Efficacy and Safety of Fimasartan Alone or Combined With HCTZ in Mexican Patients With Essential Hypertension

• Status: Completed
• Trial end date: 2014-02-01
• Target enrollment: 0
• Participant gender: All

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.

• Secondary hypertension.

• Impossibility to safely undergo a two week washout period from previous treatment prior to assignment to the study treatment, if applicable and according to the principal investigator´s judgment.

• Systemic diseases such as renal dysfunction (creatinine ≥1.5 time above the upper limit of the reference range), gastrointestinal disorders, hematological disorders or liver dysfunction (AST y/o ALT ≥1.5 times the upper limit of the reference range), capable to affect the absorption, distribution, metabolism and excretion of the study drug.

• History of alcohol or addictive substance abuse.

• Subjects participating in other clinical studies or who have participated in other study within the 6 months prior to screening.

• Any other reason which in the investigator's opinion might contraindicate the participation of a subject in the study.
