Pfizer PROTAC Licensing Deal With Rigel Adds Royalties To Valuation Story

Pfizer and Arvinas have licensed global development and commercialization rights for VEPPANU, an FDA-approved oral PROTAC for breast cancer, to Rigel Pharmaceuticals. This deal allows Pfizer and Arvinas to receive royalties and milestone payments, shifting VEPPANU from a fully owned commercial effort to a royalty stream for Pfizer. The agreement enables Pfizer to reallocate resources to its broader oncology and PROTAC pipelines, introducing another potential source of future revenue for investors to track.
