Pulmonary Embolism - Thrombus Removal With Catheter-Directed Therapy

Purpose

PE-TRACT is an open-label, assessor-blinded, randomized trial, aiming to compare catheter-directed therapy (CDT) and anticoagulation (CDT group) with anticoagulation alone (No-CDT) in 500 patients with submassive PE, proximal pulmonary artery thrombus and right ventricular dilation.

Condition

  • Pulmonary Embolism

Eligibility

Eligible Ages
Over 18 Years
Eligible Genders
All
Accepts Healthy Volunteers
No

Inclusion Criteria

  1. Symptomatic PE diagnosed by contrast-enhanced CT angiography with involvement of a main or lobar pulmonary artery branch; and 2. Right ventricular (RV) dilation as defined by the presence of an RV/Left ventricular ratio > 1 on CT angiography

Exclusion Criteria

  1. Age < 18 years 2. Systolic blood pressure < 90 mmHg for >15 consecutive minutes or > 40 mmHg drop from baseline, or vasopressor requirement for blood pressure support (i.e., massive PE), occurring within 1 hour prior to eligibility assessment. 3. Symptom duration > 14 days for the current PE episode 4. Irreversible INR > 3 5. Irreversible Thrombocytopenia (Platelets < 50,000/microliter) 6. Creatinine > 2.0 mg/dl 7. Hemoglobin < 7.0 g/dl 8. Pregnancy (positive urine or blood pregnancy test (a pregnancy test must be obtained within 7 days prior to randomization in people of childbearing potential)) 9. Allergy or hypersensitivity to Recombinant Tissue Plasminogen Activator (rt-PA), or iodinated contrast, except for mild-moderate contrast allergies for which steroid pre-medication can be used 10. Life expectancy < 1 year 11. Chronic inability to independently walk prior to the current PE episode (e.g. wheelchair dependent, walker or cane dependent, paraplegic, and/or bed-bound) 12. Allergy to heparin or history of Heparin-Induced Thrombocytopenia (HIT) 13. Unable or unwilling to provide informed consent 14. Major contraindication or unsuitability for all CDT methods available at the Clinical Center

Arm Groups

ArmDescriptionAssigned Intervention
Experimental
Catheter-Directed Therapy (CDT) plus Anticoagulation 		Participants will receive CDT consisting of mechanical thrombectomy (MT) or intrathrombus catheter-directed thrombolysis (CDL) using FDA-cleared devices for pulmonary embolism (PE). The exact technique and devices used will be at the discretion of the endovascular physician, within parameters defined by the PE-TRACT Manual of Operations (MOP) and accepted standard care. Before and after CDT, patients will receive standard PE therapy as in the no-CDT Arm.
  • Drug: Anticoagulant Therapy
    All subjects will receive anticoagulation for a minimum of 3 months.
  • Device: Catheter-Directed Therapy
    The endovascular physician can choose to use either mechanical thrombectomy (MT) using a device cleared by the FDA to treat PE or catheter-directed thrombolysis (CDL) using an infusion catheter cleared by the FDA to administer thrombolytic drugs for the treatment of PE
Active Comparator
No Catheter-Directed Therapy (No-CDT) 		Standard anticoagulant therapy (FDA-approved regimen) for the treatment of PE.
  • Drug: Anticoagulant Therapy
    All subjects will receive anticoagulation for a minimum of 3 months.
