About this study

Official title: Effect of Natural S-equol on Blood Pressure and Vascular funtion-a Six-month Randomized, Double-blind and Placebo-controlled Trial Among Equol Non-producers of Postmenopausal Women With Prehypertension or Untreated Stage 1 Hypertension

We propose to perform a 24-week randomized, double-blind a placebo-controlled trial among 207 non-equol producing postmenopausal women with prehypertension to examine the effectiveness of equol (10mg and 20mg/d) on 24h ambulatory blood pressure, vascular function and other cardiovascular risks (lipid profile, glycemic control and inflammatory biomarkers) and explore the optimal dosage of equol.

Questions about this trial

What is this clinical trial studying?

A study testing High equol group and Low equol group in people with Hypertension, run by Chinese University of Hong Kong.

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 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

The record says: status not confirmed, as of the sponsor's last update on 5 Aug 2015. Status can change between updates, so confirm with the study contact before making plans.

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.

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.

What does the primary outcome measure?

Ambulatory blood pressure (time frame: 24 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02515682, which also lists 1 linked publication.

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?
