Официальное название

Oxytocin as a Neuroendocrine Therapy for Obesity in Youth

Обзор

This is a randomized, double blind, placebo-controlled study of the effects of intranasal oxytocin in youths with obesity, ages 10-18 years old. Subjects will be randomized to receive intranasal oxytocin or placebo (1 spray per nostril, 4 times per day) for 12 weeks. Study visits include screening to determine eligibility, 2-part main study visits at baseline, week 8, and week 12, and safety check-in visits at weeks 1, and 4; phone calls at weeks 2, 6, and 10, with a safety follow-up visit 6 weeks after the last dose of study drug. Study procedures include appetite, behavioral, metabolic, and endocrine assessments.

Подробное описание

In recent years there has been a dramatic increase in obesity and its complications in both children and adults. Earlier treatment substantially reduces the likelihood of developing complications later in life while concurrently improving quality of life and decreasing mortality. Therefore, it is essential to develop safe and effective therapeutic strategies for weight loss, particularly in adolescents. Oxytocin (OXT), a hypothalamic peptide hormone that regulates energy balance, is a novel neuroendocrine weight-loss therapeutic in adults with obesity because it simultaneously reduces energy intake and increases energy expenditure and is well-tolerated. Data are currently lacking regarding effects of OXT administration in adolescents with obesity.

The current study is a 12-week randomized controlled trial (RCT) of OXT vs. placebo in 10-18-year old adolescents with obesity. We hypothesize that OXT administration will decrease weight as a consequence of decreased caloric intake and increased energy expenditure, both partially mediated by reduced hypothalamic inflammation (such inflammation drives weight gain by increasing food intake and reducing energy expenditure). Further, OXT will improve metabolic risk markers, such as visceral and intrahepatic fat, systemic inflammation, and serum lipids.
