[18F]-Fluoro-2-Deoxy-D-Glucose and -[18F] Dihydro-Testosterone Pet Imaging in Patients With Progressive Prostate Cancer - Full Text View

Sponsor:	Memorial Sloan-Kettering Cancer Center
Information provided by (Responsible Party):	Memorial Sloan-Kettering Cancer Center
ClinicalTrials.gov Identifier:	NCT00588185

Purpose

This study will use PET scans, which is a type of x-ray test that uses a radiotracer, to see whether these scans may be better able to find places in the body where your prostate cancer may have spread.

Primary Outcome Measures:

To study the accumulation and biodistribution of FDHT in patients with progressive prostate cancer. The accumulation and location of FDHT activity will be assessed on a site by site basis and correlated with radionuclide bone scan, CT and MRI. [ Time Frame: Baseline, 4 weeks and 12 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

The kinetics, metabolism, and biodistribution will be assessed. [ Time Frame: Baseline. 4 weeks and 12 weeks ] [ Designated as safety issue: No ]
To correlate the accumulation of 18FDHT to 18FDG. [ Time Frame: 2 years ] [ Designated as safety issue: No ]
To study changes in 18FDHT accumulation over time in patients treated with: Castration and other hormones, Chemotherapy, Agents directed toward the androgen receptor [ Time Frame: 2 years ] [ Designated as safety issue: No ]

Experimental: 1 [18F]-Fluoro-2-Deoxy-D-Glucose and -[18F] Dihydro-Testosterone	Drug: [18F]-Fluoro-2-Deoxy-D-Glucose and -[18F] Dihydro-Testosterone Registered patients will undergo PET scanning using either FDG alone or FDG followed by FDHT, depending on the availability of the tracer. Scans will be performed serially at baseline, week 4, week 12, and every 12 weeks of treatment up to a maximum of 5 FDHT scans in a 12 month period, unless the therapeutic protocol or scientific rationale of the therapeutic drug being applied specifically dictates an alternative schedule.

Detailed Description:

Our preliminary studies have shown that whole body FDG-PET imaging identifies areas of abnormal metabolism in a majority of tumor sites in patients with progressive disease and that changes in FDG accumulation parallel changes in PSA after treatment. This suggests that changes in FDG metabolism may provide an early assessment of treatment outcomes. In previous work we established a methodology to examine a radiotracer in patients with progressive disease and abnormal imaging studies, which we have applied to the clinical states of non-castrate and castrate metastatic disease. This design is characterized by:

1) Evaluation of uptake on a site-by-site basis in relation to conventional studies 2) Standardization of uptake values in tumor relative to a normal organ 3) Controlling for progression using standard measures of progression including a rising PSA, new or enlarging lesions on bone or transaxial imaging, and new symptoms of disease. In the present study we are evaluating fluorinated dihydrotestosterone (FDHT) in addition to FDG. FDHT is targeted to the AR and has been shown in preliminary studies to visualize prostate cancers in man. This study will apply our established methods to investigate FDHT imaging in patients with progressive prostate cancer. In the selected cases where tumor is available, we will study associations between FDHT accumulation and AR expression.
