Recent Business Highlights

• Nurix presented positive data from the NX-5948 clinical trial at the American Society of Hematology (ASH) Annual Meeting and the International Workshop on Waldenstrom's Macroglobulinemia: Nurix presented new, positive clinical data from its Phase 1 clinical trial of NX-5948 at the 66th ASH Annual Meeting (ASH2024) in December 2024 and the 12th International Workshop on Waldenstrom's Macroglobulinemia (IWWM-12) in October 2024. NX-5948 is an orally bioavailable, brain penetrant degrader of Bruton's tyrosine kinase (BTK) which is currently being evaluated in adults for the treatment of relapsed or refractory B-cell malignancies, including chronic lymphocytic leukemia or small lymphocytic lymphoma (r/r CLL/SLL) and Waldenstrom's macroglobulinemia (WM). At ASH2024, Nurix reported a robust objective response rate (ORR) of 75.5% among the 49 efficacy-evaluable r/r CLL/SLL patients across all doses tested, with the majority of responses occurring at the first assessment (Week 8). With longer time on treatment, the ORR increased to 84.2% based on an exploratory efficacy analysis of patients who had at least two response assessments (Week 16). Responses and robust BTK degradation were observed across all populations regardless of prior treatment, baseline mutations including those with BTK mutations associated with treatment resistance to both covalent and non-covalent BTK inhibitors, high-risk molecular features, or central nervous system (CNS) involvement. NX-5948 was well-tolerated in all patient populations and across all doses tested from 50 to 600 mg daily. At IWWM-12, in the nine efficacy-evaluable WM patients treated with NX-5948, an ORR of 77.8% was observed with increasing depth of response over time, supporting continued development of NX-5948 for this indication. A webcast of Nurix's ASH2024 presentation and additional discussion on the company's programs and plans is available in the Investors section of the Nurix website.
• NX-5948 received U.S. FDA Fast Track and European Medicines Agency PRIME designations: In 2024, NX-5948 received two separate Fast Track designations from the U.S. Food and Drug Administration (FDA): the first for the treatment of adult patients with r/r CLL/SLL after at least two lines of therapy, including a BTK inhibitor and a B-cell lymphoma 2 (BCL2) inhibitor, and the second for the treatment of adult patients with r/r WM after at least two lines of therapy, including a BTK inhibitor. In Europe, NX-5948 received PRIME designation for the treatment of patients with r/r CLL/SLL after treatment with at least a BTK inhibitor and a BCL2 inhibitor.
• Provided program updates on NX-1607 and NX-2127: In December 2024, Nurix presented a status update on NX-1607, its lead drug candidate from its E3 ligase inhibitor program, stating that drug exposures and proximal biomarker levels at the higher dose ranges from the NX-1607 Phase 1a dose escalation trial are consistent with levels associated with anti-tumor activity in nonclinical models. Preliminary evidence of stable disease, tumor shrinkage and biomarker and clinical responses have been observed in the study. In addition, Nurix presented a status update on NX-2127, its second drug candidate from its BTK degrader portfolio, stating that enrollment in the NX-2127 Phase 1 trial has been re-initiated with new, chirally controlled drug product. Nurix is focusing development of NX-2127 on aggressive lymphomas where the combination of BTK and IKZF1/3 degradation has the potential for synergy and significant therapeutic development.
• Advanced a pipeline of wholly owned and partnered programs in inflammation and immunology: In November 2024, at the annual meeting of the American College of Rheumatology (ACR Convergence 2024), Nurix presented a poster entitled "NX-5948, a Clinical-Stage BTK Degrader, Achieves Deep Suppression of BCR, TLR, and FcR Signaling in Immune Cells and Demonstrates Efficacy in Preclinical Models of Arthritis and Other Inflammatory Diseases.” In December, Nurix announced plans to initiate clinical testing of NX-5948 in autoimmune cytopenias, such as warm autoimmune hemolytic anemia (wAIHA), in 2025, initially as an addition to its ongoing Phase 1b trial in patients with B-cell malignancies. Also, at ACR Convergence 2024, positive preclinical data were presented from Nurix's collaboration with Gilead to develop GS-6791/NX-0479, an IRAK4 degrader, that has potential applications in the treatment of rheumatoid arthritis and other inflammatory diseases. In October, at the 7th Annual TPD & Induced Proximity Summit, Nurix presented preclinical findings for a previously undisclosed, wholly owned, brain penetrant, pan-mutant B-RAF degrader program capable of addressing tumors driven by class 1, class 2 and class 3 mutant forms of B-RAF. In addition, Nurix's ongoing research program with Sanofi was extended for the development of a degrader of 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 half of 2025.
• Announced the appointment of John Northcott as chief commercial officer (CCO): 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 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.

