BACKGROUND: The effect of dual immunotherapy combined with platinum-based chemotherapy on untreated brain metastases derived from non-small cell lung cancer (NSCLC) has remained unclear.
METHODS: This multicenter single-arm phase 2 study enrolled patients with chemotherapy-naïve advanced NSCLC and at least one brain metastasis ≥ 5 mm in size that had not been previously treated. Patients received nivolumab plus ipilimumab combined with platinum-doublet chemotherapy (two cycles), followed by nivolumab-ipilimumab alone. The primary endpoint of the study was intracranial response rate as determined by modified Response Evaluation Criteria in Solid Tumors (RECIST) for brain metastases of ≥ 5 mm as target lesions.
RESULTS: A total of 30 patients from 18 institutions was enrolled in this study. The median age was 66.5 years (range, 47-83 years), and 26 patients (87 %) had a non-squamous cell carcinoma histology. The median size of all target brain lesions was 8.4 mm, with a range of 5-39 mm. The intracranial response rate assessed by modified RECIST was 50.0 % (95 % CI, 33.2-66.8 %), with the rate of complete response being 20.0 %, and the study met its primary endpoint. The systemic response rate was 53.3 % (95 % CI, 36.1-69.8 %), and responses for intracranial and extracranial lesions were generally consistent. The median intracranial progression-free survival was 8.1 months, and both the median intracranial duration of response and time to brain radiotherapy were not reached.
CONCLUSION: Nivolumab plus ipilimumab combined with platinum-based chemotherapy showed promising intracranial activity in NSCLC patients with untreated brain metastases.
