What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether giving a clot-busting drug called tenecteplase directly into the brain artery after mechanical clot removal helps people recover better from a severe stroke. About 462 adults with a large vessel blockage in the front part of the brain will be randomly assigned to receive either the drug or a placebo within 24 hours of symptoms. The goal is to see if the drug reduces disability and improves independence.

Inclusion Criteria: * Adult participants (age≥18 years) presenting with ischemic stroke with arterial LVO on CT/MR Angiogram of the intracranial internal carotid or middle cerebral artery (MCA) first segment (M1) or proximal second segment (M2) committed to thrombectomy using standard criteria within 24 hours of onset: * For 0-6 hours of symptom onset: Presence of arterial occlusion as defined above and ASPECTS≥3 on NCCT * For 6-24 hours of symptom onset: Additional imaging criteria on CTP or MRI perfusion of core volume \<100ml. * Qualifying CT/MR within 4hrs of randomisation (repeat CT for transferred participants required if \>4hr) * Pre-stroke Modified Rankin Scale (mRS) score of ≤2 (mild pre-existing disability permitted) * Local legal requirements for consent have been satisfied. Exclusion Criteria: * Intracranial hemorrhage identified by CT or MRI * ASPECTS 0-2 on NCCT * CTP or MRI perfusion ischemic core volume \>100ml if presenting within 6-24 hours from symptoms onset * Anticipated endovascular stenting required for intracranial or extracranial atherosclerotic stenosis/occlusion. * More than six retrieval attempts in the same vessel * Alteplase being infused within 30 minutes (\~5x half-life) of anticipated trial drug administration * Contraindication to imaging with contrast agents * Any condition (eg.mid-arterial phase early venous filling) that in the judgment of investigators could impose hazards if study therapy is initiated * Pregnant women. * Current participation in another intervention research study that includes experimental interventions beyond standard-of-care. * Anticoagulation. INR ≤1.7 if on warfarin, and dabigatran reversal by idarucizumab are permitted. * Other standard contraindications to thrombolysis apart from time window. * Known terminal illness such that the participants would not be expected to survive a year. * Planned withdrawal of care or comfort care measures.
