NCIt definition : The maleate salt form of avatrombopag, an orally available platelet thrombopoietin
receptor (TPOR; MPL) agonist, with potential megakaryopoiesis stimulating activity.
Upon administration, avatrombopag binds to and stimulates TPOR, which may lead to
the proliferation and differentiation of megakaryocytes from bone marrow progenitor
cells. This increases the production of platelets and may prevent chemotherapy-induced
thrombocytopenia (CIT). TPOR is a cytokine receptor and member of the hematopoietin
receptor superfamily.;
