CDXS Codexis Inc

Codexis, Inc. (NASDAQ: CDXS), a leading provider of enzymatic solutions for efficient and scalable therapeutics manufacturing, today announced the Company will demonstrate real-world application of its enzymatic synthesis platform via three presentations at the upcoming TIDES Europe annual meeting, being held November 12-14, 2024, in Hamburg, Germany. Codexis management will hold an investor conference call at 4:30 pm Eastern Time on November 14, 2024, to review and discuss the data presented.

In a joint poster with Bachem, one of the world’s leading CDMOs in siRNA manufacturing, Codexis will feature data demonstrating the superiority of its double-stranded RNA ligase variants compared to wild-type enzymes. The company will also participate in two oral presentations. On Wednesday, November 13, 2024, a TIDES Talk will showcase the extensive capabilities of Codexis’ RNA Ligase Screening & Optimization Services, including data from real customer case studies. On Thursday, November 14, 2024, a Spotlight Presentation will showcase the abilities of the Company’s proprietary Enzyme Catalyzed Oligonucleotide (ECO) Synthesis™ manufacturing platform utilizing various combinations of sequential enzymatic synthesis, traditional phosphoramidite chemistry and enzymatic ligation to produce a commercially available siRNA therapeutic. This public demonstration will further highlight the flexibility and broad applicability of the ECO Synthesis™ platform to the manufacture of siRNA therapeutics.

Attendees of the conference may visit with the Codexis team at Booth #709 in the exhibition hall. Appointments may be made in advance by contacting the business development team.

About RNAi Therapeutics Manufacturing

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.

About the ECO Synthesis Manufacturing Platform

Codexis’ proprietary Enzyme Catalyzed Oligonucleotide (ECO) Synthesis™ manufacturing 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 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.
