What this study is
Researchers are looking for new ways to treat advanced, high-grade ovarian cancer (OC). Advanced means the cancer has spread to other parts of the body (metastatic) and may not be removed with surgery. High-grade means the cancer cells grow and spread quickly. This trial includes types of OC that started in cells that cover the ovaries, in the lining of the belly, or in the fallopian tubes.
The usual treatment for high-grade OC may include one or both of these:
- Chemotherapy, which is a treatment that uses medicine to destroy cancer cells or stop them from growing.
- Bevacizumab, which is a targeted therapy that works to control how specific types of cancer cells grow and spread and targets tumor blood vessels.
Researchers want to learn about the trial medicine, raludotatug deruxtecan (also called R-DXd or MK-5909), when given with and without bevacizumab and how participants respond to it. R-DXd is an antibody drug conjugate (ADC). An ADC is a type of medicine that attaches to a specific target on cancer cells and delivers treatment to destroy those cells.
The goals of this trial are to learn if participants who receive R-DXd, with or without bevacizumab, live longer overall and without their cancer growing or spreading compared to those who receive usual treatment.
