Brief summary
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.
Detailed description
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.
Interventions
Patients, randomly allocated to the rivaroxaban arm, with a creatinine clearance at screening greater than or equal to (\>=)50 mL/min will receive 10 mg rivaroxaban tablet with or without food.
Patients, randomly allocated to the rivaroxaban arm, with a creatinine clearance at screening from \>=30 to less than (\<)50 mL/min will receive 7.5 mg rivaroxaban tablet with or without food.
All patients, randomly allocated to the placebo arm, will receive one placebo tablet with or without food.

Event Rate Based on Time From Randomization to the First Occurrence of Major Bleeding Adjudicated by CEC
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 frame: From randomization to 2 days after the last dose (Day 45)
