Summary:

      This is a multicenter, worldwide, open-label study of MK-8353 in combination with selumetinib
      in participants with histologically or cytologically confirmed diagnosis of advanced solid
      tumor. This study will evaluate the safety, tolerability, and exploratory efficacy of MK-8353
      in combination with selumetinib.
