ROSELLA: This study is evaluating the effectiveness of an investigational drug called relacorilant when given in combination with chemotherapy, compared to chemotherapy alone, in people with advanced, platinum-resistant, high-grade epithelial ovarian, primary peritoneal or fallopian-tube cancer who have had previous treatmentA Phase 3 Study of Relacorilant in Combination With Nab-Paclitaxel Versus Nab-Paclitaxel Monotherapy in Advanced, Platinum-Resistant, High-Grade Epithelial Ovarian, Primary Peritoneal, or Fallopian-Tube Cancer
