Key Inclusion Criteria

Age ≥18 years
Complete resection of histologically confirmed Stage IB (tumor ≥ 4 cm) to Stage IIIA (T2-3 N0, T1-3 N1, T1-3 N2, T4 N0-1) NSCLC as per Union Internationale Contre le Cancer / American Joint Committee on Cancer, 7th edition, with negative margins, at 4-12 weeks before enrollment
If mediastinoscopy was not performed preoperatively, it is expected that, at a minimum, mediastinal lymph node systematic sampling will have occurred
Documented ALK-positive disease according to an FDA-approved and CE-marked test
Eligible to receive a platinum-based chemotherapy regimen according to the local labels or guidelines
Eastern Cooperative Oncology Group Performance Status of Grade 0 or 1
Adequate hematologic and renal function
For women of childbearing potential: agreement to remain abstinent or use contraceptive methods with a failure rate of < 1% per year during the treatment period and for at least 90 days after the last dose of alectinib or according to local labels or guidelines for chemotherapy
For men: agreement to remain abstinent or use contraceptive measures, and agreement to refrain from donating sperm for at least 90 days after the last dose of alectinib or according to local labels or guidelines for chemotherapy. Men must refrain from donating sperm during this same period

Key Exclusion Criteria

Pregnant or breastfeeding, or intending to become pregnant during the study or within 90 days after the last dose of alectinib or according to local labels or guidelines for chemotherapy
Prior adjuvant radiotherapy for NSCLC
Prior exposure to systemic anti-cancer therapy and ALK inhibitors
Stage IIIA N2 patients that, in the investigator's opinion, should receive post-operative radiotherapy treatment are excluded from the study
Known sensitivity to any component of study drug to which the patient may be randomized. This includes, but is not limited to, patients with galactose intolerance, a congenital lactase deficiency or glucose-galactose malabsorption.
Malignancies other than NSCLC within 5 years prior to enrollment, except for curatively treated basal cell carcinoma of the skin, early gastrointestinal (GI) cancer by endoscopic resection, in situ carcinoma of the cervix, ductal carcinoma in situ, papillary thyroid cancer, or any cured cancer that is considered to have no impact on disease free survival or overall survival for the current NSCLC
Any GI disorder that may affect absorption of oral medications, such as malabsorption syndrome or status post-major bowel resection
Liver disease characterized by aspartate transaminase and alanine transaminase >= 3 × upper limit of normal or impaired excretory function or synthetic function or other conditions of decompensated liver disease such as coagulopathy, hepatic encephalopathy, hypoalbuminemia, ascites, or bleeding from esophageal varices or active viral or active autoimmune, alcoholic, or other types of acute hepatitis
Japanese patients participating in the serial/intensive PK sample collection only: administration of strong/potent CYP450 3A inhibitors or inducers within 14 days prior to the first dose of study treatment and while on treatment with alectinib up to Week 3
Any exclusion criteria based on the local labels or guidelines for chemotherapy regimen
Patients with symptomatic bradycardia
History of organ transplant
Known HIV positivity or AIDS-related illness
Any clinically significant concomitant disease or condition 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 pose an unacceptable risk to the patients in this study, in the opinion of the Principal Investigator
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 patient before trial entry
