This study aims to understand how well the drug osimertinib, with or without chemotherapy, works for people with a certain kind of lung cancer called EGFR-mutated Non-Small Cell Lung Cancer (NSCLC). The EGFR mutation involves changes in a gene that can make cancer cells grow faster.
Patients will not receive any new or experimental treatment; instead, researchers will observe those already receiving standard care. This means doctors will use routine treatments and note how patients respond. Up to 538 patients will join, and their progress will be tracked.
- The study is observational, meaning no new treatments are given.
- Doctors decide if osimertinib is used alone or with chemotherapy.
- The study involves up to 538 participants, gathering routine data.
To join, patients must be adults with advanced NSCLC and a confirmed EGFR mutation. They should not be in any other cancer treatment trial. The study will help scientists learn more about the safety and effectiveness of these treatments.
