The Preliminary Efficacy and Safety of Intra-Arterial Albumin as Adjunct to Mechanical Thrombectomy in Acute Ischemic Stroke
60 participantsStarted 2025-12-10
Plain-language summary
Albumin-assisted therapy has demonstrated good safety and potential neuroprotective effects following mechanical thrombectomy. To further systematically evaluate its efficacy and safety, we are conducting a Phase IIa clinical trial of intra-arterial albumin administration combined with mechanical thrombectomy in patients with acute ischemic stroke. This is a double-center, prospective, open-label, endpoint-blinded, randomized controlled trial designed to preliminarily assess the efficacy and safety of intra-arterial infusion of 20% human albumin after successful recanalization in patients with acute ischemic stroke caused by anterior circulation large-vessel occlusion who undergo mechanical thrombectomy. A total of 60 patients will be enrolled and randomized in a 1:1 ratio by dynamic minimization into two groups: the albumin group (0.6 g/kg of 20% human albumin solution plus mechanical thrombectomy) and the control group (mechanical thrombectomy alone).
The primary objective of this study is to preliminarily evaluate whether intra-arterial infusion of 0.6 g/kg of 20% human albumin via the internal carotid artery immediately after achieving successful recanalization (eTICI ≥ 2b) can reduce infarct volume compared with mechanical thrombectomy alone in patients with anterior circulation large-vessel occlusion who undergo standard mechanical thrombectomy. The secondary objective is to assess the safety and feasibility of intra-arterial infusion of 0.6 g/kg of 20% human albumin immediately after successful recanalization in this patient population.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
