• Demonstrated NX-2127 overcomes BTK inhibitor resistance mutations and provides clinical benefit to patients with hematological malignancies
  
• Achieved significant milestones in wholly owned clinical programs and partnered preclinical programs
• Maintained strong financial position with year-end cash and marketable securities totaling $373 million

SAN FRANCISCO, Feb. 09, 2023 (GLOBE NEWSWIRE) -- Nurix Therapeutics, Inc. (Nasdaq: NRIX), a clinical stage biopharmaceutical company developing targeted protein modulation drugs designed to treat patients with hematologic malignancies and solid tumors, today reported financial results for the fourth quarter and fiscal year ended November 30, 2022 and provided a corporate update.

“In 2022, Nurix achieved multiple ‘firsts’ in oncology with our drug candidates, establishing Nurix as the leader in the targeted protein modulation field,” said Arthur T. Sands, M.D., Ph.D., president and chief executive officer of Nurix. “Clinical data from Nurix’s NX-2127 Bruton’s tyrosine kinase degrader program demonstrated the ability to overcome BTK inhibitor resistance mutations including those lacking catalytic function, resulting in the first evidence from a BTK degrader of clinical benefit in CLL patients with no alternative approved therapies. We have also established mechanistic proof of concept with our first-in-class CBL-B inhibitor. In 2023, we look forward to maintaining the momentum we have built as we continue to advance our pipeline for patients with significant unmet medical needs in both hematologic malignancies and solid tumors.”

Recent Business Highlights

Provided updated clinical data from NX-2127 Bruton’s tyrosine kinase (BTK) degrader program at the American Society of Hematology (ASH) Annual Meeting: In December 2022, two oral presentations were given at the ASH meeting by Nurix collaborators Anthony Mato, M.D., MSCE, former director of the Chronic Lymphocytic Leukemia (CLL) Program at Memorial Sloan Kettering Cancer Center, and Omar Abdel-Wahab, M.D., Chair of Sloan Kettering Institute (SKI) Molecular Pharmacology Program at Memorial Sloan Kettering Cancer Center. Specifically, the first presentation described positive data from the ongoing Phase 1 trial of NX-2127 demonstrating clinically meaningful objective responses in a heavily pretreated patient population harboring multiple BTK inhibitor resistance mutations. The second presentation detailed the variety of emerging BTK inhibitor resistance mutations identified in the trial, all of which remain susceptible to BTK degradation. These new scientific findings support the rationale for BTK degradation as a novel mechanism of action to address the current and emerging unmet need in patients whose cancer has relapsed following multiple prior lines of therapy.

Presented clinical data from NX-5948 BTK degrader program and expanded geographical reach of ongoing clinical trial: At an analyst event held by Nurix at the ASH Annual Meeting, Nurix presented initial PK/PD data from the Phase 1 clinical trial of NX-5948 in adults with relapsed or refractory B-cell malignancies demonstrating early evidence of target engagement with rapid and sustained BTK degradation in all patients and no evidence of immunomodulatory-associated adverse events. An archived webcast of the event, which also covered the ASH Annual Meeting presentations of NX-2127 data, can be accessed via the Events and Presentations page of the Investor section of the Nurix website. In addition, in December 2022, Nurix announced that it received clearance from the U.S. Food and Drug Association (FDA) for its investigational new drug (IND) application to expand the drug candidate’s Phase 1a/1b trial, which is ongoing in the United Kingdom, into sites in the United States. The trial is designed to evaluate the safety and tolerability of NX-5948 in adults with relapsed and refractory B-cell malignancies.

Presented multiple posters highlighting data from Nurix’s Casitas B-lineage lymphoma proto-oncogene (CBL-B) inhibitor programs at the Society for Immunotherapy of Cancer (SITC) Annual Meeting: At the SITC Annual Meeting in November 2022, Nurix presented six posters focused on its CBL-B inhibitor programs, including initial biomarker data demonstrating successful target engagement of CBL-B in patients treated in the ongoing Phase 1 clinical trial of NX-1607. The development and implementation of a novel proprietary biomarker indicate that the doses of NX-1607 currently being tested in the study are achieving biologic activity anticipated to be within the therapeutic range based on the results from relevant animal models.

Completed safety run-in portion of the Phase 1 clinical trial of DeTIL-0255: In November 2022, Nurix announced the successful completion of the safety run-in portion of the Phase 1 clinical trial of DeTIL-0255 in patients with advanced gynecologic malignancies. Based on the preliminary safety profile of DeTIL-0255 and feedback from the FDA, Nurix may explore a potential combination of NX-1607 with cell therapy.

Advanced preclinical discovery programs with collaboration partners Gilead Sciences and Sanofi: Nurix is advancing ten discovery programs under its collaboration partnerships with Gilead Sciences and Sanofi. Of its ten partnered programs, Nurix has options to co-develop and co-promote a total of four programs in the United States. Throughout 2022, Nurix made significant progress within its collaborations as evidenced by the receipt of multiple milestone payments from both partners.
