ETOP 15-19 ABC-lung is an international, multi-centre open-label, randomized phase II trial with two non-comparative parallel arms of atezolizumab plus bevacizumab with carboplatin-paclitaxel (Arm A) or atezolizumab, bevacizumab and pemetrexed (Arm B) in patients with stage IIIB-IV non-squamous non-small cell lung cancer (NSCLC) harbouring EGFR mutations after failure of standard EGFR tyrosine kinase inhibitors (TKIs).
