About this study
Official title: Effect of ALT-711 in Combination With Fixed-Dose Hydrochlorothiazide Therapy on Systolic Blood Pressure in Hypertensive Patients
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).

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing alagebrium chloride (ALT-711) in people with Hypertension, run by Synvista Therapeutics, Inc at 1 site in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: stopped early, as of the sponsor's last update on 8 Feb 2010. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study was stopped early. Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00089713, which also lists 10 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 8 Feb 2010; AzTrials last refreshed its copy on 8 Nov 2026.
