Abstract
OBJECTIVES Tenecteplase, a modified variant of alteplase with greater fibrin specificity and longer plasma half-life, may have better efficacy and safety than alteplase in patients with acute ischemic stroke (AIS). We aimed to compare the benefits and risks of tenecteplase versus alteplase in the treatment of AIS. METHODS Electronic databases were searched up to 10 February 2023 for randomized controlled trials evaluating the effect of tenecteplase versus alteplase in the treatment of AIS. The primary outcome was functional outcome at 90 days, and secondary outcomes including the symptomatic intracranial haemorrhage (SICH), and major neurological improvement. Subgroup analysis was performed based on the different dosage of tenecteplase. RESULTS Ten studies with a total of 5123 patients were analysed in this meta-analysis. Overall, no significant difference between tenecteplase and alteplase was observed for functional outcome at 90 days (excellent: OR 1.08, 95%CI 0.93-1.26, I2 = 26%; good: OR 1.04, 95%CI 0.83-1.30, I2 = 56%; poor: OR 0.95, 95%CI 0.75-1.21, I2 = 31%), SICH (OR 1.12, 95%CI 0.79-1.59, I2 = 0%), and early major neurological improvement (OR 1.26, 95%CI 0.80-1.96, I2 = 65%). The subgroup analysis suggested that the 0.25 mg/kg dose of tenecteplase had potentially greater efficacy and lower symptomatic intracerebral haemorrhage risk compared with 0.25 mg/kg dose tenecteplase. CONCLUSIONS Among AIS patients, there was no significant difference on clinical outcomes between tenecteplase and alteplase. Subgroup analysis demonstrated that 0.25 mg/kg doses of tenecteplase were more beneficial than 0.4 mg/kg doses of tenecteplase. Further studies are required to identify the optimal dosage of tenecteplase.

Lancet Neurol 2024; 23:775-786. [PMID: 38880118 DOI: 10.1016/s1474-4422(24)00206-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/17/2024] [Revised: 05/05/2024] [Accepted: 05/07/2024] [Indexed: 06/18/2024]
Abstract
BACKGROUND Intravenous tenecteplase increases reperfusion in patients with salvageable brain tissue on perfusion imaging and might have advantages over alteplase as a thrombolytic for ischaemic stroke. We aimed to assess the non-inferiority of tenecteplase versus alteplase on clinical outcomes in patients selected by use of perfusion imaging. METHODS This international, multicentre, open-label, parallel-group, randomised, clinical non-inferiority trial enrolled patients from 35 hospitals in eight countries. Participants were aged 18 years or older, within 4·5 h of ischaemic stroke onset or last known well, were not being considered for endovascular thrombectomy, and met target mismatch criteria on brain perfusion imaging. Patients were randomly assigned (1:1) by use of a centralised web server with randomly permuted blocks to intravenous tenecteplase (0·25 mg/kg) or alteplase (0·90 mg/kg). The primary outcome was the proportion of patients without disability (modified Rankin Scale 0-1) at 3 months, assessed via masked review in both the intention-to-treat and per-protocol populations. We aimed to recruit 832 participants to yield 90% power (one-sided alpha=0·025) to detect a risk difference of 0·08, with an absolute non-inferiority margin of -0·03. The trial was registered with the Australian New Zealand Clinical Trials Registry, ACTRN12613000243718, and the European Union Clinical Trials Register, EudraCT Number 2015-002657-36, and it is completed. FINDINGS Recruitment ceased early following the announcement of other trial results showing non-inferiority of tenecteplase versus alteplase. Between March 21, 2014, and Oct 20, 2023, 680 patients were enrolled and randomly assigned to tenecteplase (n=339) and alteplase (n=341), all of whom were included in the intention-to-treat analysis (multiple imputation was used to account for missing primary outcome data for five patients). Protocol violations occurred in 74 participants, thus the per-protocol population comprised 601 people (295 in the tenecteplase group and 306 in the alteplase group). Participants had a median age of 74 years (IQR 63-82), baseline National Institutes of Health Stroke Scale score of 7 (4-11), and 260 (38%) were female. In the intention-to-treat analysis, the primary outcome occurred in 191 (57%) of 335 participants allocated to tenecteplase and 188 (55%) of 340 participants allocated to alteplase (standardised risk difference [SRD]=0·03 [95% CI -0·033 to 0·10], one-tailed pnon-inferiority=0·031). In the per-protocol analysis, the primary outcome occurred in 173 (59%) of 295 participants allocated to tenecteplase and 171 (56%) of 306 participants allocated to alteplase (SRD 0·05 [-0·02 to 0·12], one-tailed pnon-inferiority=0·01). Nine (3%) of 337 patients in the tenecteplase group and six (2%) of 340 in the alteplase group had symptomatic intracranial haemorrhage (unadjusted risk difference=0·01 [95% CI -0·01 to 0·03]) and 23 (7%) of 335 and 15 (4%) of 340 died within 90 days of starting treatment (SRD 0·02 [95% CI -0·02 to 0·05]). INTERPRETATION The findings in our study provide further evidence to strengthen the assertion of the non-inferiority of tenecteplase to alteplase, specifically when perfusion imaging has been used to identify reperfusion-eligible stroke patients. Although non-inferiority was achieved in the per-protocol population, it was not reached in the intention-to-treat analysis, possibly due to sample size limtations. Nonetheless, large-scale implementation of perfusion CT to assist in patient selection for intravenous thrombolysis in the early time window was shown to be feasible.

Abstract
Background and Objectives With recent trials suggesting that endovascular thrombectomy (EVT) alone may be noninferior to combined intravenous thrombolysis (IVT) with alteplase and EVT and that tenecteplase is non-inferior to alteplase in treating acute ischemic stroke, we sought to understand current practices around the world for treating acute ischemic stroke with large vessel occlusion (LVO) depending on the center of practice (IVT-capable vs IVT and EVT-capable stroke center). Methods The electronic survey launched by the Practice Current section of Neurology: Clinical Practice included 6 clinical and 8 demographic questions. A single-case scenario was presented of a 65-year-old man presenting with right hemiplegia with aphasia with a duration of 1 hour. Imaging showed left M1-MCA occlusion with no early ischemic changes. The respondents were asked about their treatment approach in 2 settings: the patient presented to (1) the IVT-only capable center and (2) the IVT and EVT-capable center. They were also asked about the thrombolytic agent of choice in current and ideal circumstances for these settings. Results A total of 203 physicians (42.9% vascular neurologists) from 44 countries completed the survey. Most participants (55.2%) spent ≥50% of their time delivering stroke care. The survey results showed that in current practice, more than 90% of respondents would offer IVT + EVT to patients with LVO stroke presenting to either an EVT-capable (91.1%) or IVT-only-capable center (93.6%). Although nearly 80% currently use alteplase for thrombolysis, around 60% would ideally like to switch to tenecteplase independent of the practice setting. These results were similar between stroke and non-stroke neurologists. Discussion Most physicians prefer IVT before EVT in patients with acute ischemic stroke attributable to large vessel occlusion independent of the practice setting.

Abstract
BACKGROUND Tenecteplase is an effective thrombolytic agent for eligible patients with stroke who are treated within 4.5 hours after the onset of stroke. However, data regarding the effectiveness of tenecteplase beyond 4.5 hours are limited. METHODS In a trial conducted in China, we randomly assigned patients with large-vessel occlusion of the middle cerebral artery or internal carotid artery who had salvageable brain tissue as identified on perfusion imaging and who did not have access to endovascular thrombectomy to receive tenecteplase (at a dose of 0.25 mg per kilogram of body weight; maximum dose, 25 mg) or standard medical treatment 4.5 to 24 hours after the time that the patient was last known to be well (including after stroke on awakening and unwitnessed stroke). The primary outcome was the absence of disability, which was defined as a score of 0 or 1 on the modified Rankin scale (range, 0 to 6, with higher scores indicating greater disability), at day 90. The key safety outcomes were symptomatic intracranial hemorrhage and death. RESULTS A total of 516 patients were enrolled; 264 were randomly assigned to receive tenecteplase and 252 to receive standard medical treatment. Less than 2% of the patients (4 in the tenecteplase group and 5 in the standard-treatment group) underwent rescue endovascular thrombectomy. Treatment with tenecteplase resulted in a higher percentage of patients with a modified Rankin scale score of 0 or 1 at 90 days than standard medical treatment (33.0% vs. 24.2%; relative rate, 1.37; 95% confidence interval, 1.04 to 1.81; P = 0.03). Mortality at 90 days was 13.3% with tenecteplase and 13.1% with standard medical treatment, and the incidence of symptomatic intracranial hemorrhage within 36 hours after treatment was 3.0% and 0.8%, respectively. CONCLUSIONS In this trial involving Chinese patients with ischemic stroke due to large-vessel occlusion, most of whom did not undergo endovascular thrombectomy, treatment with tenecteplase administered 4.5 to 24 hours after stroke onset resulted in less disability and similar survival as compared with standard medical treatment, and the incidence of symptomatic intracranial hemorrhage appeared to be higher.

