Two-year extension of ongoing research collaboration intended to generate multiple additional clinical candidates

Nurix will receive a $15.0 million extension fee, and will remain eligible for up to an additional $73.5 million in potential preclinical research milestones and licensing fees, and up to $1.7 billion in potential future development, regulatory, and sales milestones as well as royalties on future products

Nurix continues to retain co-development and 50/50 profit sharing options on up to two programs in the United States

SAN FRANCISCO, CA, USA I April 02, 2024 I Nurix Therapeutics, Inc. (Nasdaq: NRIX), a clinical stage biopharmaceutical company developing targeted protein modulation drugs designed to treat patients with cancer and inflammatory diseases, today announced that Gilead Sciences has elected to extend the research term of the companies’ ongoing collaboration, originally established in 2019, by an additional two years.

“Gilead’s extension of the research period of this agreement is a testament to the productivity of our collaboration to date. Most importantly, it increases the opportunity for additional clinical candidates and associated milestones to emerge from our work together with the Gilead team,” said Gwenn M. Hansen, Ph.D., chief scientific officer of Nurix. “Progress in the collaboration has already yielded the first development candidate GS-6791 (NX-0479), a potent, selective, oral IRAK4 degrader that has potential applications in the treatment of rheumatoid arthritis and other inflammatory diseases, which Gilead licensed in March 2023. With this extended research term, we aim to deliver multiple additional clinical candidates to advance a portfolio of novel targeted protein degrader therapies with Gilead.”

Under the collaboration agreement, Nurix is deploying its proprietary drug discovery platform to identify novel agents that use E3 ligases to induce degradation of specified drug targets. Gilead has an option to license drug candidates resulting from the work, and Nurix retains co-development and co-detail options on up to two programs in the United States, 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. Upon signing the agreement in 2019, Gilead made an upfront payment of $45.0 million. Through Nurix’s fiscal year-end of November 30, 2023, Nurix has received an additional $70.0 million including research milestones, the IRAK4 degrader license option exercise payment and additional payments. In connection with today’s announcement, Nurix will receive a $15.0 million extension fee and remains eligible for up to $73.5 million in preclinical milestones and potential future licensing payments and up to a total of $1.7 billion in potential future development, regulatory, and sales milestones as well as royalties on future products.

About Nurix Therapeutics, Inc.

Nurix Therapeutics is a clinical stage biopharmaceutical company focused on the discovery, development and commercialization of innovative small molecules and antibody therapies based on the modulation of cellular protein levels as a novel treatment approach for cancer, inflammatory conditions, and other challenging diseases. Leveraging extensive expertise in E3 ligases together with 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, clinical stage 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 activation of multiple immune cell types including T cell and NK cells. Nurix is headquartered in San Francisco, California. For additional information visit http://www.nurixtx.com.
