Biomarkers Of Response And Synergistic Combinations With ERK Targeted Therapies In Human Cancers

Tech ID: 27273 / UC Case 2015-289-0


UCLA researchers have identified a set of genomic markets that identify a group of human cancer cell lines more likely to respond to ERK1/2 inhibitors. These markers are believed to be critical in identifying those patients that will most likely respond to ERK1/2 inhibition used in cancer therapy.


Extracellular signal-regulated kinase (ERK) is a kinase that activates many downstream targets through phosphorylation. The ERK-signaling pathway (also referred to as MAPK-signaling pathway) mediates various cellular responses, including cell proliferation, differentiation, growth, migration, and survival. This pathway is activated in many types of cancer. Due to the prevalence of the pathway, it is being explored for cancer therapy. However, since the pathway is found activated in so many types of tumors, there is a need to for a reliable method or diagnostic tool to identify which tumor types are most likely to respond to ERK inhibition.


  • Patient response prediction tool to ERK1/2 inhibitors
  • Based on several biomarkers identified from a comprehensive analysis of various tumor cell types treated with the inhibitors SCH77284 and BVD-523.


Diagnostic tool to:

  • Further characterize a patient’s tumor  
  • Predict the patients most likely to benefit from ERK1/2 inhibition



  • ERK1/2 targeted therapy
  • Based on the UCLA/TORL response dataset for identification of biomarkers
  • Use of biomarkers that have not been previously implicated in biological mechanisms of response to ERK inhibition
