Abstract:

Immune thrombocytopenia (ITP) is an acquired autoimmune disease involving multiple mechanisms, which leads to platelet destruction and macrocytosis and impaired platelet production, mainly manifested as decreased platelet levels and a tendency to bleed, which seriously affects the quality of life and prognosis of patients. Treatment of ITP aims to increase platelet count (PLT), reduce the incidence of fatal bleeding, and improve quality of life. To improve efficacy, reduce adverse reactions and the advent of thrombopoietin receptor agonists (TPO-RAs) prompted a shift in ITP treatment to combination therapy. Hetrombopag is a novel oral second generation small molecule, non-peptide TPO-RAs that binds to the transmembrane domain of thrombopoietin receptor (TPO-R), stimulates megakaryocyte proliferation and differentiation, and promotes platelet production. Hetrombopag combined with other drugs (glucocorticoid, rhTPO and cyclosporine A) in the treatment of ITP can achieve multi-target treatment, through the integration of different drug mechanisms of action, can more comprehensively intervene in the pathogenesis of ITP, so as to improve the therapeutic effect, so this article reviews the clinical research progress of hetrombopag combination in the treatment of ITP.

Key words: hetrombopag, immune thrombocytopenia, combination drug, glucocorticoids, rhTPO, cyclosporine A
