  Purpose

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.

Primary Outcome Measures:
  • MTD of the combination of ipilimumab with GM-CSF that results in < 33% DLT [ Time Frame: Continuously ] [ Designated as safety issue: No ]
    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.


Secondary Outcome Measures:
  • Adaptive immunity [ Time Frame: 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 ] [ Designated as safety issue: No ]
    Measured through peripheral blood collection. Three and four-color immunofluorescence and flow cytometric analysis will be employed to determine relative numbers of activated T cells. Specifically, percentages of T cells (CD3+, CD4+ or CD8+) expressing the activation markers HLA-DR, CD25 and CD69 will be determined. Also, percentages of naive (CD45RA+) and memory (CD45RO+) T cells will be determined.

  • PSA and/or objective response for measurable disease [ Time Frame: Day 1 ] [ Designated as safety issue: No ]
    Evaluated according to Response Evaluation Criteria in Solid Tumors (RESIST) criteria. PSA Response will be evaluated according to the recommendations from National Cancer Institute PSA Working Group. 95% confidence interval will be provided.

  • Safety of the regimen [ Time Frame: Continuously ] [ Designated as safety issue: Yes ]
    Graded according to the NCI common toxicity criteria, version 3.0.

  • Anti-idiotype antibody (human anti-human antibodies [HAHA]) development [ Time Frame: Baseline, before each ipilimumab infusion and 2 months after the last infusion of antibody ] [ Designated as safety issue: No ]
    A semi-quantitative ELISA assay will be used to detect IgG antibodies to Ipilimumab in the plasma samples.

  • Pharmacokinetic (PK) Studies [ Time Frame: Prior to and 60 minutes after all infusions, and at 1 and 2 months after the last ipilimumab infusion ] [ Designated as safety issue: No ]
    Determined using a quantitative ELISA.


Enrollment: 42
Study Start Date: May 2003
Primary Completion Date: January 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Treatment (monoclonal antibody, colony-stimulating factors)
Patients 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.

Detailed Description:

PRIMARY OBJECTIVES:

I. Determine the maximum tolerated dose of anti-cytotoxic T-lymphocyte-associated antigen-4 monoclonal antibody (MDX-010) (ipilimumab) administered with sargramostim (GM-CSF) in patients with metastatic androgen-independent prostate cancer. (Phase I) II. Determine the safety of this regimen in these patients. (Phase I) III. Evaluate the efficacy as measured by reduction in PSA associated with combining GM-CSF with CTLA-4 blockade with ipilimumab at a dosage of 3 mg/kg given monthly x 6 doses (d1 of courses 1-6). (Cohort Expansion)

SECONDARY OBJECTIVES:

I. Determine the T-cell immunity and T-cell response in patients treated with this regimen. (Phase I) II. Determine the pharmacokinetics of MDX-010 in these patients. (Phase I) III. Determine the prostate-specific antigen and/or objective responses in patients treated with this regimen. (Phase I) IV. Determine the percentages of activated, naive, and memory T-cells. (Cohort Expansion) V. Determine the measurement of T-cell response to describe epitopes from prostate antigens including PSA, PSMA, and PAP. (Cohort Expansion) VI. Quantitate T-cell response to antigens in patients with relevant HLA allele using HLA*0201 tetramers. (Cohort Expansion) VII. Evaluate the toxicity of this regimen in these patients. (Cohort Expansion) VIII. Determine the initial efficacy as measured by reduction in PSA associated with combining GM-CSF with CTLA-4 blockade with ipilimumab at a dosage of 3 mg/kg given monthly x 6 doses (d1 of courses 1-6). (Cohort Expansion) IX. Determine objective response by post-therapy measurable disease changes using RECIST criteria. (Cohort Expansion)

OUTLINE: This is a multicenter, dose-escalation study of ipilimumab.

Patients receive ipilimumab intravenously (IV) over 90 minutes on day 1 and sargramostim (GM-CSF) subcutaneously (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 maximum tolerated dose (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.

Patients are followed at 30 days.
