Abstract

Introduction/Background Rucaparib has clinical activity in patients with recurrent OC with or without homologous recombination (HR) deficiency (HRD; eg, a BRCA mutation or high genomic loss of heterozygosity [LOH]) and is hypothesised to provide clinical benefit following frontline treatment. ATHENA 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: tumours with BRCA mutations express tumour-specific proteins (neoantigens), which attract PD-L1-expressing, tumour-infiltrating lymphocytes; ovarian tumours with HRD have more neoantigens relative to HR-proficient tumours and may respond to immune checkpoint inhibitors; rucaparib combined with anti-PD-1 demonstrated improved antitumour activity in an OC model; it is hypothesised that PARP inhibitor-induced DNA damage may increase neoantigens, regardless of HRD status.

Methodology Eligible patients must have completed frontline platinum-doublet chemotherapy and surgery and achieved an investigator-assessed response without disease progression or rising CA-125 at any time during frontline treatment. Cytoreductive surgery (R0 permitted) could have been completed prior to chemotherapy or following neoadjuvant chemotherapy. Patients will be randomised 4:4:1:1 to receive maintenance treatment in Arm A (oral rucaparib 600 mg BID + intravenous nivolumab 480 mg Q4W), Arm B (oral rucaparib + intravenous placebo), Arm C (oral placebo + intravenous nivolumab), or Arm D (oral placebo + intravenous placebo). Stratification factors include centrally determined tumour HRD status (BRCA mutant, non-BRCA mutant/LOH high, non-BRCA mutant/LOH low, or non-BRCA mutant/LOH indeterminate), posttreatment disease status, and timing of surgery. Investigator-assessed progression-free survival (RECIST v1.1; primary endpoint) will be compared between arms. Secondary endpoints include blinded independent central review of progression-free survival, overall survival, objective response rate, and safety.

Results Patients (n≈1000) will be enrolled at >270 sites worldwide.

Conclusion ATHENA is evaluating rucaparib + nivolumab as frontline maintenance treatment in patients with OC.
