Patent number: 11760807Abstract: 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.Type: GrantFiled: May 8, 2015Date of Patent: September 19, 2023Assignees: Chugai Seiyaku Kabushiki Kaisha, F.

Patent number: 10426779Abstract: 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.Type: GrantFiled: April 5, 2017Date of Patent: October 1, 2019Assignee: VIRGINIA COMMONWEALTH UNIVERSITYInventors: Ruey-min Lee, Peck-sun Lin

Publication number: 20190083501Abstract: 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.Type: ApplicationFiled: November 9, 2018Publication date: March 21, 2019Inventor: Ruey-min Lee

Patent number: 7781580Abstract: 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.Type: GrantFiled: April 23, 2007Date of Patent: August 24, 2010Assignee: Virginia Commonwealth UniversityInventors: Ruey-min Lee, Daniele Simoni
