Brief Summary
This phase I/II trial studies the best dose of pembrolizumab and binimetinib and how well it works when given together with pembrolizumab in treating patients with triple negative breast cancer that has spread to other parts of the body (metastatic). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Binimetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving pembrolizumab and binimetinib may work better in treating patients with triple negative breast cancer.

Conditions
Outcome Measures
Primary Outcomes (2)
Maximum Tolerated Dose (MTD) of Pembrolizumab in Combination With Binimetinib Using the Standard 3+3 Design (Phase I)
Will be assessed by Common Terminology Criteria for Adverse Events version 4.0. Safety/adverse events data will be tabulated, including adverse events of all grades.
35 days
Objective Response Rate (ORR) as (Phase II)
Will be assessed by Response Evaluation Criteria in Solid Tumors (RECIST). Will utilize Simon's Two-Stage Optimal Design to test the null hypothesis. Will be estimated using the approach of Jung and Kim. The 90% lower confidence bound will be calculated using the approach of Koyama and Chen. Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.
3 years
Secondary Outcomes (3)
ORR by Immune-related RECIST Criteria (irRECIST)
Up to 3 years
Progression Free Survival (PFS)
The time from study enrollment to date of progression, assessed up to 3 years
Overall Survival (OS)
The time from study enrollment to death attributable to any cause, assessed up to 3 years
Study Arms (1)
Treatment (binimetinib, pembrolizumab)
EXPERIMENTALPatients receive binimetinib PO BID on days 1-14 of cycle 1 and on days 1-21 of cycle 2 and subsequent cycles. Beginning cycle 2, patients also receive pembrolizumab IV over 30 minutes on day 1. Cycle 1 equals 14 days. Cycles 2 and beyond repeat every 21 days in the absence of disease progression or unacceptable toxicity.

- Dual-probe HER2/CEP17 ratio \< 2.0 with an average HER2 copy number \< 4.0 signals/cell
- For phase II part of the trial: =\< 3 prior lines of treatment in the metastatic setting for the current breast cancer; however, there is no limit on number of prior line of therapy in phase I part of the trial
- Measurable disease
- Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 or 1
- Hemoglobin \>= 9.0 g/dL (must be \>= 7 days after most recent transfusion) (obtained =\< 14 days prior to registration)
- Absolute neutrophil count (ANC) \>= 1500/mm\^3 or \>= 1.5 x 10\^9/L (obtained =\< 14 days prior to registration)
- +30 more criteria
You may not qualify if:
- Any of the following because this study involves an investigational agent whose genotoxic, mutagenic and teratogenic effects on the developing fetus and newborn are unknown:
- Pregnant women
- Nursing women
- Men or women of childbearing potential who are unwilling to employ adequate contraception
- Receiving any other investigational agent which would be considered as a treatment for the primary neoplasm OR participated in a study of an investigational agent, received study therapy or used an investigational device =\< 4 weeks prior to registration
- Immunocompromised patients and patients with known immunodeficiency; or receiving systemic steroid therapy or any other immunosuppressive therapy =\< 7 days prior to registration; NOTE: inhaled steroids and low-dose corticosteroids are allowed
- History of active tuberculosis (TB), human immunodeficiency virus (HIV), active hepatitis B (e.g., hepatitis B surface antigen \[HBsAg\] reactive) and/or active hepatitis C infection (e.g. hepatitis C virus \[HCV\] ribonucleic acid \[RNA\] qualitative is detected)
- Received a live vaccine =\< 30 days prior to registration; NOTE: seasonal influenza vaccines for injection are generally inactivated flu vaccines and are allowed; however intranasal influenza vaccines (e.g., FluMist) are live attenuated vaccines, and are not allowed

- Any active central nervous system (CNS) lesion (i.e., those with radiographically unstable, symptomatic lesions) and/or leptomeningeal metastases; NOTE: patients treated with stereotactic radiotherapy or surgery are eligible if no evidence of CNS disease progression \>= 4 weeks and patients must be off corticosteroid therapy for \>= 3 weeks; NOTE: carcinomatous meningitis is excluded regardless of clinical stability
- Active autoimmune disease requiring systemic treatment in the past 2 years (i.e. use of disease modifying agents, corticosteroids or immunosuppressive drugs); NOTE: replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) is not considered a form of systemic treatment
