The recommended dose is 800 mg given as an intravenous infusion over 60 minutes on Days 1 and 8 of each 3-week cycle.
Necitumumab belongs to a group of biologic substances called monoclonal antibodies. It recognizes and binds specifically to a protein on the surface of some cancer cells. The protein is known as an epidermal growth factor receptor (EGFR). Other body proteins (called growth factors) can attach to the EGFR and stimulate the cancer cell to grow and divide. Necitumumab stops other proteins from binding to the EGFR and can prevent the cancer cell from growing and multiplying.
