A Study of STX-1150 in Participants With Elevated Low-Density Lipoprotein Cholesterol (LDL-C)

Summary

STX-1150 is an investigational therapy designed to lower LDL-C by silencing a gene called PCSK9 in the liver. STX-1150 does not edit or permanently change the gene. STX-1150 comprises an mRNA and guide RNA (gRNA) delivered via lipid nanoparticles (LNP) for intravenous infusion. The mRNA produces a protein that switches off the PCSK9 gene expression without altering the DNA sequence. This process leverages natural mechanisms that regulate gene activity. The study will enroll up to 64 participants with elevated LDL-C across sites in Australia and New Zealand. The follow-up period will be up to 1- year post-treatment.
