About this study

Official title: A Randomised, Open-label, Multi-center, Angiographic Trial to Compare the Efficacy and Safety of Single Bolus of Tenecteplase (Metalyse®) With Accelerated Infusion of Alteplase in Asian Patients With Acute Myocardial Infarction

The objective of this trial was to compare the efficacy and safety of a single bolus of TNK-tPA (tenecteplase, Metalyse®) compared with rt-PA (alteplase, Actilyse®) in Asian patients.

Read the detailed description

This was a randomized (1:1), open-label, multi-center, active-control, parallel-group study to compare the efficacy and safety of TNK-tPA (tenecteplase, Metalyse®) with that of accelerated rt-PA (alteplase, Actilyse®) in Asian patients with AMI. The primary endpoint (TIMI 3 Flow) and the secondary endpoint (TIMI frame count) were evaluated in a blinded manner in the core laboratory.

Patients eligible for the trial who met all inclusion and exclusion criteria and who gave their informed consent were randomized to one of two treatment groups (i.e. TNK-tPA or accelerated rt-PA).

The study period totaled 30-37 days and included baseline, randomisation, study drug administration, in-hospital follow-up and thirty-day follow-up.

Coronary angiography was performed at 90 minutes after the start of study drug administration. 12-lead electrocardiograms (ECGs) were obtained before randomization, between 60 to 75 minutes and 180 ± 15 minutes after the start of study drug administration, and at hospital discharge.

If the patient showed rapid and progressive hemodynamic deterioration before 90 minutes, rescue PTCA or other appropriate interventions should be performed at the discretion of the treating physician.

Following the analysis of TIMI flow and frame count at each study center, the results were carefully recorded on the CRFs. This data was stored on a compact disk or a film and labeled with the subject's study I.D. number. It was then sent with the summary worksheets and ECGs to the Angiographic Core Laboratory located at the Leuven Coordinating Center (LCC) of the University Hospital Gasthuisberg (Leuven, Belgium) for central evaluations.

Study Hypothesis:

The null hypothesis tested was that there was no difference between the two treatment groups: TNK-tPA (Tenecteplase, Metalyse®) and accelerated rt-PA (Actilyse®), against the alternative that there was a difference.

Comparison(s):

The primary endpoint of the study was TIMI 3 flow at 90 minutes after start of thrombolytic therapy, angiograms were evaluated in a blinded manner in a core laboratory.

What participants receive

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

  • TNK-tPADrug

  • rt-PADrug

What is being measured

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

  1. The percentage of patients with thrombolysis in myocardial infarction (TIMI) grade 3 flow in the infarct-related artery (IRA)

    Measured: at 90 minutes after the start of thrombolytic treatment

Secondary outcomes (5)
  1. Infarct-related artery patency

    Measured: at 90 minutes

  2. The percentage of subjects with ST-segment resolution

    Measured: at 60 and 180 minutes

  3. Mortality

    Measured: 30-days

  4. Safety

  5. The effects of TNK-tPA on coagulation and fibrinogenolysis (at selected clinical sites)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing TNK-tPA and rt-PA in people with Myocardial Infarction, run by Boehringer Ingelheim at 18 sites in 3 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 8 inclusion and 15 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 29 Oct 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 18 sites in China, South Korea, Hong Kong. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

The percentage of patients with thrombolysis in myocardial infarction (TIMI) grade 3 flow in the infarct-related artery (IRA) (time frame: at 90 minutes after the start of thrombolytic treatment). 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 29 Oct 2013.
