Comparison of Anti-coagulation and Anti-Platelet Therapies for Intracranial Vascular Atherostenosis- Magnetic Resonance Imaging

About this study

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.
