      Bevacizumab (BEV) combined with platinum-based chemotherapy is a standard treatment for advanced non-squamous non-small-cell lung cancer (non-Sq NSCLC). Cisplatin (CDDP) + pemetrexed (PEM) is suggested as the most promising chemotherapy regimen combined with BEV. However, no study has been conducted to evaluate the efficacy and safety of CDDP+PEM+BEV compared with carboplatin (CBDCA) + paclitaxel (PTX) + BEV for advanced non-Sq NSCLC.

      Treatment-naïve patients with advanced or recurrent EGFR/ALK-negative non-Sq NSCLC from 55 sites across Japan were randomly assigned in a 2:1 ratio to either CDDP+PEM+BEV (4 cycles of CDDP [75 mg/m2] + PEM [500 mg/m2] + BEV [15 mg/kg] q3wk, followed by maintenance PEM + BEV q3wk until progression) or CBDCA+PTX+BEV (4 cycles of CBDCA [AUC 6] + PTX [200 mg/m2] + BEV q3wk, followed by maintenance BEV q3wk until progression). The primary endpoint was progression-free survival (PFS) by central review. The secondary endpoints were PFS by investigators, overall survival (OS), overall response rate (ORR) and safety profile. The target numbers of patients and events were determined to be 210 and 170, respectively, to observe a point estimate of HR for PFS (CDDP+PEM+BEV/CBDCA+PTX+BEV) <0.83 with a high probability (80%) when the true HR was 0.72.

      Between May 2014 and May 2016, 199 patients were randomly assigned to receive CDDP+PEM+BEV (N=132) or CBDCA+PTX+BEV (N=67). The median follow-up duration was 20.6 months. PFS events occurred in 171 patients. The HR for PFS by central review (CDDP+PEM+BEV/CBDCA+PTX+BEV) was 0.825 (95% CI 0.600-1.134, median PFS, 7.6 vs 7.0 months). The median PFS by investigators was longer with CDDP+PEM+BEV than with CBDCA+PTX+BEV (HR 0.634, 95% CI 0.464-0.867, median PFS, 7.4 vs 6.8 months). The median OS was 24.5 months for CDDP+PEM+BEV and 23.6 months for CBDCA+PTX+BEV (HR 0.955, 95% CI 0.620-1.470). The ORR was 57% for CDDP+PEM+BEV and 55% for CBDCA+PTX+BEV. The most common ≥G3 adverse events in both arms (CDDP+PEM+BEV/CBDCA+PTX+BEV) were neutropenia (24%/64%), hyponatraemia (11%/9%) and hypertension (30%/23%).

      CDDP+PEM is the most effective chemotherapy regimen combined with BEV for advanced non-Sq NSCLC.
