Clinical Trial 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).

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

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Major Bleeding (Main Safety Outcome)	associated with a fall of hemoglobin of 2 g/l or more, or; leading to a transfusion of 2 or more units of packed red blood cells or whole blood, or; occurring into a critical site such as intracranial, intraspinal, intraocular, pericardial, intraarticular, intramuscular with compartment syndrome, retroperitoneal, or; fatal bleeding.	45 +/- 5 days
Other	Clinically Relevant Non-major, Minor and Total (Any) Bleeding	Clinically relevant, non-major bleeding is defined as any overt bleeding and; associated with a medical intervention, or; unscheduled contact with the physician (presence or telephone contact); temporary or complete cessation of study drug; associated with any relevant discomfort to the patient (pain, impairment of activities of daily life)	45 +/- 5 days
Primary	Rate of Objectively Confirmed VTE Complications	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.	45 +/- 5 days
Secondary	Composite Primary Efficacy Outcome	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.	90 +/- 10 days
Secondary	Rate of Major VTE	composite of: symptomatic pulmonary embolism; symptomatic proximal DVT; VTE-related death	90 +/-10 days
Secondary	Rates of Surgery for SVT		90 +/-10 days
