Abstract

OBJECTIVE: Intravenous thrombolysis (IVT) with tenecteplase has been associated with better clinical outcomes in acute ischemic stroke (AIS) patients with confirmed large vessel occlusions compared to IVT with alteplase. However, the utility of tenecteplase for the treatment of all AIS patients eligible for IVT has not been established.

METHODS: We compared the safety and efficacy of tenecteplase versus alteplase in AIS patients by analyzing propensity score matched data from 20 centers participating in the Safe Implementation of Treatments in Stroke-International Stroke Thrombolysis Register. Patients receiving IVT with tenecteplase were matched with up to 3 patients receiving alteplase from the same center. The primary outcome of interest was the distribution of 3-month functional outcomes. Secondary outcomes included the rates of patients with symptomatic intracranial hemorrhage (SICH) in the first 24 hours, excellent (modified Rankin Scale [mRS] score = 0-1) or good (mRS score = 0-2) functional outcome, and all-cause mortality at 3 months.

RESULTS: A total of 331 tenecteplase-treated AIS patients were matched to 797 patients treated with alteplase (median age = 70 years, 43.9% women, median National Institutes of Health Stroke Scale score = 11, interquartile range = 6-17). Patients treated with tenecteplase had better 3-month functional outcomes (common odds ratio [OR] = 1.54, 95% confidence interval [CI] = 1.18-2.00) with higher odds of good functional outcome (OR = 2.00, 95% CI = 1.45-2.77) and a lower likelihood of all-cause mortality (OR = 0.43, 95% CI = 0.27-0.67) at 3 months, compared to alteplase-treated patients. No difference was found in the likelihood of the 3-month excellent functional outcomes (OR = 1.31, 95% CI = 0.96-1.78) and 24-hour SICH (1.0% vs 1.3%, OR = 0.72, 95% CI = 0.20-2.64).

INTERPRETATION: IVT with tenecteplase was associated with better 3-month clinical outcomes compared to IVT with alteplase in AIS patients, with no increased risk of symptomatic intracranial bleeding. ANN NEUROL 2022.
