Survival Evaluation in Japan Trial<br />

Ogihara T et al. Hypertension. 2008;51:1-6


Rationale <strong>of</strong> the Study<br />

ARB ARBs and d CCB CCBs are th the most t widely id l used d<br />

antihypertensive drugs in the world.<br />

The incidences <strong>of</strong> stroke and coronary artery diseases,<br />

however, are significantly different in Japan<br />

compared to Europe and the USA.<br />

The CASE-J Study was designed as a large-scale<br />

clinical trial to evaluate the efficacy <strong>of</strong> <strong>Candesartan</strong> and<br />

<strong>Amlodipine</strong> for reducing the incidences <strong>of</strong> cardiovascular<br />

morbidity and mortality in Japanese patients.


Outline <strong>of</strong> the study<br />

Objectives : A comparison <strong>of</strong> the efficacies <strong>of</strong> ARB<br />

and CCB for reducing cardiovascular<br />

mortality t lit and d morbidity bidit<br />

Subjects : High-risk hypertensive patients<br />

Test drugs : <strong>Candesartan</strong> and <strong>Amlodipine</strong><br />

Follow-up period: 3.0 years or more<br />

Study period : September 2001 to December 2005<br />

Study y design g : Open p Label Randomized Controlled Trial<br />

Evaluation : The PROBE method

Summary<br />

<strong>Candesartan</strong> and <strong>Amlodipine</strong> equally reduced the<br />

number <strong>of</strong> CV events in high-risk hypertensive patients<br />

under strict BP control (< 140/80 mmHg) mmHg).<br />

<strong>Candesartan</strong> suppressed the progression <strong>of</strong> renal<br />

dysfunction in patients with renal impairments<br />

impairments.<br />

<strong>Candesartan</strong> decreased total mortality in obese patients.<br />

A significantly larger decrease in the left ventricular mass<br />

index values was observed in the <strong>Candesartan</strong> group<br />

than in the <strong>Amlodipine</strong> group group.<br />

<strong>Candesartan</strong> prevented new-onset diabetes.


Conclusions<br />

<strong>Candesartan</strong> and <strong>Amlodipine</strong> equally reduce the number<br />

<strong>of</strong> CV events in high-risk hypertensive patients under<br />

strict BP control.<br />

<strong>Candesartan</strong> is more beneficial than <strong>Amlodipine</strong> p for<br />

hypertensive patients with chronic kidney disease or<br />

obesity, and may be preferable for patients with<br />

metabolic syndrome.

Background<br />

ACE ACE-inhibitors i hibit iimprove clinical li i l outcome t iin patients ti t<br />

with coronary artery disease (CAD).<br />

HHowever, it still till remains i uncertain t i whether h th<br />

Angiotensin II receptor blockers (ARB) reduce the risk<br />

<strong>of</strong> cardiovascular events.


Hypothesis<br />

<strong>Candesartan</strong>-based pharmacotherapy reduces the<br />

cardiovascular events compared to non non-ARB-based<br />

ARB based<br />

standard pharmacotherapy<br />

in angiographically documented CAD patients with<br />

hypertension.

Summary<br />

IIn comparison i with i h standard d d therapy, h<br />

<strong>Candesartan</strong>-based therapy<br />

• reduced the incidence <strong>of</strong> MACE by 11%, while not<br />

statistically significant.<br />

• reduced the incidence <strong>of</strong> new-onset DM by 63%.<br />

• caused a lower incidence <strong>of</strong> drug-related g AE.<br />

• significantly reduced the incidence <strong>of</strong> MACE by 21%<br />

in patients with impaired renal function.


Conclusion<br />

• <strong>Candesartan</strong>-based therapy produced comparable<br />

effects to Non-ARB-based standard therapy and was<br />

well tolerated in CAD patients with hypertension.<br />

hypertension<br />

• Furthermore Furthermore, candesartan significantly reduced the<br />

incidence <strong>of</strong> new-onset DM.<br />

• The present study provides evidence to support the<br />

rationale for candesartan candesartan-based based therapy in CAD<br />

patients,particularly in those with chronic kidney<br />

di disease.


Conclusions<br />

<strong>Candesartan</strong> and <strong>Amlodipine</strong> equally reduce the<br />

number <strong>of</strong> CV events in high-risk hypertensive<br />

patients under strict BP control.<br />

<strong>Candesartan</strong>-based therapy py pproduced comparable p<br />

effects to Non-ARB-based standard therapy and was<br />

well tolerated in CAD patients p with hypertension.<br />

yp<br />

<strong>Candesartan</strong> is more beneficial than <strong>Amlodipine</strong> and<br />

ACEI for hypertensive patients with chronic kidney<br />

disease or obesity, and may be preferable for<br />

patients with metabolic syndrome syndrome.
