Brief summary

This phase II trial studies the side effects and how well white blood cells taken from person's own (autologous) cluster of differentiation (CD)8+ antigen-specific T cells, cyclophosphamide, aldesleukin, and ipilimumab work in treating patients with melanoma that has spread to another place in the body. Autologous CD8+ antigen-specific T cells are white blood cells that are designed in the laboratory to find melanoma cells and may kill them. Biological therapies, such as aldesleukin, use substances made from living organisms that may stimulate the immune system in different ways and stop tumor cells from growing. Immunotherapy with monoclonal antibodies, such as ipilimumab, 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 cyclophosphamide, 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 autologous CD8+ antigen-specific T cells with cyclophosphamide, aldesleukin, and ipilimumab may be an effective treatment for patients with metastatic melanoma.

Detailed description

PRIMARY OBJECTIVE: I. Evaluate the safety and efficacy of adoptively transferred cytotoxic T-lymphocytes (CTL) targeting melanoma tumors combined with anti-CTLA4. SECONDARY OBJECTIVES: I. Evaluate the influence of anti-CTLA4 on the duration of in vivo persistence and anti-tumor efficacy achieved following adoptive transfer of antigen-specific CTL. II. Evaluate the influence of anti-CTLA4 on the induction of T cells to non-targeted tumor-associated antigens (antigen-spreading) following adoptive transfer antigen-specific CTL, and the correlation of these responses with clinical outcome. OUTLINE: Beginning 48 to 72 hours prior to T cell infusion, patients receive cyclophosphamide intravenously (IV) over 30-60 minutes. Patients then receive autologous CD8+ melanoma-specific T cells IV over 30-60 minutes on day 0, aldesleukin subcutaneously (SC) twice daily (BID) on days 0-13 and ipilimumab IV over 90 minutes on days 1, 22, 43, and 64 in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up every 3 months for up to 5 years.

Exclusion criteria

* EXCLUSION FOR ENROLLMENT * Any other malignancy from which the patient has been disease-free for less than 5 years, with the exception of adequately treated and cured basal or squamous cell skin cancer, superficial bladder cancer, carcinoma in situ of the cervix * Pregnant women, nursing mothers, men or women of reproductive ability who are unwilling to use effective contraception; women of childbearing potential with a positive pregnancy test within 3 days prior to entry * Active and untreated central nervous system (CNS) metastasis (including metastasis identified during screening magnetic resonance imaging \[MRI\] or contrast computed tomography \[CT\]) * No signs or symptoms of CNS metastases (mets) within the last 30 days (from enrollment evaluation) * No single lesion larger than 1 cm * No more than 5 lesions * Autoimmune disease: patients with a history of inflammatory bowel disease are excluded from this study, as are patients with a history of autoimmune disease (e.g. systemic lupus erythematosus, vasculitis, infiltrating lung disease) whose possible progression during treatment would be considered by the investigator to be unacceptable * Any underlying medical or psychiatric condition, which in the opinion of the investigator, will make the administration of study drug hazardous or obscure the interpretation of adverse events, such as a condition associated with frequent diarrhea * Positive screening tests for human immunodeficiency virus (HIV), hepatitis B (hep B), and hepatitis C (hep C) (referencing blood draw at leukapheresis screening); if positive results are not indicative of true active or chronic infection, the patient can be treated * White blood cells (WBC) =\< 1000/uL * Hematocrit (Hct) =\< 24% or hemoglobin (Hb) =\< 8 g/dL * Absolute neutrophil count (ANC) =\< 500 * Platelets =\< 50,000 * Creatinine \>= 3.0 x upper limit of normal (ULN) * Aspartate aminotransferase (AST)/alanine aminotransferase (ALT) \>= 2.5 x ULN * Bilirubin \>= 3 x ULN * Steroids are not permitted 3 days prior to T cell infusion and concurrently during therapy * Any non-oncology vaccine therapy used for the prevention of infectious disease within 1 month before or after any ipilimumab dose * Patients may not be on any other treatments for their cancer aside from those included in the protocol; patients may not undergo another form of treatment concurrently with this study *
