Narrative objectives1 The purpose is to directly compare cardiovascular mortality and morbidity,
incidence of adverse drug reaction, and degree of blood pressure reduction in Japanese hypertensive patients for a combination of angiotensin receptor blockers, beta-blockers or thiazide diuretics in addition to a calcium antagonist, benidipine hydrochloride, with a response-dependent dose titration scheme

Trial characteristics_1 Confirmatory
Trial characteristics_2 Pragmatic
Developmental phase Phase IV

Primary outcomes 1)A composite of fatal and non-fatal cardiovascular events
(1)Sudden death (acute onset and intrinsic death within 24 h)
(2)Fatal or nonfatal stroke (new onset or recurrence)
(3)Fatal or nonfatal myocardial infarction (new onset or recurrence), hospitalization due to unstable angina, new onset of heart failure(Class II, III, or IV), sudden cardiac death
(4)New onset or worsening of peripheral arterial disease
(5)New onset or worsening of renal failure(as indicated by a serum creatinine level that is at least doubled to over 2 mg/dl) serum creatinine >=4.0 mg/dl, renal dialysis or renal transplantation
2)Achievement of target blood pressure (systolic blood pressure <140 mmHg and diastolic blood pressure <90 mmHg)serious and non-serious cardiovascular events
Key secondary outcomes (1) All-cause mortality
(2) Death from cardiovascular events
(3) Fatal and non-fatal cardiovascular events
(4) Hospitalization due to heart failure
(5) New onset of diabetes mellitus
(6) Safety (adverse events and adverse drug reaction)
