Summary

This trial is testing a new combination therapy for metastatic triple-negative breast cancer.

Who is the study for?
This trial is for adults with stage IV breast cancer that hasn't spread to the brain, who haven't had recent cancer treatments or surgeries, and are not pregnant. They must have a certain level of health, including stable blood sugar levels and an ECOG performance status of 0-1 (fully active or restricted in physically strenuous activity but ambulatory).
What is being tested?
The study tests Sacituzumab Govitecan combined with Talazoparib in patients with metastatic triple-negative breast cancer. It aims to see how well these drugs work together against this aggressive form of cancer.
What are the potential side effects?
Possible side effects include nausea, fatigue, low blood cell counts leading to increased infection risk or bleeding problems, hair loss, neuropathy (nerve pain or tingling), and potential allergic reactions to the drug components.
