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.

Optimizing Acute Ischemic Stroke Outcomes: The Role of Tenecteplase Before Mechanical Thrombectomy. Clin Ther 2024:S0149-2918(24)00223-6. [PMID: 39266330 DOI: 10.1016/j.clinthera.2024.08.014] [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: 03/16/2024] [Revised: 08/09/2024] [Accepted: 08/13/2024] [Indexed: 09/14/2024]
Abstract
PURPOSE Acute ischemic stroke (AIS) is a life-threatening condition demanding prompt reperfusion to salvage brain tissue. Thrombolytic drugs, like tenecteplase (TNK), offer clot dissolution, but time constraints and contraindications limit their use. Mechanical thrombectomy (MT) revolutionized AIS treatment, especially for large vessel occlusions (LVO). Recent evidence suggests that administering TNK before MT improves recanalization and outcomes, challenging the dominance of alteplase. METHODS Relevant articles focusing on TNK before MT were retrieved from PubMed, Scopus, and Web of Science, looking for randomized controlled trials (RCT), clinical trials, and meta-analyses in humans until 2024. FINDINGS TNK, a genetically engineered thrombolytic, exhibits superior fibrin specificity and a longer half-life than alteplase. Clinical trials comparing TNK and alteplase before MT showcase enhanced recanalization, functional outcomes, and safety with TNK. Advanced neuroimaging aids patient selection, though its cost-effectiveness warrants consideration. Dosing studies favor a 0.25 mg/kg dose for efficacy and reduced complications. Clinical guidelines from various associations acknowledge TNK's potential as an alteplase alternative for AIS treatment, particularly for LVOs eligible for thrombectomy. IMPLICATIONS In conclusion, TNK emerges as a promising option for bridging therapy in AIS, displaying efficacy and safety benefits, especially when administered before MT. Its fibrin specificity, longer half-life, and potential for improved outcomes position TNK as a viable alternative to alteplase, potentially transforming the landscape of AIS treatment strategies. While limitations like small sample sizes and variations in protocols exist, future research should focus on large-scale RCT, subgroup analyses, and cost-effectiveness evaluations to further elucidate TNK's role in optimizing AIS management.

Abstract
Intravenous thrombolysis (IVT) with tenecteplase or alteplase is the standard of care in, patients with Acute Ischemic Stroke (AIS) presenting within 3-4.5 h. However here, are no established guidelines for such treatment during pregnancy. We report a case, of AIS in third trimester of pregnancy successfully treated with Tenecteplase. To the, best of our knowledge, this is the first and only case of acute ischemic stroke in, pregnancy treated with Tenecteplase.

Abstract
INTRO Current guidelines for acute ischemic stroke recommend timely administration of intravascular thrombolytic therapy to promote functional and neurologic outcomes. Tenecteplase is an emerging off-label therapy for this indication and being utilized by various institutions due to its simpler administration strategy. In emergent situations in which intravenous access cannot be obtained, intraosseous access is a viable option for medication administration. However, there has been minimal published cases to support the efficacy and safety of intraosseous administration of tenecteplase for acute ischemic stroke. CASE We describe the case of a 51-year-old woman who developed acute ischemic stroke within our institution. Due to difficulty achieving intravenous access and time-dependent efficacy of thrombolytic therapy, the decision was made to administer tenecteplase by the intraosseous route. Stroke symptoms improved within 48 hours following administration without complication. CONCLUSION Intraosseous administration of tenecteplase may be considered for treatment of acute ischemic stroke if intravenous access is unattainable.

