BackgroundVepdegestrant (ARV-471) is an oral proteolysis-targeting chimeric (PROTAC) estrogen receptor (ER) degrader with activity toward wild-type and mutant ER. The phase 2 expansion (VERITAC) of a phase 1/2 study tested 2 vepdegestrant doses (200 mg once daily and 500 mg once daily) in heavily pretreated patients with ER+/HER2-negative (HER2–) advanced breast cancer.

BackgroundARV-471 is a selective, orally administered PROTAC protein degrader that targets wild-type and mutant ER1. ARV- 471 directly binds an E3 ubiquitin ligase and ER to trigger ubiquitination of ER and its subsequent proteasomal degradation. In contrast, selective estrogen receptor degraders (SERDs) indirectly recruit the ubiquitin-proteasome system, secondary to conformational changes and/or immobilization of ER2.
