  • Publication number: 20250154286
    Abstract: An human antibody or antigen-binding fragment of a human antibody that specifically binds and inhibits human proprotein convertase subtilisin/kexin type 9 (hPCSK9) characterized by the ability to reduce serum LDL cholesterol by 40-80% over a 24, 60 or 90 day period relative to predose levels, with little or no reduction in serum HDL cholesterol and/or with little or no measurable effect on liver function, as determined by ALT and AST measurements.

  • Publication number: 20250136675
    Abstract: A fully human antibody or antigen-binding fragment of a human antibody that specifically binds and inhibits or interferes with at least one activity of human angiopoietin-like protein 3 (hANGPTL3) is provided. The human anti-hANGPTL3 antibodies are useful in treating diseases or disorders associated with ANGPTL3, such as hyperlipidemia, hyperlipoproteinemia and dyslipidemia, including hypertriglyceridemia, hypercholesterolemia, chylomicronemia, and so forth. Furthermore, the anti-hANGPTL3 antibodies can be administered to a subject in need thereof to prevent or treat diseases or disorders, for which abnormal lipid metabolism is a risk factor. Such diseases or disorders include cardiovascular diseases, such as atherosclerosis and coronary artery diseases; acute pancreatitis; nonalcoholic steatohepatitis (NASH); diabetes; obesity; and the like.
