About this study

Official title: Dexmedetomidine Versus Adenosine: Electrophysiologic Effects and Therapeutic Use for Terminating Supraventricular Tachycardia

The purpose of this study is to evaluate the efficacy and safety of dexmedetomidine in the acute termination of Supraventricular Tachycardia (SVT).

Read the detailed description

In 2006 the investigator found that dexmedetomidine, an alpha-2 adrenergic agonist with primarily sedative properties, possesses additional anti-arrhythmic properties. So far the investigator has found that dexmedetomidine has the ability to prevent or terminate arrhythmias like atrial ectopic tachycardia (85% success) and junctional ectopic tachycardia (75% success). The most dramatic effect however was observed in the acute termination of reentrant SVT with a success rate of > 96%. More importantly we found that dexmedetomidine terminates SVT without causing any sinus pause or asystole (frequently seen with adenosine) and thus avoiding the feeling of "impending doom". In this study adenosine is being compared head to head with dexmedetomidine in a cross over study, for both safety and efficacy when given for the termination of SVT in the electrophysiology (EP) lab. Additional EP parameters will be measured to elucidate the exact site of dexmedetomidine's mechanism of action.

What participants receive

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

  • DexmedetomidineDrug

    Also called Precedex

    Dexmedetomidine 2 mcg/kg, Intravenous push

  • AdenosineDrug

    Stepwise incremental approach of adenosine starting at 0.2 mg/kg (max 6 mg) followed by 0.3 mg/kg (max 12 mg) if initial dose was unsuccessful

What is being measured

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

  1. Termination of SVT

    Number of participants with SVT Termination within 3 minutes of medication administration

    Measured: Within 3 minutes

Secondary outcomes (3)
  1. Number of Participants With Sinus Pause >2.5 Sec After Termination of SVT

    Evaluation of the number of participants with sinus pause > 2.5 sec, after dexmedetomidine vs. adenosine induced SVT termination

    Measured: 1 minute

  2. Number of Participants With Tachyarrhythmias After Medication Administration

    Number of participants with tachyarrhythmias, including Ventricular (Ventricular Tachycardia \& Fibrillation)and supraventricular (Atrial Flutter \& Fibrillation) after dexmedetomidine vs. adenosine administration

    Measured: 10 minutes

  3. Number of Participants With Hypotension by Non-invasive Cuff in First 10 Minutes After Medication Administration

    Blood pressure changes after dexmedetomidine vs. adenosine. Blood pressure measured by non-invasive cuff prior to medication administration, and then at 1 min, 3 min, 5 min after medication administration. Number of participants with a significant drop in blood pressure (mmHg) compared to baseline would be counted for hypotension.

    Measured: 10 minutes

Questions about this trial

What is this clinical trial studying?

A study testing Dexmedetomidine and Adenosine in people with Supraventricular Tachycardia, run by University of Pittsburgh 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 1 inclusion and 4 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 28 Mar 2017. 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?

Yes. Results are posted in the registry (first posted 28 Mar 2017). 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?

Termination of SVT (time frame: Within 3 minutes). 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 NCT01495481, which also lists 2 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 28 Mar 2017.
