Inclusion Criteria

Participant must be ≥ 18 years at the time of screening
Histologically- or cytologically-documented NSCLC and have been treated with concurrent CRT for locally advanced, unresectable (Stage III) disease
Provision of a tumour tissue sample obtained prior to CRT
Documented tumour PD-L1 status by central lab
Documented EGFR and ALK wild-type status (local or central)
Patients must not have progressed following definitive, platinum based, concurrent chemoradiotherapy
Participants must have received at least 2 cycles of platinum-based chemotherapy concurrent with radiation therapy
Participants must have received a total dose of radiation of 60 Gy ±10% (54 Gy to 66 Gy) as part of the chemoradiation therapy, to be randomised. Radiation therapy should be administered by intensity modulated RT (preferred) or 3D-conforming technique

Mixed small cell and non-small cell lung cancer histology
Participants who receive sequential (not inclusive of induction) chemoradiation therapy for locally advanced (Stage III) unresectable NSCLC
Participants with locally advanced (Stage III) unresectable NSCLC who have progressed during platinum-based cCRT
Any unresolved toxicity CTCAE >Grade 2 from the prior chemoradiation therapy (excluding alopecia)
Participants with ≥grade 2 pneumonitis from prior chemoradiation therapy
History of idiopathic pulmonary fibrosis, organizing pneumonia, drug induced pneumonitis, or idiopathic pneumonitis, or evidence of active pneumonitis, ILD, pleural effusion, or pulmonary fibrosis diagnosed in the past 6 months prior to randomization
Active or prior documented autoimmune or inflammatory disorders (with exceptions)
