Safety and Efficacy of Different Oral Doses of BAY94-8862 in Japanese Subjects With Type 2 Diabetes Mellitus and the Clinical Diagnosis of Diabetic Nephropathy (ARTS-DN Japan)

Phase 2

Completed

• Conditions: Diabetic Nephropathies
• Interventions: Drug: BAY94-8862; Drug: Placebo; Drug: BAY 94-8862

• Registration Number: NCT01968668
• Lead Sponsor: Bayer

Brief Summary

This study will be conducted in Japanese subjects with type 2 diabetes mellitus and the clinical diagnosis of Diabetic Nephropathy( DN) using a multi-center, randomized, adaptive, double-blind, placebo-controlled, parallel-group design.

Primary objective of the study is investigate the change of Urinary Albumin to Creatine Ratio (UACR) after treatment with different oral doses of BAY94-8862 given once daily from baseline to Visit 8 (Day 90)

Inclusion Criteria

• Japanese subjects with type 2 diabetes mellitus and a clinical diagnosis of DN (Diabetic Nephropathy) treated with at least the minimal recommended dose of an Angiotensin Converting Enzyme Inhibitor (ACEI) and/or Angiotensin Receptor Blocker (ARB)

• Subjects with a clinical diagnosis of Diabetic Nephropathy (DN) based on at least 1 of the following criteria:

  • Persistent very high albuminuria defined as Urinary Albumin to Creatine Ratio (UACR) of >/=300 mg/g (>/=34 mg/mmol) in 2 out of 3 first morning void samples and estimated glomerular filtration rate (eGFR) >/=30 mL/min/1.73 m2 but <90 mL/min/1.73 m2 Chronic Kidney Disease-Epidemiology Collaboration (CKD-EPI) or
  • Persistent high albuminuria defined as UACR of >/=30 mg/g but <300 mg/g (>/=3.4 mg/mmol but <34 mg/mmol) in 2 out of 3 first morning void samples and eGFR>/=30 mL/min/1.73 m2 but <90 mL/min/1.73 m2 (CKD-EPI)

• Serum potassium </=4.8 mmol/L at both the run-in visit and the screening visit
