Phase 3: testing Continuous DOAC therapy for Atrial Fibrillation

REACT-AF is a multicenter prospective, randomly assigned, open-label, blinded endpoint (PROBE design), controlled trial comparing the current Standard Of Care (SOC) of continuous Direct Oral Anticoagulation (DOAC) use versus time-delimited (1 month) DOAC guided by an AF-sensing Smart Watch (AFSW) in participants with a history of paroxysmal or persistent Atrial Fibrillation (AF) and low-to-moderate stroke risk.

Not a traditional drug phase: CT coronary angiography for Atrial Fibrillation (AF)

The goal of this watch-and-measure (no experimental treatment required) study is to better understand the role of measuring troponin (a protein measured by a blood test) and coronary imaging in patients presenting with rapid atrial fibrillation (AF) The main questions this study aims to answer are: 1. Are patients with a fast, irregular heartbeat (rapid AF) and damage to the heart (myocardial injury) more likely than those without damage to the heart to have blocked heart arteries (obstructive coronary artery disease) 2.

Not a traditional drug phase: VERAFEYE Anatomic Guidance System for Atrial Fibrillation

The objective of the study is to collect data on the use of the VERAFEYE Anatomical Guidance System in adult patients indicated to undergo a catheter ablation procedure for the treatment of Atrial Flutter (AFL), paroxysmal AF (PAF) or persistent AF (perAF). The study will collect specific information on management of AFL/AF ablation procedures with the commercial VERAFEYE Anatomical Guidance System including but not limited to acute procedural success , and how the VERAFEYE Anatomical Guidance System is used overall.

Not a traditional drug phase: Concomitant pulsed field ablation (PFA) and left atrial appendage closure (LAAC) during one interventional case for Atrial Fibrillation (AF)

The OPTION-EMEA post-market study is intended to gather real world clinical data for patients undergoing AF ablation with the FARAPULSE™ Pulsed Field Ablation (PFA) System and subsequent left atrial appendage closure (LAAC) with a WATCHMAN FLX™ Pro or WATCHMAN FLX device during one treatment case. The study will include patients that are clinically indicated for atrial fibrillation (AF) ablation using the FARAPULSE PFA System and for left atrial appendage closure (LAAC) treatment using a WATCHMAN FLX Pro or WATCHMAN FLX device as part of the patient's standard of care determined by their doctor's medical judgement.

A Study of Varipulse Catheter in Participants With Paroxysmal Atrial Fibrillation Under Optimized Sedation

The main purpose of the study is to assess how well the standard ablation procedure (Varipulse Catheter) works over long term when used with different types of anesthesia in participants with symptomatic paroxysmal atrial fibrillation (PAF, irregular heartbeat that comes and goes on its own, causing noticeable symptoms like a racing heart, or shortness of breath).

Not a traditional drug phase: VARIPULSE Catheter System for Atrial Fibrillation

This study wants to assess how safe VARIPULSE catheter system is for treatment of a heart rhythm disease called persistent atrial fibrillation (PsAF) in participants who are having a catheter ablation procedure (treat heart rhythm disease). This includes isolation of pulmonary vein and superior vena cava (heart veins; pulmonary vein isolation \[PVI\] and superior vena cava isolation \[SVCI\]), with or without another technique called posterior wall isolation (PWI).

Phase 4: testing SGLT2 inhibitors (Dapagliflozin and Empagliflozin) for Atrial Fibrillation

SGLT2 inhibitors improve outcomes in heart failure across the ejection fraction spectrum, but their effect on maintenance of sinus rhythm after rhythm-control therapy is largely unknown. This prospective, single-center, open-label randomly assigned controlled trial evaluates whether an SGLT2 inhibitor started after successful electrical cardioversion reduces recurrence of atrial tachyarrhythmia at 1 month in patients with persistent atrial fibrillation and heart failure with preserved ejection fraction.

Not a traditional drug phase: testing Deep sedation with midazolam and fentanyl or midazolam and remifentanil for Atrial Fibrillation (AF)

Pulsed Field Ablation (PFA) has created a 'paradigm shift' within cardiac electrophysiology and the initial experience demonstrates that PFA is safe, rapid and effective compared to both radiofrequency ablation and cryoablation in atrial fibrillation (AF). Presently, AF ablation procedures in the UK using PFA are routinely performed using general anaesthetic (GA) support requiring an anaesthetist and ODP being present in all procedures.

Not a traditional drug phase: Telerehabilitation for Heart Failure With Preserved Ejection Fraction

Heart failure with preserved ejection fraction (HFpEF) is characterized by typical symptoms of heart failure, structural and functional cardiac abnormalities, and elevated serum levels of N-terminal pro-B-type natriuretic peptide (NT-proBNP), despite preserved left ventricular ejection fraction. Typical symptoms of HFpEF include reduced exercise tolerance, exertional dyspnea, paroxysmal nocturnal dyspnea, and orthopnea.

FAQ: Atrial fibrillation trials

How do I find recruiting Atrial fibrillation clinical trials?

This hub lists 34 recruiting Atrial fibrillation studies from a ClinicalTrials.gov snapshot, rewritten in plain English. Each card links to its NCT record. You can also search the official registry for “atrial fibrillation” at https://clinicaltrials.gov/search?cond=atrial%20fibrillation.

What does a Atrial fibrillation trial page on PlainTrials include?

A phase explainer, a plain-English summary grounded in the brief summary, inclusion/exclusion extracted from the public eligibility block, sponsor name, and any central contact the sponsor published. It is not a match to a trial.

Where are Atrial fibrillation studies located in this snapshot?

Sites that appear on these records include Boston, Massachusetts; Atlanta, Georgia; Houston, Texas; New York, New York; Chicago, Illinois. A city on a record is not a guarantee that the site is taking new patients this week — call the NCT contact.

Can PlainTrials tell me if I qualify for a Atrial fibrillation study?

No. Eligibility is decided by the study team using the protocol, labs, and consent. Our “who it is for” list is a readable extract of public inclusion text only.
