Codexis' Landmark Presentations at TIDES USA Highlight Reproducibility and Process Simplification of the ECO Synthesis Platform for Manufacturing siRNA

May 22, 2025 07:00 ET | Source: Codexis, Inc. Presentations by leading siRNA CDMOs, Bachem, Nitto Avecia, and ST Pharm, highlight performance and transferability of Codexis double-stranded RNA ligases Management to host conference call today at 8 am Eastern Time to discuss data REDWOOD CITY, Calif., May 22, 2025 (GLOBE NEWSWIRE) -- Codexis, Inc. (NASDAQ: CDXS), a leading provider of enzymatic solutions for the efficient and scalable manufacturing of complex therapeutics, presented data at the TIDES USA annual meeting in San Diego, California. Codexis’ presentations showcased its proprietary ECO Synthesis platform’s ability to support siRNA manufacturing by reducing purification costs, improving process performance, and demonstrating the potential to control stereochemistry. In addition, three presentations from contract development and manufacturing organizations (CDMOs) including Bachem, Nitto Avecia, and ST Pharm validated the transferability of Codexis’ ligation processes to their in-house facilities. “Having been on the ground at TIDES this week, it is clear that siRNA technology has officially arrived,” said Stephen Dilly, MBBS, PhD, Chairman and Chief Executive Officer at Codexis. “With a broader shift in favor of enzymatic manufacturing solutions and recent initiatives to onshore manufacturing, the rollout of our ECO Synthesis technology is quite timely. Our presentations at TIDES, including those from our three CDMO collaborators, validate the performance of our enzymatic approach and that the technology is now deployed at larger scale. We also showed how our technology can address some of the constraints associated with existing chemical synthesis methods, including intensive purification steps and lack of control over stereochemistry.” Kevin Norrett, Chief Operating Officer of Codexis, added, “Since the TIDES Europe meeting last fall, Codexis has emerged as the leader in enzymatic technology for manufacturing siRNA. Customers have gone from asking whether an enzymatic approach can work, to now asking how and when they can incorporate it into their drug development. Our job is to translate this momentum into genuine traction, including a GMP scale-up partnership by the end of the year.” Codexis Showcases Improvements in Performance and Process Conditions of ECO Synthesis Platform During an oral Main Stage presentation, Codexis used inclisiran as an example to showcase how the use of immobilized enzymes in its ECO Synthesis platform delivers a consistent process with improved performance. Using sequential enzymatic synthesis, we: Continued to achieve consistent coupling efficiency of >98%Maintained the delivery of high product qualitySuccessfully decreased average cycle time by approximately 24%, translating into reduced production timeDemonstrated high yields of 30 grams of siRNA per liter Using Codexis’ ligase to manufacture siRNA, our data demonstrated the potential to reduce or eliminate costly downstream purification steps. This benefit of ligation has led many companies to explore using this method in siRNA manufacturing. Codexis Highlights Proprietary Machine Learning Tool for Optimized Ligation Codexis’ poster presentation highlighted how the Company’s recently launched machine learning tool is improving the success rate of ligation to produce siRNA. The tool aids process design by guiding the selection of optimal pairings of ligases and RNA fragments and has been shown to significantly outperform traditional fragment selection by four to sixfold. It also increases the probability of identifying fragment designs for which a single ligase can combine all fragments together in one reaction with greater than 90% efficiency. This approach has been validated through test molecules and partner case studies. By accelerating the ligase selection process and maximizing ligation efficiency, this tool demonstrates the potential to reduce process development time, lower costs, and enable an efficient manufacturing process for customers. Three CDMO Collaborator Presentations Feature the Use of Codexis Ligases to Combine Short RNA Fragments In addition to Codexis’ presentations, Bachem, Nitto Avecia, and ST Pharm, three leading CDMOs in siRNA manufacturing, presented data on the use of Codexis ligases to successfully combine short RNA fragments. Each CDMO collaborator performed their ligations in-house, demonstrating that Codexis’ process can be easily transferred and the benefits across yield, purification, and impurity control can be replicated in customers’ hands. Codexis Demonstrates the Potential to Control Stereochemistry in Enzymatic Synthesis of siRNA In a separate TIDES Talk presentation, Codexis highlighted a new feature under development for the ECO Synthesis technology to allow for stereochemical control during oligonucleotide synthesis. Stereochemistry refers to the presence of mirror-image forms, or chirality, of a therapeutic oligonucleotide strand, which can impact the efficacy and stability profile of siRNA therapeutics. Drug developers have little influence over stereochemistry today, as existing chemical manufacturing solutions produce mixtures of these mirror images that vary in terms of therapeutic potency. In contrast, the data in this oral presentation demonstrate how the ECO Synthesis platform can enable control over stereochemistry under process-relevant conditions. This differentiated capability would give customers the choice to define stereochemistry in their oligonucleotide products, potentially benefiting each assets’ therapeutic potency and market position. The slide decks from both of Codexis’ oral presentations and the poster are now available in the Investor Relations section the Codexis corporate website, www.codexis.com/investors. Conference Call and Webcast Codexis management will host a conference call beginning at 8:00 am Eastern Time on Thursday, May 22, 2025, to discuss the data presented during the conference.
