研究目的:

主要目的:评估注射用重组人尿激酶原相比阳性对照药阿替普酶治疗急性ST段抬高型心肌梗死的有效性。 次要目的:评估注射用重组人尿激酶原治疗急性ST段抬高型心肌梗死的安全性及临床开通率。 (1)按照临床指标判断的给予溶栓药物后的梗死相关动脉再通率; (2)溶栓后30天内的临床MACCE事件发生率; (3)出血性事件发生率。  

Objectives of Study:

Primary Objective: To evaluate the efficacy of recombinant human prourokinase for injection versus alteplase (the positive control) in the treatment of acute ST-segment elevation myocardial infarction (STEMI). Secondary Objective: To evaluate the safety and clinical reperfusion rate of recombinant human prourokinase for injection in the treatment of acute ST-segment elevation myocardial infarction (STEMI). (1) Reperfusion rate of the infarct-related artery after thrombolytic agent administration, as assessed by clinical indicators; (2) Incidence of clinical major adverse cardiovascular and cerebrovascular events (MACCE) within 30 days after thrombolysis; (3) Incidence of hemorrhagic events.

药物成份或治疗方案详述:

Prouk由411个氨基酸组成的单链蛋白质分子,含有12对二硫键,属非糖基化蛋白质,分子量为46393.65 Da,其国际通用名为Saruplase,通过激活与纤维蛋白Y/E片段结合的纤溶酶原,来溶解病理性血栓,其在血浆中是惰性的,通过转化成双链尿激酶,催化活力可以提高250-500倍。Prouk是一个相对比较特殊的蛋白水解酶原,不同于阿替普酶与血纤维蛋白的结合,Prouk并不与血纤维蛋白直接结合,而是通过激活与血纤维蛋白Y/E片段结合的纤溶酶原来实现,其不但是血纤维蛋白而且是栓塞血栓的专一性,更大程度避免出血等不良反应,这对于溶栓药物的临床使用相当重要。 

Description for medicine or protocol of treatment in detail:

Prouk is a single-chain protein molecule composed of 411 amino acids, containing 12 pairs of disulfide bonds. As a non-glycosylated protein with a molecular weight of 46393.65 Daltons (Da), its International Nonproprietary Name (INN) is Saruplase. Prouk exerts its thrombolytic effect by activating plasminogen bound to the fibrin Y/E fragments, thereby dissolving pathological thrombi. It is inert in plasma; upon conversion to two-chain urokinase, its catalytic activity increases by 250 to 500 folds. Prouk is a relatively unique proteolytic zymogen. Unlike alteplase, which binds directly to fibrin, Prouk does not exhibit such direct binding. Instead, it exerts its therapeutic effect through the activation of fibrin Y/E fragment-bound plasminogen. This mechanism endows Prouk with high specificity not only for fibrin but also for occlusive thrombi, which minimizes the risk of adverse reactions such as bleeding. This characteristic is of great significance for the clinical application of thrombolytic agents.

随机方法(请说明由何人用什么方法产生随机序列):

本研究采用区组随机化方法,通过中央随机系统(IWRS/IRT)对受试者进行随机分组管理和试验药品管理。各中心采用竞争入组的方式将筛选合格的受试者按1:1的比例随机分配至试验药物注射用重组人尿激酶原组和阳性对照药物阿替普酶组。

Randomization Procedure (please state who generates the random number sequence and by what method):

This study adopts a block randomization method, and conducts random group assignment and investigational drug management for subjects via the Interactive Web Response System/Interactive Response Technology (IWRS/IRT). All participating centers enroll eligible screened subjects through a competitive enrollment approach, with such subjects randomly allocated in a 1:1 ratio to the Recombinant Human Prourokinase for Injection group (investigational drug) and the Alteplase group (positive control drug).

是否公开试验完成后的统计结果:

Calculated Results after the Study Completed public access:

不公开/Private

盲法:

因试验药物和对照药物使用方法有明显差异,研究采用随机、单盲、非劣效设计的试验方法。同时,主要终点为客观指标,随机分组信息对影像评审委员会(IRC)保持盲态,评估者在盲态下审核,可以有效控制单盲设计相关结局评估的偏倚。

Blinding:

Given the significant differences in the administration methods of the investigational drug and the control drug, this study adopts a randomized, single-blind, non-inferiority trial design. In addition, the primary endpoint is an objective measure, and the randomization assignment information remains masked to the Independent Review Committee (IRC). The reviewers conduct evaluations in a masked manner, which can effectively control the bias associated with outcome assessment under the single-blind design.
