Official title: Antisense Oligonucleotide-Based Therapeutic Strategy for Genetic Obesity Caused by MC4R Mutations

Funded at Saint Louis University · NIH-11380445 · Data updated 2026-11-12

A new antisense oligonucleotide treatment is being explored to help children with MC4R-related obesity, aiming to reduce excessive hunger and improve weight-related health risks.

Who could benefit from this research

Could help

Children under 10 years old with MC4R-related obesity.

Less likely to help

Children without MC4R-related obesity or those outside the target age range may not benefit.

What this research studies

This grant focuses on a genetic form of obesity caused by MC4R mutations and how a targeted antisense therapy might modulate the pathway that controls appetite. Researchers will examine how to design a safe ASO approach to correct or mitigate the genetic driver in affected individuals. The study emphasizes a translational path from molecular concepts toward a potential pediatric treatment, with attention to safety, dosing, and early efficacy signals. If successful, the work could pave the way for a new option for children under 10 who currently lack approved therapies. The project spans from molecular design to preclinical and early human-relevant studies to inform future trials.

Why it matters

Potential benefit: If successful, the therapy could reduce hunger and obesity-related health risks in children with MC4R mutations.

How similar studies have gone: Other MC4R-focused approaches have progressed, but this A SO strategy in young children is novel and exploratory.
