Inclusion Criteria:

- Histologic diagnosis of metastatic uveal melanoma; the tumor biopsy/aspiration must
be available for review

- Patients must have measurable disease as defined by Response Evaluation Criteria in
Solid Tumors (RECIST)

- Patients must have liver metastasis

- No more than one prior systemic therapeutic regimen; this includes chemotherapy,
biologic therapy, biochemotherapy, or investigational treatment; this does not
include any therapies given in the adjuvant setting

- No concomitant therapy with any of the following: interleukin-2 (IL-2), interferon,
or other non-study immunotherapy regimens; cytotoxic chemotherapy; immunosuppressive
agents; other investigation therapies; or chronic use of systemic corticosteroids;
must have been discontinued > 4 weeks

- Patients with prior hepatic embolization procedures are eligible as long as they are
candidates for repeat procedures and they have demonstrated progressive disease

- No infection with human immunodeficiency virus (HIV); due to the mechanism of action
of ipilimumab, activity and side effects in an immune compromised patient are unknown

- No active infection with hepatitis B

- No active or chronic infection with hepatitis C

- Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1

- Women must not be pregnant or breast-feeding due to unknown effects of treatments on
the unborn fetus; all women of childbearing potential must have a blood test within
72 hours prior to randomization to rule out pregnancy; women of childbearing
potential and sexually active males must be strongly advised to use an accepted and
effective method of contraception; women of childbearing potential (WOCBP) must be
using an adequate method of contraception to avoid pregnancy throughout the study and
for up to 12 weeks after the last dose of investigational product, in such a manner
that the risk of pregnancy is minimized; sexually mature females who have not
undergone a hysterectomy or who have not been postmenopausal naturally for at least
24 consecutive months (i.e., who have had menses at some time in the preceding 24
consecutive months) are considered to be of childbearing potential; women who are
using oral contraceptives, other hormonal contraceptives (vaginal products, skin
patches, or implanted or injectable products), or mechanical products such as an
intrauterine device or barrier methods (diaphragm, condoms, spermicides) to prevent
pregnancy, or are practicing abstinence or where their partner is sterile (e.g.,
vasectomy) should be considered to be of childbearing potential

- White blood cell (WBC) >= 2000/uL

- Absolute neutrophil count (ANC) >= 1500/mcL

- Platelets >= 100,000/mcL

- Hemoglobin >= 8 g/dL

- Creatinine =< 3.0 x upper limit of normal (ULN)

- Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) < 2.5 x ULN

- Bilirubin =< 2.0 x ULN, (except patients with Gilbert's Syndrome, who must have a
total bilirubin less than 3.0 mg/dL)

- Albumin >= 3 g/dL

Exclusion Criteria:

- Patients are excluded if they have liver tumor volume > 50%

- Patients are excluded if they have any history of central nervous system (CNS)
metastases

- Patients are excluded if they have a history of any other malignancy from which the
patient has been disease-free for less than 2 years, with the exception of adequately
treated and cured basal or squamous cell skin cancer, superficial bladder cancer or
carcinoma in situ of the cervix

- Patients are excluded if they have a history of autoimmune disease, as follows:
patients with a history of inflammatory bowel disease are excluded from this study as
are patients with a history of symptomatic disease (e.g., rheumatoid arthritis,
systemic progressive sclerosis [scleroderma], systemic lupus erythematosus,
autoimmune vasculitis [e.g., Wegener's granulomatosis]); patients with motor
neuropathy considered of autoimmune origin (e.g., Guillain- Barre syndrome and
myasthenia gravis) are excluded; patients with a history of autoimmune thyroiditis
are eligible if their current thyroid disorder is treated and stable with replacement
or other medical therapy

- Patients are excluded for any underlying medical or psychiatric condition, which in
the opinion of the investigator, will make treatment hazardous or obscure the
interpretation of adverse events, such as a condition associated with frequent
diarrhea

- Patients are excluded if they have a history of prior treatment with ipilimumab or
prior tumor necrosis factor receptor superfamily, member 9 (CD137) agonist or
cytotoxic T-lymphocyte antigen 4 (CTLA-4) inhibitor or agonist

- Patients are excluded for receiving any non-oncology vaccine therapy used for
prevention of infectious diseases for up to four weeks (28 days) prior to or after
any dose of ipilimumab

- Patients are excluded if they have any concurrent medical condition requiring the use
of systemic steroids (the use of inhaled or topical steroids is permitted)

- Patients are excluded if they have a functional organ transplant
