Brief Summary

Fimasartan (FMS) is an AT1 receptor antagonist indicated for once a day administration, currently approved for the treatment of essential hypertension in Corea and Mexico. As the safety and efficacy of FMS was initially demonstrated in Korea only, it was necessary to address the potential for ethnic factors to have an effect on the drug´s efficacy and safety in the Mexican population. To address this need, a cohort of 272 Mexican subjects with grades 1-2 essential hypertension were sequentially treated on a treat to target basis (target: sitting Diastolic Blood Pressure (sDBP) <90 mmHg) with 60 mg FMS once a day (8 weeks), either 120 mg FMS or 60 mg FMS+12.5 mg HCTZ once a day (randomized 4 week treatment period) and 120 mg FMS once a day (during 12 weeks) for a total treatment period of 24 weeks.

Detailed Description

This was a prospective, open, multicentre, 24 week study of subjects with grade 1-2 essential hypertension eligible, according to the participating investigator's clinical judgement, to initial monotherapy.

Consenting, eligible subjects at 13 Mexican participating centers were initially assigned to monotherapy with 60 mg FMS once a day. At treatment week 8, those subjects with a sDBP ≥90 mmHg were randomized to either 120 mg FMS or to 60 mg FMS + 12.5 mg hydrochlorothiazide (HCTZ) once a day during 4 weeks. At treatment week 12, all non-responding subjects were finally assigned to 120 mg FMS + 12.5 mg HCTZ for the remaining 12 weeks of the planned 24 week treatment period. At treatment weeks 8 and 12, those subjects with a sDBP < 90 mmHg remained on their assigned treatment for the rest of the study.

This cohort study was designed to collect information on treatment effect (blood pressure changes from baseline/reference time and treatment response rates), and safety (i.e., incidence and characterization of clinical, laboratory and ECG adverse events); accordingly, subjects were assessed at treatment weeks 4, 8, 12, 16, 20 and 24 in terms of vital signs, clinical laboratory safety parameters, concomitant medications and adverse events. 12-lead ECG recordings were obtained from all subjects both at screening and at treatment week 24 and a subset of 11 subjects underwent both baseline and treatment week 8 24-hour ABPM recordings.
