Treatment with anti-ErbB2 antibodies
The present invention concerns dosages for treatment of human cancer patients with an anti-Epidermal Growth Factor Receptor (EGFR) antibody.
1. A method for the treatment of a human patient diagnosed with breast cancer characterized by 2+ or 3+ overexpression of ErbB2 receptor as determined by immunohistochemistry or fluorescence in situ hybridization (FISH), comprising the steps of administering to the patient an initial dose of 8 mg/kg of anti-ErbB2 huMAb 4D5-8 antibody; and administering to the patient a plurality of subsequent doses of 6 mg/kg of the antibody, wherein all doses are separated in time from each other by three weeks.
2. The method of claim 1 , further comprising administering an effective amount of a chemotherapeutic agent.
3. The method of claim 2 , wherein said chemotherapeutic agent is a taxoid.
4. The method of claim 3 , wherein said taxoid is paclitaxel or docetaxel.
5. The method of claim 4 wherein said taxoid is paclitaxel.
6. The method of claim 1 , wherein said antibody is administered by intravenous injection.
7. A method for the treatment of a human patient diagnosed with breast cancer characterized by 2+ or 3+ overexpression of ErbB2 receptor as determined by immunohistochemistry or fluorescence in situ hybridization (FISH), the method comprising: administering intravenously to the patient an initial dose of 8 mg/kg of anti-ErbB2 huMAb 4D5-8 antibody; and administering intravenously to the patient a plurality of subsequent 6 mg/kg doses of the antibody, wherein the initial dose is separated in time from the first subsequent dose by three weeks, and the subsequent doses are separated from each other in time by three weeks.
8. The method of claim 7 , wherein the intravenous administration is an intravenous infusion.
9. The method of claim 8 , wherein the subsequent doses maintain a trough serum concentration of the anti-ErbB2 huMAb 4D5-8 antibody at or above 10 μg/mL.
10. The method of claim 8 , wherein the subsequent doses maintain a trough serum concentration of the anti-ErbB2 huMAb 4D5-8 antibody at or above 20 μg/mL.
11. The method of claim 7 , wherein the subsequent doses maintain a trough serum concentration of the anti-ErbB2 huMAb 4D5-8 antibody at or above 10 μg/mL.
12. The method of claim 7 , wherein the subsequent doses maintain a trough serum concentration of the anti-ErbB2 huMAb 4D5-8 antibody at or above 20 μg/mL.
