Clovis Oncology’s Rubraca® (Rucaparib) as First-Line Maintenance Treatment Improves Progression-Free Survival in Women with Advanced Ovarian Cancer Across Disease Risk Subgroups

BOULDER, Colo.--(BUSINESS WIRE)--Sep 11, 2022--

Clovis Oncology, Inc. (NASDAQ: CLVS), today announced results from a subgroup analysis of data from the monotherapy comparison of the randomized, Phase 3 ATHENA (GOG-3020/ENGOT-ov45) trial (ATHENA-MONO). These data showed that Rubraca as first-line maintenance treatment improved progression-free survival (PFS) versus placebo across disease risk subgroups including surgical outcome, response to first-line chemotherapy, and additional analyses in other subgroups. The data were presented by Rebecca S. Kristeleit, MD, PhD, of Guy’s and St. Thomas’ NHS Foundation Trust in London and lead ENGOT/NCRI National Cancer Research Institute ( https://www.ncri.org.uk/ ) investigator of the ATHENA trial as a Mini Oral abstract at the European Society of Medical Oncology (ESMO) Congress 2022 in Paris.

“These additional results from the ATHENA-MONO analysis of the Phase 3 ATHENA trial demonstrate that rucaparib should be considered a new first-line maintenance treatment option for women with advanced ovarian cancer,” Dr. Kristeleit said. “In this analysis, rucaparib prolonged progression-free survival for patients with or without high risk factors for progression, irrespective of molecular characteristics, adding to our understanding of the efficacy of rucaparib in the broadest population of patients assessed in a clinical trial for first-line PARP inhibitor monotherapy.”

ATHENA is a double-blind, placebo-controlled, Phase 3 trial of Rubraca in first-line ovarian cancer maintenance treatment. It has two parts which are statistically independent. The results presented at ESMO are from the ATHENA-MONO part (Rubraca versus placebo), with results from the ATHENA-COMBO part (Rubraca plus nivolumab versus Rubraca) expected in Q1 2023.