Abstract
INTRODUCTION United States stroke systems are increasingly transitioning from alteplase (TPA) to tenecteplase (TNK). Real-world data on the safety and effectiveness of replacing TPA with TNK before large vessel occlusion (LVO) stroke endovascular treatment (EVT) are lacking. METHODS Four Pennsylvania stroke systems transitioned from TPA to TNK during the study period 01/2020-06/2023. LVO stroke patients who received intravenous thrombolysis with TPA or TNK before EVT were reviewed. Multivariate logistic analysis was conducted adjusting for age, sex, National Institute of Health Stroke Scale (NIHSS), occlusion site, last-known-well-to-intravenous thrombolysis time, interhospital-transfer and stroke system. RESULTS Of 635 patients, 309 (48.7%) received TNK and 326 (51.3%) TPA prior to EVT. The site of occlusion was the M1 middle cerebral artery (MCA) (47.7%), M2 MCA (25.4%), internal carotid artery (14.0%), tandem carotid with M1 or M2 MCA (9.8%) and basilar artery (3.1%). A favorable functional outcome (90-day mRS ≤ 2) was observed in 47.6% of TNK and 49.7% of TPA patients (p = 0.132). TNK versus TPA groups had similar rates of early recanalization (11.9% vs. 8.4%, p = 0.259), successful endovascular reperfusion (93.5% vs. 89.3%, p = 0.627), symptomatic intracranial hemorrhage (3.2% vs. 3.4%, p = 0.218) and 90-day all-cause mortality (23.1% vs. 21.5%, p = 0.491). CONCLUSIONS This U.S. multicenter real-world clinical experience demonstrated that switching from TPA to TNK before EVT for LVO stroke resulted in similar endovascular reperfusion, safety, and functional outcomes.

J Neurol 2024; 271:3928-3941. [PMID: 38782799 PMCID: PMC11233346 DOI: 10.1007/s00415-024-12445-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2024] [Revised: 05/13/2024] [Accepted: 05/14/2024] [Indexed: 05/25/2024]
Abstract
BACKGROUND The benefits and risks of tenecteplase (TNK) versus alteplase (ALT) have recently been assessed in acute ischemic stroke (AIS) patients undergoing mechanical thrombectomy (MT) with diverse results. Due to its high fibrin specificity and lack of excitotoxicity, TNK may have a higher efficacy and safety profile. This study aimed to evaluate the benefits and risks of TNK compared to ALT in AIS patients prior to thrombectomy. METHODS We systematically searched four key databases, PubMed, Embase, Web of Science and Cochrane Library until January 27, 2024 for clinical studies evaluating the effects of TNK versus ALT in patients with large vessel occlusion undergoing MT. A random-effect meta-analysis was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. RESULTS Ten studies involving 3722 patients receiving TNK (1266 patients) or ALT (2456 patients) were included (age: 69.05 ± 14.95 years; 55.64% male). Compared to ALT-treated patients, TNK-treated patients demonstrated significantly higher rates of early recanalization (odds ratio 2.02, 95%-confidence interval 1.20-3.38, p = 0.008) without increased risk of symptomatic intracerebral hemorrhage (1.06, 0.64-1.76, p = 0.82) or intracerebral hemorrhage (1.21, 0.66-2.25, p = 0.54). TNK-treated patients showed similar rates of functional independence at 90 days (1.13, 0.87-1.46, p = 0.37) as ALT-treated patients, but lower rates of mortality within 90 days (0.65, 0.44-0.96, p = 0.03). CONCLUSION TNK is superior to ALT in achieving early recanalization and is associated with lower mortality within 90 days in AIS patients undergoing MT. Compared with ALT, TNK does not significantly alter functional independence at 90 days, symptomatic intracerebral hemorrhage or intracerebral hemorrhage.

Abstract
Stroke affects up to one in five people during their lifetime in some high-income countries, and up to almost one in two in low-income countries. Globally, it is the second leading cause of death. Clinically, the disease is characterised by sudden neurological deficits. Vascular aetiologies contribute to the most common causes of ischaemic stroke, including large artery disease, cardioembolism, and small vessel disease. Small vessel disease is also the most frequent cause of intracerebral haemorrhage, followed by macrovascular causes. For acute ischaemic stroke, multimodal CT or MRI reveal infarct core, ischaemic penumbra, and site of vascular occlusion. For intracerebral haemorrhage, neuroimaging identifies early radiological markers of haematoma expansion and probable underlying cause. For intravenous thrombolysis in ischaemic stroke, tenecteplase is now a safe and effective alternative to alteplase. In patients with strokes caused by large vessel occlusion, the indications for endovascular thrombectomy have been extended to include larger core infarcts and basilar artery occlusion, and the treatment time window has increased to up to 24 h from stroke onset. Regarding intracerebral haemorrhage, prompt delivery of bundled care consisting of immediate anticoagulation reversal, simultaneous blood pressure lowering, and prespecified stroke unit protocols can improve clinical outcomes. Guided by underlying stroke mechanisms, secondary prevention encompasses pharmacological, vascular, or endovascular interventions and lifestyle modifications.

Abstract
BACKGROUND Alteplase is the standard agent used in early reperfusion therapy, but alternative thrombolytic agents are needed. The efficacy and safety of reteplase as compared with alteplase in patients with acute ischemic stroke are unclear. METHODS We randomly assigned patients with ischemic stroke within 4.5 hours after symptom onset in a 1:1 ratio to receive intravenous reteplase (a bolus of 18 mg followed 30 minutes later by a second bolus of 18 mg) or intravenous alteplase (0.9 mg per kilogram of body weight; maximum dose, 90 mg). The primary efficacy outcome was an excellent functional outcome, defined as a score of 0 or 1 on the modified Rankin scale (range, 0 [no neurologic deficit, no symptoms, or completely recovered] to 6 [death]) at 90 days. The primary safety outcome was symptomatic intracranial hemorrhage within 36 hours after symptom onset. RESULTS A total of 707 patients were assigned to receive reteplase, and 705 were assigned to receive alteplase. An excellent functional outcome occurred in 79.5% of the patients in the reteplase group and in 70.4% of those in the alteplase group (risk ratio, 1.13; 95% confidence interval [CI], 1.05 to 1.21; P<0.001 for noninferiority and P = 0.002 for superiority). Symptomatic intracranial hemorrhage within 36 hours after disease onset was observed in 17 of 700 patients (2.4%) in the reteplase group and in 14 of 699 (2.0%) of those in the alteplase group (risk ratio, 1.21; 95% CI, 0.54 to 2.75). The incidence of any intracranial hemorrhage at 90 days was higher with reteplase than with alteplase (7.7% vs. 4.9%; risk ratio, 1.59; 95% CI, 1.00 to 2.51), as was the incidence of adverse events (91.6% vs. 82.4%; risk ratio, 1.11; 95% CI, 1.03 to 1.20). CONCLUSIONS Among patients with ischemic stroke within 4.5 hours after symptom onset, reteplase was more likely to result in an excellent functional outcome than alteplase.

Comparative efficacy and safety among different doses of tenecteplase for acute ischemic stroke: A systematic review and network meta-analysis. J Stroke Cerebrovasc Dis 2024; 33:107822. [PMID: 38897370 DOI: 10.1016/j.jstrokecerebrovasdis.2024.107822] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2024] [Revised: 05/28/2024] [Accepted: 06/13/2024] [Indexed: 06/21/2024] Open
Abstract
OBJECTIVES Tenecteplase (TNK) is a promising alternative to alteplase (ALT) as the thrombolytic agent for acute ischemic stroke (AIS). However, its clinical outcomes in certain populations remain unclear. This study aimed to compare the efficacy and safety among different doses of TNK in AIS patients. METHODS We searched PubMed, Scopus, Cochrane Central Register of Controlled Trials, and Embase for studies comparing at least one dose of TNK to another dose of TNK or ALT 0.90 mg/kg. We conducted Bayesian network meta-analyses to estimate the relative risks (RRs) and 95% credible intervals (CrIs) for all outcomes using ALT 0.90 mg/kg as the reference. The treatments were ranked according to their surface under the cumulative ranking (SUCRA) values. RESULTS We included 11 trials from 16 publications comprising 5423 participants. There were no significant differences between any doses of TNK and ALT for reperfusion, 3-month modified Rankin Score (mRS) 0-1 (rank 1st: TNK 0.25 mg/kg; SUCRA = 0.68), mRS 0-2 (rank 1st: TNK 0.25 mg/kg; SUCRA = 0.86), mortality (rank 1st: TNK 0.25 mg/kg; SUCRA = 0.82), intracranial hemorrhage (ICH) (rank 1st: TNK 0.25 mg/kg; SUCRA = 0.88), symptomatic ICH (sICH) (rank 1st: TNK 0.10 mg/kg; SUCRA = 0.70), and parenchymal hematoma (rank 1st: TNK 0.10 mg/kg; SUCRA = 0.68). TNK 0.40 mg/kg had a significantly higher sICH rate compared to TNK 0.25 mg/kg (RR = 2.39, 95% CrI = 1.00-7.92). Among elderly patients, TNK 0.25 mg/kg had a significantly lower rate of sICH than ALT 0.9 mg/kg (RR = 3.0 × 10-13, 95% CrI = 3.4 × 10-40-0.07). CONCLUSIONS TNK has efficacy and safety outcomes comparable to those of ALT. TNK 0.25 mg/kg may be the optimal dose of TNK for patients with AIS.

