INNOVATION Study - Telmisartan (Micardis) in Incipient Diabetic Nephropathy

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
ClinicalTrials.gov Identifier: NCT00153088

Brief Summary:
The aim of this study is to compare the preventive effect of Telmisartan(Micardis) versus placebo control on the transition to overt nephropathy in patients with diabetic nephropathy manifesting microalbuminuria associated with type II diabetes, and to evaluate the efficacy and safety of Telmisart (Micardis, Gliosartan, Kinzal, Kinzalmono, Predxal, Pritor, Samertan, Telmisartan) for diabetic nephropathy patients.

Condition or disease Intervention/treatment Phase
Diabetic Nephropathies Drug: Telmisartan capsule 40 mg Drug: Placebo Drug: Telmisartan capsule 80 mg Phase 4

Detailed Description:

A prospective, randomised, double-blind, multicentric and comparative study to investigate, on a long-term basis, the preventive effect on the transition to overt nephropathy and the safety of Telmisartan (Micardis) against placebo in patients with diabetic nephropathy, manifesting microalbuminuria associated with type II diabetes.

Study Hypothesis:

The hypothesis is that Telmisartan (Micardis) at 40 mg or 80 mg versus placebo control in patients with concurrent type II diabetic mellitus or diabetic nephropathy demonstrating microalbuminuria, has the preventive effect on transition from incipient to overt nephropathy.


The primary endpoint is defined as the transition from incipient to overt nephropathy, and the non-transition curve will be demonstrated based on the Kaplan-Meier method. The evaluation criteria for the point to transition to overt nephropathy is defined as urinary albumin to creatinine ratios at consecutive 2 measuring points increasing over 300 mg/g-Creatinine and excess 30% increase comparing with the baseline value. The curve of non-transition will be compared with Logrank test. Those in BIBR277 groups are sequentially compared with that in the placebo group by the closed testing procedure.
