New hope for Tough-to-Treat breast cancer: experimental drug enters final testing phase

This study is testing whether an experimental drug called SKB264 works better than standard chemotherapy for people with advanced triple-negative breast cancer that has continued to grow despite at least two prior treatments. The trial will involve about 254 adults whose cancer cannot be surgically removed and has spread or returned. Researchers will compare how long patients live without their cancer getting worse on the new drug versus on other chemotherapy options chosen by their doctor.
