C4 Therapeutics expands target-first DEL capabilities for molecular glue discovery

C4 Therapeutics described a DNA-encoded library that incorporates its cereblon-binding ligand collection for target-first molecular glue discovery. The company reported known and novel VAV1 degrader hits as platform validation, while stating that it would not advance VAV1 without a partner. This is a discovery-platform update, not the clinical entry of a new drug candidate.

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.
