SPP100 (Tekturna/Rasilez) demonstrates potential to protect kidneys from damage
Potential kidney-protective benefits of SPP100 independent of proven blood pressure reduction
In the AVOID study, Rasilez/Tekturna1 reduced albuminuria, a key indicator of kidney disease, 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 disease,.
In patients with diabetes, the first sign of kidney disease is the presence of albumin in the urine, a condition called albuminuria. Albuminuria is a key indicator of kidney disease and cardiovascular disease. Reducing albuminuria is associated with a reduction of cardiovascular events 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 pressure,.
Dr. Thomas Littke, Head of Clinical Research & Development commented: "Type 2 diabetic patients with high blood pressure are very fragile patients. Importantly, SPP100 further lowered albuminuria by 20% in these patients, independent of blood pressure, when administered on top of losartan (ARB), a standard therapy used to treat diabetic kidney disease. Albuminuria is an important indicator of kidney disease and the level of albuminuria predicts cardiovascular mortality in patients with diabetes".
Dr. Alice Huxley, CEO stated: "We are delighted that the published data in the prestigious New England Journal of Medicine show the potential of SPP100 (Rasilez/Tekturna) in kidney protection. This is very important for the future positioning of renin inhibition in medical practice. Speedel's next generation renin inhibitors are specifically designed to enhance the effects of lowering of albuminuria to aid in kidney protection."
AVOID study results
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/g. 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). Furthermore, a quarter of patients taking Rasilez/Tekturna added to losartan experienced albuminuria reductions greater than 50% compared to those patients taking losartan alone.
Data from AVOID further showed that Rasilez/Tekturna added to the maximum dose of losartan had similar rates of adverse events as the placebo plus losartan group. Hyperkalemia (elevated potassium levels) was reported as an adverse event in 5.0% of patients taking Rasilez/Tekturna1 in addition to losartan, compared to 5.7% of those taking placebo plus losartan. 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 losartan.
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 failure,.
About SPP100 (aliskiren, Tekturna/Rasilez)
SPP100 (aliskiren, Tekturna/Rasilez1) is the first-in-class oral direct renin inhibitor. The development of SPP100 is the result of over 20 years of research on renin. Renin is the rate-limiting enzyme at the top of the Renin Angiotensin System (RAS), a process leading to high blood pressure and organ damage. The RAS is a cascade, starting with renin, leading to angiotensin I and finally to angiotensin II. Angiotensin-converting enzyme inhibitors (ACE-Is) and angiotensin II receptor antagonists (ARBs) have been developed to block this system "down stream" and have shown clinical efficacy in patients with hypertension and other cardiovascular diseases.
By inhibiting renin at the top of the RAS, SPP100 decreases the system's activity, as measured by plasma renin activity (PRA). Lowering PRA is believed to be very important in end-organ protection (e.g. heart and kidney). PRA is an independent risk factor and direct surrogate marker for several cardio-renal diseases, such as myocardial infarction and chronic renal disease. Direct renin inhibitors lower PRA whereas most current leading anti-hypertensive drug classes such as ACE-Is and ARBs increase PRA levels.
Speedel in-licensed SPP100 from Novartis in 1999 and successfully completed 18 clinical trials, through Phase I and II in about 500 patients and healthy volunteers. Based on the results generated during this programme, Novartis exercised a license-back option in 2002, and subsequently Novartis started trials with SPP100 in Phase III as monotherapy for hypertension and in Phase IIb as combination therapy. Regulatory approval was given by the US FDA in March 2007 and by the EU in August 2007. A first fixed-dose combination of SPP100 and the diuretic HCT was approved in the US in January 2008.
Speedel believes that it is the first company to establish successfully a clinical proof of concept in Phase II and to have developed and filed for patent protection a commercially viable manufacturing process for a renin inhibitor, an area of industry research for over 20 years. In a Phase II study of 200 patients conducted by Speedel, it was demonstrated that SPP100 achieves dose-dependent blood pressure reduction. The study also showed that 150mg and 300mg SPP100 once daily were comparable to Losartan 100mg, which is double the usual starting dose of this ARB.
