  • Publication number: 20200078453
    Abstract: There is provided according to the invention a method of treating a mammal suffering from or susceptible to an immune reaction to drug treatment comprising the raising of anti-drug antibodies which method comprises (a) ex-vivo treating antigen presenting cells obtained from the mammal with an agent which induces IDO in said antigen presenting cells in the presence of said drug or an epitope containing fragment thereof and (b) after IDO has been induced in said antigen presenting cells, transferring said cells back to the mammal thereby to establish immune tolerance to the drug.

  • Patent number: 6773702
    Abstract: A method of treating immune suppression in a warm-blooded animal bearing a tumor, by administering to the animal an amount of combretastatin A4 and/or a prodrug thereof effective to enhance immune responsiveness without causing vascular destruction. Immunotherapy treatment to inhibit or kill tumor cells includes administering to the animal an immune-response-stimulating agent such as a vaccine of tumor cells genetically modified to produce an immune-response-enhancing cytokine while counteracting tumor-induced immune suppression in the animal by administering combretastatin A4 and/or a prodrug thereof.
    Type: Grant
    Filed: December 26, 2001
    Date of Patent: August 10, 2004
