SEACOAST 1- SEdAtion With COllAteral Support in Endovascular Therapy for Acute Ischemic Stroke
NCT03737786 · View on ClinicalTrials.gov ↗
Study Summary
SEACOAST 1 is a prospective, randomized, blinded endpoint trial comparing collateral vigor and clinical outcomes, with different forms of GA in patients with acute ischemic stroke due to anterior circulation large vessel occlusion (LVO) undergoing mechanical thrombectomy. The study compares GA with normocarbia (GAN) versus GA with mild hypercarbia (GAH), with a primary outcome of collateral robustness at measured at catheter angiography and clinical efficacy as secondary outcome. It is anticipated that the SEACOAST 1 will be followed by a larger, pivotal trial, SEACOAST 2, with primary clinical endpoints, in which the best method of GA identified in SEACOAST 1 is compared with the alternative strategy of anesthesia care (MAC) with minimal or no sedation. The current study focuses uppn SEACOAST 1, which is to be conducted in University of California, Los Angeles Ronald Reagan Medical Center and Santa Monica Medical Center. All acute stroke patients who arrive to one of these two stroke centers and are deemed eligible for thrombectomy will be considered for the proposed study. Physician-investigators will determine study eligibility. Informed consent to participate in the study will be obtained from legally authorized representatives or competent patients. For non-competent patients without on-scene legally authorize representatives, the consent process will utilize enrollment in emergency circumstances with exemption of informed consent (EFIC).

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT03737786
The ClinicalTrials.gov registry entry for NCT03737786 describes a study currently listed as recruiting. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 90 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is University of California, Los Angeles, which has 829 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with Acute Stroke appearing as the primary indexed condition, and to 1 intervention — of which Tight control of end-tidal CO2 levels is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT03737786 reports 1 study location spanning 1 distinct geographic area — top geographies include California. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
