    Epigenetic activation of tumoral INFγ response and pyroptosis overcomes immunotherapy resistance in hepatocellular carcinoma (IDDF 2023)
    Based on these findings, industrial support for the Phase II clinical study of CXD101 plus anti-PD-1 has been secured to provide new epigenetic immunotherapy for ICB-resistant patients. This project is supported by the CRF (C4045-18W), GRF (14115820), TRS (T11-706/18-N), Li Ka Shing Foundation, CUHK Strategic Seed Funding for Collaborative Research Scheme.

    A selective class I HDAC inhibitor recovers intratumoral interferon signaling to overcome immune-checkpoint blockade resistance in hepatocellular carcinoma (P923) (IMMUNOLOGY 2022)
    Moreover, we found a novel selective class I histone deacetylase (HDAC) inhibitor, CXD101, significantly recovered intratumoral IFNγ signaling pathway and synergised with PD-L1 antibody to eradicate tumor and prolong survival in our ICB resistant mouse models. We will further elucidate the epigenetic processes in regulating anti-tumor immunity and the detailed mechanism-of-action of CXD101 plus ICB therapy in our preclinical models, aiming to provide novel mechanism-based immunotherapeutic strategy for HCC patients.

    Immune modulation underpins the anti-cancer activity of HDAC inhibitors. (PubMed, Mol Oncol)
    The altered TME reflected enhanced anti-tumour activity when CXD101 was combined with immune checkpoint inhibitors (ICIs), such as anti-PD1 and anti-CTLA4. The ability of CXD101 to re-instate immune-relevant gene expression in the TME and act together with ICIs provides a powerful rationale for exploring the combination therapy in human cancers.
