Clinical trial for Breast Neoplasms
Official title A Clinical Study of Sacituzumab Tirumotecan (Sac-TMT, MK-2870) in People With Breast Cancer (MK-2870-032)
ClinicalTrials.gov ID: NCT06966700
What this study is testing
What is Sacituzumab tirumotecan?
An investigational intravenous infusion being studied as a potential treatment for high‑risk, early‑stage breast cancers such as triple‑negative and hormone‑receptor low/ HER2‑negative types. is designed to target cancer cells that express the Trop-2 protein, delivering a chemotherapy payload directly to those cells.
Also referred to as Sac-TMT, MK-2870.
Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.
- What it's testing
- The study wants to see if adding sacituzumab tirumotecan reduces the amount of cancer left after surgery and improves how long patients stay cancer‑free.
- Who it's for
- Adults with early‑stage, high‑risk triple‑negative breast cancer or hormone‑receptor low‑positive/HER2‑negative breast cancer.
- What's involved
- Participants receive sacituzumab tirumotecan, pembrolizumab, and standard chemotherapy, then have surgery to remove the tumor and nearby lymph nodes. They will also have regular blood tests and imaging to monitor the cancer.
- Time commitment
- The study lasts about two years, with frequent clinic visits for treatment, surgery, and follow‑up monitoring.
- Phase 3: a large, late-stage study
A plain-language read of the study's public ClinicalTrials.gov listing. The study team confirms the details.
