Genomic Biomarker-Selected Umbrella Neoadjuvant Study for High Risk Localized Prostate Cancer

Is NCT04812366 recruiting? Yes, currently enrolling (May 2026). This Phase 2 trial studies multiple treatments for prostate cancer.

Phase 2RecruitingUniversity of British ColumbiaNCT04812366Data as of May 2026

Treatment: Apalutamide 60mg Tab · Abiraterone Acetate 250mg · Prednisone 5mg Tab · Docetaxel · Niraparib 100mg Oral Capsule · AtezolizumabThe objective of this study is to see if providing an appropriate therapy based on the genomic testing of prostate tumour tissue will result in an improved clinical response. Each participant will be treated with 8 weeks of a luteinizing hormone-releasing hormone agonist (LHRHa) plus apalutamide (APA) while genome sequence characterization is being done. Participants with biopsy specimens deemed unevaluable for genomic testing will remain on LHRHa plus APA for an additional 16 weeks. Participants with evaluable tissue will be assigned to one of the open-label sub-studies on the basis of genomic profiling results. Within each group, they will be randomized to a specific treatment arm either LHRHa plus APA alone or adding abiraterone acetate and prednisone, docetaxel or niraparib. The study will evaluate the response rate and outcomes after radical prostatectomy in each arm of the trial.
