Clinical Trial Summary

BARCODE 1 is a screening study designed to investigate the role of genetic profiling for targeting population prostate cancer screening. A pilot of 300 men were recruited aiming to inform the feasibility and accessibility of the study approach. The full study is an extension of the pilot study aiming to recruit a total of 5000 men.


Clinical Trial Description

The BARCODE 1 study aims to evaluate genetic profiling using the known ~170 prostate cancer (PrCa) risk single-nucleotide polymorphisms (SNPs) as a means of offering targeted screening for PrCa in men at a genetically higher risk. Initially, 300 men were recruited via participating General Practices (GPs). The full study aims to recruit an additional 4700 participants. Men aged 55-69 years who are likely to be eligible for the study will be identified by GPs from medical records. Participants will be contacted via invitation letters from GPs and if interested in the study will be asked to sign a consent form and complete a questionnaire to confirm eligibility to participate. If eligible, men will then be sent a DNA collection saliva kit. DNA from saliva will be analysed with SNP profiling for the known ~170 clinically relevant SNPs. Men with a genetic risk equivalent to the top 10% of the population distribution (approximately 470 men in total from the full study) will be invited for an MRI and a transrectal ultrasound (TRUS) prostate biopsy, plus further biological samples. Biopsy results will be correlated with the genetic score. The study also aims to determine the incidence and aggressiveness of prostate cancer in men within the top 10% of the genetic score. Furthermore, the association of MRI appearance and biological sample biomarker profile with prostate biopsy result in men at genetically higher prostate cancer risk undergoing targeted screening will also be determined. ;
