Management Strategy of 1L Lorlatinib With Hyperlipidemia in Stage IIIB-IV ALK Positive NSCLC

For Patients and Families Brief Title: Management of 1L Lorlatinib with Hyperlipidemia in ALK+ Advanced NSCLC What is this study about? This study is for people with ALK-positive non-small cell lung cancer (NSCLC) who are taking lorlatinib (Lorbrena®) as their first treatment and have developed high cholesterol (hyperlipidemia) as a side effect. Why is this study needed? Lorlatinib is a highly effective targeted therapy, but it frequently causes elevated cholesterol and triglycerides. There is currently no standard guideline on how to best manage this side effect. This study aims to find the best approach to control lipid levels while on lorlatinib treatment. What will happen in this study? The study has two parts: * Part A (Observational) : About 100 participants. Doctors manage hyperlipidemia according to routine clinical practice. Researchers simply observe and record which lipid-lowering treatments are used and how well they work. * Part B (Randomized Controlled Trial) : 60 participants with high-risk factors are randomly assigned to either: * Intensive treatment: rosuvastatin + ezetimibe + evolocumab * Standard treatment: rosuvastatin + ezetimibe What tests are involved? * Blood tests for lipid levels at baseline, Weeks 4, 8, 20, and 24 * Routine CT or MRI scans for tumor assessment * Some participants in Part B may have a non-invasive vascular ultrasound (FMD) test * Total participation per patient: up to 7 months Is this study safe? * ✅ Approved by the Ethics Committee of Sun Yat-sen University Cancer Center * ✅ All drugs used (lorlatinib, statins, ezetimibe, evolocumab) are already approved and widely used * ✅ An independent Data Monitoring Committee (DMC) monitors safety throughout the study * ✅ Participants may withdraw at any time without affecting their regular care For Healthcare Providers Study Title: Management strategy of 1L Lorlatinib with Hyperlipidemia in Stage IIIB-IV ALK positive NSCLC: A multi-center prospective study in China Sp
