About NX-2127
NX-2127 is a novel bifunctional molecule that degrades Bruton’s tyrosine kinase (BTK) and cereblon neosubstrates Ikaros (IKZF1) and Aiolos (IKZF3). NX-2127 is currently being evaluated in a Phase 1a/1b clinical trial in patients with relapsed or refractory B cell malignancies. Initial data from the Phase 1a dose-escalation portion of the study demonstrated clinically meaningful degradation of BTK in all patients, including in a chronic lymphocytic leukemia patient with significant mutations in the BTK gene associated with resistance to standard of care BTK inhibitors. Nurix expects to present additional data from this study in the second half of 2022. Additional information on the clinical trial can be accessed at www.clinicaltrials.gov (NCT04830137).

About DeTIL-0255
DeTIL-0255 is an autologous cell therapy consisting of T cells derived from a patient’s tumor expanded in culture with recombinant interleukin-2 and the small molecule Casitas B-lineage lymphoma proto-oncogene B (CBL-B) inhibitor NX-0255. DeTIL-0255 is designed to be a single administration autologous TIL therapy infused following non-myeloablative chemotherapy. Given the improved phenotypes of T cells produced with CBL-B inhibition, DeTIL-0255 could allow a broader application of TIL therapy, potentially providing long term benefit to patients with multiple types of cancer. Nurix is conducting a Phase 1 trial of DeTIL-0255 in patients with advanced gynecologic tumors at multiple sites in the United States. Additional information on the clinical trial can be accessed at www.clinicaltrials.gov (NCT05107739).

About NX-1607
NX-1607 is an orally bioavailable inhibitor of CBL-B for immuno-oncology indications including a range of solid tumor types. NX-1607 acts on T cells, NK cells, and dendritic cells to enhance anti-tumor immunity, and has demonstrated single-agent anti-tumor activity in multiple tumor models. Nurix is evaluating NX-1607 in an ongoing, Phase 1 dose escalation and expansion trial in adults with a variety of oncology indications at multiple clinical sites in the United Kingdom. Additional information on the clinical trial can be accessed at www.clinicaltrials.gov (NCT05107674).

About Nurix Therapeutics, Inc.
Nurix Therapeutics is a clinical stage biopharmaceutical company focused on the discovery, development, and commercialization of small molecule and cell therapies based on the modulation of cellular protein levels as a novel treatment approach for cancer and other challenging diseases. Leveraging Nurix’s extensive expertise in E3 ligases together with its proprietary DNA-encoded libraries, Nurix has built DELigase, an integrated discovery platform to identify and advance novel drug candidates targeting E3 ligases, a broad class of enzymes that can modulate proteins within the cell. Nurix’s drug discovery approach is to either harness or inhibit the natural function of E3 ligases within the ubiquitin proteasome system to selectively decrease or increase cellular protein levels. Nurix’s wholly owned pipeline includes targeted protein degraders of Bruton’s tyrosine kinase, a B-cell signaling protein, and inhibitors of Casitas B-lineage lymphoma proto-oncogene B, an E3 ligase that regulates T cell activation. Nurix is headquartered in San Francisco, California. For more information, please visit http://www.nurixtx.com.
