Mazdutide

IBI362, LY3305677

Research useEducational entry
Mechanism

An oxyntomodulin-based dual glucagon (GCG) and GLP-1 receptor agonist; GLP-1 activity supports insulin secretion and satiety while glucagon activity may raise energy expenditure and act on hepatic fat metabolism.

Evidence

Supported by phase 3 trials (DREAMS, GLORY) mainly in Chinese adults; approved in China but still investigational elsewhere, with no FDA or EMA authorisation.

Applications
  • Studied for chronic weight management in overweight/obesity
  • Studied for glycaemic control in type 2 diabetes
  • Investigated for hepatic fat/metabolic endpoints
Protocol

Educational overview only — no dosing instructions in the public hub. Where authorised it is a prescription medicine used under medical supervision.

Risks

Most reported effects are gastrointestinal (nausea, diarrhoea, vomiting) typical of incretin drugs; long-term safety outside trial and Chinese-approval settings is not established.

Quality

Approved supply exists only in China via licensed channels; any 'research' vials sold elsewhere are unapproved and carry purity, dosing and safety risk.

Legal status

Approved by China's NMPA (weight management and type 2 diabetes, 2025); investigational and not approved by the FDA or EMA.
