About

Recently, histone deacetylase inhibitors (HDACi) has been used for their anti-inflammatory and immunomodulatory activities. It has been shown that HDACi can alleviate graft-versus-host disease by enhancing the number and function of Foxp3+ Tregs. Our group found that low-dose HDACi alleviated thrombocytopenia in both passive and active murine models of ITP. Furthermore, low-dose HDACi attenuated macrophage phagocytosis of antibody-coated platelets, stimulated production of natural Foxp3+ Tregs, promoted peripheral conversion of T cells into Tregs, and restored Treg suppressive function in vivo and in vitro. The project was undertaking by Qilu Hospital of Shandong University and other 10 well-known hospitals in China. In order to report the efficacy and safety of the low dose chidamide combined with high-dose dexamethasone versus high-dose dexamethasone in the management of ITP.

Full description

Primary immune thrombocytopenia (ITP) is an autoimmune bleeding disorder with low platelet count. Low-dose HDACi alleviated thrombocytopenia in both passive and active murine models of ITP. In this multicentre, open-label, randomized controlled trial, newly diagnosed ITP patients will be enrolled from 11 tertiary medical centres in China. Participants will be randomly assigned into the combination group or the monotherapy group by masked statisticians in a 1:1 ratio. The primary endpoints are sustained response at month 6. The secondary outcomes include initial response, time to response, duration of response, bleeding score, health-related quality of life assessment, and safety issue. This study will compare the efficacy and safety of low dose chidamide combined with high-dose dexamethasone versus high-dose dexamethasone monotherapy in adults with primary immune thrombocytopenia.
