Summary

Diabetic kidney disease increases the risk of illness and death from heart disease in patients with Type 2 diabetes. Some blood pressure medications called ACE inhibitors and ARBs slow progression of kidney disease, but the dose that can be used is often limited by side effects that are experienced by patients. The most limiting side effects of the current treatments are lowering of the kidney function or blood pressure, and a rise in blood potassium levels. A safe and inexpensive medication that doesn't lower kidney function or blood pressure or raise serum potassium would be useful.

Minocycline is a tetracycline antibiotic with recently appreciated protective properties. In a published journal article by Dr. Isermann, minocycline prevented the death of specialized kidney cells in mice. The kidneys of these mice did not develop diabetic kidney disease when seen under the microscope and the mice experienced only a little bit of protein loss in the urine. In a different published paper, the authors showed that minocycline also decreased kidney injury in a model of non-diabetic kidney disease. A related tetracycline antibiotic was shown to lower urine protein in diabetic patients. These data support a rationale for testing to see if minocycline is safe and helpful in patients with diabetic kidney disease. In this study, all patients will stay on their usual medications for the treatment of diabetic kidney disease. Patients will be given either minocycline (100 mg by mouth twice a day for 24 weeks) or placebo (an inactive capsule taken twice a day for 24 weeks). Minocycline or placebo will be assigned by a process called "randomization", which is like a coin toss. Neither the patient nor the study team will know if the patient is taking placebo or minocycline until the end of the study. The study will assess minocycline safety and test to see if minocycline is helpful or not helpful for the treatment of diabetic kidney disease.
