Biology & mechanism

The original. Exenatide is a synthetic version of exendin-4, a peptide isolated from the venom of the Gila monster, which shares roughly 53% sequence identity with human GLP-1 and — crucially — resists DPP-4 cleavage naturally. Its discovery is the reason this entire drug class exists: it demonstrated that a degradation-resistant GLP-1 receptor agonist was pharmacologically viable.

What the research actually shows

First-in-class, approved in 2005. Superseded in potency and convenience by later agents, and now of more historical than clinical interest, but the trial base is long-established.

Regulatory status

FDA-approved for type 2 diabetes. Prescription-only. Some formulations have been discontinued commercially.

Safety signals

Boxed warning on the extended-release formulation for rodent thyroid C-cell tumours. Pancreatitis signal. Renal impairment cautions. Physician supervision required.
