The efficacy and safety of tenecteplase versus alteplase for acute ischemic stroke: an updated systematic review, pairwise, and network meta-analysis of randomized controlled trials.

ABSTRACT: Tenecteplase (TNK) is a promising candidate to replace alteplase as the standard of care for acute ischemic stroke (AIS); however, the optimal dosage is still to be investigated. Therefore, we aim to evaluate the safety and efficacy of TNK versus alteplase and to investigate the optimal TNK dosage. A systematic review, pairwise, and network meta-analysis synthesizing randomized controlled trials (RCTs) from WOS, SCOPUS, EMBASE, and PubMed until July 26^th, 2022. We used the risk ratio (RR) for dichotomous outcomes presented with the corresponding 95% confidence interval (CI). We registered our protocol in PROSPERO with ID: CRD42022352038. Nine RCTs with a total of 3,707 patients were included. TNK significantly led to complete recanalization (RR: 1.27 with 95% CI [1.02, 1.57], P = 0.03); however, we found no difference regarding early neurological improvement (RR: 1.07 with 95% CI [0.94, 1.21], P = 0.33) and excellent neurological recovery (RR: 1.03 with 95% CI [0.96, 1.10], P = 0.42). Also, TNK was similar to alteplase regarding mortality (RR: 0.99 with 95% CI [0.82, 1.18], P = 0.88), intracranial haemorrhage (RR: 1.00 with 95% CI [0.85, 1.18], P = 0.99), and parenchymal hematoma (RR: 1.13 with 95% CI [0.83, 1.54], P = 0.44). TNK in the dose of 0.25 mg is a viable candidate to displace alteplase as the standard of care in patients with an AIS within 4.5 h of presentation due to its better rate of early neurological recovery and non-inferiority in terms of safety outcomes. However, the evidence regarding TNK's role in AIS presenting after 4.5 h from symptoms onset, wake-up stroke, and minor stroke/TIA is still lacking, necessitating further double-blinded pragmatic RCTs in this regard.

Project description:ImportanceTenecteplase is an alternative to alteplase for emergency treatment of acute ischemic stroke. However, limited data are available comparing their clinical effectiveness in routine clinical practice.ObjectiveTo compare short-term effectiveness and safety outcomes for patients with ischemic stroke treated with intravenous tenecteplase vs alteplase.Design, setting, and participantsThis comparative effectiveness study used data prospectively collected from July 1, 2020, through June 30, 2022, from the Get With The Guidelines-Stroke registry.ExposureConsecutive patients with ischemic stroke treated with either tenecteplase or alteplase within 4.5 hours from last known well time were included.Main outcomes and measuresThe primary end point was functional independence on discharge (modified Rankin Scale [mRS] score, 0-2). Secondary effectiveness end points included disability free at discharge (mRS score, 0-1), discharge home, and independent ambulation at discharge. Safety end points included symptomatic intracranial hemorrhage (sICH) within 36 hours and combined in-hospital mortality or hospice discharge. Generalized linear mixed models were fit to evaluate associations between exposure to tenecteplase (vs alteplase) and end points after adjustment for demographic, clinical, and hospital-level variables. Adjusted odds ratios (AORs) with 95% CIs were computed.ResultsAmong 79 550 patients treated with intravenous thrombolysis, the mean (SD) age was 68.6 (14.8) years, 38 596 (48.5%) were female, and the median National Institutes of Health Stroke Scale (NIHSS) score was 7 (IQR, 4-13). Of these patients, 9465 (11.9%) received tenecteplase (mean [SD] age, 69.6 [14.7] years; median NIHSS score, 7 [IQR, 4-14]; 4504 [47.6%] female) and 70 085 (88.1%) received alteplase (mean [SD] age, 68.5 [14.8] years; median NIHSS score, 7 [IQR, 4-13]; 34 092 [48.6%] female). After adjustment for covariates, no significant differences were found between tenecteplase and alteplase in effectiveness or safety outcomes for the overall cohort, including functional independence at discharge (AOR, 1.00; 95% CI, 0.93-1.07), sICH (AOR, 0.96; 95% CI, 0.83-1.11), and in-hospital mortality or hospice discharge (AOR, 0.98; 95% CI, 0.89-1.07), but significant improvement was found in discharge home (AOR, 1.26; 95% CI, 1.03-1.53), in-hospital mortality (AOR, 0.63; 95% CI, 0.47-0.85), and composite in-hospital mortality or hospice discharge (AOR, 0.78; 95% CI, 0.62-0.97) among those who were eligible for but did not undergo endovascular thrombectomy.Conclusions and relevanceThis large, nationwide comparative effectiveness study using data from routine clinical practice demonstrated similar effectiveness and safety outcomes with tenecteplase compared with alteplase in patients with acute ischemic stroke. This study supports tenecteplase as a reasonable alternative to alteplase.

