Wednesday, April 08, 2020 The CCTG BR31 (NCT02273375) trial, A Phase III Prospective Double Blind Placebo Controlled Randomized Study of Adjuvant MEDI4736 in Completely Resected Non-Small Cell Lung Cancer has been closed to accrual to the main study. The purpose of this study was to find out whether it is better to receive a new drug, MEDI4736, or better to receive no further treatment after surgery (and possibly chemotherapy) for lung cancer. Primary Objective: Disease free survival (DFS) for patients with NSCLC that is PD-L1 positive. Disease free survival (DFS) in all randomized patients. Secondary Objectives: Overall survival (OS) for patients with NSCLC that is PD-L1 positive, OS for all randomized patients, lung cancer specific survival for patients with NSCLC that is PD-L1 positive and all randomized patients, adverse effects and tolerability of MEDI4736, Quality of Life, survival benefits participants judge necessary to make adjuvant immunotherapy worthwhile, economic evaluation (cost effectiveness and cost utility), evaluation of predictive/prognostic significance of PD-L1 expression, evaluation of changes in plasma/serum cytokines and other blood and tissue based biomarkers after treatment with MEDI4736 and at disease event, exploratory pharmacogenomic assays (baseline only).
