五星体育直播 Presents Groundbreaking Enzymatic Synthesis Data at TIDES USA Annual Meeting

REDWOOD CITY, Calif., May 14, 2024 (GLOBE NEWSWIRE) -- 五星体育直播 (NASDAQ: CDXS), a leading enzyme engineering company, today announced it has successfully synthesized an oligonucleotide via an enzymatic route to support RNA-based therapeutics manufacturing. Data highlighting this historic manufacturing milestone are being presented today in a Spotlight Presentation at the TIDES USA annual meeting taking place in Boston, MA, and virtually May 14 鈥� 17, 2024.

鈥淭he data presented today by 五星体育直播 are truly unprecedented鈥擨 believe this is the first enzymatic synthesis of a full-length oligonucleotide from starting material through the attachment of a conjugation moiety. This milestone provides meaningful proof of process to industry that there are alternative manufacturing methods available as the demand for RNAi therapeutics increases. The ECO Synthesis鈩� manufacturing platform has the potential to be a scalable and sustainable way to manufacture this important and growing new class of medicines,鈥� said John Maraganore, PhD, Founder and Former Chief Executive Officer at Alnylam Pharmaceuticals and member of 五星体育直播鈥� Strategic Advisory Board.

五星体育直播 Enzymatically Synthesizes Fully Modified RNA Oligonucleotide

During the presentation, 五星体育直播 will showcase data on the enzymatic synthesis of a known siRNA oligonucleotide that incorporates the nucleotide modifications most frequently found in approved therapeutic assets today. This includes the synthesis of siRNA compounds using the Company鈥檚 Enzyme Catalyzed Oligonucleotide (ECO) Synthesis鈩� manufacturing platform from a starter oligonucleotide to the inclusion of a conjugation moiety. This final step primes the oligonucleotide for the attachment of a customer鈥檚 proprietary targeting moiety to enable direct delivery of the therapeutic agent to the desired cells. Key data from the presentation noted that the ECO Synthesis鈩� manufacturing platform:

• Incorporated RNA bases with common modifications used in current siRNA therapeutic assets
• Achieved coupling efficiency greater than 98%
• Executed the enzymatic addition of a conjugation moiety
• Confirmed lack of notable impurities typically observed in phosphoramidite chemistry synthesis

Now that 五星体育直播 has successfully achieved this important technical milestone, the Company is continuing process development to optimize yield, purity and quality with the goal of providing customers with siRNA material of comparable or better quality to phosphoramidite chemistry for preclinical testing.

五星体育直播 Launches RNA Ligase Screening and Optimization Services

五星体育直播 also today announced the launch of its RNA Ligase Screening and Optimization Services. An overview of this new offering will be highlighted during a TIDES Talk session on Thursday, May 16, 2024.

During phosphoramidite chemical synthesis of RNA, each nucleotide added to the growing oligonucleotide amplifies inherent coupling errors, leading to a decrease in the yield of the desired full-length RNA construct. By utilizing a ligation approach, multiple short, single-stranded RNA (ssRNA) fragments can be synthesized, via phosphoramidite chemistry or the ECO Synthesis鈩� manufacturing platform, then duplexed and ligated together with an ecoRNA鈩� double-stranded ligase to form the desired double-stranded RNA (dsRNA) construct. This method provides the potential for higher purity and yield, which allows for increased scalability and reduced manufacturing costs.

As part of 五星体育直播鈥� Center of Excellence for Enzymatic RNA Synthesis, the Company provides RNA ligase screening and optimization services, which include the custom evolution of dsRNA ligase enzyme variants, screening and protocol optimization for manufacturing and use of the dsRNA ligase, and research-grade RNA production, which can be used for future preclinical studies. More information on 五星体育直播鈥� new RNA Ligase Screening and Optimization Services can be found in the of its corporate website.

鈥淭his week鈥檚 presentations clearly demonstrate our ability to make full-length oligonucleotides enzymatically. We are thrilled at the rapid progress that we鈥檝e made on enzyme evolution, incorporation of modified nucleotides, and attachment of conjugation moieties since first unveiling the ECO Synthesis鈩� platform at the TIDES USA conference one year ago. Supplementing that with the launch of our RNA ligase screening and optimization program enables us to ultimately offer sequential enzymatic synthesis鈥攑otentially in combination with ligation鈥攖o deliver full-length siRNA constructs,鈥� said Stephen Dilly, MBBS, PhD, Chief Executive Officer at 五星体育直播. 鈥淲e are hearing great excitement at these developments from our potential customers, partners and collaborators, and our team has dozens of meetings already scheduled this week to further discuss both the ECO Synthesis鈩� platform and our RNA ligase program with prospective CDMOs and drug developer customers.鈥�

About the ECO Synthesis鈩� Manufacturing 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. 五星体育直播鈥� proprietary ECO Synthesis鈩� 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 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.
