ARVN Arvinas Inc

Arvinas, Inc. (Nasdaq: ARVN) today announced that three posters for vepdegestrant, including clinical data, will be presented at the 2024 San Antonio Breast Cancer Symposium (SABCS), being held December 10-13, 2024, in San Antonio, Texas. Vepdegestrant is a novel investigational PROTAC estrogen receptor (ER) degrader that is being jointly developed by Arvinas and Pfizer for the treatment of patients with early and locally advanced or metastatic estrogen receptor positive/human epidermal growth factor receptor 2 (HER2) negative (ER+/HER2-) breast cancer.

Poster session details are as follows:

Poster Title: Evaluation of the Combination of Vepdegestrant, a PROTAC Estrogen Receptor (ER) Degrader, Plus Palbociclib in CDK4/6 Inhibitor-Resistant WT ER and ER Y537S Mutant Patient Derived Xenograft (PDX) ModelsPoster Session 3 (ID: P3-01-16)Date: Thursday, December 12Time: 12:30 p.m. – 2:00 p.m. CT

Poster Title: Vepdegestrant, a PROteolysis TArgeting Chimera (PROTAC) Estrogen Receptor (ER) Degrader, Plus Abemaciclib in ER-Pos/Human Epidermal Growth Factor Receptor 2 (HER2) Negative Advanced or Metastatic Breast Cancer: TACTIVE-U Prelim Phase 1b ResultsPoster Session 4 (ID: P4-12-03)Date: Thursday, December 12Time: 5:30 p.m. – 7:00 p.m. CT

Poster Title: Evaluating CYP3A4-Mediated Drug Interaction Risks for Vepdegestrant, a PROteolysis TArgeting Chimera (PROTAC) Estrogen Receptor (ER) Degrader, in Combination with Cyclin Dependent Kinase (CDK)4/6 Inhibitors and EverolimusPoster Session 4 (ID: P4-08-13)Date: Thursday, December 12Time: 5:30 p.m. – 7:00 p.m. CT

About VepdegestrantVepdegestrant is an investigational, orally bioavailable PROTAC protein degrader designed to specifically target and degrade the estrogen receptor (ER) for the treatment of patients with ER positive (ER+)/human epidermal growth factor receptor 2 (HER2) negative (ER+/HER2-) breast cancer. Vepdegestrant is being developed as a potential monotherapy and as part of combination therapy across multiple treatment settings for ER+/HER2- metastatic breast cancer.

In July 2021, Arvinas announced a global collaboration with Pfizer for the co-development and co-commercialization of vepdegestrant; Arvinas and Pfizer will share worldwide development costs, commercialization expenses, and profits.

The U.S. Food and Drug Administration (FDA) has granted vepdegestrant Fast Track designation as a monotherapy in the treatment of adults with ER+/HER2- locally advanced or metastatic breast cancer previously treated with endocrine-based therapy.
