Thrombolysis Using Tenecteplase (Metalyse®) in Cardiac Arrest - The TROICA Trial

2014-08-27 03:51:25 | BioPortfolio


The general aim of this study is to compare the efficacy and safety of tenecteplase to standard treatment during cardiopulmonary resuscitation in patients suffering from out-of-hospital cardiac arrest.


The trial is a prospective, international, multi-centre, randomised (1:1), double-blind, parallel group comparison conducted for investigating the efficacy and safety of tenecteplase and placebo in patients with cardiac arrest of presumed cardiac origin.

Approximately 1300 patients (two groups of 650 patients; tenecteplase or matching placebo) suffering from witnessed (by eye or ear) out-of-hospital cardiac arrest of presumed cardiac origin, who are treated with ALS-CPR will be randomised at approximately 40 study centres. Randomisation is done immediately after insertion of an IV line is established. Study drug application, as a single IV bolus over 5-10 seconds, should be done immediately after the first vasopressor application during the ALS-CPR procedure.

PCI facilities will be required at all participating sites, i.e. hospitals receiving patients.

Study Hypothesis:

The primary aim of the trial is to demonstrate superiority in the intent-to-treat analysis of tenecteplase over placebo with regard to primary endpoint as the incidence of 30-day survival (30daysurv).


Group A (experimental; fibrinolytic treatment) Tenecteplase, as a single IV bolus over 5-10 seconds, immediately after first vasopressor dosage during standardised ALS-CPR procedures according to the International CPR Guidelines.

Group B (reference) Placebo, as a single IV bolus over 5-10 seconds, immediately after first vasopressor dosage during standardised ALS-CPR procedures according to the International CPR Guidelines.

Medical and Biotech [MESH] Definitions

Cessation of heart beat or MYOCARDIAL CONTRACTION. If it is treated within a few minutes, heart arrest can be reversed in most cases to normal cardiac rhythm and effective circulation.

Occurrence of heart arrest in an individual when there is no immediate access to medical personnel or equipment.

The artificial substitution of heart and lung action as indicated for HEART ARREST resulting from electric shock, DROWNING, respiratory arrest, or other causes. The two major components of cardiopulmonary resuscitation are artificial ventilation (RESPIRATION, ARTIFICIAL) and closed-chest CARDIAC MASSAGE.

A procedure to stop the contraction of MYOCARDIUM during HEART SURGERY. It is usually achieved with the use of chemicals (CARDIOPLEGIC SOLUTIONS) or cold temperature (such as chilled perfusate).

The omission of atrial activation that is caused by transient cessation of impulse generation at the SINOATRIAL NODE. It is characterized by a prolonged pause without P wave in an ELECTROCARDIOGRAM. Sinus arrest has been associated with sleep apnea (REM SLEEP-RELATED SINUS ARREST).
