About this study
Official title: Anticoagulant Regimens Given to Achieve Thrombus Regression and Reduce Clinical Outcomes Among Patients With Non Device-related Intra-cardiac Thrombus: a Randomized Assessment Under Direct Oral Anticoagulant and Vitamin-k Antagonist Therapy
Left ventricular thrombus is found in 10 to 25% of patients with impaired left ventricular function following ST-segment elevation myocardial infarction and up to 20% in dilated cardiomyopathy in observational studies. Likewise, the incidence of atrial thrombus among atrial fibrillation patients treated by vitamin K antagonist (VKA) is between 0.25% and 7%. Despite anticoagulant therapy, intra-cardiac thrombus remains a severe complication associated with a high risk of systemic embolism and subsequent mortality but also bleeding events related to the anticoagulation therapy. The class of non-vitamin K antagonist direct oral anticoagulant (DOA) has emerged in the last decades and has systematically surpassed VKA in the different clinical settings by providing at minimum a similar efficacy and a better safety profile. In the absence of randomized study in the specific clinical setting of intracardiac thrombus, international Guidelines recommend, on the basis of expert opinion, the use of VKA for at least 3 to 6 months in case of left ventricular thrombus and there is no specific recommendation for thrombus management from other cardiac localizations.
In comparison to VKA, the easier management and the large evidence of better safety of DOA make it an interesting anticoagulant strategy. Data for left ventricule thrombosis treatment are limited and only supported by observational cohorts. However, these recent cohorts have shown promising data in this indication reporting similar thrombus regression following DOA in comparison to VKA and similar ischemic outcomes although no head-to-head comparison would be powered.
As a consequence, the multicentric randomized ARGONAUT trial aims to confirm these results and evaluate the impact of DOA compared to VKA on thrombus regression and clinical outcomes among patients with intracardiac thrombus, regardless of the thrombus localization and any underlying heart disease.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Vitamin K antagonistDrug
VKA study medications (Warfarin, Fluindione and Acenocoumarol) will be prescribed and supplied in the usual setting of patient care with respect of the international guidelines and recommended dose protocols and will not be specifically supplied for the trial. Anticoagulant treatment will be prescribed for 6 months. The recommended INR target will be [2-3] and [2-2.5] for patients treated with concomitant antiplatelet therapy. Biological monitoring will be performed at discretion of physicians as usual care.
Direct oral anticoagulantDrug
DOA study medications (Apixaban, Rivaroxaban and Dabigatran) will be prescribed and supplied in the usual setting of patient care and will not be specifically supplied for the trial. The usual doses of DOA will be prescribed: dabigatran 150mg twice a day, apixaban 5mg twice a day and rivaroxaban 20mg once a day. The adjusted doses (dabigatran 110mg twice a day, apixaban 2.5mg twice a day and rivaroxaban 15mg once a day) will be prescribed according to clinical practice treatment guidelines.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Vitamin K antagonist and Direct oral anticoagulant in people with Intracardiac Thrombus and STEMI, run by Centre Hospitalier Universitaire de Nīmes at 35 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 5 inclusion and 15 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: under way, not looking for participants, as of the sponsor's last update on 17 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 35 sites in France, Reunion. 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 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?
This study is still under way. Results are not available in the source record yet.
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?
Net clinical benefit of DOA in comparison to VKA in patients with intra-cardiac thrombus (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 NCT05825573, 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 17 Feb 2026.
