To Determine the Effects of Avosentan on Doubling of Serum Creatinine, End Stage Renal Disease and Death in Diabetic Nephropathy

Diabetic Nephropathy Clinical Trial

Official title: ASCEND - A Randomised, Double Blind, Placebo Controlled, Parallel Group Study to Assess the Effect of the Endothelin Receptor Antagonist Avosentan on Time to Doubling of Serum Creatinine, End Stage Renal Disease or Death in Patients With Type 2 Diabetes Mellitus and Diabetic Nephropathy

Status Terminated

Clinical Trial Summary

The purpose of this study is to determine whether avosentan (SPP301) is effective in decreasing morbidity and mortality in patients with diabetic nephropathy.

Clinical Trial Description

Diabetic nephropathy has become the leading cause of end stage renal disease (ESRD) in the western world, accounting for approximately 40% of new cases in the US, and up to 20 to 30% in Europe.

Current treatments for diabetic nephropathy usually try to deal with the underlying diabetes or they aim to reduce cardiovascular risk factors such as hypertension, hyperglycemia, smoking and dyslipidemia. A few recently approved drugs such as irbesartan and losartan (for type 2 diabetic nephropathy) have a renoprotective activity beyond their antihypertensive effect. However, morbidity and mortality rates remain high.

Avosentan may have a positive effect on reducing the amount of protein lost in the urine and if this is the case it will help treat patients with diabetic nephropathy. ;
