What this Trial Is About

Researchers are evaluating if ifinatamab deruxtecan I-DXd, an antibody-drug conjugate, can treat advanced esophageal squamous cell carcinoma ESCC. This treatment works by attaching to proteins on cancer cells and delivering therapy to destroy them. The study aims to find out how many participants experience tumor shrinkage or disappearance after receiving I-DXd. Participants will receive I-DXd through intravenous infusion every 3 weeks. Treatment continues until the cancer progresses or other criteria for stopping are met. The study is part of a master screening protocol called KEYMAKER-U06 and focuses on participants with unresectable locally advanced or metastatic ESCC who have had prior systemic therapy. During the study, participants will be monitored for tumor response using objective response rate over about 14 months. Researchers will also measure duration of response, progression-free survival, overall survival, and track adverse events for up to 18 to 26 months. Participants undergo regular assessments including imaging and safety evaluations throughout their participation, which may last several months.
