简要总结
NewGam is a newly developed human normal immunoglobulin solution for intravenous administration (IGIV). This study will evaluate the safety and efficacy of NewGam 10% in patients with primary immune thrombocytopenia.
详细描述
The primary objective of the study is to assess the efficacy of NewGam in correcting the platelet count. The secondary objective of the study is to evaluate the safety of NewGam. Safety will be assessed by monitoring vital signs, physical examination, evaluation of adverse events (AE) and laboratory parameters, and viral safety testing.

入选标准
- •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.

排除标准
- •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
- •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
- •Unresponsive to previous treatment with IGIV or anti-D immunoglobulin.
