Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This phase Ib/II trial tests the safety, best dose and how well gemcitabine and ex vivo expanded allogenic universal donor TGFBi NK cells with or without naxitamab work for the treatment of patients with GD2 expressing, HER2 negative breast cancer that has spread from where it first started (primary site) to other places in the body (metastatic). Gemcitabine is a chemotherapy drug that blocks the cells from making deoxyribonucleic acid (DNA) and may kill cancer cells. TGFBi NK cells are manufactured cells that are a part of your natural immunity. NK cells can recognize missing or incorrect proteins on tumor cells and then eliminate these tumor cells and TGFBi NK cells are created to be able to better kill the tumor cells. Naxitamab is a monoclonal antibody that targets GD2, which is a protein or sugar present on tumor cells but not very commonly found on normal cells. This antibody helps draw the attention of the immune system to the tumor cells that have GD2 to help attack the tumor cells. Giving gemcitabine and TGFBi NK cells with or without naxitamab may kill more tumor cells in patients with metastatic GD2 expressing, HER2 negative breast cancer.

Gilbert's syndrome will be defined as elevated unconjugated bilirubin, with conjugated (direct) bilirubin within the normal range and less than 20% of the total. Total bilirubin will be permitted up to 5 mg/dL, if patients have historical readings consistent with the definition of Gilbert's syndrome prior to entering study. Adequate hepatic function for patients with known liver metastases is defined as AST and ALT levels ≤ 5 X ULN
* The effects of the trial agents on the developing human fetus are unknown. However, gemcitabine is known to have negative fetal effects. For this reason: Women of childbearing potential must agree to use adequate contraception at study entry, for the duration of study participation and for 7 months after the last dose of study medication based upon estimated half-life or receptor occupancy. Adequate contraception is defined as 2 highly effective methods of contraception (including a physical barrier). Should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, she should inform her treating physician immediately. Men should refrain from fathering a child using adequate contraception or donating sperm during the study and for 6 months after the last dose of study medications. Adequate contraception is defined as 2 highly effective methods of contraception (including a physical barrier)
* Patients with well-controlled human immunodeficiency virus (HIV) infection are eligible for trial as long as:

* On an effective anti-retroviral therapy (ART) ˃ 4 weeks and with evidence of viral-suppression as defined as HIV viral load ˂ 400 copies/mL within the last 3 months
* CD4 \> 200 cells/µL within the last 3 months; and
* No reported opportunistic infections within 6 months prior to enrollment, except for the following which will be allowed:

* Esophageal candidiasis treated within last 6 months or currently improving with antifungal treatment.
* Oral and/or genital herpes simplex virus (HSV) treated within last 6 months or currently improving with antiviral treatment.
* Mycobacterium avium infection in last 6 months or that has been treated for at least 1 month
* Patients with evidence of chronic hepatitis B virus (HBV) infection are eligible for trial as long as the HBV viral load is undetectable on suppressive therapy, if indicated.

* Patients with history of hepatitis C virus (HCV) infection must have been treated and cured. For patients with HCV infection who are currently on treatment, they are eligible if they have an undetectable or unquantifiable HCV ribonucleic acid (RNA) 12 weeks or longer after definitive treatment completion.
* Patients must be able to understand and willing to sign a written informed consent document
* Any adverse events subjects have experienced from prior therapy must have resolved to =\< grade 1 according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) version 5

Exclusion Criteria

* Patients who within 3 weeks prior to study enrollment who have received chemotherapy, investigational agents, or radiation
* Patients with active brain metastases or leptomeningeal metastases are excluded from this clinical trial because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events. However, patients with treated brain metastases are eligible if there is no magnetic resonance imaging (MRI) evidence of progression for 6 months after treatment is complete and within 28 days prior to the first dose of trial drug. Patients requiring immunosuppressive doses of systemic corticosteroids (\> 10mg/day prednisone equivalent) for palliation are excluded
* Patients with a history of another invasive malignancy \< 3 years prior to enrollment (patients with non-melanoma skin cancers, carcinoma in situ of the breast or cervix are eligible)
* History of allergic reactions attributed to compounds of similar chemical or biologic composition to agents used in study
* Uncontrolled intercurrent illness including, but not limited to, ongoing active infection that requires systemic treatment with ongoing antibiotics (eligible if can stop antibiotics on day of enrollment), unexplained fever (temperature \> 38.1˚celcius \[C\]) within 7 days of initial treatment, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situation that in the opinion of the primary investigator would prohibit the patient from complying with study requirements
* Patients with bone metastases who have initiated denosumab or a bisphosphonate therapy within 28 days prior to or after cycle 1 day 1 due to the potential for flu-like symptoms and mild cytokine release syndrome with the initial dose. However, continuation of prior therapy is allowed
* Patients should have no evidence of being immunocompromised as listed below:

* Active, known or suspected autoimmune disease. Patients are permitted to enroll if they have vitiligo, type I diabetes mellitus, residual hypothyroidism due to an autoimmune condition only requiring hormone replacement, psoriasis not requiring systemic treatment or conditions not expected to recur in the absence of an external trigger in the opinion of the primary investigator
* Altered immune function that in the judgement of the PI that may affect a patient's ability to adequately engage the immune system and respond to the immunotherapy agents being administered, including but not limited to: inflammatory bowel disease; active infectious enteritis; eosinophilic enteritis; lupus erythematous; ankylosing spondylitis; scleroderma; multiple sclerosis. These criteria do not include all disease with an immune-related component but are not autoimmune in nature or have a primary alteration in the general immune function that may interfere with the vaccine mechanism of action, for example celiac disease
* Immunosuppressive therapy post-organ transplant
* Pregnant and breastfeeding women are excluded from this study because of the potential for teratogenic or abortifacient effects with all of the agents involved in this trial. Females of childbearing potential who are pregnant, breast feeding, intend to become pregnant, or are not using adequate contraceptive methods or males who are not using adequate contraceptive methods. Women of childbearing potential must agree to use two methods of adequate contraception at study entry be used for the duration of study participation and for at least 7 months for women and 6 months for men after the final dose of any study-related medications
* Clinically significant cardiomyopathy, coronary disease, myocardial infarction, chronic heart failure (CHF) (New York Heart Association class III or IV or hospitalization for CHF), ejection fraction \< 50% or cerebrovascular accident within 6 months prior to enrollment
* Patients with a history of myocarditis are excluded due to the potential of myocarditis with anti-PD-L1 antibodies or other immunotherapies
* Patients who have received any live vaccines within 30 days prior to enrollment (inactivated vaccines including COVID vaccines are allowed)
* Any other condition, which would, in the opinion of the principal investigator the subject is a poor candidate for the clinical trial or would jeopardize the subject or the integrity of the data obtained
* Inadequate pulmonary function defined as evidence of dyspnea at rest, exercise intolerance, and/or chronic oxygen requirement. In addition, room air pulse oximetry \< 90% and/or abnormal pulmonary function tests within 28 days of C1D1 if these assessments are clinically indicated.
