Current Primary Outcome Measures (submitted: July 7, 2021)

Distribution of ordinal modified Rankin Scale (mRS) scores at 90 ± 14 days follow-up [ Time Frame: 90 ± 14 days follow-up ]

The difference in the distribution of ordinal modified Rankin Scale (mRS) scores at 90 ± 14 days follow-up in the ITT population to determine the performance of the DTAS triage imaging workflow involving Stroke CBCT reconstructions by the investigational device in comparison to the conventional CT/MR triage imaging workflow. The 90 day mRS score will be evaluated by a blinded assessor of a pool of blinded assessors (i.e., a specialist with mRS certification) at the local hospital by performing a structured interview of the patient in person using the Rankin Focused Assessment (RFA) structured mRS questionnaire. If subject is unable to return to the clinic for the day 90 ± 14 visit, a (video) call in which the mRS score is assessed by a blinded assessor is preferable to no assessment.

Descriptive Information

• Brief Title: WE-TRUST (Workflow Optimization to Reduce Time to Endovascular Reperfusion for Ultra-fast Stroke Treatment)
• Official Title: WE-TRUST (Workflow Optimization to Reduce Time to Endovascular Reperfusion for Ultra-fast Stroke Treatment)
• Brief Summary: The WE-TRUST study is a multi-center randomized clinical trial to assess the impact of a Direct to Angio Suite (DTAS) workflow on stroke patient outcomes.

Detailed Description

Outcomes for stroke patients are closely tied to how fast they receive treatment. Currently, when a possible stroke patient arrives at the emergency department, typically first a CT or MRI exam is acquired for stroke triage. In case of an ischemic stroke the patient is then treated in an interventional suite.

In the DTAS workflow stroke patients are diagnosed and treated in the interventional suite without interruption. The Cone-Beam CT (CBCT) capabilities of the interventional X-ray system are utilized to perform triage, directly followed by stroke treatment.

The primary objective of the WE-TRUST study is to demonstrate that the DTAS triage workflow involving CBCT results in superior patient outcome in ischemic stroke patients with confirmed Large Vessel Occlusion as compared to the conventional CT/MR triage workflow.

The WE-TRUST study will be running in 16 sites to enroll 500+ patients globally.
