     Dr. Imperiale is a Professor of Medicine in IU School of Medicine’s Division of Gastroenterology/Hepatology and staff gastroenterologist serving patients in four major Indiana hospitals. He holds research appointments in the IU Center for Health Services and Outcomes Research, the VA Center for Health Information and Communication, and Regenstrief Institute's William M. Tierney Center for Health Services Research.  His interests include tailoring screening for colorectal cancer based on individual patient risk, and using quantitative research methods in studying prevention of cirrhosis complications. Secondary research interests encompass prognosis and management of acute upper gastrointestinal hemorrhage, and assessment of new technologies to the application of digestive diseases.

 

   Recent recognition includes the Indiana University Trustee Teaching Award and Regenstrief Institute’s Outstanding Investigator Award.  Dr. Imperiale has mentored over thirty medical residents, faculty, and fellows. He is a named Fellow in the American Gastroenterological Association, a Member of the Association of American Physicians, and serves on the Editorial Boards of the journals, Annals of Internal Medicine and Evidence-Based Gastroenterology.  Dr. Imperiale’s publications include over 150 peer-reviewed articles.

Active Projects

I. VA Cooperative Studies Program (2010-2015)

"Colonoscopy vs. Fecal Immunochemical Testing in Reducing Mortality from Colorectal Cancer (CONFIRM)" (PI) 

This study is to determine the true comparative effectiveness of colonoscopy relative to other proven non-invasive options.

 

II. Exact Sciences Corporation (2011-2015)

"Multi-Target Colorectal Cancer Screening Test for the Detection of Colorectal Advance Adenomatous Polyps and Cancer: DeeP-C Study." (PI)

Study is to determine the sensitivity and specificity of the Exact Colorectal Cancer (CRC) screening test for colorectal cancer, using colonoscopy as the reference method. The secondary objective is to compare the performance of the Exact CRC screening test to a commercially available FIT assay, both with respect to cancer and advanced adenoma.

 

III. Exact Sciences Corporation (2015-2019)

“”A Longitudinal Study of CologuardTM in an Average Risk Population Assessing a Three Year Test Interval” (PI)

The study objective is to collect longitudinal data on subjects prescribed Cologuard over the course of 3 years, to determine predictive value of the test, and to compare the observed versus expected reduction in colorectal cancer incidence.
