  • Patent number: 11760807
    Abstract: A method is provided for determining the efficacy of GPC3-targeting drug therapy for cancer in a patient before the start of GPC3-targeting drug therapy or for determining the continuation of GPC3-targeting drug therapy for a patient treated with GPC3-targeting therapy. The method includes determining the number of an immunocyte or an expression level of a molecule expressed on the immunocyte in a biological sample isolated from the patient before the start of GPC3-targeting drug therapy and/or the patient treated with the GPC3-targeting drug therapy, wherein when the number of the immunocyte or the expression level of the molecule expressed on the immunocyte is a predetermined value, the efficacy of the GPC3-targeting drug therapy is determined or the continuation of the GPC3-targeting drug therapy is determined. GPC3-targeting drugs and drug preparations for use according to the disclosed methods are also provided.

  • Publication number: 20230133566
    Abstract: Disclosed herein are methods and compositions for enhancing an immune response to a solid tumor in a subject. In some embodiments, a method comprises: (a) administering to the subject a hypoxia-activated bioreductive agent (HABA); (b) inducing hypoxia by (i) administering a hypoxia-inducing agent to the subject or (ii) embolizing one or more blood vessels supplying the solid tumor; and (c) administering an immune checkpoint inhibitor prior to, simultaneously with, or subsequent to step (b) in an amount effective to enhance an immune response to the solid tumor, as compared to an immune response in the absence of the immune checkpoint inhibitor. Kits for use in the disclosed methods are also provided.

  • Patent number: 10426779
    Abstract: Methods and compositions for enhancing the ability of hypoxia-activated bioreductive agents to kill tumor cells within solid tumors are provided. Local regions of hypoxia are created within a tumor, or within a region containing a tumor, resulting in enhanced activation of hypoxia-activated bioreductive agents (e.g. tirapazamine) within the local region. The activated hypoxia-activated bioreductive agents kill tumor cells in the hypoxic region by to catalyzing DNA stand breakage within the tumor cells. Because the activity is localized, side effects that typically occur as a result of systemic administration of bioreductive agents are reduced.

  • Publication number: 20190083501
    Abstract: Methods and kits are provided for administering a hypoxia-activated bioreductive agent by applying the agent locally to liver tissue when hepatic arterial pressure is reduced. Local arterial application when pressure is reduced tissue prolongs the duration of tissue exposure to the hypoxia-activated bioreductive agent. Hepatic pressure may be reduced proximal to the liver tissue. In some embodiments, local application may be followed by embolization when arterial pressure is reduced. Embolization under reduced pressure may decrease complications associated with backflow and increase the efficacy of the hypoxia-activated agent.

  • Patent number: 7781580
    Abstract: Stilbene derivatives exhibit killing and suppression of growth activity against a variety of cancer cells, and are effective at suppressing tumor growth in vivo. The stilbene derivatives may be used in the treatment of diseases characterized by cell hyperproliferation including human malignancies and non-malignant diseases such as liver cirrhosis. Stilbenes may also disrupt abnormal vessels in tumor to achieve vascular disrupting effect to suppress tumor growth. Water soluble pro-drug forms of stilbene derivatives are particularly useful in suppressing tumor growth in vivo.
