Clinical Trial Summary

The purpose of this study is to investigate the safety and feasibility of intra-arterial albumin infusion for patients with acute ischemic stroke after successful thrombectomy and to further explore the optimal dose of albumin through the implementation of a 3 + 3 dose-escalation design.


Description:

Albumin, the predominant plasma protein synthesized primarily in the liver, possesses various biochemical properties that are expected to confer a neuroprotective effect following acute ischemic stroke. Despite being utilized as a neuroprotective agent for stroke patients, albumin has not demonstrated efficacy, partly due to the persistence of the occluded vessel responsible for the stroke, thereby hindering the albumin's ability to exert its therapeutic effects in the ischemic region. In light of the advent of thrombectomy and subsequent recanalization of occluded blood vessels, it is imperative to reassess the potential impact of albumin. In this study, we plan to conduct a 3 + 3 dose-escalation trial to determine the safety and feasibility of intra-arterial albumin infusion for stroke patients undergoing successful mechanical thrombectomy. Since this is a 3 + 3 dose-escalation study with 5 doses (0.25g/kg, 0.35g/kg, 0.40g/kg, 0.45g/kg, 0.5g/kg), a minimum of 15 (5 groups × 3 patient/group) patients will be required, assuming no major response occurs at any dose level, and a maximum of 30 (5 groups × 6 patient/group) patients will be required, assuming one major response occurs at each dose level. The present study is expected to provide the basis for subsequent phase 2 randomized control trials to explore the efficacy of intra-arterial albumin infusion.

Individuals with known allergies to albumin.

Study Design


Intervention

Biological:
Albumin
This is a 3 + 3 dose-escalation study with 5 doses (0.25g/kg, 0.35g/kg, 0.40g/kg, 0.45g/kg, 0.5g/kg). Intra-arterial albumin infusion will be applied after successful recanalization of the culprit artery in the anterior circulation.
