Diabetic Nephropathies
Conditions
Brief summary
adding roflumilast to the standard therapy for diabetic nephropathy and studying the progression of many outcomes including urinary albumin to creatinine ratio, estimated GFR, biomarkers of diabetic nephropathy
Interventions
adding one tablet of roflumilast 500 mcg to the standard ACEI (captopril) for diabetic nephropathy management
Placebo

Eligibility
Inclusion criteria
