Abstract

The tremendous success of mRNA vaccine during the COVID-19 pandemic has captured attention globally and highlighted the transformative potential of mRNA technology in addressing infectious diseases. In comparison to conventional protein antibody-based therapies, the delivery of mRNA-encoding antibodies presents a cost-effective and versatile approach with several advantages. These include eliminating the laborious process of in vitro protein expression, enabling flexible manufacturing processes, and eliciting rapid therapeutic responses. However, the clinical application of mRNA-encoded antibodies for infectious diseases remains limited to date, only one such construct—mRNA-1944—has been assessed in non-human primates and approved for phase I clinical trial. Several challenges hampered the broader clinical application of mRNA-encoded antibody therapies, including the requirement for higher dosages for intravenous administration, limited pharmacodynamic and pharmacokinetics data, as well as the lack of safety and efficacy profiles in non-human primates.
