Venous Thrombosis
Conditions
Brief summary
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).
Detailed description
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.
Interventions
DRUGRivaroxaban (Xarelto, BAY59-7939)
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.
DRUGEnoxaparin followed by VKA
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.

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
Population: The intention-to-treat (ITT) population consisted of all randomized participants with valid informed consent. Participants were analyzed according to the treatment assigned at randomization.

Comparison: The rivaroxaban to comparator hazard ratio was computed with a 95% CI (confidence interval) (two-sided testing). Based on this model, rivaroxaban would be considered at least as effective as the comparator if the upper limit of the CI was less than 2.0.p-value: <0.000195% CI: [0.44, 1.04]Regression, Cox

| Arm | Measure | Value (NUMBER) |
|---|---|---|
| Rivaroxaban (Xarelto, BAY59-7939) | Percentage of Participants With the Composite Variable Comprising Recurrent DVT, Non-fatal PE and All Cause Mortality During Observational Period | 2.2 Percentage of participants |
| Enoxaparin/VKA | Percentage of Participants With the Composite Variable Comprising Recurrent DVT, Non-fatal PE and All Cause Mortality During Observational Period | 1.8 Percentage of participants |
Other Pre-specified
Percentage of Participants With the Individual Components of Efficacy Outcomes During Observational Period
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. 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.

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
Population: The intention-to-treat (ITT) population consisted of all randomized participants with valid informed consent. Participants were analyzed according to the treatment assigned at randomization.
