简要总结
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
详细描述
This is an open label single-arm phase II study to evaluate the combination therapy of the antibody drug conjugate, sacituzumab govitecan, and the anti-PD-L1 antibody, atezolizumab, in patients with triple negative breast cancer.
The research study procedures include screening for eligibility and study treatment including laboratory evaluations, stool collection and follow up visits.
This research study involves the following investigational drugs:
- Sacituzumab govitecan
- Atezolizumab
Participants will receive study treatment for 18 weeks and will be followed for every 6 months for 3 years.

入选标准
- •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.
- •HER2 negative in primary tumor pre-treatment by local pathology assessed according to current ASCO/CAP guidelines:
- •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
- •ER and PR negative in primary tumor pre-treatment defined as < 10% of cells expressing hormonal receptors via IHC analysis by local laboratory assessment.
- •Patients must have received neoadjuvant chemotherapy prior to breast surgery.
- •Patients must be within 4 months of completion of all locoregional therapy (either last surgery or last dose of radiation, whichever is later) . Definitive breast surgery must have been performed and includes lumpectomy or mastectomy with pathologically clear margins (i.e. no ink on tumor). For patients undergoing lumpectomy, this must be followed by whole breast irradiation. Definitive surgery also includes axillary surgery, either sentinel lymph node biopsy or axillary lymph node dissection at the discretion of the attending surgeon.
- •Evidence of ctDNA in blood sample collected after completion of all local and systemic neoadjuvant therapy (preoperative chemotherapy, surgery and radiation), confirmed by central testing. Detection of any tumor specific mutations (TSMs) within the sample will be considered positive for purposes of study eligibility.

- •Serum creatinine < 1.5 x institutional ULN
- •Creatinine clearance ≥30 mL/min as assessed by the Cockcroft-Gault equation
- •Serum albumin ≥ 25 g/L (2.5 g/dL)
- •For patients not receiving therapeutic anticoagulation: INR or aPTT ≤ 1.5 × institutional ULN
- •For patients receiving therapeutic anticoagulation: stable anticoagulant regimen
- •Women of childbearing potential (pre-menopausal) must have a negative serum or urine pregnancy test within 7 days prior to start of therapy. A woman is defined as premenopausal if she is less than 12 months from last menstrual period with no identified cause other than menopause (medication induced amenorrhea is not acceptable). Pregnancy test is not required in women who are surgically sterile via bilateral salpingooophorectomy or hysterectomy.
- •Women of childbearing potential and men must agree to use adequate contraception for the duration of protocol treatment and for 6 months after last dose of atezolizumab and 6 months after last dose of sacituzumab govitecan, whichever is later. Hormonal contraceptives are not acceptable (see section 5.6).
- •Ability to understand and the willingness to sign a written informed consent document. Non-English speakers are eligible to participate but will be excluded from surveys/questionnaires unless the participant has a proxy available for translation.
