Harnessing Analysis RNA Expression and Molecular Subtype to Optimize Novel TherapY MBCA
The HARMONY trial is an interventional trial enrolling metastatic breast cancer (MBC). Current treatment of breast cancer uses clinical subtype information (e.g. hormone receptor-positive (HR+)) to help guide treatment options. Breast cancer can also be characterized by molecular subtype, but it is not known if this information is helpful in determining treatment when breast cancer has become metastatic. HARMONY will give the treating physician of each participant the molecular subtype of the tumor based on PAM50 testing. The usefulness of this information will be determined through the physic
