NCT00567502

Brief Summary

This is an observational safety study being conducted in Europe comparing patients taking Xagrid to patients taking other cytoreductive treatments. The plan is to enrol at least 750 subjects taking Xagrid with up to 3000 subjects taking other cytoreductive therapies. The study will collect follow up data for 5 years for each patient enrolled that will focus on collecting data related to pre-defined events (PDEs) and Suspected Serious Adverse Reactions (SSARs).

Outcome Measures

Primary Outcomes (2)

  • Percentage of Participants With At Least One Pre-Defined Event (PDE), Deaths, Pregnancies

    Pre-defined events (PDEs) were evaluated whenever an event occurred and was defined by a panel of independent qualified physicians, blinded to cytoreductive therapy, validated all PDEs prior to analysis (Event Validation Panel). Non-PDE death only included deaths not recorded as outcome of another PDE.

    Up to 5 years

  • Number of Participants With Suspected Serious Adverse Reaction (SSAR) Events

    SSAR: serious adverse event (SAE) that was considered related to cytoreductive therapy. SAE: any untoward medical occurrence that at any dose resulted in death, life-threatening (at the time of the event), in-patient hospitalization/prolongation of existing hospitalization (elective hospitalizations/procedures for pre-existing conditions that had not worsened were excluded), resulted in persistent or significant disability/incapacity or congenital abnormality/birth defect. Relatedness (suspected/not suspected) to XAGRID or other cytoreductive theraphy was determined by the investigator. As for SSARs, it was important to consider whether the events were related to XAGRID or other cytoreductive therapy. A participant was included in Xagrid or other treatment group based on treatment exposure, participants received Xagrid + Other was counted both in Xagrid and other treatment group.

    Up to 5 years

Secondary Outcomes (4)

  • Event Rate of Thrombohaemorrhagic Events

    Up to 5 years

  • Platelet Count
