  • Acute cerebral infarct, as identified by hyperintensity in diffusion-weighted imaging (DWI) of MRI and hypointensity for apparent diffusion coefficient (ADC) b. DWI of MRI showing non-lacunar stroke, defined as a subcortical infarct ≤ 2.0 cm in largest dimension within the territory of the small penetrating cerebral arteries c.

Not ischemic stroke located at specific regions or severe hemorrhagic infarct identified by brain MRI, including: (i.) Large pontine infarct, which more likely belongs to branch artery disease (BAD) (ii.) Anterior choroidal artery infarct (iii.) Internal border zone infarct, represented with rosary-like pattern of lesions between the territories of lenticulostriate artery and superficial branch of middle cerebral artery (MCA) (iv.) Severe hemorrhagic transformation of acute ischemic stroke, which may impede the usage of antiplatelet agents or anticoagulant within 14 days post-stroke per the investigator's judgment

Who cannot join

  • Patients with the following skin related issues that could put patients at risk, interfere with study evaluations, or prevent meeting the requirements of the study:
  • Intolerable, severe skin allergies to the 24-hour Holter monitor or 14-day EZYPRO® or history of severe skin allergies to medical adhesive bandages
  • Any injury, eczema, dermatitis, chromatosis, or abnormality at the skin site where devices are applied
  • Hyperhidrosis
  • Patients who have contraindication to either of the antiplatelet agents which might be used in this study (i.e. aspirin and/or clopidogrel) or to all types of non-vitamin K antagonist oral anticoagulant (NOAC) (due to allergy, mechanical valve replacement, renal insufficient with creatinine clearance [CCr] < 15 ml/min, moderate to severe mitral stenosis, etc.).
  • Patients who are evaluated as Modified Rankin Scale > 4.
Show all 18Show fewer
  • Mental/physical/social condition (including dementia) which could preclude performing efficacy or safety assessments.
  • Patients with following condition or diseases:
  • Medical history of major bleeding impeding usage of antiplatelet agents or NOAC
  • Medical history of brain or other clinically significant neurological/cardiovascular disorders or injuries other than ischemic stroke in the opinion of the investigator
  • Clinically significant or unstable gastrointestinal, renal, hepatic, endocrine, pulmonary, or cardiovascular disease, including not well controlled hypertension, chronic obstructive pulmonary disease, and diabetes that would hinder or interfere participation to the study in the opinion of the investigator
  • Patients who need to receive anticoagulation therapy prior to the screening visit.
  • Patients who meet following conditions:
  • Patients who are scheduled to receive surgery that may have to stop anticoagulation or antiplatelet therapy during the study period
  • Patients who are scheduled to receive neurological or cardiovascular intervention during the trial period
  • Patients who are unable to undergo brain MRI for any reason.
  • Currently participating in another trial or who participated in a previous clinical trial and received any treatment which may interfere the study data within 2 weeks prior to the screening visit.
  • Patients who need to receive long-term (> 21 days) dual antiplatelet therapy or anticoagulant therapy prior to AF detection after study enrollment.

Official title: An Open-label Study to Evaluate the Effectiveness and Safety of EZYPRO® in Atrial Fibrillation Detection in Nearly Embolic Stroke of Undetermined Source (ESUS) Patient

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • EZYPRO® ECG RecorderDevice

    EZYPRO is an ECG monitoring patch designed to enhance the arrhythmia detection rate by applying 14 days in a home setting environment.

Study groups in NCT05089435
Study groupRoleWhat they receive
14-day EZYPRO and 24-hr HolterOtherPatients wear simultaneously 14- day continuous ECG moniter (EZYPRO) and 24-hr Holter monitor.
Receives: Device: EZYPRO® ECG Recorder

What is being measured

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

  1. Afib detected by 24-hour Holter

    Day 1 of the trial, patients will wear simultaneously 24-hour Holter and the trial device, EZYPRO 14-day monitoring patch. After at least 20 hours of Holter, it will be removed and the ECG data will be collected and analyzed for arrhythmia, especially atrial fibrillation. If AF is detected by Holter, patients will be prescribed NOAC; if no AF is detected, patients will be prescribed antiplatelet agents instead.

    Measured: 24 hours

  2. Afib detected by 14-day EZYPRO

    Day 1 of the trial, patients will wear simultaneously a 24-hour Holter, and the trial device, EZYPRO 14-day monitoring patch. 24-hour Holter will be removed first after at least wearing it for 20 hours with the continuant of EZYPRO. Patients have to wear EZYPRO for up to 14 days (the minimum wear time is 10 days). After the patch removal, the ECG data will be analyzed by the sponsor ECG analysis team and provide an ECG report to investigators. Arrhythmias, especially AF, will be presented in the report for further treatment. If AF is detected by EZYPRO and Holter, patients will be prescribed NOAC; if no AF is detected by either one, patients will be prescribed antiplatelet agents instead.

    Measured: 14 days

Secondary outcomes (1)
  1. Skin irritation by EZYPRO patch

    Before wearing 24-hour Holter and EZYPRO, patients' skin condition will be assessed by trial investigators based on Dermal Response Score, FDA-2018-D-3546, on a scale of 0 to 7. Before and after wearing EZYPRO, the skin condition will be assessed at each visit. At each follow-up visit, the skin condition will be assessed as well. The aim of this evaluation is to observe the safety of EZYPRO and confirm if it will help enhance patient compliance.

    Measured: 180 days

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing EZYPRO® ECG Recorder in people with Atrial Fibrillation and Embolic Stroke of Undetermined Source, run by Sigknow Biomedical Co., Ltd. at 1 site in Taiwan.

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 6 inclusion and 18 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: status not confirmed, as of the sponsor's last update on 10 May 2022. 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 Taiwan. 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?

Results are not available in the source record.

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

Contact Nancy Lu (+886227612577 ext. 134, nancy.lu@sigknow.com.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Afib detected by 24-hour Holter (time frame: 24 hours). 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?
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 10 May 2022.
