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.
