  • Publication number: 20220401556
    Abstract: Methods for producing an anti-tumor effect in a subject suffering from a cancer or a tumor are disclosed. The methods comprise administering to the patient a Vascular Disrupting Agent (VDA) that is a combretastatin agent and one or more antibodies selected from the group consisting of: a CTLA-4 antibody, a PD-1 antibody, a PD-L1 antibody, and a PD-L2 antibody in amounts effective therefor. Examples of combretastatin include CA1P, CA4P, and their corresponding salts and prodrugs. The combination of the VDA and one or more of the antibodies produced a synergistic anti-tumor effect.

  • Patent number: 7456214
    Abstract: Chrome compounds have been discovered which demonstrate impressive cytotoxicity as well as a remarkable ability to inhibit tubulin polymerization. Such compounds as well as related derivatives are excellent clinical candidates for the treatment of cancer in humans. In addition, certain of these ligands, as pro-drugs, may well prove to be tumor selective vascular targeting chemotherapeutic agents or to have vascular targeting activity resulting in the selective prevention and/or destruction of nonmalignant proliferating vasculature.

  • Patent number: 7384925
    Abstract: Novel stilbenoid compounds and their prodrug forms are disclosed, which serve as potent vascular targeting agents useful for the treatment of solid tumor cancers and other diseases associated with unwanted neovascularization. The novel stilbenoid compounds are tubulin-binding stilbenoid analogs structurally related to combretastatin A-1 and combretastatin A-4. The prodrug forms serve as potent vascular targeting agents (VTAs) useful for the treatment of solid tumor cancers and diseases associated with retinal neovascularization.

  • Patent number: 7091240
    Abstract: A diverse set of tubulin binding agents have been discovered which are structurally characterized, in a general sense, by a semi-rigid molecular framework capable of maintaining aryl-aryl, pseudo pi stacking distances appropriate for molecular recognition of tubulin. In phenolic or amino form, these ligands may be further functionalized to prepare phosphate esters, phosphate salts, phosphoramidates, and other prodrugs capable of demonstrating selective targeting and destruction of tumor cell vasculature.
