BACKGROUND: Ramucirumab plus docetaxel combination therapy (DOC/RAM) for advanced non-small cell lung cancer (NSCLC) achieves favorable outcomes; however, efficacy and safety for patients with brain metastases are still unclear.
METHODS: Eligible patients included those with advanced NSCLC with measurable asymptomatic brain metastases that progressed after chemotherapy. Patients were intravenously administered ramucirumab (10 mg/kg) and docetaxel (60 mg/m2) every 21-day cycle.
RESULTS: Due to difficulties in accumulating the planned 65 participants, enrollment was terminated early when 25 patients were enrolled. Primary endpoint: Median progression-free survival (PFS) was 3.9 months (95% CI, 1.8-5.3). Secondary endpoints: Median intracranial progression-free survival was 4.6 months (95% CI, 2.5-5.9); median overall survival was 20.9 months (95% CI, 6.6-not possible to estimate); objective response rate was 20% (95% CI, 6.8-40.7); disease control rate was 68% (95% CI, 46.5-85.1). The most common grade 3 or higher toxicities were neutropenia in 10 patients (40%). Neither intracranial hemorrhage nor grade 5 adverse events were observed. Patients with higher serum soluble vascular endothelial growth factor receptor 2 concentrations at the start of treatment had slightly longer PFS.
CONCLUSION: No clinical concerns were identified with DOC/RAM for NSCLC with brain metastases in this study. Further investigation with a larger sample size is needed to determine the tolerability and safety of these populations (Trial Identifiers: University Hospital Medical Information Network in Japan [UMIN000024551] and Japan Registry of Clinical Trials [jRCTs071180048]).
