Ai-assisted design of lnps for effective cns delivery of rna

Lipid nanoparticles (LNPs) have emerged as a promising delivery vehicle for realizing the therapeutic potential of RNA. Developing effective extrahepatic-targeting LNP formulations has been elusive, however, particularly when targeting the central nervous system (CNS). This work demonstrates the ability of AiLNP, METiS' proprietary AI-driven organ-targeted LNP discovery engine, to rapidly (<2 months) create proprietary LNPs specifically optimized for CNS delivery. AiLNP-designed LNPs loaded with siRNA achieved >80%knockdown of HTT mRNA in the whole brain of adult mice after a single intrathecal dose of 0.75 mg/kg siRNA, while naked siRNA was unable to achieve knockdown at any dose. Tissue microscopy found that the optimized LNPs uniformly delivered siRNA to deep brain regions in the cortex, hippocampus, and cerebellum. The LNPs showed clear signs of safety, with no hematologic toxicity, systemic bleeding, or body weight changes. Beyond siRNA, AiLNP has also been applied to optimize LNPs for CNS delivery of mRNA and ASOs. These results highlight the potential of AiLNP to significantly improve the design of LNPs that can successfully deliver payloads to the CNS.
