New Data Show Potential of Rasilez to Protect Kidneys from Damage Independent of Its Proven Ability to Lower Blood Pressure
• AVOID study shows potential kidney protection benefits of Rasilez in type 2 diabetic patients with kidney disease and high blood pressure1
• Rasilez reduced albuminuria, a key indicator of kidney disease, by an additional 20% when added to maximum dose of angiotensin-receptor blocker losartan1,2
• First clinical trial to present data on potential kidney-protective benefits of Rasilez, independent of its proven blood pressure reductions3
• Damage to kidneys caused by diabetes is leading cause of end-stage renal disease in developed countries1
BASEL, Swizterland, June 4, 2008 — Data published in this week’s New England Journal of Medicine demonstrate that the first-in-class direct renin inhibitor Rasilez® (aliskiren), known as Tekturna® in the US, may have potential kidney-protective benefits that are independent of its already proven ability to provide powerful blood pressure reductions1,3. Damage to the kidneys caused by diabetes is the leading cause of end-stage renal disease in developed countries, affecting more than 1.5 million people worldwide1,4.
In the AVOID study, Rasilez/Tekturna reduced albuminuria by an additional 20% in type 2 diabetic patients with kidney disease who also had a diagnosis of high blood pressure. These patients were already taking the maximum dose of the angiotensin-receptor blocker (ARB) losartan, which has been shown to slow the progression of diabetic kidney disease1,5.
In patients with diabetes, the first sign of kidney disease is the presence of albumin in the urine, a condition called albuminuria2. Albuminuria is a key indicator of kidney disease and cardiovascular disease2. Reducing albuminuria is associated with a reduction of cardiovascular events6 and slows the progression of kidney disease, which can reduce the risk of chronic kidney failure in type 2 diabetic patients with kidney disease and high blood pressure7,8.
“These results show the potential of Rasilez to treat type 2 diabetic patients with kidney disease who are at risk of kidney failure and cardiovascular diseases,” said Professor Hans-Henrik Parving, MD, of the University Hospital in Copenhagen, Denmark, the AVOID study lead investigator. “The addition of Rasilez to the maximum recommended dose of losartan in patients with type 2 diabetes, kidney disease and high blood pressure resulted in albuminuria reductions independent of the blood pressure lowering effects of Rasilez.”
* Rasilez® is the trade name for aliskiren throughout the world, except in the US where it is known as Tekturna®.
In the 24-week AVOID study involving nearly 600 patients, Rasilez/Tekturna was added to the treatment regimen of type 2 diabetic patients diagnosed with high blood pressure who were already receiving losartan and had albuminuria levels greater than 200 mg/g1. The study showed that overall Rasilez/Tekturna (150 mg increasing to 300 mg daily) reduced albuminuria by an additional 20% when added to the maximum dose of losartan (100 mg)1. Furthermore, a quarter of patients taking Rasilez/Tekturna added to losartan experienced albuminuria reductions greater than 50% compared to those patients taking losartan alone1.
“In addition to providing powerful blood pressure reductions that last beyond 24 hours both as monotherapy and in combination, Rasilez has now shown the potential to protect against kidney damage in type 2 diabetic patients diagnosed with high blood pressure who are extremely vulnerable to chronic kidney disease,” said Trevor Mundel, MD, Head of Global Development Functions at Novartis Pharma AG.
Data from AVOID further showed that Rasilez/Tekturna added to the maximum dose of losartan had similar rates of adverse events to the placebo plus losartan group1. Hyperkalemia (elevated potassium levels) was reported as an adverse event in 5.0% of patients taking Rasilez/Tekturna in addition to losartan, compared to 5.7% of those taking placebo plus losartan1. Hyperkalemia as a laboratory abnormality was reported in 13.7% of patients taking Rasilez/Tekturna in addition to losartan, compared to 10.8% of the patients taking placebo plus losartan1.
The AVOID study is one in a series of trials in the landmark ASPIRE HIGHER clinical trial program, the largest ongoing cardio-renal outcomes program, which involves more than 35,000 patients in 14 trials including three new mega-trials. The ASPIRE HIGHER program is studying the effect of direct renin inhibition in a variety of conditions, including diabetic kidney disease and heart failure1,9.
Rasilez/Tekturna acts by directly inhibiting renin3, an enzyme that triggers a process leading to high blood pressure and organ damage. Rasilez/Tekturna is approved in more than 40 countries. Tekturna was approved in the US in March 2007, and in the European Union in August 2007 under the trade name Rasilez. Tekturna HCT®, the first single-dose combination involving Tekturna, was approved in the US in January 2008. Rasilez/Tekturna was discovered by Novartis and developed in collaboration with Speedel.
