Study Details

Study Description

Brief 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.

Condition or Disease Intervention/Treatment Phase
  • Drug: Atrasentan low dose group
  • Drug: Atrasentan high dose group
  • Drug: Atrasentan placebo group

Arms and Interventions

Arm Intervention/Treatment
Experimental: ABT-627, Low dose

Drug: Atrasentan low dose group
Subjects will take two tablets daily of one of those which are atrasentan low dose, atrasentan high dose or atrasentan placebo for 12 weeks during the treatment period.

Experimental: ABT-627, High dose

Drug: Atrasentan high dose group
Subjects will take two tablets daily of one of those which are atrasentan low dose, atrasentan high dose or atrasentan placebo for 12 weeks during the treatment period.

Placebo Comparator: ABT-627, Placebo

Drug: Atrasentan placebo group
Subjects will take two tablets daily of one of those which are atrasentan low dose, atrasentan high dose or atrasentan placebo for 12 weeks during the treatment period.

Outcome Measures

Primary Outcome Measures

  1. The change from baseline to each post-baseline visit in log-transformed UACR (urinary albumin to creatinine ratio) [Up to Week 12]

Secondary Outcome Measures

  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. [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) [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 [Up to Week 12]
