Brief Summary
This phase I trial is studying the side effects and best dose of ipilimumab when given with sargramostim in treating patients with metastatic prostate cancer. Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Colony-stimulating factors, such as sargramostim, may increase the number of immune cells found in bone marrow or peripheral blood and may help a person's immune system kill more tumor cells.

Conditions
Outcome Measures
Primary Outcomes (1)
MTD of the combination of ipilimumab with GM-CSF that results in < 33% DLT
Graded according to the National Cancer Institute (NCI) common toxicity criteria, version 3.0. Results will be tabulated by dose cohort and overall for this trial. DLT is defined by any of the following that are attributable to therapy: any \>= grade 4 toxicity, any ocular toxicity considered immune mediated and requiring systemic steroids, any grade 3 toxicity considered immune mediated that cannot be controlled with systemic steroids.
Continuously
Secondary Outcomes (5)
Adaptive immunity
Baseline, days 1 and 14 of courses 1 and 2, day 1 of courses 3-6, and then day 1 of every other course throughout treatment
PSA and/or objective response for measurable disease
Day 1
Safety of the regimen
Continuously
Anti-idiotype antibody (human anti-human antibodies [HAHA]) development
Baseline, before each ipilimumab infusion and 2 months after the last infusion of antibody
Pharmacokinetic (PK) Studies
Prior to and 60 minutes after all infusions, and at 1 and 2 months after the last ipilimumab infusion
Study Arms (1)
Treatment (monoclonal antibody, colony-stimulating factors)
EXPERIMENTALPatients receive ipilimumab IV over 90 minutes on day 1 and sargramostim (GM-CSF) SC on days 1-14. Treatment repeats every 28 days for 4-6 courses. GM-CSF continues beyond 4 courses in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of ipilimumab until the MTD is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. Some patients undergo blood sample collection periodically for laboratory and pharmacokinetic studies. Samples are analyzed for human anti-human antibodies, IgG antibodies to ipilimumab semi-quantitative ELISA assay, and plasma concentrations of ipilimumab via quantitative ELISA assay.
