Letter to the editor

Dear Editors,

In a recent issue of the American Journal of Cardiovascular Drugs, Ramakrishnan et al. [1] published their research on the efficacy and safety of bolus intravenous tenecteplase (TNK-tPA) in patients with acute ischemic stroke (AIS) arriving within 3 h of symptom onset. The authors conducted two open-label studies enrolling a total of 112 patients with AIS arriving within 3 h of onset of symptoms. Study 1 was an open-label randomized dose-finding preliminary study enrolling 50 eligible patients in which an intravenous bolus of TNK-tPA 0.1 mg/kg (20 patients) or 0.2 mg/kg (30 patients) was administered. Study 2 was a single-arm, open-label study enrolling 62 eligible patients in which an intravenous bolus of TNK-tPA 0.2 mg/kg was administered. The primary endpoint of both studies was an improvement of ≥ 8 points or a score of 0 on the National Institutes of Health Stroke Scale (NIHSS) (major neurological improvement) at 24 h. However, in study 2, for comparison with...