Tenecteplase versus standard of care for minor ischaemic stroke with proven occlusion (TEMPO-2): a randomised, open label, phase 3 superiority trial. Lancet 2024; 403:2597-2605. [PMID: 38768626 DOI: 10.1016/s0140-6736(24)00921-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/18/2024] [Revised: 04/24/2024] [Accepted: 04/30/2024] [Indexed: 05/22/2024]
Abstract
BACKGROUND Individuals with minor ischaemic stroke and intracranial occlusion are at increased risk of poor outcomes. Intravenous thrombolysis with tenecteplase might improve outcomes in this population. We aimed to test the superiority of intravenous tenecteplase over non-thrombolytic standard of care in patients with minor ischaemic stroke and intracranial occlusion or focal perfusion abnormality. METHODS In this multicentre, prospective, parallel group, open label with blinded outcome assessment, randomised controlled trial, adult patients (aged ≥18 years) were included at 48 hospitals in Australia, Austria, Brazil, Canada, Finland, Ireland, New Zealand, Singapore, Spain, and the UK. Eligible patients with minor acute ischaemic stroke (National Institutes of Health Stroke Scale score 0-5) and intracranial occlusion or focal perfusion abnormality were enrolled within 12 h from stroke onset. Participants were randomly assigned (1:1), using a minimal sufficient balance algorithm to intravenous tenecteplase (0·25 mg/kg) or non-thrombolytic standard of care (control). Primary outcome was a return to baseline functioning on pre-morbid modified Rankin Scale score in the intention-to-treat (ITT) population (all patients randomly assigned to a treatment group and who did not withdraw consent to participate) assessed at 90 days. Safety outcomes were reported in the ITT population and included symptomatic intracranial haemorrhage and death. This trial is registered with ClinicalTrials.gov, NCT02398656, and is closed to accrual. FINDINGS The trial was stopped early for futility. Between April 27, 2015, and Jan 19, 2024, 886 patients were enrolled; 369 (42%) were female and 517 (58%) were male. 454 (51%) were assigned to control and 432 (49%) to intravenous tenecteplase. The primary outcome occurred in 338 (75%) of 452 patients in the control group and 309 (72%) of 432 in the tenecteplase group (risk ratio [RR] 0·96, 95% CI 0·88-1·04, p=0·29). More patients died in the tenecteplase group (20 deaths [5%]) than in the control group (five deaths [1%]; adjusted hazard ratio 3·8; 95% CI 1·4-10·2, p=0·0085). There were eight (2%) symptomatic intracranial haemorrhages in the tenecteplase group versus two (<1%) in the control group (RR 4·2; 95% CI 0·9-19·7, p=0·059). INTERPRETATION There was no benefit and possible harm from treatment with intravenous tenecteplase. Patients with minor stroke and intracranial occlusion should not be routinely treated with intravenous thrombolysis.

Tenecteplase versus alteplase for acute ischaemic stroke in the elderly patients: a post hoc analysis of the TRACE-2 trial. Stroke Vasc Neurol 2024:svn-2023-003048. [PMID: 38858097 DOI: 10.1136/svn-2023-003048] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Accepted: 05/20/2024] [Indexed: 06/12/2024] Open
Abstract
BACKGROUND The benefit-risk profile of tenecteplase in the elderly patients with acute ischaemic stroke (AIS) is uncertain. We sought to investigate the efficacy and safety of 0.25 mg/kg tenecteplase compared with alteplase for AIS patients aged ≥80 years. METHODS We performed a post hoc analysis of the Tenecteplase Reperfusion Therapy in Acute Ischaemic Cerebrovascular Events-2 Trial, a randomised, phase 3, non-inferiority clinical trial. Disabling AIS patients aged ≥80 years who initiated intravenous thrombolytics within 4.5 hours of symptom onset were enrolled from June 2021 to May 2022 across 53 centres in China and were randomly allocated to receive 0.25 mg/kg tenecteplase or 0.9 mg/kg alteplase. The primary efficacy outcome was the proportion of participants with a modified Rankin Scale (mRS) score of 0-1 at 90 days. Symptomatic intracranial haemorrhage (sICH) within 36 hours was the safety outcome. RESULTS Of 137 participants, mRS 0-1 at 90 days occurred in 37 (49.3%) of 75 in the tenecteplase group vs 20 (33.9%) of 59 in the alteplase group (risk ratio (RR) 1.47, 95% CI 0.96 to 2.23). sICH within 36 hours was observed in 3 (4.0%) of 76 in the tenecteplase group and two (3.3%) of 61 in the alteplase group (RR 1.30, 95% CI 0.20 to 8.41). CONCLUSIONS The risk-benefit profile of tenecteplase thrombolysis was preserved in the elderly patients, which lends further support to intravenous 0.25 mg/kg tenecteplase as an alternative to alteplase in these patients.

Abstract
RATIONALE To date, the benefit of intravenous thrombolysis for acute ischemic stroke (AIS) patients without advanced neuroimaging selection is confined to within 4.5 h of onset. Our phase II EXIT-BT (Extending the tIme window of Thrombolysis by ButylphThalide up to 6 h after onset) trial suggested the safety, feasibility, and potential benefit of intravenous tenecteplase (TNK) in AIS between 4.5 and 6 h of onset. The EXIT-BT2 trial is a pivotal study undertaken to confirm or refute this signal. AIM To investigate the efficacy and safety of TNK for AIS between 4.5 and 6 h of onset with or without endovascular treatment. SAMPLE SIZE ESTIMATES A maximum of 1440 patients are required to test the superiority hypothesis with 80% power according to a two-sided 0.05 level of significance, stratified by age, sex, history of diabetes, location of vessel occlusion, baseline National Institute of Health stroke scale score, stroke etiology, and plan for endovascular treatment. DESIGN EXIT-BT2 is a prospective, randomized, open-label, blinded assessment of endpoint (PROBE), and multi-center study. Eligible AIS patients between 4.5 and 6 h of onset are randomly assigned 1:1 into a TNK group or control group. The TNK group will receive TNK (0.25 mg/kg, a single bolus over 5-10 s, maximum 25 mg). The control group will receive standard medical care in compliance with national guidelines for acute ischemic stroke. Both groups will receive standard stroke care from randomization to 90 days after stroke onset according to national guidelines. OUTCOME The primary efficacy endpoint is excellent functional outcome, defined as a modified Rankin Scale score 0-1 at 90 days after randomization, while the primary safety endpoint is symptomatic intracerebral hemorrhage, defined as National Institutes of Health Stroke Scale score increase ⩾4 caused by intracranial hemorrhage within 24 (-6/+12) h after randomization. CONCLUSIONS The results of EXIT-BT2 may determine whether intravenous TNK has a favorable risk/benefit profile in AIS between 4.5 and 6 h of onset.

Abstract
INTRODUCTION In intracranial medium-vessel occlusions (MeVOs), intravenous thrombolysis (IVT) shows inconsistent effectiveness and endovascular interventions remains unproven. We evaluated a new therapeutic strategy based on a second IVT using tenecteplase for MeVOs without early recanalization post-alteplase. PATIENTS AND METHODS This retrospective, comparative study included consecutively low bleeding risk MeVO patients treated with alteplase 0.9 mg/kg at two stroke centers. One center used a conventional single-IVT approach; the other applied a dual-IVT strategy, incorporating a 1-h post-alteplase MRI and additional tenecteplase, 0.25 mg/kg, if occlusion persisted. Primary outcomes were 24-h successful recanalization for efficacy and symptomatic intracranial hemorrhage (sICH) for safety. Secondary outcomes included 3-month excellent outcomes (modified Rankin Scale score of 0-1). Comparisons were conducted in the overall cohort and a propensity score-matched subgroup. RESULTS Among 146 patients in the dual-IVT group, 103 failed to achieve recanalization at 1 h and of these 96 met all eligible criteria and received additional tenecteplase. Successful recanalization at 24 h was higher in the 146 dual-IVT cohort patients than in the 148 single-IVT cohort patients (84% vs 61%, p < 0.0001), with similar sICH rate (3 vs 2, p = 0.68). Dual-IVT strategy was an independent predictor of 24-h successful recanalization (OR, 2.7 [95% CI, 1.52-4.88]; p < 0.001). Dual-IVT cohort patients achieved higher rates of excellent outcome (69% vs 44%, p < 0.0001). Propensity score matching analyses supported all these associations. CONCLUSION In this retrospective study, a dual-IVT strategy in selected MeVO patients was associated with higher odds of 24-h recanalization, with no safety concerns. However, potential center-level confounding and biases seriously limit these findings' interpretation. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT05809921.

