Summary

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.

Detailed description

Durvalumab has shown activity in squamous cell carcinoma of the head and neck. Locally advanced resectable cancers of this type represent a challenge, as the majority of these patients still die from this disease in spite of surgery, radio- and chemotherapy. Checkpoint inhibitors have recently proven to prolong life in recurrent/metastatic SCCHN, and several new molecules are currently tested in clinical trials in this indication, including PD-1, PD-L1, and CTLA-4 antibodies, either as single agent or in combination. These compounds might represent a valuable treatment for SCCHN patients in the adjuvant setting, given the favorable toxicity profile. Combination of Durvalumab (PD-L1 inhibition) and Tremelimumab (CTLA-4 inhibition) is currently tested in recurrent/metastatic head and neck cancer, and compared to Durvalumab as single agent, and to standard of care chemotherapy. In this study both options, i.e. durvalumab as a single agent or Durvalumab in combination with Tremelimumab, will be tested in a randomized fashion. Randomization would be used to reduce selection bias, in a non-comparative study. Newly diagnosed patients with SCCHN of the oral cavity, will be treated with a single dose of Durvalumab with or without Tremelimumab two weeks before scheduled surgery. When patients are first diagnosed with a resectable oral SCC, a biopsy is taken to confirm the diagnosis, and surgery is planned. This standard practice thus involves sequential tissue harvesting, both at the time of biopsy as well as the final resection specimen, making it possible to observe hallmarks of immune response when patients are treated once with Durvalumab with or without Tremelimumab after confirmation of the diagnosis on biopsy, but before surgery.

Conditions

• Oral Cavity Squamous Cell Carcinoma

Interventions

Type	Name	Description
DRUG	Durvalumab	All patients will be treated with postoperative radiotherapy (66 Gy in standard fractionation). In case of positive section margins or extracapsular extension, 3 cycles of cisplatin 100 mg/msq on days 1, 22, and 43 will be added to standard fractionation radiotherapy (66 Gy). Durvalumab monotherapy (1500 mg) will be administered via IV infusion day -14 and at the start of radiation therapy, with repeat administration every 4 weeks at fixed dose for a total of 6 cycles postoperative.
COMBINATION_PRODUCT	Durvalumab + Tremelimumab	All patients will be treated with postoperative radiotherapy (66 Gy in standard fractionation). In case of positive section margins or extracapsular extension, 3 cycles of cisplatin 100 mg/msq on days 1, 22, and 43 will be added to standard fractionation radiotherapy (66 Gy). Durvalumab + Tremelimumab combination therapy: Tremelimumab (75 mg) will be administered via IV infusion day -14 and at the start of radiation therapy, with repeat administration every 4 weeks at fixed dose for a total of 3 cycles postoperative, Durvalumab (1500 mg) will be administered via IV infusion day -14 and at the start of radiation therapy, with repeat administration every 4 weeks at fixed dose for a total of 6 cycles postoperative.
