Efficacy and Safety of Tenecteplase in Acute Ischemic Stroke: A Meta‐Analysis of Randomized Controlled Trials
Bibliographic record
Abstract
ABSTRACT Introduction Acute ischemic stroke (AIS) is the most common type of stroke, with increasing incidence and significant healthcare costs. Tenecteplase (TNK), a modified variant of tissue plasminogen activator (tPA), offers advantages such as a longer half‐life and single‐bolus administration. This meta‐analysis evaluates the safety and efficacy of TNK compared to non‐thrombolytic management in AIS to guide clinical decision‐making. Methodology A comprehensive literature search across major databases identified randomized controlled trials (RCTs) comparing tenecteplase with non‐thrombolytic care in ischemic stroke. Data extraction and bias assessment were conducted independently, using RoB 2.0 and the GRADE framework. Meta‐analysis was performed using RevMan 5.4.1, applying random‐effects models and assessing heterogeneity with the I 2 statistic. Results This meta‐analysis included seven studies with 3266 patients and found no significant difference between tenecteplase and standard medical care in terms of the mRS score at 90 days (mean difference = −0.16, p = 0.58), functional independence (mRS 0–2 at 90 days) (odds ratio = 1.07, p = 0.51), and reperfusion (TICI 2b‐3 at 24 h) (odds ratio = 1.33, p = 0.39). However, tenecteplase was associated with significantly higher mRS 0–1 at 90 days (odds ratio = 1.22, p = 0.01), better recanalization at 24 h (odds ratio = 3.28, p = 0.04), and improved NIHSS scores at 7 days (mean difference = −0.71, p = 0.003). On the downside, tenecteplase showed a significantly higher incidence of symptomatic intracranial hemorrhage (SICH) within 36 h (odds ratio = 2.24, p = 0.04) and any ICH (odds ratio = 1.40, p = 0.04), with no significant differences in mortality at 90 days (odds ratio = 1.18, p = 0.33) or stroke recurrence (odds ratio = 1.23, p = 0.55) and Barthel Index Score (odds ratio = 1.09, p = 0.69) and quality of life. Serious adverse events were slightly higher in the tenecteplase group but did not reach statistical significance (odds ratio = 1.18, p = 0.23). Conclusion Tenecteplase improves early neurological recovery and recanalization and provides excellent functional outcomes in acute ischemic stroke. However, it is associated with a higher risk of symptomatic and overall intracranial hemorrhage. Mortality, stroke recurrence, and overall functional independence remain unaffected.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
