This clinical trial is focused on studying a type of lung cancer known as Non-Small Cell Lung Cancer (NSCLC), specifically in patients whose cancer is locally advanced and cannot be removed by surgery. The study is looking at patients with a specific genetic change in their cancer called an EGFR mutation. The treatment being tested is a medication called Osimertinib, which is also known by its code name AZD9291. This medication is being compared to a placebo to see if it can help prevent the cancer from getting worse after patients have already received a combination of chemotherapy and radiation therapy.
The purpose of the study is to see how effective Osimertinib is in keeping the cancer from progressing. Participants in the study will be randomly assigned to receive either Osimertinib or a placebo. The study is designed to be “double-blind,” which means neither the participants nor the researchers will know who is receiving the actual medication and who is receiving the placebo. This helps ensure that the results are not biased. The medication is taken orally in the form of film-coated tablets.
Throughout the study, participants will be monitored regularly to check on their health and to see how the cancer is responding to the treatment. This will involve various assessments, including physical exams and possibly imaging tests. The study aims to provide valuable information on whether Osimertinib can be an effective maintenance therapy for patients with this type of lung cancer, potentially improving their quality of life and extending the time before the cancer progresses.
