Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a global, multicenter, open-label study that aims to assess the efficacy and safety of zelenectide pevedotin in participants with NECTIN4-amplified recurrent, unresectable, or metastatic breast cancer who have received prior therapy (see inclusion criteria below). The study will comprise of 2 cohorts. Cohort A will include participants with hormone receptor positive/ human epidermal growth factor receptor 2 negative \[HR+/HER2-\] breast cancer, whereas Cohort B will include participants with triple-negative breast cancer (TNBC).
