Multi-epitope Folate Receptor Alpha Peptide Vaccine, GM-CSF, and Cyclophosphamide in Treating Patients with Triple Negative Breast Cancer
- Resected unilateral or bilateral primary carcinoma of the breast without clinical evidence of metastatic disease (after neoadjuvant chemotherapy and/or adjuvant chemotherapy), negative for estrogen receptor (ER) and progesterone receptor (PR) (cut-off for positivity is > 10% positive tumor cells with nuclear staining), and negative for HER2 as defined by one of the four situations delineated below: * HER2 immunohistochemistry (IHC) expression of 0 or 1+ and in-situ hybridization non-amplified * HER2 IHC expression of 0 or 1+ and in-situ hybridization not done * HER2 IHC expression of 2+ and in-situ hybridization non-amplified * IHC not done and in-situ hybridization non-amplified * Note: central review is not required * Note: If biopsy and surgical specimens are discordant from each other with regard to ER, PR, and/or HER2 status, a patient will be allowed to enroll assuming at least one of the specimens meets the above criteria and no endocrine therapy use is planned going forward
- Completed planned breast surgeries and any radiation therapy >= 60 days prior to randomization * Note: Reconstructive and prophylactic surgeries are allowed after randomization (during study treatment)
- Completed last cycle of chemotherapy (which can be given in the adjuvant and/or neoadjuvant setting) >= 90 days but not >= 365 days prior to randomization
- Patient had at least one of the following: * Biopsy or surgery-proven regional node involvement by cancer * T1c, T2, T3, or T4 disease (inflammatory disease allowed) identified at the time of surgery or clinically identified prior to neoadjuvant chemotherapy * No complete response to neoadjuvant chemotherapy (those who did achieve complete response are still eligible if a pre-chemotherapy regional nodal biopsy identified cancer or if the pre-chemotherapy tumor measured > 1 cm)
- Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0, 1
- Absolute neutrophil count (ANC) >= 1500/mm^3 obtained =< 14 days prior to randomization
- Platelet count >= 75,000/uL obtained =< 14 days prior to randomization
- Aspartate transaminase (AST) =< 3 x upper limit of normal (ULN) obtained =< 14 days prior to randomization
- Creatinine =< 1.5 x ULN obtained =< 14 days prior to randomization
- Urine dipstick proteinuria < 2+ or urine protein/creatinine (UPC) ratio =< 1.0 obtained =< 14 days prior to randomization; Note: patients discovered to have >= 2+ proteinuria on dipstick urinalysis at baseline should undergo a 24-hour urine collection and must demonstrate =< 1 g of protein in 24 hours
- Negative serum pregnancy test done =< 14 days prior to randomization, for women of childbearing potential only
- Provide informed written consent
- Willing to return to enrolling institution for follow-up
- Willing to provide tissue and blood samples for correlative research studies
- Any of the following: * Pregnant women * Nursing women * Women of childbearing potential who are unwilling to employ adequate contraception
- Clinical evidence of local recurrence or distant metastases; Note: New primary tumors are allowed, both contralaterally and ipsilaterally, but a prior breast cancer must have been more than 5 years beforehand
- Known hypersensitivity reaction to GM-CSF
- Active autoimmune disease that has required systemic treatment =< 30 days (i.e., with use of disease modifying agents, corticosteroids, or immunosuppressive drugs) prior to randomization; Note: replacement therapy (e.g., thyroxine, insulin, or physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency) is not considered a form of systemic treatment; patients with vitiligo, Graves disease, or psoriasis not requiring systemic treatment within the past 30 days are not excluded; patients with Celiac disease controlled with diet modification are not excluded
- Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
- History of other cancer < 5 years prior to consent (except non-melanoma skin cancer or carcinoma in situ of the uterine cervix) or receiving other specific treatment for this cancer (monoclonal antibody, small molecule pathway inhibitor)
- Treatment with systemic corticosteroid or immune-modulators =< 7 days prior to randomization
- Concurrent treatment with other experimental drugs or any other systemic anticancer therapy (due to unknown drug-vaccine potential interactions) * NOTE: Aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs), statins, and other medications commonly used to treat nononcologic, non-autoimmune conditions are allowed
- Immunocompromised patients and patients known to be human immunodeficiency virus (HIV) positive and currently receiving antiretroviral therapy
- Prior or concurrent use of trastuzumab
- Prior or concurrent use of a PD-1 or PD-L1 checkpoint inhibitor including pembrolizumab unless the use was >= 3 months prior to randomization

I. To show that multi-epitope folate receptor alpha peptide vaccine (folate receptor [FR]alpha peptide vaccine) with sargramostim (GM-CSF) adjuvant will prolong the disease-free survival (DFS) compared to GM-CSF adjuvant treatment in patients with triple negative breast cancer.
I. To compare the safety and tolerability of metronomic cyclophosphamide followed by FRalpha peptide vaccine with GM-CSF versus GM-CSF alone.
CORRELATIVE RESEARCH OBJECTIVES:
I. To determine whether high level of antibody and cellular immune response toward the FRalpha measured at baseline is a prognostic factor for vaccine immune response and/or cancer relapse.
II. To determine whether the level of tumor expression of FRalpha at baseline is a prognosis factor for vaccine immune response and/or cancer relapse.
OUTLINE: Patients are randomized to 1 of 2 arms.
ARM I: Patients receive cyclophosphamide orally (PO) twice daily (BID) on days 1-7 and 15-21 of cycle 1 only. Starting cycle 2, patients receive multi-epitope folate receptor alpha peptide vaccine with sargramostim intradermally (ID) on day 1. Treatment repeats every 28 days for cycles 2-7 and every 6 months for cycles 8-14 in the absence of disease progression or unacceptable toxicity.
ARM II: Patients receive cyclophosphamide as in Arm I. Starting cycle 2, patients receive placebo vaccine with sargramostim ID on day 1. Treatment repeats every 28 days for cycles 2-7 and every 6 months for cycles 8-14 in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 6 months for 3 years.
