About this study

Official title: The Harbinger ICD Patient (HIP) Study

The purpose of this study is to determine how well the device predicts susceptability to potentially lethal ventricular arrhythmias.

Read the detailed description

Sudden cardiac death (SCD) accounts for half of all deaths from cardiovascular causes, with an annual incidence of 1 to 2 deaths per 1000 population. In the United States this translates to between 300,000 to more than 400,000 deaths annually. Results from numerous large, well designed clinical trials have demonstrated the efficacy of the implantable cardioverter-defibrillator (ICD) for improving survival in patients with ischemic heart disease. However, measures used to risk stratify patients, such as left ventricular ejection fraction do not adequately identify those patients who can most benefit from ICD therapy. As a result, many patients who currently receive an ICD do not use the device. In addition, many more patients who could benefit from ICD therapy are outside of current guidelines and do not have access to this life-saving therapy.

This prospective study was intended to determine how well the Harbinger Wedensky Modulation Index (WMI) technique risk stratifies patients into two groups: those needing antiarrhythmic therapy and those who do not need antiarrhythmic therapy.

Questions about this trial

What is this clinical trial studying?

An observational study of Sudden Cardiac Death, run by Harbinger Medical, Inc. at 8 sites in 4 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 1 inclusion and 3 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 22 Nov 2007. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 8 sites in United States, Germany, Norway, Switzerland. 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?

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?

Life Threatening Cardiac Event (death or annotated malignant ventricular arrhythmia detected by ICD and confirmed by cardiologist review) (time frame: Up to two years). 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 22 Nov 2007.
