Oxytocin for Weight Loss in Adolescents

Status Recruiting

Clinical Trial Summary

This is a randomized, double blind, placebo-controlled study of the effects of intranasal oxytocin in youths with obesity, ages 12-18 years old. Subjects will be randomized to receive intranasal oxytocin or placebo (3 sprays 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.

Clinical Trial Description

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 12-18-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. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
