RapidAI Has Been Used in the Most Influential Stroke Clinical Trials Around the World

Our clinical trials are producing high-quality data for healthcare decision making, and are helping us continue to redefine stroke care. They help us evaluate stroke interventions and disease treatment safety and efficacy.

Growing Healthcare Impact: 14 Clinical Trials Worldwide

See details of those trials below, from objective to status, design, endpoint, and more.

CRISP

OBJECTIVE

Determine if Rapid CTP can help physicians accurately predict response to recanalization in AIS patients undergoing endovascular therapy.

STATUS

Patients with a Target mismatch profile on Rapid who were treated up to 18 hours after stroke onset had a favorable clinical response rate of 83% following reperfusion.

SELECTION
Rapid imaging for 100% of patients
DESIGN
Prospective, observational
TX WINDOW
0–18 hours
ENDPOINT
30-day NIHSS

DAWN

OBJECTIVE

Evaluate if Trevo thrombectomy plus medical management leads to superior clinical outcomes at 90 days as compared to medical management alone in selected AIS patients.

STATUS

Early termination for efficacy. Highest rate of clinical benefit (36% absolute risk reduction) in any endovascular stroke trial.

SELECTION
Rapid imaging for 100% of patients
DESIGN
PROBE, adaptive design
TX WINDOW
6–24 hours
ENDPOINT
90-day average weighted mRS

DEFUSE 2

OBJECTIVE

Determine if perfusion imaging can help identify which patients, who are ineligible or failed IV tPA, are most likely to benefit from an endovascular clot removal procedure.

STATUS

Complete

SELECTION
Rapid imaging for 100% of patients
DESIGN
Prospective, observational
TX WINDOW
0–12 hours

Stopped for efficacy

SELECTION
Rapid imaging for 100% of patients
DESIGN
PROBE, adaptive design
TX WINDOW
6–16 hours

EXTEND

OBJECTIVE

Determine if AIS patients selected with significant penumbral mismatch (measured by MRI criteria) will have improved clinical outcomes when given intravenous tissue plasminogen activator (tPA) compared to placebo.

STATUS

Stopped for efficacy

SELECTION
Rapid imaging for 100% of patients
DESIGN
Prospective, randomized, double-blinded
TX WINDOW
3–9 hours
ENDPOINT
mRS 0-1 at 90 days

EXTEND-AI

OBJECTIVE

Determine whether more advanced imaging selection, newer generation devices, and earlier intervention improve outcomes.

STATUS

Early termination for efficacy. Highest rate of favorable clinical outcome (71%) in any endovascular stroke trial.

SELECTION
Rapid imaging for 100% of patients
DESIGN
PROBE, adaptive design
TX WINDOW
0–6 hours
ENDPOINT
Reperfusion at 24 hrs; NIHSS reduction ≥ 8 or Day 3 NIHSS 0 or 1

Assess the efficacy and safety of intravenous tenecteplase vs. tPA for bridging therapy prior to early window thrombectomy.

STATUS

Complete

SELECTION
Rapid imaging
DESIGN
Prospective, randomized, open-label, blinded endpoint (PROBE)
TX WINDOW

ENDPOINT
Proportion of patients with substantial angiographic reperfusion (as defined by mTICI score of 2b/3) at initial angiogram

FRAME

OBJECTIVE

Investigate the relationship between the success of mechanical thrombectomy performed within 6 hours after onset, the rate of good functional outcome at 3 months, and the presence or absence of Target mismatch on acute multimodal imaging.
