Radiotherapy With Durvalumab Prior to Surgical Resection for HPV Negative Squamous Cell Carcinoma

Patients will receive one dose of neoadjuvant durvalumab 1500 mg approximately 3-6 weeks prior to standard of care surgery. It will be given concurrently with the first dose of radiation (RT). Patients will receive up to six doses of durvalumab and radiation post-operatively.

The starting RT dose level will be given as 6 Gy for 2 fractions (12 Gy total) every other day over approximately one week to sites of gross disease only to minimize exposure to normal tissue. If toxicity develops and surgery is delayed by more than 8 weeks (qualifying as a DLT), the radiation dose will be dropped per protocol for the next set of patients. If this dose is tolerated, the dose will be increased to 6 Gy for 3 fractions (18 Gy total) for the next 3 patients.

Patients will proceed to surgical resection 3-6 weeks after radiation as recommended by the ENT surgeon.
