Bispecific protein drives dual receptor degradation in mouse eye-disease models

A PNAS study reports RHV, a tetravalent bispecific protein designed to internalize and lysosomally degrade VCAM-1 and VEGFR on pathological vessels. The original abstract describes activity in mouse choroidal neovascularization models, including efficacy comparable to aflibercept at one-quarter of the molar dose. This is preclinical extracellular receptor degradation, distinct from an intracellular small-molecule PROTAC.