Abstract
BACKGROUND Nearly half of patients with acute ischemic stroke who undergo intravenous thrombolysis (IVT) fail to achieve excellent functional outcomes. Early administration of tirofiban after IVT may improve patient outcomes. OBJECTIVE To evaluate the efficacy and safety of early tirofiban administration after intravenous tenecteplase in patients with acute ischemic stroke. METHODS AND DESIGN The ADVENT trial is a multicenter, randomized, parallel-controlled, double-blind clinical trial. A total of 1084 patients undergoing IVT without subsequent endovascular treatment will be recruited from multiple hospitals in China. Subjects will be randomized in a 1:1 ratio to receive tirofiban or placebo, which will be infused within 6 h after IVT until 24 h after IVT, at 0.4 μg/kg/min for 30 min and then at 0.1 μg/kg/min. The primary efficacy outcome is the proportion of patients with excellent functional outcomes (modified Rankin Scale (mRS) ⩽ 1) at 90 days. Secondary outcomes include the proportion of patients with favorable functional outcomes (mRS ⩽ 2) at 90 days and neurological functional assessments evaluated during hospitalization. Symptomatic intracranial hemorrhage will be the primary safety outcome. Mortality and other adverse events will be recorded. DISCUSSION This pivotal trial will provide important data on the early administration of antiplatelet therapy after IVT and may promote progress in treatment standards.

Abstract
Although intravenous thrombolysis with alteplase remains the primary treatment for acute ischemic stroke, tenecteplase has shown potential advantages over alteplase. Animal studies have demonstrated the favorable pharmacokinetics and pharmacodynamics of tenecteplase. Moreover, it is easier to administer. Clinical trials have demonstrated that tenecteplase is not inferior to alteplase and may even be superior in cases of acute ischemic stroke with large vessel occlusion. Current evidence supports the time and cost benefits of tenecteplase, suggesting that it could potentially replace alteplase as the main option for thrombolytic therapy, especially in patients with large vessel occlusion.

Abstract
BACKGROUND Tenecteplase is used as an alternative to alteplase and is considered noninferior for thrombolysis in acute ischemic stroke. OBJECTIVES To compare the effectiveness and adverse effects of tenecteplase and alteplase in the real-world management of acute ischemic stroke. MATERIALS AND METHODS In this retrospective observational study, we collected data from acute ischemic stroke patients admitted in six hospitals in West Bengal, India, and were thrombolysed with tenecteplase or alteplase between July 2021 and June 2022. Demographic data, baseline parameters, hospital course, and 3-month follow-up data were collected. The percentage of patients achieving a score of 0-2 in the modified Ranking scale at 3 months, rate of symptomatic intracranial hemorrhage, and all-cause mortality within 3 months were the main parameters of comparison between the two thrombolytic agents. RESULTS A total of 162 patients were initially included in this study. Eight patients were excluded due to unavailability of follow-up data. Among the remaining patients, 71 patients received tenecteplase and 83 patients received alteplase. There was no statistically significant difference between tenecteplase and alteplase with respect to the percentage of patients achieving functional independence (modified Rankin scale score 0-2) at 3 months (53.5% vs. 60.2%, P = 0.706), rate of symptomatic intracranial hemorrhage (5.6% vs. 10.8%, P = 0.246), and all-cause mortality at 3 months (11.3% vs. 15.7%, P = 0.628). CONCLUSION The effectiveness of tenecteplase is comparable to alteplase in the real-world management of acute ischemic stroke. Symptomatic intracranial hemorrhage and all-cause mortality rates are also similar in real-world practice.

Abstract
The landscape of acute ischemic stroke management has undergone a substantial transformation over the past 3 decades, mirroring our enhanced comprehension of the pathology and progress in diagnostic techniques, therapeutic interventions, and preventive measures. The 1990s marked a pivotal moment in stroke care with the integration of intravenous thrombolytics. However, the most significant paradigm shift in recent years has undoubtedly been the advent of endovascular thrombectomy. This article endeavors to deliver an exhaustive analysis of this revolutionary progression.

Abstract
OBJECTIVE Alteplase is the current standard of care for acute ischemic stroke. Tenecteplase is a newer fibrinolytic agent with preferable administration and lower costs; however, its comparative effectiveness to alteplase remains uncertain. We set out to perform a systematic review and meta-analysis to establish the benefits and harms of tenecteplase versus alteplase for acute ischemic stroke. METHODS We searched PubMed, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and ClinicalTrials.gov from inception to April 2023 for randomized and non-randomized studies that compared tenecteplase versus alteplase for acute ischemic stroke. Paired reviewers independently assessed risk of bias and extracted data. We performed both conventional meta-analyses and Bayesian network meta-analyses (NMA) with random-effects models and used the GRADE approach to evaluate the certainty of evidence. Our primary efficacy outcome was excellent functional outcome at 3 months, defined as a score of 0-1 on the modified Rankin Scale. Our primary safety outcomes were symptomatic intracranial hemorrhage and all-cause mortality. RESULTS Thirty-six studies were eligible for review, including 12 randomized (n = 5533) and 24 non-randomized studies (n = 44,956). Moderate certainty evidence showed that there was no difference between tenecteplase and alteplase in increasing the proportion of patients achieving excellent functional outcome at 3 months (odds ratio [OR], 1.10; 95% CI 0.98-1.23; risk difference [RD] 2.4%, 95% CI - 0.5 to 5.2), while moderate certainty evidence from NMA suggested that 0.25 mg/kg tenecteplase significantly improved excellent functional outcome at 3 months (OR, 1.16; 95% credible interval 1.02-1.32). Moderate certainty evidence showed that, compared to alteplase, tenecteplase may make little to no difference in the prevalence of symptomatic intracranial hemorrhage (OR, 1.12; 95% CI 0.79-1.59; RD 0.3%, 95% CI - 0.5 to 1.4), and probably reduces all-cause mortality (adjusted odds ratio [aOR], 0.44; 95% CI 0.30-0.64; RD - 4.6%; 95% CI - 5.8 to - 2.9). CONCLUSIONS Moderate certainty evidence suggested that there was little to no difference between tenecteplase and alteplase in increasing the proportion of patients achieving excellent functional outcome at 3 months and the risk of symptomatic intracranial hemorrhage, while compared to alteplase, tenecteplase probably reduce all-cause mortality. Administration of 0.25 mg/kg tenecteplase after acute ischemic stroke is suggestive of increasing the proportion of patients that achieve excellent functional outcome at 3 months.

Abstract
This study aims to investigate the association between HCT (Hematocrit) levels and adverse outcomes in patients with acute ischemic stroke (AIS) or transient ischemic attack (TIA); 14,832 participants from the China National Stroke Registry-III with AIS or TIA were analyzed. Participants were categorized into quartiles based on baseline HCT levels. The primary outcome was poor functional outcomes (modified Rankin Scale ≥ 3) during three months, with secondary outcomes including all-cause death, stroke recurrence, and combined vascular events. Logistic regression or Cox regression models were used to assess the relationship between HCT and clinical outcomes. Compared to the third quartile, patients in the lowest quartile group showed increased risk of poor functional outcome (adjusted OR: 1.35, 95% CI: 1.15-1.58, p < 0.001), patients in the lowest quartile had a higher risk of all-cause death (adjusted HR: 1.68, 95% CI: 1.06-2.68, p = 0.028), as did those in the highest quartile (adjusted HR: 2.02, 95% CI: 1.26-3.25, p = 0.004). Sensitivity analysis shows that the association of HCT with all-cause death weakened, while the association with poor functional outcome was strengthened after excluding patients with recurrent stroke. Our results indicated that HCT level could be used as a short-term predictor for poor functional outcomes and all-cause death in patients with AIS or TIA.

Abstract
BACKGROUND There is a significant burden of stroke in Asia. Asia has the largest population in the world in 2023, estimated at 4.7 billion. Approximately 9.5-10.6 million strokes will be anticipated annually in the backdrop of a diverse group of well-developed and less developed countries with large disparities in stroke care resources. In addition, Asian countries are in varying phases of epidemiological transition. SUMMARY In this review, we examined recent epidemiological features of ischaemic stroke and intracerebral haemorrhage in Asia with recent developments in hyperacute stroke reperfusion therapy and technical improvements in intracerebral haemorrhage. The article also discussed the spectrum of cerebrovascular diseases in Asia, which include intracranial atherosclerosis, intracerebral haemorrhage, infective aetiologies of stroke, moyamoya disease, vascular dissection, radiation vasculopathy, and cerebral venous thrombosis. KEY MESSAGES The review of selected literature and recent updates calls for attention to the different requirements for resources within Asia and highlights the breadth of cerebrovascular diseases still requiring further research and more effective therapies.

