About this study

Official title: Hellenic Anglo Research Into Morning Or Evening Antihypertensive Drug deliverY Trial

A randomised crossover trial of anti-hypertensive medication dosing regimen in effective blood pressure control.

To investigate whether there is a difference in 24 hour blood pressure (BP) control when antihypertensive medications are taken in the morning compared with the evening.

Read the detailed description

The identification of any significant difference could lead to more effective therapeutic management of arterial hypertension, which in turn would result in a reduced cardiovascular burden, lower costs and a better quality of life for hypertensive patients.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Anti-hypertensive Medication - in people with Hypertension, run by Imperial College London at 2 sites in 2 countries.

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 5 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: finished, as of the sponsor's last update on 8 Mar 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in Greece, United Kingdom. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 8 Mar 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Changes in 24 Hour Systolic Blood Pressure (time frame: 6 months). 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 NCT01669928, which also lists 8 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 Mar 2021.
