Abstract
The invention provides a method for increasing the bioactivity (e.g. the biosafety and efficacy) of a therapeutic IgE antibody of the invention in the treatment of a patient. Methods of the invention include: i) administering to the patient a therapeutic IgE antibody in combination with at least one bioactivity-enhancing agent, ii) strategic treatment regimens and protocols for the dosing and administration of a therapeutic IgE antibody of the invention, and iii) the use of a therapeutic IgE antibody having a variable region comprising at least one antigen binding region specific for binding an epitope of an antigen wherein the epitope is not highly repetitive or is non-repetitive.
Claims8
A method for treating cancer in a human patient comprising administering to the patient a therapeutic IgE antibody in combination with at least one immunostimulatory compound wherein the immunostimulatory compound is a TLR3 agonist or a TLR4 agonist;
- and at least one immunosuppressive agent wherein the immunosuppressive agent is a corticosteroid and optionally in further combination with a chemotherapeutic agent wherein the chemotherapeutic agent is gemcitabine, cyclophosphamide, topotecan, or doxorubicin, wherein the IgE antibody is a monoclonal antibody comprising human Fc epsilon (ε) constant regions and a variable region comprising at least one antigen binding region specific for a cancer antigen and wherein the immunosuppressive agent is administered to the patient at least 30 minutes prior to administration of the therapeutic IgE antibody.
A method for treating a tumor in a human patient comprising administering to the patient a therapeutic IgE antibody specific for an antigen associated with the tumor in combination with at least one immunosuppressive agent wherein the immunosuppressive agent is a corticosteroid and at least one immunostimulatory compound wherein the immunostimulatory compound is a TLR3 agonist or a TLR4 agonist and optionally in further combination with a chemotherapeutic agent wherein the chemotherapeutic agent is gemcitabine, cyclophosphamide, topotecan, or doxorubicin, wherein the therapeutic IgE antibody is a monoclonal antibody comprising human Fc epsilon (ε) constant regions and wherein the immunosuppressive agent is administered to the patient at least 30 minutes prior to administration of the therapeutic IgE antibody.
