A Phase I/II Study of Clinical and Molecular Correlates of Positron Emission Tomography (PET) With 89Zr-DFO-huJ591 in Metastatic Prostate Cancer
The purpose of this study is to define the safety and accuracy of 89Zr-DFO-huJ591 PET scans.
By improving our ability to find cancer cells, the investigators hope to be able to improve
treatment for patients in the future.
The study doctors want to determine whether a new kind of scan, called a 89Zr-DFO-huJ591 PET
scan, can specifically see prostate cancer that has spread to other parts of the body,
especially the bones. The study doctors will also look at how the 89Zr-DFO-huJ591 reacts with
the body and how long it stays in the body. The investigators will also ask the patient to
have a biopsy performed. The study doctors will compare the findings the investigators see on
the scans with findings on the optional tissue biopsy. Finally, the investigators will
compare the pictures from a 89Zr-DFO-huJ591 PET scan with those of a standard PET scan
(called FDG PET) and standard CT scans or magnetic resonance (MRI) scans or bone scans,
depending on which standard scans the doctor has ordered.
PET scanning uses a small amount of radiation attached to a molecule that is taken up by the
cancer. In this trial, the patient will undergo two types of PET scans. One uses FDG. FDG is
a standard tracer for PET scans. The patient will also undergo another type of PET scan that
is experimental. This experimental PET uses a radioactive protein called J591. The radiation
source is a type of metal called zirconium-89 (89Zr). The whole tracer, J591 plus the 89Zr,
is abbreviated as 89Zr-DFO-huJ591. This tracer is what is being studied. The tracer used in a
scan should find where the cancer is in the body.

Inclusion Criteria:
Metastatic Prostate Cancer Patients:
- Adult male ≥ 18 years of age
- Patients with histologically confirmed prostate cancer at MSKCC
- Progressive disease manifest by either:
- Imaging modalities:
- Bone Scan: New osseous lesions on bone scan and/or

- Radiographic evaluation involving bone imaging and cross sectional imaging of at least
the pelvis that is negative or equivocal for metastatic disease
- Performance status of 60 or higher (Karnofsky scale) (Appendix B)
- Ability to understand and willingness to sign a written informed consent document
Exclusion Criteria:
