COA of ORNA lipid 144(1-C)

Description:

ORNA lipid 144​​ is a novel ionizable lipid engineered for splenic RNA delivery developed by ORNA Therapeutics, featuring a biodegradable structure with a protonatable tertiary amine headgroup and ester-linked branched C14 alkyl chains. This design enables exceptional spleen-targeting capability, demonstrated by 3-fold higher luciferase expression in the spleen compared to benchmark lipids and near-complete B-cell depletion when delivering anti-CD19 CAR circRNA. It forms highly stable lipid nanoparticles maintaining homogeneous size (60–80 nm) and low polydispersity across diverse manufacturing conditions and buffer systems. Rapid clearance from the liver and spleen minimizes off-target accumulation, while high circRNA encapsulation efficiency (>90%) and pH-dependent endosomal escape make it ideal for immunotherapies and vaccines requiring precise splenic bioavailability and sustained efficacy.
