MW · —CLASS · Synthetic version of exendin-4 (Gila monster saliva); GLP-1 receptor agonistCATEGORY · Metabolic

FDA-approved for type 2 diabetes (Byetta twice-daily 2005; Bydureon extended-release 2012). First GLP-1 agonist ever approved.

§ B · Mechanism of action

Exenatide is a synthetic version of exendin-4, a peptide originally isolated from the saliva of Heloderma suspectum (Gila monster) that shares ~53% sequence identity with human GLP-1 but is resistant to DPP-4 degradation. Twice-daily Byetta has a ~2.4-hour half-life; the extended-release Bydureon formulation enables once-weekly dosing.

§ C · Human clinical evidence

Extensive. Multiple registrational trials supported approvals for glycemic control in type 2 diabetes. EXSCEL cardiovascular outcomes trial showed non-inferiority but not superiority versus placebo for MACE.

§ F · Safety signal

Class GLP-1 profile. Notable for injection-site nodules with the extended-release formulation. Boxed warning for thyroid C-cell tumors. Pancreatitis signal.

§ H · Regulatory status
