  • Publication number: 20090226399
    Abstract: In order to obtain high therapeutic effects in treating malignant tumors, particularly melanoma, a new therapeutic method having less side effects, or a new therapeutic method which can provide further high therapeutic effects at conventional doses of agents has been desired. An object of the present invention is to provide a medicament which can provide higher therapeutic effects than any one of a gene recombinant antibody against ganglioside GD3 or the antibody fragment thereof alone, and a substance which activates an immunocomponent cell and a substance having an antitumor activity alone, by combining a gene recombinant antibody against ganglioside GD3 or the antibody fragment thereof with at least one of a substance which activates an immunocomponent cell and a substance having an antitumor activity. Also, the medicament is expected to relieve side effects which were problems in the case of administration of individual single agents.
