Our robust patient care is complemented by our depth of experience in clinical trials. Some of our latest clinical trials in stroke includes, CSF delivery of a drug to prevent ischemic stroke after subarachnoid hemorrhage. DEFUSE 3 is an NIH-funded trial testing the safety and efficacy of mechanical thrombectomy plus medical management compared to medical management alone treated between six to 16 hours after a large artery ischemic stroke. Perfusion CT and/or advanced MR imaging will be used to identify candidates for this trial. Keck Medicine of USC is the only trial site in Los Angeles. ENRICH is an industry-sponsored randomized controlled trial utilizing early, minimally invasive removal of intracerebral hemorrhage.
