Durvalumab With or Without Tremelimumab in Resectable Locally Advanced Squamous Cell Carcinoma of the Oral Cavity

UnknownPhase 1, Phase 2

Sponsor: Universitaire Ziekenhuizen KU Leuven

Conditions: Oral Cavity Squamous Cell Carcinoma

Interventions: Durvalumab, Durvalumab + Tremelimumab

Countries: Belgium

This is a randomized, open-label, prospective, pilot phase I/II study with focus on translational research and on the evaluation of the biological changes that are observed in sequential tumor tissue acquisition in patients with newly diagnosed advanced (stage IV) oral cavity SCC. Patients are treated with Durvalumab (arm A) or Durvalumab + Tremelimumab (arm B) after biopsy-confirmed diagnosis of locally advanced resectable SCCHN of the oral cavity. After surgery, the standard of care treatment is radiotherapy, and, depending on risk assessment concurrent cisplatin. Patients will be treated with Durvalumab (arm A) or Durvalumab and Tremelimumab (arm B) during six additional cycles, starting from day one of the postoperative radiotherapy.
