Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Overall Response Rate [ Time Frame: Until disease progression, an average of ten months ]
    Best ORR, defined as the best response recorded from the start of the study treatment until the end of treatment.


Secondary Outcome Measures :
  1. Progression Free Survival [ Time Frame: Until disease progression, an average of ten months ]
    PFS, defined as the time from randomization to first occurrence of tumor progression based on CT-scans/MRIs.

  2. Duration of Response [ Time Frame: Until disease progression, an average of ten months ]
    The duration of response is measured from the time measurement criteria are first met for CR/PR until the first date that recurrent or progressive disease is objectively documented.
