NCT00311090

Brief Summary

The three purposes of this study are the following:

  • To compare during a 6-month treatment the safety and effectiveness of idrabiotaparinux (SSR126517) with that of idraparinux (SR34006), taking into account new events of deep venous thrombosis (DVT) and pulmonary embolism (PE), and bleeding risk;
  • To compare the activities of idrabiotaparinux and idraparinux directly in blood during and after a 6-month treatment;
  • To check the ability of avidin (SSR29261) to reverse the blood thinning activity of idrabiotaparinux at the end of a 6-month treatment period.

Outcome Measures

Primary Outcomes (2)

  • Bioequipotency sub-study: idrabiotaparinux/idraparinux ratio for pharmacodynamic exposure parameters

    Day 183

  • Avidin neutralizing effect substudy: decrease in anti-Xa activity between the start and end of the avidin infusion

    Day 183 to Day 188

Secondary Outcomes (3)

  • Pharmacokinetic profile: idrabiotaparinux and idraparinux plasma concentrations

    Days 15, 36, 57, 92 and 183

  • Safety: number of participants with clinically relevant bleedings and number of deaths as confirmed by a Central Independent Adjudication Committee (CIAC)

    First 6 months

  • Efficacy: number of participants with symptomatic recurrent venous thromboembolism as confirmed by the CIAC

    First 6 months

Study Arms (2)

Idrabiotaparinux

EXPERIMENTAL

Idrabiotaparinux sodium , 3.0 mg, once-weekly for 6 months. In avidin sub-study, participants receive on Day 183, avidin 100 mg or placebo (for avidin) (4 hours after Idrabiotaparinux administration)

Drug: Idrabiotaparinux sodiumDrug: AvidinDrug: Placebo (for Avidin)

Idraparinux

ACTIVE COMPARATOR

Idraparinux sodium, 2.5 mg, once-weekly for 6 months In avidin sub-study, participants receive on Day 183, placebo (for avidin) (4 hours after Idrabiotaparinux administration)

Drug: Idraparinux sodiumDrug: Placebo (for Avidin)
