Conditions: Non-small Cell Lung Cancer

Interventions: Drug: Alectinib
Drug: Docetaxel
Drug: Pemetrexed

Brief Summary: This randomized active-controlled multicenter Phase III open-label study will evaluate and compare between treatment groups the efficacy of alectinib versus chemotherapy in participants with ALK-positive advanced NSCLC who were previously treated with chemotherapy and crizotinib, as measured by investigator-assessed progression-free survival (PFS) and to evaluate and compare between treatment groups the central nervous system (CNS) objective response rate (C-ORR) in participants with measurable CNS metastases at baseline, as assessed by an Independent Review Committee (IRC).

As per RECIST v1.1, disease progression is a 20% increase in the sum of the diameters of target lesions, an increase in size of measurable lesions by at least 5 millimeter (mm) and the appearance of new lesions.
