Overview

UM-ERD-4001 is a preclinical-stage, orally bioavailable proteolysis-targeting chimera (PROTAC) designed to degrade estrogen receptor alpha (ERα). Developed by the University of Michigan in collaboration with Proteovant Therapeutics, UM-ERD-4001 utilizes a cereblon (CRBN) E3 ligase ligand connected via an optimized linker to an estrogen receptor ligand. It achieves sub-nanomolar DC50 values for ER degradation and has demonstrated robust oral bioavailability and in vivo efficacy, effectively reducing both wild-type and mutated ERα proteins and inducing tumor regression in breast cancer models.