Abstract
OBJECTIVES There are limited data available demonstrating the safety and efficacy of intravenous tenecteplase versus alteplase in patients with acute ischemic stroke in the posterior circulation. MATERIALS AND METHODS This is a post-hoc analysis of the Alteplase compared to Tenecteplase (AcT) pragmatic, phase 3, registry-linked randomized controlled trial. Patients with any posterior circulation vessel occlusion on baseline imaging were included. Study outcomes included 90-day modified Rankin Scale (mRS) 0-1, mRS 0-2, ordinal mRS, death within 90 days, 24 h symptomatic intracerebral haemorrhage (sICH) and successful reperfusion/recanalization. Mixed effects regression adjusting for age, sex and stroke severity was used to analyze differences in outcomes between patients administered tenecteplase vs. alteplase. Further, sensitivity analysis was conducted for basilar artery occlusion (BAO) alone. RESULTS Of 1577 patients, 136 (8.6 %, 77:alteplase, 59:tenecteplase) had posterior circulation stroke. Baseline characteristics were similar[median age 71 (IQR 60-81) vs. 72 (IQR 65-82) years, 57.1 % vs. 67.8 % males, median baseline NIHSS 7 (IQR 4-12) vs. 7 (IQR 4-16) in alteplase vs. tenecteplase arms, respectively]. 28 patients (20.6 %, 16:alteplase, 12:tenecteplase arm) underwent EVT. The median 90-120 days mRS was 2 (IQR 1-4). There were no differences between alteplase and tenecteplase for 90-d mRS 0-1 (adjRR 0.93;95 %CI 0.63-1.36), 90-day mRS 0-2 (adjRR 0.95; 95 %CI 0.72-1.26), sICH (RR 0.65; 95 %CI 0.06-7.02) and mortality (RR 1.21; 95 %CI 0.61-2.38). Successful reperfusion eTICI 2b-3 and successful recanalization rAOL 2b-3 was achieved in 23/28 (82 %, 12:alteplase, 11:tenecteplase) and in 16/28 (57 %, 14:alteplase, 12:tenecteplase), respectively. Similar results were seen in 31 patients (22.8 %) with BAO. CONCLUSION Intravenous tenecteplase has a similar effect on outcome as alteplase, without increased safety concerns in patients with acute posterior circulation strokes.

Abstract
BACKGROUND Tissue plasminogen activator (tPA) is recommended as the preferred thrombolytic therapy for acute myocardial infarction (AMI). This study aimed to explore tPA-related adverse events (AEs) reported in the United States Food and Drug Administration Adverse Event Reporting System (FAERS), assess the potential safety of three preferred tPA therapies for treating AMI, and provide guidance for selecting tPA for prehospital thrombolysis. METHOD Four algorithms, including ROR, PRR, BCPNN, and MGPS, were used to quantify the signals of Tenecteplase, Reteplase, and Alteplase related AEs and compare the differential degrees of the three tPA-associated AEs in the actual data. RESULT We detected 18 signals of Tenecteplase-induced AE, 29 signals of Reteplase-induced AE, and 22 signals of Alteplase-induced AE. Among the three drugs, Tenecteplase had the highest signal intensity for intracranial hemorrhage-related AE, followed by Alteplase. Besides, Reteplase had the highest signal intensity for procedure-related AE and Alteplase had the highest signal intensity for arrhythmia-related AE. The time-onset analysis indicates that we should be vigilant for AEs, especially within the first week and the first 1-2 days after medication. CONCLUSION This study identified and compared the signals of AE related to Tenecteplase, Reteplase, and Alteplase in AMI patients.

Abstract
INTRODUCTION Previously published data are conflicting regarding the ability of tenecteplase versus alteplase to produce early recanalization of an intracranial large vessel occlusion. We compared the performance of each thrombolytic in a stroke network. METHODS We queried our prospectively collected code stroke registry for basilar, internal carotid, or proximal middle cerebral artery occlusion patients treated with intravenous thrombolysis from 11/17/2021-9/16/2023. The primary outcome was early recanalization, defined using angiographic or clinical criteria. Secondary and safety outcomes included 90-day functional independence and symptomatic intracranial hemorrhage. A multivariable regression analysis was performed to determine independent associations with the primary outcome. RESULTS 233 patients, with mean age 66.9 (16.6) years and median National Institutes of Health Stroke Scale score 15 (10-21), were included. One-hundred twenty-four of 233 (53.2 %) patients were treated with alteplase while 109/233 (46.8 %) were treated with tenecteplase. Endovascular thrombectomy was performed in 82 % of subjects. Early recanalization rates were similar between the groups (alteplase 22.6 %, tenecteplase 14.7 %; p = 0.14), as were rates of 90-day independent neurological function, symptomatic intracranial hemorrhage, and mortality. Patients with an internal carotid artery occlusion or with higher presenting stroke severity were less likely to achieve early recanalization. CONCLUSIONS Tenecteplase and alteplase have similar rates of early recanalization, 90-day functional independence, and safety outcomes in large vessel occlusion patients. Occlusion site and stroke severity predict response to thrombolysis. Future studies may investigate other factors associated with a positive response to thrombolytics as expanded treatment indications are explored.

