Brief Summary
This randomized, active controlled, multicenter phase III open-label study is designed to evaluate the efficacy and safety of alectinib compared with crizotinib treatment in participants with treatment-naive anaplastic lymphoma kinase-positive (ALK-positive) advanced non-small cell lung cancer (NSCLC). Participants will be randomized in a 1:1 ratio to receive either alectinib, 600 milligrams (mg) orally twice daily (BID), or crizotinib, 250 mg orally BID. Participants will receive treatment until disease progression, unacceptable toxicity, withdrawal of consent, or death. The study is expected to last approximately 144 months.

Outcome Measures
Primary Outcomes (2)
Progression-Free Survival (PFS) by Investigator Assessment
PFS was assessed as time to disease progression or death whichever occurred first by investigator assessment using Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 (v1.1) Criteria. 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.
Randomization to first documented disease progression or death, whichever occurs first (assessed every 8 weeks up to 33 months)
Percentage of Participants With PFS Event by Investigator Assessment
PFS was assessed percentage of participants with disease progression or death whichever occurred first by investigator assessment using Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1 (v1.1) Criteria. 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.
Randomization to first documented disease progression or death, whichever occurs first (assessed every 8 weeks up to 33 months)
Secondary Outcomes (26)
PFS Independent Review Committee (IRC)-Assessed
Randomization to first documented disease progression or death, whichever occurs first (assessed every 8 weeks up to 33 months)
Percentage of Participants With PFS Event by IRC
Randomization to first documented disease progression or death, whichever occurs first (assessed every 8 weeks up to 33 months)
Percentage of Participants With Central Nervous System (CNS) Progression as Determined by IRC Using RECIST V1.1 Criteria

Percentage of Participants With Central Nervous System (CNS) Progression as Determined by IRC Using Revised Assessment in Neuro Oncology (RANO) Criteria
Randomization to the first occurrence of disease progression in the CNS (assessed every 8 weeks up to 33 months)

- Prior brain or leptomeningeal metastases allowed if asymptomatic (e.g., diagnosed incidentally at study baseline)
- Negative pregnancy test for all females of child bearing potential
- Use of highly effective contraception as defined by the study protocol
You may not qualify if:
- Participants with a previous malignancy within the past 3 years

- History of organ transplant
- Co-administration of anti-cancer therapies other than those administered in this study
- Participants with baseline QTc greater than (\>) 470 milliseconds or symptomatic bradycardia
- Recipient of strong/potent cytochrome P4503A inhibitors or inducers within 14 days prior to the first dose until the end of study treatment
- Recipient of any drug with potential QT interval prolonging effects within 14 days prior to the first dose for all participants and while on treatment through the end of the study for crizotinib-treated participants only
- History of hypersensitivity to any of the additives in the alectinib and crizotinib drug formulation
- Pregnancy or lactation
- Any clinically significant disease or condition (or history of) that could interfere with, or for which the treatment might interfere with, the conduct of the study or the absorption of oral medications or that would, in the opinion of the principal investigator, pose an unacceptable risk to the participant in this study
- Any psychological, familial, sociological, or geographical condition potentially hampering compliance with the study protocol requirements and/or follow-up procedures; those conditions should be discussed with the participant before trial entry
