Healthy volunteers: no

Brief summary:
The purpose of this study is to test the efficacy and safety on daily oral doses of TAK-272 5 mg, 20 mg, 40 mg and 80 mg in patients with type 2 diabetes mellitus and microalbuminuria by randomized, double-blind, placebo-controlled, parallel-group comparison in order to determine the clinical dose of TAK-272.

Detailed description:
The drug being tested in this study is called TAK-272. This study evaluated the dose-response relationship of the efficacy and safety of TAK-272 in participants with type 2 diabetes mellitus and microalbuminuria.

The study enrolled 415 patients. Participants were randomly assigned to one of the 6 treatment groups:

* TAK-272 5 mg
* TAK-272 20 mg
* TAK-272 40 mg
* TAK-272 80 mg
* Candesartan cilexetil 8 mg
* Placebo (dummy inactive pill) for TAK-272 or Candesartan cilexetil - this was a tablet that looks like the study drug but had no active ingredient

All participants were administered tablets, orally at the same time each day for 12 weeks in double-blind manner. Participants were administered TAK-272 placebo 4 tablets and Candesartan cilexetil placebo one tablet for 4 weeks (Week -4 to 0) in placebo run-in period and follow-up period (Week 12-14).

This multi-center trial was conducted in Japan. The overall time to participate in this study is 22 weeks including 2 weeks of follow-up assessment period after last dose of study drug. Participants made multiple visits to the clinic during these periods.