Abstract
BACKGROUND Almost half of acute ischemic stroke patients present with mild symptoms and there are large practice variations in their treatment globally. Individuals with an intracranial occlusion who present with minor stroke are at an increased risk of early neurological deterioration and poor outcomes. Individual patient data meta-analysis in the subgroup of patients with minor deficits showed benefit of alteplase in improving outcomes; however, this benefit has not been seen with intravenous alteplase in published randomized trials. DESIGN TEMPO-2 (A Randomized Controlled Trial of Tenecteplase Versus Standard of Care for Minor Ischemic Stroke With Proven Occlusion) is a prospective, open label with blinded outcome assessment, randomized controlled trial, designed to test the superiority of intravenous tenecteplase (0.25 mg/kg) over nonthrombolytic standard of care, with an estimated sample size of 1274 patients. Adult patients presenting with acute ischemic stroke with the National Institutes of Health Stroke Scale (NIHSS) ⩽ 5 and visible arterial occlusion or perfusion deficit within 12 h of onset are randomized to receive either tenecteplase (0.25 mg/kg) or standard of care. The primary outcome is return to baseline neurological functioning, measured by the modified Rankin scale (mRS) at 90 days. Safety outcomes include death and symptomatic hemorrhage (intra or extra-cranial). Other secondary outcomes include mRS 0-1, mRS 0-2, ordinal shift analysis of the mRS, partial, and full recanalization on follow-up computed tomography angiogram. CONCLUSION Results of this trial will aid in determining whether there is benefit of using tenecteplase (0.25 mg/kg) in treating patients presenting with minor stroke who are at high risk of developing poor outcomes due to presence of an intracranial occlusion. DATA ACCESS STATEMENT Data will be available upon reasonable request.

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.

Abstract
BACKGROUND Tenecteplase (TNK) is considered a promising option for the treatment of acute ischemic stroke (AIS) with the potential to decrease door-to-needle times (DTN). This study investigates DTN metrics and trends after transition to tenecteplase. METHODS The Lone Star Stroke (LSS) Research Consortium TNK registry incorporated data from three Texas hospitals that transitioned to TNK. Subject data mapped to Get-With-the-Guidelines stroke variables from October 1, 2019 to March 31, 2023 were limited to patients who received either alteplase (ALT) or TNK within the 90 min DTN times. The dataset was stratified into ALT and TNK cohorts with univariate tables for each measured variable and further analyzed using descriptive statistics. Logistic regression models were constructed for both ALT and TNK to investigate trends in DTN times. RESULTS In the overall cohort, the TNK cohort (n = 151) and ALT cohort (n = 161) exhibited comparable population demographics, differing only in a higher prevalence of White individuals in the TNK cohort. Both cohorts demonstrated similar clinical parameters, including mean NIHSS, blood glucose levels, and systolic blood pressure at admission. In the univariate analysis, no difference was observed in median DTN time within the 90 min time window compared to the ALT cohort [40 min (30-53) vs 45 min (35-55); P = .057]. In multivariable models, DTN times by thrombolytic did not significantly differ when adjusting for NIHSS, age (P = .133), or race and ethnicity (P = .092). Regression models for the overall cohort indicate no significant DTN temporal trends for TNK (P = .84) after transition; nonetheless, when stratified by hospital, a single subgroup demonstrated a significant DTN upward trend (P = 0.002). CONCLUSION In the overall cohort, TNK and ALT exhibited comparable temporal trends and at least stable DTN times. This indicates that the shift to TNK did not have an adverse impact on the DTN stroke metrics. This seamless transition is likely attributed to the similarity of inclusion and exclusion criteria, as well as the administration processes for both medications. When stratified by hospital, the three subgroups demonstrated variable DTN time trends which highlight the potential for either fatigue or unpreparedness when switching to TNK. Because our study included a multi-ethnic cohort from multiple large Texas cities, the stable DTN times after transition to TNK is likely applicable to other healthcare systems.

