About 20% of patients with advanced NSCLC have brain metastases, which are related to poor prognosis. However, the effect of ICI therapy combined with platinum-based chemotherapy on untreated brain metastases derived from NSCLC remains unclear. The primary endpoint of this study is intracranial response rate as determined by modified Response Evaluation Criteria in Solid Tumors (RECIST) for brain metastases of ≥ 5 mm as target lesions. Eligible patients are 20 years of age or older with chemotherapy-naïve advanced NSCLC and at least one brain metastasis ≥ 5 mm in size that has not been previously treated. Patients receive nivolumab plus ipilimumab intravenously combined with histology-based platinum doublet chemotherapy (two cycles). Individuals with known genetic driver alterations such as those affecting EGFR or ALK are excluded. Planned enrollment is 30 patients over 2.5 years at 27 oncology facilities in Japan. This is the first prospective study to focus on the intracranial response to ICI therapy combined with platinum-based chemotherapy in patients with untreated brain metastases derived from NSCLC. If the study demonstrates intracranial efficacy for this patient population, then this regimen has the potential to become a new treatment option for such individuals.Keywords: clinical trial, NSCLC, nivolumab plus ipilimumab, brain metastases, intracranial response rate
