Reducing Residual Albuminuria in Subjects With Diabetes and Nephropathy With Atrasentan
August 25, 2017 updated by: AbbVie (prior sponsor, Abbott)
Reducing Residual Albuminuria in Subjects With Diabetes & Nephropathy With Atrasentan - A Phase 2b, Prospective, Randomized, Double-Blind, Placebo-Controlled Trial to Evaluate Safety & Efficacy in Japanese Subjects
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.

Description
Inclusion Criteria:

Estimated GFR (Glomerular Filtration Rate) is greater than or equal to 30 and less than or equal to 75 mL/min/1.73m2 by the CKD (chronic kidney disease)
- Epidemiology Collaboration (EPI) formula.
- UACR (Urinary Albumin to Creatinine Ratio) is greater than or equal to 200 mg/g as determined by the geometric mean of the three morning void urine specimens obtained at Run-in period.
- Serum albumin is greater than or equal to 3.0 g/dL. BNP (B-type Natriuretic Peptide) is less than or equal to 200 pg/mL.
- SBP (Systolic Blood Pressure) is greater than or equal to 110 mmHg and less than or equal to 160 mmHg. HbA1c (Glucosylated Hemoglobin A1c) is less than or equal to 12% and serum potassium is less than or equal to 5.5 mEq/L.
Exclusion Criteria:
