  • Publication number: 20230183297
    Abstract: The present invention relates to methods of treating a disease characterised by aberrant cell proliferation (e.g., a cancer) in a human subject in need thereof. In particular, the present invention relates to treating the above conditions by administering a therapeutically effective amount of at least one agent that increases activation of a receptor of at least one type II interferon and/or type I interferon, and administering to the subject at least one agent that inhibits the Hedgehog (Hh) signalling pathway (e.g., Vismodegib). Also provided are pharmaceutical compositions, including controlled release pharmaceutical compositions, containing at least one agent that increases activation of a receptor of at least one type II interferon and/or type I interferon (e.g., a checkpoint inhibitor), an inhibitor of Hh signalling pathway, and a controlled release matrix such as a SiO2 matrix gel.
