Summary
Comparison of the combination of amlodipine with an angiotensin receptor blocker or an
angiotensin converting inhibitor, on central arterial blood pressure in patients with
hypertension and additional risk factors. This is a randomised, double-blind, double-dummy,
multicenter study. The duration of active treatment 24 weeks.
Clinical Details
Official title: Efficacy of Sevikar® Compared to the Combination of Perindopril/ Amlodipine on Central Arterial Blood Pressure in Patients With Moderate to Severe Hypertension-
Study design: Allocation: Randomized, Endpoint Classification: Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Treatment
Primary outcome: Change in central systolic blood pressure from baseline (Week 0, Visit 0) to Final Examination (Week 24, Visit 5) using last observation carried forward approach.
Secondary outcome: Changes in systolic and diastolic ambulatory blood pressure (mean of 24h, daytime and night-time)Changes in conventional mean sitting systolic and diastolic blood pressure measurement Incidence and profile of AEs separately by Run-in Phase and by double-blind Treatment Phase Number of responders at Final Examination defined as normalized or a decrease of systolic blood pressure by at least 20 mmHg or diastolic blood pressure by at least 10 mmHg in conventional BP measurements. Number of normalized at Final Examination (defined as blood pressure <140/90 mmHg or <130/80 mmHg in diabetics/chronic kidney disease, in conventional BP measurements. Changes in mean sitting systolic and diastolic blood pressure (BP) measurements from week 12 to Final Exam in patients with stabilized BP (BP is < 140/90 mmHg or < 130/80 mmHg for diabetics/chronic kidney disease) from Week 12 and Week 18. Changes in Central Systolic Blood Pressure from week 12 to Final Examination in patients with stabilised BP (i.e. patients whose BP is < 140/90 mmHg or < 130/80 mmHg for diabetics/chronic kidney disease) between Week 12 and Week 18.
Detailed description:
The study, multi-center balanced, parallel group (two treatment arms), randomized,
double-blind (double-dummy), non-inferiority study is designed to show non-inferiority of
Sevikar® (olmesartan(OM)/amlodipine (AM)) 40/10 mg compared to the combination of
Perindopril (PER) 8 mg plus Amlodipine 10 mg with regard to central systolic blood pressure
lowering effect, using the change from baseline (Week 0) to final examination (Week 24).
Male and female Caucasians aged ≥ 40 years and <80 years with moderate to severe
hypertension, defined by a systolic blood pressure (SBP) ≥ 160 and ≤ 200 or diastolic blood
pressure (DBP) ≥ 100 and ≤ 115 mmHg for untreated patients, SBP ≥ 140 or DBP ≥ 90 mmHg for
insufficiently pre-treated patients and SBP ≥ 130 mmHg or DBP ≥ 80 mmHg for insufficiently
pretreated diabetics chronic kidney disease will be eligible for participation. In
addition,three additional risk factors should be present.
During the course of the study three central blood pressure measurements (at randomization,
at week 12 and at termination) will be performed with SphygmoCor ultrasound method. The
conventional measurements with calibrated tensiometers (Omron) will be performed at each
visit. Ambulatory blood pressure monitoring will be performed at randomisation.
The study starts with a 2-4 week run in phase. AM will be given as open-labelled 5 mg or 10
mg tablets, administered once daily. After randomization during the double-blind phase,
study medication will comprise either OM/AM 40/10 mg or PER 8 mg (2x4 mg) plus AM 10 mg and
will be administered once daily. Furthermore, open-label HCTZ 12. 5 mg and 25. 0 mg will be
provided in tablets and administered once daily according to the treatment schedule.
The primary endpoint is the change in central SBP from baseline (Week 0, Visit 0) to final
examination (Week 24, Visit 5) using Last Observation Carried Forward (LOCF) approach.
The study is conducted in approximately 15 centres in Spain. Depending on the previously
administered drugs the run in phase is up to four weeks (Visits - 2 and -1). Individual
duration of active treatment (after randomization) will last 24 weeks (Visits 0-5). The
total individual duration is 28 weeks.
A total of 518 patients (259 patients/arm) will be needed in the Per Protocol Set (PPS) for
the confirmatory primary analysis using mean change from baseline (Week 0) to Final
Examination assuming a drop out rate of 20% during Run-in Phase a total of 720 patients have
to be screened in order to achieve 576 (288 patients/arm) randomised patients.
Assuming approximately 10% major protocol deviations, a total of 518 patients will remain in
the PPS.
