Prostate Cancer Risk Identification in a Multi-Ethnic Cohort: a Prospective US-based Multi-center Validation Study of Proclarix
Sponsor: Sequenom, Inc.
Summary
The study is a prospective, multi-center, single cohort study involving up to 10 urological clinics in the US. After provision of informed consent and prior to the scheduled prostate biopsy (≤30 days), up to 20 mL of whole blood will be collected from each subject. The samples will be blinded and sent to Labcorp for evaluation using the Proclarix® assay. Prostate biopsy will be performed according to standard clinical practice of the urologist (systematic, targeted, or combined biopsy with a transrectal or transperineal approach with or without prior magnetic resonance imaging (MRI)). A minimum of 10 cores are required. Histopathological examination of the biopsy specimen will be performed according to the established local practice. A csPCa is defined as ISUP Grade Group ≥2 detected on biopsy. The assay results will be compared to the biopsy results.

Proclarix
Proclarix® is a blood-based test that addresses the problem of prostate cancer (PCa) overdiagnosis by indicating the risk of clinically significant disease. It is comprised of two novel biomarkers, thrombospondin 1 (THBS1) and cathepsin D (CTSD), and is combined with total prostate-specific antigen (tPSA), free PSA (fPSA) and age.
