  • Publication number: 20200048331
    Abstract: The present invention relates to isolated protein sequences that correspond to cell binding peptides, fragments, neo-structures and/or neo-epitopes of a normally occurring serum protein present in human tissue, wherein the peptide, fragment, neo-structure and/or neo-epitope has an immunoregulatory activity and is the result of either an enhanced proteolytic activity and/or conformational changes in a tissue, or a malignant tumour. In the present patent application, a common structure of several of these peptides, fragments, neo-structures and/or neo-epitopes, having immunoregulatory activity by binding to receptors on immune cells, has been identified. The present invention further also relates to monoclonal and/or polyclonal antibodies directed to a cell binding fragment of a normally occurring serum protein present in human tissue, as described above.

  • Patent number: 9688746
    Abstract: The present invention primarily relates to a method for analyzing the amount of immunoregulatory integrin binding factors and/or patient endogenous antibodies which are directed against such factors, the factors having the capacity to modulate the immune functions in a. subject suffering from cancer or inflammatory or autoimmune diseases, by utilizing binding reagents to determine these factors and/or the patient endogenous antibodies which are directed against such factors, whereby the prognosis and/or the therapeutic efficacy of any treatment of a subject suffering from cancer or inflammatory or autoimmune diseases can be determined and/or monitored. The invention further relates to the use of therapeutically active compounds for eliminating, inhibiting or enhancing such binding factors for the manufacture of pharmaceuticals to be used in the treatment of cancer, inflammatory conditions or autoimmune diseases.

  • Patent number: 6242202
    Abstract: The present invention relates to a method of predicting the therapeutic response of a drug directed towards a cancer in a human patient using samples of blood cells taken from the patient at different times. The method comprises the steps of culturing cells from the samples in a suitable medium; adding a stimulator of proliferation and an immuno-modulating drug of the cells to the culture; and assaying the proliferation of the cells in the culture; comparing the assay of proliferation with a previously made analysis demonstrating correlation between the proliferation of the cells and parameters of the therapeutic response of the drug in the human patient.
