We report final overall survival (OS; prespecified secondary endpoint), post hoc OS analysis by number of previous chemotherapy lines, and exploratory BRCA reversion mutation analysis. Two hundred sixty-six patients were randomly assigned 2:1 to olaparib tablets (300 mg twice daily; n 5 178) or physician’s choice of single-agent nonplatinum chemotherapy (pegylated liposomal doxorubicin, paclitaxel, gemcitabine, or topotecan; n 5 88) . OS was similar with olaparib versus chemotherapy (hazard ratio [HR], 1.07 [95% CI, 0.76 to 1.49]; P 5 .71, median 34.9 and 32.9 months, respectively, full analysis set) . OS with olaparib was favorable in patients with two previous chemotherapy lines (HR, 0.83 [olaparib v chemotherapy][95% CI, 0.51 to 1.38]; median 37.9 v 28.8 months); however, a potential detrimental effect was seen in patients with at least three previous chemotherapy lines (HR, 1.33 [95% CI, 0.84 to 2.18]; median 29.9 v 39.4 months) . BRCA reversion mutations might have contributed to this finding. No patient randomly assigned to olaparib with a BRCA reversion mutation detected at baseline (6 of 170 [3.5%]) achieved an objective tumor response.  \nACCOMPANYING CONTENT  \n Data Supplement  Protocol  \nAccepted October 8, 2024 Published December 12, 2024  \nJ Clin Oncol 43:1408-1416 © 2024 by American Society of Clinical Oncology  \nView Online Article  \nCreative Commons Attribution Non-Commercial No Derivatives 4.0 License  \nINTRODUCTION  \nOlaparib, a poly(ADP-ribose) polymerase (PARP) inhibitor, received US Food and Drug Administration–accelerated approval as a treatment for advanced ovarian cancer (OC), germline (g) BRCA1 and/or BRCA2 mutation (BRCAm) and ≥3 prior chemotherapy lines based on Study 421-3; however, aconfirmatory trial was required.
