111In-panitumumab

This phase I trial evaluates the safety and effectiveness of using two imaging techniques, indium In 111 panitumumab (111In-panitumumab) with single photon emission computed tomography (SPECT)/computed tomography (CT) and panitumumab-IRDye800 fluorescence imaging during surgery (intraoperative), to detect disease in patients with head and neck cancer. 111In-panitumumab is an imaging agent made of a monoclonal antibody that has been labeled with a radioactive molecule called indium In 111. The agent targets and binds to receptors on tumor cells. This allows the cells to be visualized and assessed with SPECT/CT imaging techniques. SPECT is special type of CT scan in which a small amount of a radioactive drug is injected into a vein and a scanner is used to make detailed images of areas inside the body where the radioactive material is taken up by the cells. CT is an imaging technique for examining structures within the body by scanning them with x-rays and using a computer to construct a series of cross-sectional scans along a single axis. Panitumumab-IRDye800 is an imaging agent composed of panitumumab, a monoclonal antibody, linked to a fluorescent dye called IRDye800. Upon administration, panitumumab-IRDye800 targets and binds to receptors on tumor cells. This allows the tumor cells to be detected using fluorescence imaging during surgery. Adding 111In-panitumumab SPECT/CT imaging to intraoperative panitumumab-IRDye800 fluorescence imaging may be more effective at detecting disease in patients with head and neck cancer.
