Mazdutide (IBI362 / LY3305677)

Evidence profile: Human Phase 3 evidence

Mazdutide (IBI362 / LY3305677) is a synthetic analogue of oxyntomodulin acting as a dual glucagon-like peptide-1 (GLP-1) and glucagon receptor agonist. Unlike GLP-1-only or GIP/GLP-1 compounds, it engages the glucagon receptor as well, a mechanism examined in the published literature for its distinct contribution to energy balance. Mazdutide is not an approved medicine and remains in clinical development. Supplied strictly as a research compound for laboratory use.
