• Patients must have measurable disease per RECIST 1.1 criteria; all sites of disease must be evaluated within 4 weeks prior to randomization
• Patients may have had prior systemic therapy in the adjuvant setting (e.g. interferon, BRAF, or MEK agents). Patients may have had prior anti-CTLA-4 in the adjuvant setting, if at least one year from last dose of treatment has passed prior to beginning treatment. Patients may have had any prior anti-PD-1 or anti-PD-L1 agent in the adjuvant setting, if at least one year from last dose of treatment has passed prior to beginning treatment
• Patients may not have had any prior ipilimumab and/or anti-PD-1/PD-L1 agent in the metastatic setting
• Patients must have discontinued chemotherapy, immunotherapy or other investigational agents used in the adjuvant setting >= 4 weeks prior to randomization and recovered from adverse events due to those agents; mitomycin and nitrosoureas must have been discontinued at least 6 weeks prior to entering the study; patients must have discontinued radiation therapy >= 2 weeks prior to entering the study and recovered from any adverse events associated with treatment; prior surgery must be >= 4 weeks from randomization and patients must be fully recovered from post-surgical complications
• Patients must not receive any other investigational agents while on study or within four weeks prior to randomization
• Patient must not have received any live vaccine within 30 days prior to randomization, while participating in the study, and for 4 weeks (28 days) after the last dose of protocol treatment; live vaccines include, but are not limited to, the following: measles, mumps, rubella, chicken pox, yellow fever, rabies, bacillus Calmette-Guerin (BCG), and typhoid (oral) vaccine; patients are permitted to receive inactivated vaccines and any non-live vaccines including those for the seasonal influenza and coronavirus disease 19 (COVID-19) (Note: intranasal influenza vaccines, such as Flu-Mist (registered trademark) are live attenuated vaccines and are not allowed); if possible, it is recommended to separate study drug administration from vaccine administration by about a week (primarily, in order to minimize an overlap of adverse events)
• Patients are ineligible if they have any currently active central nervous system (CNS) metastases; patients who have treated brain metastases (with either surgical resection or stereotactic radiosurgery) that have been stable on head magnetic resonance imaging (MRI) or contrast computed tomography (CT) scan for at least 4 weeks following treatment and within 4 weeks prior to randomization are eligible; patients must not have taken any steroids =< 14 days prior to randomization for the purpose of managing their brain metastases; patients with only whole brain irradiation for treatment of CNS metastases will be ineligible
• Patients must not have other current malignancies, other than basal cell skin cancer, squamous cell skin cancer, in situ cervical cancer, ductal or lobular carcinoma in situ of the breast; patients with other malignancies are eligible if they have been continuously disease-free for > 3 years prior to the time of randomization
• White blood count >= 3,000/uL (obtained within 4 weeks prior to randomization)
• Absolute neutrophil count (ANC) >= 1,500/uL (obtained within 4 weeks prior to randomization)
• Platelet count >= 100,000/uL (obtained within 4 weeks prior to randomization)
• Hemoglobin >= 9 g/dL (obtained within 4 weeks prior to randomization)
• Serum creatinine =< 1.5 x upper limit of normal (ULN) or serum creatinine clearance (CrCl) >= 40 ml/min (obtained within 4 weeks prior to randomization)
• Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) =< 3 x ULN (=< 5 x ULN for patients with documented liver metastases) (obtained within 4 weeks prior to randomization)
• Alkaline phosphatase =< 2 x ULN (=< 5 x ULN for patients with known liver involvement and =< 7 x ULN for patients with known bone involvement) (obtained within 4 weeks prior to randomization)
• Total bilirubin =< 1.5 x ULN except patients with normal direct bilirubin; those patients with known Gilbert’s syndrome must have total bilirubin < 3 x ULN (obtained within 4 weeks prior to randomization)
• Serum lactate dehydrogenase (LDH) =< 10 X ULN (obtained within 4 weeks prior to randomization)
• Patients must not have any serious or unstable pre-existing medical conditions (aside from malignancy exceptions specified above), including but not limited to, ongoing or active infection requiring parenteral antibiotics on day 1, history of bleeding diathesis or need for concurrent anticoagulation (international normalized ratio [INR] =< 1.5 and partial thromboplastin time [PTT] within 1.1 x ULN), or psychiatric illness/social situations that would limit compliance with study requirements, interfere with patient's safety, or obtaining informed consent
• Patients with human immunodeficiency virus (HIV) infection are ineligible; due to the mechanism of action of ipilimumab and GM-CSF, activity and side effects in an immune compromised patient are unknown
• Patients with evidence of active hepatitis B virus (HBV) or hepatitis C virus (HCV) infection are not eligible; patients with cleared HBV and HCV (0 viral load) infection will be allowed
• Patients must not have autoimmune disorders or conditions of immunosuppression that require current ongoing treatment with systemic corticosteroids (or other systemic immunosuppressants), including oral steroids (e.g., prednisone, dexamethasone) or continuous use of topical steroid creams or ointments or ophthalmologic steroids; a history of occasional (but not continuous) use of steroid inhalers is allowed; replacement doses of steroids for patients with adrenal insufficiency are allowed; patients who discontinue use of these classes of medication for at least 2 weeks prior to randomization are eligible if, in the judgment of the treating physician investigator, the patient is not likely to require resumption of treatment with these classes of drugs during the study
• Exclusion from this study also includes patients with a history of symptomatic autoimmune disease (e.g., rheumatoid arthritis, systemic progressive sclerosis [scleroderma], systemic lupus erythematosus, Sjogren's syndrome, autoimmune vasculitis [e.g., Wegener’s granulomatosis]); motor neuropathy considered of autoimmune origin (e.g., Guillain-Barre syndrome and myasthenia gravis); other CNS autoimmune disease (e.g., multiple sclerosis)
• Patients with autoimmune hypothyroid disease or type I diabetes on replacement treatment are eligible
• Patients must not have a history of inflammatory bowel disease or diverticulitis (history of diverticulosis is allowed)
• Patients must not have other significant medical, surgical, or psychiatric conditions or require any medication or treatment that in the opinion of the investigator may interfere with compliance, make the administration of the study drugs hazardous or obscure the interpretation of adverse events (AEs), such as a condition associated with frequent diarrhea; patients must not have an active infection requiring current treatment with parenteral antibiotics
