Phase Ib Study of a Monoclonal Antibody to OX40 (MEDI6469) Administered prior to Definitive Surgical Resection in Patients with Locoregionally Advanced, Oral Head and Neck Squamous Cell Carcinoma

This phase Ib clinical trial uses MEDI6469 at various dose intervals prior to definitive surgical resection of patients with stage III and IV Oral Head and Neck Squamous Cell Carcinoma (OHNSCC) with the primary objective of determining the safety and feasibility of preoperative MEDI6469 administration. In addition, tumor tissue and peripheral blood will be obtained for exploratory immunologic end points including measurements of tumor infiltrating immune cell populations based on flow cytometry and immunohistochemistry as well as circulating immunological parameters that may correlate with changes induced by MEDI6469 administration.

Inclusion Criteria:

* Patients with treatment naive, resectable, stage III or IV squamous cell carcinoma of the oral cavity, oropharynx, hypopharynx or larynx who are candidates for definitive surgical resection followed by standard risk adapted adjuvant therapy.

* Histologic or cytologic diagnosis of a primary OHNSCC with no radiological evidence of metastatic disease is acceptable. Patients with bone or cartilage invasion and any T or N stage are acceptable.

* Patients with oral cavity primaries will be managed using conventional transoral or transcervical techniques; oropharynx or hypopharynx tumor will be managed with transoral robotic surgery; and larynx tumors (T3/T4 with thyroid cartilage invasion) will be managed by either total laryngectomy or larynx preservation surgery.
