Fig. 2 Proposed treatment regimen for platinum-sensitive, BRCA1/2-mutated or HRD positive recurrent ovarian cancer. There are now several clinical options of PARPi. As PARPi are more widely utilized there is significant need to delineate, prioritize, and standardize treatment strategies. Depicted is a hypothetical treatment plan for an ovarian cancer patient.

Fig. 3 PARPi resistance is mediated through a variety of targetable pathways. The FDA has approved three PARPi for ovarian cancer and as PARPi are commonly prescribed there will be an increase in acquired resistance. Currently, several targetable pathways (HR restoration, PI3K/AKT, miRNA) have been attributed to resistance.
