Brief Summary
This early phase I trial studies the side effects and feasibility of cryoablation, atezolizumab, and nab-paclitaxel in treating patients with triple negative breast cancer that has spread to nearby tissue or lymph nodes (locally advanced) or has spread to other places in the body (metastatic). Cryosurgery, also known as cryoablation or cryotherapy, kills tumor cells by freezing them. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Drugs used in chemotherapy, such as nab-paclitaxel, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving cryoablation, atezolizumab and nab-paclitaxel may improve response to the disease.

Outcome Measures
Primary Outcomes (1)
Safety and Feasibility of cryoablation with systemic atezolizumab/nab-paclitaxel
All adverse events will be reported by grade using frequencies and relative frequencies, and rates will be estimated using a 90% confidence interval obtained using Jeffrey's prior method.
5 years
Secondary Outcomes (5)
Abscopal response in the distant non-cryoablated site(s)
5 years
Systemic effector cell and cytokine responses
At baseline, after cryoablation, and after atezolizumab and nab-paclitaxel
Overall survival
Assessed up to 5 years
Disease-specific survival
Time from cryoablation until death due to breast cancer or last follow-up, assessed up to 5 years
Progression-free survival
Time from cryoablation to tumor growth as defined by modified Response Evaluation Criteria in Solid Tumors (RECIST) criteria, assessed up to 5 years
Study Arms (1)
Treatment (cryoablation, atezolizumab, nab-paclitaxel)
EXPERIMENTALPatients undergo cryoablation of the primary tumor over about 1 hour. After 2-3 weeks, patients receive atezolizumab IV on days 1 and 15 and nab-paclitaxel IV on days 1, 8, and 15. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Interventions
Given IV
Undergo cryoablation of the primary tumor

Eligibility Criteria
You may qualify if:
- Locally advanced or metastatic PD-L1 positive TNBC (TNBC is defined as estrogen receptor \[ER\] \< 10%, progesterone receptor \[PR\] \< 10%, and HER2 non-amplified; and PD-L1 positive is defined as \>= 1%.)
- Presents with primary breast tumor lesion amenable to cryoablation
- Have at least one additional distant lesion feasible for biopsies
- Agreeable to start on atezolizumab and nab-paclitaxel as per standard of care
- Patients with locally advanced disease must be ineligible for curative surgery for any reason, including but not limited to comorbid status precluding surgery due to safety, unresectability, or patient refusal
- Patient may have received prior systemic chemotherapy regimens
You may not qualify if:
- History of autoimmune disease
- History of human immunodeficiency virus (HIV)
- Previous immune checkpoint targeting therapies
- No primary breast lesion amenable for cryoablation due to size (greater than 5 cm) or location (proximity of \< 0.5 cm to the skin or nipple-areola complex)
- Pregnancy
