Rationale: The benefit of tenecteplase in the treatment of large vessel occlusion (LVO) patients presenting within 24 hours of symptom onset remains unclear.

Aim: To assess the effectiveness and safety of tenecteplase, compared to standard of care, in patients presenting within the first 24 hours of symptom onset with a LVO and target mismatch on perfusion CT.

Methods And Design: The "Extending the time window for Tenecteplase by Effective Reperfusion of peNumbrAL tissue in patients with Large Vessel Occlusion" (ETERNAL-LVO) trial is a prospective, randomized, open-label, blinded endpoint, phase 3, parallel-group, superiority trial with covariate-adjusted 1:1 randomization, and adaptive sample size re-estimation.

Objective: Telehealth paradigms are essential for remotely managing patients with chronic conditions. To assist clinicians in handling the large volumes of data collected through these systems, clinical decision support systems (CDSSs) have been developed. However, the effectiveness of CDSSs depends on the quality of remotely recorded physiological data and the reliability of the algorithms used for processing this data.

After stroke onset, ischemic brain tissue will progress to infarction unless blood flow is restored. Core growth rate measures the infarction speed from stroke onset. This multicenter cohort study aimed to explore whether core growth rate influences benefit from the reperfusion treatment of endovascular thrombectomy in large ischemic core stroke patients.

Article Synopsis
  • The study compared the effectiveness of intravenous tenecteplase and alteplase in treating ischaemic stroke patients identified as having salvageable brain tissue using perfusion imaging, focusing on whether tenecteplase is at least as effective (non-inferior) to alteplase in terms of patient outcomes after 3 months.
  • Conducted across 35 hospitals in eight countries, the trial enrolled 680 patients aged 18 and older, who were randomly assigned to receive either tenecteplase or alteplase, with the primary outcome being the rate of patients without disability measured through the modified Rankin Scale.
  • The trial was halted early due to positive results
