- 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.
- 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.
- 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.
