Could donor blood particles protect hearts after stenting?

NCT ID NCT04327635

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

Summary

This early study tested whether a biologic called PEP, made from donor blood particles, is safe to infuse into heart arteries right after stent placement. Nine patients received a single dose during catheterization. The goal was to see if PEP could reduce heart damage, but the main focus was on safety and finding the right dose.

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

Active substance

PEP (extracellular vesicles from donor blood)

What this could lead to

If safe, this could lead to a new way to limit heart muscle damage after stent placement.

What could go wrong

This is a very early Phase 1 trial with only 9 participants, so safety and effectiveness are not yet proven. There are risks of allergic reactions, infection, or heart rhythm problems.