Abstract
Both acute ischemic stroke (AIS) and pulmonary embolism (PE) are major causes of morbidity and mortality, with overlapping risk factors. Incidental or silent PE therefore may be discovered during an AIS work-up. Thrombolytic therapy is considered first-line therapy for eligible patients with AIS. We present the case of an 88-year-old man with an AIS, who was incidentally found to have a PE, and then received thrombolytic therapy leading to favorable outcomes in both conditions.

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.

Abstract
INTRODUCTION Data on prior use of Tenecteplase versus Alteplase in acute stroke management by mechanical thrombectomy are controversial. Our primary objective was to make a comprehensive comparative assessment of clinical and angiographic efficacy and safety outcomes in a large prospective observational study. METHODS We included stroke patients who were eligible for intravenous thrombolysis and endovascular thrombectomy between 2019 and 2021, from an ongoing registry in twenty comprehensive stroke centers in France. We divided patients into two groups based on the thrombolytic agent used (Alteplase vs Tenecteplase). We then compared their treatment times, and their angiographic (TICI scale), clinical (mRS at three months and sICH) and safety outcomes after controlling for potential confounders using propensity score methods. RESULTS We evaluated 1131 patients having undergone thrombectomy for the final analysis, 250 received Tenecteplase and 881 Alteplase. Both groups were of the same median age (75 vs 74 respectively), and had the same baseline NIHSS score (16) and ASPECTS (8). There was no significant difference for First Pass Effect (OR 0.93, 95 % CI 0.76-1.14, p = 0.75), time required for reperfusion (OR 0.03, 95 % CI 0.09-0.16, p = 0.49), or for final reperfusion status. Clinically, functional independence at 90 days was similar in both groups (OR 0.82, 95 % CI 0.61-1.10, p = 0.18) with the same risk of sICH (OR 1.36, 95 % CI 0.77-2.41, p = 0.28). However, Tenecteplase patients had shorter imaging-to-groin puncture times (99 vs 142 min, p < 0.05). CONCLUSIONS Tenecteplase showed no better clinical or angiographic impact on thrombectomy compared to Alteplase. Nevertheless, it appeared associated with a shorter thrombolysis-to-groin puncture time.

Abstract
The treatment of acute ischemic stroke has improved in last few decades. While meta-analyses of several trials have established the safety and efficacy of Intravenous (IV) Tenecteplase thrombolysis, concomitant continuous transcranial doppler (TCD) ultrasound administration has not been assessed in any clinical trial. The aim of this study was to determine the effects of continuous 2 MHz TCD ultrasound during IV Tenecteplase thrombolysis for Middle cerebral artery (MCA) stroke. A total of 19 patients were included, 13 received TCD ultrasound and 6 sham TCD with IV Tenecteplase. TCD spectrum and difference in Pre and post TCD parameters were measured. Asymptomatic hemorrhagic transformation of infarct was seen in two patients. There was no mortality or clinical worsening in the sonothrombolysis group as against sham sonothrombolysis group. Median of peak systolic velocity was increased in both the sonothrombolysis (P = 0.0002) and sham sonothrombolysis group (P-value = 0.001). The difference in change in mean flow velocity between two groups, sonothrombolysis (11 cm/sec) and sham sonothrombolysis (3.5 cm/sec) were also significantly different (P = 0.014). This pilot work has established safety of continuous 30 min TCD application along with IV Tenecteplase thrombolysis and it concludes that concomitant 2 MHz TCD ultrasound administration significantly increased the MCA blood flow compared to chemothrombolysis alone.CTRI Registered Number: CTRI/2021/02/031418.

