This study is looking at a drug called sacituzumab tirumotecan (Sac-TMT) to see if it helps treat triple-negative breast cancer (TNBC) alone or with another medication called pembrolizumab (MK-3475). TNBC is a type of breast cancer that doesn't have three common receptors found in other breast cancers, which makes it harder to treat. The study wants to know if patients live longer without the cancer spreading compared to standard chemotherapy treatment.
- Participants may receive Sac-TMT alone or with pembrolizumab.
- To join, participants cannot have had certain treatments before.
- There are specific health criteria to meet before participating.
Key Points: The study might involve trying new treatments, which could have unknown benefits and risks. Participants need to meet specific health criteria to join. The study will help researchers learn more about treating TNBC.
