This clinical trial is focused on studying treatments for metastatic non-squamous non-small-cell lung cancer (NSCLC), which is a type of advanced lung cancer. The study involves several medications, including Pembrolizumab, Pemetrexed, Carboplatin, Cisplatin, and Olaparib. Pembrolizumab, also known by its code name MK-3475, is a medication that helps the immune system fight cancer. Olaparib, with the code name MK-7339, is a medication that targets cancer cells directly. Pemetrexed, Carboplatin, and Cisplatin are chemotherapy drugs that help stop the growth of cancer cells.
The purpose of this study is to compare the effectiveness of different treatment combinations in improving the survival of patients with this type of lung cancer. Participants will receive a combination of Pembrolizumab with either Pemetrexed and a platinum-based drug (Carboplatin or Cisplatin) or Olaparib. After the initial treatment phase, participants will continue with either Olaparib or Pemetrexed as maintenance therapy. Some participants may receive a placebo during the maintenance phase to help researchers understand the effects of the medications better.
The study will take place over several months, with regular check-ups and assessments to monitor the participants’ health and the cancer’s response to the treatment. The goal is to determine which combination of treatments offers the best outcomes in terms of slowing down the progression of the cancer and improving overall survival. Participants will be closely monitored for any side effects or changes in their condition throughout the study.
