Official title
An Open-Label Study of Mibavademab (REGN4461), a Leptin Receptor Agonist, for the Treatment of Monogenic Obesity Due to Biallelic Loss of Function Variants of the LEP Gene
Overview
This study is researching an experimental drug called mibavademab. The study is focused on patients with a condition called monogenic obesity. Monogenic obesity is caused by a change in the leptin gene that keeps it from working properly. This causes the body to not be able to feel full or control feelings of hunger. The aim of the study is to see how well mibavademab controls the body weight and how safe it is. The study is looking at several other research questions, including: * How much mibavademab is in the blood at different times * Whether the body makes proteins called antibodies against mibavademab (which could stop mibavademab from working as well or could lead to side effects) * What side effects may happen from taking mibavademab

Eligibility criteria
Inclusion criteria
- Has documented medical history of biallelic loss of function variants of the LEP gene prior to the screening visit
- Has class ≥2 obesity at screening and at baseline, as defined in the protocol
Exclusion criteria
- Unwilling or unable to provide, or have the treating physician provide, documented historical weight for at least 6 months prior to screening
- History of bariatric surgery within approximately the past 12 months of study screening
- History of weight loss of ≥5% of body weight in approximately the past 3 months of study screening
- History of genetic causes of obesity other than/in addition to biallelic loss of function variants of the LEP gene
- History of schizophrenia, bipolar disorder, or other mental illness that, in the opinion of the investigator, might pose a safety risk to participation in a clinical study of an investigational drug
