  1. ECOG Eastern Cooperative Oncology Group, PS performance status.
  2. aHistology based on information provided at enrollment. Pathology re-review triggered by molecular findings reclassified 11 cases as non-high-grade serous or Grade 2/3 endometrioid histology (see Supplementary Table S12).
  3. bReceipt of <3 prior chemotherapy regimens was considered a protocol deviation.
