SAN FRANCISCO, July 13, 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 fiscal quarter ended May 31, 2023, and provided a corporate update.

“The expansion of our NX-2127 clinical trial in non-Hodgkin’s lymphomas provides an opportunity to identify clinical benefit in a significant patient population,” said Arthur T. Sands, M.D., Ph.D., president and chief executive officer of Nurix. “In the second half of 2023, we expect to generate clinical data that will provide additional insight into the potential specific applications of both the NX-5948 and NX-2127 BTK degrader programs while we continue to advance our internal and partnered programs.”

Recent Business Highlights

• Nurix announced the initiation of two additional Phase 1b expansion cohorts in the ongoing Phase 1a/1b trial of NX-2127: In June, Nurix announced the initiation of expansion cohorts in patients with diffuse large B cell lymphoma (DLBCL) and mantle cell lymphoma (MCL). The decision to expand was informed by evolving data from the Phase 1a portion of the trial including a rapid and sustained complete response in a patient with DLBCL, as previously reported.
• Nurix enhanced its cash position with the receipt of $20 million from Gilead: In April, Gilead exercised its option to exclusively license Nurix’s oral IRAK4 degrader, which has potential applications in the treatment of rheumatoid arthritis and other inflammatory diseases. GS-6791/NX-0479 is the first development candidate resulting from the 2019 Nurix-Gilead collaboration to discover, develop and commercialize a pipeline of innovative targeted protein degradation therapies. In addition to the $20 million license fee, Nurix could potentially receive up to an additional $425 million in clinical, regulatory and commercial milestone payments, as well as up to low double-digit tiered royalties on product net sales.
• Nurix presented data at the American Association for Cancer Research (AACR) Annual Meeting for its Bruton’s tyrosine kinase (BTK) Targeted Protein Degraders, NX-5948 and NX-2127: In April, Nurix presented preclinical data demonstrating the potent tumor cell-killing activity of Nurix’s BTK degraders, NX-5948 and NX-2127, against a broad range of acquired BTK inhibitor resistance mutations and their superiority compared with other reported BTK degraders. For NX-2127, the structure was disclosed to the broader oncology audience following its initial disclosure in an oral presentation at the American Chemical Society Spring 2023 meeting in March.
• Nurix presented additional data for NX-5948 and NX-2127 at the International Conference on Malignant Lymphoma (ICML): In June, Nurix presented early clinical PK/PD data from the Phase 1a trial of NX-5948 demonstrating rapid, robust and sustained BTK degradation and supporting ongoing investigation in B-cell malignancies and continuing dose escalation. Nurix also presented preclinical data demonstrating the potential utility of NX-5948 in addressing the unmet need in patients with central nervous system (CNS) lymphoma. For NX-2127, early clinical data, including a rapid and sustained complete response, informed Nurix’s Phase 1b dose expansion plans in that trial in patients with DLBCL and MCL.

Upcoming Program Highlights*

• NX-2127: Nurix’s lead drug candidate from its protein degradation portfolio, 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 1 clinical trial of NX-2127, which now includes three Phase 1b expansion cohorts in patients with chronic lymphocytic leukemia (CLL), DLBCL and MCL. Nurix anticipates presenting additional clinical results from this ongoing trial in the second half of 2023. Nurix also anticipates defining a regulatory strategy for NX-2127 in the second half of 2023 based on emerging clinical data and feedback from the FDA. Additional information on the clinical trial can be accessed at www.clinicaltrials.gov (NCT04830137).
• NX-5948: Nurix’s second drug candidate from its protein degradation portfolio, NX-5948, is an orally bioavailable degrader of BTK designed without immunomodulatory activity. Nurix is evaluating NX-5948 in a Phase 1 clinical trial in adults with relapsed or refractory B-cell malignancies and expects to present initial clinical data from the Phase 1a portion of the study in the second half of 2023. In addition, Nurix expects to define a dose for Phase 1b cohort expansion. Additional information on the clinical trial can be accessed at www.clinicaltrials.gov (NCT05131022).
• 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 1a dose escalation trial in monotherapy and in a combination cohort utilizing Paclitaxel in adults in a range of oncology indications and expects to present clinical data from the Phase 1a portion of the study and to define a dose for Phase 1b cohort expansion in the second half of 2023. 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 advancement of strategic collaborations with Gilead Sciences and Sanofi: Nurix expects to continue to achieve substantial research collaboration milestones throughout 2023 from its collaborations with Gilead Sciences and Sanofi.

Fiscal Second Quarter 2023 Financial Results

Revenue for the three months ended May 31, 2023, was $30.7 million compared to $11.4 million for the three months ended May 31, 2022. The increase was primarily due to the receipt of $20 million related to the license option exercise payment from Gilead.

Research and development expenses for the three months ended May 31, 2023, were $45.8 million compared to $47.5 million for the three months ended May 31, 2022. The decrease was primarily related to a decrease in research related costs as we concluded certain studies and sponsored research agreements and a decrease in contract manufacturing as we stabilize the supply needed for our clinical trials, offset by an increase in compensation and related personnel costs and in non-cash stock-based compensation expense. There was also an increase in facility and other costs primarily driven by additional investments in information technology and expenses related to our leases of office and laboratory space.

General and administrative expenses for the three months ended May 31, 2023, were $11.7 million compared to $9.7 million for the three months ended May 31, 2022. The increase was primarily related to an increase in compensation related expenses and non-cash stock-based compensation expense and an increase in outside consulting and professional service costs.

Net loss for the three months ended May 31, 2023, was $24.3 million, or ($0.45) per share, compared to a net loss of $45.4 million for the three months ended May 31, 2022, or ($1.01) per share.

Cash, cash equivalents and marketable securities was $308.6 million as of May 31, 2023, compared to $325.6 million as of February 28, 2023.
