Brief summary (registry, in English)
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.
