RATIONALE: Vaccines may make the body build an immune response to kill tumor cells. Biological therapies use different ways to stimulate the immune system and stop cancer cells from growing. Combining vaccine therapy with biological therapy may kill more tumor cells.
PURPOSE: Phase I trial to study the effectiveness in combining vaccine therapy and biological therapy in treating patients who have relapsed prostate cancer.
- Determine the optimal (in terms of antibody response) and safe dose range of glycosylated MUC-2-Globo H-KLH conjugate vaccine with adjuvant GPI-0100 in patients with biochemically relapsed prostate cancer.
- Assess post-immunization changes in prostate-specific antigen levels and other objective parameters of disease in these patients.
OUTLINE: This is a dose-escalation study of GPI-0100.
Patients receive glycosylated MUC-2-Globo H-KLH conjugate vaccine with adjuvant GPI-0100 subcutaneously weekly on weeks 0-2, 6, 14, and 26 in the absence of unacceptable toxicity or disease progression.
Cohorts of 5 patients receive escalating doses of GPI-0100 until the optimal dose, based on antibody response, is reached.
Patients are followed every 3 months.
PROJECTED ACCRUAL: A maximum of 25 patients will be accrued for this study.
Primary Purpose: Treatment
GPI-0100, MUC-2-Globo H-KLH conjugate vaccine
Memorial Sloan-Kettering Cancer Center
National Cancer Institute (NCI)

A pneumococcal vaccine which 7 pneumococcal serotypes (6B, 14, 19F, 23F, 18C, 4, 9V), each conjugated individually to the outer membrane protein complex of NEISSERIA MENINGITIDIS.
A glycoprotein that is a kallikrein-like serine proteinase and an esterase, produced by epithelial cells of both normal and malignant prostate tissue. It is an important marker for the diagnosis of prostate cancer.
A synthetic retinoid that is used orally as a chemopreventive against prostate cancer and in women at risk of developing contralateral breast cancer. It is also effective as an antineoplastic agent.
Tissue ablation of the PROSTATE performed by ultrasound from a transducer placed in the RECTUM. The procedure is used to treat prostate cancer (PROSTATIC NEOPLASMS) and benign prostatic hypertrophy (PROSTATIC HYPERPLASIA).
Proteins secreted by the prostate gland. The major secretory proteins from the human prostate gland include PROSTATE-SPECIFIC ANTIGEN, prostate-specific acid phosphatase, prostate-specific membrane antigen, and prostate-specific protein-94.
Biological therapy involves the use of living organisms, substances derived from living organisms, or laboratory-produced versions of such substances to treat disease. Some biological therapies for cancer use vaccines or bacteria to stimulate the body&rs...
An antibody is a protein produced by the body's immune system when it detects harmful substances, called antigens. Examples of antigens include microorganisms (such as bacteria, fungi, parasites, and viruses) and chemicals. Antibodies may be produc...
Head and neck cancers
Cancer can occur in any of the tissues or organs in the head and neck. There are over 30 different places that cancer can develop in the head and neck area. Mouth cancers (oral cancers) - Mouth cancer can develop on the lip, the tongue, the floor...
