Description
Inclusion Criteria:
- Age of ≥ 18 and ≤ 65 years.
- Confirmed diagnosis of chronic primary immune thrombocytopenia (ITP) (diagnosed with a threshold platelet count < 100x10^9/L) of at least 12 months duration.
- Platelet count of no more than 20x10^9/L with or without bleeding manifestations.
- Freely given written informed consent from patient.
- Women of childbearing potential must have a negative result on a pregnancy test (human chorionic gonadotropin [HCG]-based assay) and need to practice contraception using a method of proven reliability for the duration of the study.
Exclusion Criteria:
- Thrombocytopenia secondary to other diseases (such as acquired immunodeficiency syndrome [AIDS] or systemic lupus erythematosus [SLE]), or drug-related thrombocytopenia.
Administration of intravenous immunoglobulin (IGIV), anti-D immunoglobulin or thrombopoietin receptor agonists, or other platelet enhancing drugs (including immunosuppressive or other immunomodulatory drugs) within 3 weeks before enrollment, except for:
- Long-term corticosteroid therapy when the dose has been stable during the preceding 3 weeks and no dosage change is planned until study Day 22.
- Long-term azathioprine, cyclophosphamide, or attenuated androgen therapy when the dose has been stable during the preceding 3 months and no dosage change is planned until study Day 22.
- Unresponsive to previous treatment with IGIV or anti-D immunoglobulin.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Percentage of Responders
Time Frame: Day 1 to Day 8
|
A responder is a study participant with an increase in platelets to ≥ 50x10^9/L within 7 days after the first infusion, ie, by study Day 8.
|
Day 1 to Day 8
|

Measure Description |
Time Frame |
|---|---|---|
|
Percentage of Alternative Responders
Time Frame: Day 1 to Day 22
|
An alternative responder is a study participant with an increase in platelets to ≥ 30x10^9/L and to at least double the baseline platelet count, confirmed on at least 2 occasions at least 7 days apart, and absence of bleeding.
|
Day 1 to Day 22
|
|
Percentage of Complete Responders
Time Frame: Day 1 to Day 22
|
A complete responder is a study participant with an increase in platelets to ≥ 100x10^9/L, confirmed on at least 2 occasions at least 7 days apart, and absence of bleeding.
|
Day 1 to Day 22
|
|
Percentage of Alternative Responders Who Lost the Response
Time Frame: Day 1 to Day 22
|
An alternative responder who lost the response is a study participant who met the criterion for an alternative response but who then deteriorated, ie, their platelet count decreased to < 30x10^9/L, their platelet count decreased to less than double the baseline count, or bleeding occurred.
|
Day 1 to Day 22
|
|
Percentage of Complete Responders Who Lost the Response
Time Frame: Day 1 to Day 22
|
A complete responder who lost the response is a study participant who met the criterion for a complete response but who then deteriorated, ie, their platelet count decreased to < 100x10^9/L or bleeding occurred.
|
Day 1 to Day 22
|
|
Time to a Response
Time Frame: Day 1 to Day 8
|
A study participant had a response if their platelets increased to ≥ 50x10^9/L within 7 days after the first infusion, ie, by study Day 8.
|
Day 1 to Day 8
|
|
Time to an Alternative Response
Time Frame: Day 1 to Day 22
|
A study participant had a response if their platelets increased to ≥ 30x10^9/L and to at least double the baseline platelet count, confirmed on at least 2 occasions at least 7 days apart, and absence of bleeding.
|
Day 1 to Day 22
|
|
Time to a Complete Response
Time Frame: Day 1 to Day 22
|
A study participant had a complete response if their platelets increased to ≥ 100x10^9/L, confirmed on at least 2 occasions at least 7 days apart, and absence of bleeding.
|
Day 1 to Day 22
|
|
Duration of a Response
Time Frame: Day 1 to Day 22
|
The duration of a response was defined as the time from when a response was achieved until the platelet count fell below 50x10^9/L.
|
Day 1 to Day 22
|
|
Duration of an Alternative Response
Time Frame: Day 1 to Day 22
|
The duration of an alternative response was defined as the time from when an alternative response was achieved until the platelet count fell below 50x10^9/L.
|
Day 1 to Day 22
|
|
Duration of a Complete Response
Time Frame: Day 1 to Day 22
|
The duration of a complete response was defined as the time from when a complete response was achieved until the platelet count fell below 50x10^9/L.
|
Day 1 to Day 22
|
|
Platelet Count by Visit
Time Frame: Day 1 to Day 22
|
The platelet count at each study visit are presented.
|
Day 1 to Day 22
|
|
Maximum Platelet Count
Time Frame: Day 1 to Day 22
|
The maximum platelet count achieved during the study is presented.
|
Day 1 to Day 22
|
|

|
Day 1 to Day 22
|
|
