Active Ingredient History
Lusutrombopag (trade name Mulpleta) is an orally bioavailable, small molecule thrombopoietin (TPO) receptor agonist being developed by Shionogi for chronic liver disease (CLD) patients with thrombocytopenia prior to elective invasive surgery. Lusutrombopag acts selectively on the human TPO receptor and activates signal transduction pathways that promote the proliferation and differentiation of bone marrow cells into megakaryocytes, thereby increasing platelet levels. In September 2015, Lusutrombopag received its first global approval in Japan for the improvement of CLD-associated thrombocytopenia in patients scheduled to undergo elective invasive procedures. Oral Lusutrombopag is rapidly absorbed, with a median time to maximum serum concentration (Tmax) of 3.8–4.0 h in healthy subjects administered single doses of oral Lusutrombopag 1, 2 or 4 mg, and 6 h in CLD patients with thrombocytopenia administered oral Lusutrombopag 3 mg once daily for 7 days. The major metabolic pathway for Lusutrombopag appears to be omega- and beta-oxidation. Lusutrombopag is a substrate of breast cancer resistance protein and P-glycoprotein, according to in vitro data.
