  4. dPatients with ongoing treatment were censored for overall follow-up, duration of therapy and survival estimates. In total, 100 patients were censored due to ongoing treatment. Ongoing treatment was defined as a treatment administration between 5 May 2016 and 30 June 2016
  5. ePatients with ongoing treatment were not censored for calculations of the number of dose modifications or infusions
  6. Patients may have received ramucirumab in multiple LOTs
