  1. aNone of the patients received prior immune-checkpoint inhibitor therapy.
  2. bPlatinum sensitivity was defined as per the definition utilized in ovarian cancer, based on platinum free interval time. Platinum sensitive: disease relapse occurs >6 months from last dose of platinum chemotherapy; Platinum resistant: Disease relapse occurs <6 months from last dose of platinum chemotherapy.
