A Single-arm, Multicenter Clinical Study of Becotatug Vedotin Combined With Zimberelimab in the Treatment of Recurrent and Metastatic Cervical Cancer, Vulvar Cancer and Vaginal Cancer

Summary

This is a prospective, multicenter, single-arm clinical trial investigating Becotatug Vedotin in combination with Zimberelimab for the treatment of patients with recurrent and metastatic cervical cancer, vulvar cancer, and vaginal cancer. A total of 30 patients are expected to be enrolled. The study consists of a screening period (within 28 days), a treatment period, and a follow-up period (safety follow-up and survival follow-up). Trial treatment will continue until the patient has received Becotatug Vedotin for 1 year, or until disease progression, unacceptable toxicity, withdrawal of informed consent, or death, whichever occurs first. Subjects will sign the informed consent form and undergo baseline examinations during the screening period. Patients who meet the inclusion and exclusion criteria will enter the treatment period. All subjects will complete the relevant examinations specified in the protocol during treatment to observe safety, tolerability, and efficacy.
