Poly-ADP-ribosepolymerase inhibitors (PARPis) are the most active and interesting therapies approved for the treatment of epithelial ovarian cancer. They have changed the clinical management of a disease characterized, in almost half of cases, by extreme genetic complexity and alteration of DNA damage repair pathways, particularly homologous recombination (HR) deficiency. In this review, we provide an updated overview of the available results of recent clinical trials on the three Food and Drug Administrationand European Medicines Agency approved PARPis in ovarian cancer: olaparib, niraparib, and rucaparib. Furthermore, we anticipate the future perspective of combination regimens with antiangiogenic, immunocheckpoint inhibitors, and other biological agents as strategies to overcome resistance mechanisms, potentiate the therapeutic efficacy, and expand their clinical use in non-HR deficient tumors.
