2022 Business Highlights

Corporate Highlights

In November 2022, Codexis announced a plan to prioritize time and resources on areas where the Company believes it has the strongest commercial opportunity and greatest probability of success. As part of this plan, the Company decided to discontinue investment in certain internal development programs, expand investment in high potential development programs, and realign its workforce.
Throughout 2022 and early 2023, the Company strengthened its management team and Board of Directors with individuals who possess the strategic acumen, operational experience, and commercial mindset to deliver on its prioritized corporate goals. These changes include the addition of Dr. Stephen Dilly as President and CEO, Kevin Norrett as Chief Operating Officer, Sri Ryali as Chief Financial Officer, Meg Fitzgerald, JD, as Chief Legal Officer and General Counsel, and the additions of both H. Stewart Parker and Rahul Singhvi, ScD, to the Board of Directors.

Life Sciences

In February 2023, at the Advances in Genome Biology and Technology (AGBT) General Meeting, Codexis launched a newly engineered DNA ligase for next-generation sequencing, or NGS. Subsequently, Roche exercised its right of first negotiation (ROFN) on the newly engineered DNA ligase. For additional details, please see the white paper available at https://www.codexis.com/resources/detail/11503/a-ligase-with-superior-ligation-efficiency.
In August 2022, Codexis and Molecular Assemblies, Inc. (MAI) announced the execution of a Commercial License and Enzyme Supply Agreement, enabling MAI to utilize an evolved terminal deoxynucleotidyl transferase (TdT) enzyme in MAI's Fully Enzymatic Synthesis™ (or FES™) technology. The companies collaborated to develop this TdT enzyme to advance fully enzymatic DNA synthesis for the production of long, pure, accurate oligonucleotides to accelerate innovation in many fields.
In April 2022, Codexis announced a partnership and strategic investment with seqWell, Inc., a developer of transformative library preparation products for next generation sequencing applications.

Biotherapeutics

In February 2023, Codexis announced interim results from the Phase 1 clinical trial of CDX-7108, which is being co-developed with Nestlé Health Science S.A., for the treatment of exocrine pancreatic insufficiency (EPI). Data from five subjects with EPI in the proof-of-concept arm indicated improved lipid absorption when patients are administered CDX-7108 versus placebo. Importantly, no safety issues were noted in the 48 healthy subjects that participated in the single ascending dose and multiple ascending dose portion of the study.
In February 2023, Takeda Pharmaceutical Company Limited (Takeda) presented pre-clinical data from the Fabry disease transgene program, part of its Strategic Collaboration and License Agreement with Codexis, at the 19th Annual WORLDSymposium™. The gene therapy candidate is being developed to encode the codon optimized, CodeEvolver® engineered a-GAL enzyme, which is designed to have improved serum and lysosomal stability and a predicted reduced immunogenicity.

Pharmaceutical Manufacturing

In September 2022, Codexis hosted its 2022 Protein Engineering Forum, bringing more than 100 top scientists and innovators together for presentations and networking events to facilitate the sharing of insights and recent technological advancements throughout genomics, nucleic acid synthesis and synthetic biology.
In June 2022, Merck and Codexis published a paper in the peer-reviewed journal Science, detailing the development of a suite of enzymes and their application for site-selective synthesis of insulin bioconjugates. The publication describes the development and optimization of enzymes using the CodeEvolver® technology platform.

Upcoming Milestones

Phenylketonuria (PKU): The Company anticipates that its partner Nestlé Health Science will file an Investigational New Drug (IND) application for CDX-6114 for PKU, one of the most common inborn errors of metabolism (IEM) in the second half of 2023.
Exocrine Pancreatic Insufficiency (EPI): The Company anticipates that Nestlé Health Science will file an IND application for the Phase 2 study of CDX-7108 for the treatment of EPI by the end of 2023. The Phase 2 study is expected to be conducted over approximately 12 months, with topline data anticipated in 2025.
Fabry disease: The Company anticipates that its partner Takeda will file an IND application for a Phase 1 study in Fabry disease as soon as late 2023.
