RZ-001

RNA replacement enzyme vector-based cancer therapy (1st indication: Advanced HCC, RZ-001)

Mechanism of RNA replacement enzyme

Excellence
  • Specific regression of liver cancer cells expressing target RNAs & Specificity enhance by use of pro-drug
  • Efficacy enhancement by suppressing target RNA expression & simultaneously triggering therapeutic gene expression in target cells
  • Optimization of vector dose and minimization of side effects in non-tumor hepatocytes via miRNA regulation
In vivo Toxicity

Hepatocellular toxicity after injection of RZ-001: AST and ALT levels on days 15 and 29 after single intravenous injection of RZ-001 into normal mice

  • Without GCV treatment

    AST and ALT levels of 0.5x10^10 and 1x10^10 VP-injected groups were observed to be at a level similar to those of a PBS-injected group.

  • With GCV treatment

    Pro-drug, GCV, was administered for 10 days after injection of RZ-001.

    AST and ALT levels of 0.5x10^10 and 1x10^10 VP-injected groups were observed to be at a level similar to those of a PBS-injected group.
