Обзор

Study to evaluate the efficacy of treatment by radiotherapy and pembrolizumab in newly diagnosed metastatic head \& neck cancers

Подробное описание

Comparative interventional prospective phase 3, randomised, open-label, multicentric trial comparing the combination of radiotherapy and pembrolizumab alone or with chemotherapy to systemic treatment as first line treatment of patients with newly diagnosed head and neck squamous cell carcinoma with synchronous metastases.

Вмешательства

• Препарат Pembrolizumab
  Pembrolizumab 200 mg every 3 weeks until disease progression (as confirmed according to response evaluation criteria in solid tumors version 1.1 (RECIST v1.1)) or unacceptable toxicity. The treatment of pembrolizumab should not be delayed because of radiotherapy planning.
• Лучевая терапия Loco-regional radiotherapy
  Depending on the choice of radiotherapy timing: * Before 3 cycles of pembrolizumab with or without chemotherapy : radiotherapy could start at any time between one week after the first administration of pembrolizumab and the first day of the 3rd cycle. * After 3 cycles of pembrolizumab with or without chemotherapy : radiotherapy could start at any time after 3rd cycle (C3D1) and up to a maximum of 4 weeks after the 6th cycle of pembrolizumab. Dose/fraction of radiotherapy: 54 Gy/18 fractions (r
• Препарат Chemotherapy
  If the investigator decide to add chemotherapy with pembrolizumab, and depending on the radiotherapy timing: * Start of radiotherapy planned before 3rd cycle: Chemotherapy could be delayed after the end of radiotherapy and start from cycle 3 or 4 of pembrolizumab. Administration of chemotherapy can be delayed in case of non resolved grade 3 or higher toxicity from radiotherapy. * Radiotherapy planned after 3rd cycle: Chemotherapy should start at the same time of pembrolizumab.
