Scientific titleBiopSave: a blinded, prospective, non-randomised observational controlled study to validate a novel proteomic blood test for the diagnosis of prostate cancer
Study acronymBiopSave
Study hypothesisIt is hypothesised that a panel of candidate biomarkers, identified during an earlier pilot study as being present in the blood of prostate cancer patients, can be measured using the Biosignatures proteomics platform and successfully used to predict the likelihood of a patient having prostate cancer diagnosed by prostate biopsy. Diagnostic predictions will be made blinded to biopsy result and the accuracy of these predictions compared to actual biopsy results at designated analysis milestones by an independent data monitoring committee. The null hypothesis is that the candidate biomarkers identified during the pilot study had a coincidental association with the patients known to have prostate cancer in that cohort and therefore have no ability to make diagnostic predictions regarding the likelihood of prostate cancer being detected by prostate biopsy in newly recruited patients.
Ethics approval(s)NRES Committee South Central - Oxford C, 19/07/2012, ref: 12/SC/0432
ConditionProstate cancer in-vitro diagnostic assay validation
InterventionAside from taking of blood samples on one occasion, the study is non-interventional.
Intervention typeOther
Primary outcome measureA validation of the performance of the Biosignatures BiopSave product, demonstrating the capability of this proteomic blood test to predict the diagnostic results of prostate biopsies carried out on patients presenting for assessment at urology clinic with the suspicion of having an undiagnosed prostate cancer, particularly those patients in a specific sub-set: PSA concentration between 2.5 and 20 ng/ml, DRE findings not immediately suspicious of prostate cancer, have not undergone previous prostate biopsy or resection procedures.
Secondary outcome measures1. A validation of the performance of the BiopSave product in patients who have a PSA concentration outside of the primary range of interest and/or who have DRE findings which are suspicious of prostate cancer and/or who have had prostate biopsy or resection procedures carried out in the past.
2. A comparison of the performance of the BiopSave product to a variety of other prostate disease biomarkers recently reported in the literature.
3. An assessment of the capability of the BiopSave product, or related refined versions of the assay to predict the overall prostate disease diagnostic status of study participants one year after initial prostate biopsy.

IPD sharing planThe datasets generated during and/or analysed during the current study are/will be available upon request from David Miller.

Added 04/05/2021:
The datasets generated during and/or analyzed during the current study are/will be available upon request from Biosignatures Ltd.
What data in particular will be shared? All of the individual participant data collected during the trial, after deidentification.
What other documents will be available? Study protocol, informed consent form, clinical study report.
When will data be available (start and end dates)? Immediately following publication. No end date.
With whom? Investigators whose proposed use of the data has been approved by and independent review committee (IRB/Ethics Committee).
For what types of analyses? To achieve the aims in the approved proposal.
By what mechanism will data be made available? Proposals should be directed to the Newcastle Biobank (https://www.ncl.ac.uk/biobanks/researchers/sample-access/)
Whether participant consent was obtained? Participants gave consent for the use of their blood samples and deidentified data to be used for future research, as a “gift to science”.
Comments on data anonymization. Identifiable data was not accessed outside of the care team. At recruitment participants were assigned a unique alpha-numeric identification code by research nursing staff. All information and blood samples which left the clinical site were only identifiable by this unique code.
Any ethical or legal restrictions? None.
