The purpose of this study is to determine the maximum tolerated dose of the combination of vorinostat, cisplatin, pemetrexed, and radiation therapy in patients with unresectable stage IIIA/IIIB non-small cell lung cancer.
This phase I trial will escalate doses of the histone deacetylase inhibitor (HDAC) vorinostat to a chemoradiation platform for cisplatin, pemetrexed and radiation to a dose of 70Gy in NSCLC patients with unresectable IIIA and dry IIIB disease. The endpoint will be to determine MTD of the combination.