Abstract
BACKGROUND Despite its increasing use, there are limited data on the risk of intracranial hemorrhage (ICH) after intravenous thrombolysis with tenecteplase in the setting of acute ischemic stroke. Our aim was to investigate the incidence and predictors of ICH after tenecteplase administration. METHODS We reviewed data from the prospective ongoing multicenter TETRIS (Tenecteplase Treatment in Ischemic Stroke) registry. Patients with available day-1 imaging were included in this study. Clinical, imaging and biological variables were collected. Follow-up imaging performed 24 h after IVT was locally reviewed by senior neuroradiologists and neurologists. The incidence of parenchymal hematoma (PH) and any ICH were investigated. Potential predictors of PH and any ICH were assessed in multivariable logistic regressions. Subgroup analyses focusing on patients intended for endovascular treatment were performed. RESULTS PH and any ICH occurred in 126/1321 (incidence rate: 9.5%, 95% CI 8.1-11.2) and 521/1321 (39.4%, 95% CI 36.8-42.1) patients, respectively. Symptomatic ICH was observed in 77/1321 (5.8%; 95% CI 4.7-7.2). PH occurrence was significantly associated with poorer functional outcomes (p < 0.0001) and death (p < 0.0001) after 3 months. Older age (aOR = 1.03; 95% CI 1.01-1.05), male gender (aOR = 2.07; 95% CI 1.28-3.36), a history of hypertension (aOR = 2.08; 95% CI 1.19-3.62), a higher baseline NIHSS (aOR = 1.07; 95% CI 1.03-1.10) and higher admission blood glucose level (aOR = 1.12; 95% CI 1.05-1.19) were independently associated with PH occurrence. Similar associations were observed in the subgroup of patients intended for endovascular treatment. CONCLUSION We quantified the incidence of ICH after IVT with tenecteplase in a real-life prospective registry and determined independent predictors of ICH. These findings allow to identify patients at high risk of ICH.

Tenecteplase versus alteplase for acute ischemic stroke: a systematic review and meta-analysis of randomized and non-randomized studies. J Neurol 2024; 271:2309-2323. [PMID: 38436679 DOI: 10.1007/s00415-024-12243-1] [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: 01/07/2024] [Revised: 02/07/2024] [Accepted: 02/07/2024] [Indexed: 03/05/2024]
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
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
BACKGROUND In recent years, there have anecdotal reports of intra-arterial thrombolysis (IAT) for the treatment of spinal cord ischemia (SCI) with encouraging results. We describe a patient with acute cervical SCI who underwent IAT with Tenecteplase at our institution. CASE PRESENTATION A 20-year-old man presented to the emergency department with a 12-hour history of progressive onset upper and lower extremity numbness, weakness, and urinary incontinence after sustaining a fall. MRI of cervical spine demonstrated T2 and STIR hyperintensity in the ventral aspect of the spinal cord spanning the C3, C4, and C5 levels suggestive of SCI. He demonstrated progression of neurologic deficits to C4 ASIA B spinal cord injury with complete loss of motor function, diminished sensation, and absent rectal tone. Emergent angiography was performed with prominent anterior spinal supply via the left ascending cervical artery. A total of 30 mg of Tenecteplase was administered intra-arterially in the bilateral vertebral arteries, bilateral ascending cervical arteries, and bilateral inferior thyroid arteries. Two-week post-intervention neurologic examination demonstrated improvement in injury level and severity. The patient was C6 ASIA C SCI, with 2/5 strength in the distal upper and lower extremities and improved sensation. CONCLUSION IAT with Tenecteplase may be a feasible option for the treatment of acute spinal cord ischemia in carefully selected patients.

