Optune Device - TT Field Plus Nivolumab and Ipilimumab for Melanoma With Brain Metastasis

Inclusion Criteria: * Histologically or cytologically confirmed melanoma with metastasis to the brain. * Measurable disease defined as lesions that can be accurately measured in at least one dimension (longest diameter to be recorded) as ≥ 10 mm with CT scan or MRI, as ≥ 20 mm by chest x-ray, or ≥ 10 mm with calipers by clinical exam. * Candidate for treatment with immunotherapy. * At least 18 years of age. * Normal bone marrow and organ function as defined below: * Absolute neutrophil count ≥ 1,500/mcl * Platelets ≥ 100,000/mcl * Total bilirubin ≤ 1.5 x IULN * AST(SGOT)/ALT(SGPT) ≤ 3.0 x IULN * Creatinine ≤ IULN OR creatinine clearance ≥ 60 mL/min/1.73 m2 for patients with creatinine levels above institutional normal * Women of childbearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control, abstinence) prior to study entry and for the duration of study participation, including at least 5 months (for women of childbearing potential) and at least 7 months (for men) after last dose of study drug. Should a woman become pregnant or suspect she is pregnant while participating in this study, she must inform her treating physician immediately. * Ability to understand and willingness to sign an IRB approved written informed consent document (or that of legally authorized representative, if applicable). Exclusion Criteria: * Received treatment in the metastatic setting * Treated with whole brain radiation Receiving targeted therapy or on immunosuppressive agents (dexamethasone\> 4mg/day) within 1 week of therapy. * A history of other malignancy ≤ 5 years previous with the exception of basal cell or squamous cell carcinoma of the skin which were treated with local resection only or carcinoma in situ of the cervix. * Currently receiving any other investigational agents. * A history of allergic reactions attributed to compounds of similar chemical or biologic composition to nivolumab, ipilimumab, or other agents used in the study. * Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, or cardiac arrhythmia. * History of pre-existing immunodeficiency disorder or autoimmune condition requiring immunosuppressive therapy. This includes inflammatory bowel disease, ulcerative colitis, Crohn's disease, systemic vasculitis, scleroderma, psoriasis, multiple sclerosis, hemolytic anemia, immune-mediated thrombocytopenia, rheumatoid arthritis, systemic lupus erythematosus, Sjögren's syndrome, sarcoidosis, or other rheumatologic disease or any other medical condition or use of medication which might make it difficult for the patient to complete the full course of treatments or to generate an immune response to vaccines. * Known sensitivity to conductive hydrogels. * Skull defects such as missing bone or bullet fragments. * Implanted pacemaker, programmable shunts, defibrillator, deep brain stimulator, vagus nerve stimulator, and other implanted electronic devices in the brain or spinal cord. * Pregnant and/or breastfeeding. Women of childbearing potential must have a negative pregnancy test within 14 days of study entry. * Known HIV-positivity on combination antiretroviral therapy because of the potential for pharmacokinetic interactions with nivolumab and/or ipilimumab. In addition, these patients are at increased risk of lethal infections when treated with marrow-suppressive therapy. Appropriate studies will be undertaken in patients receiving combination antiretroviral therapy when indicated.
