Project OverviewWe have previously developed Rolling Circle Amplification (RCA) to rapidly produce gram quantities of DNA that can be utilized as is, or converted to RNA for therapy needs. We have experience in industrializing manual workflows and fabricating functionally closed automated systems to perform multi-step scaleup of biologics along with in-line QC, compatible with GMP requirements. This paired with rapid milligram- to gram-scale biosynthetic production of DNA and RNA constructs from initial templates enables the capability to rapidly produce nucleic acid-based therapeutics on-demand at the point of need.

DNA vaccines and immunotherapeutics: Clinical successes and preclinical advancements

DNA plasmids are usually delivered by intramuscular injection. This plasmidDNA is taken into cells at the site of injection and transcribed and translatedintracellularly. The resulting protein is secreted from transformed cells andprocessed and presented on major histocompatibility complex-1 (MHCI)molecules for presentation to CD8+ T cells (cytotoxic T lymphocytes, orCTLs). Secreted protein antigen can activate B lymphocytes directly or bephagocytosed and presented to CD4+ T cells on MHCII to promote humoralimmunity (Fig. 1). Advanced delivery methods such as gene gun deliveryand electroporation (EP) (Fig. 1c) have enhanced the immunogenicity of theDNA platform.

DNA vaccines targeting emerging and re-emerging infectiousdiseases have had recent clinical success. These include DNA vaccinestargeting ZIKA virus (ZIKV), Ebola virus (EBOV), and Middle East respiratorysyndrome coronavirus (MERS-CoV).The ability to generate syntheticconsensus (SynCon) sequences make the platform useful for generatingimmune responses against pathogenic proteins which exhibit antigenicvariation or for which there are multiple variants or serotypes in the targetpopulation. SynCon DNA technology also allows for the generation of cellularand humoral responses against self-antigens which may be overexpressedby cancerous or pathogenic tissues. Finally, the ability to express complexbiological molecules using the DNA platform is of important clinicalsignificance. DNA encoded monoclonal antibodies (dMAbs) and bi-specificT-cell engagers (dBiTEs) has shown great promise in preclinical studies.
