RATIONALE: Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells.
- Determine the antitumor effects of monoclonal antibody huJ591 in patients with progressive androgen-independent prostate cancer.
- Determine the biodistribution and dosimetry of this antibody in these patients.
- Determine the effect on biodistribution of the delivery sequence of unlabeled vs indium In 111-labeled antibody in these patients.
- Determine the HAHA response in patients treated with this regimen.
- Correlate the dose of monoclonal antibody huJ591 with antibody-dependent cellular cytotoxicity in these patients.
OUTLINE: Patients are assigned to one of two treatment groups.
- Group I: Patients receive monoclonal antibody huJ591 IV followed by indium In 111 monoclonal antibody huJ591 on day 1.
- Group II: Patients receive monoclonal antibody huJ591 concurrently with indium In 111 monoclonal antibody huJ591 as in group I.
Treatment in both groups repeats every 3 weeks for 4 courses in the absence of disease progression or unacceptable toxicity.
Patients are followed for 4 weeks and then monthly for 3 months.
PROJECTED ACCRUAL: A total of 14 patients (7 per treatment group) will be accrued for this study.
Primary Purpose: Treatment

The purpose of this study is to find out how effective 177Lu -J591 is in the treatment of patients with metastatic, androgen-independent prostate cancer.
RATIONALE: Monoclonal antibodies, such as anti-IL-6 chimeric monoclonal antibody, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others...

10 patients will be enrolled in the initial cohort and will receive two infusions of unlabeled huJ591 on days 1 and 14. 89Zr-J591 will be administered on day 21 (+ 1 day) and a positron em...
RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Monoclonal antibodies such as bevacizumab may stop the growth of can...
PSMA (prostate-specific membrane antigen) is overexpressed in prostate cancer cells and is reported to be a promising target for antibody-based radioligand therapy in patients with metastasized prosta...
This study is an investigation for an inexpensive, simple and sensitive biosensor to detect prostate cancer using bioactivated-multi wall carbon nanotubes (MWCNTs, diameter of 20nm, length of 5µm) an...
Prostate cancer is the most commonly diagnosed non-skin cancer in men. Screening for prostate cancer is widely accepted; however concerns regarding the harms outweighing the benefits of screening exis...
The epithelial cell adhesion molecule (EpCAM), or CD326, was one of the first cancer associated biomarkers to be discovered. In the last forty years, this biomarker has been investigated for use in pe...
Nerves are key factors in prostate cancer (PCa), but the functional role of innervation in prostate cancer is poorly understood. PCa induced neurogenesis and perineural invasion (PNI), are associated ...
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 humanized monoclonal antibody against the ERBB-2 RECEPTOR (HER2). As an ANTINEOPLASTIC AGENT, it is used to treat BREAST CANCER where HER2 is overexpressed.
An anti-VEGF recombinant monoclonal antibody consisting of humanized murine antibody. It inhibits VEGF receptors and prevents the proliferation of blood vessels.
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).
In a clinical trial or interventional study, participants receive specific interventions according to the research plan or protocol created by the investigators. These interventions may be medical products, such as drugs or devices; procedures; or change...
