This research study is studying to evaluate sacituzumab govitecan for individuals with localized triple negative breast cancer (TNBC)
The names of the study drugs involved in this study is:
- Sacituzumab govitecan (SG)
- Pembrolizumab (combination therapy with SG)

Invasive Breast Cancer Triple Negative Breast Cancer ER-Negative Breast Cancer PR-Negative Breast Cancer HER2-negative Breast Cancer | Drug: Sacituzumab Govitecan Drug: Pembrolizumab | Phase 2 |
This research study is a Phase II clinical trial. Phase II clinical trials test the safety and effectiveness of an investigational drug to learn whether the drug works in treating a specific disease. "Investigational" means that the drug is being studied.
This research study involves an experimental study treatment. The names of the study drugs involved in this study is:
- Sacituzumab govitecan (SG)
- Pembrolizumab (combination therapy with SG)
The study is a umbrella study multi-arm phase II study of neoadjuvant SG-based therapy in patients with localized BC. The first cohort involves SG monotherapy. After the monotherapy cohort completes enrollment, the combination therapy cohort (SG with pembrolizumab) for patients with localized BC will open.
Future planned arms include SG with/without pembrolizumab for patients with Hormone Receptor positive (HR+) breast cancer and inflammatory breast cancer (IBC).
The research study procedures include screening for eligibility and study treatment including evaluations and follow up visits.
- Eligible participants will receive Sacituzumab govitecan for up to 12 weeks.
- This can be followed by standard chemotherapy at the discretion of the treating physician.
- It is expected that about 50 people will take part in this research study.
The U.S. Food and Drug Administration (FDA) has not approved Sacituzumab govitecan as a treatment for patients with metastatic TNBC.
Sacituzumab govitecan (SG) is an antibody-drug conjugate which means it's made up of an antibody attached to an anticancer drug. An antibody is a protein normally made the immune system. Sacituzumab govitecan is believed to work by binding the antibody portion of the drug in the tumor(s) while the anticancer drug portion works to prevent cancer cells from growing/spreading.
After the SG monotherapy cohort completes enrollment, the combination therapy cohort (SG with immunotherapy) will open.

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Female or male patients ≥ 18 years of age.
- Histologically confirmed diagnosis of invasive breast cancer, previously untreated.
- Participants must have biopsy proven ER negative (ER-), PR negative (PR-), HER2 negative (HER2-), invasive breast cancer. ER, PR, and HER2 positivity would be determined per ASCO/CAP guidelines by institutional (local) assessment. Patients with multi-focal and multicentric disease are eligible provided all histologically examined lesions are ER-/PR-/HER2- (local assessment). The need to biopsy additional lesions is at the discretion of the treating physician. Patients with bilateral invasive breast cancer are eligible provided all histologically examined lesions are ER-/PR-/HER2- (local assessment).
- Primary tumor (at least one lesion) 1 cm or greater measured by radiological imaging. Regional lymph node AJCC (v7) TNM stages N0-N2. If node positive, any primary tumor size is permissible. Absence of distant metastatic disease (AJCC TNM stage M0). Staging scans are not required and are per discretion of the treating physician.
- Pre- and postmenopausal women are eligible.
- ECOG performance status = 0, 1 (Karnofsky ≥60%, see Appendix A)
- Ability to understand and the willingness to sign a written informed consent form (ICF). Patient has signed the ICF prior to any screening procedures being performed and is able to comply with protocol requirements, including research biopsy.
- Patient has adequate bone marrow and organ function as defined by the following laboratory values at screening:
- Absolute neutrophil count (ANC) ≥ 1,500 per mm3
- Platelets ≥ 100,000 per mm3

- Uncorrected hypomagnesemia or hypokalemia.
- Systolic Blood Pressure (SBP) >160 mmHg or <90 mmHg.
