NCT ID NCT06840483

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This Phase 2 study tests a drug called zelenectide pevedotin in 66 people with advanced breast cancer that has a specific gene change (NECTIN4 amplification). The study includes two groups: one with hormone receptor-positive/HER2-negative cancer and one with triple-negative breast cancer. The main goal is to see if the drug shrinks tumors, while also checking for side effects.
