Devjit Tripathy, M.D.
Professor of Medicine
I have been involved in multiple clinical research studies in the pathophysiology of type 2 diabetes. My main focus has been dissecting the underlying mechanisms of insulin resistance and beta cell dysfunction, particularly how elevated free fatty acids induce insulin resistance and the natural history of development of type 2 diabetes as well as pharmacological interventions to prevent type 2 diabetes. I am currently involved in the validation and mechanism of action of many of the more recent medications used to treat and prevent Type 2 diabetes. My other field of interest is metabolic effects of sex hormones, particularly long-term effects of testosterone and estrogen.

Research & Grants
Since my initial training days in Endocrinology in India in 1994, I have been pursuing a career in academic medicine. My experience as an endocrinologist for the last 20 years has given me a unique perspective when it comes to recognizing the need for better methods of diagnosis, prevention, and management of Type 2 diabetes. My expertise in the field lies in pathophysiology of T2DM and mechanism of action of newer anti-diabetic medications.
Funding Agency NIH Title Regulation of Hepatic and Peripheral Glucose Metabolism Status Active Period 7/2012 - 6/2017 Role Co-Investigator Grant Detail Dr. Ralph DeFronzo is the PI for this study. This study will examine the effect of chronic glucose infusion on insulin signaling in healthy individuals. I am in charge of all the clinical procedures at the BRU, and also the data analysis and eventually will contribute to the publication of the manuscript. The study is currently on going and we expect to complete it by 2016. Funding Agency NIH Title Diabetes effects of long-term implant survival and success. Status Active Period 7/2013 - 5/2017 Role Co-Investigator Grant Detail Dr. Tom Oates is the PI for this project. This project will examine the effect of glycemic control on long-term success of dental implants. I am the endocrinology consultant for this study.

A multicenter study examining the effect of long-acting Insulin- Insulin Degludec on cardiovascula Status Active Period 6/2014 - 6/2019 Role Co-Investigator Grant Detail A trial comparing cardiovascular safety of insulin degludec versus insulin glargine in subjects with type 2 diabetes at high risk of cardiovascular events. A multicenter study examining the effect of long-acting Insulin- Insulin Degludec on cardiovascular end points in T2DM. Sponsor- Novo- Nordisk. Funding Agency Astra Zeneca Title Exenatide for Cardiovascular Event Trial Status Active Period 3/2012 - 12/2017 Role Principal Investigator Grant Detail A randomized placebo controlled clinical trial to evaluate cardiovascular outcomes after treatment with Exenatide once weekly in patients with type 2 Diabetes mellitus. A multicenter study examining the effect of long-acting Exenatide on cardiovascular end points in T2DM.
Enrollment for this study has been completed and currently 100 patients with T2DM are being followed.
