What side effects are associated with this type of intervention?

Metreleptin, used in the treatment of Multiple Symmetrical Lipomatosis, can have side effects including hypoglycemia, headache, decreased weight, and abdominal pain. Other potential side effects may include fatigue, nausea, and injection site reactions. It is important for patients to discuss these potential side effects with their healthcare provider to manage and mitigate any adverse effects effectively.

What prior FDA approvals exist?

There are no specific FDA-approved treatments for Multiple Symmetrical Lipomatosis (MSL). However, Metreleptin, a recombinant analog of human leptin, is being studied for its effects on body composition and metabolic parameters in MSL patients. Metreleptin is already approved by the FDA for the treatment of generalized lipodystrophy, a condition characterized by abnormal or degenerative conditions of the body's adipose tissue, which shares some metabolic dysfunctions with MSL.

What other types of research exist?

As of 2024, promising novel alternatives to Metreleptin for Multiple Symmetrical Lipomatosis (MSL) patients include GLP-1 receptor agonists (such as semaglutide and liraglutide) due to their effects on weight loss and metabolic regulation. Additionally, therapies targeting adipokines and anti-inflammatory pathways, such as myostatin inhibitors and cardiosphere-derived cells (CDCs), are under investigation and may offer potential benefits. Further clinical trials and studies are needed to confirm their efficacy and safety in MSL patients.

Leptin Analog

Metreleptin for Lipomatosis

Q: What is the mechanism of action of this treatment?

Metreleptin, a recombinant analog of human leptin, plays a crucial role in regulating energy balance and metabolism, which is particularly important for patients with Multiple Symmetrical Lipomatosis (MSL). MSL is characterized by abnormal fat accumulation, and Metreleptin helps by restoring leptin levels, thereby normalizing metabolic functions. This can potentially reduce the size and number of lipomas, offering a targeted approach to manage the disease by addressing the underlying metabolic dysregulation.

Summary

This trial will treat patients with a specific genetic mutation (MFN2 R707W) using Metreleptin. Metreleptin acts like a hormone that helps control hunger and energy use. The study will assess changes in body composition, metabolism, and safety over several months, with additional safety monitoring for an extended period. Metreleptin is an analogue of the human hormone leptin, developed to treat metabolic disorders including lipodystrophy, and has been approved by the FDA for generalized lipodystrophy.

Who is the study for?

This trial is for individuals under 60 with Multiple Symmetric Lipomatosis (MSL), specifically those with a certain genetic mutation (homozygous MFN2 R707W). Participants must be able to undergo blood sampling, not have conditions affecting the study, and if female and of childbearing potential, they must not be pregnant or breastfeeding. They should also be patients at the University of Michigan.

What is being tested?

The trial tests Metreleptin's effects on body composition and metabolic parameters in MSL patients over six months. It aims to evaluate both safety and efficiency by monitoring changes after administering Metreleptin.

What are the potential side effects?

Potential side effects of Metreleptin may include allergic reactions for those sensitive to it, issues related to blood sampling such as bruising or infection, and other unspecified risks that could arise from altering metabolic parameters.
