Outcome Measures

Primary Outcomes (3)

  • Evaluation of platelet response (Complete Response)

    CR. A complete response (CR) was defined as a sustained (≥ 3 months) platelet count ≥ 100×10\^9/L without recurrence of thrombocytopenia

    The time frame is up to 3 months per subject

  • Evaluation of platelet response (R)

    R. A response (R) was defined as a sustained (≥ 3 months) platelet count ≥ 30×10\^9/L without recurrence of thrombocytopenia

    The time frame is up to 3 months per subject

  • Evaluation of platelet response (No Response)

    NR.No response (NR) was defined as platelet count \< 30 × 10\^9/L or a less than two fold increase in platelet count from baseline or the presence of bleeding. Platelet count must be measured on two occasions more than a day apart.

    The time frame is up to 3 months per subject

Secondary Outcomes (1)

  • The number and frequency of therapy associated adverse events

    up to 3 months per subject

Study Arms (1)

combination treatment

EXPERIMENTAL
Drug: rhTPO in combination with Rituximab

Interventions

Rituximab was given intravenously at a dose of 100 mg weekly for 4 consecutive weeks (Day 1, 8, 15, 22). Rh-TPO (TPIAOTM, a product of Sunshine Pharmaceutical Co Ltd, China, approved by China State Food and Drug Administration) was given subcutaneously at a dose of 1.0 μg/kg(300u/kg)for 14 days (Day 1-14).

Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Meet the diagnostic criteria for immune thrombocytopenia.
  • Untreated hospitalized patients, may be male or female, between the ages of 18 \~ 80 years.
  • To show a platelet count \<30×10\^9/L, and with bleeding manifestations.
  • Willing and able to sign written informed consent.

You may not qualify if:

  • Received chemotherapy or anticoagulants or other drugs affecting the platelet counts within 3 months before the screening visit.
  • Received second-line ITP-specific treatments (eg, cyclophosphamide, 6-mercaptopurine, vincristine, vinblastine, etc) within 3 months before the screening visit.
  • Received high-dose steroids or IVIG in the 3 weeks prior to the start of the study.
  • Current HIV infection or hepatitis B virus or hepatitis C virus infections.
  • Severe medical condition (lung, hepatic or renal disorder) other than chronic ITP. Unstable or uncontrolled disease or condition related to or impacting cardiac function (e.g., unstable angina, congestive heart failure, uncontrolled hypertension or cardiac arrhythmia)
  • Female patients who are nursing or pregnant, who may be pregnant, or who contemplate pregnancy during the study period.
  • Have a known diagnosis of other autoimmune diseases, established in the medical history and laboratory findings with positive results for the determination of antinuclear antibodies, anti-cardiolipin antibodies, lupus anticoagulant or direct Coombs test.
  • Patients who are deemed unsuitable for the study by the investigator.
