Pembrolizumab, Paclitaxel, Carboplatin, and Radiation Therapy in Treating Patients With Stage II-IIIB Non-Small Cell Lung Cancer

This phase I trial studies the side effects, best dose, and best way to give pembrolizumab when given together with paclitaxel, carboplatin, and radiation therapy in treating patients with stage II-IIIB non-small cell lung cancer. Monoclonal antibodies, such as pembrolizumab, may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as paclitaxel and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Radiation therapy uses high energy x-rays to kill tumor cells and shrink tumors. Giving pembrolizumab together with paclitaxel, carboplatin, and radiation therapy may kill more tumor cells.
