SAN FRANCISCO, CA, USA I April 17, 2025 I Nurix Therapeutics, Inc. (Nasdaq: NRIX), a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of targeted protein degradation medicines, announced today that the U.S. Food and Drug Administration (FDA) has cleared the IND for the IRAK4 degrader GS-6791/NX-0479, enabling the initiation of a Phase 1 trial, which is anticipated to begin in Q2 2025.
“GS-6791/NX-0479 is a highly optimized, selective, oral degrader of IRAK4, a master regulator of IL-1R/TLR signaling pathways that plays a crucial role in inflammatory processes. IRAK4 has both kinase and scaffolding functions, thus complete pathway blockade requires an innovative approach like targeted protein degradation,” said Gwenn M. Hansen, Ph.D., chief scientific officer of Nurix. “In preclinical studies, GS-6791/NX-0479 has demonstrated rapid and potent IRAK4 degradation across multiple human cell types in vitro, as well as rapid and sustained degradation in non-human primates. The ability to achieve complete IRAK4 degradation and cytokine suppression in disease-relevant tissues such as synovial fibroblasts and keratinocytes supports GS-6791/NX-0479’s potential as a best-in-class therapeutic. Additionally, GS-6791/NX-0479 has shown robust efficacy in rodent models of arthritis, supporting its potential to deliver superior therapeutic benefits for chronic inflammatory diseases including rheumatoid arthritis and atopic dermatitis.”
“Today’s announcement highlights the continuing success and productivity of our collaboration with Gilead and demonstrates Nurix’s ability to advance potential best-in-class degrader-based medicines for patients suffering from inflammation and autoimmune diseases,” said Arthur T. Sands, M.D., Ph.D., president and chief executive officer of Nurix. “GS-6791/NX-0479 is one drug candidate emerging from Nurix’s growing pipeline of degrader-based medicines designed to treat inflammation and autoimmune diseases, including our STAT6 degrader in collaboration with Sanofi and our proprietary BTK degrader NX-5948, which we plan to evaluate in patients with inflammation and autoimmune diseases.”
In June 2019, Gilead and Nurix entered into a global strategic collaboration to discover, develop and commercialize a pipeline of up to five innovative targeted protein degradation therapies for patients with cancer and other challenging diseases. Under the terms of the agreement, Nurix received an upfront payment of $45 million and was eligible to receive success-based preclinical milestones totaling $15 million, along with a licensing fee of $20 million and $425 million in potential clinical, regulatory, and commercial milestones payments per program as well as up to low double-digit tiered royalties on net sales. Following the receipt of $5 million for the IND clearance, Nurix remains eligible for $420 million in potential future milestones for the IRAK4 program. Nurix retains the option to co-develop and co-detail up to two programs in the United States, following completion of an applicable Phase 1 clinical trial, subject to certain restrictions. For those programs that Nurix opts in to co-develop and co-detail, the parties will split development costs as well as profits and losses 50/50 for the United States, and Nurix will be eligible to receive royalties on ex-U.S. sales and reduced milestone payments. Gilead has the right to veto up to one co-development option, in which case the option will revert back to Nurix for use on potential future licensed products.
About GS-6791/NX-0479
GS-6791/NX-0479 is a potent, selective, oral IRAK4 degrader. IRAK4 plays a critical role in toll-like receptor (TLR) and interleukin-1 family receptor (IL-1R) signaling and has both scaffold and kinase functions, making it an ideal target for disruption by targeted protein degradation. Degradation of IRAK4 by GS-6791/NX-0479 has potential applications in the treatment of rheumatoid arthritis and other inflammatory diseases. Nurix’s collaboration partner, Gilead Sciences, licensed the program in 2023 and is responsible for advancing this program through clinical development.
About Nurix Therapeutics, Inc.
Nurix Therapeutics is a clinical stage biopharmaceutical company focused on the discovery, development and commercialization of targeted protein degradation medicines, the next frontier in innovative drug design aimed at improving treatment options for patients with cancer and inflammatory diseases. Nurix’s wholly owned, clinical stage pipeline includes degraders of Bruton’s tyrosine kinase (BTK), a B-cell signaling protein, and inhibitors of Casitas B-lineage lymphoma proto-oncogene B (CBL-B), an E3 ligase that regulates activation of multiple immune cell types including T cells and NK cells. Nurix also is advancing multiple potentially first-in-class or best-in-class degraders and degrader antibody conjugates (DACs) in its preclinical pipeline. Nurix’s partnered drug discovery pipeline consists of preclinical stage degraders of IRAK4 and STAT6, as well as multiple additional programs under collaboration agreements with Gilead Sciences, Inc., Sanofi S.A. and Pfizer Inc., within which Nurix retains certain options for co-development, co-commercialization and profit sharing in the United States for multiple drug candidates. Powered by a fully AI-integrated discovery engine capable of tackling any protein class, and coupled with unparalleled ligase expertise, Nurix’s dedicated team has built a formidable advantage in translating the science of targeted protein degradation into clinical advancements. Nurix aims to establish degrader-based treatments at the forefront of patient care, writing medicine’s next chapter with a new script to outmatch disease. Nurix is headquartered in San Francisco, California. For additional information visit http://www.nurixtx.com.
