Conditions

Venous Thromboembolism

Brief summary

This is a multicenter, randomized, double-blind, placebo-controlled, event-driven, superiority study for efficacy. Patients with confirmed symptomatic DVT (deep vein thrombosis) or PE (pulmonary embolism) who completed 6 or 12 months of treatment with rivaroxaban or VKA (vitamin K antagonist) are eligible for this trial (Einstein-Extension study).

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.

Interventions

DRUGRivaroxaban (Xarelto, BAY59-7939)

Patients randomized to rivaroxaban will receive rivaroxaban 20 mg once-daily.

DRUGPlacebo

Patients allocated to placebo will receive a matching placebo tablet once daily.

Inclusion criteria

* Patients with confirmed symptomatic PE or DVT who have been treated for 6 or 12 months with VKA or rivaroxaban

Exclusion criteria

* Legal lower age limitations (country specific) * Indication for VKA other than DVT and/or PE * Patients in whom anticoagulant treatment for their index PE or DVT should be continued * Childbearing potential without proper contraceptive measures, pregnancy or breast feeding. Proper contraceptive measures are defined as a method of contraception with a failure rate \< 1 % during the course of the study (including the observational period). These methods of contraception according to the note for guidance on non-clinical safety studies for the conduct of human trials for pharmaceuticals (CPMP \[Committee for Proprietary Medicinal Products\]/ICH \[International Conference on Harmonization\]/286/95, modification) include consistent and correct use of hormone containing implants and injectables, combined oral contraceptives, hormone containing intrauterine devices, surgical sterilization, sexual abstinence and vasectomy

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. For definition of DVT/PE, kindly refer to the link in the Protocol section.

Events were adjudicated/confirmed by a central independent adjudication committee blinded to treatment, based on either compression ultrasound, venography, spiral CT 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 or more units, occurring in a critical site or contributing to death.

Time frame: 30 days observational period after last intake of study medication

Population: Intention-to-treat (ITT) population entering observational period. Participants were analyzed according to the treatment assigned at randomization.
