Primary Outcome Measures
NameTimeMethod
Intracranial Objective response rate(iORR)Approximately 3 years

Objective response rate according to response assessment in neuro-oncology-brain metastases (RANO-BM) criteria.

Secondary Outcome Measures
NameTimeMethod
Progression-free survival (PFS)Approximately 3 years

measured by RANO-BM and RECIST 1.1

TmaxApproximately 3 years

Intracranial Disease control rate (iDCR)Approximately 3 years

Percentage of participants with BOIR of CR, PR, or SD: IDCR, as defined by RANO-BM is reported.

Extracranial Objective response rate(eORR)Approximately 3 years

Objective response rate according to response assessment in neuro-oncology-brain metastases (RANO-BM) criteria.

Extracranial Disease control rate (eDCR)Approximately 3 years

Percentage of participants with BOIR of CR, PR, or SD: IDCR, as defined by RANO-BM is reported.

Intracranial Duration of remission (iDOR)Approximately 3 years

DoR is measured from the date of first evidence of a confirmed response (CR or PR), as defined by RANO-BM, to the date objective progression or death from any cause.
