SAN FRANCISCO, April 10, 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 first quarter ended February 29, 2024, and provided a corporate update.

“Nurix had a strong start to 2024 with the recent announcements of the extensions of our collaborations with both Gilead and Sanofi further validating the power of our platform and the expansion of our work in inflammatory diseases with Sanofi, including the STAT6 program, one of the most exciting targets in inflammation,” said Arthur T. Sands, M.D., Ph.D., president and chief executive officer of Nurix. “We look forward to the continued advancement of our exciting clinical pipeline led by NX-5948 in addition to our other wholly owned and partnered programs.”

Recent Business Highlights

• Gilead Sciences elected to extend the research term of the companies’ ongoing collaboration, originally established in 2019, by an additional two years resulting in a $15 million extension fee to Nurix. Gilead has an option to license drug candidates resulting from the work, and Nurix retains co-development and co-detail options on up to two programs in the United States, subject to certain restrictions. For those programs that Nurix opts in to co-develop and co-detail, the parties will split development costs as well as profits and losses 50/50 for the United States, and Nurix will be eligible to receive royalties on ex-U.S. sales and reduced milestone payments. Under the agreement, Nurix remains eligible for up to $73.5 million in preclinical milestones and potential future licensing payments and up to a total of $1.7 billion in potential future development, regulatory, and sales milestones as well as royalties on future products.
• Nurix and Sanofi extended their ongoing research program for STAT6 (signal transducer and activator of transcription 6). STAT6 is a key drug target in type 2 inflammation. Nurix anticipates nominating a clinical candidate from this advanced preclinical program in the coming twelve months. Nurix retains its option to co-develop and co-promote future products in the United States under programs for which Nurix has exercised its option. For those programs for which Nurix exercises its option to co-develop and co-promote, the parties will split U.S profits and losses evenly and Nurix will be eligible to receive royalties on ex-U.S. sales on all optioned products.
• Nurix presented new clinical data for NX-5948 at the American Association for Cancer Research (AACR) 2024 Annual Meeting. Case-studies were presented for two patients, one with primary central nervous system lymphoma (PCNSL) and one with chronic lymphocytic leukemia (CLL) with central nervous system (CNS) involvement, each demonstrating clinically meaningful responses. The presentation also provided evidence of measurable drug levels in the CNS of multiple patients in the ongoing Phase 1 trial who had CNS tumor involvement.
• Nurix announced that it is part of a diverse research team of international experts selected as awardees in this year’s Cancer Grand Challenges competition. The project entitled “Knocking Out Oncogenic Drivers and Curing Childhood Cancers” (KOODAC) has the goal of developing orally bioavailable targeted protein degraders that have the potential to dramatically improve cure rates for children affected by solid tumors. In this industry/academic discovery partnership through Cancer Grand Challenges, Nurix will be making in-kind contributions to address each of the five onco-fusion proteins, leveraging its DELigase technology with the goal of identifying first-in-class targeted protein degraders to onco-fusion proteins for pediatric cancer.

Upcoming Program Highlights*

• NX-5948: NX-5948 is an investigational, orally bioavailable degrader of Bruton’s tyrosine kinase (BTK). NX-5948 is currently being evaluated in a Phase 1a/b clinical trial in adults with relapsed or refractory B-cell malignancies. In mid-2024, Nurix plans to present additional clinical data with higher dose levels and longer treatment duration. In addition, in 2024, Nurix plans to define doses for Phase 1b cohort expansion in CLL and non-Hodgkin lymphoma (NHL) and complete ongoing preclinical studies that can enable an investigational new drug (IND) application for NX-5948 in autoimmune indications. Additional information on the 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 three Phase 1b expansion cohorts in patients with diffuse large B-cell lymphoma (DLBCL), mantle cell lymphoma (MCL) and CLL. Screening and enrollment of new study participants was paused due to a partial clinical hold placed on the study by the FDA, although patients enrolled in the clinical study who were deriving clinical benefit continued to receive treatment in accordance with the ongoing study protocol. The FDA lifted the partial clinical hold in March 2024, and Nurix plans to reinitiate enrollment with the new chirally controlled drug substance in a standard dose escalation study within the current Phase 1a/1b trial. 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 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).
• NX-0479/GS-6791: GS-6791 (previously NX-0479) 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.
• 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.

Fiscal First Quarter 2024 Financial Results

Revenue for the three months ended February 29, 2024, was $16.6 million compared with $12.7 million for the three months ended February 28, 2023. The increase was primarily due to the recognition of revenue from the collaboration with Pfizer that was entered into in the fourth quarter of fiscal year 2023, and a higher percentage of completion of performance obligations in the current period related to the collaboration with Sanofi. During the three months ended February 29, 2024, Nurix achieved a research milestone under its collaboration with Sanofi totaling $2.0 million.

Research and development expenses for the three months ended February 29, 2024, was $50.0 million compared with $45.8 million for the three months ended February 28, 2023. The increase was primarily due to clinical costs and contract manufacturing costs as Nurix continues to progress its clinical trial programs and ongoing patient enrollment.

General and administrative expenses for the three months ended February 29, 2024, was $11.8 million compared with $9.8 million for the three months ended February 28, 2023. The increase was primarily related to an increase in non-cash stock-based compensation expense and an increase in professional service costs.

Net loss for the three months ended February 29, 2024 was $41.5 million or ($0.76) per share compared with $40.7 million or ($0.75) per share for the three months ended February 28, 2023.

Cash, cash equivalents and marketable securities was $254.3 million as of February 29, 2024, compared to $295.3 million as of November 30, 2023.
