Who this trial is looking for
This trial is looking for people who have recently had a stroke caused by narrowing of blood vessels in the brain. Participants will undergo an MRI to help researchers learn more about treatment options for this condition.
Are You a Good Fit for This Trial?
You may be able to join if
I had a stroke within the last 30 days
I have narrowing of my brain's blood vessels by 70-99%
I am enrolled in the CAPTIVA trial
I can have an MRI within 14 days of enrolling
You may not be able to join if
I cannot have an MRI
I am allergic to gadolinium contrast
I have kidney disease with a low eGFR

CAPTIVA-MRI is an observational multimodal MR imaging study that is ancillary to the CAPTIVA trial \[a 3-arm, double-blind Phase III trial conducted at approximately 115 StrokeNet sites randomizing patients with stroke attributed to 70-99% intracranial atherosclerotic stenosis (ICAS) to aspirin plus ticagrelor, clopidogrel, or rivaroxaban.\] The primary goal of this ancillary study is to determine…
CAPTIVA-MRI is an observational multimodal MR imaging study that is ancillary to the CAPTIVA trial \[a 3-arm, double-blind Phase III trial conducted at approximately 115 StrokeNet sites randomizing patients with stroke attributed to 70-99% intracranial atherosclerotic stenosis (ICAS) to aspirin plus ticagrelor, clopidogrel, or rivaroxaban.\] The primary goal of this ancillary study is to determine if MRI biomarkers can potentially identify ICAS patients who fail best medical management. The CAPTIVA-MRI study leverages the CAPTIVA trial design and implementation to capture information that will inform and facilitate the next generation of ICAS trials and the management of patients with ICAS.
