A Study to Evaluate the Efficacy and Safety of Sacituzumab Tirumotecan (MK-2870) Maintenance Treatment Versus Standard of Care in Participants With Platinum-sensitive Recurrent Ovarian Cancer (MK-2870-022/TroFuse-022/ENGOT-ov84/GOG-3103)
A Phase 3, Randomized, Open-label, Multicenter Study to Evaluate the Efficacy and Safety of Sacituzumab Tirumotecan Maintenance Treatment With or Without Bevacizumab Versus Standard of Care After Second-line Platinum-based Doublet Chemotherapy in Participants With Platinum-sensitive Recurrent Ovarian Cancer (TroFuse-022/ENGOT-ov84/GOG-3103)

Summary
The main goals of this study are to learn about the safety of sacituzumab tirumotecan with bevacizumab and if people tolerate it; and if people who take sacituzumab tirumotecan with or without bevacizumab live longer without the cancer getting worse than those who receive standard of care treatment.
