§1.3Sequence and structural notes

Not applicable — a small molecule, not a peptide

Orforglipron is a non-peptide biased partial agonist that binds the GLP-1 receptor extracellular domain at a site distinct from the native peptide orthosteric pocket. Because it is not a peptide it has no sequence, requires no injection, is not subject to peptide-specific degradation routes, and is analysed by conventional small-molecule chromatography rather than by peptide mapping.

§1.4Assessment status

The Institute assesses Orforglipron across 2 indications and grades the strongest of them at moderate certainty. In confirmatory clinical development; no marketing authorisation.
