Summary
Brief summary
This is a Phase III, randomized, placebo-controlled, double-blind, multi-center study assessing the efficacy and safety of durvalumab with SoC SBRT versus placebo with SoC SBRT in patients with unresected clinical Stage I/II lymph node-negative (T1 to T3N0M0) NSCLC.

An additional cohort will assess Osimertinib following SBRT in patients with early stage unresected T1 to T3N0M0 NSCLC harbouring an EGFR mutation.
