About this study

Official title: Multicenter Automatic Defibrillator Implantation Trial With Subcutaneous Implantable Cardioverter Defibrillator (MADIT S-ICD)

The MADIT S-ICD trial was designed to evaluate if subjects with a prior myocardial infarction, diabetes mellitus and a relatively preserved ejection fraction of 36-50% will have a survival benefit from receiving a subcutaneous implantable cardioverter defibrillator (S-ICD) when compared to those receiving conventional medical therapy. The trial enrollment was stopped in 2018 due to lower than expected enrollment, all subjects enrolled at that time were followed for approximately 5 years.

Read the detailed description

In this study, subjects were randomized to receive a subcutaneous implantable cardioverter defibrillator or Conventional Medical Therapy (CMT). Randomization was stratified by enrolling site, in a 2:1 (S-ICD:CMT) scheme. Length of follow-up for each subject was dependent on the date of entry into the study, since all subjects were followed to a common study termination date.

What is being measured

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

  1. All-Cause Mortality

    The original study design was event driven with the end date expected to be based on crossing the statistical boundary. The trial enrollment was stopped in 2018 due to lower than expected enrollment, all subjects enrolled at that time were followed for approximately 5 years. The outcomes will be analyzed but are no longer statistically powered for conclusions.

    Measured: Outcome measured timeframe includes all available follow-up. Median 61 (4, 71) months.

Secondary outcomes (2)
  1. All-Cause Mortality in Various Subgroups

    The original study design was event driven with the end date expected to be based on crossing the statistical boundary. The trial enrollment was stopped in 2018 due to lower than expected enrollment, all subjects enrolled at that time were followed for approximately 5 years. The outcomes will be analyzed but are no longer statistically powered for conclusions.

    Measured: Outcome measured timeframe includes all available follow-up. Median 61 (4, 71) months.

  2. Sudden Death

    The original study design was event driven with the end date expected to be based on crossing the statistical boundary. The trial enrollment was stopped in 2018 due to lower than expected enrollment, all subjects enrolled at that time were followed for approximately 5 years. The outcomes will be analyzed but are no longer statistically powered for conclusions.

    Measured: Outcome measured timeframe includes all available follow-up. Median 61 (4, 71) months.

Questions about this trial

What is this clinical trial studying?

A study testing Subcutaneous Implantable Cardioverter Defibrillator in people with Tachycardia and Diabetes Mellitus, run by Boston Scientific Corporation at 49 sites in 7 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 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: finished, as of the sponsor's last update on 22 Aug 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 49 sites in United States, Germany, Israel, Italy, Netherlands and 2 more countries. 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?

Yes. Results are posted in the registry (first posted 22 Aug 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

All-Cause Mortality (time frame: Outcome measured timeframe includes all available follow-up. Median 61 (4, 71) 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 NCT02787785, 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 22 Aug 2024.
