Alectinib Versus Pemetrexed or Docetaxel in Anaplastic Lymphoma Kinase (ALK)-Positive Advanced Non-Small Cell Lung Cancer (NSCLC) Participants Previously Treated With Platinum-Based Chemotherapy and Crizotinib

Randomized, Multicenter, Phase III, Open-Label Study of Alectinib Versus Pemetrexed or Docetaxel in Anaplastic Lymphoma Kinase-Positive Advanced Non Small Cell Lung Cancer Patients Previously Treated With Platinum-Based Chemotherapy and Crizotinib

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).

Inclusion Criteria:

• Histologically or cytologically confirmed diagnosis of advanced or recurrent (Stage IIIB not amenable for multimodality treatment) or metastatic (Stage IV) NSCLC that is ALK-positive. ALK positivity must have been determined by a validated fluorescence in situ hybridization (FISH) test (recommended probe, Vysis ALK Break-Apart Probe) or a validated immunohistochemistry (IHC) test (recommended antibody, clone D5F3)
• Participant had received two prior systemic lines of therapy, which must have included one line of platinum-based chemotherapy and one line of crizotinib
• Prior CNS or leptomeningeal metastases allowed if asymptomatic
• Participants with symptomatic CNS metastases for whom radiotherapy is not an option will be allowed to participate in this study
• Measurable disease by RECIST Version 1.1 prior to the administration of study treatment
• Eastern Cooperative Oncology Group (ECOG) performance status of 0-2
• For all females of childbearing potential, a negative pregnancy test must be obtained within 3 days before starting study treatment

Exclusion Criteria:

• Participants with a previous malignancy within the past 3 years are excluded (other than curatively treated basal cell carcinoma of the skin, early gastrointestinal [GI] cancer by endoscopic resection or in situ carcinoma of the cervix)
• Participants who have received any previous ALK inhibitor other than crizotinib
• Any GI disorder that may affect absorption of oral medications
