A pathway to reduce these risks involves targeting PCSK9 (proprotein convertase subtilisin/kexin type 9), a protein which downregulates the LDL receptor and therefore reduces uptake of LDLc.

Key Points: 
  • A pathway to reduce these risks involves targeting PCSK9 (proprotein convertase subtilisin/kexin type 9), a protein which downregulates the LDL receptor and therefore reduces uptake of LDLc.
  • Neutralizing PCSK9 by induction of specific antibodies, results in reduced LDLc levels via an increased density of the LDL receptor.
  • Participants were evaluated over a period of 90 weeks to assess safety, immunogenicity, and LDLc-lowering activity of both SAIT products targeting PCSK9.
  • The Company's ultimate goal is to improve the lives of patients suffering from these diseases by providing disease-modifying specific immunotherapies.
