Summary
Mouse tests showed FL0445-LNP delivered both linear mRNA and capped circular RNA encoding GLP-1, with the circular construct producing stronger functional activity than linear mRNA.
The platform raised mRNA activity about 10-fold versus conventional lipid nanoparticles while triggering negligible inflammation, a key hurdle for repeatable RNA therapies.
Nagoya University’s Cap-cirRNA is designed to pair circular RNA’s greater durability with improved translation, while FUJIFILM’s branched biodegradable lipid aims to handle RNA cargos with different shapes and sizes.
The work suggests longer-lasting RNA medicines could reduce dosing frequency for protein therapies and support broader uses in vaccines, cancer immunotherapy and genome editing, though human use still needs optimization on dose, distribution and safety.
