  • Patent number: 12655212
    Abstract: The present invention relates to humanized anti-claudin-1 antibodies and uses thereof. Hepatitis C virus infection is a leading cause of chronic liver disease and a major indication for liver transplantation. The tight junction protein claudin-1 (CLDN1) is an essential entry factor for HCV and a promising target for therapy. For clinical development, the inventors have humanized a rat anti-CLDN1 antibody produced by genetic immunization that prevent HCV infection and also cure chronically infected human liver chimeric mice. The lead humanized anti-CLDN1 antibody (H3L3) pan-genotypically inhibited HCV pseudoparticle infection of primary human hepatocytes (PHH) without detectable escape. H3L3 efficiently inhibited infection by diverse HCV genotype 3 strains and exhibited marked synergy with direct-acting antivirals (DAAs). The inventors also demonstrate that anti-CLDN1 H3L3 cures persistent HCV infection in human-liver chimeric uPA-SCID mice in monotherapy.

  • Patent number: 12480096
    Abstract: The present invention provides a simple and robust human liver cell-based system in which persistent hepatitis C infection, persistent hepatitis B infection or ethanol exposure induces a clinical Prognostic Liver Signature (PLS) high-risk gene signature. The cellular model system for hepatocellular carcinoma (HCC)/cirrhosis development and progression may be used in the screening of compounds useful in the treatment and/or prevention of cirrhosis and/or HCC as well as in the identification biomarkers for the prediction of liver disease (especially cirrhosis) progression and HCC. The present invention also relates to specific compounds that have been identified, using such screening methods, as useful in the treatment and/or the prevention of HCC/cirrhosis.
