Determination of Prevalence and Features of HRRm mCRPC (ADAM)

Completed

• Conditions: HRRm mCRPC

• Registration Number: NCT04712890
• Lead Sponsor: AstraZeneca

Brief Summary

Study design:

This study is local, multi-center, prospective, cohort study to collect real world data related mCRPC patients, prevalence of HRRm and to assess possible influence of HRRm on treatment outcomes. No additional procedures besides those already used in the routine clinical practice will be applied to the patients. Treatment assignment will be done according to the current practice.

Data Source(s):

For testing archival samples (formalin fixed and paraffin embedded \[FFPE\]) from primary tumor will be used . 15 HRR genes (BRCA1, BRCA2, ATM, BRIP1, BARD1, CDK12, CHEK1, CHEK2, FANCL, PALB2, PPP2R2A, RAD51B, RAD51C, RAD51D and RAD54L) will be analyzed using NGS in dedicated central laboratory facilities. Choice of laboratory for each center will be made based on logistical proximity. Each NGS laboratory will have to determine and report clinical significance of alterations found using database search or other predictors to classify variants as deleterious or suspected deleterious. VUS have to be reported separately. Benign variants will be not reported in this study.

All clinical and demographic data for patients with finished therapy will be collected in prospective or retrospective (where applicable) manner during the study visits. The second visit will take place when the disease progression or death is occurs or in a year after the first visit whichever happens first. Data will be entered in the eCRF. The site investigator will be responsible for ensuring that all required data is collected and entered into the eCRF with the involvement of clinical research organization.

It is estimated that approximately 300 patients will be enrolled in the first stage. After interim analysis total number of the patients can be increased, depending on the number of NGS failures. It is estimated that approximately 30 sites in total will be participating in the study.
