Intracranial Objective Response (iORR) by Modified RECIST 1.1 Before Local Radiotherapy Treatment in Full Dataset Primary · 24 months after start of treatment

iORR calculated as the proportion of patient with a best overall intracranial response of complete response (CR) or partial response (PR) before local treatment according to modified RECIST 1.1. Modified RECIST 1.1 consists of: Up to 5 intracranial lesions could be selected as target lesions Target lesions might have a longest diameter ≥ 5 mm when evaluated by contrast-enhanced MRI This endpoint was also independently reported in patients with symptomatic and asymptomatic brain metastasis.

Duration of Intracranial Response Secondary · Throughout the study period, up to approximately 24 months

Intracranial Progression-free Survival (iPFS) by RECIST 1.1 Secondary · Throughout the study period, up to approximately 24 months

Defined as the time from the date of inclusion to the date of the first documented intracranial disease progression or death due to any cause, whichever occurs first. PFS was determined based on tumor assessment (modified RECIST version 1.1 criteria). The local Investigator's assessments was used for analyses. Those patients who were alive and had not progressed at the last follow-up, date of progression was censored at the date of the last follow-up.

Change on Quality of Life at Week 8 in Both Cohorts Based on the EORTC QLQ 30 Scale Secondary · 8 weeks

The EORTC QLQ-C30 questionnaire is validated for cancer. It is composed of 30 questions or items that assess QoL. The questionnaire is structured in 5 functional scales physical functioning, daily activities, emotional functioning, cognitive functioning and social functioning), 3 symptom scales (fatigue, pain and nausea, vomiting), 1 global health status scale, and 6 independent items (dyspnea, insomnia, anorexia, constipation, diarrhea and economic impact). Values between 1 and 4 (1: not at all, 2: a little, 3: quite, 4: a lot) are assigned according to the patient's responses to the item, on
