A dynamic
biological challenge

Nucleic acid vaccines have come a long way since their first use in preclinical experiments. Major advances in capping, delivery, manufacturing, and non-natural nucleosides enabled the field to grow.

These solutions, while game-changing, have all focused on engineering the chemistry and delivery of nucleic acids.

biological solution

ExcepGen's RNAx platform addresses the cellular response to nucleic acids. RNAx is an mRNA encoded protein that alters the way that cells respond to RNA and LNPs by dampening an overactive innate immune response. Read our recent publication here.
