Codexis KOL Event Highlights Significant Need for an Enzymatic Route of Synthesis in RNAi Therapeutics Manufacturing

REDWOOD CITY, Calif., Dec. 11, 2023 (GLOBE NEWSWIRE) -- Codexis, Inc. (NASDAQ: CDXS), a leading enzyme engineering company, hosted a virtual Key Opinion Leader (KOL) event on Friday, December 8, 2023, to discuss the growth of RNA interference (RNAi) therapeutics as a modality, the manufacturing landscape and the potential role for the Company’s Enzyme-Catalyzed Oligonucleotide (ECO) Synthesis™ platform to enable commercial-scale production of RNAi therapeutics. KOL participants included John Maraganore, PhD, Founder and Former Chief Executive Officer of Alnylam Pharmaceuticals, and member of Codexis’ Strategic Advisory Board, and David Butler, PhD, Chief Technology Officer at Hongene Biotech Corporation.

“As part of the pioneering team that established RNAi therapeutics as a whole new class of medicines, I am thrilled to see the field advance with six approved medicines and a large and rapidly growing number of investigational programs in clinical development,” said Dr. Maraganore. “As the RNAi therapeutics field matures, many programs are targeting prevalent disease indications, such as cardiovascular and Alzheimer’s disease. While I am confident in the potential for RNAi therapeutics to transform the treatment paradigms for millions of impacted patients, today’s manufacturing practices rely on traditional chemical synthesis methods that may not accommodate a sharp increase in demand. Accordingly, I have long felt that an enzymatic route of synthesis is a critical innovation to reduce required infrastructure investments, mitigate high volumes of hazardous waste and ensure that drug developers can effectively address the coming demand of these medicines for patients.”

Dr. Butler added, “It’s incredible to see the progress that has been made in advancing siRNA therapeutics, and traditional chemical synthesis has enabled the development and initial commercialization of this modality. However, decades of process improvements are now achieving diminishing returns, and traditional chemical synthesis remains limited by scale per batch, expensive equipment, significant purification and waste disposal costs and a negative environmental impact. A fully enzymatic approach has the potential to improve efficiencies across each of these areas while reducing the significant capital expenditure required of chemical synthesis, all of which would be compelling to the many manufacturers who are ramping up investment in their oligonucleotide production capabilities.”

In addition to the KOL presentations, Codexis management, including Chief Executive Officer Stephen Dilly, MBBS, PhD; Chief Operating Officer Kevin Norrett, MBA; and Senior Vice President of Research Stefan Lutz, PhD, provided a technical overview of the ECO Synthesis™ platform and reviewed the program’s associated commercial opportunity and upcoming milestones.

“We were honored to have Dr. Maraganore and Dr. Butler share their insights on the RNAi manufacturing landscape during last week’s event. Their comments further reinforce the critical need for us to bring our ECO Synthesis™ platform to market, and we are pleased with our recent progress on both the technical and commercial fronts,” said Dr. Dilly. “We are fast approaching our key milestone of achieving gram-scale synthesis by the end of this year, which, if met, will provide additional validation of the potential for an enzymatic route of manufacturing, and also enable us to enter pre-commercial testing with select customers in 2024.”

About the ECO Synthesis™ Platform

Ribonucleic acid (RNA) as a therapeutic modality has gained tremendous traction in recent years with the growing number of messenger RNA (mRNA) vaccines and small interfering RNA (siRNA) candidates advancing in clinical studies. However, large-scale production of RNA interference (RNAi) therapeutics using traditional chemical synthesis faces complex challenges in nucleic acid quality and quantity, as well as overall economics. With over 450 RNAi therapies currently in clinical development, including more than 40 assets in Phase 2 and Phase 3 clinical trials targeting disease indications impacting millions of patients, RNAi therapeutic demand is projected to outpace current production capabilities by the end of the decade. Codexis’ proprietary ECO Synthesis™ technology platform is being designed to address these scalability and cost limitations by potentially enabling the commercial-scale manufacture of RNAi therapeutics through an enzymatic route. The Company is on track to demonstrate gram-scale synthesis by the end of 2023, where it will demonstrate the preparative-scale manufacture of an oligonucleotide, composed of the modified nucleotide building blocks typically used in RNAi therapeutics, under process-like conditions.
