Oral Estrogen Receptor PROTAC^® Vepdegestrant (ARV-471) is Highly Efficacious as Monotherapy and in Combination with CDK4/6 or PI3K/mTOR Pathway Inhibitors in Preclinical ER+ Breast Cancer Models

Scientists used biochemical and intracellular target engagement assays to demonstrate the mechanism of action of vepdegestrant, and ESR1 wild-type and mutant ER+ preclinical breast cancer models to demonstrate ER degradation-mediated tumor growth inhibition.
