Observational Study to Assess the Safety of rhTNK-tPA (Mingfule®) vs. Rt-PA (Actilyse®) in Treating Acute Ischemic Stroke

This is a multicenter, prospective, non-randomized, post-marketing safety surveillance cohort study with rt-PA (Actilyse®) as the control. It is designed to evaluate the safety of intravenous thrombolysis with recombinant human TNK tissue-type plasminogen activator (rhTNK-tPA, Mingfule®) compared with rt-PA (Actilyse®) in patients with acute ischemic stroke in the real-world setting. This is a non-interventional observational study with no randomization. Treatment decisions are made by treating physicians based on routine clinical practice and the patient's condition. Patients are naturally allocated to the rhTNK-tPA group or the rt-PA group according to the actual thrombolytic drug they receive.

Safety and Efficacy of Adjunctive GM1 to Mechanical Thrombectomy for Acute Anterior Circulation Large Vessel Occlusion

Stroke is a leading cause of global mortality and morbidity, with acute ischemic stroke (AIS) accounting for approximately 65.3% of cases and resulting in roughly 3.4 million new cases annually in China. While endovascular thrombectomy (EVT) is the recommended first-line therapy for large vessel occlusion (LVO), achieving 80-90% recanalization, fewer than 50% of patients reach functional independence (mRS 0-2) due to "futile recanalization" caused by mechanisms like no-reflow and reperfusion injury. Monosialotetrahexosylganglioside (GM1) is a unique glycosphingolipid that crosses the blood-brain barrier to provide neuroprotection by suppressing oxidative stress, excitotoxicity, and apoptosis while promoting neurogenesis. Although Phase III trials like the FOCUS study confirmed GM1's safety and efficacy in AIS populations, its benefit specifically for patients undergoing mechanical thrombectomy remains unkown. Therefore, the IAT-GIANT study is a multicenter, randomized, double-blind, placebo-controlled trial designed to evaluate the safety and efficacy of adjunctive GM1 in improving 90-day functional outcomes for AIS-LVO patients treated with EVT.

The Feasibility and Safety of RK-4 Injection Bypassing Blood-brain Barrier in the Treatment of Acute Large Hemispheric Infarction Using Intracalvariosseous Injection Device

The aim of this trial is to investigate the feasibility and safety of neuroprotective agent RK-4 injection using intracalvariosseous injection device in patients with acute large hemispheric infarction (LHI) who has contraindications of reperfusion therapy or have got poor reperfusion therapy outcomes.

Safety and Efficacy of J147 in Acute Ischemic Stroke

The goal of this clinical trial is to find out if the drug J147 improves outcomes for persons who have had an ischemic stroke. It also will learn about the safety of J147 when given by injection to stroke patients. Researchers will compare the outcomes of those who receive J147 after therapy to clear the blood clot to those who don't receive J147. Participants will be asked to undergo a series of three to four magnetic resonance imaging (MRI) brain scans, and blood samples will be collected at several time points. Participants will also be evaluated to measure several aspects of brain function.

Anisodine Hydrobromide for Patients With Acute Ischemic Stroke Undergoing Endovascular Therapy (HEAL)

The primary objective is to evaluate the safety and tolerability of the investigational intervention and to determine the recommended dose for subsequent clinical studies.

CGM in Acute Ischemic Stroke

The goal of this randomized clinical trial is to evaluate whether continuous glucose monitoring (CGM) can be used to guide glucose management in patients with type 2 diabetes who are admitted with an acute ischemic stroke and undergo endovascular therapy. Hyperglycemia frequently occurs during hospitalization in stroke and is associated with worse neurological and clinical outcomes. In current clinical practice, glucose levels are monitored using intermittent point-of-care testing (POCT) with finger-prick measurements, which may miss clinically relevant glucose fluctuations. CGM provides continuous glucose measurements and may allow earlier detection of hyperglycemia and more timely glucose management. This study is designed as a non-inferiority randomized controlled trial comparing CGM-guided glucose management with standard POCT-guided glucose management. The primary objective is to determine whether CGM-guided glucose management is non-inferior to POCT-guided management in terms of percentage time spent in hyperglycemia (glucose \>10 mmol/L) during the first 72 hours of hospitalization. Researchers will compare CGM-guided glucose management to POCT-guided glucose management to evaluate whether CGM can be used as an alternative strategy to guide glucose control in hospitalized stroke patients. Participants will: * Be randomly assigned to either CGM-guided glucose management or standard POCT-guided glucose management * Have their glucose levels continuously monitored (blinded in the POCT-guided group) during hospitalization * Receive glucose management according to the assigned monitoring strategy, based on the hospital insulin protocol

