Study 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.

Study arms

  • Experimental
    Albumin Group

    Subjects assigned to the albumin treatment group after achieving successful recanalization (eTICI ≥ 2b) confirmed by DSA post-thrombectomy will receive a 20% human albumin solution at a dose of 0.60 g/kg. The solution will be administered as a constant-rate infusion into the proximal internal carotid artery over 20 minutes. Vital signs and potential infusion-related reactions must be closely monitored throughout the procedure.

    Drug: Human serum albumin infusion 20%

  • No intervention
    Control Group

    Subjects in the control group who have achieved successful recanalization (eTICI ≥ 2b) as confirmed by DSA following mechanical thrombectomy will not receive the investigational infusion and will undergo standard medical management only.
