Overview
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.
Investigators
Eligibility Criteria
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:
- •Two consecutive PSA levels greater than the PSA nadir achieved on ADT, separated by greater than one week
- •Radiographic evidence of disease progression as defined by new bone scan lesions or soft tissue/visceral metastases \>2 cm in diameter.
- •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)
Outcomes
Primary Outcomes
Change in Non-detection rate of CTC's in men with CRPC
Time Frame: at 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 Outcomes

- Correlation of CTC enumeration with therapies(at baseline, month 3, and progression (up to 18 months))
- Median number of CTC's detected by each capture method(baseline, month 3, and progression (up to 18 months))
- Change in median number of CTC's for each method(at baseline, month 3, and progression (up to 18 months))
- Correlation of CTC enumeration with presenting clinical stage(at baseline, month 3, and progression (up to 18 months))
- Correlation of CTC enumeration with sites of metastatic disease(at baseline, month 3, and progression (up to 18 months))
