Sorafenib/Erlotinib Versus Erlotinib Alone in Previously Treated Advanced Non-Small-Cell Lung Cancer (NSCLC)

The rationale of this study is to combine two distinct kinase inhibitors to evaluate synergistic inhibition of angiogenesis and epidermal growth factor receptor (EGFR) signaling. Erlotinib is a oral tyrosine kinase inhibitor that targets EGFR. Sorafenib is a oral tyrosine kinase inhibitor targeting vascular endothelial growth factor receptor (VEGFR), platelet derived growth factor receptor beta, Raf-1, Flt-3, and C-kit. These agents also do not exhibit overlapping adverse event profiles which provided additional support for studying this combination therapy.