Abstract
OBJECTIVES The aim of this study is to monitor, identify, and compare the adverse events (AEs) related to tenecteplase and alteplase, with the objective of exploring the potential safety of tenecteplase for acute ischemic stroke (AIS) and guiding its use to enhance patient safety. METHODS In order to evaluate the disproportionality of AEs associated with tenecteplase and alteplase in real-world data, four algorithms (ROR, PRR, BCPNN, EBGM) were utilized as measures to detect signals of AEs related to both drugs. Subsequently, Breslow-Day statistical analysis was applied to compare the RORs of the main system organ classes (SOCs) and key preferred terms (PTs) between tenecteplase and alteplase. RESULTS A statistical analysis was performed utilizing data gleaned from the Food and Drug Administration Adverse Event Reporting System (FAERS) database, encompassing 19,514,140 case reports from 2004Q1 to 2023Q1. There were 1,004 cases where tenecteplase was reported as the primary suspected (PS) and 2,363 tenecteplase-related adverse drug reactions (ADRs) at the PTs level were identified, the two data of alteplase were 10,945 and 25,266, respectively. The occurrence of drug-induced ADRs was analyzed across 27 organ systems, The analysis revealed several expected ADRs, such as Haemorrhage, Hypersensitivity which were consistent with the two drug-labels. It is of note that the signal strengths of 'death,' 'ventricular fibrillation,' 'cardiogenic shock' and 'pneumonia aspiration' at the PT level were markedly higher for tenecteplase than for alteplase, whereas the signal strength of 'angioedema' at the PT level was significantly higher for alteplase in comparison to tenecteplase. Additionally, unexpected significant ADRs associated with ocular adverse reactions and pneumonia aspiration at the PT level were identified, indicating potential AEs not currently mentioned in the drug instructions. CONCLUSION This study identified and compared signals of ADRs associated with tenecteplase and alteplase, although tenecteplase is as effective as alteplase and has advantages such as ease of use and affordability, it cannot replace alteplase in the treatment of AIS until its safety profile is fully recognized. Additionally, previously unreported ocular ADRs and pneumonia were identified, providing valuable insights into the relationship between ADRs and the use of these thrombolytic drugs. These findings underscore the importance of continuous monitoring and effective detection of AEs to ultimately enhance the safety of AIS patients undergoing thrombolytic therapy.

Abstract
BACKGROUND AND PURPOSE Tenecteplase is increasingly being used as a first-line treatment for acute ischemic stroke after several randomized studies demonstrated its safety and efficacy, resulting in a massive increase in the number of published studies on this topic. Our aim was to investigate the most impactful authors and relevant journals that have been instrumental in validating this treatment, in hopes of identifying objective research trends that may assist scientists, health organizations, and funding agencies to collaborate and plan future avenues of research. METHODS Using the search terms "Tenecteplase" and "Tenecteplase" AND "Stroke," 2683 and 1150 references were queried, respectively, using the abstract and citation database, Scopus. Scopus Citation Analysis was used to categorize the countries and authors who produced the most research. Metadata was retrieved and transferred to bibliographic visualization software, VOSviewer, for co-authorship and co-occurrence analyses to identify trends in tenecteplase research. RESULTS Data visualization software identified three tenecteplase research clusters - myocardial infarction, pulmonary embolism, and acute ischemic stroke. Our bibliographic analysis graphically identified that ischemic stroke currently leads both myocardial infarction and pulmonary embolism in annual publications pertaining to tenecteplase therapy, and further pinpointed perfusion imaging and wake-up strokes as the most relevant areas of study. The United States led all countries in tenecteplase publications, including exclusively stroke studies. The European Heart Journal led all journals in overall publications, while Stroke led all journals in stroke-related studies. CONCLUSIONS Through the use of bibliographic analysis and data visualization, we identified major articles and journals that reflected and shaped the current landscape of tenecteplase; recognized authors who engaged in tenecteplase research as it progressed from cardiopulmonary disease to stroke; and postulated future avenues of research.

Abstract
BACKGROUND Intravenous thrombolysis with tissue plasminogen activator is used for off-label treatment of acute childhood stroke. Tenecteplase (TNK) is used to treat acute stroke in adults at many institutions, although there are extremely few data about TNK use in children. We aimed to characterize pediatric stroke experts' experience and preferences with regard to TNK use in children with stroke. METHODS Online survey distributed to members of the International Pediatric Stroke Organization in April 2023. RESULTS We received 33 responses. Most (81.2%) respondents reported only being "a little familiar" or "somewhat familiar" with TNK. Only six (18%) respondents reported being "familiar" or "very familiar" with TNK. Seventy percent of respondents were willing to treat pediatric stroke with TNK, at least in some situations. In a hypothetical scenario of a child in an outside emergency room with only TNK available, 81.8% would consider recommending treatment with TNK. However, only three (9.1%) respondents had TNK in their stroke protocol and seven (21.2%) had TNK on formulary at their hospital. Two respondents reported direct awareness of a child treated with TNK. CONCLUSIONS The majority of pediatric stroke neurologists responding to this survey reported a willingness to consider TNK use in children. However, data on TNK use in children, provider experience, and pediatric hospital preparedness are limited.
