Key inclusion & exclusion criteria
Inclusion criteria:
1) Males and females aged between 18 and 70 years.
2) Confirmed diagnosis of chronic ITP of at least 6 months duration.
3) Platelet count <=20x10^9/L at enrollment.
4) Absence of other conditions that, in the opinion of the investigator, could cause thrombocytopenia.
5) If subjects are currently being treated with corticosteroids the treatment regimen/dose must have been stable (for a minimum of 2 weeks before Day 1 infusion). However, subjects must remain on a stable treatment regimen. If there is any intent to alter the corticosteroid treatment regimen (e.g., tapering of corticosteroids) before Day 10, subjects may not be included in the study.
6) If subjects are currently being treated with cyclophosphamide, azathioprine or attenuated androgens, the treatment regimen and dose must have been stable for a minimum of 2 months before infusion on Day 1. However, if there is any intent to alter the treatment regimen before Day 10, subjects may not be included in the study.
7) Splenectomized subjects and both Rh(D)+ and Rh(D)- subjects may be included.
