Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a prospective, single-arm study to investigate the efficacy and safety of the combination of fixed low-dose eltrombopag plus recombinant human thrombopoietin (rhTPO) as treatment for corticosteroid-resistant or relapsed immune thrombocytopenia (ITP) patients during the COVID-19 pandemic.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Eltrombopag, a small molecule agonist of thrombopoietin receptor (TPO-RA), was recommended as the subsequent treatment for ITP patients, which also already showed robust efficacy.Recombinant human thrombopoietin (rhTPO) is a full-length glycosylated-TPO produced by Chinese hamster ovary cells, which showed its effectiveness in ITP in a variety of studies.

Both eltrombopag and rhTPO demonstrated good safety in ITP patients. Because of their non-immunosuppressive nature, both of them serve as a reasonable choice during the global COVID-19 pandemic.

Since they increase the number of platelets through different mechanisms, and previous studies demonstrated that they might exert synergic effect. The investigators hypothesized that the combination of these two agents could be a promising option for treatment of corticosteroid-resistant or relapsed ITP patients.
