Oral STAT6 degrader advances into clinical development for type 2 inflammatory diseases
Nurix has earned approximately $139 million to date under its collaboration with Sanofi and remains eligible to receive approximately $453 million in future milestones associated with the STAT6 program, as well as potential royalties, and retains a U.S. co-development and co-promotion option
BRISBANE, Calif., Aug. 04, 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 that it has earned a $10 million milestone payment following the initiation by its collaborator, Sanofi, of the Phase 1 first-in-human clinical trial of SAR448272/NX-3911, an oral STAT6 degrader.
STAT6 is a key transcription factor within the interleukin-4 (IL-4) and interleukin-13 (IL-13) signaling pathways that drive type 2 inflammation and play a central role in diseases including atopic dermatitis and asthma. With the receipt of the $10 million development milestone payment from Sanofi, Nurix will have received approximately $139 million under the companies’ 2019 collaboration agreement. Sanofi is solely responsible for the ongoing clinical development of SAR448272.
“Advancing SAR448272 into the clinic marks an important milestone for the STAT6 program and further validates the productivity of our DEL-AI drug discovery platform in generating differentiated degrader medicines for immunology,” said Gwenn M. Hansen, Ph.D., chief scientific officer of Nurix. “We look forward to seeing the program advance through clinical evaluation by our partner Sanofi.”
“Today’s announcement represents another important advancement in our long-standing collaboration with Sanofi and further demonstrates our ability to discover innovative targeted protein degraders for major inflammatory diseases,” said Arthur T. Sands, M.D., Ph.D., president and chief executive officer of Nurix. “The advancement of SAR448272 into Phase 1 builds on the strong momentum across our partnered immunology portfolio and reflects the continued execution of our strategy to create significant value through both our wholly owned and partnered degrader programs.”
About the Nurix/Sanofi Collaboration
Under the 2019 collaboration agreement, Nurix deployed its proprietary DEL-AI drug discovery platform to identify novel agents that utilize E3 ligases to induce the degradation of specified proteins. In 2025, Sanofi exercised its license extension option for two programs targeting transcription factors for the treatment of autoimmune/inflammatory diseases including an undisclosed target and STAT6. For both programs, Nurix retains the option to co-develop and co-promote in the United States following demonstration of clinical proof of concept. Upon execution of the collaboration agreement in December 2019, Sanofi made an upfront payment to Nurix of $55 million and subsequently paid an additional $22 million to expand the scope of the collaboration. In June 2025, Sanofi exercised its exclusive license extension option for an undisclosed target and for the STAT6 program, triggering two $15 million license extension payments. Following the receipt of the $10 million milestone associated with initiation of the Phase 1 study, Nurix will have received a total of approximately $139 million under the Sanofi collaboration. Nurix remains eligible to receive approximately $453 million in future development, regulatory and commercial milestone payments associated with the STAT6 program, in addition to potential royalties on future product sales. Nurix also retains an option to co-develop, co-promote, and share profits and losses for the program equally in the United States.
About Nurix Therapeutics
Nurix Therapeutics is a clinical stage biopharmaceutical company focused on the discovery, development and commercialization of targeted protein degradation medicines, a new frontier in drug discovery aimed at improving treatment options for patients with cancer and autoimmune diseases. Nurix’s clinical stage oncology pipeline includes Bexobrutideg, a degrader of Bruton’s tyrosine kinase (BTK), being co-developed in collaboration with Roche, and NX-1607, an inhibitor of Casitas B-lineage lymphoma proto-oncogene B (CBL-B), an E3 ligase that regulates activation of multiple immune cell types including T cells and NK cells. Nurix’s autoimmune disease pipeline includes bexobrutideg in collaboration with Roche and clinical-stage degraders of IRAK-4 in collaboration with Gilead and STAT6 in collaboration with Sanofi. Nurix is also advancing multiple potentially first-in-class or best-in-class degraders and degrader antibody conjugates (DACs) in its wholly owned preclinical pipeline as well as those under collaboration agreements with Gilead Sciences, Inc., Sanofi S.A. and Pfizer Inc., within which Nurix retains certain options for co-development, co-commercialization and profit sharing in the United States for multiple drug candidates. Powered by an AI-integrated discovery engine capable of tackling virtually any protein class, and coupled with unparalleled ligase expertise, Nurix’s dedicated team has built a formidable advantage in translating the science of targeted protein degradation into clinical advancements. Nurix aims to establish degrader-based treatments at the forefront of patient care, writing medicine’s next chapter with a new script to outmatch disease. Nurix is headquartered in Brisbane, California. For additional information visit http://www.nurixtx.com.
