ARCTIC: Liquid Biomarkers in Prostate Cancer

This study is for men with metastatic castration-resistant prostate cancer. Researchers want to understand if certain genes or proteins, called "biomarkers," found in circulating tumor cells (CTCs) can predict how well patients will respond to their standard hormonal therapies. CTCs are cancer cells that break away from a tumor and enter the bloodstream. By studying these biomarkers, the goal is to learn which patients might benefit most from specific treatments. The study will follow participants for up to three years to compare how long patients live without their cancer getting worse (progression-free survival) based on whether they have certain biomarkers.

Study design

    PFS which is defined as the time from date of study enrollment to radiographic or clinical progression or death. Radiographic progression will be defined by Prostate Cancer Working Group 3 (PCWG3) criteria for soft tissue and bone metastases and will not include PSA changes alone. Clinical progression will be defined as clinical deterioration requiring a change in therapy, such as a pathologic fracture or symptomatic skeletal event or pain progression in the absence of imaging progression.