Abstract
PURPOSE Orolingual angioedema (OA) secondary to administration of thrombolytic therapy is a rare, but serious, known adverse effect. Despite the lack of robust evidence for their use, C1 esterase inhibitors are recommended by guidelines for the treatment of refractory thrombolytic-associated OA. This report highlights the use of a C1 esterase inhibitor in a patient with tenecteplase-associated OA unresolved by antihistamine and corticosteroid therapy. SUMMARY A 67-year-old white male with a history of hypertension managed with lisinopril presented to the emergency department with acute onset of slurred speech and left-sided hemiparesis. Following workup, an outside hospital's neurology stroke team suspected an acute infarct and determined the patient to be a candidate for tenecteplase. Approximately 1 hour after tenecteplase administration, the patient began complaining of dyspnea and mild oral angioedema. Immediate interventions for OA management included intravenous therapy with dexamethasone 10 mg, diphenhydramine 25 mg, and famotidine 20 mg. After an additional 30 minutes, the patient's OA symptoms continued to progress and a C1 esterase inhibitor (Berinert) was administered. Shortly after administration of the C1 esterase inhibitor, the patient's symptoms continued to worsen, ultimately leading to endotracheal intubation. Following intubation, symptom improvement was noted, and the patient was safely extubated after 30 hours. CONCLUSION Although rare, OA is a potentially life-threatening complication of tenecteplase therapy and requires prompt pharmacological intervention to optimize patient outcomes. Currently, no single agent or treatment algorithm exists that has shown significant efficacy or safety in the setting of thrombolytic-associated OA. Until data are available for C1 esterase inhibitors in this application, these inhibitors should only be considered if there is continued symptom progression after intravenous administration of corticosteroids and antihistamines.

Abstract
Background This retrospective observational cohort study aimed to evaluate whether tenecteplase's use for acute ischemic stroke (AIS) has time management advantages and clinical benefits. Methods 144 AIS patients treated with alteplase and 120 with tenecteplase were included. We compared baseline clinical characteristics, key reperfusion therapy time indices [onset-to-treatment time (OTT), door-to-needle time (DNT), and door-to-puncture time (DPT)] and clinical outcomes (24-h post-thrombolysis NIHSS improvement, and intracranial hemorrhage incidence) between the groups using univariate analysis. We assessed hospital stay durations and used binary logistic regression to examine tenecteplase's association with DNT and DPT target times, NIHSS improvement, and intracranial hemorrhage. Results Baseline characteristics showed no significant differences except hyperlipidemia and atrial fibrillation. OTT (133 vs. 163.72, p = 0.001), DNT (36.5 vs. 50, p < 0.001) and DPT (117 vs. 193, p = 0.002) were significantly faster in the tenecteplase group. The rates of DNT ≤ 45 min (65.83% vs. 40.44%, p < 0.001) and DPT ≤ 120 min (59.09% vs. 13.79%, p = 0.001) were significantly higher in the tenecteplase group. Tenecteplase was an independent predictor of achieving target DNT (OR 2.951, 95% CI 1.732-5.030; p < 0.001) and DPT (OR 7.867, 95% CI 1.290-47.991; p = 0.025). Clinically, the proportion NIHSS improvement 24 h post-thrombolysis was higher in the tenecteplase group (64.17% vs. 50%, p = 0.024). No significant differences were observed in symptomatic intracranial hemorrhage (sICH) or any intracranial hemorrhage (ICH). Patients receiving tenecteplase had shorter hospital stays (6 vs. 8 days, p < 0.001). Tenecteplase was an independent predictor of NIHSS improvement at 24 h (OR 1.715, 95% CI 1.011-2.908; p = 0.045). There was no significant association between thrombolytic choice and sICH or any ICH. Conclusion Tenecteplase significantly reduced DNT and DPT. It was associated with early neurological function improvement (at 24 h), without compromising safety compared to alteplase. The findings support tenecteplase's application in AIS.

Abstract
BACKGROUND We performed a review of acute stroke trials to determine features associated with premature termination of trial enrollment, defined by the authors as not meeting preplanned sample size. METHODS AND RESULTS MEDLINE was searched for randomized clinical stroke trials published in 9 major clinical journals between 2013 and 2022. We included randomized clinical trials that were phase 2 or 3 with a preplanned sample size ≥100 and a time-to-treatment within 24 hours of onset for transient ischemic attack, ischemic stroke, or intracerebral hemorrhage. Data were abstracted on trial features including trial design, inclusion criteria, imaging, location and number of sites, masking, treatment complexity, control group (standard therapy, placebo), industry involvement, and preplanned stopping rules (futility and efficacy). Least absolute shrinkage and selection operator regression was used to select the most important factors associated with premature termination; then, a multivariable logistic regression was fit including only the least absolute shrinkage and selection operator selected variables. Of 1475 studies assessed, 98 trials met eligibility criteria. Forty-five (46%) trials were prematurely terminated, of which 27% were stopped for benefit/efficacy, 20% for lack of money/slow enrollment, 18% for futility, 16% for newly available evidence, 17% for other reasons, and 4% due to harm. Complex trials (adjusted odds ratio [aOR], 2.76 [95% CI, 1.13-7.49]), presence of a futility rule (aOR, 4.43 [95% CI, 1.62-17.91]), and exclusion of prestroke dependency (none/slight disability only; aOR, 2.19 [95% CI, 0.84-6.72] versus dependency allowed) were identified as the strongest predictors. CONCLUSIONS Nearly half of acute stroke trials were terminated prematurely. Broadening inclusion criteria and simplifying trial design may decrease the likelihood of unplanned termination, whereas planned futility analyses may appropriately terminate trials early, saving money and resources.

Abstract
Background A number of clinical trials have compared tenecteplase (TNK) and alteplase for the management of acute ischemic stroke (AIS) and the results are inconsistent. Purpose Present systematic review and meta-analysis is undertaken to analyse the efficacy and safety of TNK in AIS compared to alteplase. Summary A thorough literature search was performed through the databases Embase, Cochrane Library, PubMed, and clinicaltrials.gov, for a period from inception to September 2022, with the keywords i.e., "tenecteplase" and "alteplase" and "acute ischemic stroke." Clinical trials published in English that compared the efficacy and safety of TNK to alteplase in AIS were included. The major outcomes of this meta-analysis were proportion of patients free from disability and functional independence at 90 days, early neurological improvement at 24 hours, all-cause mortality at 90 days, patients with intra cranial hemorrhage (ICH), and patients with severe disability at 90 days. A total of nine studies with 3,573 patients were included in the analysis. The proportion of patients with freedom from disability was comparable in both groups (relative risk [RR] = 1.04, 95 per cent CI = 0.92-1.17; p = .53). Similarly, proportion of patients with functional independence was comparable (RR = 1.12, 95 per cent CI = 0.96-1.31; p = .14). TNK group had a higher rate of early neurological recovery (RR = 1.56, 95 per cent CI = 0.96-2.54; p = .07). All-cause mortality at 90 days was comparable in both groups (RR = 0.97; 95 per cent CI = 0.72-1.29; p = .82). The proportion of patients with ICH was higher in TNK group (RR = 1.14, 95 per cent CI = 0.77-1.68; p = .52). The proportion of patients with severe disability was less in TNK group (RR =0.84, 95 per cent CI = 0.53-1.32; p = .44). Key Message TNK was similar to alteplase in terms of efficacy and safety. The patients in TNK group showed early neurological improvement but were simultaneously at higher risk of ICH. The TNK can be an alternative to alteplase if the benefits outweigh the risks.

Abstract
BACKGROUND Tenecteplase (TNK) is gaining recognition as a novel therapy for acute ischemic stroke (AIS). Despite TNK offering a longer half-life, time and cost saving benefits and comparable treatment and safety profiles to Alteplase (ALT), the adoption of TNK as a treatment for AIS presents challenges for hospital systems. OBJECTIVE Identify barriers and facilitators of TNK implementation at acute care hospitals in Texas. METHODS This prospective survey used open-ended questions and Likert statements generated from content experts and informed by qualitative research. Stroke clinicians and nurses working at 40 different hospitals in Texas were surveyed using a virtual platform. RESULTS The 40 hospitals had a median of 34 (IQR 24.5-49) emergency department beds and 42.5 (IQR 23.5-64.5) inpatient stroke beds with 506.5 (IQR 350-797.5) annual stroke admissions. Fifty percent of the hospitals were Comprehensive Stroke Centers, and 18 (45 %) were solely using ALT for treatment of eligible AIS patients. Primary facilitators to TNK transition were team buy-in and a willingness of stroke physicians, nurses, and pharmacists to adopt TNK. Leading barriers were lack of clinical evidence supporting TNK safety profile inadequate evidence supporting TNK use and a lack of American Heart Association guidelines support for TNK administration in all AIS cases. CONCLUSION Understanding common barriers and facilitators to TNK adoption can assist acute care hospitals deciding to implement TNK as a treatment for AIS. These findings will be used to design a TNK adoption Toolkit, utilizing implementation science techniques, to address identified obstacles and to leverage facilitators.

