Abicipar pegol (AGN-150998, MP0112), an anti-VEGF DARPin molecule, is a novel class of small ankyrin repeat domain-containing proteins designed for high specificity and affinity targeting. This compound effectively inhibits angiogenesis and vascular permeability, and has been applied in ocular inflammation-related disease studies through intravitreal injections, significantly reducing mean retinal thickness and leakage area [1] [2].
