ClinConnect Summary

This clinical trial is studying a new treatment approach for women with early or locally advanced triple-negative breast cancer (TNBC). The goal is to see if combining a medication called ivonescimab with standard chemotherapy before surgery can help improve treatment outcomes. Eligible participants are women aged 18 to 75 who have been diagnosed with TNBC and have not received any prior treatment. They will receive 12 doses of ivonescimab along with chemotherapy before surgery and then continue with 14 more doses of ivonescimab after surgery.

Participants can expect to have regular check-ups during the trial to monitor their health and response to the treatment. The main focus of this study is to see how many participants have no signs of cancer in tissue samples after treatment. In addition to this, researchers will also keep track of how long participants stay free of disease after treatment. It's important for potential participants to know that they will need to meet specific health criteria to join, and they should be willing to follow the study plan closely. The trial is not yet recruiting, so interested individuals will need to wait for the study to start.
