No arrhythmia known to increase the risk of thrombotic events (e.g. atrial fibrillation), or patients with a QT >450msec or QTc > 480 for patients with a Bundle Branch Block;
  • Researchers believe that patients should not participate in the test of any other condition.

Interventions

DRUGAvatrombopag

The subjects will initiate treatment with 60 mg/d Avatrombopag. Platelet counts is obtained weekly and dose adjustment should be done according to platelet counts, and maximum dose should not exceed 60 mg daily. Subjects whose platelet count ≤100×109/L，the Avatrombopag dose will maintain. If platelet count \>100×109/L for 2 weeks, the subjects need to reduce the dose of Avatrombopag to the next lower dose or lower frequency. If subjects whose platelet count exceeds 100×109/L for 4 weeks，already have reduced the dose of Avatrombopag to 20mg once every other day or lower frequency during the treatment period, Avatrombopag can be stopped for observation, until platelet counts fall below 100×109/L. If the subjects do not need further chemotherapy or radiotherapy, the subjects can taper off Avatrombopag if the platelet is greater than 50×109/L.
