Decitabine Combining Dexamethasone Versus Dexamethasone in Management of ITP

August 13, 2018 updated by: Ming Hou, Shandong University

A Multicenter Prospective Randomized Study of Dexamethasone Combined With Decitabine Versus Dexamethasone in the Treatment of Newly Diagnosed Primary Immune Thrombocytopenia (ITP)

The project was undertaking by Qilu Hospital of Shandong University and other 18 well-known hospitals in China. In order to report the efficacy and safety of decitabine combining with dexamethasone for the treatment of adults with immune thrombocytopenia (ITP), compared to dexamethasone alone .

Detailed Description

The investigators anticipate to undertaking a parallel group, multicentre, randomised controlled trial of 200 ITP adult patients from 19 medical centers in China. One part of the participants are randomly selected to receive dexamethasone (given 40mg/d for 4 consecutive days as a cycle , If platelet count remained below 30 × 109/L or there were bleeding symptoms by day 10, an additional cycle of dexamethasone was given) combining with decitabine (given intravenously at a dose of 3.5mg/m2/d for 4 consecutive days as a cycle and repeated every 2 weeks for 3 cycles), the others are selected to receive dexamethasone therapy(given 40mg/d for 4 consecutive days as a cycle, If platelet count remained below 30 × 109/L or there were bleeding symptoms by day 10, an additional cycle of dexamethasone was given). Platelet count, bleeding and other symptoms were evaluated before and after treatment, adverse events are also recorded throughout the study in order to report the efficacy and safety of the combination therapy compared to dexemathasone alone therapy for the treatment of adults with ITP.
