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

Summary

This study tests a procedure that uses ultrasound and a catheter to deliver a low dose of a clot-dissolving drug directly to blood clots in the lungs. The goal is to quickly reduce the strain on the heart and improve blood flow, while keeping the risk of serious bleeding low. The trial includes 60 adults with severe but stable pulmonary embolism and signs of heart stress.

What this could mean

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

Active substance

Tissue plasminogen activator (tPA) - a clot-dissolving drug

What this could lead to

If successful, this could offer a safer, lower-dose way to treat dangerous blood clots in the lungs, reducing heart strain and bleeding complications.

What could go wrong

This is an early, single-arm study with only 60 participants, so results may not apply broadly. The trial is currently suspended, and bleeding risks remain a concern.
