Background:

Avatrombopag(AKR-501; AS1670542) is a novel orally-active thrombopoietin(TPO) receptor agonist with EC50 of 3.3 nM.EC50 value: 3.3 nM [1]Target: TPO receptor agonistin vitro: AKR-501 specifically targeted the TPO receptor and stimulated megakaryocytopoiesis throughout the development and maturation of megakaryocytes just as rhTPO did. AKR-501, however, was shown to be effective only in humans and chimpanzees with high species specificity [1]. AS1670542 has 50% effective concentration values for cell proliferation with AS1670542 or eltrombopag were 1.9 and 13nM, respectively, while those for megakaryocyte colony formation from human cord blood CD34(+) cells with AS1670542 or eltrombopag were 260 and 950nM, respectively [2].in vivo: Daily oral administration of AKR-501 dose-dependently increased the number of human platelets in in human platelet producing non-obese diabetic/severe combined immunodeficiency (NOD/SCID) mice transplanted with human fetal liver CD34(+) cells, with significance achieved at doses of 1 mg/kg and above. The peak unbound plasma concentrations of AKR-501 after administration at 1 mg/kg in NOD/SCID mice were similar to those observed following administration of an active oral dose in human subjects [1]. AS1670542 significantly increased the number of human platelets in non-obese diabetic/severe combined immunodeficiency (NOD/SCID) mice with transplanted human hematopoietic stem cells at 0.3 (P<0.05); in contrast, while administration of eltrombopag also increased the numbers of these platelets at 30mg/kg/day (P=0.058), no statistical significance was noted in the increase [2].
