Clinical Trial Summary

SLE associated immune thrombocytopenia (SLE-ITP) is one of the main clinical manifestations of SLE. Approximately 70% of SLE patients follow a relapsing-remitting course. Similarly, SLE-ITP often relapses during GCs tapering. At the same time, patients with SLE-ITP may suffer from thrombocytopenia and damage to vital organs when they relapse, seriously affecting their lives. Therefore, maintenance therapy after remission is an inevitable choice for SLE-ITP. The SLE guidelines recommend GCs and immunosuppressive agents(ISA) are first-line maintenance treatment in the treatment of SLE-ITP. GCs is indispensable in SLE treatment, but it is associated with a series of side effects, which are related to the dosage and duration of use. How to maintain remission with the most appropriate dose of GCs is a problem that needs to be considered in clinical practice. However, the existing guidelines lack detailed recommendations on the specific use of GCs in maintenance therapy for SLE-ITP, and there is also a lack of relevant clinical studies to guide. The GCs reduction regimen commonly used in maintenance therapy is a gradual reduction after 1 month of adequate GCs therapy, usually by 10% of the original dose every 2 weeks. However, the side effects of this reduction method are obvious, and whether the treatment can be maintained with less cumulative dose and maintenance duration of GCs is an urgent problem to be solved. Clinical observations show that in a small number of patients with relative contraindications to GCs, a more rapid taper can maintain an effective response. Currently, rapid dosing reduction is recommended in both Lupus nephritis(LN) and the ANCA-associated nephritis guidelines of ACR. However, SLE-ITP changes more rapidly than LN. Although similar maintenance responses have been observed in a few patients between rapid dosing reduction and conventional method, relevant clinical studies are lacking. It is necessary to explore the effectiveness of rapid GCs tapering method. Therefore, the investigators plan to conduct a single-center, prospective, randomized design, non-blind, non-inferiority controlled study on the optimization of GCs taper strategy for SLE-ITP maintenance therapy.In this study,sustained response rate and relapse rate within 3 months and 6 months were observed to judge the effectiveness of rapid GCs taper strategy, thus providing a basis for clinical GCs taper strategy.

Description:

Complete response was defined as a platelet count ≥100x10^9/L and the absence of bleeding and new other symptoms.Complete response would be confirmed by platelet counts on 2 separate occasions 7 days apart. Adequate glucocorticoids treatment was defined as at least a dose 50mg/day of prednisone (or equivalent glucocorticoids) for patients with weight less than 50kg, 60mg/day for patients with weight 50-75kg , 75mg/day for patients with weight more than 75kg. Adequate glucocorticoids were used for induction, and the total duration of adequate glucocorticoids treatment for patients enrolled was no longer than 3 weeks.Neither Thrombopoietin receptor agonist(TPO-RA) nor intravenous immunoglobulin(IVIG)were permitted in induction therapy or maintenance therapy.In addition to hydroxychloroquine(HCQ), other immunosuppressive agents are not permitted in induction therapy or maintenance therapy. After confirmation of complete response, the patients enrolled were randomly divided into two groups according to two different methods of GCs taper.
