Registration Number
NCT05281068
Lead Sponsor
Peking University People's Hospital
Brief Summary

Randomized, open-label, multicenter study to compare the efficacy and safety of combination of iguratimod and danazol versus danazol for the treatment of adults with steroid-resistant/ relapse immune thrombocytopenia (ITP).

Detailed Description

The investigators are undertaking a parallel group, multicenter, randomized controlled trial of 100 adults with steroid-resistant/ relapse ITP in China. Patients were randomized to Iguratimod plus danazol and danazol monotherapy group. Platelet count, bleeding and other symptoms were evaluated before and after treatment. Adverse events are also recorded throughout the study.

Primary Outcome Measures
NameTimeMethod
Sustained response6 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.

Secondary Outcome Measures
NameTimeMethod
Complete remission6 months

The number of participants (responders) with platelet count\>=100x10\^9/L (CR) and the absence of bleeding.

Incidence of treatment-emergent adverse events6 months

Adverse events were scaled according to Common Terminology Criteria for Adverse Events (CTCAE) version 5.0.

Time to response6 months

Time to response was defined as the time from starting treatment to the time to achieve the response.

Duration of response6 months

Duration of response was measured from the achievement of response to the loss of response.

Partial remission6 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.
