- Time to local progression - TTLP [ Time Frame: 12 months ]
Local progression will be defined according to the RANO-BM criteria by an increase of at least 20% in the longest diameter of the metastasis relative to nadir or baseline. In addition to the relative increase of 20% the lesion must increase by an absolute value of 5 mm or more.
TTLP is defined as the time from randomization until the detection of progression as per the RANO-BM criteria. Patients will be censored if they have no signs of local progression at the time of last tumor monitoring during follow-up or at the onset of one of the following competing risk events not associated with local progression: death, lost to follow up, unauthorized non-protocol treatment of the target lesion.
Confirmatory analysis of the primary endpoint variable will be performed using a p-value of p≤0.05 as the global significance level.
- CNS toxicity according to CTCAE v5.0 [ Time Frame: 12 months ]CNS toxicity according to CTCAE v5.0
- Time to local progression (Volumetric RANO-BM criteria) [ Time Frame: 12 months ]Based on the RANO-BM criteria, progression is defined as an increase in volume of 72.8% or more (corresponds to a 20% increase in diameter for a perfect sphere).
- Quality of Life according to EORTC QLQ-C30 [ Time Frame: Change from baseline to 3, 6, 12 and 24 months ]Quality of life measured by European Organization for Research and Treatment of Cancer (EORTC) questionnaire QLQ C30
- Local-Progression-Free Survival [ Time Frame: 12 months ]Local-Progression-Free Survival is defined like TTLP except that death not associated with local progression will not be censored but assessed as a separate event
- Overall Survival [ Time Frame: 24 months ]Overall Survival
- Quality of Life according to EORTC QLQ-BN20 [ Time Frame: Change from baseline to 3, 6, 12 and 24 months ]Quality of life measured by European Organization for Research and Treatment of Cancer (EORTC) questionnaire QLQ BN20
