The study closed per PI decision due to completion of the biopsy substudy and slow accrual

CREST-KT is a single-center, double-blinded, randomized trial of empagliflozin therapy in 72 kidney transplant recipients with (n=36) and without type 2 diabetes (n=36). After evenly dividing patients by type 2 diabetes diagnosis, patients will be randomized 2:1 to empagliflozin 10mg versus placebo.

A screening visit will occur at which time an informed consent will be obtained, and eligibility determined. Women of childbearing potential will have a serum pregnancy test performed. This will be followed by a baseline visit. A renal biopsy and a 3D echocardiogram will be performed. At the next visit randomization will be performed and the subjects will receive their study medication, either empagliflozin or a placebo. Following the randomization visit the subject will return every 3 months (visits 2-7) for a total of 6 visits spanning 18 months. At each visit vital signs and weight will be taken. Other procedures include labs drawn for hematology, basic chemistry, coagulation, Glycated hemoglobin and serum insulin. A 3 D echocardiogram is repeated on Visits 4 and 6. A renal biopsy is repeated on Visit 3.
