SAN FRANCISCO, April 08, 2025 (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 reported financial results for the fiscal quarter ended February 28, 2025, and provided a corporate update.

“Nurix had a strong first quarter marked by important collaboration and regulatory achievements and key additions to our leadership team and Board,” said Arthur T. Sands, M.D., Ph.D., president and chief executive officer of Nurix. “Nurix remains on track to initiate pivotal trials of bexobrutideg, our oral, brain-penetrant, BTK degrader for the treatment of patients with chronic lymphocytic leukemia in 2025. In addition, Nurix continues to make significant progress with our pipeline of degrader-based drugs for the treatment of autoimmune disease and inflammation. Most recently we announced that Sanofi exercised its option to exclusively license an undisclosed Nurix program targeting a previously undruggable transcription factor that is a central regulator of the inflammation response and is distinct from the previously disclosed STAT6 degrader program.”

Recent Business Highlights

  • Bexobrutideg is the new nonproprietary name for NX-5948: In March 2025, in collaboration with the national naming authority, the United States Adopted Name (USAN) Council, Nurix’s lead Bruton’s tyrosine kinase (BTK) degrader, NX-5948, was assigned the nonproprietary name “bexobrutideg.” The U.S. and international drug naming convention is designed to select a single name of worldwide acceptability for each active substance that is intended to be marketed as a pharmaceutical. Most notable with bexobrutideg is the designation of a new suffix, “deg,” which references bexobrutideg’s novel degradation mode of action. Targeted protein degraders are characterized by their bifunctional nature, binding to both a target protein and a ligase to drive ubiquitination and catalytic degradation of the target through the proteasome. The new deg suffix is an important recognition that the mechanism of action, pharmacokinetics and pharmacodynamics of targeted protein degraders are fundamentally different than inhibitors, which all use the “ib” suffix. The central stem of the name, “bruti,” references the target, Bruton’s tyrosine kinase (as used in ibrutinib, zanubrutinib and acalabrutinib), and the prefix “bexo” is the unique identifier of a specific agent in the class and is often used for ease of reference to the agent.

  • Bexobrutideg received U.S. FDA Orphan Drug designation for Waldenström macroglobulinemia: In March 2025, bexobrutideg was granted U.S. Food and Drug Administration (FDA) Orphan Drug Designation for the treatment of Waldenström macroglobulinemia (WM). The FDA's Orphan Drug Designation program provides orphan status to therapies intended for the treatment, diagnosis, or prevention of rare diseases that affect fewer than 200,000 people in the United States. This designation provides certain benefits, including tax credits for qualified clinical testing, waiver or partial payment of FDA application fees and seven years of market exclusivity, if approved.

  • Announced the appointment of Roy Baynes to Nurix’s board of directors: In March 2025, Nurix announced the appointment of Roy D. Baynes, MB.Bch., M.Med., Ph.D., to its board of directors. Dr. Baynes currently serves as executive vice president and chief medical officer of Eikon Therapeutics and has had a distinguished career in hematology and oncology and over 22 years of clinical leadership experience in pharmaceutical and biotech companies. Dr. Baynes previously served as chief medical officer and head of global clinical development at Merck, where he supervised the entire clinical portfolio at Merck Research Laboratories. Earlier in his career, Dr. Baynes served as Senior Vice President of Oncology, Inflammation and Respiratory Therapeutics at Gilead Sciences, Inc., as Vice President of Global Development and head of the hematology/oncology development team at Amgen, Inc., and as Professor of Medicine at University of Kansas Medical Center and Wayne State University in Detroit, where he held the Charles Martin endowed chair of Cancer Research.

  • Announced the appointment of John Northcott as chief commercial officer: In January 2025, Nurix announced the appointment of John Northcott as chief commercial officer. Mr. Northcott joins the executive team as Nurix prepares to launch its pivotal clinical program for NX-5948 in chronic lymphocytic leukemia (CLL) and potentially other B-cell malignancies. Mr. Northcott has extensive U.S. and global commercial leadership experience including the successful commercialization of the first marketed BTK inhibitor ibrutinib, and in a wide range of other therapeutic areas.
