SAN FRANCISCO, July 11, 2024 (GLOBE NEWSWIRE) — Nurix Therapeutics, Inc. (Nasdaq: NRIX), a clinical stage biopharmaceutical company developing targeted protein modulation drugs designed to treat patients with cancer and inflammatory diseases, today reported financial results for the second quarter ended May 31, 2024, and provided a corporate update.

“Our second quarter was one of significant advancements on a number of fronts, led by our positive clinical data for NX-5948 presented at EHA2024 in June and reinforced with the strengthening of our balance sheet to accelerate the development of this program,” said Arthur T. Sands, M.D., Ph.D., president and chief executive officer of Nurix. “The data presented at EHA2024, reaffirm the best-in-class potential of our protein degradation platform to address the limitations of current inhibitors against challenging targets such as Bruton’s tyrosine kinase. We enter the second half of 2024 well positioned to develop our lead clinical program, NX-5948, into pivotal clinical trials in CLL in 2025 and to continue to advance our wholly owned pipeline of clinical assets, preclinical programs and strategic collaboration programs with Gilead, Sanofi and Pfizer.”

Recent Business Highlights

• Presentation of positive clinical data from ongoing Phase1a/b trial of NX-5948, Nurix’s orally bioavailable degrader of Bruton’s tyrosine kinase (BTK): On June 16, 2024, Kim Linton, M.B.Ch.B, MRCP, Ph.D., FRCP, senior lecturer at the University of Manchester, a consultant at The Christie NHS Foundation Trust and an investigator on the clinical trial, presented data from the ongoing Phase 1a/b clinical trial of NX-5948 in adults with relapsed or refractory B-cell malignancies in an oral session at the European Hematology Association Congress (EHA2024). NX-5948 demonstrated an objective response rate (ORR) of 69.2% in heavily pretreated chronic lymphocytic leukemia (CLL) patients, including in patients with Bruton’s tyrosine kinase (BTK) inhibitor resistance mutations and patients with central nervous system (CNS) involvement. Clinical responses were rapid and deepening with longer time on treatment, and NX-5948 was well tolerated with extended treatment durations in many patients. Nurix also highlighted its plans for expansion to Phase 1b in CLL and its goal of initiating pivotal development in 2025. The Company hosted a webcast to discuss the presented data and its plans for development of NX-5948, a recording of which is accessible under the Events and Presentations page in the Investors section of the company’s website here.
• Strengthened balance sheet: On April 16, 2024, Nurix announced the closing of its underwritten public offering of 11,916,667 shares of its common stock at a public offering price of $15.00 per share, which includes 1,750,000 shares issued upon the exercise in full by the underwriters of their option to purchase additional shares of common stock. In addition, and in lieu of common stock, Nurix sold to certain investors pre-funded warrants to purchase 1,500,100 shares of common stock at a purchase price of $14.999 per pre-funded warrant, which represents the per share public offering price for the common stock less the $0.001 per share exercise price for each such pre-funded warrant. The net proceeds from the offering were approximately $188.7 million after deducting underwriting discounts and commissions and other offering expenses.
• Strengthened leadership with C-suite appointments: On May 28, 2024, Nurix announced the appointments of Paula G. O’Connor, M.D., as chief medical officer and Pasit Phiasivongsa, Ph.D., as chief technical officer of Nurix. Dr. O’Connor joined Nurix in September 2022 and most recently served as executive vice president and head of clinical development. Dr. Phiasivongsa joined Nurix in August 2022 and most recently served as executive vice president of technical operations. These appointments strengthen leadership in clinical operations and CMC ahead of planned pivotal studies for NX-5948 in 2025.
• Election of new board chair: Nurix’s board of directors unanimously elected board member Julia P. Gregory as its new board chair, and Judith A. Reinsdorf, J.D., as its new Nominating and Corporate Governance Committee chair, effective as of May 20, 2024. Ms. Gregory joined the Nurix board in 2019 and currently also serves as the chair of its Audit Committee and as a member of its Nominating and Corporate Governance Committee. Ms. Reinsdorf joined the Nurix board in 2021 and currently also serves as a member of its Audit Committee. David L. Lacey, M.D., stepped down as board chair and remains on the Nurix board serving as chair of its Compensation Committee and a member of its Development Advisory Committee.

Upcoming Program Highlights*

NX-5948: NX-5948 is an investigational, orally bioavailable degrader of BTK. NX-5948 is currently being evaluated in a Phase 1a/b clinical trial in adults with relapsed or refractory B-cell malignancies. In the second half of 2024, Nurix plans to present additional clinical data from this study for patients with CLL and non-Hodgkin lymphoma (NHL). In addition, in 2024, Nurix plans to define doses for Phase 1b cohort expansion in CLL to enable pivotal trial initiation in 2025. Nurix also plans to complete preclinical studies to enable an investigational new drug (IND) application for NX-5948 in autoimmune indications. Additional information on the Phase 1a/b clinical trial can be accessed at www.clinicaltrials.gov (NCT05131022).

NX-2127: NX-2127 is an orally bioavailable degrader of BTK with immunomodulatory activity for the treatment of patients with relapsed or refractory B-cell malignancies. Nurix is conducting a Phase 1a/b clinical trial of NX-2127, which includes Phase 1b expansion cohorts focused on patients with diffuse large B-cell lymphoma (DLBCL) and mantle cell lymphoma (MCL). As previously announced, in March 2024, the FDA lifted a manufacturing-related, partial clinical hold on the NX-2127 clinical trial. Nurix plans to reinitiate enrollment with the new chirally controlled drug product in a standard dose escalation study within the current Phase 1a/1b trial in the second half of 2024. Additional information on the clinical trial can be accessed at www.clinicaltrials.gov (NCT04830137).

NX-1607: Nurix’s lead drug candidate from its targeted protein elevation portfolio, NX-1607, is an orally bioavailable inhibitor of the E3 ligase Casitas B-lineage lymphoma proto-oncogene B (CBL-B) for immuno-oncology indications including a range of solid tumor types and lymphoma. Nurix is evaluating NX-1607 in an ongoing, Phase 1 trial in monotherapy and in a combination cohort utilizing paclitaxel in adults in a range of oncology indications. In the second half of 2024, Nurix expects to present data from the Phase 1a dose-escalation portion of the trial of NX-1607 and to define dose(s) to enable Phase 1b cohort expansion. Additional information on the clinical trial can be accessed at www.clinicaltrials.gov (NCT05107674).

GS-6791 (previously NX-0479): GS-6791 is a potent, selective, oral IRAK4 degrader. Degradation of IRAK4 by GS-6791 has potential applications in the treatment of rheumatoid arthritis and other inflammatory diseases. Nurix’s partner, Gilead, is responsible for conducting IND-enabling studies and advancing this program to clinical development.

STAT6 degrader: In April 2024, Nurix announced an extension of the ongoing research program with Sanofi for STAT6 (signal transducer and activator of transcription 6), a key drug target in type 2 inflammation, with the goal of nominating a development candidate in the first year of the extended term. Nurix remains on track for this goal.

Continued pipeline advancement of strategic collaborations with Gilead, Sanofi and Pfizer: Nurix expects to continue to achieve substantial research collaboration milestones throughout the terms of its collaborations with Gilead, Sanofi and Pfizer.
