  • Publication number: 20110104157
    Abstract: A novel pharmaceutical composition for treating or preventing hepatocellular carcinoma and a method of treatment are provided. A pharmaceutical composition for treating or preventing liver cancer is obtained by combining a chemotherapeutic agent with an anti-glypican 3 antibody. Also disclosed is a pharmaceutical composition for treating or preventing liver cancer which comprises as an active ingredient an anti-glypican 3 antibody for use in combination with a chemotherapeutic agent, or which comprises as an active ingredient a chemotherapeutic agent for use in combination with an anti-glypican 3 antibody. Using the chemotherapeutic agent and the anti-glypican 3 antibody in combination yields better therapeutic effects than using the chemotherapeutic agent alone, and mitigates side effects that arise from liver cancer treatment with the chemotherapeutic agent.

  • Patent number: 7871613
    Abstract: The present invention provides an anti-cancer agent comprising anti-glypican 3 antibody wherein the anti-cancer agent is administered after a cancer treatment, Preferably, after a cancer treatment is after a treatment for liver cancer, and the treatment for liver cancer is in particular a resection of liver cancer cells. The anti-cancer agent according to the present invention is preferably administered if glypican 3 is expressed in the resected liver cancer cells. The anti-glypican 3 antibody is preferably a monoclonal antibody. The anti-cancer agent according to the present invention is useful for preventing cancer and for preventing the recurrence of cancer.
