Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This prospective, non-therapeutic translational biomarker study will collect blood in patients with high risk localized prostate cancer prior to prostatectomy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The Vogelstein lab has developed a highly sensitive, tumor-informed method of detecting circulating free DNA (cfDNA) shed by solid tumors. Plasma will be assayed for ctDNA using the SaferSeqS tumor-informed assay, employing DNA sequences derived from prostatectomy specimens. The abundance and molecular characteristics of ctDNA will be evaluated for a pilot group of 12-24 patients using an adaptive statistical design.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Must have histologically confirmed prostate cancer.
2. Age ≥ 18 years.
3. ECOG performance status of 0-1.
4. Must have the ability to understand and the willingness to sign a written informed consent document.
5. Willing to provide serial blood samples for the study.
6. Willing to provide tumor tissue (prostatectomy for primary cohort; prostatectomy or biopsy for exploratory cohort) for correlative studies which will compare ctDNA to tumor specimens.
7. Primary Cohort: High-risk localized prostate adenocarcinoma defined as one or more of the following:

o Clinical stage ≥ cT3a, Grade Group 4 or 5 (Gleason sum 8-10), and PSA ≥ 20

\*Non-bulky pelvic lymphadenopathy and indeterminate findings on staging imaging (CT, bone scan, PSMA PET CT) are allowed if the surgeon believes RP is appropriate.
8. Exploratory Cohort: Men with a diagnosis of prostate adenocarcinoma and one of the following:

* Localized prostate adenocarcinoma on active surveillance
* Biochemically-recurrent prostate adenocarcinoma after definitive local therapy
* Hormone-sensitive, metastatic prostate adenocarcinoma
* Metastatic CRPC

Exclusion Criteria

1. History of another primary cancer within the last 3 years, except for non-melanomatous skin cancer.
2. Receiving androgen deprivation or other systemic therapy for prostate cancer.
3. Medical condition or social situation that may preclude adherence to the protocol.
