Develop and optimize biodegradable lipid nanoparticle formulations specifically tailored for intramuscular mRNA vaccine delivery to improve tolerability while maintaining potent immune responses.
Screened a panel of proprietary biodegradable ionizable lipids for protein expression and immunogenicity following intramuscular delivery in rodents.
Evaluated selected candidate formulations for tolerability, expression, and immunogenic profiles in both rodent and non-human primate models.
Identified a lead lipid nanoparticle formulation that elicited robust immune responses with significantly improved tolerability profiles.
Demonstrated that higher lipid nanoparticle–driven innate immune stimulation does not correlate with improved immunogenicity, showing potency can be preserved alongside lower reactogenicity.
