Brief Summary

Niraparib brings a better prognosis to those with advanced ovarian cancer and has been approved by the Food and Drug Administration（FDA ）and National Medical Products Administration（NMPA）as one of the maintenance therapies for the advanced ovarian cancer patients. Thrombocytopenia is one of the adverse effects of Niraparib, with a 61% overall incidence and 34% of the grade 3\~4 incidence. Thrombocytopenia may cause suspension or dose reduction of Niraparib which will affect the therapeutic effect of the drug. At present, the drugs recommended by the guidelines for the treatment of thrombocytopenia are recombinant thrombopoietin (rhTPO), recombinant interleukin 11 (rhIL-11), TPO receptor agonist (TPO-RA). Hetrombopag is one of the TPO-RA, which is recommended by the Chinese expert consensus to cure the thrombocytopenia caused by poly adenosinediphosphate ribose polymerase（PARP） inhibitors, including Niraparib. However, is it effective when it is used as the primary prevention during the maintenance therapy of Niraparib? This single-arm study aims to explore the efficacy and safety of hetrombopag for the prevention of thrombocytopenia caused by Niraparib maintenance therapy in advanced ovarian cancer patients. 34 patients will be recruited and they will take hetrombopag 5mg per day for 8 weeks when they initiate the maintenance therapy with Niraparib. The primary endpoint of this study is the rate of thrombocytopenia according to Common Terminology Criteria for Adverse Events 5.0（CTCAE5.0）.
