We will be developing a genomic based signature of "BRCAness" based on literature of genomic signatures from women with breast cancer and germline BRCA mutations.The "BRCAness" breast cancer signature will differentiate germline BRCA 1/2 breast cancers from standard estrogen-receptor (+) breast cancers. We will obtain a library of genomic signatures Recently these techniques have been used to develop a transcriptional "signature" for androgen receptor (AR) activity in men with CRPC(Castration Resistant Prostate Cancer). The investigator will apply the "BRCAness" breast cancer signature to pathological prostate cancer specimens to determine the percentage of patients in the overall prostate cancer population that express this signature, as well as the clinical and histological phenotype of this population.
This novel prostate cancer "BRCAness" signature will be developed over a period of 4-6 months. This "BRCAness" signature has not previously been evaluated in prostate cancer patients and would be expected, based on known characteristics of BRCA mutant breast and ovarian cancers, to be more platinum-responsive. Relevant clinical data, including histology, grade, stage, size of residual tumor, recurrence, and survival, will be obtained from outpatient and inpatient charts to perform subsequent correlative studies.
All patients enrolled in the phase II clinical trial with satraplatin will have pre-treatment biopsies of metastatic sites. All of the specimens will be frozen, batched and stored as previously described. We anticipate that all patients will be enrolled 16 months from when the trial opens. When the last patient is enrolled in the trial and all of the metastatic biopsies have been collected, they will be shipped in bulk on dry ice to laboratory for RNA(ribonucleic acid) isolation, RNA quality assessment and processing, microarray hybridization, microarray data quality assessment, and "BRCAness" prostate cancer signature application. Frozen biopsies will be processed for microarray analysis using laser capture microdissection and RNA amplification using adaptations of previously published methods. The application of the prostate cancer BRCAness signature will take place over two months.

Other Name: JM-118
- Efficacy of Satraplatin as Second Line Therapy in Men With CRCP [ Time Frame: 3 months ]Patients with good tolerance of treatment who have a 30% PSA decline from their pre-treatment level within 3 months of treatment initiation will be considered responders provided objective tumor measurements are stable or also demonstrate response.
- Number of Days to Maximum Decline in PSA [ Time Frame: baseline and 3 months ]Response rate - Maximum decline in PSA that occurs during treatment.
- Progression Free Survival (PFS) [ Time Frame: up to 2 years ]Progression Free Survival is measured from the time of the initiation of therapy until the first date that recurrent or progressive disease is objectively documented. Progression is a composite endpoint that can be based upon PSA, objective measures of disease, symptoms or death. Time to disease progression.
- Overall Survival [ Time Frame: 24 months ]Patients followed for a minimum of 24 months or until death. Patients and/or their family members will be contacted via telephone calls or certified letter.
