Study Arms (2)

Optimized rhTPO treatment

EXPERIMENTAL

The study in a 2:1 randomization ratio (117 subjects to rhTPO group).

Drug: rhTPO

Eltrombopag treatment

ACTIVE COMPARATOR

The study in a 2:1 randomization ratio (58 subjects to Eltrombopag group).

Drug: Eltrombopag

Interventions

rhTPODRUG

initial therapy: rhTPO s.c, 300 or 600U/kg daily based on baseline platelet count; maintenance therapy: rhTPO s.c, 300 \~ 600U/kg every other day depends on platelet count.

Also known as: Recombinant human thrombopoietin, TPIAO
Optimized rhTPO treatment

initial therapy: Eltrombopag oral, 25 or 50mg daily based on baseline platelet count; maintenance therapy: Eltrombopag oral, 25 \~ 75mg daily or every other day depends on platelet count.

Also known as: Eltrombopag olamine
Eltrombopag treatment
