Brief summary

This is a minimal risk correlative clinical blood-drawing protocol. The objective of this lead in pilot component is to determine whether Circulating Tumor Cells (CTC's) can be captured using the novel mesenchymal-marker based Near Infrared-Emissive Polymersomes (NIR-EPs), the PSMA-based NIR-EP, and the epithelial EpCAM-based NIR-EP. If successful, the capture method will be evaluated further in the larger comparative study.

Inclusion criteria

* histologically confirmed diagnosis of adenocarcinoma of the prostate * Clinical or radiographic evidence of metastatic disease * Evidence of disease progression on androgen deprivation therapy (ADT) as evidenced by either of the following in the past: 1. Two consecutive PSA levels greater than the PSA nadir achieved on ADT, separated by greater than one week 2. Radiographic evidence of disease progression as defined by new bone scan lesions or soft tissue/visceral metastases \>2 cm in diameter. 3. Clinical progression as determined by the treating physician. * Age greater than 18 years. * Ability to understand and the willingness to sign a written informed consent document

Exclusion criteria

* History of intercurrent or past medical or psychiatric illness that would make participation in a blood drawing protocol difficult or not feasible at the discretion of the principal investigator or co-investigator(s)

Design outcomes

Primary

MeasureTime frameDescription
Change in Non-detection rate of CTC's in men with CRPCat baseline, month 3, and progression (up to 18 months)Non-detection rate of CTC's in men with CRPC will be measured at baseline, month 3, and at progression

Secondary

MeasureTime frameDescription
Correlation of CTC enumeration with therapiesat baseline, month 3, and progression (up to 18 months)
Median number of CTC's detected by each capture methodbaseline, month 3, and progression (up to 18 months)Calculate for each patient the number of CTC's detected by each capture method (novel and standard).
Change in median number of CTC's for each methodat baseline, month 3, and progression (up to 18 months)For each method, we will plot the change across time (baseline, cycle 3, and at progression) in the median number of CTC's for each method (novel and standard).
Correlation of CTC enumeration with presenting clinical stageat baseline, month 3, and progression (up to 18 months)
Correlation of CTC enumeration with PSA kineticsat baseline, month 3, and progression (up to 18 months)
Correlation of CTC enumeration with Gleason sumat baseline, month 3, and progression (up to 18 months)
Correlation of CTC enumeration with overall survivalat baseline, month 3, and progression (up to 18 months)
Correlation of CTC enumeration with progression-free survivalat baseline, month 3, and progression (up to 18 months)
Correlation of CTC enumeration with response to therapyat baseline, month 3, and progression (up to 18 months)
Correlation of CTC enumeration with sites of metastatic diseaseat baseline, month 3, and progression (up to 18 months)
