Class/mechanism: Thrombopoietin (TPO/cMpl) receptor agonist. Romiplostim is an Fc-peptide fusion protein (peptibody) that interacts with the TPO receptor to trigger downstream signal cascades that ultimately stimulate platelet production by promoting proliferation and differentiation of megakaryocytes from bone marrow progenitor cells.
For conciseness and simplicity, HemOnc.org currently will focus on treatment regimens and not list information such as: renal/hepatic dose adjustments, metabolism (including CYP450), excretion, monitoring parameters (although this will be considered for checklists), or manufacturer. Instead, for the most current information, please refer to your preferred pharmacopeias such as Micromedex, Lexicomp, UpToDate (courtesy of Lexicomp), or the prescribing information.
