  • Refractory patients who have either not responded to one or more prior therapies, or have relapsed within 3 months prior therapy. Previous therapies include corticosteroids, IVIG, anti-D immunoglobulin, azathioprine, danazol, cyclophosphamide, immunomodulators and/or splenectomy. Previous therapies with immunoglobulins, immunomodulators and cyclophosphamide must have been completed at least two weeks prior to randomization.
  • Subjects with maintenance immunosuppressive therapy (corticosteroids, azathioprine, danazol, cyclosporine A, MMF) and inadequate increase of platelets (<30,000/mikroliter).
  • Subjects treated with maintenance immunosuppressive therapy (corticosteroids, danazol, cyclosporine A) must be receiving a dose that has been stable for at least 1 month.
  • Normal protrombin time (PTT) and activated partial thromboplastin time (aPTT).
  • A complete blood count, reticulocyte count, creatinine, ALT, AST, bilirubin within the reference range with the following exceptions:
  • Platelet count < 30.000/mikroliter
  • Hemoglobin: female and male >= 10.0 g/dL are eligible for inclusion.
  • ANC>=1500/mikroliter is required for inclusion; elevated WBC/ANC due to steroid treatment is acceptable.
  • Subject is practicing an acceptable method of contraception (documented in chart). Female subject or female partners of male subjects must either be on non-childbearing potential (hysterectomy, bilateral, oophrenectomy, bilateral tube ligation or post-menopausal >=1 year).
  • Complete abstinence of intercourse
  • Intrauterine device
  • Two forms of barriers contraception
  • Male partner is sterile and the one partner of the female. Contraception: if subject is male – partner is sterile, if female – subject sterile.

  • F.1.2.1 Number of subjects for this age range
  • F.1.3 Elderly (>=65 years) yes
  • F.1.3.1 Number of subjects for this age range

  • Subject has consumed aspirin, aspirin containing compounds, anti-coagulants or non-steroidal anti-inflammatories for > 3 consecutive days within 2 weeks during the study.
  • Any laboratory or clinical evidence for HIV, Hepatitis C, chronic Hepatitis B infection beta-chorionic gonatrotropin pregnancy test) at screening at pre-dose on Day 1.
  • History of alcohol/drug abuse or dependence within 12 months of the study.
  • Treatment with an investigational drug within 30 days or 5 half-lives preceding the first dose of study medication.
  • A complete blood count (CBC) and/or reticulocyte count outside the reference range , with the following exceptions:
  • Platelet count < 30.000/mikroliter is required for inclusion.
  • Haemoglobin: females and males >=10 g/dL are eligible for inclusion.
  • ANC>=1500/mikroliter (1.5 x 109/L) is eligible for inclusion.
  • History of platelet aggregation that prevents reliable measuring of platelet counts.
  • An laboratory or clinical evidence for HIV infection; an clinical history or laboratory evidence for hepatitis C infection; an clinical history or laboratory evidence for hepatitis B infection; or any evidence for active hepatitis at the time of subject screening; if the potential subject has no clinical history that would support HIV infection or hepatitis infection, no further laboratory screening is necessary; however standard medical practice would suggest evaluation of patients who have risk factors for these infections.
  • Persons who are detained officially or legally to an official institute
