Empaglifozin in Early Diabetic Kidney Disease

Withdrawn before enrolling · Phase 3 · Has a placebo group

Conditions studied: Diabetic Kidney Disease, Diabetes Mellitus Type 2

In brief

Background: Diabetes is common among American Indian people and diabetic kidney disease is a common complication. Kidney disease caused by diabetes can lead to the need for kidney replacement, by dialysis or kidney transplant, and is also associated with higher risk of early death. A new diabetes medicine called empagliflozin may slow kidney disease from type 2 diabetes. Researchers want to learn if it protects the kidneys when used in very early stages of diabetic kidney disease. Objectives: To see if empaglifozin delays kidney disease development. Eligibility: Adults 18-64 years old who are at least half American Indian and have had type 2 diabetes at least 5 years Design: Participants will be screened with health questions, blood pressure, and blood and urine tests. Participants will have: * Medical history * Physical exam * Blood, urine, and stool samples taken * Scan of the kidneys and liver. Participants will lie on a table that slides into an MRI machine. They will hold their breath for up to 20 seconds and the MRI machine will take images of their kidneys and liver. They will then repeat this with a small device that vibrates on their side. * Kidney tests. A needle will be placed in a vein in each arm for 4 hours. Blood pressure will be taken. Participants will drink several quarts of water and urinate every 20 minutes. Urine and blood samples will be collected. Two liquids will be injected into their veins to measure kidney function. * Photos of the back of the eyes * Kidney biopsy. Participants will have a scan and get drugs to make them sleepy. Up to four very small pieces of kidney will be removed by needle. After the biopsy participants will be monitored for at least 4 hours. * Nerve tests Participants will take the study drug or placebo pill once a day. Participants will attend for tests every twelve weeks and have more extensive kidney function tests once a year. After 3 years, participants will have another kidney biopsy and then stop taking the study drug. They will have a final kidney function test 2 months later.

Who can join

Age: 18 and older, up to 64. Sex: any. Healthy volunteers: not accepted.

You may not qualify if…

• Volunteers will be excluded prior to enrollment for the following reasons:
• Clinically significant disorders of the liver [cirrhosis, portal hypertension, hepatitis, increased bilirubin (greater than or equal to 1.5 mg/dl), cardiovascular disease (angina pectoris, history of myocardial infarction, heart failure, cerebrovascular disease, peripheral vascular disease, pulmonary diseases (asthma and restrictive or obstructive lung disease requiring therapy), renal-urinary disorders (calculi, urinary tract obstruction, glomerulonephritis, chronic infection), gastrointestinal disorders (nausea, vomiting, diarrhea or anorexia sufficient to cause weight loss or wasting), or hematocrit levels less than or equal to 30 percent or >55 percent in women or greater than or equal to 35 percent or >60 percent in men.
• Prior treatment with SGLT2 inhibitors.
• Renovascular or malignant hypertension; uncontrolled hypertension (systolic blood pressure greater than or equal to 160 or diastolic greater than or equal to 95 mm Hg) despite treatment with three antihypertensive drugs.
• Hematuria of unknown etiology. Prior to entry into the study, any participant with hematuria should be evaluated, the etiology established and documented, and treatment rendered as appropriate.
• Chronic debilitating disorders with or without treatment (e.g., systemic lupus erythematosus (SLE), cancer, amyloidosis, and chronic infection) that would interfere with the assessment of kidney function or that might reduce the chances of survival for a sufficient length of time to evaluate the efficacy of treatment.
• Currently receiving a drug regimen that includes: steroids, immunosuppressants, or investigational new drugs.
• Pregnancy. Boerhinger Ingelheim, the manufacturer of empagliflozin, do not recommend its use during the second or third trimester of pregnancy. Moreover, we do not wish to expose pregnant women to conscious sedation that is used during the kidney biopsies or to the intravenous filtration markers iothalamate and para-aminohippurate needed for the renal clearance studies. Women of childbearing potential must have a negative pregnancy test prior to entry and every 3 months during the study, and agree to using an effective form of contraception throughout the study, such as the oral contraceptive pill or an intrauterine device. Women who are planning a pregnancy in the next three years will be excluded.
• Symptoms of inability to empty the bladder. The urinary clearance method is only accurate if complete bladder emptying is possible.
• Hypersensitivity to empagliflozin or iodine.
• Bleeding disorders or requirements for anticoagulation or platelet inhibitors which cannot be safely interrupted, since kidney biopsies cannot be performed safely in these individuals.
• Massive obesity with body mass index greater than or equal to 45 kg/m(2). Kidney biopsies are more difficult and present greater hazards to people with massive obesity.
• Allergy to iodine-containing contrast material.
• Non-diabetic kidney disease based on clinical history or kidney biopsy examination.
• History of severe recurrent kidney infections.
• History of osteoporotic fracture.
• Conditions likely to interfere with informed consent or compliance with the protocol.
