In recent years, the advent of poly(ADP-ribose) polymerase(PARP) inhibitors is one of the important breakthroughs in the field of tumor-targeted therapy, and its therapeutic effect on ovarian cancer is quite significant Pamiparib is a potent, selective, oral PARP 1/2 inhibitor. In preclinical models, pamiparib demonstrated PARP-DNA complex trapping, brain penetration, antitumor activity, and inhibition of PARylation.
Therefore, at least 50 patients using pamiparib will be included. Before and after treatment, the laboratory examination data ，blood concentration ，combined medication and adverse events of the patients will be collected. The population pharmacokinetic model of pamiparib was established to evaluate the correlation between pharmacokinetic parameters and adverse reactions.
