An Orthogonal Array Optimization of Lipid-like Nanoparticles for mRNA Delivery in Vivo.


ABSTRACT: Systemic delivery of mRNA-based therapeutics remains a challenging issue for preclinical and clinical studies. Here, we describe new lipid-like nanoparticles (TT-LLNs) developed through an orthogonal array design, which demonstrates improved delivery efficiency of mRNA encoding luciferase in vitro by over 350-fold with significantly reduced experimental workload. One optimized TT3 LLN, termed O-TT3 LLNs, was able to restore the human factor IX (hFIX) level to normal physiological values in FIX-knockout mice. Consequently, these mRNA based nanomaterials merit further development for therapeutic applications.
