What this trial studies

This study investigates the effects of metreleptin, a synthetic form of the hormone leptin, on patients diagnosed with anorexia nervosa. It employs a double-blind, placebo-controlled design, where 50 inpatients will receive either metreleptin or a placebo for 14 days. The primary goals are to assess improvements in mood and weight, while secondary objectives include evaluating brain connectivity and various health parameters. The study aims to provide a potential pharmacological treatment for a condition that currently lacks effective medications.

Who should consider this trial

Good fit: Ideal candidates are individuals aged 17 to 65 with a current diagnosis of anorexia nervosa and specific BMI requirements.

Not a fit: Patients with severe psychiatric or somatic comorbidities or those currently using illicit drugs or alcohol may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve mood and weight in patients suffering from anorexia nervosa.

How similar studies have performed: Previous studies have shown positive effects of metreleptin in small cohorts, indicating potential for success in this approach.
