  • Title: Trametinib in metastatic melanoma.
    Author: Chopra N, Nathan PD.
    Journal: Expert Rev Anticancer Ther; 2015; 15(7):749-60. PubMed ID: 26107021.
    Abstract:
    The treatment of metastatic melanoma is rapidly changing. In 2002, the BRAF mutation was described in over 50% of melanomas and led to the first BRAF inhibitor, vemurafenib, being approved for clinical use in 2011. Clinical responses are often rapid but duration of response is limited due to the development of resistance. MEK is the next downstream target from BRAF in the MAP kinase pathway. Trametinib was the first MEK inhibitor to be approved for clinical use in 2013. Preclinical studies demonstrated a delay in resistance and a reduction in cutaneous toxicity by combined BRAF and MEK inhibition. Here, we review the rationale for clinical development of trametinib and give an update on recent clinical trials of trametinib alone and in combination with braf inhibition in melanoma.
