Experimental: Iguratimod and Danazol
Iguratimod is given at a dose of 25 mg bid. Danazol is given at 200mg bid for 12 weeks.
|
Drug: Iguratimod
Oral iguratimod (25 mg twice daily) for 12 weeks. Iguratimod is a new drug for the treatment of rheumatoid arthritis (RA) and osteoarthritis (OA), which was filed for marketing in Japan in 2003. It can significantly reduce the inflammatory response, not only selectively inhibit COX-2, but also inhibit the production of inflammatory cytokines, tumor necrosis factor, lymphocytes and immunoglobulins, and has an autoimmunomodulatory effect; it has a rapid onset of action, better efficacy and fewer adverse effects than existing drugs, and is effective in patients for whom other drugs are ineffective. It has been reported in the literature that in vitro iguratimod can inhibit the activity of nuclear factor-κB (NF-κB), which in turn inhibits the production of inflammatory cytokines (interleukin-1, interleukin-6, interleukin-8, tumor necrosis factor alpha). Iguratimod also interacts directly with mouse and human B cells in vitro to inhibit the production of immunoglobulins.

- Sustained response [ Time Frame: 6 months ]The maintenance of platelet count ≥ 30 x 10^9/L, at least 2-fold increase of the baseline count, the absence of bleeding, and no need for rescue medication at the 6-month follow-up. Interim analysis was scheduled at 50% through recruitment.
- Complete remission [ Time Frame: 6 months ]The number of participants (responders) with platelet count>=100x10^9/L (CR) and the absence of bleeding.
- Partial remission [ Time Frame: 6 months ]The number of participants (responders) with platelet count >=30x10^9/L and at least a 2-fold increase in the baseline count (PR) without the administration of any other platelet increasing therapy.
- Time to response [ Time Frame: 6 months ]Time to response was defined as the time from starting treatment to the time to achieve the response.
- Duration of response [ Time Frame: 6 months ]Duration of response was measured from the achievement of response to the loss of response.
- Incidence of treatment-emergent adverse events [ Time Frame: 6 months ]Adverse events were scaled according to Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.
