DNA-based delivery of antiviral antibodies for Zika and Influenza prevention

In plain English

AI plain-English summary

A single injection could turn a person's own muscle cells into a factory churning out antibodies against Zika or flu, bypassing the need for repeated doses of manufactured antibodies. Current antibody therapies are expensive and require frequent infusions, limiting their use in outbreaks or low-resource settings. RenBio's approach uses a small electric pulse to deliver DNA instructions directly into muscle tissue, prompting the body to produce its own protective antibodies for weeks or months. This could slash manufacturing costs and dosing frequency, making preventative antibody treatments far more accessible. If successful, the first aim would complete the preclinical safety studies needed to move a potent anti-Zika antibody toward human trials, complementing an existing US government-funded programme. The second aim tackles a harder problem: delivering multiple antibodies at once to prevent influenza, which mutates rapidly. Proof-of-concept in animal models would identify and resolve technical hurdles for cocktail delivery. The immediate impact is on medical supply chains and outbreak response—stockpiling DNA plasmids is cheaper and more stable than storing biological antibodies. If the platform works for both viruses, it could be adapted for other infectious diseases, fundamentally changing how we deliver passive immunity.

View original technical description
RenBio proposes a two-pronged approach to evaluate the applicability of MYO Technology for DNA-based antiviral antibody delivery, using antibodies directed against Zika virus (ZIKV) and influenza A virus (IAV). The MYO Technology platform uses intramuscular electroporation to efficiently deliver antibody-encoding plasmid DNA to muscle cells, which then produce and secrete the antibody, delivering it to systemic circulation. Multiple proof-of-concept animal studies, including an IAV challenge study, have demonstrated efficacy with this approach, which has the potential to greatly improve access to antibodies by reducing costs and dosing frequency. The two aims of this proposal are to 1) complete IND-enabling preclinical activities to support the development of a potent anti-ZIKV antibody, and 2) evaluate the potential for the delivery of cocktails of anti-IAV antibodies for the prevention of disease. The first aim would complement an ongoing program partially funded by the US government via the Defense Advanced Research Projects Agency and conducted in collaboration with academic partners. The second aim would result in an assessment and mitigation of technical hurdles associated with DNA-based delivery of antibody cocktails, with proof-of-concept data generated in animal models of IAV infection. These two aims have the potential to significantly impact ZIKV and IAV disease prevention.
