Brief summary

The primary endpoint for ENCEFALO is the 6 month intracranial progression-free survival (icPFS), defined as the proportion of patients alive and free of icPFS according to modified RECIST criteria (Section 10.3 and Appendix 3) at 6 month evaluation (week 24 +/- 3 weeks) after the start of study treatment. The icPFS will be assessed locally by investigators.
