A Study Evaluating the Efficacy and Safety of Adjuvant Platinum-Doublet Chemotherapy, With or Without Atezolizumab, in Patients Who Are ctDNA Positive After Complete Surgical Resection of Stage IB to Select IIIB Non-Small Cell Lung Cancer

NCT04611776

Description:

This is a Phase II, multicenter, double-blind, randomized study designed to evaluate the efficacy and safety of adjuvant treatment with atezolizumab in combination with platinum-doublet chemotherapy followed by atezolizumab compared with adjuvant placebo in combination with platinum-doublet chemotherapy followed by placebo in patients with Stage IB to IIIB (T3N2) NSCLC following surgical resection who are positive for ctDNA.
