Chemotherapy and Radiation Therapy With or Without Metformin Hydrochloride in Treating Patients With Stage III Non-small Cell Lung Cancer

This randomized phase II trial studies how well chemotherapy and radiation therapy given with or without metformin hydrochloride works in treating patients with stage III non-small cell lung cancer. Drugs used in chemotherapy, such as carboplatin and paclitaxel, 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. Metformin hydrochloride may shrink tumors and keep them from coming back. It is not yet known whether chemotherapy and radiation therapy is more effective when given with or without metformin hydrochloride in treating stage III non-small cell lung cancer.

Cisplatin and Etoposide With or Without Veliparib in Treating Patients With Extensive Stage Small Cell Lung Cancer

This randomized phase I/II trial studies the side effects and best dose of veliparib when given together with or without cisplatin and etoposide and to see how well they work in treating patients with extensive stage small cell lung cancer or large cell neuroendocrine non-small cell lung cancer that has spread to other parts of the body. Drugs used in chemotherapy, such as cisplatin and etoposide, 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. Veliparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving cisplatin and etoposide with or without veliparib may work better in treating patients with extensive stage small cell lung cancer or metastatic large cell neuroendocrine non-small cell lung cancer.
