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.
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.
