ClinicalTrials.gov Identifier:	NCT00814892

Purpose

RATIONALE: Vaccines made from tumor cells or dendritic cells may help the body build an effective immune response to kill tumor cells. It is not yet known which vaccine is more effective in treating patients with prostate cancer.

PURPOSE: This randomized phase II trial is studying two different types of vaccines to compare how well they work in treating patients with non-metastatic prostate cancer.

Arms	Assigned Interventions
Arm I: Experimental Patients receive allogeneic prostate cancer cell vaccine (APCC) intradermally (ID) on days 0, 14, and 28 and then every 28 days for up to 14 courses in the absence of disease progression or unacceptable toxicity.	Drug: allogeneic tumor cell vaccine Given intradermally
Arm II: Experimental Patients undergo standard leukapheresis to harvest peripheral blood mononuclear cells for dendritic cell vaccine preparation. Patients receive the APCC vaccine and autologous dendritic cells derived from CD14-positive myeloid peripheral blood cells ID on days 0, 14, and 28 and then every 28 days for up to 14 courses in the absence of disease progression or unacceptable toxicity.

Drug: allogeneic tumor cell vaccine

Given intradermally

Detailed Description:

OBJECTIVES:

Primary

To compare the progression-free survival rate at 1 year in patients with androgen-independent non-metastatic prostate cancer treated with allogeneic prostate cancer cell vaccine (APCC) with vs without autologous myeloid dendritic cells.

Secondary

To compare the toxicities of these regimens in these patients.
To compare the overall survival, progression-free survival, time to PSA progression, and duration of PSA-based response in patients treated with these regimens.
To compare the quality of life of patients treated with these regimens.
To evaluate the ability of the novel dendritic cell-APCC vaccination strategies to induce vaccine-specific immune response in these patients.

OUTLINE: Patients are stratified according to 2-year survival probability (< 30% vs ≥ 30%). Patients are randomized to 1 of 2 treatment arms.

Arm I: Patients receive allogeneic prostate cancer cell vaccine (APCC) intradermally (ID) on days 0, 14, and 28 and then every 28 days for up to 14 courses in the absence of disease progression or unacceptable toxicity.
Arm II: Patients undergo standard leukapheresis to harvest peripheral blood mononuclear cells for dendritic cell vaccine preparation. Patients receive the APCC vaccine and autologous dendritic cells derived from CD14-positive myeloid peripheral blood cells ID on days 0, 14, and 28 and then every 28 days for up to 14 courses in the absence of disease progression or unacceptable toxicity.

Patients undergo blood sample collection periodically for translational studies. Samples are measured for a number of immune parameters by quantifying T-cell and dendritic cell populations by analysis of surface marker molecules by flow cytometry, T-cell proliferation assay, non-specific cytokine release, lysate-specific cytokine release, and cytokine expression measured by cytometric bead array and qPCR.

Patients complete quality-of-life questionnaires periodically.

After completion of study treatment, patients are followed periodically for up to 3 years.
