Description

Background: In an open-label multicenter non-randomized non-comparative phase II study in patients with stage IIIB/IV non-squamous non -small cell lung cancer (NSCLC), oncogenic addiction (EGFR mutation or ALK/ROS1 fusion), with disease progression after tyrosine-kinase inhibitor and no prior chemotherapy (NCT04042558), atezolizumab, carboplatin, pemetrexed with or without bevacizumab showed some promising result. Beyond the clinical evaluation, we assessed safety and patient-reported outcomes (PROs) to provide additional information on the relative impact of adding atezolizumab to chemotherapy with and without bevacizumab in this population. Materials: Patients received platinum-pemetrexed-atezolizumab-bevacizumab (PPAB cohort) or, if not eligible, platinum-pemetrexed-atezolizumab (PPA cohort). The incidence, nature, and severity of adverse events (AEs) were assessed. PROs were evaluated using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-Core 30 and EORTC QLQ-Lung Cancer 13). Result: Overall, 68 (PPAB) and 72 (PPA) patients were evaluable for safety. Grade 3 -4 AEs occurred in 83.8% (PPAB) and 63.9% (PPA). Grade 3 -4 atezolizumab-related AEs occurred in 29.4% and 19.4%, respectively. Grade 3 -4 bevacizumab-related AEs occurred in 36.8% (PPAB). Most frequent grade 3 -4 AEs were neutropenia (19.1% in PPAB; 23.6% in PPA) and asthenia (16.2% in PPAB; 9.7% in PPA). In PPAB, we observed a global stability in global health security (GHS) score, fatigue and dyspnea with a constant tendency of improvement, and a significant improvement in cough. In PPA, we observed a significant improvement in GHS score with a significant improvement in fatigue, dyspnea and cough. At week 54, we observed an improvement from baseline in GHS score for 49.2% of patients. In both cohorts, patients reported on average no clinically significant worsening in their overall health or physical functioning scores. Conclusion: PPAB and PPA combinations seem tolerable and manageable in patients with stage IIIB/IV nonsquamous NSCLC with oncogenic addiction (EGFR mutation or ALK/ROS1 fusion) after targeted therapies.