NX-5948: NX-5948 is an investigational, orally bioavailable, brain-penetrant, small molecule degrader of BTK. Nurix currently is conducting a Phase 1b clinical trial of NX-5948 in adults with relapsed or refractory B-cell malignancies. In 2025, Nurix plans to commence a suite of clinical trials designed to support global registration of NX-5948 for the treatment of patients with CLL. In addition, Nurix anticipates moving into autoimmune and inflammatory diseases and expects to open a new Phase 1b cohort for patients with CLL and associated autoimmune hemolytic anemia and is exploring the filing of a non-malignant hematology IND for autoimmune cytopenias in 2025. Future clinical updates in patients with both CLL and non-Hodgkin's lymphoma are anticipated in 2025. Additional information on the NX-5948 clinical trial can be accessed at www.clinicaltrials.gov (NCT05131022).

NX-2127: NX-2127 is an orally bioavailable degrader of BTK and the cereblon neosubstrates IKZF1 (Ikaros) and IKZF3 (Aiolos) for the treatment of relapsed or refractory B-cell malignancies. Nurix currently 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 and mantle cell lymphoma. Following a decision in March 2024 in which the FDA lifted a manufacturing-related, partial clinical hold on the NX-2127 clinical trial, Nurix reinitiated enrollment in a dose escalation study within the current Phase 1a/1b trial using its new chirally controlled drug product. Future clinical updates are anticipated in 2025. Additional information on the NX-2127 clinical trial can be accessed at www.clinicaltrials.gov (NCT04830137).

NX-1607: 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 currently 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. This study includes a thorough investigation of both dose and schedule in Phase 1a. Future clinical updates are anticipated in 2025. Additional information on the NX-1607 clinical trial can be accessed at www.clinicaltrials.gov (NCT05107674).

GS-6791 (previously NX-0479): GS-6791 is a potent, selective, oral degrader of IRAK4. 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, which Nurix anticipates in 2025.

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.

* Expected timing of events throughout this press release is based on calendar year quarters.

Fiscal Fourth Quarter and Year End 2024 Financial Results

Revenue for the three months and twelve months ended November 30, 2024, was $13.3 million and $54.5 million, respectively, compared with $15.2 million and $77.0 million for the three and twelve months ended November 30, 2023, respectively. The decrease for the twelve-month period was primarily due to decreased revenue from the collaboration with Gilead as Nurix received a $20 million license payment for its IRAK4 asset in 2023 and as the initial research term for certain drug targets ended. The decrease was offset by an increase in revenue from the collaboration agreement with Pfizer that was entered into in the fourth quarter of fiscal year 2023. In the fiscal year ended November 30, 2024, Nurix received payment from the achievement of research milestones under its collaborations with Pfizer and Sanofi totaling $5.0 million and $2.0 million, respectively, and received $15 million from Gilead to extend the research term of the companies' ongoing collaboration, originally established in 2019, by an additional two years. In addition, during the three months ended November 30, 2024, Nurix achieved a research milestone under its collaboration with Pfizer, which resulted in the receipt of a $5.0 million payment to Nurix in January 2025.

Research and development expenses for the three months and twelve months ended November 30, 2024, were $67.2 million and $221.6 million, respectively, compared to $49.7 million and $189.1 million for the three and twelve months ended November 30, 2023, respectively. For the twelve-month period, the increase was primarily related to clinical and contract manufacturing costs as Nurix continued to accelerate the enrollment of NX-5948.

General and administrative expenses for the three months and twelve months ended November 30, 2024, were $10.7 million and $45.9 million, respectively, compared to $10.8 million and $42.9 million for the three and twelve months ended November 30, 2023, respectively. The increase for the twelve-month period was primarily related to an increase in non-cash stock-based compensation expense and an increase in professional service and consulting costs.

Net loss for the three months and twelve months ended November 30, 2024, was $58.5 million or ($0.75) per share and $193.6 million or ($2.88) per share, respectively, compared with $42.0 million or ($0.77) per share and $143.9 million or ($2.65) per share for the three and twelve months ended November 30, 2023, respectively.

Cash, cash equivalents and marketable securities was $609.6 million as of November 30, 2024, compared to $295.3 million as of November 30, 2023.
