Normal cardiac function; patients who have a history of heart disease, or who are over the age of 50 years must have a normal cardiac stress test within the prior 90 days
Normal lung function; patients who have extensive pulmonary metastases or any chronic pulmonary disease history must have pulmonary function testing demonstrating forced expiratory volume in 1 second (FEV1) and forced vital capacity (FVC) > 65% of predicted values
Absolute neutrophil count (ANC) >= 1,500 /mcL
Platelets >= 100,000 / mcL
Hemoglobin >= 9 g/dL or >= 5.6 mmol/L without transfusion or erythropoietin (EPO) dependency (within 7 days of assessment)
Serum creatinine =< 1.5 X upper limit of normal (ULN) OR measured or calculated creatinine clearance (glomerular filtration rate [GFR] can also be used in place of creatinine or creatinine clearance [CrCl]) >= 60 mL/min for subject with creatinine levels > 1.5 X institutional ULN
Serum total bilirubin =< 1.5 X ULN OR direct bilirubin =< ULN for subjects with total bilirubin levels > 1.5 ULN
Aspartate aminotransferase (AST) (serum glutamic-oxaloacetic transaminase [SGOT]) and alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 X ULN OR =< 5 X ULN for subjects with liver metastases
Albumin >= 2.5 mg/dL
International normalized ratio (INR) or prothrombin time (PT) =< 1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or partial thromboplastin time (PTT) is within therapeutic range of intended use of anticoagulants
Activated partial thromboplastin time (aPTT) =< 1.5 X ULN unless subject is receiving anticoagulant therapy as long as PT or PTT is within therapeutic range of intended use of anticoagulants
Female subject of childbearing potential should have a negative urine or serum pregnancy within 72 hours prior to receiving the first dose of study medication; if the urine test is positive or cannot be confirmed as negative, a serum pregnancy test will be required
Female subjects of childbearing potential should be willing to use 2 methods of birth control or be surgically sterile, or abstain from heterosexual activity for the course of the study through 120 days after the last dose of study medication; subjects of childbearing potential are those who have not been surgically sterilized or have not been free from menses for > 1 year
Male subjects should agree to use an adequate method of contraception starting with the first dose of study therapy through 120 days after the last dose of study therapy
Subject meets institutional requirements for IL-2 therapy

Exclusion Criteria:

Has primary ocular melanoma
Is currently participating and receiving study therapy or has participated in a study of an investigational agent and received study therapy or used an investigational device within 4 weeks of the first dose of treatment
Has a diagnosis of immunodeficiency or is receiving systemic immunosuppressive steroid therapy or any other form of systemic immunosuppressive therapy within 7 days prior to the first dose of trial treatment; exception: physiologic corticosteroid replacement therapy for adrenal or pituitary insufficiency is not considered systemic immunosuppressive steroid therapy
Has received previous high dose IL-2 therapy, any programmed death (PD)-1 blocking antibody (e.g. pembrolizumab, nivolumab), or any programmed death ligand (PD-L)1 blocking antibody in the metastatic setting; prior therapy with any PD-1 blocking antibody is allowed if given in the adjuvant setting and the last dose was > 6 months prior to study entry; prior therapy with ipilimumab is allowed (in the adjuvant or metastatic setting); other prior therapy (in the adjuvant or the metastatic setting) is allowed, including targeted therapy, chemotherapy, or experimental therapy
Has a history of significant congestive heart failure or significant pulmonary disease
Has a known history of active TB (bacillus tuberculosis)
Hypersensitivity to pembrolizumab or any of its excipients
Has had a prior anti-cancer monoclonal antibody (mAb) within 4 weeks prior to study day 1 or who has not recovered (i.e., =< grade 1 or at baseline) from adverse events due to agents administered more than 4 weeks earlier

Has had prior chemotherapy, targeted small molecule therapy, or radiation therapy within 2 weeks prior to study day 1 or who has not recovered (i.e., =< grade 1 or at baseline) from adverse events due to a previously administered agent

Note: subjects with =< grade 2 neuropathy and/or alopecia are exceptions to this criterion and may qualify for the study
Note: if subject received major surgery, they must have recovered adequately from the toxicity and/or complications from the intervention prior to starting therapy
Has a known additional malignancy that is progressing or requires active treatment; exceptions include basal cell carcinoma of the skin or squamous cell carcinoma of the skin that has undergone potentially curative therapy or in situ cervical cancer
Has known active central nervous system (CNS) metastases and/or carcinomatous meningitis; subjects with previously treated brain metastases may participate provided they are stable (without evidence of progression by imaging for at least four weeks prior to the first dose of trial treatment and any neurologic symptoms have returned to baseline), have no evidence of new or enlarging brain metastases, and are not using steroids for at least 7 days prior to trial treatment; this exception does not include carcinomatous meningitis which is excluded regardless of clinical stability
Has active autoimmune disease that has required systemic treatment in the past 2 years (i.e. with use of disease modifying agents, corticosteroids or immunosuppressive drugs); 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
Has known history of, or any evidence of active, non-infectious pneumonitis
Has an active infection requiring systemic therapy
Has a history or current evidence of any condition, therapy, or laboratory abnormality that might confound the results of the trial, interfere with the subject's participation for the full duration of the trial, or is not in the best interest of the subject to participate, in the opinion of the treating investigator

Has received a live vaccine within 30 days of planned start of study therapy

Note: seasonal influenza vaccines for injection are generally inactivated flu vaccines and are allowed; however intranasal influenza vaccines (e.g., Flu-Mist) are live attenuated vaccines, and are not allowed
