Purpose

Researchers are looking for new ways to treat metastatic cervical cancer. Cervical cancer is cancer in the cervix, the lower part of the uterus (womb). Metastatic means the cancer has spread to other parts of the body. Researchers want to learn about giving the study medicine sacituzumab tirumotecan (also called sac-TMT or MK-2870) along with pembrolizumab and bevacizumab treatments. Sac-TMT is an antibody drug conjugate, which is a type of medicine that attaches to specific targets on cancer cells and delivers treatment to destroy those cells. The goals of this study are to learn: - About the safety of sac-TMT with pembrolizumab and bevacizumab, and if people tolerate them when given together, and - If people who receive sac-TMT and pembrolizumab, with or without bevacizumab, live longer overall or without their cancer getting worse as compared to those who receive standard treatment

Experimental
Part 1 Safety Run-in: Sac-TMT + Pembrolizumab + Bevacizumab
Participants will receive sac-TMT 4 mg/kg every 2 weeks (q2w) and pembrolizumab 400 mg every 6 weeks (q6w) for up to 14 cycles (up to approximately 19 months). Bevacizumab 15 mg/kg every 3 weeks (q3w) will be administered until a treatment discontinuation criterion is met. Each cycle will be 6 weeks long.

Detailed Description

This is a 2-part study. In Part 1 Safety Run-in, eligible participants will be allocated to treatment with sac-TMT + pembrolizumab + bevacizumab. In Part 2, all participants receive standard of care induction treatment. Eligible participants whose cancer does not progress then begin maintenance treatment and are randomized to receive pembrolizumab or sac-TMT + pembrolizumab. All participants in Part 2 maintenance treatment may also receive bevacizumab at the investigator's discretion.
