Codexis to Participate in Enzymatic Synthesis Presentations at RNA Leaders Annual Meeting

REDWOOD CITY, Calif., Aug. 20, 2024 (GLOBE NEWSWIRE) — Codexis, Inc. (NASDAQ: CDXS), a leading enzyme engineering company, today announced the Company will participate in a presentation and panel discussion at the upcoming RNA Leaders annual meeting, being held September 4-5, 2024, in San Diego, CA. The Company’s presentations will focus on the use of enzymes to drive the scalable and cost-effective manufacture of short inhibitory ribonucleic acid (siRNA) duplexes. During a keynote panel presentation, Stefan Lutz, PhD, Codexis Senior Vice President of Research, in addition to other RNA industry leaders, will discuss how the biopharmaceutical industry is developing new solutions to advance RNA manufacturing, address production capacities and establish new approaches to streamline clinical trials and standardize protocols. The Company’s second presentation will focus on ligation, which enables the joining of siRNA fragments to generate full-length siRNA duplexes. This approach reduces the overall costs of siRNA manufacturing by leveraging the inherent benefits of short fragment synthesis, including higher yield and increased purity. Codexis recently launched its double-stranded RNA ligase screening and optimization services, and the Company’s presentation will demonstrate improvements across key ligase attributes critical for siRNA manufacturing utilizing its Enzyme Catalyzed Oligonucleotide (ECO) Synthesis™ manufacturing platform. These include high catalytic activity at high substrate loading, as well as improved performance on challenging sequences and modification near ligation junctions. Additionally, improvements in manufacturability of double-stranded RNA ligases are expected to result in a more reliable and scalable enzyme supply. Attendees of the conference may visit with the Codexis team at Booth #9 in the exhibition hall. Appointments may be made in advance by clicking here. Presentation Details Keynote Panel: Scaling RNA Therapies to Deliver on the Promise of Precision MedicineDate: Wednesday, September 4, 2024Time: 10:15 – 10:55 am Pacific Daylight Time (PDT)Location: San Diego Convention Center, San Diego, CACodexis Speaker: Stefan Lutz, PhD, Senior Vice President of Research Presentation Title: Cost-effective Manufacturing of siRNA Duplexes at High Yield and Purity Using Engineered Double-stranded RNA LigasesDate: Wednesday, September 4, 2024Time: 11:45 am – 12:10 pm Pacific Daylight Time (PDT)Location: San Diego Convention Center, San Diego, CACodexis Speaker: Mathew Miller, PhD, Director, Life Science & RNA Technology 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. About Codexis Codexis is a leading enzyme engineering company leveraging its proprietary CodeEvolver® technology platform to discover, develop and enhance novel, high-performance enzymes and other classes of proteins. Codexis enzymes solve for real-world challenges associated with small molecule pharmaceuticals manufacturing and nucleic acid synthesis. The Company is currently developing its proprietary ECO Synthesis™ manufacturing platform to enable the scaled manufacture of RNAi therapeutics through an enzymatic route. Codexis’ unique enzymes can drive improvements such as higher yields, reduced energy usage and waste generation, improved efficiency in manufacturing and greater sensitivity in genomic and diagnostic applications.