Project description:BackgroundCarotid tandem lesions ((TL) ⩾70% stenosis or occlusion) account for 15-20% of acute stroke with large vessel occlusion.AimsWe investigated the safety and efficacy of intravenous tenecteplase (0.25 mg/kg) versus intravenous alteplase (0.9 mg/kg) in patients with carotid TL.MethodsThis 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.ResultsAmong 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.ConclusionIn 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.

Project description:Background and objectivesSeveral randomized controlled trials (RCTs) have compared tenecteplase to alteplase for treatment of acute ischemic stroke (AIS). Yet, there is no meta-analysis that includes the latest published RCTs of 2022. We sought to compare the safety and efficacy of tenecteplase vs. alteplase for the treatment of AIS through a meta-analysis of all published RCTs.MethodsA systematic literature review of the English language literature was conducted using PubMed, Web of Science, Scopus, and Embase. We included RCTs that focused on patients with AIS treated with tenecteplase and alteplase. Multiple reviewers screened through potential studies to identify the final papers included in our analysis. Following PRISMA guidelines, multiple authors extracted data to ensure accuracy. Data were pooled using a random-effects model.ResultsNine trials, with 3,706 patients, compared outcomes of patients treated with tenecteplase and alteplase for AIS. Both treatments resulted in comparable rates of modified Rankin Scale (mRS) 0-1 at 90 days (RR = 1.03; 95% CI = 0.97-1.10; P-value = 0.359) and mRS 0-2 at 90 days (RR = 1.03; 95% CI = 0.87-1.22; P-value = 0.749). There was no heterogeneity among included studies regarding mRS 0-1 rates (I2 = 26%; P-value = 0.211); however, there was significant heterogeneity in mRS 0-2 rates (I2 = 71%; P-value = 0.002). Similarly, rates of mortality (RR = 0.97; 95% CI = 0.81-1.16; P-value = 0.746) and symptomatic intracranial hemorrhage (sICH) rates (RR = 1.10; 95% CI = 0.75-1.61; P-value = 0.622) were comparable in both treatment groups. There was no significant heterogeneity among included studies in either mortality (I2 = 30%; P-value = 0.181) or sICH (I2 = 0%; P-value = 0.734) rates. Further analysis comparing dosing of tenecteplase (0.1, 0.25, 0.32, and 0.4 mg/kg) yielded no significant differences for any of the endpoints (mRS 0-1, mRS 0-2, sICH, and mortality) compared to alteplase.DiscussionBased on available evidence from completed RCTs, tenecteplase has proven similar safety and efficacy to alteplase for treatment of AIS.

Project description:ImportanceTenecteplase is a bioengineered variant of alteplase with greater fibrin specificity and a longer half-life, allowing single-bolus administration. Evidence on the treatment effect of tenecteplase 0.25 mg/kg in Chinese patients with acute ischemic stroke (AIS) is limited.ObjectiveTo establish the noninferiority of tenecteplase to alteplase in patients with AIS within 4.5 hours of symptom onset.Design, setting, and participantsThe ORIGINAL study was a multicenter, active-controlled, parallel-group, randomized, open-label, blinded end point, noninferiority trial conducted between July 14, 2021, and July 14, 2023. Participants were recruited from 55 neurology clinics and stroke centers in China and were eligible if they had AIS with a National Institutes of Health Stroke Scale score of 1 to 25 with measurable neurologic deficit and were symptomatic for at least 30 minutes without significant improvement.InterventionsPatients were randomized (1:1) within 4.5 hours of symptom onset to receive intravenous tenecteplase (0.25 mg/kg) or intravenous alteplase (0.9 mg/kg).Main outcomes and measuresThe primary outcome was the proportion of patients with a modified Rankin Scale (mRS) score of 0 or 1 (no symptoms or no significant disability) at day 90, tested for noninferiority (risk ratio [RR] margin, 0.937). Safety end points included symptomatic intracerebral hemorrhage (per European Cooperative Acute Stroke Study III definition) and 90-day all-cause mortality.ResultsAmong the 1489 patients randomized, 1465 patients were included in the full analysis set (732 in the tenecteplase group; 733 in the alteplase group) and 446 (30.4%) were female. The primary outcome occurred in 72.7% (532/732) of patients receiving tenecteplase and 70.3% (515/733) receiving alteplase (RR, 1.03 [95% CI, 0.97-1.09]; noninferiority threshold met). Symptomatic intracerebral hemorrhage occurred in 9 patients (1.2%) in each group (RR, 1.01 [95% CI, 0.37-2.70]). The 90-day mortality rate was 4.6% (34/732) in the tenecteplase group and 5.8% (43/736) in the alteplase group (RR, 0.80 [95% CI, 0.51-1.23]).Conclusions and relevanceIn patients with AIS eligible for intravenous thrombolysis within 4.5 hours after stroke onset, tenecteplase was noninferior to alteplase with respect to excellent functional outcome (mRS score of 0 or 1) at 90 days and had a similar safety profile. Findings from this study support tenecteplase as a suitable alternative to alteplase in this setting.Trial registrationClinicalTrials.gov Identifier: NCT04915729.
