Official title
An Observational Study of the Effects of Metreleptin in Young Adults With Congenital Leptin Deficiency
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study has been designed to 1) provide access to metreleptin to the only two individuals in the US known to have congenital leptin deficiency (CLD) and 2) explore a variety of unanswered questions about leptin physiology in general and metreleptin therapy in CLD specifically. The primary study endpoints include the following measures: body composition, measures of hepatic steatosis, measures of insulin sensitivity, and measures of sleep architecture. Secondary study endpoints include assessment of clock gene expression, body temperature, thyroid function, gonadal function, cognitive function, eating behavior, physical activity, mood, quality of life, and body image.
