About this study

Official title: Efficacy and Safety of Anticoagulant on Early Prevention of Post-STEMI Left Ventricular Thrombus: an Open, Prospective, Randomized and Multi-centers Trial.

Left ventricular thrombus is a common complication subsequent to ST-segment elevation myocardial infarction (STEMI) that related to increased embolic events. This study aims to assess the efficacy and safety outcomes of Rivaroxaban on the prevention of post-STEMI left ventricular thrombus.

Read the detailed description

According to the newest JAMA review, the incidence of left ventricular thrombus (LVT) in the ST-segment elevation myocardial infarction (STEMI) infarction patients is 15%, with particularly 25% in the anterior STEMI patients. Therefore, it is very necessary to find to strategy to prevent to the left ventricular thrombus formation in STEMI patients.

In the 2013 AHA STEMI guidelines and 2014 AHA stroke prevention guidelines, it was advised to add warfarin to traditional double anti-platelet therapy in anterior STEMI with INR between 2.0 to 2.5. However, date from 2015 to 2017 have suggested potentially less demonstrable benefits with warfarin in the prevention of LV thrombus. In an observational study of 460 patients with anterior STEMI and apical akinesis or dyskinesis who underwent PCI, Le May et al 30 compared outcomes in patients who did and did not receive warfarin. Compared with patients in the no warfarin group, patients treated with warfarin had higher rates of composite all-cause mortality, stroke, re-infarction, and major bleeding within 180 days (15% vs 5%), death (5% vs 2%), stroke (3% vs 0.3%), and major bleeding(9% vs 2%). There were no differences in LV thrombus formation between groups. Another observational study undertaken by Shavadia et al reached a similar conclusion that prophylactic warfarin use was not associated with lower composite end point of recurrent ischemia, stroke/transient ischemic attack/systemic embolism, or all-cause death but was associated with higher major bleeding rates at 1 year (2.5% vs 1.2%). The secondary analysis of the Harmonizing Outcomes With Revascularization and Stents in Acute Myocardial Infarction (HORIZONS-AMI) trial found the same results.

On the other hand, addition of Rivaroxaban to double anti-platelet therapy is very likely to be proved beneficial in STEMI patients. In the Anti-Xa Therapy to Lower Cardiovascular Events in Addition to Standard Therapy in Subjects With Acute Coronary Syndrome 2-Thrombolysis in Myocardial Infarction 51 (ATLAS ACS 2-TIMI 51) trial, the researchers found that the addition of reduced doses of rivaroxaban to double anti-platelet therapy after STEMI reduced a composite of cardiovascular death, MI, or stroke from 10.6% to 8.4% (P = .02) but increased major bleeding (2.2% vs 0.6%; P < .001) and intracranial hemorrhage (0.6% vs 0.1%; P = .02). However, the 2.5-mg twice-daily dose of rivaroxaban when added largely to a background of aspirin and clopidogrel significantly reduced the rate of all-cause mortality vs placebo. What's more, in 2017 the Cardiovascular Outcomes for People Using Anticoagulation Strategies (COMPASS) trial demonstrated that rivaroxaban (2.5mg twice daily) reduced the risk of ischemic events compared with placebo on a back ground of low-dose aspirin in abroad population of patients with stable coronary or peripheral artery disease. Therefore, using low dose rivaroxaban (2.5mg twice daily) to prevent post-STEMI LVT is rather promising.

This study aims to evaluate the therapeutic efficacy and safety of rivaroxaban on the prevention of post-STEMI LVT.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. The accumulative percentage of LVT formation at 24 weeks

    The LVT resolve will be determined monthly by follow-up imaging examination (CMR or TTE). The percentage of LVT resolve at 24 weeks will be calculated for each group.

    Measured: at 24 weeks

  2. Bleeding events (ISTH criteria) through the study, an average of 24 weeks

    Bleeding events will be classified by the ISTH criteria. Major bleeding is defined using ISTH criteria as clinically over bleeding that is associated with: 1. A fall in hemoglobin of 2g/dL or more or 2.A transfusion of 2 or more units of packed red blood cells or whole blood, or 3.A critical site: intracranial, intraspinal, intraocular, pericardial, intra-articular, intramuscular with compartment syndrome, retropertioneal, or 4. A fatal outcome. All bleeding events will be documented through the study, an average of 24 weeks.

    Measured: through the study completion, an average of 24 weeks.

Secondary outcomes (1)

  1. Composite major adverse events through the study, an average of 24 weeks

    The incidence of a composite adverse events, including all-cause death, recurrent myocardial infarction, ischemic stroke and other systemic embolism through 24 weeks will be calculated for each group.

    Measured: through the study completion, an average of 24 weeks.

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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Jun Pu, Professor (08602168383164, pujun310@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The accumulative percentage of LVT formation at 24 weeks (time frame: at 24 weeks). The study lists 2 primary outcomes in all. 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 NCT03786757, which also lists 16 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 26 Dec 2018.
