Summary of Clinical Use
Fostamatinib (as the disodium hexahydrate salt) received FDA approval for the treatment of chronic immune thrombocytopenia (ITP) [5] in April 2018, in particular for the treatment of patients with an inadequete response to previous treatment.
Fostamatinib has completed Phase 3 clinical trials for rheumatoid arthritis [3] (NCT01197534 & NCT01197755), and Phase 2 for a range of solid tumours (NCT00923481).
Mechanism Of Action and Pharmacodynamic Effects
The active moeity, tamatinib inhibits Syk kinase-mediated IgE- and IgG-mediated activation of Fc gamma receptor signaling, resulting in inhibition of the activation of mast cells, macrophages, and B-cells and related inflammatory responses and tissue damage [1,4].
