Durvalumab for the treatment of non-small cell lung cancer

Abstract

Introduction: The prognosis of patients with advanced non-small cell lung cancer (NSCLC) remains poor, with a 5-year overall survival rate of around 15%. Immune checkpoint inhibitors, such as programmed cell death protein 1 and programmed death-ligand 1 (PD-L1) inhibitors, have opened a new era in the management of NSCLC. Three checkpoint inhibitors (nivolumab, pembrolizumab, and atezolizumab) are currently approved by the US Food and Drug Administration (FDA) for advanced NSCLC. Durvalumab, an anti-PD-L1 antibody, is under investigation in several trials.Areas covered: This article reviews the pharmacological properties, clinical efficacy, and safety of durvalumab as monotherapy and in combination with other drugs for the treatment of locally advanced and advanced NSCLC.Expert opinion: Durvalumab as monotherapy or in combination with tremelimumab was effective with well-tolerated safety profiles for advanced NSCLC in several phase I or II studies. The PACIFIC study assessed the effectiveness of durvalumab as maintenance therapy following definitive chemoradiotherapy for unresectable stage III NSCLC, and met its primary endpoints of progression-free survival and overall survival. These results led to FDA approval for this NSCLC population. It will be exciting to follow ongoing phase III studies assessing how durvalumab fits into the rapidly evolving therapeutic landscape for advanced NSCLC.
