Study Description

Brief Summary:

The primary purpose of this study is to evaluate the efficacy and safety of WX-0593 vs. crizotinib in patients with ALK-positive non-small cell lung cancer who had not received prior systemic therapy

Condition or disease	Intervention/treatment	Phase
Non-small Cell Lung Cancer	Drug: WX-0593 Tablets; Drug: crizotinib	Phase 3

Detailed Description:

To evaluate the efficacy and safety of WX-0593 vs. crizotinib in patients with ALK-positive NSCLC who had not received prior systemic therapy, to obtain additional pharmacokinetic (PK) data from sparse PK sampling, to compare the quality of life (QoL) in patients receiving WX-0593 vs. crizotinib, to evaluate the status of exploratory biomarkers and correlate with clinical outcome, and to obtain germline DNA samples for possible pharmacogenetic analysis in the event that outliers with respect to efficacy, tolerability/safety, or exposure are identified.
