• Includes an option for the global development of CDX-6114 for PKU, marking Codexis’ first partnership for an internally developed biotherapeutic product. Codexis receives an upfront payment of $14 million and potential milestones and royalties depending on product success
• In addition, the partnership adds strategic access to the CodeEvolver® platform for the discovery of additional enzyme therapies for other metabolic disorders requiring drug therapy, as well as novel enzymes for use in medical nutrition and consumer care products

REDWOOD CITY, Calif, Oct. 12, 2017 (GLOBE NEWSWIRE) -- Codexis, Inc. (NASDAQ:CDXS), a leading protein engineering company, and Nestlé Health Science announce a strategic collaboration encompassing multiple projects accessing Codexis’ CodeEvolver® protein engineering platform. The collaboration includes an option for the global development of Codexis’ novel, orally delivered, enzyme, CDX-6114, for the management of phenylketonuria (PKU), an orphan metabolic disorder. In addition, Nestlé Health Science has secured strategic access to the CodeEvolver® protein engineering platform for the discovery of biotherapeutics for other metabolic disorders, and for the development of novel enzyme products for Nestlé Health Science’s Medical Nutrition and Consumer Care business areas.Terms of the partnershipUnder the terms of the option agreement, Nestlé Health Science will make an upfront payment of $14 million. Codexis will be eligible to receive clinical development, approval and commercial milestone payments related to CDX-6114 as well as tiered royalties on product sales. Codexis will be responsible for the clinical development costs for CDX-6114 up to and including phase 1 in healthy volunteers. Thereafter, Nestlé Health Science will have an option to obtain an exclusive global license to CDX-6114 and will be responsible for all future development and commercialization. Beyond CDX-6114, Nestlé Health Science secures a right of first negotiation over enzyme therapies for inborn errors of amino acid metabolism, which Codexis has in its pipeline or may discover over the next five years.The partnership also includes a strategic collaboration where Codexis and Nestlé Health Science will leverage the CodeEvolver® platform technology to develop novel enzymes for Nestlé Health Science’s established Consumer Care and Medical Nutrition business areas.“This transaction validates our CodeEvolver® protein engineering platform technology as a biotherapeutic discovery engine, and also highlights our ability to establish customized partnerships for unlocking the power of proteins with a growing list of the world’s great companies,” said John Nicols, Codexis President and Chief Executive Officer. “We look forward to a long term and very productive relationship with the team at Nestlé Health Science.”Greg Behar, Chief Executive Officer of Nestlé Health Science, stated, “Enzymes are key to healthy functioning. When enzymes are not present or not working properly there can be an impairment of a wide range of processes critical for human health. The partnership with Codexis strengthens our footprint in the enzyme field, a fast developing part of the nutritional therapy innovation frontier that is changing the way we manage our health.”About Phenylketonuria (PKU) PKU is an inborn metabolic disorder resulting from a mutation in the gene for the enzyme that converts the essential amino acid phenylalanine, present in almost all dietary protein, into tyrosine. As a result of this deficiency, phenylalanine builds up to levels that are toxic in the brain, causing serious neurological symptoms including intellectual disability, seizures and cognitive and behavioral disabilities. To avoid phenylalanine toxicity and the most severe disease symptoms, individuals with PKU must follow a strict, life-long diet that is low in phenylalanine and supplement their diet with a synthetic phenylalanine-free formula to provide sufficient nutrients. Maintaining a strict, life-long diet is a challenge for individuals with PKU. There are an estimated 50,000 people with PKU in the developed world.About Nestlé Health ScienceNestlé Health Science, a wholly-owned subsidiary of Nestlé, is a health-science company engaged in advancing the role of nutrition therapy to change the course of health for consumers, patients and its partners in healthcare.
