Methods We evaluated the number of platelet elevations according to the number of lusutrombopag administrations. We also evaluated the correlation between the highest software-predicted platelet count and the platelet count measured in actual clinical practice. Patients This retrospective study included 236 patients treated with lusutrombopag at 11 medical institutions in Japan. Results The platelet count increased with the number of lusutrombopag administrations (1, 2, 3, 4, >4) in all groups, and no significant difference was found among the groups (p = 0.169). In all groups, the platelet counts reached their highest levels at 8-14 days after treatment with lusutrombopag (p = 0.243). There was a correlation between the highest software-predicted platelet count and the platelet count measured in actual clinical practice in all dose frequency groups; however, the correlation was the strongest in the one-dose group (r = 0.74, p <0.0001).
