Pharmacology
Fostamatinib is a tyrosine kinase inhibitor with demonstrated activity against spleen tyrosine kinase (SYK); its major active metabolite R406 inhibits signal transduction of Fc-activating receptors and B-cell receptor, reducing antibody-mediated destruction of platelets.
Thrombopoietin receptor agonist; Fc-peptide fusion protein (peptibody) that binds and activates the TPO receptor to increase platelet production through a mechanism analogous to endogenous TPO.
