Tenecteplase (TNK) is a promising alternative to alteplase (ALT) as the thrombolytic agent for acute ischemic stroke (AIS). However, its clinical outcomes in certain populations remain unclear. This study aimed to compare the efficacy and safety among different doses of TNK in AIS patients.
We searched PubMed, Scopus, Cochrane Central Register of Controlled Trials, and Embase for studies comparing at least one dose of TNK to another dose of TNK or ALT 0.90 mg/kg. We conducted Bayesian network meta-analyses to estimate the relative risks (RRs) and 95% credible intervals (CrIs) for all outcomes using ALT 0.90 mg/kg as the reference. The treatments were ranked according to their surface under the cumulative ranking (SUCRA) values.
We included 11 trials from 16 publications comprising 5423 participants. There were no significant differences between any doses of TNK and ALT for reperfusion, 3-month modified Rankin Score (mRS) 0-1 (rank 1st: TNK 0.25 mg/kg; SUCRA = 0.68), mRS 0-2 (rank 1st: TNK 0.25 mg/kg; SUCRA = 0.86), mortality (rank 1st: TNK 0.25 mg/kg; SUCRA = 0.82), intracranial hemorrhage (ICH) (rank 1st: TNK 0.25 mg/kg; SUCRA = 0.88), symptomatic ICH (sICH) (rank 1st: TNK 0.10 mg/kg; SUCRA = 0.70), and parenchymal hematoma (rank 1st: TNK 0.10 mg/kg; SUCRA = 0.68). TNK 0.40 mg/kg had a significantly higher sICH rate compared to TNK 0.25 mg/kg (RR = 2.39, 95% CrI = 1.00-7.92). Among elderly patients, TNK 0.25 mg/kg had a significantly lower rate of sICH than ALT 0.9 mg/kg (RR = 3.0 × 10, 95% CrI = 3.4 × 10-0.07).
TNK has efficacy and safety outcomes comparable to those of ALT. TNK 0.25 mg/kg may be the optimal dose of TNK for patients with AIS.
替奈普酶(TNK)是急性缺血性脑卒中(AIS)溶栓治疗的一种有前途的替代药物,优于阿替普酶(ALT)。然而,其在某些人群中的临床结局仍不清楚。本研究旨在比较不同剂量 TNK 在 AIS 患者中的疗效和安全性。
我们检索了 PubMed、Scopus、Cochrane 对照试验中心注册库和 Embase 中比较至少一种剂量 TNK 与另一种剂量 TNK 或 ALT 0.90mg/kg 的研究。我们使用 ALT 0.90mg/kg 作为参考,进行贝叶斯网络荟萃分析,以估计所有结局的相对风险(RR)和 95%可信区间(CrI)。根据累积排序概率(SUCRA)值对治疗方法进行排名。
我们纳入了 11 项来自 16 篇出版物的研究,共纳入 5423 名参与者。任何剂量的 TNK 与 ALT 相比,在再灌注、3 个月改良 Rankin 评分(mRS)0-1(排名第一:TNK 0.25mg/kg;SUCRA=0.68)、mRS 0-2(排名第一:TNK 0.25mg/kg;SUCRA=0.86)、死亡率(排名第一:TNK 0.25mg/kg;SUCRA=0.82)、颅内出血(ICH)(排名第一:TNK 0.25mg/kg;SUCRA=0.88)、症状性 ICH(sICH)(排名第一:TNK 0.10mg/kg;SUCRA=0.70)和脑实质血肿(排名第一:TNK 0.10mg/kg;SUCRA=0.68)方面均无显著差异。TNK 0.40mg/kg 的 sICH 发生率明显高于 TNK 0.25mg/kg(RR=2.39,95%CrI=1.00-7.92)。在老年患者中,TNK 0.25mg/kg 的 sICH 发生率明显低于 ALT 0.9mg/kg(RR=3.0×10,95%CrI=3.4×10-0.07)。
TNK 的疗效和安全性与 ALT 相当。TNK 0.25mg/kg 可能是 AIS 患者的最佳 TNK 剂量。
