weight loss medication currently available. The mechanisms of action are thought to reduce appetite, enhance satiety, and potentially increase energy expenditure, making this medication particularly well-suited for the purpose of weight loss maintenance since it targets many of the biological adaptations known to induce relapse and subsequent weight regain. Our group has generated preliminary data demonstrating that both phentermine and topiramate reduce BMI in adolescents with severe obesity and have acceptable safety profiles. In this clinical trial, we will utilize phentermine/topiramate to target counter- regulatory pathways responsible for weight regain after meal replacement therapy (structured meals of known caloric content) in adolescents with severe obesity with a goal of enhancing weight loss maintenance and improving co-morbidity outcomes. Importantly, we will maximize the clinical utility and overall impact of our study by comprehensively characterizing the safety of phentermine/topiramate utilizing sensitive measures of cardiac autonomic function, arterial stiffness, cognition, and bone health, as well as examine the extent to which this medication counteracts mechanisms of weight regain.
