NCT01462383
Primary Objective: -Evaluate incidence of cardiac complications in Phase I patients. Secondary Objective: -To identify variables (i.e. number of electrocardiograms (EKG) performed) that lead to the detection of cardiac events.
NCT00790452
Primary objective: To determine whether aspirin (ASA) can lower the incidence of Venous Thromboembolism(VTE) in patients with Glioblastoma (GBM). Secondary objectives: To determine clinical and laboratory factors which are associated with increased risk of VTE If it is determined that ASA reduces the incidence of VTE in patients with GBM, then to determine the clinical and laboratory factors which are associated with an increased benefit from the drug.
NCT00844077
Barrett's esophagus can progress to esophageal cancer, but it doesn't always. Current treatment is frequent surveillance via upper endoscopy with multiple biopsies to look for changes (dysplasia). Pathologists vary dramatically in their interpretation of Barrett's Metaplasia versus dysplasia and consensus is very difficult to achieve. The investigators propose a longitudinal study of subjects with confirmed Barrett's intestinal metaplasia without dysplasia to look for predictive factors for transformation to dysplasia or cancer. Potential biomarkers can be found in serum, plasma, urine, frozen or fixed Barrett's and Normal esophageal mucosa. In addition, the investigators are testing a brushing technique from CDx, Inc. for predictive factors. Subjects must have pathologically confirmed Barrett's intestinal metaplasia without history of dysplasia to be on this longitudinal study.
