Codexis and Aldevron Enter Exclusive Licensing Agreement for Codex® HiCap RNA Polymerase

Deal creates strategic collaboration to enable more efficient RNA therapeutic development, providing a path to GMP-grade Codexis enzymes

REDWOOD CITY, Calif. and FARGO, N.D., Dec. 13, 2023 (GLOBE NEWSWIRE) -- Codexis, Inc. (NASDAQ: CDXS), a leading enzyme engineering company, today announced it has entered into an agreement with Aldevron, a global leader in the custom development and manufacture of plasmid DNA, RNA and proteins for the biotech industry, whereby Aldevron will acquire a global exclusive license to Codexis’ Codex® HiCap RNA Polymerase. Under the terms of the deal, Aldevron will receive global manufacturing and commercialization rights to the Codex® HiCap RNA Polymerase and Codexis will receive payments for near-term technical milestones, along with commercial milestones and sales-based royalties. Codexis and Aldevron will work together to ensure a smooth changeover for customers during a transitional period.

“We’re excited to partner with Aldevron, a market-leading mRNA manufacturer, to increase our commercial penetration with a path to a GMP-grade version of our Codex® HiCap RNA Polymerase. This should enable the efficient manufacture of more mRNA-based therapeutics, potentially impacting millions of patients,” said Kevin Norrett, MBA, Chief Operating Officer of Codexis. “The execution of this deal demonstrates our ability to create value from game-changing enzymes in our portfolio by getting them into the hands of the right collaborators, and we look forward to building a long-term partnership with Aldevron and the broader Danaher family of companies.”

“Aldevron has long been a provider of research to cGMP proteins, mRNA and pDNA to enable vaccine development, and cell and gene therapy. We are thrilled with the opportunity to exclusively license this differentiating Codex® HiCap RNA Polymerase which demonstrates Aldevron’s commitment to mRNA as a therapeutic modality,” said Tom Foti, GM of Aldevron’s Protein Business Unit. “The T7 RNA Polymerase is the critical enzyme in the manufacturing process, making it a vital asset in support of our mRNA manufacturing service offering. This license is a strategic investment in Aldevron’s continued development our of mRNA ecosystem, ultimately benefiting our clients and the patients they serve.”

About Codex® HiCap RNA Polymerase
Codex® HiCap RNA Polymerase is a uniquely engineered, co-transcriptional capping RNA polymerase that enables researchers to produce synthetic mRNA at the high yield and purity that today’s mRNA-based vaccines and therapeutics demand. It incorporates commercially available cap analogs more efficiently than wild-type T7 (WT T7) RNA polymerase, generates less undesirable double-stranded RNA (dsRNA) byproduct and provides efficient in vitro transcription (IVT).

About Aldevron
Aldevron is a premier manufacturing partner, producing high-quality plasmid DNA, RNA, proteins, enzymes, and other key components for the development of vaccines, gene and cell therapies, immunotherapies, and other treatments. Headquartered in Fargo, North Dakota, and as a part of the Danaher Corporation (NYSE: DHR) family of global science and technology companies, Aldevron supports thousands of scientists who are developing revolutionary, lifesaving treatments for millions of people.
