RIDGEFIELD, Conn., June 18, 2007 /PRNewswire/ -- Today, results from AMADEO*, one of a series of studies comparing two angiotensin receptor blockers (ARBs) in hypertensive patients with diabetic nephropathy, were presented at the 17th annual European Meeting on Hypertension in Milan, Italy.
The randomized, double-blind, forced titration, parallel group, multicenter study included 860 hypertensive patients (>130/80mmHg) with type 2 diabetes and overt nephropathy from 124 centers in 10 countries. Patients were randomized to receive treatment with either Micardis (telmisartan) 80mg or losartan 100mg. To ensure blood pressure control in the two patient groups, other non-ARB treatments (hydrochlorothiazide or a calcium channel blocker) were added, if needed.
No significant difference in blood pressure control or number of adverse events was observed between the two treatment groups.(1)
After treatment of one year, 24 hour protein excretion measured by spot protein to creatinine ratio was reduced by 29% with Micardis (telmisartan) vs. 20% with losartan (p= 0.0284).(1)
At baseline proteinuria was similar for both groups. The change from baseline after 12 months (log transformed Urinary Protein creatinine ratio) was 0.71 for Micardis (telmisartan) vs. 0.80 for losartan (p=0.0284)(1) [Micardis (telmisartan) 0.71 (95% CI; 0.66, 0.77) vs. losartan 0.80 (95% CI; 0.74, 0.87)].(1)
Proteinuria (high levels of protein in the urine) is a very important signal for disease severity in diabetic nephropathy and is also considered a relevant cardiovascular risk factor. Renal outcomes trials have shown that reductions in proteinuria of >30% at six months are strongly linked to slowed progression to end-stage kidney disease and reduced cardiovascular events.(2)
AMADEO* concludes a series of studies which are part of an
extensive ongoing trial program, with several clinical studies, as
