Indications

MULPLETA is indicated for the treatment of thrombocytopenia in adult patients with chronic liver disease who are scheduled to undergo a procedure. MULPLETA is a thrombopoietin receptor agonist indicated for the treatment of thrombocytopenia in adult patients with chronic liver disease who are scheduled to undergo a procedure. ( 1 )

Mises en garde et précautions d’emploi

Thrombotic/Thromboembolic Complications: MULPLETA is a thrombopoietin (TPO) receptor agonist, and TPO receptor agonists have been associated with thrombotic and thromboembolic complications in patients with chronic liver disease. Monitor platelet counts and for thromboembolic events and institute treatment promptly. ( 5.1 )

5.1Thrombotic/Thromboembolic Complications

MULPLETA is a thrombopoietin (TPO) receptor agonist, and TPO receptor agonists have been associated with thrombotic and thromboembolic complications in patients with chronic liver disease. Portal vein thrombosis has been reported in patients with chronic liver disease treated with TPO receptor agonists. Portal vein thrombosis was reported in 1% (2 of 171) of MULPLETA-treated patients and 1% (2 of 170) of placebo-treated patients in 3 randomized, double-blind trials and was identified post-procedure in protocol-specified imaging.

The thromboses were not associated with a marked increase in platelet count. Consider the potential increased thrombotic risk when administering MULPLETA to patients with known risk factors for thromboembolism, including genetic pro-thrombotic conditions (Factor V Leiden, Prothrombin 20210A, Antithrombin deficiency, or Protein C or S deficiency). In patients with ongoing or prior thrombosis or absence of hepatopetal blood flow, MULPLETA should only be used if the potential benefit to the patient justifies the potential risk.

8.1Pregnancy Risk Summary

There are no available data on MULPLETA in pregnant women to inform the drug-associated risk. In animal reproduction studies, oral administration of lusutrombopag to pregnant rats during organogenesis and the lactation period resulted in adverse developmental outcomes. These findings were observed at exposures based on AUC that were substantially higher than the AUC observed in patients (approximately 89 times) at the recommended clinical dose of 3 mg once daily .

Advise pregnant women of the potential risk to a fetus (see Data ) . The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the general population in the United States, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Data Animal Data In an embryo-fetal development study in rats, lusutrombopag was orally administered during organogenesis at doses of 4, 12.5, 40, and 80 mg/kg/day. Low body weight and a decrease in the number of ossified sternebrae were noted in fetuses at 80 mg/kg/day (approximately 251 times the AUC observed in patients at the recommended clinical dose of 3 mg once daily). Minor skeletal variations (supernumerary ribs) were observed at doses of 4 mg/kg/day (approximately 23 times the AUC observed in patients at the recommended clinical dose of 3 mg once daily).

In an embryo-fetal development study in rabbits following oral administration of lusutrombopag at doses up to 1000 mg/kg/day, no effect of lusutrombopag was observed on any parameter of embryo-fetal development. In a pre- and postnatal development study in rats at oral doses of 1, 4, 12.5, and 40 mg/kg/day, there were adverse effects of lusutrombopag on postnatal development at 40 mg/kg/day (approximately 230 times the AUC observed in patients at the recommended clinical dose of 3 mg once daily).

The effects included prolongation of the gestation period in dams, low viability before weaning, delayed postnatal growth (delayed negative geotaxis, delayed eyelid opening, or low pup body weight), abnormal clinical signs (prominent annular rings on the tail after weaning), low fertility index, a low number of corpora lutea or implantations, and increased pre-implantation loss. The incidence of short thoracolumbar supernumerary ribs on postnatal Day 4 of F1 pups was high at doses of 12.5 mg/kg/day or more (approximately 89 times the AUC observed in patients at the recommended clinical dose of 3 mg once daily).
