For inclusion in the optional biomarker research, patients must fulfil the following criteria: Provision of informed consent for biomarker research If a patient declines to participate in the optional exploratory genetic research or the optional biomarker research, there will be no penalty or loss of benefit to the patient. The patient will not be excluded from other aspects of the study.

E.5 End points |
E.5.1 | Primary end point(s) |
Progression-Free Survival at 6 months (24 weeks) (PFS-6) estimated by the RANO criteria. Progression free survival (PFS) is defined as the time from study inclusion to time of tumor progression or death due to any cause, whichever comes first. PFS-6 is the percentage of patients who have not progress 6 months after study inclusion.

|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
• Median-PFS is defined by the time in which fifty percent (50%) of patients have experienced tumor progression or death due to any cause or the date of last tumor assessment. • Overall Survival: Overall survival is defined as the time from study inclusion to death due to any cause, or to the date of censoring at the last time the subject was known to be alive in intention-to-treat populations • Overall response rate is defined by the percentage of patients with complete response and partial response using RANO criteria. The overall response rate will be assessed by the local investigators and after central radiological review that will be done at the end of the study. • Duration of response is defined by the time from confirmation of stable, partial and complete response using RANO criteria until the tumor progression has been shown. • Longitudinal changes in quality of life (EORTC QLQ-C30 and BN20) • Safety: Type, frequency and severity of adverse events and serious adverse events. The adverse events will be described and graded according to the revised NCI Common Terminology Criteria V4.03 for Adverse Events (CTCAE V4.03) at each clinical visit.
