CDXS Codexis Inc

Codexis, Inc. (NASDAQ: CDXS), a leading enzyme engineering company, today announced it has entered into a non-exclusive commercial and manufacturing license agreement with Alphazyme LLC, part of Maravai LifeSciences, for multiple enzymes in Codexis’ life science enzyme portfolio. The agreement includes licenses for the HiFi DNA Polymerase, HiTemp Reverse Transcriptase, HiRev Isothermal Polymerase and other enzymes that were in development directed towards genomics and diagnostics applications prior to the Company’s strategic shift announced in July 2023. Under the terms of the agreement, Codexis is eligible to receive sales-based royalties.

“As our manufacturing partner for the past three years—and with an existing genomics enzyme portfolio and sales force —Alphazyme is the natural choice to extend our commercial reach into this segment. We anticipate a smooth transition for our customers as there is no change in manufacturing supply and many of our customers are already familiar with the Alphazyme team,” said Kevin Norrett, MBA, Chief Operating Officer at Codexis. “This transaction enables Codexis to maintain its focus on maximizing our near-term commercial opportunities and strategic priorities. This includes the growth of our Pharmaceutical Manufacturing business, increasing commercial adoption of the dsRNA ligase, and the build-out of our ECO Synthesis™ Innovation Lab to support manufacturing process development for our customers’ preclinical siRNA assets. We remain on track to achieve key milestones for the ECO Synthesis™ platform this fiscal year, while delivering double-digit product revenue growth and maintaining a path to positive cash flow around the end of 2026.”

Alphazyme is a premier partner for industrial-scale molecular biology enzymes. Alphazyme enthusiastically collaborates with manufacturers of nucleic acid synthesis and detection platforms to produce affordable, custom enzyme formulations of the highest quality that meet the specifications of the rapidly expanding markets for custom DNA and RNA molecules, genomic medicines and genetic testing. “The Codexis and Alphazyme relationship has been strong for many years. We are excited to take on Codexis’ portfolio of high-performing life science and diagnostic enzymes and be a part of their continued success,” said Chad Decker, Vice President and General Manager of Alphazyme. This new collaboration will leverage the experience and industry knowledge of the Alphazyme team to enhance the commercialization of Codexis’ portfolio of life science and diagnostic enzymes.

This license agreement marks another transaction in which Codexis is executing on its strategy to divest the Company’s non-core assets following its strategic shift to focus on the growth of its Pharmaceutical Manufacturing business and Enzyme Catalyzed Oligonucleotide (ECO) Synthesis™ manufacturing platform.

About the ECO Synthesis™ Manufacturing PlatformCodexis’ proprietary Enzyme Catalyzed Oligonucleotide (ECO) Synthesis™ manufacturing platform is being designed to address scalability and cost limitations of traditional phosphoramidite chemistry by potentially enabling the commercial-scale manufacture of RNAi therapeutics through an enzymatic route. The Company presented groundbreaking data at the TIDES USA 2024 annual meeting demonstrating the enzymatic synthesis of a full-length sense strand of the oligonucleotide lumasiran, a commercially available siRNA therapeutic, as well as shorter sense strand fragments of a second siRNA therapeutic asset, givosiran. The data demonstrate that Codexis consistently achieved coupling efficiency greater than 98%, which is equivalent to what is seen with phosphoramidite chemistry; executed the enzymatic addition of a conjugation moiety to the lumasiran strand; and confirmed the lack of notable impurities typically observed in oligonucleotide synthesis via phosphoramidite chemistry. A recording of the presentation, along with slides and the data press release, can be found on the Codexis corporate website.
