Sacituzumab Govitecan +/- Pembrolizumab in Metastatic TNBC
Trial Parameters
Brief Summary
This research study involves testing the safety and efficacy of an investigational intervention for patients with triple-negative breast cancer (TNBC) that has spread, or metastasized, to other parts the body and is PD-L1-negative. The names of the study interventions involved in this study are: * Sacituzumab govitecan (Trodelvy™;IMMU-132) * Pembrolizumab (Keytruda®; MK-3475)
Eligibility Criteria
Inclusion Criteria: * Participants must have histologically or cytologically confirmed invasive breast cancer with unresectable locally advanced or metastatic disease. Participants without pathologic or cytologic confirmation of metastatic disease should have unequivocal evidence of metastasis from physical examination or radiologic evaluation. * Estrogen-receptor and progesterone-receptor expression both ≤ 5% by immunohistochemistry (IHC), and HER2-negative status as determined by the current ASCO/CAP guidelines. If a patient has more than one histological result, the most recent sample will be considered for inclusion. * Participants must have PD-L1-negative metastatic breast cancer defined as less than 1% expression of PD-L1 on tumor-infiltrating immune cells (IC) by the PD-L1 IHC SP142 assay or a Combined Positive Score (CPS) less than 10 by the PD-L1 IHC 22C3 assay measured with standard of care testing. * Participants must be treatment-naïve in the metastatic setting. * Participa
