Mechanism of Action – Dual Lipid Regulation

PCSK9 Inhibition Pathway

  • Molecular Effect: Inhibits PCSK9 expression, increasing low-density lipoprotein receptors (LDLR) on hepatocyte surfaces
  • Primary Outcome: Potent reduction of low-density lipoprotein cholesterol (LDL-C) levels
  • Clinical Relevance: Addresses primary target for cardiovascular risk reduction

ANGPTL3 Inhibition Pathway

  • Molecular Effect: Inhibits ANGPTL3 expression, modulating lipoprotein lipase (LPL) and hepatic lipase (HL) activity
  • Dual Benefits: Further reduces LDL-C while demonstrating excellent triglyceride (TG) and triglyceride-rich lipoprotein (TRL) lowering efficacy
  • Comprehensive Lipid Control: Addresses multiple atherogenic lipid parameters simultaneously

Preclinical Data Foundation

Target Inhibition Results

TargetMaximum Inhibition RateDuration of Effect
PCSK982.21%Up to 12 weeks
ANGPTL394.41%Up to 12 weeks

Lipid Profile Improvements

  • LDL-C Reduction: Significant decrease in low-density lipoprotein cholesterol
  • Triglyceride Reduction: Marked lowering of triglyceride levels
  • Total Cholesterol: Substantial reduction in total cholesterol (TC)
  • Study Duration: Effects sustained through 12-week study endpoint

Strategic Implications

  • Innovation Leadership: Positions Lepu as pioneer in dual-targeting siRNA therapeutics for cardiovascular disease
  • Global Development: Australian trial serves as foundation for international regulatory filings
  • Platform Validation: Success would validate Lepu’s siRNA technology platform for future pipeline candidates
  • Market Differentiation: Dual mechanism offers potential advantages over single-target lipid-lowering agents

Market Context

  • Dyslipidemia Prevalence: Affects over 1 billion people globally with significant cardiovascular risk implications
  • siRNA Therapeutics: Emerging class with demonstrated durability and infrequent dosing requirements
  • PCSK9 Market: Established target with proven cardiovascular benefit but high treatment costs
  • Unmet Need: Limited options for patients requiring both LDL-C and triglyceride reduction
