Renal impairment
Mild-to-moderate (CrCl ?30 mL/min): No dose adjustment required; minimally excreted by the kidneys
Severe (CrCl <30 mL/min) or hemodialysis: Unknown
Mode of Action
Second-generation orally administered thrombopoietin receptor agonist (TPO-RA)
Stimulates proliferation and differentiation of megakaryocytes from bone marrow progenitor cells, resulting in an increased production of platelets
Does not compete with TPO for binding to the TPO receptor and has an additive effect with TPO on platelet production
Precaution
Thrombotic/thromboembolic complications Thrombopoietin (TPO) receptor agonists associated with thrombotic and thromboembolic complications in patients with chronic liver disease or chronic ITP Portal vein thrombosis reported with chronic liver disease in patients treated with thrombopoietin (TPO) receptor agonists (ADAPT-1 and ADAPT-2 clinical trials) Consider the potential increased thrombotic risk when administering to patients with known risk factors for thromboembolism, including genetic prothrombotic conditions (eg, factor V Leiden, prothrombin 20210A, antithrombin deficiency, or protein C or S deficiency) Not to be administered to patients with chronic liver disease or chronic immune thrombocytopenia in an attempt to normalize platelet counts; thromboembolic events (arterial...

Pregnancy Category Note
Pregnancy Based on findings from animal reproduction studies, may cause fetal harm when administered to pregnant women In animal reproduction studies, administration resulted in adverse developmental outcomes when administered during organogenesis in rabbits and during organogenesis and the lactation period in rats However, these findings were observed at exposures based on AUC substantially higher than the AUC observed in patients at the recommended dose of 60 mg once daily Advise pregnant women of the potential risk to a fetus Lactation No data are available regarding the presence of the drug in human milk, the effects on the breastfed child, or...
