The project aims to find mechanisms for the abnormal retinal blood flow that in diabetic patients often precedes any evidence of clinical retinopathy and may contribute to the development of retinopathy. Specifically, the projects tests the hypothesis that reduced retinal blood flow found in young patients with type 1 diabetes reflects increased resistance in the small vessels of the retina caused by the formation of small blood clots, called microthrombi; and that antiplatelet agents normalize the reduced retinal blood flow.
NCT00738881
This randomized phase III trial studies pemetrexed disodium to see how well it works compared with erlotinib hydrochloride as second-line therapy in treating patients with non-small cell lung cancer that has spread to other places in the body. Pemetrexed disodium and erlotinib hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether pemetrexed disodium is more effective than erlotinib hydrochloride in treating advanced non-small cell lung cancer.
