利伐沙班与阿哌沙班治疗急性静脉血栓栓塞症的出血风险比较 (COBRRA)
研究概览
详细说明
VTE 是心血管疾病导致死亡的第三大原因。 急性 VTE 的标准治疗使用肠外低分子肝素 (LMWH) 和口服维生素 K 拮抗剂 (VKA) 联合治疗 3 个月,并具有显着的出血风险。 据报道,在初始治疗期间,主要和/或临床相关的非主要出血 (CRNMB) 事件发生率在 8.1-9.7% 之间。 由于皮下注射、药物相互作用和实验室监测,这种治疗很麻烦。 直接口服抗凝剂 (DOAC) 使用更简单,不需要实验室监测。
利伐沙班和阿哌沙班是两种针对 Xa 因子的 DOAC。 与标准治疗相比,每种 DOAC 都被单独证明是有效和安全的。 比较研究之间的出血率将有利于使用阿哌沙班而不是利伐沙班;然而,试验的局限性和这两种药物之间缺乏直接比较使得无法得出确切的结论。 这代表了临床实践中的两难境地,因为缺乏令人信服的安全性差异导致真正不确定哪种 DOAC 具有最佳风险收益比。
为了解决这些局限性,需要进行头对头随机对照试验 (RCT) 来确定安全性(即 在急性 VTE 治疗的前 3 个月内,每日两次阿哌沙班优于每日一次利伐沙班的出血风险)。 资格标准将不如 COBRRA 试点研究严格,并反映真实世界的患者。 还将进行每日两次阿哌沙班与每日一次利伐沙班相比的成本效益分析。

The Rate of Adjudicated Clinically Relevant Bleeding (CRB) Events
大体时间:For the duration of the study: 3 months
|
CRB events are defined as the composite of major bleeding (MB) events and clinically relevant non-major bleeding (CRNMB) events.

Number of Participants With Adjudicated Major Bleeding Events
大体时间:For the duration of the study: 3 months
|
Major bleeding will be defined as fatal bleeding, and/or, Symptomatic bleeding in a critical area or organ, such as intracranial, intraspinal, intraocular, retroperitoneal, intra-articular or pericardial, or intramuscular with compartment syndrome, and/or bleeding causing a fall in hemoglobin of ≥20 g/L, or leading to transfusion of ≥2 units of whole blood or red cells.

For the duration of the study: 3 months
|
|
Number of Participants With Adjudicated Clinically Relevant Non-Major Bleeding Events
大体时间:For the duration of the study: 3 months
|
Clinically relevant non-major bleeding will be defined as any sign or symptom of hemorrhage (e.g., more bleeding than would be expected for a clinical circumstance, including bleeding found by imaging alone) that does not fit the criteria for the International Society on Thrombosis and Haemostasis (ISTH) definition of major bleeding but does meet at least one of the following criteria:

For the duration of the study: 3 months
|
|
Number of Participants With Adjudicated Recurrent Venous Thromboembolism (VTE) Events
大体时间:For the duration of the study: 3 months
|
Recurrent VTE will be confirmed with investigational reports including clinic notes, D-dimer results and imaging as per standard of care.
Recurrent Deep Vein Thrombosis (DVT) will be confirmed by compression ultrasound revealing a new (compared to baseline/index ultrasound) area of non-compressibility in the popliteal vein or more proximal vein, or venography demonstrating a constant intraluminal filling defect in the popliteal vein or more proximal veins.
Recurrent Pulmonary Embolism (PE) will be diagnosed if the Ventilation-Perfusion (VQ) scan is non-normal and a new unmatched segmental or greater perfusion defect is documented, or an intraluminal filling defect is seen on Computed Tomography Pulmonary Angiogram (CTPA) in a segmental or greater vessel that was previously free of thrombus, or pulmonary angiography demonstrating a constant intraluminal filling defect or a cutoff of a vessel >2.5 mm in diameter will be considered diagnostic for PE.
