Brief Summary
NADPH oxidase enzymes (NOX) have been implicated in the development of several diabetic complications including diabetic nephropathy. GKT137831 is the first in class NOX1/4 inhibitor. The primary objective of this study is to evaluate the efficacy of oral GKT137831 in patients with residual albuminuria despite maximal inhibition of the renin angiotensin aldosterone system.

Outcome Measures
Primary Outcomes (1)
Albuminuria Absolute Value and Ratio to Baseline by Study Visit and Treatment Group
UACR from baseline to Visits 9, 10, and 11 (i.e. weeks 8, 10 and 12 of the treatment period, respectively). Baseline for UACR is defined as the geometric mean of the geometric means of the UACR values measured on Day-14 (visit 4) and Day 1 (visit 5). End of treatment is defined as the geometric mean of the geometric means of the UACR values measured at week 8 (visit 9), week 10 (visit 10) and week 12 (visit 11).
Visit 4 (week -2) to visit 11 (week 12)
Secondary Outcomes (5)
Glucose Metabolism by Homeostatic Model Assessment (HOMA)
Visits 5 (week 0), 8 (week 6), and 11 (week 12)
Glucose Metabolism HbA1c
Visit 5 (week 0), 8 (week 6) and 11 (week 12)
24 Hours Albumin Excretion
Visits 5 (week 0) and 11 (week 12)
24 Hours Urine UACR
Visits 5 (week 0) and 11 (week 12)

Eligibility Criteria
You may qualify if:
- Male or female aged 18 to 80 years
- History of type 2 diabetes, defined as fasting plasma glucose ≥7.0 mmol/L (126 mg/dL) or a glycated hemoglobin (HbA1c) \>6.5% (48 mmol/mol) on at least 2 occasions prior to screening.
- Albuminuria defined as a UACR of 300 to 3500 mg/g.
- An eGFR ≥30 mL/min/1.73 m2, as calculated by the CKD-EPI formula.
- Must be taking an ACEI or an ARB for at least 6 weeks prior to the first screening visit (Visit 1) and during the screening period. The dose must have been stable for at least 4 weeks prior to the first screening visit (Visit 1). Combination therapy associating an ACEI and an ARB is not permitted.
You may not qualify if:
- History of type 1 diabetes
- Any other non-diabetic kidney disease(s) except for hypertensive nephropathy which is acceptable.
- Diagnostic or interventional procedure requiring a contrast agent within 4 weeks of the first screening visit (Visit 1) or planned during the study.
- History of renal transplant or planned renal transplant during the study.
- A history of acute renal dialysis or acute kidney injury (defined according to the Kidney Disease: Improving Global Outcomes \[KDIGO\] definition) within 12 weeks of the first screening visit (Visit 1)
- HbA1c level \>11% (97 mmol/mol).
- History of hypothyroidism requiring hormone replacement therapy.
- History of active cardiovascular disease
- A personal or family history of long QT syndrome.
- Administration of any investigational product within 30 days or within 5 half-lives of the investigational agent
