简要总结
The purpose of this study is to evaluate the efficacy and safety of Afatinib in maintenance therapy after post-operative radiochemotherapy (66 Gy and Cisplatin at the dose of 100mg/m2 every 3 weeks)in squamous cell carcinoma of the head and neck.
详细描述
The reference treatment for operated squamous cell carcinoma of the head and the neck is a radiochemotherapy with Cisplatin (in the dose of intravenous 100 mg / m2 IV) every 3 weeks).
The Receptor of EGFR (Epidermal Growth Factor) or REGF is a membrane receptor; it's activation leads the cellular growth and inhibits apoptotic capacities. This receptor is overexpressed in numerous solid tumors, including ENT tumors. Several clinical studies showed that an over expression of the REGF in ENT tumors was a dominant factor of poor prognostic.
Afatinib (BIBW2992) is a strong and irreversible inhibitor of the EGFR ( type 1 human epidermic growth factor receptor, also known as HER1) and of the HER2 (human epidermal growth factor receptor 2).
Currently, 3 phase III clinical studies in postoperative situation and using an anti-REGF are in progress: 2 in concomitant situation with the radiotherapy and 1 both in concomitance and in adjuvant therapy with radiotherapy.
The preliminary results of a phase II study show that Afatinib is efficient in patients with local or metastatic relapse of a squamous cell carcinoma of the sphere ENT after a first line with Cisplatin and its tolerance is correct.
