Introduction: Cancer immunotherapy has revolutionized the treatment of patients with advanced or metastatic non-small cell lung cancer (NSCLC). However, specific patient groups (e.g. patients with activating epidermal growth factor receptor [EGFR] mutations) do not appear to derive benefit from immune checkpoint inhibitor (ICI) monotherapy. Combining ICIs, such as atezolizumab, with chemotherapy and/or targeted therapies may help to address this unmet need. Areas covered: Atezolizumab is an anti-programmed death-ligand 1 therapy for several tumor types. We review its clinical efficacy and safety in the treatment of advanced or metastatic NSCLC, with a specific focus on the combination of atezolizumab with bevacizumab, carboplatin, and paclitaxel (ABCP). Data from IMpower150 show that the ABCP regimen provided clinical benefit to patients with non-squamous NSCLC, including those with EGFR mutations. Expert opinion: Combining ICIs with chemotherapy has proven to be superior to chemotherapy alone. However, tumor resistance to ICIs will likely increase as these drugs enter earlier lines of therapy, underscoring a need for effective treatments when immunotherapy fails. Data suggest that the ABCP regimen may circumvent ICI resistance mechanisms. Continued investigation into the regimen's mechanisms, improved patient profiling/selection, and treatment personalization will drive further development/discoveries.
