Intravenous Tenecteplase in Very Old Patients With Acute Ischemic Stroke

The benefit of intravenous tenecteplase in very old patients with acute ischemic stroke (AIS) remain uncertain. This real-world study aims to evaluate the effectiveness and safety of intravenous tenecteplase in AIS patients aged 80 years or older within 4.5 hours of symptom onset.

Unknown Time of Onset Stroke RePerfusIon Without Advanced Imaging

The benefit of intravenous tenecteplase for acute ischemic stroke with unknown time of onset, e.g. wake-up stroke, remains uncertain. This randomized study aims to assess the efficacy and safety of intravenous tenecteplase following non-contrast CT screening for acute ischemic stroke with unknown time of onset.

Intra-arterial Tenecteplase for Acute Medium Vessel Occlusion Stroke

The ANGEL-MeVO-TNK is a multicentered, prospective, randomized, open label, blinded endpoint (PROBE) phase III trial. A total of 488 AIS patients (age ≥18 years) with acute MeVO-AIS (occlusion of the M2/M3, the A1/A2/A3, the P1/P2/P3, and with baseline NIHSS score \>5 or disabling stroke with NIHSS score 3-5 \[such as neurological deficits in motor strength, language, vision, etc\]), will be enrolled. Patients fulfilling all the inclusion criteria and none of the exclusion criteria will be randomized 1:1 into the IA TNK group or the control group after offering informed content. * The IA TNK group will receive IA TNK (0.2-0.3 mg/min, for 15 -30min), be infused slowly. * The control group will be given standard medical management. The study consists of four visits including the day of randomization, 48±12 hours after randomization, and 90±7 days after randomization. Demographic information, symptoms and signs, laboratory test, neuro-imaging assessment neurological function rating scale will be recorded during the program. The primary outcome is the modified Rankin Scale (mRS) score of 0 to 1 at 90±7 days after onset. The primary safety outcome is the incidence of sICH within 48±12 hours after randomization (ECASS III).

Tenecteplase vs Medical Management in 4.5-24h LVO no Access to EVT

The goal of this clinical trial is to learn if tenectplase works to acute ischemic stroke (AIS) with onset 4.5-9 hours. It will also learn about the safety of tenectplase in AIS with onset 4.5-9 hours. The main question it aims to answer is: Does tenectplase improve the 90-days functional outcome in participants with acute large vessel occlusion? Researchers will compare tenectplase thrombolysis to non-use to see if tenectplase works to improve the functional outcome in participants with onset 4.5-9 hours. Participants will:\* Receive 0.25mg/kg (max 25mg) tenectplase at admission (after randomization) .\* Receive neurological assessment at admission, Day 5-7 or on hospital discharge (whichever earlier). Audio or video of the assessment may be recorded if possible.\* Receive brain CT + CT angiogram + CT perfusion and MRI after randomization, where the CT scan may be repetitive.

A Real-world Study of Tenecteplase Versus Alteplase for Thrombolysis in Patients Within 4.5 H of Onset of Ischemic Stroke

Stroke is the second leading cause of death worldwide, killing nearly 7 million people every year. Acute ischemic stroke is caused by focal cerebral hypoperfusion, usually due to embolism or atherosclerotic disease . Ischemic strokes account for 60-70% of all strokes worldwide and are severely debilitating, drawing considerable attention due to their high prevalence.The majority of studies comparing the efficacy and safety of teneplase and alteplase are predominantly randomized controlled trials with limited representation from real-world studies.The aim of this study is to compare the safety, efficacy and economic benefits of recombinant human TNK tissue plasminogen activator (tenecteplase, rhTNK-tPA, TNK) and recombinant tissue plasminogen activator (alteplase, rtPA) in clinical practice. This study aimed to establish a foundation for refining intravenous thrombolytic therapy tailored to various patient profiles and to guide clinicians in selecting the most suitable thrombolytic treatment options.