Abstract
BACKGROUND In recent years, Tenecteplase (TNK), a genetically modified variant of alteplase, has been verified as a potential substitute for alteplase in the reperfusion therapy of acute ischemic stroke (AIS). Given the emergence of new randomized controlled trials (RCTs) of this subject, a meta-analysis was conducted to evaluate the present comparative evidence regarding the efficacy and safety outcomes of TNK and alteplase in thrombolysis for AIS. METHODS Following predefined inclusion criteria, we searched the databases of PubMed, Web of Science, and Cochrane Library. RCTs satisfying our inclusion criteria were selected for meta-analysis. Outcome indicators were categorized into efficacy outcomes (early vessel recanalization, excellent recovery, good recovery and early neurological improvement) and safety outcomes (poor recovery, symptomatic intracerebral hemorrhage, parenchymal hemorrhage type 2(PH2) post thrombolysis, and mortality). We extracted data on efficacy outcomes and safety outcomes for patients with AIS in the TNK group at a dose of 0.25 mg/kg and the alteplase group at a dose of 0.9 mg/kg, and expressed the relative risks between the 2 groups as odds ratios (ORs) and 95% confidence intervals (CIs) using the Mantel-Haenszel method. For further insight, we performed a network meta-analysis using a Bayesian framework to compare different doses of TNK (0.1, 0.25, 0.32, and 0.4 mg/kg) with alteplase (0.9 mg/kg). RESULTS A total of 2994 patients in 9 RCTs comparing efficacy and safety outcomes in patients with AIS treated with TNK and alteplase were included. In a pairwise analysis of TNK 0.25 mg/kg and alteplase 0.9 mg/kg, regarding efficacy outcomes, the aggregated results show that TNK 0.25 mg/kg statistically significant increased early vessel recanalization (N = 368, TNK vs. alteplase, OR: 2.07,95%CI: [1.19,3.59], I2 = 0%) and excellent recovery (N = 3548, TNK vs. alteplase, OR: 1.15,95%CI: [1.01,1.32], I2 = 0%). There was no significant difference in good recovery (N = 3486, TNK vs. alteplase, OR: 1.38,95%CI: [0.89,2.15], I2 = 84%) or early neurological improvement (N = 1686, TNK vs. alteplase, OR: 1.06,95%CI: [0.87,1.28], I2 = 24%) between the TNK 0.25 mg/kg group and the alteplase 0.9 mg/kg group. In the safety outcomes, pooled results showed no significant difference in poor recovery (N = 3548, TNK vs. alteplase, OR: 0.94,95%CI: [0.81,1.10], I2 = 0%) and symptomatic intracerebral hemorrhage (N = 3567, TNK vs. alteplase, OR: 1.06,95%CI: [0.70,1.60], I2 = 0%) and PH2(N = 3103, TNK vs. alteplase, OR: 1.26,95%CI:[0.39,4.07], I2 = 56%)and mortality (N = 3447, TNK vs. alteplase, OR: 0.99,95%CI: [0.80,1.23], I2 = 33%) between the TNK group and the alteplase group. In a network meta-analysis, competing treatments were not significantly different from one another (TNK 0.1 mg/kg, TNK 0.25 mg/kg, TNK 0.32 mg/kg, TNK 0.4 mg/kg, alteplase 0.9 mg/kg) in either efficacy outcomes or safety outcomes. CONCLUSION In this analysis of 9 RCTs in patients with AIS, TNK 0.25 mg/kg was comparable to alteplase 0.9 mg/kg from the perspective of efficacy outcomes and safety outcomes after thrombolysis within 4.5 h of AIS occurrence.

Abstract
Alteplase (rtPA) remains the standard thrombolytic drug for acute ischemic stroke. However, new rtPA-derived molecules, such as tenecteplase (TNK), with prolonged half-lives following a single bolus administration, have been developed. Although TNK is currently under clinical evaluation, the limited preclinical data highlight the need for additional studies to elucidate its benefits. The toxicities of rtPA and TNK were evaluated in endothelial cells, astrocytes, and neuronal cells. In addition, their in vivo efficacy was independently assessed at two research centers using an ischemic thromboembolic mouse model. Both therapies were tested via early (20 and 30 min) and late administration (4 and 4.5 h) after stroke. rtPA, but not TNK, caused cell death only in neuronal cultures. Mice were less sensitive to thrombolytic therapies than humans, requiring doses 10-fold higher than the established clinical dose. A single bolus dose of 2.5 mg/kg TNK led to an infarct reduction similar to perfusion with 10 mg/kg of rtPA. Early administration of TNK decreased the hemorrhagic transformations compared to that by the early administration of rtPA; however, this result was not obtained following late administration. These two independent preclinical studies support the use of TNK as a promising reperfusion alternative to rtPA.

Abstract
BACKGROUND Carotid tandem lesions ((TL) ⩾70% stenosis or occlusion) account for 15-20% of acute stroke with large vessel occlusion. AIMS We investigated the safety and efficacy of intravenous tenecteplase (0.25 mg/kg) versus intravenous alteplase (0.9 mg/kg) in patients with carotid TL. METHODS This is a substudy of the alteplase compared with the tenecteplase trial. Patients with ⩾70% stenosis of the extracranial internal carotid artery (ICA) and concomitant occlusion of the intracranial ICA, M1 or M2 segments of the middle cerebral artery on baseline computed tomography angiography (CTA) were included. Primary outcome was 90-day-modified Rankin Scale (mRS) 0-1. Secondary outcomes were mRS 0-2, mortality, and symptomatic ICH (sICH). Angiographic outcomes were successful recanalization (revised Arterial Occlusive Lesion (rAOL) 2b-3) on first and successful reperfusion (eTICI 2b-3) on final angiographic acquisitions. Multivariable mixed-effects logistic regression was performed. RESULTS Among 1577 alteplase versus tenecteplase randomized controlled trial (AcT) patients, 128 (18.8%) had carotid TL. Of these, 93 (72.7%) underwent intravenous thrombolysis plus endovascular thrombectomy (IVT + EVT), while 35 (27.3%) were treated with IVT alone. In the IVT + EVT group, tenecteplase was associated with higher odds of 90-day-mRS 0-1 (46.0% vs. 32.6%, adjusted OR (aOR) 3.21; 95% CI = 1.06-9.71) compared with alteplase. No statistically significant differences in rates of mRS 0-2 (aOR 1.53; 95% CI = 0.51-4.55), initial rAOL 2b-3 (16.3% vs. 28.6%), final eTICI 2b-3 (83.7% vs. 85.7%), and mortality (18.0% vs. 16.3%) were found. SICH only occurred in one patient. There were no differences in outcomes between thrombolytic agents in the IVT-only group. CONCLUSION In patients with carotid TL treated with EVT, intravenous tenecteplase may be associated with similar or better clinical outcomes, similar angiographic reperfusion rates, and safety outcomes as compared with alteplase.

Abstract
Physical activity-induced mechanical stimuli play a crucial role in preserving bone mass and structure by promoting bone formation. While the Wnt pathway is pivotal for mediating the osteoblast response to loading, the exact mechanisms are not fully understood. Here, we found that mechanical stimulation induces osteoblastic Wnt1 expression, resulting in an upregulation of key osteogenic marker genes, including Runx2 and Sp7, while Wnt1 knockdown using siRNA prevented these effects. RNAseq analysis identified Plat as a major target through which Wnt1 exerts its osteogenic influence. This was corroborated by Plat depletion using siRNA, confirming its positive role in osteogenic differentiation. Moreover, we demonstrated that mechanical stimulation enhances Plat expression, which, in turn leads to increased expression of osteogenic markers like Runx2 and Sp7. Notably, Plat depletion by siRNA prevented this effect. We have established that Wnt1 regulates Plat expression by activating β-Catenin. Silencing Wnt1 impairs mechanically induced β-Catenin activation, subsequently reducing Plat expression. Furthermore, our findings showed that Wnt1 is essential for osteoblasts to respond to mechanical stimulation and induce Runx2 and Sp7 expression, in part through the Wnt1/β-Catenin/Plat signaling pathway. Additionally, we observed significantly reduced Wnt1 and Plat expression in bones from ovariectomy (OVX)-induced and age-related osteoporotic mouse models compared with non-OVX and young mice, respectively. Overall, our data suggested that Wnt1 and Plat play significant roles in mechanically induced osteogenesis. Their decreased expression in bones from OVX and aged mice highlights their potential involvement in post-menopausal and age-related osteoporosis, respectively.

Abstract
BACKGROUND AND PURPOSE Recombinant human TNK tissue-type plasminogen activator (rhTNK-tPA) was not inferior to alteplase for ischaemic stroke within 4.5 hours. Our study aimed to investigate the efficacy and safety of rhTNK-tPA in patients who had an ischaemic stroke due to large vessel occlusion (LVO) of anterior circulation beyond 4.5 hours. METHODS AND DESIGN Tenecteplase Reperfusion Therapy in Acute Ischaemic Cerebrovascular Events-III (TRACE III) is a multicentre, prospective, randomised, open-label, blind endpoint, controlled clinical trial. Patients who had an ischaemic stroke due to anterior circulation LVO (internal carotid artery, middle cerebral artery M1 and M2 segments) within 4.5-24 hours from last known well (including wake-up stroke and no witness stroke) and with salvageable tissue (ischaemic core volume <70 mL, mismatch ratio ≥1.8 and mismatch volume ≥15 mL) based on CT perfusion or MRI perfusion-weighted imaging (PWI) were included and randomised to rhTNK-tPA 0.25 mg/kg (single bolus) to a maximum of 25 mg or standard medical therapy. Specially, we will exclude patients who are intended for direct thrombectomy. All will be followed up for 90 days. STUDY OUTCOMES Primary efficacy outcome is modified Rankin Scale (mRS) score ≤1 at 90 days. Secondary efficacy outcomes include ordinal distribution of mRS at 90 days, major neurological improvement defined by a decrease ≥8 points compared with the initial deficit or a score ≤1 on the National Institutes of Health Stroke Scale (NIHSS) at 72 hours, mRS score ≤2 at 90 days, the rate of improvement on Tmax >6 s at 24 hours and NIHSS score change from baseline at 7 days. Safety outcomes are symptomatic intracerebral haemorrhage within 36 hours and mortality at 90 days. DISCUSSION TRACE III will provide evidence for the efficacy and safety of rhTNK-tPA in patients who had an ischaemic strokes due to anterior circulation LVO beyond 4.5 hours.

