Information obtained from ClinicalTrials.gov on June 20, 2008 Link to the current ClinicalTrials.gov record.
Condition(s) targeted: Hypertension
Intervention: IRBESARTAN/HYDROCHLOROTHIAZIDE (Drug); irbesartan (Drug)
Phase: Phase 4
Status: Active, not recruiting
Sponsored by: Sanofi-Aventis Official(s) and/or principal investigator(s): Fern Lim, Study Director, Affiliation: Sanofi-Aventis
Summary
Primary:
1. To compare the change in forearm vascular resistance following a 12-week regimen of
irbesartan/hydrochlorothiazide versus irbesartan
2. To assess changes of serum proinflammatory cytokine, markers of cardiovascular risks,
oxidative stress and circulating adhesion molecule including thiobarbiturate acid
reactive substances (TBARS), C-reactive protein (CRP), interleukin 6 (IL-6), and
vascular cell adhesion molecule 1 (VCAM-1).
Secondary:
1. To compare the reduction in office blood pressure following a 12-week regimen of
irbesartan/hydrochlorothiazide versus irbesartan
2. To compare the response rate (defined as office Systolic blood pressure(SBP)/diastolic
blood pressure (DBP) reduce more than 10mmHg from baseline), and BP controlled rate
(defined as SBP<140 mmHg and /or DBP<90 mmHg)
3. To ascertain the safety and tolerability of irbesartan / hydrochlorothiazide versus
irbesartan when administered once daily
4. To determine whether angiotensin II type 1 (AT-1) receptor gene polymorphisms (including
A1166C gene with about 4% of the minor allele frequency in Chinese population and other
single nucleotide polymorphisms with a higher frequency of about 10% of minor allele) is
related to reduction of BP
