(89Zr Panitumumab) With PET/CT for Diagnosing Metastases in Patients With Head and Neck Squamous Cell Carcinoma

PRIMARY OBJECTIVE:

• Determine the sensitivity and specificity of zirconium Zr 89 panitumumab (89Zrpanitumumab) for the detection of indeterminate metastatic lesions in head and neck squamous cell carcinoma.

SECONDARY OBJECTIVE:

• Compare sensitivity and specificity of standard of care imaging modalities (magnetic resonance imaging [MRI], CT and/or fludeoxyglucose F-18 [18F]-PET/CT) to 89Zr-panitumumab-PET/CT for detection of indeterminate metastatic lesions in head and neck squamous cell carcinoma.

EXPLORATORY OBJECTIVE:

• Determine rate of intervention (e.g., biopsy or other invasive procedures) versus (vs) non-intervention (e.g., serial imaging, observation) by treatment team in subjects with indeterminate metastatic lesions on standard of care imaging.

OUTLINE:

Patients receive panitumumab intravenously (IV), 89Zr panitumumab IV, and undergo PET/CT on study.
