Filter by:This study is designed to evaluate the safety, efficacy, and pharmacokinetics of balovaptan compared with placebo in participants with acute ischemic stroke (AIS) at risk of developing Malignant Cerebral Edema (MCE)
To examine the revascularization efficacy and safety of T-02 and its associated performance characteristics in treatment of appropriately selected subjects experiencing an acute ischemic stroke when the treatment is initiated within 24 hours after last seen well under the current guideline, and to generate hypotheses to be confirmed in subsequent confirmatory clinical investigations
This multi-center, randomized, parallel-group, double-blind, placebo-controlled study will evaluate the efficacy and safety of TB006 in participants with an Acute Ischemic Stroke (AIS) event with 57 days of treatment.
The investigators conduct this study to investigate whether oral administration of Dimethyl Fumarate, a Food and Drug Administration-approved drug for multiple sclerosis, is safe and effective in combination with intraarterial treatment in patients with Acute Ischemic Stroke.
We will recruit men and non-pregnant women of any ethnic background between the age ≥ 18 and ≤ 90 years that have acute ischemic stroke and underwent Mechanical Thrombectomy (MT) with TICI 2b or 2b following MT. These subject's will be will be randomized to placebo vs. Tirofiban after consent is obtained. This will be administered via continuous IV starting within 60 minutes of MT procedure completion. At the end of the 24 hour continuous IV dosing period a CT angiography and CT perfusion (CTA/CTP) will be obtained. The rest of the subjects inpatient hospital stay will be done per standard of care. The subject's NIHSS and modified Rankin Score (mRS) will be assessed at 90 days.
This study is designed to compare the safety, performance and efficacy of blood clot (thrombus) removal in subjects presenting with acute ischemic stroke with the NeVa versus the Solitaire stent retrievers.
This study is being conducted as a feasibility clinical investigation to collect safety and technical performance data of the WOLF Thrombectomy Device for the removal of thrombus in the neurovasculature.
The TRUST study is a non-interventional, prospective, multicenter, international, single arm and non-inferiority study. It is designed to evaluate the efficacy and safety of mechanical thrombectomy of the CATCHVIEW device compared to SOLITAIRE 2/FR based on an objective performance criterion (OPC) defined with available and published clinical evidence gathered through the Solitaire clinical trials in the arterial revascularization of patients with acute ischemic stroke.
This study will determine the safety of 500mg of aspirin added to IV TPA at standard doses to prevent re-occlusion of cerebral vessels after successful reperfusion. In ischemic stroke brain arteries are occluded either by an embolus originating in the heart or large vessels leading to the brain or by a process of acute thrombosis of the cerebral arteries over a ruptured atherosclerotic plaque. Rupture of the plaque exposes thrombogenic elements within the plaque and leads to accumulation and activation of platelets and induction of the clotting cascade eventually leading to acute thrombosis and occlusion of the artery. TPA is currently approved by the Food and Drug Administration to treat heart and brain problems caused by blockage of arteries. It activates plasminogen and leads to disintegration of the thrombus/embolus. It is effective only if begun within 3 to 4.5 hours of onset of the stroke because of potential deleterious side effects including life threatening symptomatic intracranial hemorrhage (sICH) when the drug is administered outside of this time window. Reperfusion of the ischemic brain (i.e. timely opening of the occluded artery) with TPA is associated with improved outcome. However, in about 33% of patients that have successfully reperfused after TPA the artery re-occludes within the first few hours resulting in worsening neurological symptoms and worse functional outcome. This re-occlusion is speculated to result from re-thrombosis over an existing ruptured atherosclerotic plaque. This is explained by the relatively short half life of TPA leaving the exposed ruptured plaque intact which leads to re-activation of platelets and clotting factors and re-thrombosis. Thus, we hypothesize that the addition of an antiplatelet agent to TPA would result in lower rates of re-occlusion after AIS. The FDA approved TPA for patients with AIS but discouraged the concomitant use of anti-platelet or anti-thrombotic drugs for the first 24hours after administration of TPA because of concerns that such therapy may result in increased rates of intracerebral hemorrhage. Aspirin is a well known platelet anti-aggregant that works by inhibition of cycloxygenase 1 and reduction in thromboxane A levels. It has a rapid onset of action and additional potential beneficial anti-inflammatory effects in patients with AIS. The international stroke study showed that acute treatment of stroke patients with 500mg of aspirin is safe and feasible and results in better outcome. Furthermore, the drug was safe in these circumstances with an ICH rate of only . Therefore, the purpose of this clinical trial is to examine the safety and efficacy of the combination of aspirin with rt-TPA in patients with AIS.
