Description
GDC-0994 is an inhibitor of ERK1/2, which is commonly activated by oncogenic mutations in B-Raf or Ras. It is effective against cancer cell lines that are resistant to B-Raf and MEK1/2 inhibitor therapy. Combination therapy targeting multiple nodes of the Ras/Raf/MEK/ERK signaling cascade enhances efficacy and diminishes the potential for acquired drug resistance.
