Stockholm3 Test Validation in Men on Active Surveillance in Switzerland (CHAS3 Trial)
Multicenter Validation of the Stockholm3 Test on Men on Active Surveillance: the CHAS3-Trial
Source: ClinicalTrials.gov · Last updated 22 Jun 2026
Brief summary (registry, in English)
The CHAS3 trial studies whether the Stockholm3 blood test can reliably detect if prostate cancer becomes more aggressive in men who are being carefully monitored instead of treated right away (active surveillance). The goal is to see if this test can help doctors safely follow patients with fewer invasive procedures, such as repeated biopsies.
