NCT00135551

Brief Summary

A number of major clinical trials have demonstrated the clinical benefits of lowering blood pressure and have indicated that a majority of patients with hypertension will require more than one drug to achieve optimal blood pressure control. There is little data showing which antihypertensive combination best protects patients from cardiovascular events and which best achieves the target blood pressure with the fewest adverse events. The COPE trial is planned to investigate, in patients with hypertension, which combination of the antihypertensive drugs, angiotensin receptor blockers, β-blockers or thiazide diuretics in addition to a long-acting calcium antagonist, benidipine hydrochloride, is superior to achieve the targeted blood pressure and prevent cardiovascular events with the fewest adverse drug effects.

Eligibility Criteria

Age40 Years - 85 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Outpatients who are required a combination therapy with sitting systolic blood pressure ≥ 140 mmHg or diastolic blood pressure ≥ 90 mmHg.
  • Outpatients aged over 40 years and less than 85 years (inclusive), regardless of sex.
  • Previously untreated patients or patients who are on other therapy, which can be converted to 4mg of benidipine.
  • Patients who can be treated with benidipine, angiotensin receptor blockers, β-blockers, and thiazide diuretics.

You may not qualify if:

  • Seated systolic blood pressure ≥ 200 mmHg or seated diastolic blood pressure ≥ 120 mmHg.
  • Secondary hypertension.
  • Type I diabetes mellitus or type 2 diabetes on insulin treatment.
  • History of cerebrovascular disorder, myocardial infarction, angina pectoris, coronary angioplasty or coronary artery bypass graft surgery within 6 months prior to enrolment in the study.
