Diagnostic Utility of SGLT1/2 Inhibition to Facilitate Myocardial Glucose Suppression During Evaluation of Cardiac Inflammation on FDG-PET
University of Pennsylvania
Summary
This is a pilot mechanistic study of the diagnostic utility of sodium-glucose cotransporter-1/2 inhibition (SGLT1/2) on myocardial glucose suppression on FDG PET/CT. The investigators will test whether the addition of a SGLT1/2 inhibitor (SGLT1/2i) plus the standard dietary modification (ketogenic diet) will provide enhanced myocardial glucose suppression. The primary objective is to assess rates of complete myocardial glucose suppression (MGS) with 7 days of sotagliflozin 400 mg QD among healthy volunteers on a background of 1 day (N=20) or 3 days (N=20) of the KD. The secondary goal is to investigate the relationship between sotagliflozin, targeted metabolite levels, and myocardial glucose utilization on FDG-PET. Participants will be asked to: * undergo a screening visit that includes blood tests, vitals, and questions regarding health history/medications * take the provided sotagliflozin as instructed for 7 days leading up to the scan * follow a ketogenic diet as instructed for 1 or 3 days leading up to the scan * undergo an FDG PET/CT scan, which includes vitals and blood draws
Description
The purpose of this mechanistic pilot study is to evaluate the effect on myocardial glucose suppression, and therefore on image quality, with the addition of a brief course of an FDA approved SGLT1/2 inhibitor prior to FDG PET/CT scan. FDG PET/CT is a clinically utilized scan for diagnosis of cardiac sarcoidosis following the standard diet and fasting requirements, this study will test the addition of the 7 days of sotagliflozin prior to the scan. Sotagliflozin (INPEFA™) is a sodium-glucose cotransporter-2 inhibitor (SGLT1/2i) Sodium-glucose cotransporter-2 inhibitor that has been studied in…
