I. To evaluate the intracranial objective response rate (ORR) (complete response [CR] or partial response [PR] by Response Assessment in Neuro-Oncology Brain Metastases [RANO-BM]) with sacituzumab govitecan (IMMU-132) in patients with HER2-negative metastatic breast cancer with brain involvement.
I. To evaluate bi-compartmental progression-free survival in this population. II. To evaluate overall survival in this population. III. To assess safety and tolerability of sacituzumab govitecan (IMMU-132) treatment in this population.
IV. To evaluate ORR by hormone-receptor (HR) subgroup (HR+, HR-).
I. To bank specimens for future correlative studies.
Patients receive sacituzumab govitecan intravenously (IV) over 1-3 hours on days 1 and 8. Cycles repeat every 21 days for up to 2 years in the absence of disease progression or unacceptable toxicity.
After completion of study registration, patients are followed up every 3 months for 1 year and then every 6 months for 1 year.

Experimental: Treatment (sacituzumab govitecan)
Patients receive sacituzumab govitecan IV over 1-3 hours on days 1 and 8. Cycles repeat every 21 days for up to 2 years in the absence of disease progression or unacceptable toxicity.
Biological: Sacituzumab Govitecan
- Objective response rate (ORR) [ Time Frame: Up to 2 years ]ORR will be evaluated using use a Simon two-stage minimax design.
- Overall survival [ Time Frame: From date of registration to date of death due to any cause, assessed up to 2 years ]Will use the Kaplan-Meier curves to estimate the respective survival curves.
- Progression-free survival [ Time Frame: From date of registration to date of first documentation of progression or symptomatic deterioration or death due to any cause, assessed up to 2 years ]Will use the Kaplan-Meier curves to estimate the respective survival curves.
- Incidence of adverse events [ Time Frame: Up to 2 years ]Adverse events will be graded using the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0. The incidence of adverse events will be reported. Toxicity will be by grade and attribution to treatment.
