This is a Phase III, randomized, parallel-arm, placebo controlled, double blind, multicenter study assessing the efficacy and safety of durvalumab versus placebo following SoC chemotherapy in patients with completely resected stage II-III NSCLC who are MRD+ post surgery


Patients who have no evidence of disease recurrence confirmed by CT and/or MRI and are confirmed to meet all eligibility criteria will be randomized 1:1 to durvalumab + Standard of care (SoC) chemotherapy or placebo + Standard of care (SoC) chemotherapy arm.

The primary objective of this study is to assess the efficacy of durvalumab +SoC chemotherapy compared to placebo+ SoC chemotherapy in terms of DFS measured in MRD+ patients.

Condition Carcinoma, Non-Small-Cell Lung
Treatment Durvalumab + SoC chemotherapy, Placebo + SoC chemotherapy
