This randomized phase III trial studies how well crizotinib works and compares it to placebo in treating patients with stage IB-IIIA non-small cell lung cancer that has been removed by surgery and has a mutation in a protein called ALK. Mutations, or changes, in ALK can make it very active and important for tumor cell growth and progression. Tumors with this mutation may respond to treatments that target the mutation, such as crizotinib. Crizotinib may stop the growth of tumor cells by blocking the ALK protein from working. It is not yet known if crizotinib may be an effective treatment for treating non-small cell lung cancer with an ALK fusion mutation.
I. To evaluate whether adjuvant therapy with crizotinib will result in improved overall survival (OS) over placebo for patients with stage IB >= 4 cm, II and IIIA, anaplastic lymphoma kinase (ALK)-positive non-small cell lung cancer (NSCLC) following surgical resection.
I. To evaluate and compare disease-free survival (DFS) associated with crizotinib and placebo.
II. To evaluate the safety profile of crizotinib when given in the adjuvant therapy setting.
III. To collect tumor tissue and blood specimens for future research.
OUTLINE: Patients are randomized to 1 of 2 treatment arms.
ARM A: Patients receive crizotinib orally (PO) twice daily (BID) on days 1-21. Treatment repeats every 21 days for up to 2 years in the absence of disease progression or unacceptable toxicity.
ARM B: Patients receive placebo PO BID on days 1-21. Treatment repeats every 21 days for up to 2 years in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for 2 years, every 6 months for 3 years, and then yearly for 5 years.
