What is the SONAR Study?

The purpose of this study is to evaluate whether or not atrasentan is effective in delaying the worsening of kidney disease by comparing the time to serum creatinine doubling or the onset of end stage renal disease in subjects with type 2 diabetes and kidney disease. Another purpose of this study is to test the safety of atrasentan.

In addition, this study will compare atrasentan with a placebo to see if taking atrasentan is better than taking a placebo. The placebo is a tablet that looks like a drug but has no drug or other active ingredient in it.
