Sacituzumab Tirumotecan (MK-2870) in Post Platinum and Post Immunotherapy Endometrial Cancer (MK-2870-005)

Purpose

Researchers are looking for new ways to treat people with endometrial cancer (EC) who have previously received treatment with platinum based therapy (a type of chemotherapy) and immunotherapy. Immunotherapy is a treatment that helps the immune system fight cancer. This clinical study will compare MK-2870 sacituzumab tirumotecan to chemotherapy. The goal of the study is to learn if people who receive MK-2870 sacituzumab tirumotecan live longer overall and without the cancer getting worse compared to people who receive chemotherapy.

Experimental
Sacituzumab tirumotecan 		Participants will receive 4 mg/kg of sacituzumab tirumotecan via intravenous (IV) infusion on Day 1 of each 14-day cycle. Additionally, participants receive diphenhydramine (or equivalent), a Histamine (H2 antagonist) of investigator's choice, acetaminophen (or equivalent), and dexamethasone (or equivalent) per each drug's product label prior to the first 4 infusions of sacituzumab tirumotecan. At subsequent infusions, the H2 antagonist and dexamethasone are optional, at the discretion of the investigator.
