Trial summary

Atrial fibrillation remains a major cause of morbidity following cardiac surgery with cardiopulmonary bypass. Many mechanisms have been implicated. Among then, adenosine, a strong endogenous vasodilating agent has been involved in cardiac surgery-induced atrial fibrillation, via A2A receptors modulation. Read more about this study

About this study

Atrial fibrillation remains a major cause of morbidity following cardiac surgery with cardiopulmonary bypass. Many mechanisms have been implicated. Among then, adenosine, a strong endogenous vasodilating agent has been involved in cardiac surgery-induced atrial fibrillation, via A2A receptors modulation.

The effects of caffeine on the inducibility of atrial fibrillation are actually well-known, leading then to a significant reduction of atrial fibrillation. Moreover, a recent clinical study has demonstrated that coffee drinking was inversely associated with total and cause-specific mortality.

The investigators therefore examined the preventive effects of oral caffeine on valvular surgery with cardiopulmonary bypass-induced atrial fibrillation. The investigators also evaluated prospectively the influence of caffeine on adenosine plasma levels and A2A adenosine receptors modulation.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing citrate of caffeine in people with Atrial Fibrillation, run by Assistance Publique Hopitaux De Marseille at 1 site in France.

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 10 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 14 Mar 2017. 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 France. 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. 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 this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

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 is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Decrease of 50 % of the incidence of atrial fibrillation (time frame: 24 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 NCT01999829, 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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Mar 2017.
