This clinical trial is focused on studying treatments for Non-Small Cell Lung Cancer (NSCLC), which is a type of lung cancer that is common and can be challenging to treat when it reaches an advanced stage. The study will explore the effectiveness and safety of different therapies for patients with locally advanced, unresectable Stage III NSCLC. The treatments being tested include Alecensa (also known by its code name RO5424802), which contains the active substance alectinib, and IMFINZI, which contains the active substance durvalumab. Another treatment option being evaluated is entrectinib, which is a type of medication known as a tyrosine kinase inhibitor.
The purpose of the study is to compare these treatments in patients who have specific biomarkers, which are unique characteristics found in their cancer cells. These patients have already received a combination of chemotherapy and radiation therapy, known as chemoradiotherapy, and have not shown any progression of their disease on imaging tests. The study will assess how well these treatments work in preventing the cancer from getting worse, which is referred to as progression-free survival.
Participants in the study will receive one of the treatments, and some may receive a placebo. The study will monitor the patients over a period of time to observe the effects of the treatments on their cancer and overall health. The trial aims to provide valuable information on the best treatment options for patients with this type of lung cancer, helping to improve future care and outcomes for those affected by NSCLC.
