About this study

Official title: A Phase 3, Randomized, Placebo-Controlled, Double-Blind Study of the Aureva Transcranial Ultrasound Device With Tissue Plasminogen Activator in Patients With Acute Ischemic Stroke (TRUST)

This is a randomized, placebo controlled, double-blind phase 3 clinical study to evaluate the efficacy and safety of transcranial ultrasound (TUS) using the Sonolysis Headframe as an adjunctive therapy to intravenous (IV) tissue plasminogen activator (tPA) therapy in subjects with acute ischemic stroke that initially present at non-endovascular (EVT) treating hospitals that have established transport services in place to transfer subjects to hospitals capable of performing EVT.

Read the detailed description

The primary objective of this study is to assess the safety and efficacy of TUS using the Sonolysis Headframe in combination with systemic tPA (Treatment group) compared to systemic tPA alone (Control group) in subjects with acute ischemic stroke.

Number of Subjects Required:

Lead-in Phase: 40 subjects in the U.S.; Primary Phase: 556 total enrolled subjects (278 per arm)

Number of Study Centers:

Lead-in Phase: Up to 20 Institutions in U.S.; Primary Phase: Up to 70 Institutions worldwide

Being tested
tPA in combination with the Sonolysis Headframe (TUS), tPA in combination with the Sonolysis Headframe (Sham TUS)

What is being measured

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

  1. Complete recanalization measured by modified Arterial Occlusive Lesion (mAOL)

    Complete recanalization of the primary occluded vessel as measured by the modified Arterial Occlusive Lesion (mAOL) scoring system. The mAOL assigns a score from 0 to 3, which represents the range from no recanalization to complete recanalization based on either the presence (grade 2 or 3) or absence (grades 0 or 1) of any downstream flow.

    Measured: 90-120 minutes post TUS treatment before EVT

Secondary outcomes (4)

  1. modified Rankin Scale (mRS) score 0-2

    Functional dependence at 90 days as measured by the modified Rankin Scale (mRS). The mRS consists of 7 grades, (0-6), with 0 corresponding to no symptoms and 6 corresponding to death. For this study, functional independence will be defined as those subjects that achieve a mRS score of 0-2 at 90 days.

    Measured: 90 days +/- 10 days

  2. Neurologic Status at 24 hours post treatment measured by National Institute of Health's Stroke Scale (NIHSS).

    NIHSS has 15 items. Ratings for each item are scored on a 0-3 to 0-5 scale, with a total score of 0 for normal and 42 for maximally impaired.

    Measured: 24 hours post TUS treatment

  3. Partial or complete recanalization as measured by mAOL score of 2-3.

    See description in Primary Outcome Measure.

    Measured: 90-120 minutes post TUS treatment before EVT

  4. Partial or complete recanalization as measured by Thrombolysis In Cerebral Ischemia (TICI) score of 2-3

    TICI Scale: [0] - No antegrade flow beyond the point of occlusion. [1] - The contrast material passes beyond the area of obstruction but fails to opacify the entire cerebral bed distal to the obstruction. [2] - The contrast material passes beyond the obstruction and opacifies the arterial bed distal to the obstruction. However, the rate of entry of contrast into the vessel distal to the obstruction and/or its rate of clearance from the distal bed are perceptibly slower than its entry into and/or clearance from comparable areas not perfused by the previously occluded vessel. [3] - Antegrade flow into the bed distal to the obstruction occurs as promptly as into the obstruction and clearance of contrast material from the involved bed is as rapid as from an uninvolved other bed of the same vessel or the opposite cerebral artery.

    Measured: 90-120 minutes post TUS treatment before EVT

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 10 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 30 Nov 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 2 sites in United States. 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?

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?

Complete recanalization measured by modified Arterial Occlusive Lesion (mAOL) (time frame: 90-120 minutes post TUS treatment before EVT). 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 NCT03519737, which also lists 25 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 30 Nov 2018; AzTrials last refreshed its copy on 8 Nov 2026.
