Abstract

Rationale Acute intracerebral hemorrhage inflicts a high-economic and -health burden. Computed tomography angiography spot sign is a predictor of hematoma expansion, is associated with poor clinical outcome and is an important stratifying variable for patients treated with haemostatic therapy. Aims We aim to compare the effect of treatment with tranexamic acid to placebo for the prevention of hemorrhage growth in patients with high-risk acute intracerebral hemorrhage with a positive spot sign. Design The tranexamic acid for acute intracerebral hemorrhage growth predicted by spot sign (TRAIGE) is a prospective, multicenter, placebo-controlled, double-blind, investigator-led, randomized clinical trial that will include an estimated 240 participants. Patients with intracerebral hemorrhage demonstrating symptom onset within 8 h and with the spot sign as a biomarker for ongoing hemorrhage, and no contraindications for antifibrinolytic therapy, will be enrolled to receive either tranexamic acid or placebo. The primary outcome measure is the presence of hemorrhage growth defined as an increase in intracerebral hemorrhage volume >33% or >6 ml from baseline to 24 ± 2 h. The secondary outcomes include safety and clinical outcomes. Conclusion The TRAIGE trial evaluates the efficacy of haemostatic therapy with tranexamic acid in the prevention of hemorrhage growth among high-risk patients with acute intracerebral hemorrhage.

摘要

理论依据 急性脑出血造成高昂的经济和健康负担。计算机断层血管造影斑点征是血肿扩大的预测指标,与不良临床结局相关,并且是接受止血治疗患者的重要分层变量。目的 我们旨在比较氨甲环酸与安慰剂治疗对具有阳性斑点征的高危急性脑出血患者预防出血扩大的效果。设计 斑点征预测急性脑出血用氨甲环酸治疗(TRAIGE)是一项前瞻性、多中心、安慰剂对照、双盲、研究者主导的随机临床试验,预计将纳入约240名参与者。脑出血患者症状发作在8小时内,且斑点征作为持续出血的生物标志物,并且无抗纤维蛋白溶解治疗禁忌证,将被纳入接受氨甲环酸或安慰剂治疗。主要结局指标是出血扩大的存在情况,定义为从基线到24±2小时脑出血体积增加>33%或>6毫升。次要结局包括安全性和临床结局。结论 TRAIGE试验评估氨甲环酸止血治疗在预防高危急性脑出血患者出血扩大方面的疗效。
