Résumé
The current European Stroke Organisation expedited recommendation on tenecteplase (TNK) for acute ischemic stroke (AIS) advocates that TNK 0.25 mg/kg can be used alternatively to alteplase (tissue plasminogen activator [TPA]) for AIS of <4.5 hours duration, based on a meta-analytical approach establishing noninferiority. Since the publication of these guidelines, 4 additional randomized controlled clinical trials (RCTs) have provided further insight. We conducted an updated systematic review and meta-analysis including all available RCTs that investigated efficacy and safety of TNK 0.25 mg/kg compared with TPA for the treatment of AIS within 4.5 hours of onset. The primary outcome was defined as the excellent functional outcome at 3 months (modified Rankin Scale [mRS] score 0-1), whereas good functional outcome (mRS score 0-2), reduced disability at 3 months (≥1-point reduction across all mRS scores), symptomatic intracranial hemorrhage (sICH), and 3-month mortality were evaluated as secondary outcomes. Pooled estimates were calculated with random-effects model. A prespecified subgroup analysis was performed stratifying for TNK formulation, that is, original TNK vs biocopy: recombinant human TNK tissue-type plasminogen activator that is available in China and has a different production process. Eleven RCTs were included comprising a total of 3,788 patients treated with TNK vs 3,757 patients treated with TPA. TNK was associated with higher likelihood of excellent functional outcome (risk ratio [RR] 1.05, 95% CI 1.01-1.10; The updated meta-analysis confirms similar safety between TNK 0.25 mg/kg and TPA, while showing that TNK is superior to TPA regarding excellent functional outcome and reduced disability at 3 months. These findings support transitioning to TNK in clinical practice.

BACKGROUND AND OBJECTIVES
OBJECTIVE
The current European Stroke Organisation expedited recommendation on tenecteplase (TNK) for acute ischemic stroke (AIS) advocates that TNK 0.25 mg/kg can be used alternatively to alteplase (tissue plasminogen activator [TPA]) for AIS of <4.5 hours duration, based on a meta-analytical approach establishing noninferiority. Since the publication of these guidelines, 4 additional randomized controlled clinical trials (RCTs) have provided further insight.
METHODS
METHODS
We conducted an updated systematic review and meta-analysis including all available RCTs that investigated efficacy and safety of TNK 0.25 mg/kg compared with TPA for the treatment of AIS within 4.5 hours of onset. The primary outcome was defined as the excellent functional outcome at 3 months (modified Rankin Scale [mRS] score 0-1), whereas good functional outcome (mRS score 0-2), reduced disability at 3 months (≥1-point reduction across all mRS scores), symptomatic intracranial hemorrhage (sICH), and 3-month mortality were evaluated as secondary outcomes. Pooled estimates were calculated with random-effects model. A prespecified subgroup analysis was performed stratifying for TNK formulation, that is, original TNK vs biocopy: recombinant human TNK tissue-type plasminogen activator that is available in China and has a different production process.
RESULTS
RESULTS
Eleven RCTs were included comprising a total of 3,788 patients treated with TNK vs 3,757 patients treated with TPA. TNK was associated with higher likelihood of excellent functional outcome (risk ratio [RR] 1.05, 95% CI 1.01-1.10;
DISCUSSION
CONCLUSIONS
The updated meta-analysis confirms similar safety between TNK 0.25 mg/kg and TPA, while showing that TNK is superior to TPA regarding excellent functional outcome and reduced disability at 3 months. These findings support transitioning to TNK in clinical practice.