Abstract
BACKGROUND Thrombolytic agents, including tenecteplase, are generally used within 4.5 hours after the onset of stroke symptoms. Information on whether tenecteplase confers benefit beyond 4.5 hours is limited. METHODS We conducted a multicenter, double-blind, randomized, placebo-controlled trial involving patients with ischemic stroke to compare tenecteplase (0.25 mg per kilogram of body weight, up to 25 mg) with placebo administered 4.5 to 24 hours after the time that the patient was last known to be well. Patients had to have evidence of occlusion of the middle cerebral artery or internal carotid artery and salvageable tissue as determined on perfusion imaging. The primary outcome was the ordinal score on the modified Rankin scale (range, 0 to 6, with higher scores indicating greater disability and a score of 6 indicating death) at day 90. Safety outcomes included death and symptomatic intracranial hemorrhage. RESULTS The trial enrolled 458 patients, 77.3% of whom subsequently underwent thrombectomy; 228 patients were assigned to receive tenecteplase, and 230 to receive placebo. The median time between the time the patient was last known to be well and randomization was approximately 12 hours in the tenecteplase group and approximately 13 hours in the placebo group. The median score on the modified Rankin scale at 90 days was 3 in each group. The adjusted common odds ratio for the distribution of scores on the modified Rankin scale at 90 days for tenecteplase as compared with placebo was 1.13 (95% confidence interval, 0.82 to 1.57; P = 0.45). In the safety population, mortality at 90 days was 19.7% in the tenecteplase group and 18.2% in the placebo group, and the incidence of symptomatic intracranial hemorrhage was 3.2% and 2.3%, respectively. CONCLUSIONS Tenecteplase therapy that was initiated 4.5 to 24 hours after stroke onset in patients with occlusions of the middle cerebral artery or internal carotid artery, most of whom had undergone endovascular thrombectomy, did not result in better clinical outcomes than those with placebo. The incidence of symptomatic intracerebral hemorrhage was similar in the two groups. (Funded by Genentech; TIMELESS ClinicalTrials.gov number, NCT03785678.).

Safety and Efficacy of Reteplase Versus Alteplase for Acute Ischemic Stroke: A Phase 2 Randomized Controlled Trial. Stroke 2024; 55:366-375. [PMID: 38152962 DOI: 10.1161/strokeaha.123.045193] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Accepted: 12/05/2023] [Indexed: 12/29/2023]
Abstract
BACKGROUND Reteplase is a more affordable new-generation thrombolytic with a prolonged half-life. We aimed to determine the safety dose range of reteplase for patients with acute ischemic stroke within 4.5 hours of onset. METHODS This is a multicenter, prospective, randomized controlled, open-label, blinded-end point phase 2 clinical trial. Patients with acute ischemic stroke aged between 18 and 80 years who were eligible for standard intravenous thrombolysis were enrolled from 17 centers in China and randomly assigned (1:1:1) to receive intravenous reteplase 12+12 mg, intravenous reteplase 18+18 mg, or intravenous alteplase 0.9 mg/kg. The primary safety outcome was symptomatic intracranial hemorrhage (SITS definition) within 36 hours. The primary efficacy outcome was the proportion of patients with the National Institutes of Health Stroke Scale score of no more than 1 or a decrease of at least 4 points from the baseline at 14 days after thrombolysis. RESULTS Between August 2019 and May 2021, 180 patients were randomly assigned to reteplase 12+12 mg (n=61), reteplase 18+18 mg (n=67), or alteplase (n=52). Four patients did not receive the study agent. Symptomatic intracranial hemorrhage occurred in 3 of 60 (5.0%) in the reteplase 12+12 mg group, 1 of 66 (1.5%) in the reteplase 18+18 mg group, and 1 of 50 (2.0%) in the alteplase group (P=0.53). The primary efficacy outcome in the modified intention-to-treat population occurred in 45 of 60 (75.0%) in the reteplase 12+12 mg group (odds ratio, 0.85 [95% CI, 0.35-2.06]), 48 of 66 (72.7%) in the reteplase 18+18 mg group (odds ratio, 0.75 [95% CI, 0.32-1.78]), and 39 of 50 (78.0%) in alteplase group. CONCLUSIONS Reteplase was well tolerated in patients with acute ischemic stroke within 4.5 hours of onset in China with a similar efficacy profile to alteplase. The efficacy and appropriate dosage of reteplase for patients with acute ischemic stroke need prospective validation. REGISTRATION URL: https://www.clinicaltrials.gov; Unique identifier: NCT04028518.

Abstract
BACKGROUND AND PURPOSE Tenecteplase (TNK) has demonstrated non-inferiority to alteplase in patients who had an acute ischaemic stroke presenting within 4.5 hours from symptom onset. The trial is aimed to explore the efficacy and safety of TNK in Chinese patients who had an acute ischaemic stroke with large/medium vessel occlusion in an extended time window. METHODS AND DESIGN Chinese Acute Tissue-Based Imaging Selection for Lysis In Stroke Tenecteplase II (CHABLIS-T II) is a multicentre, prospective, block-randomised, open-label, blinded-endpoint, phase IIb study. Eligible patients are 1:1 randomised into two groups: 0.25 mg/kg TNK versus best medical management (excluding TNK). The safety and efficacy of 0.25 mg/kg TNK are assessed through reperfusion status and presence of symptomatic intracranial haemorrhage (sICH). STUDY OUTCOMES The primary outcome is major reperfusion without sICH at 24-48 hours after randomisation. Major reperfusion is defined as restoration of blood flow to greater than 50% of the involved ischaemic territory assessed by catheter angiography or repeated perfusion imaging. Secondary outcomes include post-thrombolytic recanalisation, neurological improvements, change in the National Institutes of Health Stroke Scale score, haemorrhagic transformation at 24-48 hours, systematic bleeding at discharge, modified Rankin Scale (mRS) 0-1, mRS 0-2, mRS 5-6, mRS distribution and Barthel index at 90 days. DISCUSSION CHABLIS-T II will provide important evidence of intravenous thrombolysis with TNK for patients who had an acute stroke in an extended time window.

Abstract
The only FDA-approved medical treatment for acute ischemic stroke (AIS) is alteplase (commonly referred to as "tPA"). The utilization of a newer fibrinolytic agent, tenecteplase, in routine stroke care is increasing because of recent clinical trial findings, streamlined clinical workflows, and cost-effectiveness. The stroke community is monitoring this development with considerable interest and special attention to the following questions: (1) Does the current evidence support superiority or noninferiority of tenecteplase compared with standard-of-care alteplase? (2) What are the ramifications of off-label treatment with tenecteplase? (3) And what are the real-world considerations when transitioning from alteplase to tenecteplase for AIS thrombolysis? This commentary provides a practical synthesis of the current evidence and discusses our institutional experience with tenecteplase including treatment considerations, off-label use, patient consent, stroke center accreditation, and cost savings. Necessary "Code Stroke" workflow changes to ensure a safe transition from alteplase to tenecteplase are detailed.

Abstract
Ischemic stroke (IS) causes severe disability and high mortality worldwide. Stem cell (SC) therapy exhibits unique therapeutic potential for IS that differs from current treatments. SC's cell homing, differentiation and paracrine abilities give hope for neuroprotection. Recent studies on SC modification have enhanced therapeutic effects for IS, including gene transfection, nanoparticle modification, biomaterial modification and pretreatment. These methods improve survival rate, homing, neural differentiation, and paracrine abilities in ischemic areas. However, many problems must be resolved before SC therapy can be clinically applied. These issues include production quality and quantity, stability during transportation and storage, as well as usage regulations. Herein, we reviewed the brief pathogenesis of IS, the "multi-mechanism" advantages of SCs for treating IS, various SC modification methods, and SC therapy challenges. We aim to uncover the potential and overcome the challenges of using SCs for treating IS and convey innovative ideas for modifying SCs.

