This study comprises a 3- to 6-week hydrochlorothiazide run in phase, followed by a 12 week double-blind treatment phase, followed by a 2 week single-blind follow-up hydrochlorothiazide treatment phase. The combined total duration of patient participation is approximately 17-20 weeks. Four double-blind treatment groups approximately equal in size (98) will comprise the study population: placebo or various alagebrium dose groups (10, 50, or 150 mg/day).

Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double
Primary Purpose: Treatment
Official Title: Effect of ALT-711 in Combination With Fixed-Dose Hydrochlorothiazide Therapy on Systolic Blood Pressure in Hypertensive Patients
