About this study
Official title: Predictors of Good Outcomes in Thrombectomy for Stroke Patients Within 24 Hours From Symptom Onset With Large Infarct Core
Identify the factors associated with a favorable clinical outcome in participants with acute ischemic stroke and large core infarcts within 24 hours of onset who are treated with endovascular intervention.
Read the detailed description
In 2022 and early 2023, three randomized controlled trials-RESCUE-JAPAN LIMIT, SELECT 2, and ANGEL ASPECT-were published in the New England Journal of Medicine. These trials demonstrated the effectiveness and safety of endovascular intervention using clot retrieval devices in participants with acute ischemic stroke and large core infarcts. However, the rate of participants achieving a good recovery remains low, while the mortality and disability rates are very high.
Moreover, in Vietnam, the acute stroke treatment process has not been optimized, and the facilities and equipment for monitoring neurointensive care are not fully equipped. As a result, endovascular intervention using clot retrieval devices in participants with large core infarcts has not been widely implemented in the investigator's country, and the effectiveness and safety of this treatment method have not been clearly evaluated.
Addressing this issue is crucial for improving the quality of life and reducing the mortality and disability rates caused by stroke in this participant group. This study aims to provide new insights into the use of endovascular intervention for treating acute ischemic stroke with a large core infarct volume, thereby supporting clinical decision-making and improving treatment outcomes for participants with acute ischemic stroke and large core infarcts.
We hypothesize that core infarction is not the sole factor for excluding patients from potent thrombectomy therapy. We aim to determine predictors of favorable and unfavorable outcomes following thrombectomy in patients with large core strokes. Secondly, we aim to build a multivariable calculator to predict good or poor outcomes after thrombectomy.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Endovascular treatmentProcedure or surgery
Also called Mechanical thrombectomy
This procedure is instrumental in restoring cerebral blood flow by addressing the clot-induced obstruction within brain-supplying blood vessels.
| Study group | Role | What they receive |
|---|---|---|
| Good outcome | mRS of 0-3; mRS of 0-2 Receives: Procedure: Endovascular treatment | |
| Unfavorable outcomes | mRS of 4-6 Receives: Procedure: Endovascular treatment |
What is being measured
The primary outcome is the main question the study is designed to answer.
The Modified Rankin Scale (mRS) of 0-3
The rate of independent ambulation (mRS 0-3). The scale runs from 0-6, running from perfect health without symptoms to death.
Measured: 90 (± 14 days) after procedure
Secondary outcomes (4)
mRS of 0-2
The rate of functional independence (mRS 0-2)
Measured: 90 (± 14 days) after procedure
mRS of 0-5
The survival rate
Measured: 90 (± 14 days) after procedure
Symptomatic intracerebral hemorrhage (sICH)
sICH means any hemorrhage with neurological deterioration, as indicated by an NIHSS score that was higher by ≥4 points than the value at baseline or the lowest value in the first 72 hours or any hemorrhage leading to death.
Measured: 72 hours
Early neurological deterioration
Clinical worsening that was higher by ≥4 points than the value at baseline during the first 72 h after ischaemic stroke.
Measured: 72 hours

Questions about this trial
What is this clinical trial studying?
An observational study of Acute Ischemic Stroke, run by 115 People's Hospital at 4 sites in Vietnam.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 2 Sep 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 4 sites in Vietnam. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
The Modified Rankin Scale (mRS) of 0-3 (time frame: 90 (± 14 days) after procedure). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06016348, which also lists 5 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 2 Sep 2025.
