In addition, when or if used in this presentation, the words “may,” “could,” “should,” “anticipate,” “believe,” “estimate,” “expect,” “intend,” “plan,” “predict” and similar expressions and their variants, as they relate to the Company may identify forward-looking statements. Although we believe the expectations reflected in such forward-looking statements are reasonable, we can give no assurance that such expectations will prove to be correct. Readers are cautioned that actual results, levels of activity, performance or events and circumstances could differ materially from those expressed or implied in our forward-looking statements due to a variety of factors, including risks and uncertainties related to our ability to advance our product candidates; obtain regulatory approval of and ultimately commercialize our product candidates; the timing and results of preclinical and clinical trials; our ability to fund development activities and achieve development goals; the impact of the COVID-19 pandemic on our business; our ability to protect intellectual property; and other risks and uncertainties described under the heading “Risk Factors” in our final prospectus pursuant to Rule 424(b)(4) filed with the Securities and Exchange Commission (the “SEC”) on July 24, 2020 and in our Quarterly Report on Form 10-Q for the quarter ended August 31, 2020, as well as other SEC filings.

NX-2127, a Degrader of BTK and IMiD Neosubstrates, for the Treatment of B-Cell Malignancies Presenter: Daniel Robbins, Ph. D. drobbins@nurixtx.com Exhibit 99.1

Slide 3

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

Slide 5

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

Slide 7

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

Slide 8

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.
