Altered expression or constitutive activation of the epidermal growth factor receptor (EGFR/HER1/erbB1) commonly occurs in primary NSCLC, and is often a critical factor in progressive growth and resistance to normal mechanisms of cell death. Epidermal growth factor receptor expression in lung cancer has been correlated with tumor aggressiveness. Clinical trials already suggest that EGFR targeted therapy may improve the antitumor activity of chemotherapy for treatment of lung carcinoma. Monoclonal antibodies specific to EGFR can be combined safely and effectively with chemotherapy. Nimotuzumab (hR3) is a humanized monoclonal antibody (mAb) that binds to the EGFR. In preclinical studies the antibody has shown potent antitumor activity. A previous phase II study in children with high grade brain tumors showed activity of Nimotuzumab as a monotherapeutic agent, even in prognostic very unfavourable diffuse, intrinsic pontine glioma. No drug related side effects were reported. Nimotuzumab (hR3) in combination with radiotherapy for treatment of locally advanced squamous cell carcinomas of the head and neck resulted in high rates of antitumor response, and was accompanied by a favourable safety profile.
