This clinical trial is focused on studying treatments for a type of lung cancer known as non-squamous non-small cell lung cancer (NSCLC). The study involves several medications, including Tiragolumab, Atezolizumab, Pembrolizumab (also known by its code name MK-3475), and chemotherapy drugs Pemetrexed and Carboplatin/Cisplatin. The purpose of the study is to evaluate the effectiveness of these treatments in patients who have not received prior treatment for their advanced lung cancer.
Participants in the study will be randomly assigned to one of two groups. One group will receive a combination of Tiragolumab and Atezolizumab along with Pemetrexed and Carboplatin/Cisplatin. The other group will receive Pembrolizumab with Pemetrexed and Carboplatin/Cisplatin. Some participants may receive a placebo instead of Tiragolumab. The study will monitor how well the cancer responds to these treatments and how long patients live without the cancer getting worse.
The trial will take place over a period of time, with regular assessments to check the progress of the disease and the overall health of the participants. The study aims to provide valuable information on the best treatment options for patients with this type of lung cancer, focusing on improving survival rates and quality of life. Participants will receive their treatments through an intravenous infusion, which means the medication is given directly into a vein.
