This is a multicenter, randomized, open-label, assessor-blind, event-driven, non-inferiority program for efficacy with a study treatment duration of 3, 6 or 12 months in patients with confirmed acute symptomatic DVT without symptomatic PE (Einstein-DVT).
Within the US 'Johnson \& Johnson Pharmaceutical Research \& Development, L.L.C.' is sponsor. The treatment period was followed by an observational period of 30 days starting the day after the last intake of study medication, regardless of the actual duration of study drug administration. Participants who did not complete the treatment period also entered the observational period. It was also possible that participants did not enter the observational period, e.g. due to withdrawal of consent or termination of study participation. Participants who were transferring from study 11702 DVT (NCT00440193) to the extension study 11899 (NCT00439725) did not enter the observational period.

During the first 3 weeks patients will receive 15 mg rivaroxaban twice-daily. Thereafter, patients will receive rivaroxaban 20 mg once-daily. Rivaroxaban will be administered orally and should be taken with food.
Enoxaparin 1.0 mg/kg twice daily with a minimal duration of 5 days. This 5 days treatment could include the period up to 36 h before randomization if enoxaparin twice-daily was used. VKA should be started as soon as possible but not later than 48 hours after randomization.
Percentage of Participants With Symptomatic Recurrent Venous Thromboembolism [VTE] (i.e. the Composite of Recurrent Deep Vein Thrombosis [DVT] or Fatal or Non-fatal Pulmonary Embolism [PE]) Until the Intended End of Study Treatment
All events were adjudicated and confirmed by a central independent adjudication committee blinded to treatment. Events were assessed based on either compression ultrasound (for DVT), venography (for DVT), spiral computed tomography (CT) scanning (for PE), pulmonary angiography (for PE), ventilation/perfusion lung scan (for PE), lung scintigraphy (for PE), autopsy (for fatal PE) or unexplained death for which DVT/PE could not be ruled out (for fatal PE), and/or case summaries.
Time frame: 3-, 6- or 12-month study treatment period
Percentage of Participants With the Composite Variable Comprising Recurrent DVT, Non-fatal PE and All Cause Mortality Until the Intended End of Study Treatment
All events were adjudicated and confirmed by a central independent adjudication committee blinded to treatment. Events were assessed based on either compression ultrasound (for DVT), venography (for DVT), spiral computed tomography (CT) scanning (for PE), pulmonary angiography (for PE), ventilation/perfusion lung scan (for PE), lung scintigraphy (for PE), autopsy (for deaths), results/films/images of confirmatory testing, and/or case summaries.
Time frame: 3-, 6- or 12-month study treatment period
Percentage of Participants With an Event for Net Clinical Benefit 1 Until the Intended End of Study Treatment
Net clinical benefit 1: composite of recurrent DVT or non-fatal or fatal PE, and major bleeding. Major bleeding was overt bleeding associated with 2 g/dL or greater fall in hemoglobin, leading to a transfusion of ≥2 units, occurring in a critical site or contributing to death. Net clinical benefit was considered greater in those participants with fewer composite events. All events were adjudicated and confirmed by a central independent adjudication committee blinded to treatment, based on either compression ultrasound, venography, spiral computed tomography scanning, pulmonary angiography, ventilation/perfusion lung scan, lung scintigraphy, autopsy or unexplained death for which DVT/PE could not be ruled out, results/films/images of confirmatory testing, and/or case summaries.

Time frame: 3-, 6- or 12-month study treatment period
Percentage of Participants With Recurrent DVT Until the Intended End of Study Treatment
All events were adjudicated and confirmed by a central independent adjudication committee blinded to treatment. Events were assessed based on either compression ultrasound, venography, results/films/images of confirmatory testing, and/or case summaries.
Time frame: 3-, 6- or 12-month study treatment period
Percentage of Participants With Clinically Relevant Bleeding, Treatment-emergent (Time Window: Until 2 Days After Last Dose)
All events were adjudicated and confirmed by a central independent adjudication committee blinded to treatment. Clinically relevant bleeding included major bleeding (overt bleeding associated with 2 g/dL or greater fall in hemoglobin, leading to a transfusion of 2 or more units of packed red blood cells or whole blood, occurring in a critical site or contributing to death) and non-major bleeding associated with medical intervention, unscheduled physician contact, (temporary) cessation of study treatment, discomfort for the participants such as pain, or impairment of activities of daily life.
Time frame: 3-, 6- or 12-month study treatment period
Percentage of Participants With All Deaths
All events were adjudicated and confirmed by a central independent adjudication committee blinded to treatment. Events were assessed based on either autopsy, results/films/images of confirmatory testing, and/or case summaries.
Time frame: 3-, 6- or 12-month study treatment period
Percentage of Participants With Other Vascular Events, On-treatment (Time Window: Until 1 Day After Last Dose)
All pre-defined vascular events (ST segment elevation myocardial infarction, non ST segment elevation myocardial infarction, unstable angina, ischemic stroke, transient ischemic attack, non-central nervous system systemic embolism or vascular death) were adjudicated and confirmed by a central independent adjudication committee blinded to treatment. Events were assessed based results/films/images of confirmatory testing, and/or case summaries.
Time frame: 3-, 6- or 12-month study treatment period
