Frequently asked questions about Mibavademab

What is Mibavademab used for?

Mibavademab is an investigational antibody being developed for monogenic obesity, functional hypothalamic amenorrhea (FHA), and generalized lipodystrophy. It is being studied in pediatric and adult patients across these endocrine conditions.

Who is developing Mibavademab?

Mibavademab is being developed by Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN). The company is conducting clinical trials of the drug in the United States, Germany, Brazil, and France.

What phase is Mibavademab in?

Mibavademab is in Phase 2 clinical development. It is an investigational drug and has not been approved by the FDA. Ongoing trials include a Phase 2 study in functional hypothalamic amenorrhea and Phase 3 studies in generalized lipodystrophy and monogenic obesity.

What clinical trials is Mibavademab in?

Mibavademab is being evaluated in several trials. NCT07235917 is a Phase 2 study in adult women with functional hypothalamic amenorrhea. NCT07220772 studies the drug in monogenic obesity due to leptin gene mutations. NCT07220785 and NCT06548100 evaluate it in generalized lipodystrophy.

Is Mibavademab the same as metreleptin?

Mibavademab is not the same as metreleptin. One clinical trial, NCT06548100, studies participants switching from metreleptin to mibavademab for generalized lipodystrophy, indicating they are distinct treatments.

What does Mibavademab target?

Mibavademab is a monoclonal antibody, indicated by its -mab suffix. Its specific molecular target has not been disclosed in available clinical trial information.
