Once again you will notice they are testing the wrong endpoints; 'good functional outcome' rather than 100% RECOVERY. THIS is why survivors need to be in charge, we won't take our eyes off the only goal in stroke: 100% RECOVERY.
Off-Label Use of Tenecteplase for the Treatment of Acute Ischemic Stroke
A Systematic Review and Meta-analysis
Question How does the use of tenecteplase compare with the use of alteplase in the clinical outcomes of patients with acute ischemic stroke (AIS) receiving intravenous thrombolysis?
Findings In this systematic review and meta-analysis, 6 nonrandomized studies including 1820 participants were analyzed. Intravenous tenecteplase was associated with better short-term and long-term functional outcomes in patients with AIS and a higher likelihood of successful recanalization in patients with acute intracranial vessel occlusions; no increased risk of intracranial bleeding was noted with intravenous tenecteplase compared with alteplase.
Meaning Analysis of evidence from nonrandomized studies suggests that tenecteplase is as safe as alteplase for the treatment of AIS and tenecteplase is potentially associated with more favorable outcomes.
Importance Tenecteplase is being evaluated as an alternative thrombolytic agent for the treatment of acute ischemic stroke (AIS) within ongoing randomized clinical trials (RCTs). In addition, nonrandomized clinical experiences with off-label use of tenecteplase vs alteplase for AIS treatment are being published.
Objective To evaluate the available evidence on the safety and efficacy of intravenous tenecteplase compared with intravenous alteplase provided by nonrandomized studies.
Data Sources Eligible studies were identified by searching MEDLINE and Scopus databases. No language or other restrictions were imposed. The literature search was conducted on October 12, 2021. This meta-analysis used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and was written according to the Meta-analysis of Observational Studies in Epidemiology (MOOSE) proposal.
Study Selection Nonrandomized studies (prospective or retrospective) comparing intravenous tenecteplase (at any dose) with intravenous alteplase in patients with AIS were included in the analysis.
Data Extraction and Synthesis The crude odds ratios (ORs) and 95% CIs were calculated for the association of tenecteplase vs alteplase with the outcomes of interest and adjusted ORs were extracted if provided. Estimates using random-effects models were pooled.
Main Outcomes and Measures The primary outcome was the probability of good functional outcome (modified Rankin scale [mRS] score, 0-2) at 90 days.
Results Six studies were identified including a total of 1820 patients (618 [34%] treated with tenecteplase). Patients receiving tenecteplase had higher odds of 3-month good functional outcome (crude odds ratio [OR], 1.22; 95% CI, 0.90-1.66; adjusted OR, 1.60, 95% CI, 1.08-2.37), successful recanalization (crude OR, 2.82; 95% CI, 1.12-7.10; adjusted OR, 2.38; 95% CI, 1.18-4.81), and early neurological improvement (crude OR, 4.88; 95% CI, 2.03-11.71; adjusted OR, 7.60; 95% CI, 1.97-29.41). No significant differences were detected in 3-month excellent functional outcome proportions (mRS score 0-1; crude OR, 1.53; 95% CI, 0.81-2.91; adjusted OR, 2.51; 95% CI, 0.66- 9.49), symptomatic intracranial hemorrhage (crude OR, 0.97; 95% CI, 0.44-2.16; adjusted OR, 1.16; 95% CI, 0.13-10.50), or parenchymal hematoma (crude OR, 1.20; 95% CI, 0.24-5.95).
Conclusions and Relevance Evidence from nonrandomized studies suggests tenecteplase is as safe as alteplase and potentially associated with improved functional outcomes compared with alteplase. Based on these findings, enrollment in the ongoing RCTs appears to be appropriate.
