简要总结
The purpose of this study is to evaluate the efficacy and safety of rivaroxaban compared with placebo in the prevention of symptomatic venous thromboembolism (VTE) events and VTE-related death post-hospital discharge in high-risk, medically ill patients.
详细描述
This is a randomized (the study medication is assigned by chance), double-blind (neither physician nor participant knows the identity of the assigned treatment), placebo (an inactive substance that is compared with a drug to test whether the drug has a real effect)-controlled, event-driven, multicenter study in patients who are hospitalized for a specific acute medical illness and have other risk factors for venous thromboembolism (VTE). The study is designed to evaluate rivaroxaban in the prevention of symptomatic VTE events and VTE-related deaths for a period of 45 days post-hospital discharge. The study will consist of a screening phase, a 45-day double-blind treatment phase, and a 30-day follow-up phase. Study drug will start at randomization (Day 1), and will continue until Day 45 (inclusive). A total of approximately 12000 patients will be randomly assigned to either rivaroxaban or placebo in a 1:1 ratio. The total duration for a patient who completes the study after randomization is expected to be 75 days.

研究组 & 干预措施
Rivaroxaban
Each patient will receive either 10 mg or 7.5 mg rivaroxaban tablet once daily orally (by mouth) for 45 days. The dosing will depend on a creatinine clearance at screening.

结局指标
主要结局
Event Rate Based on Time From Randomization to the First Occurrence of Major Bleeding Adjudicated by CEC
时间窗: From randomization to 2 days after the last dose (Day 45)
A major bleeding event was defined using validated International Society on Thrombosis and Haemostasis (ISTH) bleeding criteria. A major bleeding event was defined as overt bleeding that was associated with a fall in hemoglobin of 2 gram per deciliter (g/dL) or more, or a transfusion of 2 or more units of packed red blood cells or whole blood, or a critical site defined as intracranial, intraspinal, intraocular, pericardial, intra-articular, intramuscular with compartment syndrome, retroperitoneal, or a fatal outcome. Event rate was defined as number of events per 100 participants in 45 days of follow up. Participants who did not have events were censored on the minimum of last visit before or on death, or last dose + 2 days.
Time From Randomization to First Occurrence of Composite of All Symptomatic Venous Thromboembolism (VTE) and VTE Related Death Adjudicated by Clinical Event Committee (CEC)
时间窗: Up to Day 45
Symptomatic VTE included lower extremity deep vein thrombosis (DVT) and non-fatal pulmonary embolism (PE). Event rate was defined as number of events per 100 participants in 45 days of follow up. Participants who did not have events were censored on the minimum of last visit before or on death, or Day 45.
