- Progression-free survival (PFS) based on blinded independent central review (BICR) assessment [ Time Frame: From time of Study Start up to 33 months ]PFS is defined as the time from randomization to the date of the first documentation of objective progression of disease or death due to any cause, whichever occurs first.
- Overall Survival (OS) [ Time Frame: From time of Study Start up to 125 months ]OS is defined as time from date of randomization to date of death due to any cause
- PFS based on Investigator's assessment [ Time Frame: From time of Study Start up to 33 months ]PFS is defined as the time from randomization to the date of the first documentation of objective progression of disease or death due to any cause, whichever occurs first.
- Objective Response (OR) based on BICR and on Investigator's assessments [ Time Frame: From time of Study Start up to 33 months ]OR defined as complete response (CR) or partial response (PR) per RECIST version 1.1 recorded from randomization until disease progression or start of new anti-cancer therapy
- Intracranial Objective Response (IC-OR) based on BICR assessment [ Time Frame: From time of Study Start up to 33 months ]IC-OR defined as complete response (CR) or partial response (PR) based on intracranial disease in the subset of patients with at least 1 intracranial lesion per RECIST version 1.1 (modified) recorded from randomization until disease progression or start of new anti-cancer therapy
- Intracranial Time to Progression (IC-TTP) based on BIRC assessment [ Time Frame: From time of Study Start up to 33 months ]IC-TTP defined as the time from randomization to the date of the first documentation of objective progression of intracranial disease, based on either new brain metastases or progression of existing brain metastases
- Duration of Response (DR) based on BIRC assessment [ Time Frame: From time of Study Start up to 33 months ]DR defined, for patients with an OR per RECIST version 1.1, as the time from the first documentation of objective tumor response (CR or PR) to the first documentation of objective tumor progression or death due to any cause, whichever occurs first
- intracranial Duration of Response (IC-DR) based on BICR assessment [ Time Frame: From time of Study Start up to 33 months ]IC-DR defined, for patients with an IC-BOR of CR or PR, as the time from the first documentation of intracranial objective response (CR or PR) per RECIST 1.1 to the date of first documentation of intracranial objective progression of disease (PD) or death due to any cause.
- Time to Tumor Response (TTR) based on BIRC assessment [ Time Frame: From time of Study Start up to 33 months ]TTR defined, for patients with a confirmed OR, as the time from the date of randomization to the first documentation of objective response (CR or PR) which is subsequently confirmed
- Intracranial Time to Tumor Response (IC-TTR) based on BICR assessment [ Time Frame: from time of Study Start up to 33 months ]IC-TTR is defined, for patients with a confirmed IC-OR, as the time from the date of randomization to the first documentation of intracranial objective response (CR or PR) which is subsequently confirmed.
- PFS2 based on investigator's assessment [ Time Frame: From time of Study Start up to 45 months ]PFS2 is defined as the time from randomization to the date of progression of disease on first subsequent systemic anti-cancer therapy, or death from any cause, whichever occurs first
- Adverse Event (AE) as graded by NCI CTCAE v 4.03) [ Time Frame: From time of Study Start up to 33 months ]Frequency of patients experiencing treatment-emergent AEs (TEAEs)
- Laboratory abnormalities as graded by NCI CTCAE v 4.03) [ Time Frame: From time of Study Start up to 33 months ]Frequency of patients with laboratory test abnormalities
