Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 21 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Subject previously participated in the ALERTS study and currently has either a Guardian System IMD plus IS-1 lead or IS-1 lead still in place and hasn't developed exclusion criteria.
  • Subject (men or women) is at least 21 years of age.
  • Women of childbearing age must have a negative pregnancy test or confirmation of one of the following:

Who cannot join

  • In the investigator's opinion, subject lacks ability to respond appropriately to alarms, e.g., illiteracy, poor memory or cognitive function, dementia or other condition affecting memory function, etc.
  • Known compromised tissue at the site of lead implantation in the apex of the right ventricle, e.g., prior infarct affecting the RV apex location.
  • A permanent pacemaker or ICD is already in place or the patient is indicated for ICD or pacemaker implantation based on the guidelines published by the American College of Cardiology as Class I and IIa recommendations. Class IIb recommendations are at the investigator's discretion.

  • Subject has left ventricular hypertrophy evidenced by EKG criteria.
  • Subject has any condition preventing the subcutaneous implantation of the Guardian System in a left pectoral pouch, such as:
  • superior vena cava thrombosis,
  • subcutaneous tissue deemed inappropriate for the procedure

  • Subject has had a hemorrhagic stroke or transient ischemic attack (TIA) in the past 6 months.
  • Subject has other severe diseases, such as cancer or refractory congestive heart failure, associated with limitation of life expectancy (less than 1 year), which may lead to inadequate compliance to the protocol or confusing data interpretation.
  • Subject has clinical conditions such as heart diseases, difficult-to-control blood pressure, difficult-to-control insulin-dependent diabetes or serious prior infections attributed to the diabetes, or others that, at the investigator's discretion, could seriously affect the subject's current clinical condition during study procedures.

About this study

Official title: ALERTS Continued Access Study- IDE G060259 Supplement

This Continued Access IDE Study includes a subset of former ALERTS trial (NCT00781118) patients and provides performance data for a refined Guardian implantable medical device (AMSG3-E) with a new battery designed to extend device longevity.

Read the detailed description

This Continued Access IDE Study is a prospective, non-randomized, multi-center (up to 25 sites) study designed to provide performance assessment of a refined Guardian implantable medical device (AMSG3-E) through controlled access of a replacement Guardian System to a subset of former ALERTS patients while waiting for FDA approval of the AMSG3-E. The AMSG3-E contains a drop-in replacement battery designed to extend the life of the implant to potentially exceed the previous 3-years implant life. Eligible patients will include those that exited the ALERTS study and chose to leave the device and/or lead in place. Eligible patients must also continue to meet ALERTS inclusion criteria and not have developed any exclusion criteria since exiting the ALERTS study.

What participants receive

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

  • AngelMed Guardian SystemDevice

    The AngelMed Guardian System detects potential ongoing ACS events, characterized by sustained ST segment changes, and alerts the patient to seek medical attention for those potential ACS events. The Guardian System is indicated as an adjunct to patient recognized symptoms.

Study groups in NCT04316481
Study groupRoleWhat they receive
AngelMed Guardian SystemOtherAll eligible subjects will have the AngelMed Guardian System implanted with alerting features turned ON; receive an external device which provides additional alerting; and receive training on system use.
Receives: Device: AngelMed Guardian System

What is being measured

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

  1. Rate of Serious Adverse Events (SAE)

    Annual rate of SAEs related to the device or procedure

    Measured: 5 years

Timeline

From the start of the study to its completion; the mark is today. Estimated dates are the sponsor’s plan.

  1. First posted20 Mar 2020
  2. Study start22 Sep 2020
  3. Primary completion20 Jan 2022
  4. Study completion20 Jan 2022

Why it stopped: FDA Approval was received for the Model AMSG3-E IMD and therefore commercial implants could be started. There was no longer any need to implant under the CAS. CAS patients were transitioned to commercial patients.

Questions about this trial

What is this clinical trial studying?

A study testing AngelMed Guardian System in people with Acute Coronary Syndrome, run by Angel Medical Systems at 1 site in United States.

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 22 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: stopped early, as of the sponsor's last update on 3 Jun 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 United States. 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.

Are results available for this study?

The study was stopped early (reason given: FDA Approval was received for the Model AMSG3-E IMD and therefore commercial implants could be started. There was no longer any need to implant under the CAS. CAS patients were transitioned to commercial patients.). Results are not available in the source record.

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?

Rate of Serious Adverse Events (SAE) (time frame: 5 years). 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 NCT04316481, which also lists 3 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 3 Jun 2022.
