简要总结
The purpose of this study is to identify predictive and pharmacodynamic biomarkers of activity and efficacy of pre-operative Afatinib (BIBW2992) in untreated non-metastatic head and neck squamous cell carcinoma patients
详细描述
More than 500,000 new patients with squamous cell carcinomas of the head and neck (SCCHN) are diagnosed each year around the world. Patients who relapse after primary therapy for locoregional disease and those who present with distant metastases have limited prognosis.
Drug therapy for cancer control and the palliation of patients with recurrent or metastatic SCCHN is currently suboptimal. In contemporary trials the most active cytotoxic drug combinations have response rates in the range of 30%, and are associated with frequent and severe toxicities and treatment-related mortality.
Molecular targeting has been demonstrated in oncology as a relevant strategy in cancer therapeutics. In March 2006, the FDA announced the approval of a chimeric monoclonal antibody against the epidermal growth factor receptor (EGFR), cetuximab, for use in combination with radiation therapy in patients with locally advanced SCCHN. Furthermore, the addition of cetuximab to cisplatin and 5FU as first-line therapy in patients with recurrent or metastatic SCCHN has significantly improved overall survival when compared to cisplatin and 5FU alone. Phase II data of cetuximab given as monotherapy in recurrent or metastatic SCCHN patients who have progressed on platinum-based therapy have demonstrated an overall response rate of 13% and a median survival of about 6 months. Small molecules tyrosine kinase inhibitors of EGFR, such as gefitinib and erlotinib, seem to be slightly less effective than cetuximab. Based on these results, FDA has also approved cetuximab monotherapy use for this indication in recurrent or metastatic SCCHN.
However, despite high expression of EGFR in SCCHN, EGFR inhibitor monotherapy has only had modest activity. Potential mechanisms of resistance to EGFR-targeted therapies involve EGFR and K-Ras mutations, epithelial-mesenchymal transition, and activation of alternative and downstream pathways. Strategies to optimize EGFR-targeted therapy in head and neck cancer involve the selection for patients most likely to benefit and the use of therapies to target the network of pathways involved in tumor growth, invasion, angiogenesis, and metastasis.
Afatinib is an irreversible dual inhibitor of EGFR and HER2 tyrosine kinase. Preclinical data suggest that Afatinib might have a larger spectrum antitumor activity than EGFR tyrosine kinase inhibitors. In vivo and in vitro studies indeed showed that Afatinib displays antitumor activity in erlotinib/gefitinib-resistant lung models. Afatinib compared favourably to cetuximab in platinum-resistant metastatic SCCHN. In addition, Afatinib has shown promising antitumor activity in HER2-overexpressing metastatic breast cancer after trastuzumab failure and in metastatic adenocarcinomas of the lung harbouring EGFR activating mutations.
