Notable examples include the epidermal growth factor receptor (EGFR) inhibitors erlotinib and gefitinib for the treatment of advanced EGFR-mutated non-small cell lung cancer; the BRAF and MEK inhibitors vemurafenib and trametinib for metastatic V600-mutated melanomas; and the multi-kinase inhibitor cabozantinib for metastatic medullary thyroid cancer and renal cell carcinoma [14]. The gene discussed is EGFR; the disease is melanoma.
