Effects of Butylphthalide Enhanced With Tenecteplase on Neurological Function in Mild Disabling Acute Ischemic Stroke

Abstract Background Intravenous thrombolysis is the cornerstone of early treatment for acute ischemic stroke (AIS), but some still have a poor prognosis, especially in patients with mild disabling stroke. Tenecteplase (TNK), a novel thrombolytic agent with favorable pharmacokinetic profiles, and butylphthalide (NBP), a multi-targeted neuroprotective drug, have shown promising efficacy in separate clinical applications. However, evidence for their combined use in mild disabling AIS is lacking. Aim To determine whether TNK combined with NBP can improve functional outcomes compared with TNK monotherapy in patients with mild disabling AIS who receive thrombolysis within 4.5 hours of onset. Design BENEFIT-2 is a prospective, multicenter, randomized, double-blind, active-controlled trial. Eligible patients are randomized 1:1 to receive either TNK plus NBP (combination group) or TNK plus placebo (control group) via stratified block randomization. The combination group receives sequential NBP sodium chloride injection (25mg/100ml, twice daily for 7 days) and oral NBP soft capsules (0.2g, three times daily) until day 14; the control group receives matching placebos. Eligibility criteria include age 18-80 years, onset time ≤4.5 hours, NIHSS score 2-5 with disabling manifestations (hemianopia, aphasia, or limb weakness), and pre-stroke modified Rankin Scale (mRS) score ≤1. Study outcomes The primary outcome is the proportion of patients with mRS score 0-1 at 90±7 days. Secondary out…
