Effect of a Vitamin D Analogue vs Placebo on p-NT-proBNP in Patients With Type 1 DM and Diabetic Nephropathy

April 12, 2012 updated by: Peter Rossing

The Effect of Paricalcitol Versus Placebo on Plasma N-Terminal-proBNP in Patients With Type 1 Diabetes Mellitus and Diabetic Nephropathy

The primary objective is to assess the impact of three months of treatment with an active vitamin D analogue on a risk marker for excess overall mortality and cardiovascular morbidity/mortality in Type 1 diabetic patients with diabetic kidney disease. The hypothesis is that active vitamin D analogue treatment reduces the risk of cardiovascular morbidity and mortality in patients with type 1 diabetic kidney disease.
