Rational Approaches for Combination Therapy Strategies Targeting the MAP Kinase Pathway in Solid Tumors

Molecular characterization of oncogenic mutations within genes in the MAPK and PI3K/AKT/mTOR pathways has led to the rational development of targeted therapies. Combining BRAF and MEK inhibitors to target two steps in the MAPK pathway (vertical inhibition) is now standard of care in advanced-stage melanoma harboring BRAF V600 mutation. Encouraging results have been seen in several tumor types with the same mutation, including BRAF V600–mutant...
