To evaluate clinical performance of IOpener-melanoma in patients where standard of care treatment selection is based on IOpener-melanoma test result

Secondary objectives 2

  1. to evaluate clinical predictive performance (sensitivity, specificity, PPV, NPV) of IOpener-melanoma test for DCR, ORR, PFS and OS
  2. To establish clinical utility of IOpener-melanoma test by performing health economic impact analysis
