Pancreatic Cancer Screening Using the Enzeavour Assay in Japan (ENZEAVOUR FS)
Pancreatic Cancer Screening Using Single-Molecule Enzyme Activity-Based Liquid Biopsy, Enzeavour: A Single-Arm Interventional Feasibility Study Protocol in Japan
研究概览
详细说明
Pancreatic cancer is often diagnosed at an advanced stage, and an effective population-based screening strategy has not been established. The Enzeavour Pancreatic Cancer assay is a blood-based test that quantifies the activity of three specific enzymes at a single-molecule level and integrates four biomarkers into a composite Enzeavour Score.
This nationwide, multicenter, prospective, single-arm feasibility study evaluates the Enzeavour assay in routine health checkups and cancer screening in Japan. Approximately 10,000 asymptomatic adults will be enrolled. Participants with an Enzeavour Score greater than 0.369 will be referred for diagnostic work-up as clinically indicated. This study uses a partial verification design with 12-month follow-up for pre-specified subgroups and aims to generate real-world estimates of pancreatic cancer detection rate and positive predictive value for future trial planning.

实验性的:Enzeavour Screening Pathway
Participants undergo peripheral blood collection for the Enzeavour Pancreatic Cancer assay as part of a routine health checkup or organized cancer screening visit.
Participants with a positive assay result, defined as an Enzeavour Score greater than 0.369, are referred for diagnostic work-up, including MRCP, EUS, or contrast-enhanced CT, as clinically indicated.
|
A blood-based diagnostic assay that quantifies the activity of three specific enzymes at a single-molecule level.
Four biomarkers derived from these measurements are integrated into a composite Enzeavour Score using a predefined discriminant function.
Participants with a score above the pre-specified cut-off of 0.369 are considered test-positive and referred for diagnostic work-up.
