Second chance: could a repeat Clot-Buster save stroke patients?
NCT ID NCT07375953
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether giving a second dose of the clot-busting drug tenecteplase can help stroke patients who don't get better within an hour of the first dose. About 120 adults with acute ischemic stroke will receive either a second dose or standard care. The goal is to see if the extra dose is safe and improves recovery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Tenecteplase (a clot-busting drug)
- What this could lead to
- If it works, this could offer a rescue treatment for stroke patients who don't respond to the first clot-busting drug, potentially reducing disability.
- What could go wrong
- This is a small, early-phase trial (120 people) testing safety and feasibility. The second dose may increase bleeding risk, and results may not apply to all stroke patients.
