Study Summary

This is a randomized, double-blind, multi-center, global Phase II study to determine the efficacy and safety of Durvalumab plus Olaparib combination therapy compared with Durvalumab monotherapy as maintenance therapy in patients whose disease has not progressed following Standard of Care (SoC) platinum-based chemotherapy with Durvalumab as first-line treatment in patients with Stage IV non small-cell lung cancer (NSCLC) with tumors that lack activating epidermal growth factor receptor (EGFR) mutations and anaplastic lymphoma kinase (ALK) fusions.
