OUTLINE: This is a phase II, multi-arm, open-label trial of perioperative atezolizumab alone or in combination with other immune-modulating agents in advanced SCCHN. Based on the results of these initial cohorts, the trial will be amended to explore other novel atezolizumab-based combinations (such as atezolizumab in combination with another immuno-oncology (IO) agent, chemotherapeutics, or a molecularly targeted agent that could potentiate the activity of atezolizumab). Each of these new cohorts will be tested and enrolled to in sequential, non-randomized fashion.
Arm I: Patients receive atezolizumab intravenously (IV) over 30-60 minutes every 3 weeks for up to 2 courses prior to standard surgery and radiation. 16 weeks post-surgery, patients receive atezolizumab IV over 30-60 minutes every 3 weeks for up to 12 courses in the absence of disease progression or unacceptable toxicity.
Arm II: Patients receive atezolizumab IV over 30-60 minutes and another immune-modulating agent yet to be determined, for up to 2 courses prior to standard surgery and radiation. 16 weeks post-surgery, patients receive atezolizumab IV over 30-60 minutes every 3 weeks for up to 12 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 28 days and then periodically for up to 2 years.
