Purpose

The primary objective of the study is to compare sacituzumab tirumotecan combined with pembrolizumab to pembrolizumab alone with respect to overall survival (OS). The primary hypothesis is that the combination of sacituzumab tirumotecan and pembrolizumab is superior to pembrolizumab alone with respect to OS. All participants who have completed the first course of pembrolizumab may be eligible for up to an additional 9 cycles of pembrolizumab monotherapy if there is blinded independent central review (BICR)-verified progressive disease by Response Evaluation Criteria In Solid Tumors version 1.1 (RECIST 1.1) after initial treatment.

Experimental
Pembrolizumab + Sacituzumab tirumotecan
Participants receive sacituzumab tirumotecan via intravenous (IV) infusion on Days 1, 15 and 29 of each 6-week cycle + 400 mg Pembrolizumab every 6 weeks (q6w) via IV infusion on Day 1 of each 6-week cycle for 18 cycles. Additionally, participants receive diphenhydramine (or equivalent), an 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.
