NCT04430569

Brief Summary

In this study, we will assess the efficacy and safety of a reduced dose of thrombolytic therapy given in addition to low-molecular-weight heparin in patients with intermediate-high-risk acute pulmonary embolism. Half of participants will receive thrombolytic treatment, while the other half will receive a placebo.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age 18 years or older
  • Objectively confirmed acute PE with first symptoms occurring 2 weeks or less before randomization. Objective confirmation is based on at least one of the following criteria: (a) at least one segmental ventilation-perfusion mismatch on lung scanning; (b) a spiral computed tomography pulmonary angiography or pulmonary angiography showing a filling defect or an abrupt obstruction of a segmental or more proximal pulmonary artery
  • Acute PE confirmed within 24 hours prior to randomization
  • Elevated risk of early death, or of hemodynamic collapse, or PE recurrence, indicated by at least one of the following criteria: (a) systolic blood pressure ≤ 110 mm Hg over at least 15 minutes upon enrolment, (b) temporary need for fluid resuscitation and/or treatment with low-dose catecholamines, provided that the patient could be stabilized within 2 hours of admission and maintains SBP of ≥ 90 mmHg and adequate organ perfusion without catecholamine infusion; (c) respiratory rate \> 20/min or oxygen saturation on pulse oximetry SpO2 \<90% o(or partial arterial oxygen pressure \< 60 mm Hg) at rest while breathing room air, (d) documented history of chronic symptomatic heart failure
  • Right ventricular dysfunction indicated by RV/LV diameter ratio \>1.0 on echocardiography apical four-chamber or subcostal four-chamber view or on Computed Tomography Pulmonary Angiography (transverse plane)
  • Serum troponin I or T concentration above the upper limit of local normal using a high-sensitivity assay
  • Ability to randomize the patient within 6 hours after the investigator receives the results of the second of the two criteria for RV dysfunction (RV/LV diameter ratio \>1.0) and myocardial injury (serum troponin I or T concentration above the upper limit of local normal), whichever comes latest.
  • Signed informed consent form

You may not qualify if:

  • Hemodynamic instability
  • Active bleeding
  • History of non-traumatic intracranial bleeding, any time
  • Acute ischemic stroke or transient ischemic attack (TIA) within the previous 6 months
  • Known central nervous system neoplasm/metastasis
  • Neurologic, ophthalmologic, abdominal, cardiac, thoracic, vascular or orthopedic surgery or trauma within 3 previous weeks
  • Platelet count \< 100 G/L
  • INR \> 1.4. If INR not available: prothrombin time ratio \< 60%. If both INR and prothrombin time ratio are measured, INR is relevant for the assessment of this criterion.
  • Treatment with antiplatelet agents other than (a) acetylsalicylic acid (ASA) ≤ 100 mg once daily or (b) clopidogrel 75 mg once daily or (c) a single loading dose of ASA or clopidogrel. Dual antiplatelet therapy (ASA + clopidogrel) is not allowed.
  • Known pericarditis or endocarditis
  • Known significant bleeding risk according to the investigator's judgement
  • Administration of thrombolytic agents within the previous 4 days
  • Vena cava filter insertion or pulmonary thrombectomy within the previous 4 days
  • Current participation in another interventional clinical study
  • Previous enrolment in this study
  • +10 more criteria

Access Criteria
Data sharing must be accepted by the sponsor and the PI based on scientific project and scientific involvement of the PI team. The founder could be involved in the decision. Teams wishing obtain IPD must meet the sponsor and IP team to present scientifics (and commercial) purpose, IPD needed, format of data transmission, and timeframe. Technical feasibility and financial support will be discussed before mandatory contractualization.
