Brief summary

This ambispective observational cohort study will evaluate the clinical performance of the ClarityDX Prostate blood test in men with a prostate-specific antigen (PSA) level of 3 ng/mL or higher who are undergoing prostate biopsy due to suspicion of prostate cancer. The study will compare ClarityDX Prostate test results with biopsy outcomes to determine the test's ability to identify the presence of clinically significant prostate cancer.

Detailed description

The main objective of this study is to validate ClarityDX Prostate as a reflex test to PSA to refine the prediction of clinically-significant prostate cancer in a prospective cohort of men to be recruited in North America when they are scheduled for a biopsy as a result of on an elevated PSA or other suspicion of prostate cancer and in retrospective databases from selected sites in the United States of America and the world. The training and validation analysis sets will consist of up to 2,800 consenting men from Alberta in addition to up to 5,000 men from external institutions, between ages 40-75 (inclusive) years old, without prior diagnosis of prostate cancer, who have been selected to undergo a prostate biopsy to rule out prostate cancer.

Design outcomes

Primary

MeasureTime frameDescription
Diagnostic Clinical Performance: prediction of clinically significant prostate cancer at biopsy3 yearsTraining Phase: Processed clinical features of each patient will be analyzed using machine learning to predict clinically significant prostate cancer, with the output being the ClarityDX Prostate Risk Score. Validation Phase: The models created during the Training Phase will be locked down and then used to determine the probability of approximately 1,400 patients in the investigational Validation Phase having clinically significant prostate cancer.
Active Surveillance: prediction of Gleason Grade Group on confirmatory/follow-up biopsies for participants on Active Surveillance4 years
MRI: prediction of PI-RADS pre-diagnostic biopsy4 years
