Codexis Announces Achievement of Gram-scale Synthesis with its ECO Synthesis™ Platform

Milestone enables Codexis engineers to model the manufacturing process for RNAi therapeutics

Company remains on track to initiate pre-commercial customer testing in 2024

REDWOOD CITY, Calif., Dec. 13, 2023 (GLOBE NEWSWIRE) -- Codexis, Inc., (NASDAQ: CDXS), a leading enzyme engineering company, today announced it has achieved gram-scale synthesis with its Enzyme-Catalyzed Oligonucleotide (ECO) Synthesis™ technology. This critical technical milestone demonstrates the preparative-scale manufacture of an oligonucleotide, composed of the modified nucleotide building blocks typically used in ribonucleic acid (RNA) therapeutics, under process-like conditions.

Successful completion of this milestone enables Codexis engineers to initiate a comprehensive assessment of the purity profile for small interference RNA (siRNA) developed with ECO Synthesis™ technology. Separately, data collected on process-related parameters provides foundational information for early models of the siRNA manufacturing process and allows the Company to open conversations with early access customers on their RNA interference (RNAi) therapeutics manufacturing processes. Early access customer testing is on track to initiate in 2024 ahead of an anticipated full commercial launch in 2026.

“Our scientists have done outstanding work to bring us to this critical milestone for the development of our ECO Synthesis™ technology so rapidly. We have increased production scale by four orders of magnitude since August to move into preparative scale of the oligonucleotide. This is significant because it allows our engineers to begin modeling and testing manufacturing methods with confidence, which will enable us to start sharing data-driven insights with potential customers on key metrics like purity profile,” said Stephen Dilly, MBBS, PhD, Chief Executive Officer of Codexis. “Furthermore, we have demonstrated the ability of our enzymes to include modified building blocks reliably and with high conversion efficiency in a timely fashion. This, together with our steady progress in the enzymatic synthesis of the nucleotide building blocks and starter oligonucleotide, gives us real excitement for the potential of the ECO Synthesis™ platform and we look forward to initiating pre-commercial testing next year.”

The need for an enzymatic route of synthesis for RNAi therapeutics was recently reinforced at the Company’s virtual KOL investor event featuring John Maraganore, PhD, Founder and Former Chief Executive Officer of Alnylam Pharmaceuticals and Codexis Strategic Advisory Board member, and David Butler, PhD, Chief Technology Officer of Hongene Biotech Company. These distinguished experts were joined by Codexis leadership and discussed the growth of RNAi therapeutics as a modality, the manufacturing landscape and the potential role for Codexis’ ECO Synthesis™ platform to enable commercial-scale production of RNAi therapeutics. A replay of the virtual event is accessible on the Investor Relations section of the Company’s website, https://ir.codexis.com.

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 achieved gram-scale synthesis in December 2023, where it demonstrated the preparative-scale manufacture of an oligonucleotide, composed of the modified nucleotide building blocks typically used in RNAi therapeutics, under process-like conditions. Codexis remains on track to initiate early access customer testing in 2024.
