NX-2127 has a dual degradation mechanism of action for two clinically validated targets ©Nurix Therapeutics. All rights reserved. BTK is a tyrosine kinase involved in B cell development, differentiation and signaling BTK inhibitors are approved for treatment of B cell malignancies Mutations to BTK have conferred resistance to approved agents indicating an area of unmet medical need IMiD therapies have shown efficacy in some aggressive B-cell malignancies The dual action of BTK degradation and IMiD activity may provide a unique treatment strategy for relapsed/refractory B-cell malignancies NX-2127 is a novel, hetero-bifunctional, orally administered, Chimeric Targeting Molecule (CTM) that induces the degradation of Bruton’s Tyrosine Kinase (BTK) in cells through recruitment of cereblon (CRBN), a component of the CRL4-CRBN ubiquitin ligase complex The engagement of NX-2127 also catalyzes neosubstrate degradation of Aiolos (IKZF3) and Ikaros (IKZF1), two transcription factors regulating T-cell function Harness (CRBN binder) Hook (BTK binder) Linker NX-2127 Ubiquitin BTK CRBN Catalytic ubiquitination Proteasome BTK A B CRBN BTK Degradation Ikaros Aiolos Catalytic ubiquitination Degradation Proteasome CRBN ubiquitin ligase complex CRBN ubiquitin ligase complex

NX-2127 catalyzes BTK degradation and anti-proliferative activity in cancer cell lines ©Nurix Therapeutics. All rights reserved. NX-2127 catalyzes potent degradation of BTK in DLBCL cell lines (TMD8), including cells with the ibrutinib-resistance mutation BTKC481S NX-2127 catalyzes BTK degradation in Rec-1 and Mino mantle cell lymphoma cell lines NX-2127 potently blocks cell proliferation of BTKC481S TMD8 cells relative to ibrutinib DC50 = half maximal degradation concentration HTRF = Homogeneous Time Resolved Fluorescence A B C

NX-2127 has minimal in vitro effects on platelet aggregation ©Nurix Therapeutics. All rights reserved. NX-2127 does not show significant inhibition of platelet aggregation in an in vitro platelet aggregation assay


Slide 6

NX-2127 catalyzes Aiolos degradation and IL-2 production similar to IMiD drugs ©Nurix Therapeutics. All rights reserved. IMiD Activity: T Cell Activation and IL-2 Secretion IMiD Activity: Aiolos Degradation in Naïve Human T Cells NX-2127 degrades Aiolos with similar potency to that of pomalidomide and lenalidomide NX-2127 exhibits IMiD-like activity by activation and IL-2 production following CD3/CD28 stimulation

Oral Administration of NX-2127 Demonstrates Cancer Growth Inhibition in Mouse Xenograft Tumor Model ©Nurix Therapeutics. All rights reserved. Tumor Growth Inhibition in Xenograft Model of Wild Type Lymphoma Tumor Growth Inhibition in Xenograft Model of Mutant Ibrutinib-Resistant Lymphoma NX-2127 demonstrates comparable tumor growth inhibition to ibrutinib in a xenograft mouse model containing tumors with a wild type BTK NX-2127 shows more potent tumor growth inhibition compared to ibrutinib in a xenograft mouse model containing tumors with the most common human resistance mutation (C481S) in BTK target protein

Oral Dosing of NX-2127 Degrades BTK in Cynomolgus Monkey ©Nurix Therapeutics. All rights reserved. BTK Levels in B cells at Day 19 BTK Levels in B cells at Day 1 NX-2127 induces significant degradation of BTK in 4 hours and more than 90% degradation through 24 hours post dose Once daily, oral dosing of NX-2127 maintains suppression of BTK protein levels throughout the 19-day duration of the study (NX-2127 PK t1/2 = 5.4 h) QD QD QD


Slide 9

Summary and Conclusions NX-2127 catalyzes potent BTK degradation in vitro and results in anti-proliferative effects in human lymphoma cell lines The IMiD activity of NX-2127 is similar to that of IMiD drugs pomalidomide and lenalidomide and results in T-cell activation NX-2127 demonstrates potent BTK degradation in vivo upon oral dosing in cynomolgus monkey and displays anti-tumor effects in both wild-type and C481S mutant mouse xenograft tumor models NX-2127 combines BTK degradation with IMiD activity to provide an attractive therapeutic strategy in the setting of resistance mutations and an expanded set of B-cell malignancies ©Nurix Therapeutics.
