Study Overview
Status
Conditions
Intervention / Treatment
Detailed Description
To determine if IGIV3I Grifols 10% is a consistently effective treatment in patients diagnosed with immune thrombocytopenic purpura with respect to:
- Increase of platelet count ≥ 50x10^9/L (primary objective).
- Time taken for the platelet count to reach ≥ 50x10^9/L.
- The length of time the platelet count remains ≥ 50x10^9/L.
- The maximum platelet level.
- Regression of bleeding episodes during the first 10 or 14 days.
To determine if IGIV3I Grifols 10% is safe with respect to:
Nature, severity and frequency of adverse reactions during and after infusions by percentage of subjects and percentage of infusions.
