Trial summary

Acute ischemic stroke (AIS) has been one of the major causes of global mortality and morbidity. The superiority of endovascular therapy (EVT) over standard medical therapy in treating AIS due to large vessel occlusion (LVO) in the anterior circulation has been widely accepted.

About this study

Official title: A Prospective, Multicenter, Randomized Clinical Trial to Evaluate the Safety and Efficacy of Intravascular Hypothermia Therapy of Patients With Acute Ischemic Stroke

Acute ischemic stroke (AIS) has been one of the major causes of global mortality and morbidity. The superiority of endovascular therapy (EVT) over standard medical therapy in treating AIS due to large vessel occlusion (LVO) in the anterior circulation has been widely accepted. However, a critical concern is that even with an extremely high rate of successful recanalization (the modified thrombolysis in cerebral infarction [mTICI] score 2b-3) around 90%, nearly half of the patients failed to benefit from EVT. So, adjunctive therapy of EVT for neuroprotection is required.

From the previous domestic and foreign literatures, hypothermia can prevent and treat secondary injury caused by ischemia-reperfusion injury and cerebral edema of acute cerebral ischemia, so as to achieve the role of neuroprotection. In this study, intravascular cooling was performed as soon as possible with careful temperature control in patients receiving thrombectomy. The temperature was controlled at 33° C for 48-72 hours. This parallel controlled study is to systematically evaluate the feasibility and safety of adjunctive therapy using early intravascular hypothermia in AIS patients receiving mechanical thrombectomy. The results will clarify a potential modality for neuroprotection and hopefully provide new evidence in improving patient prognosis.

Read the detailed description

In this study, the target subjects were AIS patients with successful recanalization (mTICI 2b-3). Early intravascular hypothermia neuroprotection therapy was given to patients after thrombectomy to evaluate its safety and effectiveness. The neuroprotection effect of endovascular hypothermia therapy is explored regarding several aspects, such as hemorrhagic conversion rate, cerebral edema, and neurological function recovery, with specific evaluation criteria described in detail in the following experimental design.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Intracranial hemorrhage conversion rate

    ICH

    Measured: 7 days after thrombectomy operation or discharge

Secondary outcomes (7)
  1. Modified Rankin scale (mRS)

    The mRS is a 7-point scale ranging from 0 (no symptoms) to 6 (death)

    Measured: 90 days

  2. The rate of functional independency (mRS 0-2)

    The mRS is a 7-point scale ranging from 0 (no symptoms) to 6 (death)

    Measured: 90 days

  3. The rate of mortality (mRS 6)

    The mRS is a 7-point scale ranging from 0 (no symptoms) to 6 (death)

    Measured: 90 days

  4. NIHSS

    Scores on the National Institutes of Health Stroke Scale (NIHSS) range from 0 to 42, with higher scores indicating more severe neurologic deficits.

    Measured: 24 hours, 7 days or discharge

  5. Rate of symptomatic intracranial hemorrhage (sICH)

    The diagnosis of sICH was based on the association of ICH with any of the following. conditions: (1) Increase in NIHSS score > 4 points compared to the score before ICH; (2) Increase in NIHSS score by >2 points in one category; (3) deterioration leading to intubation, hemicraniectomy, external ventricular drain placement, or any other major interventions.

    Measured: 7 days after thrombectomy operation or discharge

  6. Rate of malignant cerebral edema

    Development of signs of herniation (including decrease in consciousness and/or anisocoria), accompanied by midline shift >= 5 mm on follow-up imaging.

    Measured: 7 days after thrombectomy operation or discharge

  7. Infarct volume

    measured on 5-7 days CT (or MRI if available)

    Measured: 5-7 days after thrombectomy operation or discharge

Who may be eligible to take part?

The sponsor lists 9 inclusion and 26 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: status not confirmed, as of the sponsor's last update on 6 Jun 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. 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. Some participants in this study may receive a placebo. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Liqun Jiao,MD, PhD (13911224991, liqunjiao@sina.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Intracranial hemorrhage conversion rate (time frame: 7 days after thrombectomy operation or discharge). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 6 Jun 2022.
