Nurix Therapeutics Announces Achievement of $7 Million Milestone Under Strategic Collaboration with Pfizer

BRISBANE, Calif., Sept. 29, 2026 (GLOBE NEWSWIRE) -- Nurix Therapeutics, Inc. (Nasdaq: NRIX), a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of targeted protein degradation medicines, today announced the achievement of a $7 million research milestone under its strategic collaboration with Pfizer for the discovery and development of degrader antibody conjugates (DACs).

Nurix entered into the collaboration with Seagen Inc., now part of Pfizer, in September 2023. Under the terms of the agreement, Nurix received an upfront payment of $60 million and became eligible to receive up to $3.4 billion in potential research, development, regulatory and commercial milestone payments across multiple programs, as well as mid-single-digit to low-double-digit percentage tiered royalties on future product sales. Nurix also retains an option for U.S. profit sharing and co-promotion on up to two products arising from the collaboration. In connection with today’s announcement, Nurix will receive a $7 million milestone payment from Pfizer, which will bring the total amount received under this agreement to $82 million.

About Degrader Antibody Conjugates (DACs)
DACs are an emerging therapeutic modality designed to combine the cell and tissue selectivity of antibodies with the catalytic mechanism of targeted protein degraders. Unlike traditional antibody-drug conjugates (ADCs), which typically deliver cytotoxic payloads to antigen-expressing cells, DACs deliver targeted protein degraders designed to eliminate specific disease-driving proteins. This approach has the potential to provide multiple layers of selectivity based on cell-surface antigen expression, the intracellular protein target and E3 ligase expression.
