Study of Dacomitinib With Radiotherapy With and Without Cisplatin in Patients With Squamous Cell Carcinoma of the Head and Neck
This is a phase 1 study of investigational drug dacomitinib with radiotherapy and with or without chemotherapy in patients with advanced squamous cell carcinoma of the head and neck (SCCHN).
There are proteins found on the surface of cells called receptors that receive signals and send signals to the cell to grow or to die. Dacomitinib is an oral drug that blocks a receptor called the epidermal growth factor receptor (EGFR) which is found to be too active in SCCHN patients. By blocking the signals for the cancer cells to grow, it is believed to stop or slow the growth of tumor cells. The treatment of SCCHN usually includes chemotherapy and radiation.
This study will have two phases: a dose escalation phase and a dose expansion phase. The dose escalation phase will find the best dose as well as determine the safety of dacomitinib when given with radiotherapy and with or without chemotherapy.The dose expansion phase will further test the best dose determined in the dose escalation phase for safety and effectiveness.
