INTRODUCTION: LUN17-139 evaluated the safety and efficacy of Atezolizumab (A) plus Carboplatin (C) plus Pemetrexed (Pem) plus Bevacizumab (B) (ACBPem) in treatment naïve patients with stage IV non-squamous non-small cell lung cancer (Ns-NSCLC).
PATIENTS AND METHODS: In this multicenter, single-arm phase II trial, all patients received A (1200-mg, D1) + C (AUC 5, D1) + Pem (500-mg/m2, D1) + B (15-mg/kg D1) q3 week x4. If no PD (progressive disease), patients received maintenance ABPem until PD or intolerable side effects. The primary endpoint was progression-free survival (PFS). The positive PFS result was considered as PFS>6m (historical control). Secondary endpoints included objective response rate (ORR), disease control rate (DCR) defined by complete response (CR) + partial response (PR) + stable disease (SD) ≥ 2 months, overall survival (OS), and safety.
RESULTS: Thirty patients were enrolled from November 2018 to October 2020. The study was closed early due to 3 patient deaths, possibly related to treatment. Median age 64 (range 38-83); Men/Women 20/10; PD-L1 TPS < 1%/1-49%/ ≥ 50% (8/15/7). The median follow-up was 20.3 months ( 1-28.1). ORR 42.9% (95% CI, 24.5-62.8%), DCR 96.4% (95% CI, 81.7-99.9%). The median PFS and OS were 11.3m (5.5-14.9,P > .05) and 22.4m (22.4-NR), respectively. Four patients had G4 toxicity (anemia, febrile-neutropenia, severe neutropenia, sepsis), and 3 patients had G5 toxicity (thromboembolism, sepsis, colonic perforation).
CONCLUSION: ABCPem was associated with increased PFS compared to historical controls but this difference did not meet the statistical significance. Three on-treatment deaths and 5 thromboembolic events prompted early closure.
