anti idiotypische monoclonal antibodies, their use for the active immunotherapy of malignant tumors, and compositions containing them

摘要

Monoclonal anti-idiotype antibody which is specific for murine antibodies against gangliosides carrying N-glycolylated sialic acid particularly against those gangliosides which are expressed by tumoral cells. The monoclonal antibody is useful as immunomodulator for the treatment of cancer. Specifically, the monoclonal anti-idiotype antibody of the present invention is capable of inducing a response which is predominantly anti-idiotypic in xenogenic models. The monoclonal anti-idiotype antibody also exerts a protector effect against malignant tumors in animals
