  • Publication number: 20070155693
    Abstract: The subject of the present invention is to provide means to fully achieve the inhibition of cancer bone metastasis, which was accomplished through the repeated selection of agents with aiming at obtaining more beneficial effects on the inhibition of cancer bone metastasis. The invention is achieved by combining an inhibition substance of the activation of osteoclast caused by the degradation of a signaling molecule, TRAF6, in the activation of osteoclast, a suppressive substance of the differentiation from osteoclast precursor cells to mature osteoclasts, and/or a bone resorption inhibitor and/or a Cox2 synthesis inhibitor. This combination was found to have an extremely high utility for the inhibition of cancer bone metastasis.

  • Publication number: 20070154452
    Abstract: The present invention is aiming to provide further advantageous effects on treating pancreas cancer, thus providing the means therefor is the subject. The present invention was obtained by finding that there were differences in prognosis in accordance with intrinsic IL-12-producing ability when Novel Immunotherapy for Cancer (NITC) was conducted in targeting pancreatic cancer cases, and further finding that extremely high effects could be obtained on pancreatic cancer therapy by selecting a therapy based on examination results of the level of intrinsic IL-12-producing ability. Therefore, the present invention is to provide an examination method to predict prognostic effects in immunotherapy for pancreas cancer, comprising determination of intrinsic IL-12-producing ability, and a therapeutic agent for pancreas cancer based on that.

  • Publication number: 20060067947
    Abstract: There is provided means for increasing complete remission rates and shortening a period to complete remission and for achieving a synergistic effect with immunotherapy that is directed at bringing about enhanced effects from molecule-targeting therapeutic drugs. More specifically, an object is to achieve a synergistic effect by combining use of a novel immunotherapy for cancer that focuses on CTL activity, NKT activity, NK activity and ?VEGF and the like, and molecule-targeting therapeutic drugs, particularly tyrosine kinase inhibitors. The present invention was accomplished based on the finding that combined use of a tyrosine kinase inhibitor and an IL-12 inducer achieves a superior synergistic effect in cancer therapy.
