The new era of primary immune thrombocytopenia management in adults: A narrative review of current and emerging treatments

Abstract

The purpose of this review is to highlight the treatments currently available and those under- going evaluation in clinical trials for the treatment of ITP in order to achieve optimal use of the various existing ITP treatments. Specifically, we point out the indications for use of the various therapies available: corticosteroids, intravenous immunoglobulins (IVIG), thrombo- poietic agents (TPO-RAs), Syk inhibitors: Fostamatinib, antiCD20 monoclonal antibodies i.e. rituximab and the use of splenectomy in ITP. A review of the use of new drugs in ITP is also included in our manuscript: Neonatal Fc receptor (FcRn) antagonists; Bruton tyrosine kinase (BTK) inhibition; B-cell activating factor (BAFF) pathway inhibition; plasma cell depletion (an- tiCD38 monoclonal antibodies); new Syk inhibitors and complement inhibition. We believe that a reader with little knowledge of ITP can gain a clear understanding of the current treatment of ITP and its more or less immediate treatment prospects.

Keywords: Corticosteroids; ITP; Intravenous immunoglobulins (IVIG); Rituximab; Syk inhibitors; Thrombopoietic agents (TPO-RAs).
