NCT01412229
This is a non-randomized, open-label phase II trial of 40 patients with poor prognosis head and neck cancer, defined as surgically unresectable and/or ≥N2b disease and judged appropriate for non-surgical definitive therapy.
NCT02106910
Subjects presenting to University of North Carolina at Chapel Hill (UNC) Hospitals for routine endoscopic surveillance examinations for current Barrett's Esophagus (BE) or after successful radiofrequency ablation (RFA) of dysplastic Barrett's Esophagus (BE) will be offered enrollment in the study. After informed consent, and the same day as the endoscopic procedure, the subject will undergo administration of the Cytosponge assay. The patient will then undergo routine endoscopic surveillance, using a standard Seattle biopsy surveillance protocol. The Cytosponge will be placed in fixative and shipped to the Fitzgerald laboratory at the University of Cambridge for processing according to their established protocols. Tissue biopsies will undergo standard processing and Hematoxylin and Eosin (H\&E) staining, with assessment by expert gastrointestinal pathologists at UNC. The primary outcome variables will be sensitivity and specificity of the novel assay, compared against the gold standard of the presence of recurrent BE as detected by upper endoscopy with biopsies. Secondary outcomes include acceptability of the nonendoscopic assay to the patient (assessed by a standardized tool, the Impact of Events Scale, as well as a visual analogue scale), and likelihood of assay positivity as a function of amount of residual disease (as measured by Prague criteria).
