Monoclonal antibodies (mAbs) to ErbB-2/HER2 growth factor receptor, or to its sibling, the epidermal growth factor receptor (EGFR), prolong survival of cancer patients, especially when combined with cytotoxic therapies. However, low effectiveness of therapeutic mAbs and the evolution of patient resistance call for improvements. Furthermore, the response to the clinically approved monotherapy of Herceptin (a humanized mAb directed against ErbB-2), is relatively low (~15%) and short lived (median duration, 9 months).
Therefore, there is a need to improve the therapeutic treatment against this receptor.
Optimal selection of mAbs for cancer immunotherapy may improve its treatment. The outlined technology addresses an emerging strategy, which enhances the therapeutic activity of anti-receptor antibodies by combining two mAbs engaging distinct epitopes. It was demonstrated that pairs of anti-ErbB-2 mAbs better inhibit ErbB-2-overexpressing tumours than the respective individual mAbs, both in vitro and in vivo.
The present technology enhances the therapeutic activity of anti-ErB-2 receptor antibodies, by combining two or more epitope-distinct antibodies.
