TRK FUSION CANCER

Look below the surface to find out what’s driving the tumor

TRK* fusion proteins are often a primary oncogenic driver across multiple tumors in adults and children1,2

  • In TRK fusion cancer, the NTRK a gene fuses with an unrelated gene, causing overexpression of the TRK protein2-4
  • NTRK gene fusions may be mutually exclusive of other known oncogenic drivers5,6
  • The presence of TRK proteins has been associated with more aggressive cancer in some tumor types, highlighting an unmet medical need among TRK fusion cancer patients7-9
The only way to find NTRK gene fusions is to test for them10
