Abstract 263TiP

Background

Rucaparib has clinical activity in patients with recurrent ovarian cancer with or without homologous recombination deficiency (HRD; eg, a BRCA mutation or high genome-wide loss of heterozygosity) and is hypothesised to provide clinical benefit following frontline treatment. ATHENA (NCT03522246) is evaluating rucaparib + nivolumab as maintenance treatment following frontline platinum-based chemotherapy in patients with newly diagnosed, high-grade ovarian, fallopian tube, or primary peritoneal cancer. The rationale for this combination includes the following: tumours with deleterious BRCA mutations or HRD express tumour-specific neoantigens, which attract PD-L1–expressing, tumour-infiltrating lymphocytes; rucaparib + anti-PD-1/PD-L1 demonstrated activity in a syngeneic ovarian cancer model; and PARP inhibitor–induced DNA damage may create a more antigenic tumour microenvironment regardless of HRD status.

Trial design

Patients are required to have completed cytoreductive surgery and achieved an investigator-assessed response to frontline, platinum-based doublet chemotherapy without disease progression or rising CA-125 during frontline treatment. Patients are randomised 4:4:1:1 to receive maintenance treatment in Arm A (oral rucaparib 600 mg twice daily + intravenous [IV] nivolumab 480 mg on day 1 of every 4-week cycle), Arm B (oral rucaparib + IV placebo), Arm C (oral placebo + IV nivolumab), or Arm D (oral placebo + IV placebo). Stratification factors include centrally determined tumour HRD status, posttreatment disease status, and timing of surgery. Investigator-assessed progression-free survival (RECIST v1.1; primary endpoint) will be compared among arms. Secondary endpoints include blinded independent central review of progression-free survival, overall survival, investigator-assessed objective response rate, duration of response, and safety. Enrolment is ongoing; patients (n≈1000) will be enrolled at > 270 sites worldwide.
