Clinical Trial 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).


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.

Outcome

Type Measure Description Time frame Safety issue
Primary Evaluation of platelet response(continuous response rate) 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. up to 1 year per subject
Secondary therapy associated adverse events The number and frequency of therapy associated adverse events up to 1 year per subject
