89Zr-Panitumumab for Assessment of Suspected Metastatic Lesions on 18F-FDG-PET/CT in HNSCC

Phase II Study Evaluating Zr-Panitumumab for Assessment of Suspected Metastatic Lesions on 18F-FDG-PET/CT in Head and Neck Squamous Cell Carcinoma

The purpose of this study is to determine the diagnostic utility of 89Zr-panitumumab to identify metastatic lesion(s) in subjects with head and neck squamous cell carcinoma (HNSCC).

Study Overview

• Status: Withdrawn
• Conditions: Head-and-neck Squamous Cell Carcinoma

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Sensitivity and Specificity of 89Zr-panitumumab	The total number of head and neck squamous cell carcinoma-involved incidental lesions will be determined and correlated to the radiologically suspicious lesions identified by 89Zr-panitumumab using PET/CT imaging.	Up to 1 year

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Sensitivity and Specificity 89Zr-panitumumab compared to standard of care 18F-FDG PET/CT imaging	The total number of head and neck squamous cell carcinoma-involved incidental lesions will be determined and correlated to the radiologically suspicious lesions identified by 18F-FDG using PET/CT imaging. The specificity and sensitivity of 89Zr-panitumumab will be compared to the specificity and sensitivity of 18F-FDG for identification of metastatic lesions.	Up to 1 year
