Trial 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.

About this study

Official title: The Safety and Efficacy of Minocycline as an Anti-Proteinuric in Diabetic Nephropathy

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.

This study was funded by the American Diabetes Association and is not supported by any pharmaceutical company.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in 24 hour urine protein/creatinine ratio (average of 2 values) baseline compared to 6-months in placebo vs minocycline

    Measured: 6 months

Secondary outcomes (3)
  1. Change in average MACR in 24 hour urine, daytime and overnight collections (baseline vs 6 mos)

    Measured: 6 months

  2. Change in average 24 hour urine protein/creatinine in daytime vs overnight collections, baseline vs 6 mos

    Measured: 6 mos

  3. Change in urine and blood biomarkers in minocycline vs placebo treated patients at baseline vs 6 mos

    Measured: 6 mos

Questions about this trial

What is this clinical trial studying?

A study testing Minocycline 100 mg po bid for 6 months in people with Diabetic Nephropathy, run by Lundquist Institute for Biomedical Innovation at Harbor-UCLA Medical Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 24 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 21 May 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in 24 hour urine protein/creatinine ratio (average of 2 values) baseline compared to 6-months in placebo vs minocycline (time frame: 6 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01779089, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 May 2015.
