Eligibility criteria included: no prior chemotherapy; advanced, non-squamous, NSCLC; performance status ≤1; and epidermal growth factor receptor mutation-negative. Patients (N = 108) received induction chemotherapy with cisplatin, pemetrexed, and bevacizumab....Thirty-five patients each were randomized to the pemetrexed/bevacizumab group and the pemetrexed alone group. PFS was significantly better in the pemetrexed/bevacizumab group than in the pemetrexed alone group (7.0 vs. 5.4 months, hazard ratio: 0.56 [0.34–0.93], log-rank p = 0.023)....Addition of bevacizumab to pemetrexed as maintenance therapy prolonged PFS in patients with untreated, advanced, non-squamous NSCLC.
