Study summary

Prospective, randomized, double-blind, placebo controlled, 12-week, multicenter study. The objective of the study is to evaluate the efficacy and safety of once daily administration of atrasentan tablets compared to placebo in reducing residual albuminuria in Japanese Type 2 diabetic patients with nephropathy who are treated with the maximum tolerated labeled dose for hypertension of a RAS (renin angiotensin system) inhibitor.

What researchers measure

Primary outcomes

  1. The change from baseline to each post-baseline visit in log-transformed UACR (urinary albumin to creatinine ratio)

    Time frame: Up to Week 12

Secondary outcomes

  1. The proportion of subjects who have achieved at least 30% reduction on UACR (Urinary Albumin to Creatinine Ratio) who have not had any form of treatment-emergent edema with moderate or severe severity.

    Time frame: Up to Week 12

  2. The change from baseline to each post-baseline visit on log-transformed UACR (Urinary Albumin to Creatinine Ratio) and estimated GFR (Glomerular Filtration Rate)

    Time frame: Up to Week 12

  3. The proportion of subjects who achieve various percent of reduction in UACR (Urinary Albumin to Creatinine Ratio) from baseline to final

    Time frame: Up to Week 12
