About this trial
The purpose of this study is to determine if a combination of two drugs sacituzumab govitecan and atezolizumab works as a treatment for residual cancer in the breast or lymph nodes and have circulating tumor DNA in the blood.
This research study involves the following investigational drugs:
* Sacituzumab govitecan * Atezolizumab
Eligibility criteria
Qualifiers
Pathologically confirmed residual invasive breast cancer, in the breast and/or lymph node(s), following neoadjuvant chemotherapy. In the absence of residual invasive disease in the breast, lymph node must contain at least 2mm of invasive disease.
In situ hybridization non-amplified (ratio of HER2 to CEP17 < 2.0 or single probe average HER2 gene copy number < 4 signals/cell), OR
Immunohistochemistry (IHC) 0 or IHC 1+.
NOTE: If more than one test result is available and not all results meet the inclusion criterion definition, all results should be discussed with the Principal Investigator to establish eligibility
Disqualifiers
Prior therapy with sacituzumab govitecan, irinotecan, or any topoisomerase I-containing antibody-drug conjugates at any time for early stage disease.
Receipt of adjuvant chemotherapy (all chemotherapy prior to registration must have occurred in the preoperative setting)
Prior hypersensitivity to atezolizumab or the excipients of atezolizumab or sacituzumab govitecan
Clinical or radiographic evidence of metastatic disease
