Study of Proxinium Plus Best Supportive Care Versus Best Supportive Care for Patients With Advanced Head and Neck Cancer

Head and neck cancer is a general description of a disease that includes several types of soft tissue carcinomas that develop in the head and neck regions. Proxinium is a recombinant fusion protein that binds to the epithelial cell adhesion molecule (Ep-CAM) that is highly expressed on squamous cell carcinomas of the head and neck (SCCHN). Proxinium is administered via intratumoural injection. The primary objective of the study is to compare the overall survival time for patients treated with intratumourally injected Proxinium plus BSC versus BSC alone. Secondary objectives of the study include comparison of locoregional tumour control, local progression-free survival, symptomatic benefit and safety profile in patients who receive Proxinium plus BSC versus patients who receive BSC
