Inclusion criteria

Inclusion criteria: - Participants must have a histologically- or cytologically-confirmed diagnoses of non-small cell lung cancer (NSCLC) with unresectable Stage III disease. - Participants must have received at least 2 cycles of platinum-based concurrent chemoradiotherapy (a total dose of radiation of at least 54 Gy). - Participants must have no progressive disease (PD) following treatment with concurrent chemoradiotherapy (CCRT). - Participants must have an Eastern Cooperative Oncology Group (ECOG) performance status (PS) score of 0 or 1.
