New study pits Clot-Removal devices against drugs for dangerous lung clots

NCT ID NCT06453876

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This phase 3 trial will test three ways to treat intermediate high-risk pulmonary embolism (a serious blood clot in the lungs). The study compares two catheter-based procedures (mechanical clot removal or low-dose clot-busting drug) with standard blood-thinning heparin. About 210 adults with recent symptoms will be enrolled. The goal is to see which method reduces clot burden most effectively within 48-96 hours.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Heparin, Alteplase, and catheter-based devices (AlphaVAC, FlowTriever, EKOS)

What this could lead to

If successful, this trial could identify the best approach to quickly reduce blood clots in the lungs, potentially improving recovery and reducing complications for people with serious pulmonary embolism.

What could go wrong

This is a phase 3 trial, but results may not apply to all patients. Bleeding risks exist with all treatments, and the study is relatively small (210 participants).
