Frequently asked questions

  • Who is Freenome?

    Freenome, a biotechnology company, has pioneered a comprehensive platform for early cancer detection using a routine blood draw. The company combines its expertise in molecular biology with advanced computational biology and machine learning to recognize disease-associated patterns among billions of biomarkers.

  • What is the purpose of the PREEMPT CRC clinical trial?

    PREEMPT CRC is Freenome’s prospective clinical trial that is enrolling about 25,000 average-risk individuals. The trial aims to validate a blood test that can provide an accurate, convenient, and patient-friendly option to those undergoing screening for CRC and to support its submission for approval by the U.S. Food and Drug Administration.

  • Where is the clinical trial taking place?

    Eligible people across the U.S. (except for Hawaii) can participate. In response to COVID-19 and to make the trial more accessible, Freenome has implemented an approach that allows patients to enroll no matter where they live.

  • How long will the clinical trial last?

    The study is projected to be completed by the end of 2021.

  • If I participate, how will I receive my test results?

    The results of your colonoscopy will come from your doctor, in the same way it would have if you did not participate in this trial.

  • Will I be compensated?

    We will provide a stipend of up to $100 to those who enroll and complete the requirements of the study.
