Primary outcome [1] 0 0
Number of Subjects With Conversion From Microalbuminuria to Normoalbuminuria - The primary efficacy variable was the fraction of those patients in the ITT population with valid baseline and Week 26 ACRs in whom "therapeutic success" was achieved at Week 26 measured as a conversion of microalbuminuria to normoalbuminuria and at least a 25% reduction in ACR relative to baseline

26 Weeks
Primary outcome [2] 0 0
Number of Subjects With Greater Than 50% Reduction in Microalbuminuria - During the treatment period, KRX-101 is being compared to placebo to assess whether a 50% reduction in microalbuminuria has been achieved.
