Nurix Therapeutics, Inc’s Collaboration With Sanofi


Sidley Austin LLP represented Nurix Therapeutics, Inc. on the potentially $2.5 billion strategic collaboration with Sanofi.

Nurix Therapeutics, Inc., a company researching novel therapies that control degradation of disease-causing proteins, today announced a global strategic collaboration with Sanofi to discover, develop and commercialize a pipeline of innovative targeted protein degradation drugs for patients with challenging diseases in multiple therapeutic areas.

Under the multi-year collaboration, Nurix will utilize its proprietary drug discovery platform, DELigase™, that integrates its DNA-encoded libraries (DEL) and its unparalleled portfolio of E3 ligases to create small molecules designed to induce degradation of three specified drug targets, with an option by Sanofi to expand to a total of five targets. Sanofi will have exclusive rights and be responsible for clinical development and commercialization of drug candidates resulting from the work while Nurix will retain the option to co-develop and co-promote up to two products in the United States under certain conditions. The collaboration excludes Nurix’s lead degradation programs for which Nurix retains all rights.

Under the terms of the agreement, Nurix will receive an upfront payment of US$55 million and subsequent payments upon expansion of the number of targets to be included in the collaboration. In addition, Nurix will be eligible to receive up to approximately US$2.5 billion in total payments based on the successful completion of certain research, pre-clinical, clinical, regulatory and sales milestones. For those programs that Nurix exercises its option to co-develop and co-promote, the parties will split U.S. profits and losses evenly and Nurix will be eligible to receive royalties on ex-U.S. net sales on all optioned products.

Nurix Therapeutics develops small molecule inhibitors of ubiquitin ligases to treat a broad range of proliferative and degenerative diseases.
