Primary Prevention of Cardiovascular Disease (CVD) in Pre-diabetic & Pre-hypertensive Subjects
A study testing Metformin+Enalapril+Simvastatin in people with Pre-diabetes and Pre-hypertension, run by Ramathibodi Hospital at 1 site in Thailand.
Trial summary
The purpose of this study is to determine whether treating pre-diabetic \& pre-hypertensive individuals using multiple drugs intervention (anti-hypertensive drugs (i.e., ACEI) plus anti-glycemic drug (i.e., metformin) plus anti-hyperlipidemic drug (statin)) would lower Cardiovascular Disease (CVD) events.

About this study
Official title: Primary Prevention of Cardiovascular Disease in Pre-diabetic & Pre-hypertensive Subjects Using Multiple Risks Reduction Strategy: A Multi-center, Double-blind, Randomized Controlled Trial
The purpose of this study is to determine whether treating pre-diabetic \& pre-hypertensive individuals using multiple drugs intervention (anti-hypertensive drugs (i.e., ACEI) plus anti-glycemic drug (i.e., metformin) plus anti-hyperlipidemic drug (statin)) would lower Cardiovascular Disease (CVD) events.
Read the detailed description
The risks of CVD are not confined to a subset of established "hypertensive" or "diabetic" population, but also increase among those with suboptimal blood pressure and glycemic level, namely "pre-hypertensive" or "pre-diabetic" population. Evidence on the effectiveness of drug interventions to lower CVD events in pre-clinical stage population has been scant.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does the primary outcome measure?
Cardiovascular Events (time frame: 4-year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 2 Jun 2011; AzTrials last refreshed its copy on 8 Nov 2026.
