NCT01629381

Brief Summary

Study Objective: To assess the value of Rivaroxaban for the prevention of venous thromboembolism (VTE) after knee arthroscopy (KA) taking the placebo as standard of reference. Study Population: Patients undergoing therapeutic KA at the study Centers, irrespective of the type and duration of the procedure, will be eligible for the study. Study Design: Multicenter, randomized, double blind superiority, phase II trial comparing two arms:

  • (R-7d) Rivaroxaban (10 mg od os) for 7 days
  • (PL-7d) Placebo for 7 days. Follow-up: 3-month period after the randomization Standard of Reference:Placebo will be the standard of reference in accordance to international guidelines Study length May 2012-December 2012 Total patients number: 500 patients Primary Efficacy End-Point: Occurrence in the 3-month period after the randomization of at least one of the following events, objectively proven (by means of CCDU; multi-slice chest TC-angio; autopsy, if necessary, or clinical ground):
  • All-cause mortality
  • Symptomatic VTE
  • Asymptomatic proximal DVT Secondary Efficacy End-point:
  • Combined incidence of all DVT plus symptomatic PE Primary Safety End-point: Incidence of major bleedings. Secondary Safety End-point: Overall incidence of bleeding

Outcome Measures

Primary Outcomes (2)

  • Incidence of Symptomatic Venous Thromboembolism Plus Asymptomatic Proximal Vein Thrombosis and All-cause Mortality

    During the scheduled visit in case of suspected DVT a bilateral whole-leg colour-coded Doppler ultrasonography (CCDU) is scheduled for all patients at 7 (+1) days of follow-up; additionally, CCDU will be performed if the patients develop symptoms or signs suggestive of venous thromboembolism earlier; in case of suspected PE a multi-slice chest TC-angio is arranged; in case of death for all cause autoptic findings are requested or, if necessary, clinical ground is considered. A follow-up visit is planned 3-month period after the randomization.

    3-month period

  • Major Bleedings

    Major bleeding include: clinically overt haemorrhage associated with haemoglobin drop of at least 2 g/L or requiring the transfusion of two or more units of packed red-blood cells; retroperitoneal or intracranial events; bleeding requiring re-intervention; and hemarthrosis with a joint drainage of more than 450 millilitres of blood.
