Trial summary

This clinical trial aims to learn whether blood pressure (BP) guided by individualized cerebral autoregulation (CA) is safe and provides a better prognosis than a fixed target in patients with ischemic stroke after endovascular therapy. The BP of participants will be managed at least 48 hours after revascularization. Read more about this study

About this study

Official title: Cerebral Hemodynamic Management Based on Cerebral Autoregulation Monitoring in Acute Ischemic Stroke Patients After Endovascular Treatment: a Multicenter, Open-label, Randomized Control Study

This clinical trial aims to learn whether blood pressure (BP) guided by individualized cerebral autoregulation (CA) is safe and provides a better prognosis than a fixed target in patients with ischemic stroke after endovascular therapy. The BP of participants will be managed at least 48 hours after revascularization. Researchers will compare the CA-guided BP group with the fixed target BP group to mainly see if individualized BP could help more patients to have their neurological function improved at seven days.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Hypotensive Drugs and/or Vasoactive DrugsDrug

    To manipulate the blood pressure within a certain range with hypotensive drugs (e.g. nifedipine, benidipine, captopril, benazepril, irbesartan, labetalol, urapidil) and/or vasoactive drugs (noradrenaline or dopamine).

Study groups in NCT05670028
Study groupRoleWhat they receive
CA-guided BPExperimentalThe upper and lower limits of autoregulation determined by ICM+ software are used to guide the range of blood pressure control, but no more than 40% above or below the usual BP. From when the upper or lower limit of autoregulation appeared in ICM+ software to 48h after revascularization, the total time of actual BP beyond the CA range will be no more than two hours through drug intervention.
Receives: Drug: Hypotensive Drugs and/or Vasoactive Drugs
Fixed target BPActive comparatorAfter randomization to 48h after endovascular therapy, the target of BP was determined by clinicians according to current guidelines, i.e. <180/105mmHg.
Receives: Drug: Hypotensive Drugs and/or Vasoactive Drugs

What is being measured

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

  1. Early neurological recovery

    the NIHSS score decreased by ≥ 4 from the preoperative baseline

    Measured: Seven days after endovascular therapy (or on the discharge if less than seven days)

Secondary outcomes (3)
  1. The proportion of functional independence with modified Rankin Scale scores 0-2

    The Modified Rankin Scale (mRS) is a disability scale with possible scores ranging from 0 (no residual symptoms) to 6 (dead).

    Measured: 90 days after endovascular therapy

  2. Distribution of modified Rankin Scale scores ranging from 0-6

    To compare the difference in the distribution of mRS scores. The Modified Rankin Scale (mRS) is a disability scale with possible scores ranging from 0 (no residual symptoms) to 6 (dead).

    Measured: 90 days after endovascular therapy

  3. Infarct volume growth

    The infarct volume at the preoperative baseline is defined as the area with rCBF<30% or ADC<620mm×10^-6mm^2/s via RAPID software and that at seven days is measured manually on brain CT.

    Measured: Seven days after endovascular therapy (or on the discharge if less than seven days)

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Hypotensive Drugs and/or Vasoactive Drugs in people with Ischemic Stroke and Revascularization, run by Beijing Tiantan Hospital.

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 4 inclusion and 10 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 5 Jan 2023. Status can change between updates, so confirm with the study contact before making plans.

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.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

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?

Early neurological recovery (time frame: Seven days after endovascular therapy (or on the discharge if less than seven days)). 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 NCT05670028, which also lists 14 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 5 Jan 2023.
