入选标准

  • Informed consent obtained before any trial-related procedures.
  • 2.Age >18 years.
  • 3.Confirmed presence of thrombocytopenia with platelet count < 30,000/mm3 at the pre-dose visit. In each cohort< 200 µg/kg a maximum of 3 subjects will be included with platelet counts < 10,000/mm3, and in cohorts > 200 µg/kg a maximum of 1 subject with platelet counts < 10,000/mm3 will be included in order to limit variability. Two individual pre-dose platelet counts taken on the dosing day within > 1 hour interval between each other and both being < 30,000/mm3 will be used to confirm thrombocytopenia.
  • 4.History of isolated ITP (thrombocytopenia with no known aetiology, blood smear showing normal appearing platelets or, if performed, a bone marrow showing adequate thrombopoïesis and normal erythroid and myeloid morphology).
  • 5.RhD-positive serology.
  • 6.Previous treatment and response to first line therapy for ITP (corticosteroids, anti-D or IVIg), with response being defined as an increase in platelet count to =30,000/mm3.
  • 7.If female and of child-bearing potential, subject has a negative pregnancy test at screening.
  • 8.If subject is a female of child-bearing potential, subject agrees to use a medically accepted form of contraception from the time of enrolment (at screening) to completion of all follow-up trial visits.
  • Are the trial subjects under 18? no
  • Number of subjects for this age range:
  • F.1.2 Adults (18-64 years) yes
  • 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

排除标准

  • Known clinical picture suggestive of other causes of thrombocytopenia, especially systemic lupus erythematosus, antiphospholipid syndrome, Evans syndrome, immunodeficiency states, lymphoproliferative disorders, liver disease, ingestion of drugs such as quinidine/quinine, heparin and sulfonamides and hereditary thrombocytopenia confirmed by relevant laboratory findings.
  • 2.Suspected infection with HIV, hepatitis C, H. pylori unless corresponding laboratory test are negative.
  • 3.Clinical splenomegaly (the spleen should not be palpable at more than 1 finger breadth below the costal margin).
  • 4.History of abnormal bone marrow examination (except ITP-typical megacaryocytosis).
  • 5.At pre-dose visit: an ongoing haemorrhage corresponding to a grade 3 or 4 on the WHO bleeding scale.
  • 6.History of anaphylaxis or hypersensitivity reactions following anti-D treatment.
  • 7.Current immune haemolytic anaemia.
  • 8.Underlying haemolytic condition (e.g. reticulocyte count > 3%).
  • 9.Planned surgery during the 15 days post dosing.
  • 10.Haemoglobin pre-dose value lower than 2.0 g/dL below the lower limit of the laboratory normal range for gender and age.
  • 11.History of splenectomy.
  • 12.Known current malignancy (except basal cell carcinoma).
  • 13.Received other investigational agent within 3 months prior to enrolment.
  • 14.Positive DAT (direct Coombs-test) at screening unless subject has received treatment with IVIg or anti-D products within 3 months prior to screening with prior negative DAT.
  • 15.Known non-responders to most recent anti-D treatment (despite any initial response to treatment).
  • 16.Any other current treatment for ITP except corticosteroids (Prednisone or Dexamethasone) at doses equivalent to =30 mg prednisone/day if the daily dose has been constant for 2 weeks or more before trial drug administration.
  • 17.Therapy with IVIg within 2 weeks prior to enrollment or with anti-D or any other treatment of ITP within 4 weeks prior to enrolment.
  • 18.Therapy with tranexamic acid, alkylating agents or any anti-CD20 antibodies within 8 weeks prior to enrolment
  • 19.Any antithrombotic treatment (except acetyl salicylic acid at doses up to 150 mg daily) within 7 days prior to pre-dosing visit or planned during the trial.
  • 20.PT/INR and aPTT out of normal range at the pre-dose visit.
  • 21.History of venous or arterial thrombosis or know thrombophilia.
  • 22.Diseases other than ITP that may influence the result of the trial as judged by the Investigator.
  • 23.Creatinine 25% or more above normal range value, alanine aminotransferase (ALT) and alkaline phosphatase (ALP) 100% above normal range value, and albumin 25% or more below normal range value (according to the local laboratory) at pre-dose visit.
  • 24.Current or planned treatment with erythropoietin.
  • 25.Subject is pregnant, breast feeding or intends to become pregnant.
  • 26.Previous dosing with Sym001 in this trial.
