Phase 3
Completed
Conditions
Superficial Vein Thrombosis
Interventions
Registration Number
NCT01499953
Lead Sponsor
GWT-TUD GmbH
Brief Summary

The purpose of this study is to evaluate the efficacy and safety of rivaroxaban versus fondaparinux in the treatment of superficial vein thrombosis (SVT).

Detailed Description

Evaluation of efficacy and safety of 45 days of rivaroxaban 10 mg vs. fondaparinux 2.5 mg in the treatment of superficial vein thrombosis of risk patients for major VTE complications to prove non-inferiority of oral rivaroxaban treatment

Primary Outcome Measures
NameTimeMethod
Rate of Objectively Confirmed VTE Complications45 +/- 5 days

The primary efficacy outcome was the composite of death from any cause, symptomatic pulmonary embolism (confirmed by ventilation-perfusion scanning, helical computed tomography, pulmonary angiography, or autopsy), symptomatic deep vein thrombosis (confirmed by ultrasonography or venography), or symptomatic extension towards the saphenofemoral junction or symptomatic recurrence of superficial vein thrombosis (confirmed by ultrasonography) up to day 45.

Secondary Outcome Measures
NameTimeMethod
Rates of Surgery for SVT90 +/-10 days
Rate of Major VTE90 +/-10 days

composite of:

* symptomatic pulmonary embolism

* symptomatic proximal DVT

* VTE-related death

Composite Primary Efficacy Outcome90 +/- 10 days

For this, secondary efficacy outcomes were the composite primary efficacy outcome up to Day 90 and the following outcomes up to Day 45 and Day 90: each component of the primary efficacy outcome, the rate of major VTE (composite of symptomatic pulmonary embolism or symptomatic proximal DVT or VTE-related death) and the rates of surgery for SVT.
