Brief summary
The purpose of this retrospective study is to learn about the real-world effects of the study medicine lorlatinib for the first-line treatment of Chinese adult patients who were diagnosed with ALK-positive a/mNSCLC. The participants included in this study are: * Aged 18 years or more * diagnosed with a/mNSCLC * confirmed with testing for ALK-positive * have started first-line lorlatinib treatment during the patient selection period In this study, the main objectives are to learn the patient characteristics and the real-world treatment pattern of first-line treatment of lorlatinib in China at a real-world setting.
Interventions
