The presentations will provide additional mechanistic validation of CBL-B, Aurora kinase A (AURKA) and mutant BRAF as therapeutic targets across multiple cancer indications and will highlight the potential of Nurix’s orally bioavailable degraders to effectively suppress the oncogenic activity of these proteins in preclinical models.

Additionally, Gwenn Hansen, Ph.D., chief scientific officer of Nurix Therapeutics, has been selected to speak in an AACR (Free AACR Whitepaper) Advances session on induced proximity pharmacology, including targeted protein degradation. AACR (Free AACR Whitepaper) Advances sessions bring together leading scientific perspectives to provide a comprehensive view of recent developments, the current state of research, and emerging challenges in the field.

About NX-1607
NX-1607 is an investigational first-in-class oral inhibitor of the E3 ligase Casitas B-lineage lymphoma proto-oncogene B (CBL-B) being developed for immuno-oncology indications, including a range of solid tumor types. CBL-B is a cytoplasmic E3 ubiquitin ligase that negatively regulates T cell activation, making it an attractive target for immuno-oncology and offering a novel therapeutic approach to treat solid tumors. Inhibition of CBL-B in preclinical studies reverses T cell exhaustion, alleviates tumor induced immunosuppression, and may also exert direct antitumor effects. Nurix is evaluating NX-1607 in an ongoing Phase 1 trial in adults in a range of oncology indications. This study includes a thorough investigation of both dose and schedule in the Phase 1a portion. Additional information on the NX-1607 clinical trial can be accessed at www.clinicaltrials.gov (NCT05107674).

About NRX-0305
NRX-0305 is a potent, selective, and orally bioavailable CNS-penetrant pan-mutant BRAF degrader that Nurix is exploring for use in oncology. Nurix has reported preclinical data demonstrating potent anti-tumor activity in multiple cell line-derived and patient-derived xenograft disease models representing Class I, Class II, and Class III B-RAF mutations. Anti-tumor activity was also observed in the setting of CNS disease and treatment-resistance, suggesting the potential for utility across a broad range of solid tumor types.

About NRX-4972
NRX-4972 is a CNS-penetrant, orally bioavailable and highly selective degrader of Aurora A kinase (AURKA). AURKA is an oncogene frequently overexpressed in adult solid tumors, hematologic malignancies, and pediatric cancers. Several AURKA inhibitors are effective in preclinical tumor models, but this activity has failed to translate into clinical efficacy. To address the limitations of inhibitors, Nurix has designed bifunctional targeted protein degraders of AURKA that enable removal of both enzymatic and scaffolding functions.
