PEITHO Pulmonary Embolism Thrombolysis Study (PEITHO)

November 6, 2020 updated by: Assistance Publique - Hôpitaux de Paris

Comparison Trial Evaluating Efficacy and Safety of Single i.v. Bolus Tenecteplase Plus Standard Anticoagulation as Compared With Standard Anticoagulation in Normotensive Patients

Heparin is the reference therapy for most patients with pulmonary embolism. Some patients with sub-massive pulmonary embolism defined by normal blood pressure and dysfunction of the right ventricle have a higher mortality risk. It has been suggested that thrombolytic treatment, a drug that dissolves blood clots more rapidly, may reduce the mortality in those patients. The studies reported to date were unable to confirm or refute this hypothesis because the number of patients included in those studies is too low. The aim of the study is to compare thrombolytic treatment with heparin (which is the reference therapy for pulmonary embolism) in a large group of patients with sub-massive pulmonary embolism.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

A prospective, randomized, double-blind, placebo-controlled, international, multicentre, parallel-group comparison trial evaluating the efficacy and safety of single i.v. bolus tenecteplase plus standard anticoagulation as compared with standard anticoagulation in normotensive patients with acute pulmonary embolism and with echocardiographic and laboratory evidence of right ventricular dysfunction.Patients suffering from acute pulmonary embolism (first symptoms occurring within 15 days) confirmed by lung scanning or a positive spiral computed tomogram, or a positive pulmonary angiogram, presenting with right ventricular dysfunction on echocardiography and tested troponin I or T positive will be included in the study if they have no exclusion criteria.Patients in the investigational group will receive: Ø Tenecteplase as a single body-weight (known or estimated) adjusted IV bolus administered over 5 - 10 seconds not later than 30 minutes after randomization, and not later than 2 hours after the diagnosis of RV dysfunction Weight (kg) Dose in mg Dose in units Dose in ml<60 30 mg 6000 U 6 ml>60 to <70 35 mg 7000 U 7 ml>70 to <80 40 mg 8000 U 8 ml>80 to <90 45 mg 9000 U 9 ml>90 50 mg 10000 U 10 mlØ and: concomitant therapy-Unfractionated heparin at a dose of 80 IUxKg-1 as an intravenous bolus, followed by an infusion of 18 IUxKg-1xh-1, to be administered immediately after randomization in all patients for at least 48 hours following randomization. Beyond this period, intravenous UFH may be substituted with subcutaneous heparin (LMWH) treatment. The bolus will be omitted when heparin was started before randomisation.Patients in the control group will receive Ø placebo as a single body-weight (known or estimated) adjusted IV bolus administered over 5 - 10 seconds not later than 30 minutes after randomization, and not later than 2 hours after the diagnosis of RV dysfunction.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Description

Inclusion Criteria:

  • Age 18 years or older
  • Acute PE (first symptoms occurring 15 days or less before randomisation) confirmed by lung scan, or a positive spiral computed tomogram, or a positive pulmonary angiogram

  • Haemodynamic collapse at presentation as defined above
