Stroke drug combo aims to boost recovery
NCT ID NCT06949228
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether giving the clot-busting drug tenecteplase directly into the brain artery after mechanical clot removal can improve outcomes for people with acute ischemic stroke. About 132 adults aged 18-85 with large vessel blockages will be randomly assigned to receive the drug or standard care. The goal is to see if the drug helps more patients recover with little or no disability at 90 days, while monitoring for brain bleeding.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- tenecteplase
- What this could lead to
- If it works, this could improve recovery and reduce disability after a severe stroke by clearing remaining clots.
- What could go wrong
- This is an early combined Phase 2/3 trial with only 132 participants, so results may not apply to all stroke patients. There is a risk of brain bleeding from the drug.
