Primary Outcome Measures:
  • change from baseline to end of 8 week treatment in sitting diastolic blood pressure [ Time Frame: 8 week from baseline ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • change from baseline to end of 2,4 week treatment in sitting diastolic blood pressure [ Time Frame: 2, 4 week from baseline ] [ Designated as safety issue: Yes ]
  • change from baseline to end of 2,4,8 week treatment in sitting systolic blood pressure [ Time Frame: 2,4,8 week from baseline ] [ Designated as safety issue: Yes ]
  • responders after end of 8 week treatment(portion of DBP<90mmHg or the difference from baseline and end of 8 week treatment>10mmHg [ Time Frame: 8 week from baseline ] [ Designated as safety issue: Yes ]

Detailed Description:

Fimasartan (BR-A-657-K), a selective blocker of AT1 receptor subtype, showed the rapid and potent antihypertensive effect in many hypertensive models. Phase I study, Fimasartan (BR-A-657-K) 20mg ~ 480mg single dosing with healthy subjects, demonstrated that the Fimasartan (BR-A-657-K) was very safe and well tolerated. Another phase I study, Fimasartan (BR-A-657-K) 120mg and 360mg dosing for 7 days, also showed that Fimasartan (BR-A-657-K) was safe and tolerable though one temporal adverse event was observed in high dose.

A randomized, double-blind, placebo-controlled, parallel grouped, clinical study will be conducted to evaluate the antihypertensive efficacy and tolerability and to determine adequate antihypertensive dosage of Fimasartan(BR-A-657-K) in patients with mild to moderate essential hypertension.

Approximately 182 patients will be enrolled over 12 months in 8 centers nationwide.

After 2 weeks of placebo run-in period, all subjects will be randomized into one of the following 5 groups. Subjects will take test/control drug for 8 weeks of treatment period. If subjects take any antihypertensive medications before screening, the subjects will have 1 week of wash-out period.

Group I : Placebo, Group II : Fimasartan 20 mg, Group III: Fimasartan 60 mg, Group IV : Fimasartan 120 mg, Group V : Fimasartan 240 mg,