A Study to Test if Tenecteplase Helps People to Recover From an Acute Stroke When Given More Than 4.5 Hours After the Person Was Last Seen Well

This study is open to adults who had an acute stroke caused by a clot blocking a blood vessel in the brain (acute ischemic stroke). This study is for people who had an acute stroke or woke up with a stroke and were last seen well more than 4.5 hours before joining the study. Participants need to have imaging that shows there is brain tissue that can still be saved. They also should not be planned to receive a procedure to remove the blood clot. The purpose of this study is to find out whether a medicine called tenecteplase helps people recover from an acute stroke. Tenecteplase is already used to treat people within 4.5 hours after they had a stroke. This study tests if tenecteplase also helps if it is given more than 4.5 hours after the stroke. Participants are put into 2 groups randomly, which means by chance. One group gets tenecteplase as a single injection into a vein. The other group receives standard medical practice. Participants have an equal chance of receiving tenecteplase or the standard treatment. Participants are in the study for about 3 months. In the beginning, participants stay in the hospital for about 1 week. During the study, participants have 7 clinical examinations or visits. The last 2 of these visits will likely be done from home, allowing participants to complete certain assessments remotely. Doctors regularly test participants' recovery using a scale that measures the level of disability or dependence in daily activities. The results are compared between the 2 groups to see whether the treatment works. The doctors also check participants' health and take note of any unwanted effects.

Neurological deficit at the time of surgical treatment: the modified Rankin scale (mRs) score of 0-4 and the US National Institutes of Health (NIHSS) stroke scale score no more than 12 4. The size of the ischemia focus: no more than 1/3 in the territory of the middle cerebral artery brain supply 5. Terms of operation: from 1 to 28 days from the moment of ischemic stroke The primary intra-hospital and/or 30-day study endpoints: 1. Perioperative ipsilateral ischemic stroke. 2. Any stroke: contralateral ischemic or any hemorrhagic stroke. 3. Myocardial infarction. 4. Hemorrhagic complications that required surgical revision of the operating wound or transfusion of blood components. 5. Surgical site infection 6. Death 7. Main adverse cardiovascular events (stroke + myocardial infarction + death).

Safely Quenching Complement in Stroke Survivors

This study will include adults (ages 18-80) who have had a stroke caused by a large blood clot blocking blood flow in the brain. All patients in the study must have already had a treatment called a thrombectomy, where doctors remove the clot to help blood flow return to the brain. The goal of this study is to test the safety of a drug called EMPAVELI (pegcetacoplan). This drug is meant to lower swelling and inflammation that can happen after blood flow returns. The hope is that it may help protect the brain from more damage and improve recovery. People in the study will get three doses of EMPAVELI through an EMPAVELI-designed pump 0-3 hours post thrombectomy surgery and 24 and 48 hours after the initial dose. Doctors will check them with exams, blood tests, brain scans, and other tests while they are there. Patients will also have follow-up visits at 30 and 90 days to see how they are doing, per the usual standard of care. This research is important because, even with current stroke treatments, many patients still have problems like disability. If this drug is found to be safe, it could lead to better treatments to protect the brain and help people recover more fully after a stroke.

PeRforation EVents During ENdovascular Therapy for Acute Ischemic Stroke

A large, worldwide study called PREVENT is looking at a complication that can happen during a stroke treatment called thrombectomy. This complication is a perforation of a blood vessel. The investigators aim to: 1. Find what factors make this perforation more likely. 2. Understand why the perforation happens by looking closely at images taken during the procedure. 3. Create a simple way to classify these perforations to help doctors decide how to treat them right away. 4. Improve the emergent treatment of vessel perforation to stop the bleeding rapidly. 5. Provide data to guide decision whether thrombectomy should be continued or aborted after the event of vessel perforation. 6. Develop a safer way to perform thrombectomy. Investigators will compare the results collected for patients where perforation happened with those where perforation did not happen.
