Abstract:
The present invention provides monoclonal IgE antibodies comprising Fc epsilon (ε) constant regions and variable regions comprising at least one antigen binding region specific for binding a single epitope of a circulating, tumor-associated antigen (TAA) that is not a cell surface antigen wherein the epitope of the targeted antigen is not highly repetitive or is a non-repetitive epitope. The IgE antibodies of the invention are useful in the treatment of cancer associated with the tumor antigen. In one embodiment the TAA is prostate-specific antigen (PSA).
