A Phase IIa, Double-Blind, Randomized, Parallel-Design, Four-Week Study to Investigate the Efficacy and Safety of Two Different Doses of the Renin-Inhibitor SPP635 Once Daily in Type II Diabetic Patients With Mild to Moderate Hypertension and Albuminuria

This is a phase II a, double-blind, randomized, parallel-design, four-week study to investigate the efficacy, safety and tolerability of two different doses of SPP635 in type II diabetic patients with mild to moderate hypertension and albuminuria.
The total study duration for patients completing the entire study will be approximately 7 weeks including a 2 weeks Screening Phase, 1 week Wash-out Phase, 4 week Treatment Phase and 1 week Follow-up Phase.
All treatments other than certain antihypertensive drugs (which are to be washed-out) with an effect on BP and all antidiabetic treatments must be kept at stable dose during the whole study.
A maximum of 50 patients in total is planned to be enrolled.

Aliskiren Reduces Blood Pressure and Suppresses Plasma Renin Activity in Combination With a Thiazide Diuretic, an Angiotensin-Converting Enzyme Inhibitor, or an Angiotensin Receptor Blocker

Thiazide diuretics, angiotensin-converting enzyme inhibitors, and angiotensin receptor blockers all cause reactive rises in plasma renin activity. We hypothesized that renin inhibition with aliskiren would prevent this reactive rise and also enhance blood pressure lowering. In 3 open-label studies in which blood pressure was assessed with ambulatory measurement, aliskiren was administered to patients with mild-to-moderate hypertension in combination with hydrochlorothiazide (n=23), ramipril (n=21), or irbesartan (n=23). In the diuretic combination study, the addition of 25 mg of hydrochlorothiazide to 150 mg of aliskiren daily for 3 weeks significantly lowered daytime pressure, compared with aliskiren monotherapy (systolic/diastolic mean change from baseline [SEM]: daytime: −18.4 [2.1]/ −10.6 [1.7] versus −10.4 [1.8]/−5.8 [1.4]; nighttime: −15.6 [2.7]/−8.1 [1.8] versus −8.8 [2.9]/−5.0 [2.2]). In the angiotensin-converting enzyme inhibitor combination study, the addition of 75 or 150 mg of aliskiren to 5 mg of ramipril alone for 3 weeks further lowered both daytime and nighttime pressures compared with ramipril monotherapy (daytime: −10.5 [2.9]/−8.1 [2.1] and −14 [3.7]/−8.7 [2.3] versus −6.1 [2.4]/−5.9 [1.5]; nighttime: −8.1 [2.6]/−5.3 [2.4] and −9.6 [3.4]/−5.3 [2.4] versus −2 [2.3]/−0.7 [2.2]). In the angiotensin receptor blocker combination study, the addition of 75 or 150 mg of aliskiren to 150 mg of irbesartan alone, for 3 weeks, resulted in significantly lower nighttime pressures compared with irbesartan monotherapy (daytime: −14.8 [2]/−8.2 [1.3] and −13.3 [1.6]/−6.8 [0.9] versus −11.4 [1.6]/−6.5 [1.1]; nighttime: −16.1 [2.4]/−8.6 [1.7] and −13.2 [2.7]/−7.2 [1.9] versus −9.0 [2.5]/−4.7 [1.9]). Aliskiren (150 mg) alone significantly inhibited plasma renin activity by 65% ( P <0.0001). Ramipril and irbesartan monotherapy caused 90% and 175% increases in plasma renin activity, respectively. By contrast, when aliskiren was coadministered with hydrochlorothiazide, ramipril, or irbesartan, plasma renin activity did not increase but remained similar to baseline levels or was decreased (combination therapy versus untreated; median [interquartile range]; aliskiren and hydrochlorothiazide: 0.4 [0.2 to 1.1] versus 0.7 [0.5 to 1.3]; ramipril and aliskiren: 0.5 [0.3 to 0.9] versus 0.6 [0.5 to 0.8]; irbesartan and aliskiren: 0.4 [0.2 to 0.9] versus 0.6 [0.4 to 0.9]). These results suggest that renin inhibition with aliskiren in these combinations increases renin-angiotensin system suppression, improves 24-hour blood pressure control, and may ultimately provide better end-organ protection in patients with hypertension.

Blood Pressure Lowering in Essential Hypertension With an Oral Renin Inhibitor, Aliskiren

Q1 · MEDICINE

Article

Author: Jensen, Chris ; Stanton, Alice ; Nussberger, Juerg ; O'Brien, Eoin

Inhibition of the first and rate-limiting step of the renin-angiotensin system has long been an elusive therapeutic goal. Aliskiren, the first known representative of a new class of completely nonpeptide, orally active, renin inhibitors, has been shown to inhibit the production of angiotensin I and II in healthy volunteers and to reduce blood pressure (BP) in sodium-depleted marmosets. The aim of this randomized, double-blind, active comparator trial study was to assess the BP-lowering efficacy and safety of aliskiren. Two hundred twenty-six patients, 21 to 70 years of age, with mild to moderate hypertension, were randomly assigned to receive 37.5 mg, 75 mg, 150 mg, or 300 mg aliskiren or 100 mg losartan daily for 4 weeks. Dose-dependent reductions in daytime ambulatory systolic pressure (mean change, mm Hg [SD of change]; −0.4 [11.7], −5.3 [11.3], −8.0 [11.0], and −11.0 [11.0], P =0.0002) and in plasma renin activity (median change % [interquartile range]; −55 [−64, −11], −60 [−82, −46], −77 [−86, −72], and −83 [−92, −71], P =0.0008) were observed with 37.5, 75, 150, and 300 mg aliskiren. The change in daytime systolic pressure with 100 mg losartan (−10.9 [13.8]) was not significantly different from the changes seen with 75, 150, and 300 mg aliskiren. Aliskiren was well tolerated at all doses studied. This study demonstrates that aliskiren, through inhibition of renin, is an effective and safe orally active BP-lowering agent. Whether renin inhibition results in protection from heart attack, stroke, and nephropathy, similar to angiotensin-converting enzyme inhibition and angiotensin receptor blockade, needs to be researched.