Abstract
BACKGROUND The performance of intravenous tenecteplase in patients who had an acute ischaemic stroke with large/medium vessel occlusion or severe stenosis in an extended time window remains unknown. We investigated the promise of efficacy and safety of different doses of tenecteplase manufactured in China, in patients who had an acute ischaemic stroke with large/medium vessel occlusion beyond 4.5-hour time window. METHODS The CHinese Acute tissue-Based imaging selection for Lysis In Stroke-Tenecteplase was an investigator-initiated, umbrella phase IIa, open-label, blinded-endpoint, Simon's two-stage randomised clinical trial in 13 centres across mainland China. Participants who had salvageable brain tissue on automated perfusion imaging and presented within 4.5-24 hours from time of last seen well were randomised to receive 0.25 mg/kg tenecteplase or 0.32 mg/kg tenecteplase, both with a bolus infusion over 5-10 s. The primary outcome was proportion of patients with promise of efficacy and safety defined as reaching major reperfusion without symptomatic intracranial haemorrhage at 24-48 hours after thrombolysis. Assessors were blinded to treatment allocation. All participants who received tenecteplase were included in the analysis. RESULTS A total of 86 patients who had an acute ischaemic stroke identified with anterior large/medium vessel occlusion or severe stenosis were included in this study from November 2019 to December 2021. All of the 86 patients enrolled either received 0.25 mg/kg (n=43) or 0.32 mg/kg (n=43) tenecteplase, and were available for primary outcome analysis. Fourteen out of 43 patients in the 0.25 mg/kg tenecteplase group and 10 out of 43 patients in the 0.32 mg/kg tenecteplase group reached the primary outcome, providing promise of efficacy and safety for both doses based on Simon's two-stage design. DISCUSSION Among patients with anterior large/medium vessel occlusion and significant penumbral mismatch presented within 4.5-24 hours from time of last seen well, tenecteplase 0.25 mg/kg and 0.32 mg/kg both provided sufficient promise of efficacy and safety. TRIAL REGISTRATION NUMBER ClinicalTrials.gov Registry (NCT04086147, https://clinicaltrials.gov/ct2/show/NCT04086147).

Abstract
The use of biologics in various diseases has dramatically increased in recent years. Stroke, a cerebrovascular disease, is the second most common cause of death, and the leading cause of disability with high morbidity worldwide. For biologics applied in the treatment of acute ischaemic stroke, alteplase is the only thrombolytic agent. Meanwhile, current clinical trials show that two recombinant proteins, tenecteplase and non-immunogenic staphylokinase, are most promising as new thrombolytic agents for acute ischaemic stroke therapy. In addition, stem cell-based therapy, which uses stem cells or organoids for stroke treatment, has shown promising results in preclinical and early clinical studies. These strategies for acute ischaemic stroke mainly rely on the unique properties of undifferentiated cells to facilitate tissue repair and regeneration. However, there is a still considerable journey ahead before these approaches become routine clinical use. This includes optimising cell delivery methods, determining the ideal cell type and dosage, and addressing long-term safety concerns. This review introduces the current or promising recombinant proteins for thrombolysis therapy in ischaemic stroke and highlights the promise and challenges of stem cells and cerebral organoids in stroke therapy.

J Stroke Cerebrovasc Dis 2024; 33:107468. [PMID: 38039801 DOI: 10.1016/j.jstrokecerebrovasdis.2023.107468] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Revised: 10/20/2023] [Accepted: 11/03/2023] [Indexed: 12/03/2023] Open
Abstract
INTRODUCTION Tenecteplase has been compared to alteplase in acute stroke randomized trials, with similar outcomes and safety measures, but higher doses of tenecteplase have been associated with higher hemorrhage rates in some studies. Limited data are available on the safety of tenecteplase outside of clinical trials. METHODS We examined the safety measures of intracranial hemorrhage, angioedema, and serious extracranial adverse events in a 21-hospital integrated healthcare system that switched from alteplase (0.9 mg/kg, maximum dose 90 mg) to tenecteplase (0.25 mg/kg, maximum dose 25 mg) for acute ischemic stroke. RESULTS Among 3,689 subjects, no significant differences were seen between tenecteplase and alteplase in the rate of intracranial hemorrhage (ICH), parenchymal hemorrhage, or volume of parenchymal hemorrhage. Symptomatic hemorrhage (sICH) was not different between the two agents: sICH by NINDS criteria was 2.0 % for alteplase vs 2.3 % for tenecteplase (P = 0.57), and sICH by SITS criteria was 0.8 % vs 1.1 % (P = 0.39). Adjusted logistic regression models also showed no differences between tenecteplase and alteplase: the odds ratio for tenecteplase (vs alteplase) modeling sICH by NINDS criteria was 0.9 (95 % CI 0.33 - 2.46, P = 0.83) and the odds ratio for tenecteplase modeling sICH by SITS criteria was 1.12 (95 % CI 0.25 - 5.07, P = 0.89). Rates of angioedema and serious extracranial adverse events were low and did not differ between tenecteplase and alteplase. Elapsed door-to-needle times showed a small improvement after the switch to tenecteplase (51.8 % treated in under 30 min with tenecteplase vs 43.5 % with alteplase, P < 0.001). CONCLUSION In use outside of clinical trials, complication rates are similar between tenecteplase and alteplase. In the context of a stroke telemedicine program, the rates of hemorrhage observed with either agent were lower than expected based on prior trials and registry data. The more easily prepared tenecteplase was associated with a lower door-to-needle time.

Abstract
INTRODUCTION The drug most frequently used for thrombolysis in cases of acute ischemic stroke (AIS) is alteplase. However, there is moderate-to-high-quality evidence that tenecteplase has similar or higher efficacy and safety. With improved pharmacokinetic properties over alteplase, tenecteplase could be a significant advantage in treating AIS. AREAS COVERED After conducting an extensive search on Scopus and PubMed, this manuscript reviews and compares the pharmacokinetic properties of alteplase and tenecteplase. Additionally, it provides information on pharmacodynamics, clinical efficacy, safety, tolerability, and drug-drug interactions. EXPERT OPINION The pharmacokinetic profile of alteplase and tenecteplase is derived from studies in patients with acute myocardial infarction. Thanks to its pharmacokinetic properties, tenecteplase is the drug closest to being the ideal fibrinolytic for AIS. Its longer half-life enables a single-bolus administration, which is particularly useful in emergencies. Tenecteplase has proven to have a good efficacy and safety profile in randomized clinical trials. Although we are awaiting the results of the ongoing phase 3 randomized clinical trials, we believe that tenecteplase has the potential to revolutionize the treatment of AIS through thrombolysis.

Abstract
Tenecteplase (TNK), a newer fibrinolytic agent with greater fibrin specificity and longer half-life than alteplase, may has practical advantages over alteplase in acute ischemic stroke (AIS) thrombolysis. We aimed to perform a systematic review and meta-analysis of randomized controlled trials (RCTs) to compare different doses of TNK (0.1, 0.25, 0.4 mg/kg) and alteplase in acute ischemic stroke patients. We systematically searched PubMed, Embase and https://clinicaltrials.gov/ for RCTs comparing TNK with alteplase in this population eligible for thrombolysis. The Cochrane Risk of Bias Tool was used to assess study quality. Random-effects or fixed-effects meta-analysis models were used for evaluating all outcomes. Total 10 RCTs with 5097 patients were included. Compared with alteplase, TNK at doses of 0.25 mg/kg may associated with the greatest odds to achieve 90-day excellent independence (mRS score ≤1), but there were no significant differences between other doses of TNK (0.1 mg/kg and 0.4 mg/kg) and alteplase. Among secondary outcomes, no significant differences were found in functional outcome (mRS score ≤2) and mortality at 90 days between any dose of TNK and alteplase. Compared with alteplase, TNK was effective at doses of 0.1 mg/kg and 0.25 mg/kg without increased risk of symptomatic intracerebral hemorrhage (sICH), but patients treated with TNK 0.4 mg/kg showed increased odds of sICH. In conclusion, compared with alteplase, intravenous thrombolysis with TNK at dose of 0.25 mg/kg has a better efficacy and similar safety profile and is a reasonable option for patients with AIS.

Abstract
BACKGROUND Recently, a randomized controlled trial showed a beneficial effect of intra-arterial thrombolysis following successful endovascular thrombectomy (EVT) in patients with acute ischemic stroke due to large vessel occlusion in the anterior circulation. Due to differences in response to thrombolytics in occlusion of the posterior circulation, the purpose of ATTENTION IA is to explore the adjunct benefit of intra-arterial thrombolysis after successful recanalization in patients presenting with large and medium vessel occlusion of the posterior circulation. METHODS ATTENTION-IA is an investigator-initiated, multicenter, prospective, randomized clinical trial with open-label treatment and blinded endpoint assessment (PROBE). After achieving successful recanalization (expanded Thrombolysis In Cerebral Infarction (eTICI) 2b-3) of an occlusion of the vertebral, basilar, or posterior cerebral artery, patients will be randomized 1:1 to receive intra-arterial tenecteplase or standard of care. The primary effect parameter is a modified Rankin Score of 0-1 at day 90. RESULTS The trial recently completed enrollment, and data collection/verification is ongoing. The final results will be made available on completion of enrollment and follow-up. CONCLUSIONS ATTENTION-IA will provide definitive evidence for the efficacy and safety of adjunct intra-arterial tenecteplase after successful EVT in patients with an acute posterior circulation arterial occlusion stroke presenting within 24 hours of symptom onset. TRIAL REGISTRATION ClinicalTrials.gov NCT05684172.

Abstract
The management of acute ischemic stroke is changing. Over the period of 2010-2050, the number of incident strokes is expected to be more than double. Rapid access to mechanical thrombectomy for patients with large vessel occlusion is critically associated with their functional outcome. Moreover, patients with first pass effect had a better clinical outcome, lower mortality, and fewer procedural adverse events. We discuss some advances in acute ischemic stroke regarding the organization, the diagnosis and the treatment.
