Brief Summary:
The project was undertaking by Qilu Hospital of Shandong University in China. In order to compare the efficacy, safety and response duration of different dose of rituximab in patients primary immune thrombocytopenia(pITP).

Condition or disease Intervention/treatment Phase
Purpura, Thrombocytopenic, Idiopathic Immune Thrombocytopenia Drug: Rituximab Phase 4

Detailed Description:
62 patients with pITP who had failed to respond to glucocorticosteroids were randomly divided into 2 groups: group A(n = 32) and group B(n = 30). In group A, Rituximab was given with a fixed dose of 100 mg administered as an intravenous infusion weekly (on day 1, 8, 15 and 22). In group B, Rituximab was given with a single dose of 375mg/m2. The clinical effect, onset time, duration of efficacy and adverse reactions were observed to compare the efficacy and safety of two different plans.

Primary Outcome Measures :
  1. Evaluation of platelet response(continuous response rate) [ Time Frame: up to 1 year per subject ]
    Complete Response:a sustained (≥ 3 months) platelet count≥100×10^9/L;response: a sustained (≥ 3 months) platelet count ≥ 30×10^9/L without recurrence of thrombocytopenia;No response (NR): 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.

Secondary Outcome Measures :
  1. therapy associated adverse events [ Time Frame: up to 1 year per subject ]
    The number and frequency of therapy associated adverse events
