Ischemic Post-conditioning in Acute Ischemic Stroke Thrombectomy (PROTECT-1b)
Acute Ischemic StrokeReperfusion InjuryIschemic post-conditioning is a neuroprotective strategy attenuating reperfusion injury in animal stroke models. The investigators have conducted a 3 + 3 dose-escalation trial to demonstrate the safety and tolerability of ischemic post-conditioning incrementally for a longer duration of up to 5 min × 4 cycles in stroke patients undergoing mechanical thrombectomy. This study aims to assess the infarct volume after ischemic post-conditioning in patients with acute ischemic stroke who are treated with mechanical thrombectomy.

Intra-arterial Thrombolysis After Successful Thrombectomy for Acute Ischemic Stroke in the Posterior...
Acute Ischemic StrokeArterial Thrombosis1 moreThe CHOICE study suggested that the use of adjunct intra-arterial alteplase after successful endovascular reperfusion in large vessel occlusion acute ischemic strokes may result in a greater likelihood of excellent neurological outcome at 90 days. However, CHOICE was a phase-2 trial and almost exclusively enrolled anterior circulation occlusions. Therefore, data on the safety and efficacy of post-endovascular reperfusion IAT in posterior circulation stroke is lacking. In general, anterior circulation strokes are associated with a higher risk of ICH than posterior circulation strokes. Therefore, we believe it might be safer to perform post-endovascular reperfusion IAT posterior circulation stroke. Also, there are more perforator artery in the posterior circulation, IAT would be more likely to show its benefit. Therefore, we would like to explore IA rt-PA for posterior circulation stroke after successful MT in our RCT.

Acute Ischemic StrokeLarge Vessel OcclusionThe objective of this study is to demonstrate the safety and efficacy of the Penumbra System including Thunderbolt Aspiration Tubing (Thunderbolt) in a population presenting with acute ischemic stroke (AIS) secondary to intracranial large vessel occlusion (LVO) who are eligible for mechanical thrombectomy.
Antiplatelet Effect of Ginkgo Diterpene Lactone Meglumine Injection in Acute Ischemic Stroke
Ischemic StrokeThis study evaluates the addition of Ginkgo Diterpene Lactone Meglumine Injection to aspirin in the treatment of acute ischemic stroke.Half of patient will receive Ginkgo Diterpene Lactone Meglumine Injection(25mg once/day D1-D14) and aspirin(100mg once/day D1-D14) in combination, while the other half will receive aspirin(100mg once/day D1-D14).
CERebrolysine Effect on Blood-brain Barrier in acUte Ischemic Stroke
Acute Ischemic StrokeThe study investigates whether Cerebrolysin stabilizes blood-brain barrier integrity in a manner that can be monitored using serum levels of the principal tight junction proteins, e.g., occludin (OCL), claudin-5 (CLN), and zonula occludens-1 (ZO-1), or other molecules known to be involved in BBB degradation, e.g., S100B and whether it protects against hemorrhagic transformation in ischemic stroke patients after reperfusion therapy (i.e. thrombolysis and/or mechanical thrombectomy).
A Study of NCS-01 in Patients With Acute Ischemic Stroke
Ischemic StrokeThis is an initial Phase1/2 dose-finding, randomized, multi-center study to evaluate the safety and tolerability of NCS-01 in patients with acute ischemic stroke. All patients will be randomized within 48 hours of stroke onset. This study will be conducted in 2 stages.
A Trial of Intravascular Hypothermia Therapy in Acute Ischemic Stroke Patients
HypothermiaReperfusion Injury2 moreAcute ischemic stroke (AIS) has been one of the major causes of global mortality and morbidity. The superiority of endovascular therapy (EVT) over standard medical therapy in treating AIS due to large vessel occlusion (LVO) in the anterior circulation has been widely accepted. However, a critical concern is that even with an extremely high rate of successful recanalization (the modified thrombolysis in cerebral infarction [mTICI] score 2b-3) around 90%, nearly half of the patients failed to benefit from EVT. So, adjunctive therapy of EVT for neuroprotection is required. From the previous domestic and foreign literatures, hypothermia can prevent and treat secondary injury caused by ischemia-reperfusion injury and cerebral edema of acute cerebral ischemia, so as to achieve the role of neuroprotection. In this study, intravascular cooling was performed as soon as possible with careful temperature control in patients receiving thrombectomy. The temperature was controlled at 33° C for 48-72 hours. This parallel controlled study is to systematically evaluate the feasibility and safety of adjunctive therapy using early intravascular hypothermia in AIS patients receiving mechanical thrombectomy. The results will clarify a potential modality for neuroprotection and hopefully provide new evidence in improving patient prognosis.
