Pulmonary embolism treatment with catheter-directed thrombus removal versus no catheter therapy

Official title: 1/2 Pulmonary Embolism: Thrombus Removal with Catheter-Directed Therapy (PE-TRACT Trial)

Funded at New York University School of Medicine · NIH-11381072 · Data updated 2026-11-12

This study tests whether removing clot with a targeted catheter approach helps people with submassive pulmonary embolism feel better and move more easily, compared with not using catheter therapy.

Who could benefit from this research

Could help

Adults with submassive pulmonary embolism and right heart dysfunction who are candidates for catheter-directed therapy at participating centers.

Less likely to help

Patients whose condition progresses rapidly or who do not meet catheter-directed therapy criteria may not benefit.

What this research studies

If you have submassive pulmonary embolism with right heart strain, this trial will compare catheter-directed therapy to not using catheter therapy. It uses adaptive enrollment and blinded assessment to measure short-term fitness (peak oxygen use at 3 months) and long-term heart–lung function (NYHA class at 12 months). The study aims to see if a targeted, lower-dose clot-busting treatment can provide similar benefits to systemic therapy but with less bleeding, potentially improving quality of life over time. Participants will be randomly assigned to CDT or no-CDT and will be monitored for safety and outcomes through follow-ups coordinated by NYU School of Medicine. An interim analysis could stop the trial early if results are clearly superior or futile.

Why it matters

Potential benefit: If successful, CDT could reduce symptoms, improve functional capacity, and enhance long-term quality of life for people with submassive PE while minimizing bleeding risks.

How similar studies have gone: Prior evidence suggests catheter-directed therapy may offer similar efficacy to systemic thrombolysis with potentially lower bleeding, but results are evolving and this large trial will provide more definitive answers.
