Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Treatment: Drugs - Idrabiotaparinux sodium
Treatment: Drugs - Warfarin
Treatment: Drugs - Placebo (for idrabiotaparinux sodium)
Treatment: Drugs - Avidin
Treatment: Drugs - Placebo (for warfarin)
Treatment: Drugs - Enoxaparin

Experimental: Idrabiotaparinux - Idrabiotaparinux sodium, 3.0 mg, once-weekly for 3 or 6 months depending on the stratum, after enoxaparin, 1.0 mg/kg, every 12 hours for at least 5 days.

Summary
Brief summary
Objectives are to evaluate whether idrabiotaparinux sodium (SSR126517E) is as least as effective as a standard warfarin treatment to prevent recurrence of venous thromboembolic events (VTE) in patients with symptomatic pulmonary embolism (PE) with or without symptomatic deep venous thrombosis (DVT) and to assess its safety (bleedings) versus warfarin.
